Description

Technical Field

[0001] The present invention relates to an electrical connector for connection by inserting a plurality of arranged needle-shaped object-side connecting parts, and the electrical connector comprises: a fixed housing, which is set to a substrate; a movable housing, which is mounted on the fixed housing in a manner that can be displaced relative to the fixed housing; and a plurality of terminals, which support the movable housing so that it can be displaced relative to the fixed housing. Background Art

[0002] In the past, when connecting a plurality of arranged needle-shaped object-side connecting parts to a substrate, an electrical connector that is provided on the substrate and into which the plurality of needle-shaped object-side connecting parts are inserted for connection is used. As such an electrical connector, a structure is used, which comprises: a fixed housing provided to the substrate; a movable housing mounted on the fixed housing in a manner that can be displaced relative to the fixed housing; and a plurality of terminals that support the movable housing on the fixed housing in a manner that can be displaced relative to the fixed housing and are electrically connected to the object-side connecting parts. In such an electrical connector, the movable housing is supported to be displaceable relative to the fixed housing, so that the misalignment between the substrate and the object-side connecting parts can be absorbed. For example, in a state where the object-side connecting part is connected to the substrate via the electrical connector, even if vibration on the substrate side is generated, the vibration generated on the substrate can be absorbed by the terminals between the substrate and the object-side connecting part, and the vibration can be suppressed from being transmitted to the object-side connecting part. As such an electrical connector, for example, the electrical connectors disclosed in Patent Documents 1 and 2 are known.

[0003] The electrical connector disclosed in patent document 1 is configured to include: a fixed shell 4, which is set to a substrate P; a movable shell 5, which is installed on the fixed shell 4 in a manner that can be displaced relative to the fixed shell 4; and a plurality of terminals 3, which support the movable shell 5 on the fixed shell 4 and are electrically connected to a plurality of pin terminals T which are needle-shaped object side connecting parts.

[0004] The electric connector disclosed in Patent Document 2 is configured to include: a fixed housing 31, which is provided on a substrate 24b; a movable housing 32, which is mounted on the fixed housing 31 in a manner that can be displaced relative to the fixed housing 31; and a plurality of connector terminals 33, which support the movable housing 32 on the fixed housing 31 and are electrically connected to a plurality of pin terminals 12, which are pin-shaped counterpart connection members. In addition, the plurality of pin terminals 12 arranged in an array are held in an external connection housing 11.

[0009] Problems to be solved by the invention

[0010] When connecting the plurality of pin terminals T arranged in a row to the electrical connector disclosed in Patent Document 1, the plurality of pin terminals T are respectively inserted into the plurality of insertion ports 26 provided in the movable housing 5. When the plurality of pin terminals T are respectively inserted into the plurality of insertion ports 26 of the movable housing 5, each pin terminal T is electrically connected to each terminal 3 arranged inside the insertion port 26. However, if the plurality of pin terminals T arranged in a row are inserted into the movable housing 5 at a position offset from the plurality of insertion ports 26 of the movable housing 5, it is difficult to properly insert the pin terminals T into the insertion ports 26 of the movable housing 5. In this case, the pin terminals T come into contact with the partition walls 24 between the adjacent insertion ports 26 on the movable housing 5 and the lateral walls 22, 22 on both sides of the plurality of insertion ports 26 on the movable housing 5, and there is a problem that it is difficult to properly insert the plurality of pin terminals T into the plurality of insertion ports 26.

[0011] When connecting the plurality of pin terminals 12 arranged in a row to the electric connector disclosed in Patent Document 2, the plurality of pin terminals 12 are respectively inserted into the plurality of insertion ports 39 provided in the movable housing 32. When the plurality of pin terminals 12 are respectively inserted into the plurality of insertion ports 39 of the movable housing 32, each pin terminal 12 is electrically connected to each connector terminal 33 arranged inside the insertion port 39. In the structure disclosed in Patent Document 2, a guide mechanism is provided for guiding the plurality of pin terminals 12 in the insertion direction of the movable housing 32 when the plurality of pin terminals 12 arranged in a row are inserted into the movable housing 32 at positions offset from the plurality of insertion ports 39 of the movable housing 32. The guide mechanism is provided in the movable housing 32 of the electric connector and the external connection housing 11 that holds the plurality of pin terminals 12 arranged in a row. In the external connection housing 11, as a guide mechanism, guide protrusions 15 are provided on both sides of the plurality of pin terminals 12, and the guide protrusions 15 protrude greatly in the insertion direction of the plurality of pin terminals 12 into the movable housing 32. The movable housing 32 is provided with a structure that extends greatly on both sides of the plurality of insertion ports 39 and forms a surface for guiding the guide protrusion 15. Therefore, the structure disclosed in Patent Document 2 has a problem that the structure of the electric connector and the object to be connected to the electric connector becomes larger and more complicated.

[0012] In view of the above circumstances, an object of the present invention is to provide an electrical connector that can appropriately and easily insert a plurality of aligned needle-shaped mating-side connecting members for connection, while also preventing the structure from becoming larger and more complicated.

[0013] Means for solving problems

[0014] (1) An electrical connector according to one aspect of the present invention for achieving the above-mentioned purpose relates to an electrical connector into which a plurality of arranged needle-shaped object-side connecting parts are inserted for connection. Furthermore, the electrical connector according to one aspect of the present invention is characterized in that it comprises: a fixed housing, which is provided on a substrate; a movable housing, which is mounted on the fixed housing in a manner that allows displacement relative to the fixed housing, and a plurality of terminals, which support the movable housing so as to be displaceable relative to the fixed housing and are respectively electrically connected to the plurality of object-side connecting parts, wherein the movable housing is provided with: a guide portion, in which an opening for inserting the plurality of object-side connecting parts is provided, the guide portion guides the plurality of object-side connecting parts inserted into the opening to be accommodated inside the movable housing; and a plurality of insertion holes, in which the plurality of insertion holes are arranged in an array inside the guide portion, for the plurality of object-side connecting parts guided by the guide portion to be inserted into the opening. The object-side connecting parts are respectively inserted, and a first inclined surface is provided on the inner wall of the guide portion at both end sides in the arrangement direction of the plurality of insertion holes, that is, in the width direction, and the first inclined surface is inclined relative to the height direction in the following manner: it faces the height direction and extends in a cone shape toward the outside of the width direction to the opening, and the height direction is the direction in which the plurality of object-side connecting parts are inserted into the guide portion, that is, the opposite direction of the insertion direction, and a second inclined surface is provided between the adjacent insertion holes in the width direction, and the second inclined surface is inclined relative to the height direction in the following manner: it faces the insertion direction and extends in a cone shape toward the entrance of the insertion hole for inserting the object-side connecting part,

[0015] The dimension of the first inclined surface in the width direction is larger than the dimension of the second inclined surface in the width direction, and the dimension of the first inclined surface in the height direction is larger than the dimension of the second inclined surface in the height direction.

[0016] According to this structure, when a plurality of needle-shaped object-side connection components arranged in an array are connected to the electrical connector, the plurality of object-side connection components are inserted into the opening of the guide portion of the movable housing. The plurality of object-side connection components inserted into the opening of the guide portion of the movable housing are respectively inserted into the plurality of insertion holes on the inner side of the guide portion when the insertion positions are not offset. And the plurality of object-side connection components respectively inserted into the plurality of insertion holes are respectively electrically connected to the plurality of terminals. On the other hand, when the plurality of object-side connection components inserted into the opening of the guide portion of the movable housing are inserted into the opening in a state where the insertion positions are offset in the width direction, the terminal end of the object-side connection component on one side of the two end sides in the width direction of the plurality of object-side connection components abuts against the first inclined surface on one side of the two end sides in the width direction of the inner wall of the guide portion. In addition, regarding the first inclined surface inclined toward the height direction and toward the outer side in the width direction on the two end side surfaces of the inner wall of the guide portion in the width direction, the first inclined surface is set to be larger in the height direction and larger in the width direction than the second inclined surface inclined toward the entrance of the insertion hole between adjacent insertion holes. Therefore, when a plurality of object-side connection components arranged in a row are inserted into the opening of the guide portion in a state staggered in the width direction, before the tip portions of the plurality of object-side connection components abut against the second inclined surface that reaches the plurality of insertion holes, the tip portions of the object-side connection components on one side of the two end sides in the width direction of the plurality of object-side connection components abut against the first inclined surface on one side of the two end sides in the width direction of the inner wall of the guide portion. And the object-side connection components on one side of the two end sides in the width direction are inserted into the inner side of the opening while sliding along the first inclined surface. Thus, the plurality of object-side connection components arranged in a row move together with the object-side connection components on one side of the two end sides in the width direction of the opening while sliding along the first inclined surface, and are inserted into the inner side of the guide portion while being guided by the first inclined surface. When the plurality of object-side connection components are inserted into the inner side of the guide portion while being guided along the inclination direction of the first inclined surface, they are then respectively inserted into the plurality of insertion holes. Therefore, even when a plurality of object-side connection components are inserted into the movable housing in a state where the insertion positions are staggered in the width direction, the plurality of object-side connection components are inserted into the inner side of the guide portion while being guided along the inclination direction of the first inclined surface, and are properly inserted into the plurality of insertion holes. Therefore, the operation of inserting a plurality of arranged needle-shaped object-side connection components into the electrical connector for connection can be properly and easily performed. In addition, according to the above-mentioned structure, in the movable housing, the operation of inserting a plurality of arranged needle-shaped object-side connection components into the electrical connector for connection can be properly and easily performed with a simple structure in which the first inclined surface is provided at both end sides in the width direction of the guide portion provided with an opening. Therefore, it is possible to suppress the enlargement and complication of the structure of the electrical connector and the object side connected to the electrical connector.

[0017] As described above, according to the above configuration, it is possible to provide an electrical connector that can appropriately and easily perform the operation of inserting a plurality of aligned needle-shaped mating-side connecting members for connection, while also preventing the structure from becoming larger and more complicated.

[0018] (2) It may also be that the smaller angle between the direction in which the first inclined surface is inclined relative to the height direction and the width direction is greater than the smaller angle between the direction in which the second inclined surface is inclined relative to the height direction and the width direction.

[0019] When the smaller angle of the angles formed by the direction in which the first inclined surface is inclined relative to the height direction and the width direction is equal to the smaller angle of the angles formed by the direction in which the second inclined surface is inclined relative to the height direction and the width direction, when the plurality of object-side connection components are inserted into the inner side of the guide portion and reach the same height position as the second inclined surface while being guided along the inclined direction of the first inclined surface, they are then guided along the first inclined surface and the second inclined surface and inserted into the plurality of insertion holes. In contrast, according to the above-mentioned structure, the smaller angle of the angles formed by the direction in which the first inclined surface is inclined relative to the height direction and the width direction is set to be larger than the smaller angle of the angles formed by the direction in which the second inclined surface is inclined relative to the height direction and the width direction. Thus, even if the plurality of object-side connection components are inserted into the inner side of the guide portion and reach the same height position as the second inclined surface while being guided along the inclined direction of the first inclined surface, they hardly slide in contact with the second inclined surface, and continue to be guided along the first inclined surface and inserted into the plurality of insertion holes. In this way, the plurality of object-side connecting members inserted into the opening of the movable housing are guided along the first inclined surface and inserted into the plurality of insertion holes without sliding contact with the second inclined surface. Therefore, the operation of properly inserting and connecting the plurality of needle-shaped object-side connecting members arranged in an array can be performed more smoothly and easily.

[0020] (3) It may also be that a third inclined surface is provided on the inner wall of the guide portion at both end sides in the front-to-back direction, the front-to-back direction being a direction perpendicular to the width direction and the height direction, and the third inclined surface is inclined relative to the height direction in the following manner: it faces the height direction and extends in a conical manner toward the outside of the front-to-back direction to the opening, and the dimension of the third inclined surface in the height direction is greater than the dimension of the second inclined surface in the height direction.

[0021] According to this structure, when a plurality of object-side connecting components inserted into the opening of the guide portion of the movable housing are inserted into the opening in a state where the insertion positions are staggered in the front-to-back direction, the terminal ends of the plurality of object-side connecting components abut against the third inclined surface on one side of the two end sides in the front-to-back direction of the inner wall of the guide portion. In addition, regarding the third inclined surface arranged on the two end sides of the inner wall of the guide portion in the front-to-back direction toward the height direction and toward the outside in the front-to-back direction, the third inclined surface is set to be larger in the height direction than the second inclined surface inclined toward the entrance of the insertion hole between adjacent insertion holes. Therefore, when a plurality of object-side connecting components arranged in a row are inserted into the opening of the guide portion in a state where they are staggered in the front-to-back direction, before the terminal ends of the plurality of object-side connecting components reach the same height position as the second inclined surface reaching each side of the plurality of insertion holes, the terminal ends of the plurality of object-side connecting components abut against the third inclined surface on one side of the two end sides in the front-to-back direction of the inner wall of the guide portion. Furthermore, the plurality of object-side connecting components arranged in a row are inserted into the inner side of the opening while sliding along the third inclined surface, and are inserted into the inner side of the guide portion guided by the third inclined surface. When the plurality of object-side connection components are inserted into the inner side of the guide portion while being guided along the inclined direction of the third inclined surface, they are then respectively inserted into the plurality of insertion holes. Therefore, even when the plurality of object-side connection components are inserted into the movable housing in a state where the insertion positions are staggered in the front-back direction, the plurality of object-side connection components are inserted into the inner side of the guide portion while being guided along the inclined direction of the third inclined surface, and are appropriately inserted into the plurality of insertion holes. Therefore, the operation of inserting the plurality of needle-shaped object-side connection components arranged in an array into the electrical connector for connection can be appropriately and easily performed.

[0022] (4) An electrical connector according to one aspect of the present invention for achieving the above-mentioned purpose involves a connection through insertion of a plurality of needle-shaped counterpart connection parts arranged in two rows. Furthermore, the electrical connector according to one aspect of the present invention is characterized in that the electrical connector comprises: a fixed housing, which is provided on a substrate; a movable housing, which is mounted on the fixed housing in a manner that allows displacement relative to the fixed housing; and a plurality of terminals, which support the movable housing so as to be displaceable relative to the fixed housing and are respectively electrically connected to the plurality of counterpart connection parts, wherein the movable housing is provided with: a guide portion, in which an opening is provided for inserting the plurality of counterpart connection parts, the guide portion guides the plurality of counterpart connection parts inserted into the opening to be accommodated inside the movable housing; and a plurality of insertion holes, which are arranged in two rows inside the guide portion, into which the plurality of counterpart connection parts guided by the guide portion are respectively inserted, and on the inner wall of the guide portion, the plurality of insertion holes are arranged in the arrangement of the plurality of insertion holes. A first inclined surface is provided at both end sides in the arrangement direction of the two rows, i.e., the width direction, and the first inclined surface is inclined relative to the height direction in the following manner: it faces the height direction and extends in a conical manner to the opening toward the outside of the width direction, and the height direction is the direction in which the plurality of object-side connecting components are inserted into the guide portion, i.e., the opposite direction of the insertion direction, and a second inclined surface is provided between the adjacent insertion holes in the width direction, and the second inclined surface is inclined relative to the height direction in the following manner: it faces the insertion direction and extends in a conical manner toward the entrance of the insertion hole for inserting the object-side connecting component, and the size of the first inclined surface in the width direction is larger than the size of the second inclined surface in the width direction, and the size of the first inclined surface in the height direction is larger than the size of the second inclined surface in the height direction.

[0023] According to this structure, when the electrical connector is connected to a plurality of needle-shaped counterpart connection components arranged in two rows, the plurality of counterpart connection components are inserted into the opening of the guide portion of the movable housing. The plurality of counterpart connection components inserted into the opening of the guide portion of the movable housing are respectively inserted into the plurality of insertion holes on the inner side of the guide portion when the insertion positions are not offset. And the plurality of counterpart connection components respectively inserted into the plurality of insertion holes are respectively electrically connected to the plurality of terminals. On the other hand, when the plurality of counterpart connection components inserted into the opening of the guide portion of the movable housing are inserted into the opening in a state where the insertion positions are offset in the width direction, the terminal end of the counterpart connection component on one side of the two end sides in the width direction of the plurality of counterpart connection components arranged in two rows abuts against the first inclined surface on one side of the two end sides in the width direction of the inner wall of the guide portion. In addition, regarding the first inclined surface that is inclined toward the height direction and toward the outside in the width direction on the side surfaces at both ends of the inner wall of the guide in the width direction, the first inclined surface is set to have a larger dimension in the height direction and a larger dimension in the width direction than the second inclined surface that is inclined toward the entrance of the insertion hole between the adjacent insertion holes in the width direction. Therefore, when a plurality of object-side connection components arranged in two rows are inserted into the opening of the guide in a state of being staggered in the width direction, before the end portions of the plurality of object-side connection components abut against the second inclined surface that reaches the plurality of insertion holes, the end portions of the object-side connection components on one side of the two ends in the width direction of the plurality of object-side connection components abut against the first inclined surface on one side of the two ends in the width direction of the inner wall of the guide. And the object-side connection component on one side of the two ends in the width direction is inserted into the inside of the opening while sliding along the first inclined surface. As a result, the plurality of object-side connection components arranged in two rows move together with the object-side connection component on one side of the two ends in the width direction of the opening while sliding along the first inclined surface, and are inserted into the inside of the guide guided by the first inclined surface. When a plurality of object-side connection components are inserted into the inner side of the guide portion while being guided along the inclination direction of the first inclined surface, they are then respectively inserted into the plurality of insertion holes. Therefore, even in the case where a plurality of object-side connection components are inserted into the movable housing in a state where the insertion positions are staggered in the width direction, the plurality of object-side connection components are inserted into the inner side of the guide portion while being guided along the inclination direction of the first inclined surface, thereby being properly inserted into the plurality of insertion holes. Therefore, the operation of inserting a plurality of needle-shaped object-side connection components arranged in two rows into the electrical connector for connection can be properly and easily performed. In addition, according to the above-mentioned structure, in the movable housing, the operation of inserting a plurality of needle-shaped object-side connection components arranged in two rows into the electrical connector for connection can be properly and easily performed with a simple structure in which the first inclined surface is provided on both end sides in the width direction of the guide portion provided with an opening.Therefore, it is possible to suppress the increase in size and complexity of the structure of the electric connector and the counterpart to be connected to the electric connector.

[0024] As described above, according to the above configuration, it is possible to provide an electrical connector that can appropriately and easily perform the operation of inserting a plurality of needle-shaped counterpart connection members arranged in two rows for connection, while suppressing increase in size and complexity of the structure.

[0025] (5) It may also be that the smaller angle of the angles formed by the direction in which the first inclined surface is inclined relative to the height direction and the width direction is greater than the smaller angle of the angles formed by the direction in which the second inclined surface is inclined relative to the height direction and the width direction.

[0026] In the case where the smaller angle of the angles formed by the direction in which the first inclined surface is inclined relative to the height direction and the width direction is equal to the smaller angle of the angles formed by the direction in which the second inclined surface is inclined relative to the height direction and the width direction, when the plurality of counterpart side connection components are guided along the inclined direction of the first inclined surface and inserted into the inner side of the guide portion and reach the same height position as the second inclined surface, they are then guided along the first inclined surface and the second inclined surface and inserted into the plurality of insertion holes. In contrast, according to the above-mentioned structure, the smaller angle of the angles formed by the direction in which the first inclined surface is inclined relative to the height direction and the width direction is set to be larger than the smaller angle of the angles formed by the direction in which the second inclined surface is inclined relative to the height direction and the width direction. Thus, even if the plurality of counterpart side connection components are guided along the inclined direction of the first inclined surface and inserted into the inner side of the guide portion and reach the same height position as the second inclined surface, they are hardly in sliding contact with the second inclined surface, and continue to be guided along the first inclined surface and inserted into the plurality of insertion holes. In this way, the plurality of counterpart connection members inserted into the opening of the movable housing are guided along the first inclined surface and inserted into the plurality of insertion holes without sliding contact with the second inclined surface. Therefore, the operation of properly inserting and connecting the plurality of needle-shaped counterpart connection members arranged in two rows can be performed more smoothly and easily.

[0027] (6) It may also be that a third inclined surface is provided on the inner wall of the guide portion at both end sides in the front-to-back direction, the front-to-back direction being a direction perpendicular to the width direction and the height direction, the third inclined surface is inclined relative to the height direction in the following manner: it faces the height direction and extends in a conical manner toward the outside of the front-to-back direction to the opening, a fourth inclined surface is provided between the adjacent insertion holes in the front-to-back direction, the fourth inclined surface is inclined relative to the height direction in the following manner: it faces the insertion direction and extends in a conical manner toward the entrance of the insertion hole, the size of the third inclined surface in the front-to-back direction is larger than the size of the fourth inclined surface in the front-to-back direction, and the size of the third inclined surface in the height direction is larger than the size of the fourth inclined surface in the height direction.

[0028] According to this structure, when a plurality of needle-shaped object-side connection components arranged in two rows are inserted into the opening of the guide portion of the movable housing in a state where the insertion positions are staggered in the front-to-back direction, the tip of the object-side connection components arranged in the row on one side of the plurality of object-side connection components arranged in the two rows abuts against the third inclined surface on one side of the two end sides in the front-to-back direction of the inner wall of the guide portion. In addition, regarding the third inclined surface arranged in the height direction and the outer side in the front-to-back direction on the two end sides of the inner wall of the guide portion in the front-to-back direction, the third inclined surface is set to have a larger dimension in the height direction and a larger dimension in the front-to-back direction than the fourth inclined surface inclined toward the entrance of the insertion hole between adjacent insertion holes in the front-to-back direction. Therefore, when a plurality of object-side connection components arranged in two rows are inserted into the opening of the guide portion in a state where they are staggered in the front-to-back direction, before the tip of the plurality of object-side connection components abuts against the fourth inclined surface reaching each side of the plurality of insertion holes, the tip of the object-side connection components arranged in the row on one side of the front-to-back direction abuts against the third inclined surface on one side of the two end sides in the front-to-back direction of the inner wall of the guide portion. Furthermore, a plurality of object side connection components are inserted into the inner side of the opening while sliding in contact along the third inclined surface. Thus, a plurality of object side connection components arranged in two rows move together with the object side connection components arranged in the row on one side of the front-to-back direction of the opening while sliding in contact along the third inclined surface, and are guided by the third inclined surface to be inserted into the inner side of the guide portion. When a plurality of object side connection components are guided along the inclined direction of the third inclined surface to be inserted into the inner side of the guide portion, they are then respectively inserted into a plurality of insertion holes. Therefore, even in the case where a plurality of object side connection components are inserted into the movable housing in a state where the insertion positions are staggered in the front-to-back direction, a plurality of object side connection components are guided along the inclined direction of the third inclined surface to be inserted into the inner side of the guide portion, and are properly inserted into the plurality of insertion holes. Therefore, the operation of inserting a plurality of needle-shaped object side connection components arranged in two rows into the electrical connector for connection can be properly and easily performed.

[0029] (7) It may also be that the smaller angle of the angles formed by the direction in which the third inclined surface is inclined relative to the height direction and the front-to-back direction is greater than the smaller angle of the angles formed by the direction in which the fourth inclined surface is inclined relative to the height direction and the front-to-back direction.

[0030] In the case where the smaller angle of the angles formed by the direction in which the third inclined surface is inclined relative to the height direction and the front-back direction is equal to the smaller angle of the angles formed by the direction in which the fourth inclined surface is inclined relative to the height direction and the front-back direction, when the plurality of object-side connection components are inserted into the inner side of the guide portion and reach the same height position as the fourth inclined surface by being guided along the inclination direction of the third inclined surface, they are then guided along the third inclined surface and the fourth inclined surface and inserted into the plurality of insertion holes. In contrast, according to the above-mentioned structure, the smaller angle of the angles formed by the direction in which the third inclined surface is inclined relative to the height direction and the front-back direction is set to be larger than the smaller angle of the angles formed by the direction in which the fourth inclined surface is inclined relative to the height direction and the front-back direction. Thus, even if the plurality of object-side connection components are inserted into the inner side of the guide portion and reach the same height position as the fourth inclined surface by being guided along the inclination direction of the third inclined surface, they hardly come into sliding contact with the fourth inclined surface, but continue to be guided along the third inclined surface and inserted into the plurality of insertion holes. In this way, the plurality of counterpart connection members inserted into the opening of the movable housing are guided along the third inclined surface and inserted into the plurality of insertion holes without sliding contact with the fourth inclined surface. Therefore, the operation of properly inserting and connecting the plurality of needle-shaped counterpart connection members arranged in two rows can be performed more smoothly and easily.

The terminal holding wall 21, the side wall 23, the back wall 22, and the side wall 24 are arranged in a manner to form a rectangular cross section in a plane perpendicular to the insertion direction X1, and are integrally provided in a manner to constitute the four outer peripheral surfaces of the fixed housing 11. Therefore, the fixed housing 11 has a basic outer shape that is substantially rectangular.

[0100] The terminal retaining wall 21 is provided as a wall portion at one end side in the front-to-rear direction X4 of the fixed housing 11, and is configured to retain a plurality of terminals 13. A plurality of terminal fixing portions 25 are provided on the terminal retaining wall 21 for fixing the fixing portions 39 described later of each of the plurality of terminals 13 by pressing in. The plurality of terminal fixing portions 25 are provided on the end side in the insertion direction X1 in the terminal retaining wall 21, and are arranged along the width direction X3. The plurality of terminal fixing portions 25 each have a pair of pressing grooves for pressing in the fixing portions 39 described later of each of the plurality of terminals 13. By pressing the fixing portions 39 of the terminals 13 into the pair of pressing grooves of the terminal fixing portions 25, the terminals 13 are retained in a fixed state on the terminal retaining wall 21.

The plurality of slits 26 are respectively provided to penetrate the terminal holding wall 21 in a direction parallel to the front-rear direction X4, and extend in a direction parallel to the insertion direction X1. Parts of the movable spring portions 41 described later of the plurality of terminals 13 held in the terminal holding wall 21 are respectively arranged in the plurality of slits 26.

[0102] In addition, refer to Figures 3 to 5 , Figure 6 (B) Figures 7 to 9 In the fixed housing 11, a plurality of partition walls 27 extending from the terminal holding wall 21 toward the inner side of the fixed housing 11 are provided. The plurality of partition walls 27 are arranged along the width direction X3 on the inner side of the fixed housing 11. In addition, the plurality of partition walls 27 are extended from the terminal holding wall 21 on the inner side of the fixed housing 11 in a direction parallel to the front-rear direction X4. The plurality of partition walls 27 are provided as inner walls for dividing the plurality of terminals 13 arranged along the width direction X3 in the fixed housing 11. That is, in the fixed housing 11, the adjacent terminals 13 arranged along the width direction X3 are divided from each other by the partition walls 27.

[0103] In addition, refer to Figures 2 to 4 , Figure 6 , Figure 8 , Fig. 9A pair of mounting grooves 28 for mounting the movement limiting member 14 is provided in the fixed housing 11. The pair of mounting grooves 28 are provided at the ends in the height direction X2 on both ends of the width direction X3 in the fixed housing 11. The two ends of the movement limiting member 14 in the width direction X3 are pressed into and embedded in the pair of mounting grooves 28, so that the movement limiting member 14 is fixedly mounted on the fixed housing 11. In addition, the movement limiting member 14 is provided as a flat plate-shaped member, and is provided as a member for limiting the displacement amount of the movable housing 12 inserted and mounted in the fixed housing 11 in a clearance fit state relative to the fixed housing 11 and preventing the movable housing 12 from falling off from the fixed housing 11. In the state where the movable housing 12 is inserted into the fixed housing 11, the movement limiting member 14 is pressed into the mounting grooves 28 of the fixed housing 11 and fixed. In this state, the movement limiting member 14 is provided to abut against the convex portion 32 described later on the movable housing 12 in the height direction X2. The movement limiting member 14 mounted on the fixed housing 11 abuts against the protrusion 32 of the movable housing 12 inserted into the fixed housing 11 , thereby limiting the displacement of the movable housing 12 in the height direction X2 and preventing the movable housing 12 from falling off from the fixed housing 11 .

[0104] In addition, refer to Figures 3 to 9 In the fixed housing 11, an insertion port 29 is formed into which the movable housing 12 is inserted in a clearance fit state. The insertion port 29 is provided as a hole that opens the inner side of the fixed housing 11 to the outside, and is provided as a hole that opens toward the height direction X2. In addition, the insertion port 29 is provided as an area on the inner side of the fixed housing 11 surrounded by a plurality of partition walls 27, a side wall 23, a back wall 22, and a side wall 24 that protrude from the terminal holding wall 21 to the inner side of the fixed housing 11.

[0106] [Movable shell]

[0107] Fig.10 It is a perspective view showing the movable housing 12 of the electric connector 1 . Figures 1 to 8 , Fig.10 The movable housing 12 shown is inserted into the insertion port 29 of the fixed housing 11 in a clearance fit state, and is mounted to the fixed housing 11 in a manner that allows displacement relative to the fixed housing 11. In addition, the movable housing 12 is supported via a plurality of terminals 13 so as to be displaceable relative to the fixed housing 11. In addition, the movable housing 12 is provided with a main body 30 and a guide portion 31, the main body 30 is inserted into the insertion port 29 of the fixed housing 11, and the guide portion 31 guides the plurality of object side connection components 101a when the plurality of object side connection components 101a are inserted into the movable housing 12 to accommodate them inside the movable housing 12. The guide portion 31 is provided integrally with the main body 30 at the end side of the main body 30 in the height direction X2.

[0108] The main body 30 is formed as a part having a substantially rectangular basic outer shape extending long along the width direction X3, and is configured to be inserted into the insertion port 29 formed in the fixed housing 11 in a clearance fit state. Since the main body 30 is inserted into the insertion port 29 of the fixed housing 11 in a clearance fit state, it is configured to be relatively displaceable inside the insertion port 29. In addition, the main body 30 is supported by the fixed housing 11 via the plurality of terminals 13 in a state of being inserted into the insertion port 29.

[0109] In addition, the cross-sectional area of ​​the section perpendicular to the insertion direction X1 of the insertion port 29 into which the main body 30 is inserted is set to be larger than the cross-sectional area of ​​the section perpendicular to the insertion direction X1 of the portion of the main body 30 inserted into the insertion port 29. Therefore, when the main body 30 inserted into the insertion port 29 is displaced in the width direction X3 and the front-rear direction X4 within the insertion port 29, the displacement amount in the width direction X3 and the front-rear direction X4 is limited to less than a predetermined displacement amount. Therefore, in the electrical connector 1, the insertion port 29 of the fixed housing 11 is set to limit the displacement amount of the main body 30 of the movable housing 12 relative to the fixed housing 11 in either the width direction X3 and the front-rear direction X4.

[0110] Reference Figure 5 and Figure 7, in a state where the main body 30 is inserted into the insertion port 29 of the fixed housing 11 and supported by the fixed housing 11 via the plurality of terminals 13, gaps are formed between the two ends of the main body 30 in the width direction X3 and the pair of side walls 23 and the side wall 24. That is, a gap is formed between one end of the main body 30 in the width direction X3 and the side wall 23, and a gap is also formed between the other end of the main body 30 in the width direction X3 and the side wall 24. And, when the main body 30 is displaced in the width direction X3, the end of the main body 30 in the width direction X3 abuts against the side wall 23 or the side wall 24, and the displacement amount of the main body 30 in the width direction X3 is limited. Thus, the displacement amount of the main body 30 inserted into the insertion port 29 relative to the fixed housing 11 in the width direction X3 is limited. That is, in a state where the main body 30 is inserted into the insertion port 29, the displacement amount of the movable housing 12 relative to the fixed housing 11 in the width direction X3 is limited.

[0111] In addition, refer to Figure 6 and Figure 8 , when the main body 30 is inserted into the insertion port 29 of the fixed housing 11 and supported by the fixed housing 11 via the plurality of terminals 13, gaps are formed between the two ends of the main body 30 in the front-to-back direction X4 and the plurality of partition walls 27 and the back wall 22, respectively. That is, a gap is formed between one end of the main body 30 in the front-to-back direction X4 and the plurality of partition walls 27, and a gap is also formed between the other end of the main body 30 in the front-to-back direction X4 and the back wall 22. Furthermore, when the main body 30 is displaced in the front-to-back direction X4, the end of the main body 30 in the front-to-back direction X4 abuts against the plurality of partition walls 27 or the back wall 22, and the displacement amount of the main body 30 in the front-to-back direction X4 is limited. Thus, the displacement amount of the main body 30 inserted in the insertion port 29 relative to the fixed housing 11 in the front-to-back direction X4 is limited. That is, in a state where the main body 30 is inserted into the insertion port 29 , the displacement amount of the movable housing 12 relative to the fixed housing 11 in the front-rear direction X4 is restricted.

[0112] In addition, refer to Figures 5 to 8 , a plurality of holding chambers 30a are provided in the main body 30, and the plurality of holding chambers 30a respectively accommodate and hold the object side connection parts 40 described later in the plurality of terminals 13. The plurality of holding chambers 30a are provided as a plurality of space regions inside the main body 30, and are arranged along the width direction X3 on the inner side of the main body 30. In addition, the plurality of holding chambers 30a are respectively provided as roughly rectangular space regions on the inner side of the main body 30, and are opened toward the insertion direction X1. The object side connection part 40 of each terminal 13 is inserted into each holding chamber 30a from the opening of each holding chamber 30a toward the height direction X2. The object side connection part 40 of each terminal 13 is inserted into each holding chamber 30a in a pressed-in state and is held in each holding chamber 30a.

[0113] In addition, the main body 30 is provided with a convex portion 32 protruding along the front-to-back direction X4. The convex portion 32 has a substantially rectangular parallelepiped shape extending long along the width direction X3, and is provided as a portion protruding convexly from the main body 30 along the front-to-back direction X4. When the main body 30 is inserted into the insertion port 29, the convex portion 32 is provided protruding from the main body 30 toward the terminal retaining wall 21 side to which the terminal 13 is fixed in the fixed housing 11 in the front-to-back direction X4. In addition, the terminal 13 is provided with a fixing portion 39 as a portion fixed to the terminal retaining wall 21 of the fixed housing 11. Therefore, when the main body 30 is inserted into the insertion port 29, the convex portion 32 is provided protruding from the main body 30 toward one side of the fixing portion 39 to which the terminal 13 is fixed in the fixed housing 11 in the front-to-back direction X4.

[0114] In a state where the movable housing 12 is assembled to the fixed housing 11, the convex portion 32 protruding from the main body 30 along the front-to-back direction X4 is configured to protrude along the front-to-back direction X4 between the plurality of partition walls 27 of the fixed housing 11 and the movement limiting component 14 mounted on the fixed housing 11. Therefore, the convex portion 32 is configured to be opposite to the plurality of partition walls 27 of the fixed housing 11 in the insertion direction X1, and to be opposite to the movement limiting component 14 in the height direction X2. In addition, a gap is formed between the convex portion 32 and the plurality of partition walls 27 of the fixed housing 11, and a gap is also formed between the convex portion 32 and the movement limiting component 14. In addition, when the convex portion 32 displaced together with the movable housing 12 is displaced in the insertion direction X1, the convex portion 32 abuts against the plurality of partition walls 27, and the displacement amount of the movable housing 12 provided with the convex portion 32 in the insertion direction X1 is limited. In addition, when the convex portion 32 displaced together with the movable housing 12 is displaced in the height direction X2, the convex portion 32 abuts against the movement limiting member 14, and the displacement amount of the movable housing 12 provided with the convex portion 32 in the height direction X2 is limited. Therefore, when the movable housing 12 with the main body 30 inserted in the insertion port 29 of the fixed housing 11 is displaced in the direction of being pulled out from the insertion port 29, that is, in the height direction X2, the convex portion 32 of the movable housing 12 abuts against the movement limiting member 14, and the displacement amount of the movable housing 12 in the height direction X2 is limited, thereby preventing the movable housing 12 from coming off the fixed housing 11.

[0115] Reference Figures 1 to 8 , Fig.10The guide portion 31 is provided integrally with the main body 30 at the end side in the height direction X2 of the main body 30, and is provided as a portion on the end side in the height direction X2 in the movable housing 12. Furthermore, the guide portion 31 is provided as a portion that guides the plurality of object-side connection components 101a to be accommodated inside the movable housing 12 when the plurality of object-side connection components 101a are inserted into the movable housing 12. The guide portion 31 is provided with an opening 33 for inserting the plurality of object-side connection components 101a. The opening 33 opens toward the height direction X2 and opens in a state extending over the width direction X3, and the height direction X2 is a direction opposite to the insertion direction X1 in which the plurality of object-side connection components 101a are inserted into the guide portion 31. Furthermore, the guide portion 31 is configured to guide the plurality of object-side connection components 101a inserted into the opening 33 to be accommodated inside the movable housing 12.

[0116] In addition, a plurality of insertion holes 34 are arranged on the inner side of the guide portion 31, into which a plurality of object side connection parts 101a guided by the guide portion 31 are respectively inserted.

The substrate connection portion 38 is fixed to the surface of the substrate 100 by soldering, thereby being electrically and mechanically connected to the substrate 100.

The counterpart side connection portion 40 is provided as a connection portion as a female terminal, and has a cylindrical portion 40a, a spring contact portion 40b, and a press-fit portion 40c.

[0131] The cylindrical portion 40a of the object side connection portion 40 is provided as a portion formed by bending into a square cylindrical shape. When the object side connection portion 40 is held in the movable housing 12, the cylindrical portion 40a is inserted and held in the holding chamber 30a of the main body portion 30 of the movable housing 12. The cylindrical portion 40a is open in the height direction X2, and when the cylindrical portion 40a is inserted into the holding chamber 30a, the opening of the cylindrical portion 40a is arranged in a state opposite to the insertion hole 34. Furthermore, when the terminal 13 is connected to the object side connection component 101a, the object side connection component 101a inserted from the insertion hole 34 is inserted into the inner side of the cylindrical portion 40a in the holding chamber 30a.

When the terminal 13 is connected to the counterpart side connection component 101a, the spring contact portion 40b contacts and electrically connects with the counterpart side connection component 101a inserted from the insertion hole 34 of the movable housing 12 and inserted into the inside of the cylindrical portion 40a.

[0133] The press-in portion 40c of the partner-side connection portion 40 is provided adjacent to the cylindrical portion 40a, and is provided as a portion to be pressed into the main body portion 30 of the movable housing 12. When the cylindrical portion 40a is inserted into the holding chamber 30a of the main body portion 30 of the movable housing 12, the press-in portion 40c is pressed into the inner wall of the holding chamber 30a. By pressing the press-in portion 40c into the main body portion 30, the partner-side connection portion 40 is firmly held in the main body portion 30 of the movable housing 12.

[0134] Reference Figures 2 to 4 , Figure 6 , Figure 8 , Fig.13 The movable spring portion 41 is configured as a portion in the terminal 13 that connects the fixed portion 39 and the object side connection portion 40 as a whole and supports the object side connection portion 40 on the fixed portion 39 in a manner that allows displacement relative to the fixed portion 39. The movable spring portion 41 is configured as a slender leaf spring-shaped portion that is bent and extended multiple times. In addition, in the present embodiment, the movable spring portion 41 is configured to bend and extend approximately at a right angle toward the back wall 22 side in the front-to-back direction X4 after extending from the fixed portion 39 in the height direction X2, then bend and extend approximately at a right angle toward the insertion direction X1, and then bend and extend in a semicircular arc shape at approximately 180 degrees from the insertion direction X1 to the height direction X2, and be continuous with the object side connection portion 40.

In addition, the movable spring portion 41 of the terminal 13 arranged at a position on the two end sides in the width direction X3 in the electrical connector 1 is arranged in the fixed housing 11 so as to be bent and extended multiple times between the side wall 23 and the partition wall 27, or between the side wall 24 and the partition wall 27.

[0136] [Connection between a substrate and a mating connector using an electrical connector]

[0137] Next, the connection between the substrate 100 and the counterpart connector 101 using the above-mentioned electric connector 1 is described. On the substrate 100, for example, a conductive circuit pattern (not shown) is provided on the surface, and the electric connector 1 is mounted and connected to the substrate 100. When the electric connector 1 is provided on the substrate 100, the substrate connection parts 38 of the plurality of terminals 13 of the electric connector 1 are soldered to the substrate 100, and the pair of fixing members 15 of the electric connector 1 are also soldered to the substrate 100. Thus, the electric connector 1 is connected to the substrate 100.

[0138] When the electric connector 1 is connected to the substrate 100, the counterpart connector 101 is connected to the electric connector 1. Thus, the substrate 100 and the counterpart connector 101 are electrically connected via the electric connector 1. When the counterpart connector 101 is connected to the electric connector 1, a plurality of counterpart connection components 101a of the counterpart connector 101 are inserted into the movable housing 12. The plurality of counterpart connection components 101a are first inserted into the opening 33 of the guide portion 31 of the movable housing 12. The plurality of counterpart connection components 101a inserted into the opening 33 of the guide portion 31 are respectively inserted into the plurality of insertion holes 34 arranged in a row inside the guide portion 31. The counterpart connection components 101a inserted into the insertion holes 34 come into contact with the spring contact portion 40b of the counterpart connection portion 40 of the terminal 13 held inside the movable housing 12, and are electrically connected to the terminal 13. Thus, the electric connector 1 and the counterpart connector 101 are connected, and the substrate 100 and the counterpart connector 101 are electrically connected via the electric connector 1.

[0139] In the electrical connector 1, a movable housing 12 to which a plurality of counterpart-side connecting parts 101a of a counterpart-side connector 101 are connected is supported by a plurality of terminals 13 in a manner that allows displacement relative to a fixed housing 11 connected to a substrate 100. Therefore, even when a misalignment occurs between the substrate 100 and the counterpart-side connector 101, the misalignment can be absorbed by the relative displacement between the movable housing 12 and the fixed housing 11. For example, even when vibration occurs on the substrate 100 side, between the substrate 100 and the counterpart-side connector 101, the vibration generated on the substrate 100 side can be absorbed by the elastic deformation of the movable spring portion 41 of the terminal 13, thereby suppressing the transmission of the vibration to the counterpart-side connector 101.

[0140] [Connection operation between the counterpart connection component and the electrical connector]

[0141] Here, the operation when the plurality of needle-shaped counterpart connection components 101a arranged in the counterpart connector 101 are inserted into the electrical connector 1 for connection is further described. When the plurality of counterpart connection components 101a are inserted into the electrical connector 1, the plurality of counterpart connection components 101a are inserted into the movable housing 12 of the electrical connector 1. At this time, the plurality of counterpart connection components 101a are sometimes inserted in a state where the insertion positions are offset relative to the movable housing 12. Fig.14 This is a side view showing a state immediately before a plurality of needle-shaped mating connection members 101 a of the mating connector 101 are inserted into the electric connector 1 , and shows the electric connector 1 with the fixing housing 11 omitted. Fig.15 yes Fig.14 Cross-sectional view in the direction of the arrow at the CC line. Fig.14 and Fig.15 The figure shows a state where a plurality of counterpart-side connecting members 101 a are inserted into the movable housing 12 in a state where the insertion positions are shifted in the width direction X3 .

[0142] Reference Fig.14 and Fig.15When the plurality of counterpart-side connection components 101a are inserted into the movable housing 12, the plurality of counterpart-side connection components 101a are inserted into the opening 33 of the guide portion 31 of the movable housing 12. When the plurality of counterpart-side connection components 101a are inserted into the movable housing 12 in a state where the insertion positions are offset in the width direction X3 relative to the movable housing 12, the plurality of counterpart-side connection components 101a are inserted into the opening 33 at positions offset in the width direction X3 relative to the plurality of insertion holes 34 without overlapping in the insertion direction X1. When the plurality of counterpart-side connection components 101a inserted into the opening 33 of the guide portion 31 in a state where the insertion positions are offset in the width direction X3, the tip end portion of the counterpart-side connection component 101a on one of the two end sides in the width direction X3 of the plurality of counterpart-side connection components 101a abuts against the first inclined surface 35 on one of the two end sides in the width direction X3 of the inner wall of the guide portion 31. Furthermore, the dimension H1 of the first inclined surface 35 in the height direction X2 is set to be larger than the dimension H2 of the second inclined surface 36 in the height direction X2, and the dimension W1 of the first inclined surface 35 in the width direction X3 is set to be larger than the dimension W2 of the second inclined surface 36 in the width direction X3. Therefore, when the plurality of counterpart connection members 101a arranged in a row are inserted into the opening 33 of the guide portion 31 in a state of being staggered in the width direction X3, before the distal ends of the plurality of counterpart connection members 101a abut against the second inclined surfaces 36 reaching the plurality of insertion holes 34, the distal ends of the plurality of counterpart connection members 101a on one side of the two end sides in the width direction X3 of the plurality of counterpart connection members 101a abut against the first inclined surface 35 on one side of the two end sides in the width direction X3 of the inner wall of the guide portion 31.

[0143] Fig.16 as well as Fig.17 1 is a cross-sectional view showing a state in which a plurality of needle-shaped counterpart connection members 101a of the counterpart connector 101 are halfway inserted into the electric connector 1. Fig.14 The cross-sectional view at the position corresponding to the CC line position. In addition, Fig.16 is a diagram showing a plurality of object-side connecting components 101a from Fig.15 The state shown is further inserted into the inner side of the guide portion 31. Fig.17 is a diagram showing a plurality of object-side connecting components 101a from Fig.16 The state shown is a state further inserted into the inner side of the guide portion 31. Fig.16, when a plurality of object side connection components 101a are inserted into the opening 33 and the object side connection components 101a on one of the two end sides in the width direction X3 abut against the first inclined surface 35, the object side connection components 101a on one of the two end sides in the width direction X3 are inserted into the inner side of the opening 33 while sliding along the first inclined surface 35. As a result, the plurality of object side connection components 101a arranged in a row move in the insertion direction X1 together with the object side connection components 101a on one of the two end sides in the width direction X3 of the opening 33 while sliding along the first inclined surface 35. Therefore, the plurality of object side connection components 101a arranged in a row are guided by the first inclined surface 35 and inserted into the inner side of the guide portion 31. And, as Fig.17 As shown, when the plurality of object side connection components 101a are guided by the first inclined surface 35 and inserted into the inner side of the guide portion 31, they are then respectively guided to the plurality of insertion holes 34. When the plurality of object side connection components 101a are respectively guided to the plurality of insertion holes 34, they are directly inserted into the plurality of insertion holes 34. And, the plurality of object side connection components 101a respectively inserted into the plurality of insertion holes 34 respectively pass through the plurality of insertion holes 34, and contact the spring contact portion 40b of the object side connection portion 40 of the terminal 13 held on the inner side of the movable housing 12, thereby being electrically connected to the terminal 13 (refer to Figure 7 ).

[0144] Next, a description will be given of a case where a plurality of counterpart-side connecting members 101 a are inserted into the movable housing 12 in a state where the insertion positions are shifted in the front-rear direction X4 . Fig.18 This is a front view showing a state immediately before a plurality of needle-shaped mating connection members 101 a of the mating connector 101 are inserted into the electric connector 1 , and shows the electric connector 1 with the fixing housing 11 omitted. Fig.19 yes Fig.18 Cross-sectional view in the direction of the arrow at the DD line. Fig.18 and Fig.19 The figure shows a state where a plurality of counterpart-side connecting members 101 a are inserted into the movable housing 12 in a state where the insertion positions are shifted in the front-rear direction X4 .

[0145] Reference Fig.18 and Fig.19When the plurality of counterpart-side connection components 101a are inserted into the movable housing 12, the plurality of counterpart-side connection components 101a are inserted into the opening 33 of the guide portion 31 of the movable housing 12. When the plurality of counterpart-side connection components 101a are inserted in a state where the insertion positions are offset in the front-rear direction X4 relative to the movable housing 12, the plurality of counterpart-side connection components 101a are inserted into the opening 33 at positions that overlap in the insertion direction X1 and are offset in the front-rear direction X4 relative to the plurality of insertion holes 34. When the plurality of counterpart-side connection components 101a inserted into the opening 33 of the guide portion 31 are inserted into the opening 33 in a state where the insertion positions are offset in the front-rear direction X4, the distal ends of the plurality of counterpart-side connection components 101a abut against the third inclined surface 37 on one side of the two end sides in the front-rear direction X4 of the inner wall of the guide portion 31. In addition, the dimension H1 of the third inclined surface 37 in the height direction X2 is set to be larger than the dimension H2 of the second inclined surface 36 in the height direction X2. Therefore, when the multiple object side connecting parts 101a arranged in an array are inserted into the opening 33 of the guide portion 31 in a state where they are staggered in the front-to-back direction X4, before the terminal ends of the multiple object side connecting parts 101a reach the same height as the second inclined surfaces 36 that respectively reach the multiple insertion holes 34, the terminal ends of the multiple object side connecting parts 101a abut against the third inclined surface 37 on one side of the two end sides in the front-to-back direction X4 on the inner wall of the guide portion 31.

[0146] Fig. 20 1 is a cross-sectional view showing a state in which a plurality of needle-shaped counterpart connection members 101a of the counterpart connector 101 are halfway inserted into the electric connector 1.

Thus, the plurality of object-side connection components 101a arranged in a row are moved in the insertion direction X1 while sliding along the third inclined surface 37. Therefore, the plurality of object-side connection components 101a arranged in a row are guided by the third inclined surface 37 and inserted into the inner side of the guide portion 31. And, when the plurality of object-side connection components 101a are guided by the third inclined surface 37 and inserted into the inner side of the guide portion 31, they are then respectively guided to the plurality of insertion holes 34. When the plurality of object-side connection components 101a are respectively guided to the plurality of insertion holes 34, they are directly inserted into the plurality of insertion holes 34. Then, the plurality of counterpart connection members 101a respectively inserted into the plurality of insertion holes 34 respectively pass through the plurality of insertion holes 34, and contact the spring contact portion 40b of the counterpart connection portion 40 of the terminal 13 held inside the movable housing 12, thereby being electrically connected to the terminal 13 (see Figure 8 ).

[0147] [Functions and Effects of the First Embodiment]

And the plurality of counterpart connection members 101a respectively inserted into the plurality of insertion holes 34 are respectively electrically connected to the plurality of terminals 13. On the other hand, when the plurality of counterpart connection members 101a inserted into the opening 33 of the guide portion 31 of the movable housing 12 are inserted into the opening 33 in a state where the insertion positions are shifted in the width direction X3, the distal end of the counterpart connection member 101a on one side of the two end sides in the width direction X3 of the plurality of counterpart connection members 101a abuts against the first inclined surface 35 on one side of the two end sides in the width direction X3 of the inner wall of the guide portion 31. In addition, the first inclined surface 35 provided on the two end side surfaces in the width direction X3 of the inner wall of the guide portion 31 inclining toward the height direction X2 and toward the outside in the width direction X3 is set to have a larger dimension in the height direction X2 and a larger dimension in the width direction X3 than the second inclined surface 36 inclining toward the entrance of the insertion hole 34 between the adjacent insertion holes 34. Therefore, when the plurality of counterpart connection members 101a arranged in a row are inserted into the opening 33 of the guide portion 31 in a state where they are staggered in the width direction X3, before the distal ends of the plurality of counterpart connection members 101a abut against the second inclined surfaces 36 that reach the plurality of insertion holes 34, the distal ends of the counterpart connection members 101a on one side of the two end sides in the width direction X3 of the plurality of counterpart connection members 101a abut against the first inclined surfaces 35 on one side of the two end sides in the width direction X3 of the inner wall of the guide portion 31. Then, the counterpart connection member 101a on one side of the two end sides in the width direction X3 is inserted into the inner side of the opening 33 while sliding along the first inclined surfaces 35. Thus, the plurality of counterpart connection members 101a arranged in a row move together with the counterpart connection member 101a on one side of the two end sides in the width direction X3 of the opening 33 while sliding along the first inclined surfaces 35, and are inserted into the inner side of the guide portion 31 while being guided by the first inclined surfaces 35. When the plurality of counterpart-side connection members 101a are inserted into the inner side of the guide portion 31 while being guided along the inclination direction of the first inclination surface 35, they are then respectively inserted into the plurality of insertion holes 34. Therefore, even when the plurality of counterpart-side connection members 101a are inserted into the movable housing 12 in a state where the insertion positions are offset in the width direction X3, the plurality of counterpart-side connection members 101a are inserted into the inner side of the guide portion 31 while being guided along the inclination direction of the first inclination surface 35, and are appropriately inserted into the plurality of insertion holes 34.Therefore, the operation of inserting the plurality of needle-shaped counterpart connection members 101a arranged in a row into the electric connector 1 for connection can be properly and easily performed. In addition, according to the first embodiment, in the movable housing 12, the operation of inserting the plurality of needle-shaped counterpart connection members 101a arranged in a row into the electric connector 1 for connection can be properly and easily performed with a simple structure in which the first inclined surfaces 35 are provided on both end sides in the width direction X3 of the guide portion 31 provided with the opening 33. Therefore, it is possible to suppress the enlargement and complication of the structure of the electric connector 1 and the counterpart connector 101 connected to the electric connector 1.

[0149] As described above, according to the first embodiment, it is possible to provide an electric connector 1 that can appropriately and easily perform the operation of inserting and connecting a plurality of aligned needle-shaped counterpart connection members 101 a while suppressing an increase in size and complexity of the structure.

[0150] In addition, when the size of the smaller angle θ1 of the angles formed by the direction in which the first inclined surface 35 is inclined with respect to the height direction X2 and the width direction X3 is equal to the size of the smaller angle θ2 of the angles formed by the direction in which the second inclined surface 36 is inclined with respect to the height direction X2 and the width direction X3, when the plurality of counterpart-side connecting members 101a are guided into the inner side of the guide portion 31 along the inclination direction of the first inclined surface 35 and reach the same height position as the second inclined surface 36, they are then guided along the first inclined surface 35 and the second inclined surface 36 and inserted into the plurality of insertion holes 34. In contrast, according to the first embodiment, the size of the smaller angle θ1 of the angles formed by the direction in which the first inclined surface 35 is inclined with respect to the height direction X2 and the width direction X3 is set to be larger than the size of the smaller angle θ2 of the angles formed by the direction in which the second inclined surface 36 is inclined with respect to the height direction X2 and the width direction X3. Thus, even when the plurality of counterpart connection members 101a are guided along the inclination direction of the first inclined surface 35 and inserted into the inner side of the guide portion 31 and reach the same height position as the second inclined surface 36, they are hardly in sliding contact with the second inclined surface 36, but continue to be guided along the first inclined surface 35 and are respectively inserted into the plurality of insertion holes 34. In this way, the plurality of counterpart connection members 101a inserted into the opening 33 of the movable housing 12 are also guided along the first inclined surface 35 and are respectively inserted into the plurality of insertion holes 34 without hardly in sliding contact with the second inclined surface 36. Therefore, the operation of properly inserting and connecting the plurality of needle-shaped counterpart connection members 101a arranged in a row can be performed more smoothly and easily.

[0151] According to the first embodiment, when the plurality of counterpart-side connecting members 101a inserted into the opening 33 of the guide portion 31 of the movable housing 12 are inserted into the opening 33 in a state where the insertion positions are shifted in the front-rear direction X4, the distal ends of the plurality of counterpart-side connecting members 101a abut against the third inclined surface 37 on one side of the two end sides in the front-rear direction X4 of the inner wall of the guide portion 31. In addition, regarding the third inclined surface 37 provided on the two end side surfaces in the front-rear direction X4 of the inner wall of the guide portion 31 so as to be inclined toward the height direction X2 and toward the outer side in the front-rear direction X4, the dimension in the height direction X2 is set larger than the second inclined surface 36 inclined toward the entrance of the insertion hole 34 between the adjacent insertion holes 34. Therefore, when the plurality of counterpart connection members 101a arranged in a row are inserted into the opening 33 of the guide portion 31 in a state where they are staggered in the front-rear direction X4, the distal ends of the plurality of counterpart connection members 101a abut against the third inclined surface 37 on one side of the two end sides in the front-rear direction X4 on the inner wall of the guide portion 31 before the distal ends of the plurality of counterpart connection members 101a reach the same height position as the second inclined surface 36 of each of the plurality of insertion holes 34. Then, the plurality of counterpart connection members 101a arranged in a row are inserted into the inner side of the opening 33 while sliding along the third inclined surface 37, and are inserted into the inner side of the guide portion 31 while being guided by the third inclined surface 37. When the plurality of counterpart connection members 101a are inserted into the inner side of the guide portion 31 while being guided along the inclination direction of the third inclined surface 37, they are then respectively inserted into the plurality of insertion holes 34. Therefore, even when the plurality of counterpart-side connecting members 101a are inserted into the movable housing 12 in a state where the insertion positions are offset in the front-rear direction X4, the plurality of counterpart-side connecting members 101a are inserted into the inner side of the guide portion 31 while being guided along the inclination direction of the third inclined surface 37, and are properly inserted into the plurality of insertion holes 34. Therefore, the operation of inserting the plurality of needle-shaped counterpart-side connecting members 101a arranged in a row into the electric connector 1 for connection can be properly and easily performed.

Furthermore, the electric connector 2 is configured as an electric connector that is connected by inserting the plurality of needle-shaped counterpart connection parts 101a arranged in two rows in the counterpart connector 101.

However, in the electric connector 2, the plurality of terminals 13 are arranged in two rows along the width direction X3, and the plurality of needle-shaped counterpart side connection parts 101a arranged in two rows are inserted for connection, and accordingly, the structure related to the fixed housing 51 and the movable housing 52 is partially different from the electric connector 1 of the first embodiment described above.

[0158] In addition, in the following description of the electrical connector 2, Figure 21 to Figure 26As shown by arrows X1, X2, arrows X3 at both ends, and arrows X4 at both ends in the drawings described later, the insertion direction X1, the height direction X2, the width direction X3, and the front-back direction X4 of the electric connector 2 are defined. The insertion direction X1 is a direction in which a plurality of needle-shaped counterpart connection components 101a are inserted into the movable housing 52 in the electric connector 2 for connection. The plurality of needle-shaped counterpart connection components 101a are inserted into the guide portion 31 of the movable housing 52 relative to the movable housing 52. In addition, the insertion direction X1 is also a direction in which the movable housing 52 is inserted and mounted to the fixed housing 51. The height direction X2 is a direction opposite to the insertion direction X1. That is, the height direction X2 is a direction parallel to and opposite to the insertion direction X1, and is a direction opposite to the direction in which the plurality of counterpart connection components 101a are inserted into the movable housing 52. The width direction X3 is a direction in which a plurality of insertion holes 34 arranged in two rows on the inner side of the guide portion 31 of the movable housing 52 are arranged in two rows. The plurality of object-side connection members 101a arranged in two rows are inserted into the plurality of insertion holes 34 arranged in two rows. In addition, the width direction X3, which is the direction in which the plurality of insertion holes 34 are arranged in two rows on the inner side of the guide portion 31 of the movable housing 52, is also configured as the pitch direction in which the plurality of terminals 13 are arranged in two rows in the fixed housing 51. The front-to-back direction X4 is configured as a direction perpendicular to the height direction X2 and the width direction X3. That is, the front-to-back direction X4 is configured as a direction perpendicular to the height direction X2 and the insertion direction X1, and is also a direction perpendicular to the width direction X3.

[0159] Reference Figure 21 to Figure 26 The fixed housing 51 provided to the substrate 100 is configured to be substantially the same as the fixed housing 11 of the electrical connector 1, but unlike the fixed housing 11, a pair of terminal retaining walls 21 are provided instead of a back wall 22. That is, the fixed housing 51 is configured to have: a pair of terminal retaining walls 21 arranged opposite to each other in the front-to-back direction X4 and extending in parallel with each other, and a pair of side walls 23 and a side wall 24 extending perpendicularly to the pair of terminal retaining walls 21. One of the pair of terminal retaining walls 21 is configured to hold a wall portion of one row of a plurality of terminals 13 arranged in two rows along the width direction X3. And, the other of the pair of terminal retaining walls 21 is configured to hold a wall portion of another row of a plurality of terminals 13 arranged in two rows along the width direction X3.

[0160] The movable housing 52 installed in a relatively displaceable manner relative to the fixed housing 51 is constructed in substantially the same manner as the movable housing 12 of the electrical connector 1, but differs from the movable housing 12 in that the main body 30 and the guide portion 31 are constructed to allow the object-side connecting component 101a arranged in two rows to be inserted for connection.

[0161] In the main body 30 of the movable housing 52, a plurality of holding chambers 30a are arranged in two rows along the width direction X3. In the main body 30 of the movable housing 52, a plurality of holding chambers 30a in each row of the plurality of holding chambers 30a arranged in two rows are arranged corresponding to the plurality of insertion holes 34 arranged in two rows in the guide portion 31. In addition, a plurality of holding chambers 30a in one row of the plurality of holding chambers 30a arranged in two rows of the main body 30 of the movable housing 52 is configured to hold the counterpart side connection portion 40 of the plurality of terminals 13 in one row of the plurality of terminals 13 arranged in two rows in the electrical connector 2.

Furthermore, the guide portion 31 is provided as a portion for guiding the plurality of object side connection components 101a to be accommodated inside the movable housing 12 when the plurality of object side connection components 101a are inserted into the movable housing 12. The guide portion 31 is provided with an opening 33 for inserting the plurality of object side connection components 101a. The opening 33 opens toward the height direction X2 and opens in a state extending over the width direction X3, and the height direction X2 is a direction opposite to the insertion direction X1 in which the plurality of object side connection components 101a are inserted into the guide portion 31. Furthermore, the guide portion 31 is configured to guide the plurality of object side connection components 101a inserted into the opening 33 to be accommodated inside the movable housing 12.

[0163] In addition, on the inner side of the guide portion 31, a plurality of insertion holes 34 are arranged in two rows for inserting the plurality of object side connection parts 101a guided by the guide portion 31. The plurality of insertion holes 34 are arranged in two rows along the width direction X3 on the inner side of the guide portion 31. In addition, the direction in which the plurality of insertion holes 34 are arranged in two rows in the movable housing 52 constitutes the width direction X3 of the electrical connector 2. The plurality of insertion holes 34 are arranged in two rows at equal intervals in the width direction X3. The spacing dimension, i.e., the pitch dimension, of the plurality of insertion holes 34 arranged in two rows at equal intervals in the width direction X3 is set to be the same as the spacing dimension of the plurality of object side connection parts 101a arranged in two rows at equal intervals in the width direction X3 in the object side connector 101.

[0164] In addition, the plurality of insertion holes 34 are respectively opened along the height direction X2 on the inner side of the opening 33 of the guide portion 31. The plurality of insertion holes 34 are respectively communicated with the plurality of holding chambers 30a arranged in two rows along the width direction X3 on the inner side of the main body portion 30 of the movable housing 52 in the insertion direction X1. When the plurality of object-side connection components 101a are inserted into the guide portion 31 of the movable housing 52, they are inserted into the guide portion 31 from the opening 33. The plurality of object-side connection components 101a inserted from the opening 33 are arranged in two rows along the width direction X3 on the inner side of the opening 33, and are respectively inserted into the plurality of insertion holes 34 opened in the height direction X2. When the plurality of object-side connection components 101a are respectively inserted into the insertion holes 34, they are inserted into the holding chamber 30a through the insertion holes 34. The object-side connection component 101a inserted into the holding chamber 30a contacts the object-side connection portion 40 of the terminal 13 held in the holding chamber 30a. Each of the mating-side connecting members 101 a inserted into each of the insertion holes 34 comes into contact with the mating-side connecting portion 40 of each of the terminals 13 , so that each of the mating-side connecting members 101 a and each of the terminals 13 are electrically connected.

With respect to the insertion holes 34 arranged at both end sides in the width direction X3, the insertion holes 34 are arranged adjacently only on one side in the width direction X3, and therefore, the second inclined surface 36 is provided correspondingly only on one side in the width direction X3. With respect to the insertion holes 34 arranged at positions other than the both end sides in the width direction X3, the insertion holes 34 are arranged adjacently on both sides in the width direction X3, and therefore, the second inclined surface 36 is provided correspondingly on both sides in the width direction X3. The second inclined surface 36 is provided in a manner continuous with the insertion holes 34. Furthermore, between adjacent insertion holes 34 , second inclined surfaces 36 that are continuous with the adjacent insertion holes 34 are arranged side by side in the width direction X3 .

The smaller angle θ1 of the angles formed by the direction in which the first inclined surface 35 is inclined relative to the height direction X2 and the width direction X3 constitutes the inclination angle of the first inclined surface 35 that tapers toward the height direction X2 at both end sides of the width direction X3 on the inner side of the guide portion 31. Furthermore, the smaller angle θ2 of the angles formed by the direction in which the second inclined surface 36 is inclined relative to the height direction X2 and the width direction X3 constitutes the inclination angle of the second inclined surface 36 that tapers toward the entrance of the insertion hole 34 between adjacent insertion holes 34. The inclination angle of the first inclined surface 35, namely the angle θ1, is set to be larger than the inclination angle of the second inclined surface 36, namely the angle θ2.

Furthermore, the smaller angle θ4 of the angles formed by the direction in which the fourth inclined surface 53 is inclined relative to the height direction X2 and the front-back direction X4 constitutes the inclination angle of the fourth inclined surface 53 that tapers toward the entrance of the insertion hole 34 between adjacent insertion holes 34 in the front-back direction X4. The inclination angle of the third inclined surface 37, namely the angle θ3, is set to be larger than the inclination angle of the fourth inclined surface 53, namely the angle θ4.

[0175] Here, the operation when the plurality of needle-shaped counterpart connection components 101a arranged in two rows in the counterpart connector 101 are inserted into the electric connector 2 for connection is further described. When the plurality of counterpart connection components 101a are inserted into the electric connector 2, the plurality of counterpart connection components 101a are inserted into the movable housing 52 of the electric connector 2. At this time, the plurality of counterpart connection components 101a are sometimes inserted in a state where the insertion positions are offset relative to the movable housing 52.

When the plurality of counterpart-side connection components 101a are inserted with respect to the movable housing 52 in a state where the insertion positions are offset in the width direction X3, the plurality of counterpart-side connection components 101a are inserted into the opening 33 at positions offset in the width direction X3 with respect to the plurality of insertion holes 34 without overlapping in the insertion direction X1. When the plurality of counterpart-side connection components 101a inserted into the opening 33 of the guide portion 31 are inserted into the opening 33 in a state where the insertion positions are offset in the width direction X3, the front end portion of the counterpart-side connection component 101a on one of the two end sides in the width direction X3 of the plurality of counterpart-side connection components 101a arranged in two rows abuts against the first inclined surface 35 on one of the two end sides in the width direction X3 of the inner wall of the guide portion 31. Furthermore, the dimension H1 of the first inclined surface 35 in the height direction X2 is set to be larger than the dimension H2 of the second inclined surface 36 in the height direction X2, and the dimension W1 of the first inclined surface 35 in the width direction X3 is set to be larger than the dimension W2 of the second inclined surface 36 in the width direction X3. Therefore, when the plurality of counterpart connection members 101a arranged in two rows are inserted into the opening 33 of the guide portion 31 in a state of being staggered in the width direction X3, before the distal ends of the plurality of counterpart connection members 101a abut against the second inclined surfaces 36 reaching the plurality of insertion holes 34, the distal ends of the plurality of counterpart connection members 101a on one side of the two end sides in the width direction X3 of the plurality of counterpart connection members 101a abut against the first inclined surface 35 on one side of the two end sides in the width direction X3 of the inner wall of the guide portion 31.

In addition, Fig.31 is a diagram showing a plurality of object-side connecting components 101a from Fig.30 The state shown is further inserted into the inner side of the guide portion 31. Fig.32 is a diagram showing a plurality of object-side connecting components 101a from Fig.31 The state shown is a state further inserted into the inner side of the guide portion 31. Fig.31, when the multiple object side connecting components 101a arranged in two rows are inserted into the opening 33 and the object side connecting components 101a on one side of the two end sides in the width direction X3 abut against the first inclined surface 35, the object side connecting components 101a on one side of the two end sides in the width direction X3 are inserted into the inner side of the opening 33 while sliding along the first inclined surface 35. As a result, the multiple object side connecting components 101a arranged in two rows move in the insertion direction X1 together with the object side connecting components 101a on one side of the two end sides in the width direction X3 of the opening 33 while sliding along the first inclined surface 35. Therefore, the multiple object side connecting components 101a arranged in two rows are guided by the first inclined surface 35 to be inserted into the inner side of the guide portion 31. And, as Fig.32 As shown, when the plurality of counterpart side connection members 101a are guided by the first inclined surface 35 and inserted into the inner side of the guide portion 31, they are then respectively guided to the plurality of insertion holes 34. When the plurality of counterpart side connection members 101a are respectively guided to the plurality of insertion holes 34, they are directly inserted into the plurality of insertion holes 34. And, the plurality of counterpart side connection members 101a respectively inserted into the plurality of insertion holes 34 respectively pass through the plurality of insertion holes 34, and contact the spring contact portion 40b of the counterpart side connection portion 40 of the terminal 13 held inside the movable housing 12, thereby being electrically connected to the terminal 13.

[0178] Next, a description will be given of a case where a plurality of counterpart-side connecting members 101 a arranged in two rows are inserted into the movable housing 52 in a state where the insertion positions are shifted in the front-rear direction X4 . Fig.33 It is a front view showing a state immediately before a plurality of needle-shaped mating connection members 101 a of the mating connector 101 are inserted into the electric connector 2 , and shows the electric connector 2 with the fixing housing 51 omitted. Fig.34 yes Fig.33 A cross-sectional view taken along the arrow direction at the HH line. Fig.33 and Fig.34 The figure shows a state where the plurality of counterpart-side connecting members 101 a arranged in two rows are inserted into the movable housing 52 in a state where the insertion positions are shifted in the front-rear direction X4 .

[0179] Reference Fig.33 and Fig.34When the plurality of counterpart-side connection components 101a are inserted into the movable housing 52, the plurality of counterpart-side connection components 101a are inserted into the opening 33 of the guide portion 31 of the movable housing 52. When the plurality of counterpart-side connection components 101a are inserted with respect to the movable housing 12 in a state where the insertion positions are offset in the front-rear direction X4, the plurality of counterpart-side connection components 101a are inserted into the opening 33 at positions offset in the front-rear direction X4 with respect to the plurality of insertion holes 34 without overlapping in the insertion direction X1. When the plurality of counterpart-side connection components 101a inserted into the opening 33 of the guide portion 31 in a state where the insertion positions are offset in the front-rear direction X4, the distal end portions of the counterpart-side connection components 101a arranged in two rows on one side of the row in the front-rear direction X4 abut against the third inclined surface 37 on one side of the two end sides of the inner wall of the guide portion 31 in the front-rear direction X4. Furthermore, the dimension H3 of the third inclined surface 37 in the height direction X2 is set to be larger than the dimension H4 of the fourth inclined surface 53 in the height direction X2, and the dimension Y3 of the third inclined surface 37 in the front-rear direction X4 is set to be larger than the dimension Y4 of the fourth inclined surface 53 in the front-rear direction X4. Therefore, when the plurality of counterpart-side connection members 101a arranged in two rows are inserted into the opening 33 of the guide portion 31 in a state of being staggered in the front-rear direction X4, before the distal ends of the plurality of counterpart-side connection members 101a reach the same height as the fourth inclined surface 53 of each of the plurality of insertion holes 34, the distal ends of the counterpart-side connection members 101a arranged in the row on one side in the front-rear direction X4 abut against the third inclined surface 37 on one side of the two end sides in the front-rear direction X4 of the inner wall of the guide portion 31.

[0180] Fig.35 1 is a cross-sectional view showing a state in which a plurality of needle-shaped counterpart connection members 101a of the counterpart connector 101 are halfway inserted into the electric connector 2. Fig.33 The cross-sectional view at the position corresponding to the HH line position. Fig.35When the plurality of counterpart connection components 101a are inserted into the opening 33 and the counterpart connection components 101a arranged in two rows on one side of the front-back direction X4 come into contact with the third inclined surface 37 on one side of the two end sides in the front-back direction X4, the counterpart connection components 101a arranged in one side of the front-back direction X4 are inserted into the inner side of the opening 33 while sliding along the third inclined surface 37. Thus, the plurality of counterpart connection components 101a arranged in two rows move in the insertion direction X1 together with the counterpart connection components 101a arranged in one side of the front-back direction X4 inserted into the opening 33 while sliding along the third inclined surface 37. Therefore, the plurality of counterpart connection components 101a arranged in two rows are guided by the third inclined surface 37 and inserted into the inner side of the guide portion 31. And, when the plurality of counterpart connection components 101a are guided by the third inclined surface 37 and inserted into the inner side of the guide portion 31, they are then guided to the plurality of insertion holes 34 respectively. When the plurality of counterpart connection members 101a are respectively guided to the plurality of insertion holes 34, they are directly inserted into the plurality of insertion holes 34. Furthermore, the plurality of counterpart connection members 101a respectively inserted into the plurality of insertion holes 34 respectively pass through the plurality of insertion holes 34, and contact the spring contact portion 40b of the counterpart connection portion 40 of the terminal 13 held inside the movable housing 52, thereby being electrically connected to the terminal 13.

[0181] According to the second embodiment described above, when the plurality of needle-shaped counterpart connection members 101a arranged in two rows are connected to the electric connector 2, the plurality of counterpart connection members 101a are inserted into the opening 33 of the guide portion 31 of the movable housing 52. The plurality of counterpart connection members 101a inserted into the opening 33 of the guide portion 31 of the movable housing 52 are inserted into the opening 33 in a state where the insertion positions are not misaligned, and are respectively inserted into the plurality of insertion holes 34 on the inner side of the guide portion 31. And the plurality of counterpart connection members 101a respectively inserted into the plurality of insertion holes 34 are respectively electrically connected to the plurality of terminals 13. On the other hand, when the plurality of counterpart connection members 101a inserted into the opening 33 of the guide portion 31 of the movable housing 52 are inserted into the opening 33 in a state where the insertion positions are shifted in the width direction X3, the distal end portions of the counterpart connection members 101a on one side of the two end sides in the width direction X3 of the plurality of counterpart connection members 101a arranged in two rows abut against the first inclined surface 35 on one side of the two end sides in the width direction X3 of the inner wall of the guide portion 31. In addition, regarding the first inclined surface 35 provided on the side surfaces on both ends in the width direction X3 of the inner wall of the guide portion 31 and inclined toward the height direction X2 and toward the outside in the width direction X3, the first inclined surface 35 is set to have a larger dimension in the height direction X2 and a larger dimension in the width direction X3 than the second inclined surface 36 inclined toward the entrance of the insertion hole 34 between the adjacent insertion holes 34 in the width direction X3. Therefore, when the plurality of counterpart connection members 101a arranged in two rows are inserted into the opening 33 of the guide portion 31 in a state where they are staggered in the width direction X3, before the distal ends of the plurality of counterpart connection members 101a abut against the second inclined surfaces 36 that reach the plurality of insertion holes 34, the distal ends of the counterpart connection members 101a on one side of the two end sides in the width direction X3 of the plurality of counterpart connection members 101a abut against the first inclined surfaces 35 on one side of the two end sides in the width direction X3 of the inner wall of the guide portion 31. Then, the counterpart connection member 101a on one side of the two end sides in the width direction X3 is inserted into the inside of the opening 33 while sliding along the first inclined surfaces 35. Thus, the plurality of counterpart connection members 101a arranged in two rows move together with the counterpart connection member 101a on one side of the two end sides in the width direction X3 of the opening 33 while sliding along the first inclined surfaces 35, and are inserted into the inside of the guide portion 31 guided by the first inclined surfaces 35. The plurality of counterpart connection members 101 a are inserted into the inner side of the guide portion 31 while being guided along the inclination direction of the first inclined surface 35 , and then are respectively inserted into the plurality of insertion holes 34 .Therefore, even when a plurality of counterpart connection members 101a are inserted into the movable housing 52 in a state where the insertion positions are offset in the width direction X3, the plurality of counterpart connection members 101a are inserted into the inner side of the guide portion 31 while being guided along the inclination direction of the first inclined surface 35, and are properly inserted into the plurality of insertion holes 34. Therefore, the operation of inserting the plurality of needle-shaped counterpart connection members 101a arranged in two rows into the electric connector 2 for connection can be properly and easily performed. In addition, according to the second embodiment, in the movable housing 52, the operation of inserting the plurality of needle-shaped counterpart connection members 101a arranged in two rows into the electric connector 2 for connection can be properly and easily performed with a simple structure in which the first inclined surface 35 is provided on both end sides in the width direction X3 of the guide portion 31 provided with the opening 33. Therefore, it is possible to suppress the enlargement and complication of the structure of the electric connector 2 and the counterpart connector 101 connected to the electric connector 2.

[0182] As described above, according to the second embodiment, it is possible to provide an electric connector 2 that can appropriately and easily perform the operation of inserting a plurality of needle-shaped counterpart connection members arranged in two rows for connection, while suppressing increase in size and complexity of the structure.

[0183] In addition, when the size of the smaller angle θ1 of the angles formed by the direction in which the first inclined surface 35 is inclined with respect to the height direction X2 and the width direction X3 is equal to the size of the smaller angle θ2 of the angles formed by the direction in which the second inclined surface 36 is inclined with respect to the height direction X2 and the width direction X3, when the plurality of counterpart-side connecting members 101a are inserted into the inner side of the guide portion 31 while being guided along the inclination direction of the first inclined surface 35 and reaching the same height position as the second inclined surface 36, they are then guided along the first inclined surface 35 and the second inclined surface 36 and inserted into the plurality of insertion holes 34. In contrast, according to the second embodiment, the size of the smaller angle θ1 of the angles formed by the direction in which the first inclined surface 35 is inclined with respect to the height direction X2 and the width direction X3 is set to be larger than the size of the smaller angle θ2 of the angles formed by the direction in which the second inclined surface 36 is inclined with respect to the height direction X2 and the width direction X3. Thus, even if the plurality of counterpart connection members 101a are guided along the inclination direction of the first inclined surface 35 and inserted into the inner side of the guide portion 31 and reach the same height position as the second inclined surface 36, they hardly come into sliding contact with the second inclined surface 36, but continue to be guided along the first inclined surface 35 and are respectively inserted into the plurality of insertion holes 34. In this way, the plurality of counterpart connection members 101a inserted into the opening 33 of the movable housing 52 hardly come into sliding contact with the second inclined surface 36, but are guided along the first inclined surface 35 and are respectively inserted into the plurality of insertion holes 34. Therefore, the operation of properly inserting and connecting the plurality of needle-shaped counterpart connection members 101a arranged in two rows can be performed more smoothly and easily.

[0184] According to the second embodiment, when the plurality of needle-shaped counterpart connection members 101a arranged in two rows are inserted into the opening 33 of the guide portion 31 of the movable housing 52 in a state where the insertion positions are shifted in the front-rear direction X4, the distal end portions of the counterpart connection members 101a arranged in one row in the front-rear direction X4 among the plurality of counterpart connection members 101a arranged in two rows abut against the third inclined surface 37 on one side of the two end sides in the front-rear direction X4 of the inner wall of the guide portion 31. In addition, regarding the third inclined surface 37 provided on the two end side surfaces in the front-rear direction X4 of the inner wall of the guide portion 31 and inclined toward the height direction X2 and toward the outer side in the front-rear direction X4, the third inclined surface 37 is set to have a larger dimension in the height direction X2 and a larger dimension in the front-rear direction X4 than the fourth inclined surface 53 inclined toward the entrance of the insertion hole 34 between the adjacent insertion holes 34 in the front-rear direction X4. Therefore, when the plurality of counterpart connection members 101a arranged in two rows are inserted into the opening 33 of the guide portion 31 in a state of being staggered in the front-rear direction X4, the distal ends of the counterpart connection members 101a arranged in the row on one side in the front-rear direction X4 come into contact with the third inclined surface 37 on one side of both ends in the front-rear direction X4 of the inner wall of the guide portion 31 before the distal ends of the plurality of counterpart connection members 101a come into contact with the fourth inclined surface 53 reaching each side of the plurality of insertion holes 34. Then, the plurality of counterpart connection members 101a are inserted into the inner side of the opening 33 while sliding along the third inclined surface 37. Thus, the plurality of counterpart connection members 101a arranged in two rows move together with the counterpart connection members 101a arranged in the row on one side in the front-rear direction X4 which are inserted into the opening 33 while sliding along the third inclined surface 37, and are inserted into the inner side of the guide portion 31 while being guided by the third inclined surface 37. The plurality of counterpart-side connection components 101a are inserted into the inner side of the guide portion 31 while being guided along the inclination direction of the third inclination surface 37, and then are respectively inserted into the plurality of insertion holes 34. Therefore, even when the plurality of counterpart-side connection components 101a are inserted into the movable housing 52 in a state where the insertion positions are offset in the front-rear direction X4, the plurality of counterpart-side connection components 101a are inserted into the inner side of the guide portion 31 while being guided along the inclination direction of the third inclination surface 37, and are appropriately inserted into the plurality of insertion holes 34. Therefore, the operation of inserting the plurality of needle-shaped counterpart-side connection components 101a arranged in two rows into the electric connector 2 for connection can be appropriately and easily performed.

[0185] In addition, when the size of the smaller angle θ3 among the angles formed by the direction in which the third inclined surface 37 is inclined with respect to the height direction X2 and the front-rear direction X4 is equal to the size of the smaller angle θ4 among the angles formed by the direction in which the fourth inclined surface 53 is inclined with respect to the height direction X2 and the front-rear direction X4, when the plurality of counterpart-side connecting members 101a are inserted into the inner side of the guide portion 31 while being guided along the inclination direction of the third inclined surface 37 and reaching the same height position as the fourth inclined surface 53, they are then guided along the third inclined surface 37 and the fourth inclined surface 53 and inserted into the plurality of insertion holes 34. In contrast, according to the second embodiment, the size of the smaller angle θ3 among the angles formed by the direction in which the third inclined surface 37 is inclined with respect to the height direction X2 and the front-rear direction X4 is set to be larger than the size of the smaller angle θ4 among the angles formed by the direction in which the fourth inclined surface 53 is inclined with respect to the height direction X2 and the front-rear direction X4. Thus, even if the plurality of counterpart connection members 101a are guided along the inclination direction of the third inclined surface 37 and inserted into the inner side of the guide portion 31 and reach the same height position as the fourth inclined surface 53, they hardly come into sliding contact with the fourth inclined surface 53, but continue to be guided along the third inclined surface 37 and are respectively inserted into the plurality of insertion holes 34. In this way, the plurality of counterpart connection members 101a inserted into the opening 33 of the movable housing 52 hardly come into sliding contact with the fourth inclined surface 53, but are guided along the third inclined surface 37 and are respectively inserted into the plurality of insertion holes 34. Therefore, the operation of properly inserting and connecting the plurality of needle-shaped counterpart connection members 101a arranged in two rows can be performed more smoothly and easily.
