Description

Background Technology

[0001] Patent Document 1 discloses a connector comprising a housing and a spear-shaped portion. The housing has a cavity into which a terminal part can be inserted from the rear. The spear-shaped portion is formed in a cantilevered shape protruding forward. During the insertion of the terminal part into the cavity, the spear-shaped portion abuts against the terminal part and flexes and deforms, and when the terminal part is properly inserted into the cavity, it shifts in the return direction, holding the terminal part in place to prevent it from falling off from the rear.

[0002] In this structure, when a rearward pulling force is applied to the terminal part, if the spear-shaped portion flexes in the direction opposite to the direction of flexing deformation during the insertion of the terminal part, the spear-shaped portion may be bent, reducing the force restricting the rearward movement of the terminal part. Therefore, Patent Document 1 employs the following structure: A limiting portion protruding from both sides of the inner wall of the cavity is formed, and abutment portions are formed extending from both sides of the spear-shaped portion. Furthermore, when the spear-shaped portion is about to flex in the aforementioned opposite direction, the abutment portions of the spear-shaped portion abut against the limiting portions, thus restricting further flexing of the spear-shaped portion. Therefore, according to the above structure, bending of the spear-shaped portion is less likely to occur, and the reduction in the force restricting the rearward movement of the terminal part can be suppressed.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2012-216344 Summary of the Invention

[0006] The problem that the invention aims to solve

[0007] However, in the technology of Patent Document 1, the flexural movement of the spear-shaped portion is restricted by a pair of limiting portions protruding from both sides of the inner wall of the cavity, thus locally reducing the width dimension of the spear-shaped portion. As a result, the strength (locking force) of the spear-shaped portion is reduced.

[0008] Therefore, this disclosure improves the technology that can suppress the reduction in strength of the spear-shaped portion.

[0009] Solution for solving the problem

[0010] The connector disclosed herein includes a terminal component and a housing. The housing has: a cavity extending in a front-rear direction; a spear-shaped portion formed on one side of the cavity in a height direction, capable of flexing and deforming in the height direction; and an extension surface formed on the outer side of the cavity in a width direction, facing the one side in the height direction. The terminal component has a terminal body disposed within the cavity. The terminal body has a locking portion on the one side in the height direction. The spear-shaped portion has: a limiting portion protruding from the one side in the height direction into the cavity, capable of locking from the rear relative to the locking portion; and a protruding portion extending from the limiting portion in the width direction toward the side where the extension surface is located. The protruding portion has an opposing surface opposite to the extension surface from the one side in the height direction.

[0026] [Description of embodiments of this disclosure]

[0027] First, the implementation methods of this disclosure are listed and explained.

[0028] The connector disclosed herein,

[0029] (1) A terminal component and a housing, the housing having: a cavity extending in a front-rear direction; a spear-shaped portion formed on one side of the cavity in the height direction, capable of flexing and deforming in the height direction; and an extension surface formed on the outer side of the cavity in the width direction, facing the one side in the height direction, the terminal component having a terminal body disposed within the cavity, the terminal body having a locking portion on the one side in the height direction, the spear-shaped portion having: a limiting portion protruding from the one side in the height direction into the cavity, capable of locking from the rear relative to the locking portion; and a protruding portion extending from the limiting portion in the width direction toward the side where the extension surface is located, the protruding portion having an opposing surface opposite to the extension surface from the one side in the height direction.

[0030] In the aforementioned connector, when a rearward force is applied to the terminal part disposed within the cavity, the limiting portion locks against the locking portion of the terminal part from the rear. At this time, even if the spear-shaped portion is pressed down by the locking portion and flexes and deforms to the other side in the height direction (terminal part side), further flexing deformation is limited by the contact between the opposing surface and the extending surface of the spear-shaped portion. Furthermore, the opposing surface and the extending surface are disposed on the outer side in the width direction of the cavity. Therefore, it is not necessary to reduce the width dimension of the spear-shaped portion, thus suppressing a decrease in the strength (locking force) of the spear-shaped portion.

[0031] (2) Alternatively, the housing may have: a front wall disposed at the front end of the housing; and a demolding hole for the spear-shaped portion, defined by the end edge of one side of the front wall in the height direction, through which the spear-shaped portion can be visually confirmed from the front, and the front wall having a circumferentially closed tab insertion hole at a position communicating with the cavity.

[0032] In existing connectors, the ejector hole of the spear-shaped portion is formed in communication with the tab insertion hole. In this structure, a portion of the circumferential direction of the tab insertion hole is missing; therefore, a front member with a fully circumferentially closed tab insertion hole is usually installed separately. However, in the structure with an additional front member, the number of components increases. In this regard, the above-described connector can suppress the spear-shaped portion from protruding into the cavity side by increasing the force that restricts the rearward movement of the terminal parts. The ejector hole of the spear-shaped portion can be defined by the end edge on one side in the height direction of the front wall, and the tab insertion hole is formed into a fully circumferentially closed shape. Therefore, the above-described connector does not need to provide an additional front member, and can suppress the increase in the number of components.

[0033] (3) Alternatively, the extending surface may be formed only on one side of the cavity in the width direction, and the protrusion may extend from the limiting portion only to the side of the extending surface in the width direction.

[0034] Because the aforementioned connector has its extension surface and protrusion only located on one side of the width direction, it can suppress the enlargement of the housing in the width direction compared to a structure where the extension surface and protrusion are located on both sides.

[0035] (4) Alternatively, the limiting part may have a limiting surface facing forward and a recessed part that is recessed backward from the limiting surface on one side in the width direction, and the locking part may be able to be inserted into the recessed part on one side in the width direction when in contact with the limiting surface.

[0036] In the aforementioned structure where the protrusion is only located on one side of the width direction, when the spear-shaped portion shifts to the other side, the contact area between the opposing surface and the extending surface decreases, and the force restricting the flexural deformation of the spear-shaped portion decreases. In this regard, when a rearward force acts on the terminal part causing the restricting surface of the spear-shaped portion to contact the locking part, the connector, by having the end of the locking part on one side of the width direction embedded in the recess, causes the front end of the terminal part to swing towards one side of the width direction. In this state, when a further rearward force acts on the terminal part, the spear-shaped portion is pulled closer towards one side of the width direction. Therefore, the connector can suppress the shift of the spear-shaped portion towards the other side of the width direction and can suppress the decrease in the force restricting the flexural deformation of the spear-shaped portion.

[0037] (5) Alternatively, the spear-shaped portion may have a second opposing surface, which intersects with the opposing surface and faces one side in the width direction. The second opposing surface is disposed opposite to the inner surface of one side in the width direction in the cavity when the opposing surface is in contact with the extension surface.

[0038] According to the connector described above, even if the spear-shaped portion flexes and deforms in one direction in the width direction when the opposing surface of the spear-shaped portion is in contact with the extending surface, further flexing and deformation is limited by the contact between the second opposing surface and the inner surface of the cavity in the width direction. Therefore, the connector described above can stabilize the position of the spear-shaped portion in the width direction, resulting in more stable restriction of the rearward movement of the terminal parts.

[0039] [Details of the embodiments of this disclosure]

[0040] Specific examples of this disclosure are described below with reference to the accompanying drawings. Furthermore, the invention is not limited to these examples, but rather, as shown by the claims, includes all modifications within the meaning and scope of the claims.

[0041] [Implementation Method 1]

[0042] Figure 1 The connector 10 of Embodiment 1 is disclosed. The connector 10 engages with a counterpart connector (not shown). In the following description, the direction in which the connector 10 engages with the counterpart connector is defined as the front of the connector 10, and the opposite direction is defined as the rear of the connector 10. Figures 3 to 10 The vertical direction is defined as the vertical direction of connector 10. The horizontal direction when viewing connector 10 from the front is defined as the horizontal direction of connector 10. Furthermore, in this embodiment, "bottom" corresponds to "one side in the height direction", "top" corresponds to "the other side in the height direction", "right" corresponds to "one side in the width direction", and "left" corresponds to "the other side in the width direction".

[0043] <Structure of Connector 10>

[0044] like Figure 1 As shown, connector 10 includes terminal parts 20 and housing 50.

[0045] Terminal component 20 has multiple terminals (nine in this embodiment). Figure 1 and Figure 7 In this text, six terminals are omitted, and only three are described. Terminal part 20 is female and conductive. Terminal part 20 is formed by bending a metal plate. (Example...) Figure 2 and Figure 3 As shown, the terminal part 20 has a terminal body 21 and a wire connection part 22.

[0046] like Figure 2 and Figure 3 As shown, the terminal body 21 is formed to extend in the front-rear direction. The terminal body 21 has a cylindrical portion 23, an elastic contact portion 24, a locking portion 25, and protrusions 26 and 27 to prevent accidental insertion.

[0047] like Figure 2 and Figure 3 As shown, the cylindrical portion 23 is formed into a cylindrical shape (more specifically a square cylindrical shape) extending in the front-rear direction, with openings on both the front and rear sides.

[0048] like Figure 3 As shown, the elastic contact portion 24 is disposed inside the cylindrical portion 23. Figure 1 As shown, the front end of the elastic contact portion 24 is connected to the plate portion constituting the lower side of the cylindrical portion 23, and the elastic contact portion 24 is formed in a cantilevered shape extending rearward. When the connector 10 is engaged with the counterpart connector (not shown), the elastic contact portion 24 is electrically connected to the counterpart terminal part (not shown).

[0049] like Figures 2-4 As shown, a locking portion 25 is provided on the lower end side of the terminal body 21. The locking portion 25 is formed to protrude downward from the lower surface of the cylindrical portion 23. The locking portion 25 has a first protrusion 31, a second protrusion 32, and a connecting portion 33. The first protrusion 31 and the second protrusion 32 are each formed to protrude downward from the lower surface of the terminal body 21. The first protrusion 31 and the second protrusion 32 are arranged spaced apart from each other in the left-right direction. The first protrusion 31 is located to the right of the second protrusion 32. The first protrusion 31 is provided at the right end of the locking portion 25, and the second protrusion 32 is provided at the left end of the locking portion 25. The second protrusion 32 has a second rear surface portion 32A that slopes downward in the rearward direction. The first protrusion 31 has a first rear surface portion 31A, which slopes downward in the rearward direction at a steeper angle than the second rear surface portion 32A. The second rear surface portion 32A is positioned forward of the first rear surface portion 31A. The connecting portion 33 connects the lower ends of the first protrusion 31 and the second protrusion 32 to each other.

[0050] like Figure 3 As shown, the anti-misinsertion protrusions 26 and 27 are positioned rearward of the locking portion 25. The anti-misinsertion protrusion 26 is formed to protrude downward from the lower surface of the cylindrical portion 23. The anti-misinsertion protrusion 27 is formed to protrude upward from the upper surface of the cylindrical portion 23. When the terminal part 20 is inserted into the cavity 51 in both vertical and horizontal directions, the anti-misinsertion protrusions 26 and 27 contact the step within the cavity 51, thus restricting the insertion of the terminal part 20.

[0051] like Figure 3As shown, the wire connection portion 22 is positioned rearward of the anti-misinsertion protrusions 26 and 27. The wire connection portion 22 is electrically connected to the conductor 81 of the wire 80 by crimping or the like.

[0052] The housing 50 is made of synthetic resin and has insulating properties. For example... Figure 3 As shown, the housing 50 has a cavity 51 and a spear-shaped portion 52. The cavity 51 is formed to extend in the front-rear direction. The cavity 51 opens at the rear of the housing 50, allowing the terminal part 20 to be inserted from the rear.

[0053] Multiple cavities 51 are arranged in the left-right and up-down directions. For example... Figure 4 and Figure 5 As shown, the inner wall surface of cavity 51 has a spear-shaped opposing surface 53, a first side surface 54, and a second side surface 55. The spear-shaped opposing surface 53 faces the spear-shaped portion 52 from above. The cylindrical portion 23 of terminal part 20 is disposed between the spear-shaped portion 52 and the spear-shaped opposing surface 53.

[0054] like Figure 5 As shown, the first side surface 54 and the second side surface 55 are opposite each other in the left-right direction. The first side surface 54 forms the inner wall surface of the right side of the cavity 51, facing to the left. The second side surface 55 forms the inner wall surface of the left side of the cavity 51, facing to the right. The terminal body 21 (more specifically, the cylindrical portion 23) of the terminal part 20 is disposed between the first side surface 54 and the second side surface 55. The upper ends of the first side surface 54 and the second side surface 55 are connected to each other by a spear-shaped opposing surface 53. The lower ends of the first side surface 54 and the second side surface 55 form an opening 56 that opens downward. Furthermore, the first side surface 54 corresponds to an example of "the inner surface of one side in the width direction of the cavity 51".

[0055] like Figure 4 and Figure 5 As shown, the housing 50 has an extending surface 57. The extending surface 57 is formed on the outer side of the cavity 51 in the left-right direction. That is, the extending surface 57 is formed on the right side of the first side surface 54. The extending surface 57 is arranged facing downwards. The extending surface 57 intersects the first side surface 54. The left end of the extending surface 57 is connected to the lower end of the first side surface 54.

[0056] like Figure 3 As shown, the spear-shaped portion 52 is disposed at the lower end of the cavity 51 and can flex and deform in the vertical direction. The spear-shaped portion 52 is formed into a cantilevered shape extending forward. The spear-shaped portion 52 protrudes into the cavity 51. Figure 4 As shown, the spear-shaped portion 52 has a limiting portion 60 and a protruding portion 61.

[0057] like Figure 3 As shown, the limiting part 60 protrudes from below into the cavity 51, and can be locked from the rear relative to the locking part 25. Figure 4As shown, the limiting part 60 is disposed between the first side surface 54 and the second side surface 55 in the left-right direction. Figure 3 As shown, the limiting part 60 is disposed behind the locking part 25 of the terminal part 20 disposed within the cavity 51. The limiting part 60 restricts the rearward movement of the terminal part 20 by contacting the locking part 25 of the rearward-moving terminal part 20. Figure 8 and Figure 11 As shown, the limiting part 60 has a limiting surface 62 and a recess 63.

[0058] The limiting surface 62 extends from the center of the limiting portion 60 to its left end in the left-right direction. The limiting surface 62 has a first surface 62A facing forward, a second surface 62B that slopes downward in the rearward direction from the lower end of the first surface 62A, and a corner portion 62C formed by the first surface 62A and the second surface 62B. The first surface 62A faces the second rear surface portion 32A of the locking portion 25 from the rear.

[0059] The recess 63 is formed in a shape that is recessed rearward from the limiting surface 62 at the right end of the limiting portion 60. The recess 63 is formed in a stepped shape relative to the limiting surface 62 on the right side. Figure 8 As shown, the bottom surface 63A of the recess 63 is opposite to the first rear surface portion 31A of the locking portion 25 from the rear.

[0060] like Figure 5 As shown, the protrusion 61 extends to the right from the limiting portion 60, extending to the right of the first side surface 54. The protrusion 61 has a first opposing surface 64 that is vertically opposed to the extending surface 57. The first opposing surface 64 is an example of an "opposing surface". The first opposing surface 64 can contact the extending surface 57 when the spear-shaped portion 52 flexes and deforms upward. When the first opposing surface 64 contacts the extending surface 57, it can limit the further upward flexing and deformation of the spear-shaped portion 52. The protrusion 61 is only provided on the right side of the limiting portion 60. That is, in the left-right direction, the center of the spear-shaped portion 52 is offset to the right relative to the center of the cavity 51.

[0061] like Figure 5 As shown, the spear-shaped portion 52 has a second opposing surface 65. The second opposing surface 65 faces to the right. The second opposing surface 65 intersects with the first opposing surface 64. The lower end of the second opposing surface 65 is connected to the left end of the first opposing surface 64. Figure 6 As shown, the second opposing surface 65 is positioned opposite the first side surface 54 in the left-right direction while the first opposing surface 64 is in contact with the extension surface 57. Even if the spear-shaped portion 52 flexes and deforms to the right, further flexing and deformation is restricted by the contact between the second opposing surface 65 and the first side surface 54.

[0062] like Figure 3 and Figure 7As shown, the housing 50 has a front wall 70, a tab insertion hole 71, a demolding hole 72 for the spear-shaped portion 52, and a partition wall 73. The front wall 70 is disposed at the front end of the housing 50. The front wall 70 is disposed in front of the cavity 51, restricting the forward movement of the terminal part 20 disposed in the cavity 51. The tab insertion hole 71 extends through the front wall 70 in the front-rear direction and communicates with the cavity 51. The tab insertion hole 71 is formed in a fully closed shape. The tab insertion hole 71 has a tapered surface 74 that expands forward. The tapered surface 74 is formed all around the circumference of the tab insertion hole 71. The demolding hole 72 for the spear-shaped portion 52 is disposed below the tab insertion hole 71. The demolding hole 72 for the spear-shaped portion 52 is defined by the lower edge of the front wall 70. The demolding hole 72 for the spear-shaped portion 52 is a hole formed when the mold forming the spear-shaped portion 52 is pulled out. The spear-shaped portion 52 can be visually identified from the front through the demolding hole 72. The partition wall 73 is a wall that separates the tab insertion hole 71 from the demolding hole 72 of the spear-shaped portion 52.

[0063] <Function and Effect of Connector 10>

[0064] Terminal part 20 is inserted from the rear into cavity 51 of housing 50. During insertion into cavity 51, the spear-shaped portion 52 is pressed down and deformed downwards by the terminal part 20. When the terminal part 20 reaches its proper insertion position, the spear-shaped portion 52 returns to its original shape through its own elastic force. Thus, as... Figure 8 and Figure 11 As shown, the terminal part 20 is disposed in the cavity 51, and the limiting part 60 of the spear-shaped part 52 is disposed behind the locking part 25 of the terminal part 20.

[0065] With the terminal part 20 disposed within the cavity 51, when the wire 80 connected to the terminal part 20 is pulled rearward, a rearward force acts on the terminal part 20. Furthermore, when the terminal part 20 moves rearward, as... Figure 9 and Figure 12 As shown, the locking portion 25 of the terminal part 20 contacts the spear-shaped portion 52. More specifically, the second rear surface portion 32A of the locking portion 25 contacts the corner portion 62C of the limiting portion 60. This restricts the rearward movement of the terminal part 20.

[0066] Furthermore, when a force is applied to the terminal part 20 from the rear, the spear-shaped portion 52 is pressed down by the locking portion 25 and flexes upward. And, as... Figure 10As shown, when the first opposing surface 64 of the spear-shaped portion 52 contacts the extending surface 57, further flexural deformation of the spear-shaped portion 52 can be limited. Furthermore, the first opposing surface 64 and the extending surface 57, which limit the upward flexural deformation of the spear-shaped portion 52, are positioned on the outer side of the cavity 51 in the left-right direction (more specifically, to the right of the first side surface 54). Therefore, it is not necessary to reduce the width of the spear-shaped portion 52, thus suppressing a decrease in the strength (locking force) of the spear-shaped portion 52. Therefore, the connector 10 can suppress a decrease in the strength (locking force) of the spear-shaped portion 52 and can suppress flexural deformation of the spear-shaped portion 52 that restricts the rearward movement of the terminal part 20.

[0067] Furthermore, since the extension 61 of the connector 10 is only provided on the right side, compared with the structure in which the extension 61 is provided on both sides, the enlargement of the housing 50 in the left-right direction can be suppressed.

[0068] However, in a structure where the protrusion 61 is only located on the right side, when the spear-shaped portion 52 shifts to the left, the contact area between the first opposing surface 64 and the extending surface 57 decreases, reducing the force restricting the flexural deformation of the spear-shaped portion 52. In this respect, when the connector 10 exerts a rearward force on the terminal part 20, causing the spear-shaped portion 52 to contact the locking portion 25, as... Figure 13 As shown, the right end of the locking portion 25 is inserted into the recess 63 of the spear-shaped portion 52, causing the front end of the terminal part 20 to swing to the right. In this state, when a rearward force is applied further to the terminal part 20, the spear-shaped portion 52 is pulled closer to the right. Therefore, the connector 10 can suppress the leftward displacement of the spear-shaped portion 52 and can suppress the reduction of the force limiting the flexural deformation of the spear-shaped portion 52.

[0069] However, in the above structure, the rightward bending deformation of the spear-shaped portion 52 may cause instability in its function of restricting the rearward movement of the terminal part 20. In this regard, the spear-shaped portion 52 has a second opposing surface 65 that faces the first side surface 54 in the left-right direction when the first opposing surface 64 is in contact with the extending surface 57. Therefore, even if the spear-shaped portion 52 bends to the right when the first opposing surface 64 is in contact with the extending surface 57, further bending deformation is restricted by the contact between the second opposing surface 65 and the first side surface 54. Therefore, the connector 10 can stabilize the left-right position of the spear-shaped portion 52, resulting in more stable restriction of the rearward movement of the terminal part 20.

[0070] With this structure, the force limiting the rearward movement of the terminal part 20 by the spear-shaped portion 52 is increased, and the protrusion of the spear-shaped portion 52 into the cavity 51 side is suppressed. Furthermore, the demolding hole 72 is defined by the lower edge of the front wall 70, and the tab insertion hole 71 is formed into a fully circumferentially closed shape. Therefore, according to the connector 10, it is not necessary to separately provide a front member with a fully circumferentially closed tab insertion hole, thus suppressing the increase in the number of parts.

[0071] [Other embodiments of this disclosure]

[0072] The embodiments disclosed herein should be considered illustrative in all respects, and not restrictive.

[0073] (1) In the above embodiment, the protrusion is a structure that is only provided on the right side of the limiting part, but it may also be a structure that is provided on both the left and right sides.

[0074] (2) In the above embodiment, a structure with partitions is provided, but a structure without partitions is also possible. That is, a structure in which the demolding hole of the spear-shaped part is connected to the through hole of the tab is also possible. In other words, the demolding hole of the spear-shaped part can also be configured as a demolding hole on both the spear-shaped part and the through hole of the tab.

[0075] (3) In the above embodiments, the spear-shaped part is a structure with a recess, but it can also be a structure without a recess.

[0076] (4) In the above embodiment, the spear-shaped portion has a structure having a second opposing surface that is opposite to the first side surface in the left-right direction, but it may also be a structure that does not have a second opposing surface. For example, the protruding portion may also be a structure that does not have a step between it and the limiting portion.

[0077] (5) In the above embodiment, the second opposing surface is a structure that intersects with the first opposing surface, but it can also be a structure that does not intersect. For example, a step can also be provided between the second opposing surface and the first opposing surface.
