Description

Technical Field

[0001] The present invention relates to a connector. Background Art

[0002] Patent Document 1 discloses a dielectric body that is formed by combining a holding member and a lid member in a direction intersecting the axial direction of a wire and can accommodate an inner conductor. An inducing portion is formed in the lid member. When the lid member and the holding member are combined, the inducing portion brings the holding member and the lid member closer to each other in the combining direction as the lid member is displaced from a temporarily assembled position in the front-rear direction to a properly assembled position. Thereby, the wobbling of the lid member and the holding member in the combining direction can be suppressed. Prior Art Documents Patent Document

[0003] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2018-147558 Summary of the Invention Problems to be Solved by the Invention

[0004] However, it can be assumed that a plurality of terminals are accommodated in a connector in upper and lower layers, and the upper and lower terminals are restricted in position by upper and lower lid members separated from each other.

[0005] In this case, the accumulation of dimensional tolerances of a plurality of components may affect the positional error of the upper and lower lid members. If the positional error of the upper and lower lid members becomes large, the relative positional deviation between the upper and lower layer terminals may become large.

[0006] Here, an object of the present invention is to reduce the relative positional deviation between different terminals. Solutions to the Problems

[0007] The connector of the present invention holds a first terminal and a second terminal, and the connector includes: a base member having a first setting recess in which the first terminal is provided; an internal member that overlaps the base member so as to close an opening on the opposite side of the bottom of the first setting recess and has a second setting recess in which the second terminal is provided; and a lid member that overlaps the internal member so as to close an opening on the opposite side of the bottom of the second setting recess. In a state where the internal member is sandwiched between the base member and the lid member, the lid member and the base member are combined in a contacting state. Advantages of the Invention

[0010] [Description of Embodiments of the Present Invention] First, embodiments of the present invention will be described by way of example.

[0011] The connector of the present invention is as follows.

[0012] (1) A connector that holds a first terminal and a second terminal, the connector comprising: a base member having a first setting recess in which the first terminal is disposed; an internal member that overlaps the base member so as to close an opening on the opposite side of the bottom of the first setting recess and has a second setting recess in which the second terminal is disposed; and a lid member that overlaps the internal member so as to close an opening on the opposite side of the bottom of the second setting recess, and in a state where the internal member is sandwiched between the base member and the lid member, the lid member and the base member are joined in contact with each other.

[0013] According to the present invention, in a state where the internal member is sandwiched between the base member and the lid member, the lid member and the base member are joined in contact with each other. Therefore, the first terminal in the first setting recess is positioned between the base member and the internal member positioned with reference to the base member. The second terminal in the second setting recess is positioned between the internal member positioned with reference to the base member and the lid member. Therefore, the accumulation of dimensional tolerances of multiple components is less likely to affect the relative positional relationship between the first terminal and the second terminal. Therefore, the relative positional deviation between different terminals can be reduced.

[0014] (2) In the connector of (1), it may be that the base member and the lid member surround the periphery of the internal member.

[0015] In this case, compared with the case where the outer shape of the connector is formed by combining three or more components, the outer shape error of the connector can be reduced.

[0016] (3) In the connector of (1) or (2), it may also be that the base member has a front wall, the front wall has an insertion guide hole, and the insertion guide hole guides the mating terminal connected to the first terminal and the second terminal.

[0017] In this case, by positioning the first terminal and the second terminal with reference to the base member having the insertion guide hole, the mating terminal can be smoothly connected to the first terminal and the second terminal.

[0018] (4) In any one of the connectors of (1) to (3), it may also be that the base member, the internal member, or the cover member has a flattened rib, the flattened rib protrudes in the direction of the combination of the base member, the internal member, and the cover member, and can be crushed in the combined state of the base member, the internal member, and the cover member.

[0019] In this case, by the flattened rib being crushed in the combined state of the base member, the internal member, and the cover member, the shaking between the components can be suppressed.

[0020] (5) In the connector of (4), it may also be that the base member or the cover member has a first flattened rib located at the contact portion between the base member and the cover member as the flattened rib, and the internal member or the cover member has a second flattened rib located at the contact portion between the internal member and the cover member as the flattened rib.

[0021] Thus, by the first flattened rib being crushed between the base member and the cover member, the shaking between the base member and the cover member can be suppressed. In addition, by the second flattened rib being crushed between the internal member and the cover member, the shaking between the internal member and the cover member can be suppressed. As a result, the shaking of the entire connector can be suppressed. Since the flattened rib can be prevented from being interposed between the base member and the internal member, the relative position error between the base member and the internal member can be reduced. As a result, the position error between the first terminal in the first setting recess of the base member and the second terminal in the second setting recess of the internal member can be reduced.

[0022] (6) In the connector of (4) or (5), it may also be that the flattened rib has a shape that gradually narrows from the base end side toward the tip end side.

[0023] Thus, the flattened rib can be gradually crushed from the tip end according to the gap between the components.

[0024] (7)In any one of the connectors in (4) to (6), it is also possible that the base member, the internal member, or the cover member has a front wall, the front wall has an insertion guide hole, the insertion guide hole guides the mating terminal connected to the first terminal and the second terminal, and the flattened rib is located near the edge on the front wall side rather than the edge far from the front wall in the base member, the internal member, or the cover member.

[0025] Thus, the shaking of each component can be suppressed near the insertion guide hole. Thus, near the insertion guide hole, the terminals are more correctly positioned, and it is easy to smoothly perform the connection operation of the mating terminal.

[0026] (8)In any one of the connectors in (1) to (7), it is also possible that the cover member has a cover body and a pair of locking walls, the cover body closes the opening on the opposite side of the bottom of the second setting recess, and the pair of locking walls extend from both sides of the cover body through the outer sides of both sides of the internal member toward both sides of the base member and are locked to both sides of the base member.

[0027] Thus, by locking the pair of locking walls to both sides of the base member, a structure in which the cover member is integrated with the base member in a state where the internal member is sandwiched between the base member and the cover member can be easily realized.

[0028] (9)In the connector in (8), it is also possible that sliding protrusions are formed on the inner surfaces of the pair of locking walls, and fitting guide grooves are formed on both sides of the base member, and the fitting guide grooves guide the sliding protrusions along the extending direction of the first terminal.

[0029] Thus, in a state where the internal member and the base member overlap, the cover member and the base member are integrated by moving the sliding protrusions along the fitting guide grooves, thereby assembling the connector.

[0030] (10)In the connector in (9), it is also possible that an interference surface is formed on the base member, the interference surface extends in a direction intersecting the extending direction of the fitting guide groove, and in a state where the internal member or the cover member floats relative to the base member, it interferes with the sliding protrusion to be moved.

[0031] Thus, assembly defects can be suppressed.

[0032] (11)In the connector in (9) or (10), it is also possible that the base member or the fitting guide groove has a guide surface, and as the sliding protrusion moves along the extending direction of the fitting guide groove, the guide surface guides the cover member in a direction approaching the base member.

[0033] In this case, when the sliding protrusion is moved along the guiding groove, the lid member approaches the base member, and the wobbling between the lid member and the base member can be suppressed.

[0034] (12) In any one of the connectors (1) to (11), it is also possible that a first stopper for preventing the first terminal from coming off is formed at the bottom of the first setting recess, and a second stopper for preventing the second terminal from coming off is formed at the bottom of the second setting recess.

[0035] Thereby, it is possible to prevent the first terminal and the second terminal from coming off from the bottoms of the first setting recess and the second setting recess, respectively. Thereby, it is easy to align the posture of the first terminal in the first setting recess and the posture of the second terminal in the second setting recess.

[0036] [Details of Embodiments of the Present Invention] Hereinafter, a specific example of the connector of the present invention will be described with reference to the drawings. In addition, the present invention is not limited to these examples, but is shown by the claims, and is intended to include all modifications within the meaning and scope equivalent to the claims.

[0037] [Embodiment] Hereinafter, the connector according to the embodiment will be described. Figure 1 And Figure 2 is a perspective view showing the connector 20. Figure 3 And Figure 4 is an exploded perspective view showing the connector 20. Figure 5 is Figure 1 a cross-sectional view taken along line V-V. Figure 6 is Figure 1 a cross-sectional view taken along line VI-VI. In Figures 3 to 6 the first terminal 10A and the second terminal 10B are shown. In Figures 3 to 5 the electric wire 18 is indicated by a two-dot chain line.

[0038] [Overall Structure of Connector] The overall structure of the connector 20 will be described. The connector 20 holds the first terminal 10A and the second terminal 10B.

[0039] The first terminal 10A and the second terminal 10B are formed by stamping a metal plate or the like. The first terminal 10A includes a covering crimping portion 11A, a core wire crimping portion 12A, and a terminal connection portion 13A. The covering crimping portion 11A is a portion that is crimped to the covering portion at the end of the electric wire 18. The core wire crimping portion 12A is a portion that is crimped to the core wire portion exposed at the end of the electric wire 18. The terminal connection portion 13A is a portion that is connected to the opposing terminal, and is formed in a cylindrical shape, for example. The covering crimping portion 11A, the core wire crimping portion 12A, and the terminal connection portion 13A are arranged linearly in this order. The thicknesses of the covering crimping portion 11A and the terminal connection portion 13A are greater than the thickness of the core wire crimping portion 12A. Therefore, when the first terminal 10A is viewed from the side, a depression is observed on the core wire crimping portion 12A and between the covering crimping portion 11A and the terminal connection portion 13A.

[0040] The second terminal 10B also includes a covering crimping portion 11B, a core wire crimping portion 12B, and a terminal connection portion 13B, similarly to the first terminal 10A.

[0041] In addition, the first terminal 10A and the second terminal 10B may be terminals having the same dimensions, raw materials, etc., or may be terminals having different dimensions or raw materials.

[0042] In the present embodiment, the connector 20 includes a plurality (two in this case) of the first terminals 10A and a plurality (two in this case) of the second terminals 10B. The plurality of first terminals 10A are arranged in a row in a side-by-side state. The plurality of second terminals 10B are also arranged in a row in a side-by-side state. The plurality of first terminals 10A and the plurality of second terminals 10B are adjacent to each other. That is, the connector 20 holds the plurality of first terminals 10A and the plurality of second terminals 10B in a first layer and a second layer. In addition, the number of the first terminals 10A and the second terminals 10B held by the connector 20 is arbitrary.

[0043] In the following description, in the extending direction of the first terminal 10A, the terminal connection portion 13A side may be referred to as the front side, and the covering crimping portion 11A side may be referred to as the rear side. Also, the first terminal 10A side may be referred to as the lower side, and the second terminal 10B side may be referred to as the upper side. Further, the left-right direction may be referred to assuming a state of standing on the first terminal 10A and facing the front side.

[0044] The connector 20 includes a base member 30, an internal member 50, and a cover member 70. The base member 30, the internal member 50, and the cover member 70 are each a molded member formed of resin or the like.

[0045] The base member 30 has a first setting recess 32, and the first terminal 10A is disposed in the first setting recess 32. The first setting recess 32 is a recess defined downward and laterally. By accommodating the first terminal 10A in the first setting recess 32, it is supported from below and positioned in the lateral direction. The front of the first setting recess 32 is open. The mating-side terminal enters the first setting recess 32 from the front and is connected to the first terminal 10A. The rear of the first setting recess 32 is open, and the wire 18 connected to the first terminal 10A is led out of the connector 20 through this rear opening. The upper part of the first setting recess 32 is open, and the first terminal 10A is set into the first setting recess 32 through this upper opening.

[0046] The internal member 50 overlaps the base member 30 so as to close the upper opening on the opposite side of the bottom of the first setting recess 32. By overlapping the internal member 50 with the base member 30, the first terminal 10A is held in the first setting recess 32.

[0047] In addition, the internal member 50 has a second setting recess 52, and the second terminal 10B is disposed in the second setting recess 52. The second setting recess 52 is a recess defined downward and laterally and open in the front-rear and upper directions, similar to the first setting recess 32. In the same manner as the first terminal 10A is accommodated in the first setting recess 32, the second terminal 10B is accommodated in the second setting recess 52.

[0048] The cover member 70 overlaps the internal member 50 so as to close the upper opening on the opposite side of the bottom of the second setting recess 52. By overlapping the cover member 70 with the internal member 50, the second terminal 10B is held in the second setting recess 52.

[0049] In a state where the cover member 70 overlaps the internal member 50, the internal member 50 is sandwiched between the base member 30 and the cover member 70. In this state, the cover member 70 and the base member 30 are joined in contact. Thereby, the base member 30, the internal member 50, and the cover member 70 are assembled into one connector 20.

[0050] In addition, the fact that the cover member 70 and the base member 30 are joined in contact means that the cover member 70 and the base member 30 are in direct contact and can be treated as one object. In the present embodiment, by engaging the cover member 70 with the base member 30, the internal member 50 between the cover member 70 and the base member 30 can also be treated integrally with the cover member 70 and the base member 30.

[0051] As described above, in a state where the base member 30, the internal member 50, and the cover member 70 are assembled, the base member 30, the internal member 50, and the cover member 70 are in contact with each other. For example, the base member 30 is in contact with both the internal member 50 and the cover member 70. Therefore, it is easy to reduce the deviation of the relative positional relationship of the three members 30, 50, and 70.

[0052] Each member will be described in more detail.

[0053] <Base member> The base member 30 includes a bottom plate portion 34, an intermediate wall 36, and a pair of outer walls 40.

[0054] The bottom plate portion 34 is formed in a square plate shape. The left - right width of the bottom plate portion 34 is greater than or equal to the juxtaposed width of a plurality of first terminals 10A, and the front - rear length of the bottom plate portion 34 is greater than or equal to the length of the first terminal 10A.

[0055] An intermediate wall 36 is erected at the middle portion in the width direction of the bottom plate portion 34. The intermediate wall 36 is in a rectangular plate shape along the front - rear and up - down directions. When the base member 30 holds three or more first terminals 10A, sometimes a plurality of intermediate walls are erected on the bottom plate portion.

[0056] A pair of outer walls 40 are erected at positions on the upper surface of the bottom plate portion 34 that are separated from the intermediate wall 36 in the left - right direction. The outer walls 40 are in a rectangular plate shape along the front - rear and up - down directions. A gap greater than or equal to the width of the first terminal 10A is formed between the intermediate wall 36 and the outer walls 40. The above - mentioned first setting recess 32 is a depression defined by the upper surface of the bottom plate portion 34, any one side surface of the intermediate wall 36, and the inner surface of any one of the outer walls 40.

[0057] A first stopper 33 that protrudes locally in the front - rear direction is formed at the bottom of the first setting recess 32. The first stopper 33 is a convex portion formed between the intermediate wall 36 and the outer walls 40 in the middle portion in the front - rear direction of the bottom plate portion 34.

[0058] The first terminal 10A is disposed in the first setting recess 32 in a state where the depression between the covering crimping portion 11A and the terminal connection portion 13A faces the bottom of the first setting recess 32. Then, the first stopper 33 is inserted into the depression between the covering crimping portion 11A and the terminal connection portion 13A. Thus, the first stopper 33 positions the first terminal 10A in its length direction and prevents the first terminal 10A from coming off.

[0059] Positioning recesses 36g, 40g that are locally recessed downward are formed at the upper side edges of the intermediate wall 36 and the pair of outer walls 40. By inserting the positioning protrusions 56p, 60p of the internal member 50 into the positioning recesses 36g, 40g, the internal member 50 is positioned in the front - rear direction with respect to the base member 30.

[0060] On the upper side edges of the intermediate wall 36 and the pair of outer walls 40, positioning convex portions 40p that protrude locally upward are formed. By fitting the positioning convex portions 40p into the positioning concave portions 60g of the internal component 50, the internal component 50 is positioned in the front-rear direction with respect to the base component 30.

[0061] Even if one of the positioning concave portions 36g, 40g and the positioning convex portion 40p is omitted, the internal component 50 is positioned in the front-rear direction with respect to the base component 30.

[0062] In the present embodiment, both sides of the bottom plate portion 34 protrude outward more than the pair of outer walls 40, but this is not necessary. The pair of outer walls may also protrude from the outer edges on both sides of the bottom plate portion.

[0063] On the outward-facing portions of the pair of outer walls 40, fitting guide grooves 38 for fitting with the cover component 70 are formed. The fitting guide grooves 38 will be described later together with the structure for fitting with the cover component 70.

[0064] In addition, the base component 30 has a front wall 44, and the front wall 44 has insertion guide holes 44h. The front wall 44 is formed in a square plate shape and protrudes from the front edge of the bottom plate portion 34. The front wall 44 extends in a direction orthogonal to the extending direction of the terminals 10A, 10B. The front wall 44 is located on the front side of the first setting recess 32 of the base component 30 and on the front side of the second setting recess 52 of the internal component 50. Insertion guide holes 44h are formed on the forward extension lines of the first setting recess 32 and the second setting recess 52 in the front wall 44. The insertion guide holes 44h may also have a guide surface that gradually expands toward the front side as the outer surface.

[0065] The mating terminals connected to the terminals 10A, 10B are connected to the terminals 10A, 10B in the first setting recess 32 and the second setting recess 52 through the insertion guide holes 44h. Since the insertion guide holes 44h function to guide the mating terminals toward the terminals 10A, 10B, it is preferable that the insertion guide holes 44h are arranged at a constant position with respect to the terminals 10A, 10B. Here, in the direction orthogonal to the terminals 10A, 10B, the terminal 10A is positioned between the base component 30 and the internal component 50, and the terminal 10B is positioned between the internal component 50 and the cover component 70. Therefore, if both the internal component 50 and the cover component 70 are positioned with respect to the base component 30 as a reference, it is easy to position the terminals 10A, 10B at a constant position with respect to the insertion guide holes 44h.

[0066] <Internal Component> The internal component 50 includes a bottom plate portion 54, an intermediate wall 56, and a pair of outer walls 60.

[0067] The bottom plate portion 54 is formed in a square plate shape. The left - right width of the bottom plate portion 54 is greater than or equal to the juxtaposed width of a plurality of second terminals 10B, and the front - rear length of the bottom plate portion 54 is greater than or equal to the length of the second terminal 10B. Here, the left - right width of the bottom plate portion 54 is less than the left - right width of the bottom plate portion 54, and the front - rear length of the bottom plate portion 54 is the same as the front - rear length of the bottom plate portion 34.

[0068] An intermediate wall 56 is erected at the middle portion in the width direction of the bottom plate portion 54. The intermediate wall 56 is in a rectangular plate shape along the front - rear and up - down directions. When the base member 30 holds three or more second terminals 10B, sometimes a plurality of intermediate walls are erected on the bottom plate portion.

[0069] A pair of outer walls 60 are erected at positions on the upper surface of the bottom plate portion 54 that are separated from the intermediate wall 56 in the left - right direction. The outer walls 60 are in a rectangular plate shape along the front - rear and up - down directions. A gap greater than or equal to the width of the second terminal 10B is formed between the intermediate wall 56 and the outer walls 60. The above - mentioned second setting recess 52 is a depression delimited by the upper surface of the bottom plate portion 54, any one side surface of the intermediate wall 56, and the inner surface of any one of the outer walls 60.

[0070] A second stopper 53 that protrudes locally in the front - rear direction is formed at the bottom of the second setting recess 52. The second stopper 53 is a convex portion formed between the intermediate wall 56 and the outer walls 60 in the bottom plate portion 54 and at the middle portion in the front - rear direction.

[0071] The second terminal 10B is disposed in the second setting recess 52 in a state where the depression between the coated crimping portion 11B and the terminal connection portion 13B faces the bottom of the second setting recess 52. Then, the second stopper 53 is inserted into the depression between the coated crimping portion 11B and the terminal connection portion 13B. Thus, the second stopper 53 positions the second terminal 10B in its long - side direction and prevents the second terminal 10B from coming off.

[0072] Positioning convex portions 56p, 60p that protrude locally downward are formed on the extensions of the lower sides of the intermediate wall 56 and the pair of outer walls 60 at the bottom of the bottom plate portion 54 (refer to Figure 4 ). By inserting the positioning convex portions 56p, 60p into the positioning concave portions 36g, 40g of the base member 30, the internal component 50 is positioned relative to the base member 30 in the front - rear direction.

[0073] A positioning concave portion 60g that is locally recessed is formed in a part of the bottom plate portion 54 in the long - side direction. By inserting the positioning convex portion 40p of the base member 30 into this positioning concave portion 60g, the internal component 50 is positioned relative to the base member 30 in the front - rear direction.

[0074] Even if one of the positioning convex portions 56p, 60p and the positioning concave portion 60g is omitted, the internal component 50 is positioned in the front-rear direction with respect to the base component 30.

[0075] In a state where the first terminal 10A is disposed in the first setting recess 32, the internal component 50 overlaps the base component 30. In this state, by the bottom of the bottom plate portion 54 of the internal component 50 contacting the upper ends of the intermediate wall 36 and the pair of outer walls 40 of the base component 30, the minimum distance of the intermediate wall 36 in the up-down direction with respect to the base component 30 is restricted.

[0076] As described later, the internal component 50 is held in a state of being pressed against the base component 30 by the cover component 70. Accordingly, the lower surface of the bottom plate portion 54 contacts the upper surface of the first terminal 10A, restricting the upward movement of the first terminal 10A. In the present embodiment, the terminal connection portion 13A of the first terminal 10A is sandwiched between the bottom of the first setting recess 32 and the downward-facing surface of the bottom plate portion 54, thereby restricting the up-down position of the first terminal 10A. Here, an elongated convex portion is formed in a portion of the bottom plate portion 54 corresponding to the front region of the first setting recess 32, and this convex portion is disposed within the first setting recess 32 to restrict the upward movement of the first terminal 10A. Since the upward movement of the first terminal 10A is restricted, the first stopper 33 is held in a state of being inserted into the recess of the first terminal 10A, thereby restricting the front-rear movement of the first terminal 10A. Further, the first terminal 10A is located between the two side surfaces of the first setting recess 32, thereby restricting the left-right position. Therefore, by holding the internal component 50 in a state of being pressed against the base component 30, the first terminal 10A is held in a constant position within the first setting recess 32.

[0077] <Cover component> The cover component 70 is a component that overlaps the internal component 50 so as to close the opening on the opposite side of the bottom of the second setting recess 52. Further, the cover component 70 is joined to the base component 30 in a contacting state. Preferably, the cover component 70 and the base component 30 are in a contacting state such that they press against each other in the up-down direction.

[0078] More specifically, the cover component 70 includes a cover main body 72 and a pair of locking walls 74.

[0079] The cover main body 72 is formed in a square plate shape. The left-right width of the cover main body 72 is greater than or equal to the juxtaposed width of the plurality of second setting recesses 52, and the front-rear length of the bottom plate portion 54 is greater than or equal to the length of the second terminal 10B. In a state where the cover component 70 overlaps the internal component 50, the cover main body 72 can close the upper opening on the opposite side of the bottom of the plurality of second setting recesses 52.

[0080] With the second terminal 10B disposed in the second setting recess 52, the cover member 70 overlaps with the internal member 50. In this state, the minimum distance of the cover main body 72 relative to the internal member 50 in the vertical direction is restricted by the bottom of the cover main body 72 coming into contact with the intermediate wall 56 and the upper ends of the pair of outer walls 60 of the internal member 50.

[0081] As described later, by combining the cover member 70 with the base member 30, the cover main body 72 is held in a state of being pressed against the internal member 50. Therefore, the lower surface of the cover main body 72 comes into contact with the upper surface of the second terminal 10B, restricting the upward movement of the second terminal 10B. In the present embodiment, the terminal connection portion 13B of the second terminal 10B is sandwiched between the bottom of the second setting recess 52 and the downward-facing surface of the cover main body 72, thereby restricting the vertical position of the second terminal 10B. Here, an elongated convex portion is formed in a portion of the cover main body 72 corresponding to the front region of the second setting recess 52, and this convex portion is disposed within the second setting recess 52 to restrict the upward movement of the second terminal 10B. Since the upward movement of the second terminal 10B is restricted, the second stopper 53 is held in a state of being inserted into the recess of the second terminal 10B, thereby restricting the forward and backward movement of the second terminal 10B. In addition, since the second terminal 10B is located between the two side surfaces of the second setting recess 52, the position in the left-right direction is restricted. Therefore, by holding the cover member 70 in a state of being pressed against the internal member 50, the second terminal 10B is held in a constant position within the second setting recess 52.

[0082] The pair of locking walls 74 are shaped to include square plate-like portions, and extend from both side portions of the cover main body 72 through the outer sides of both sides of the internal member 50 toward both sides of the base member 30. The pair of locking walls 74 are locked to both sides of the base member 30. Thereby, the cover member 70 can be combined with the base member 30 in a contacting state.

[0083] The bottom plate portion 34 of the base member 30 is located at the bottom of the connector 20, the cover main body 72 is located above the connector 20, and the pair of locking walls 74 are located on both sides of the connector 20. Therefore, the base member 30 and the cover member 70 surround the periphery of the internal member 50. In the present embodiment, the base member 30 and the cover member 70 surround the periphery of the internal member 50 in such a manner that the internal member 50 is not exposed on the upper, lower, left, and right surfaces surrounding the terminals 10A and 10B.

[0084] <Engaging Structure for Combination> A structure for combining the cover member 70 with the base member 30 will be described.

[0085] On the inner surfaces of a pair of locking walls 74 of the base member 30, sliding protrusions 76a, 76b, 76c are formed. For example, a plurality of sliding protrusions 76a, 76b, 76c are formed at intervals along the top edge of the inner surface of the locking wall 74. The sliding protrusions 76a, 76b, 76c are arranged in order from the front to the back.

[0086] On the outer surfaces of a pair of outer walls 40 of the base member 30, fitting guide grooves 38 extending in the front-rear direction are formed. More specifically, groove-forming protrusions 46a, 46b, 46c are formed at positions on the outer surfaces of the outer walls 40 that are away from the bottom plate portion 34. For example, a plurality of groove-forming protrusions 46a, 46b, 46c are formed at intervals along the top edge of the outer surface of the outer wall 40. The plurality of groove-forming protrusions 46a, 46b, 46c are arranged in order from the front to the back. The fitting guide groove 38 is formed by the outer surface of the outer wall 40, the downward surfaces of the plurality of groove-forming protrusions 46a, 46b, 46c, and the upward surface of the side portion of the bottom plate portion 34. The fitting guide groove 38 guides the sliding protrusions 76a, 76b, 76c along the extending direction of the terminals 10A, 10B.

[0087] Here, the positioning recess 36g is located between the front groove-forming protrusion 46a and the groove-forming protrusion 46b in the middle in the front-rear direction. The positioning protrusion 40p is connected above the groove-forming protrusion 46b in the middle in the front-rear direction. These structures are not essential.

[0088] A gap through which the front sliding protrusion 76a can pass in the up-down direction is provided between the front groove-forming protrusion 46a and the groove-forming protrusion 46b in the middle in the front-rear direction. A gap through which the middle sliding protrusion 76b in the front-rear direction can pass in the up-down direction is provided between the groove-forming protrusion 46b in the middle in the front-rear direction and the rear groove-forming protrusion 46c. In addition, a gap through which the groove-forming protrusion 46b in the middle in the front-rear direction can pass in the up-down direction is provided between the front sliding protrusion 76a and the middle sliding protrusion 76b in the front-rear direction. In addition, a gap through which the rear groove-forming protrusion 46c can pass in the up-down direction is provided between the middle sliding protrusion 76b in the front-rear direction and the rear sliding protrusion 76c.

[0089] On a portion of the front groove-forming protrusion 46a on the side of the bottom plate portion 34, a position restricting surface 46af1 (see Figure 3 , Figures 6 to 8 ) is formed. The position restricting surface 46af1 is parallel to the upward surface of the bottom plate portion 34. The interval between the position restricting surface 46af1 and the bottom plate portion 34 is set to be the same as the up-down dimension of the sliding protrusion 76a.

[0090] On the part of the front side groove-forming convex portion 46a on the side of the bottom plate portion 34 and on the rear side of the position restricting surface 46af1, a guiding surface 46af2 is formed (refer to Figure 3 , Figure 7 and Figure 8 ). The guiding surface 46af2 is an inclined surface that gradually inclines away from the bottom plate portion 34 towards the rear. When the sliding projection 76a moves between the front side groove-forming convex portion 46a and the bottom plate portion 34 along the extending direction of the fitting guiding groove 38, the guiding surface 46af2 guides the sliding projection 76a towards the bottom plate portion 34. Thereby, the cover member 70 moves towards the base member 30 as it moves forward.

[0091] On the rear-facing part of the front side groove-forming convex portion 46a, an interference surface 46af3 is formed (refer to Figure 3 , Figure 7 and Figure 8 ). The interference surface 46af3 extends in a direction intersecting the extending direction of the fitting guiding groove 38, here an orthogonal direction. When the cover member 70 is fitted to the base member 30, if the internal member 50 or the cover member 70 is in a state of floating away from the normal assembled state with respect to the base member 30, the sliding projection 76a interferes with the interference surface 46af3. Thereby, the movement of the cover member 70 is obstructed.

[0092] In the groove-forming convex portion 46b in the middle in the front-rear direction, position restricting surfaces 46bf1, guiding surfaces 46bf2, and interference surfaces 46bf3 corresponding to the above-mentioned position restricting surface 46af1, guiding surface 46af2, and interference surface 46af3 are also formed (refer to Figure 7 and Figure 8 ).

[0093] In addition, based on or instead of the above-mentioned guiding surfaces 46af2, 46bf2, guiding surfaces can be formed on the sliding projections 76a, 76b. In this case, it is sufficient to form guiding surfaces that gradually incline downward towards the rear on the upward-facing part and the part near the rear end of the sliding projections 76a, 76b.

[0094] In addition, an anti-disengagement convex portion 48 is formed on the outer surface of the outer wall 40, here at a rear position. The anti-disengagement convex portion 48 is formed in a shape including a part where the protruding dimension gradually decreases towards the rear. An anti-disengagement convex portion 78 is formed on the inner surface of the locking wall 74, here at a position near the rear. The anti-disengagement convex portion 78 is formed in a shape including a part where the protruding dimension gradually decreases towards the front.

[0095] In the present embodiment, the anti - detachment convex portion 78 is located between the sliding convex portion 76b in the middle in the front - rear direction and the sliding convex portion 76c at the rear side, and the anti - detachment convex portion 48 is located between the groove - forming convex portion 46b in the middle in the front - rear direction and the groove - forming convex portion 46c at the rear side. During the assembly operation of the base member 30 and the cover member 70, the anti - detachment convex portion 78 can pass between the groove - forming convex portion 46b in the middle in the front - rear direction and the groove - forming convex portion 46c at the rear side and behind the anti - detachment convex portion 48 and move in the up - down direction.

[0096] Moreover, by accommodating the sliding convex portions 76a, 76b, 76c in the assembly guiding groove 38, the positioning of the cover member 70 relative to the base member 30 in the up - down direction is performed. In particular, by the sliding convex portions 76a, 76b being located between the position - limiting surfaces 46af1, 46bf1 and the upper surface of the bottom plate portion 34, the positioning of the cover member 70 is performed. In addition, with the front end of the cover member 70 in contact with the rear surface of the front wall 44, the anti - detachment convex portion 48 and the anti - detachment convex portion 78 are anti - detachably engaged, thereby performing the positioning of the cover member 70 relative to the base member 30 in the front - rear direction.

[0097] In the present embodiment, on the outer wall 60 of the internal member 50, convex portions are formed in a shape that extends the above - mentioned groove - forming convex portions 46b, 46c and the anti - detachment convex portion 48 upward. The convex portions in the internal member 50 can also be omitted.

[0098] In addition, it is not necessary to arrange the plurality of sliding convex portions and the plurality of groove - forming convex portions at intervals in the front - rear direction. It is also possible to form continuous sliding convex portions and continuous groove - forming convex portions. In this case, the sliding convex portions only need to be arranged in the assembly guiding groove from the rear side of the base member.

[0099] <Flattening rib> The above - mentioned base member 30, internal member 50 or cover member 70 may also have flattening ribs 80, 82. The flattening ribs 80, 82 protrude in the assembly direction of the base member 30, internal member 50 and cover member 70 and can be crushed in the assembled state of those members. The so - called assembly direction is the stacking direction in which the base member 30, internal member 50 and cover member 70 are combined. In the present embodiment, it is the up - down direction. In Figure 6 it, the shapes of the flattening ribs 80, 82 before crushing are shown by dashed lines.

[0100] That is, in a state where the internal component 50 is sandwiched between the base component 30 and the lid component 70, the lid component 70 and the base component 30 are joined together. Within the tolerance range, the internal component arrangement space for the internal component 50 between the lid component 70 and the base component 30 may be larger or smaller than the actual internal component 50. If the internal component arrangement space is larger than the actual internal component 50, the internal component 50 may wobble. If the internal component arrangement space is smaller than the actual internal component 50, the joining of the lid component 70 to the base component 30 may not be well performed.

[0101] By the base component 30, the internal component 50, or the lid component 70 having the flattening ribs 80, 82, the flattening ribs 80, 82 can fill the gaps between the components 30, 50, 70 and suppress wobbling. Further, if the internal component arrangement space is smaller than the actual internal component 50, the flattening ribs 80, 82 are crushed, enabling the joining of the lid component 70 to the flattened base component 30 to be established.

[0102] In the present embodiment, the lid component 70 has a first flattening rib 80 located at the contact portion between the base component 30 and the lid component 70. More specifically, the first flattening rib 80 that protrudes upward is formed on the upward-facing surface of the front sliding protrusion 76a in the lid component 70.

[0103] The first flattening rib 80 is formed in an elongated convex shape in the front-rear direction. Further, the first flattening rib 80 is formed in a shape that gradually narrows from the base end side toward the tip end side. Here, when viewed in the front-rear direction, the first flattening rib 80 is formed in a triangular shape. Therefore, when the groove-forming convex portion 46a in the base component 30 is pressed against the first flattening rib 80, the first flattening rib 80 can be sequentially crushed from the tip end side.

[0104] Further, the rear end portion of the first flattening rib 80 is formed in a shape where the height gradually decreases toward the rear.

[0105] The first flattening rib 80 may also be formed in other parts of the lid component 70. For example, it may be formed at the tips of other groove-forming convex portions 46b, 46c, the pair of locking walls 74, etc. If the first flattening rib 80 is formed near the front edge closer to the front wall 44 than the rear edge far from the front wall 44, the wobbling between the base component 30 and the lid component 70 can be eliminated near the front wall 44. Further, near the front wall 44, it is easy to arrange the terminals 10A, 10B at a constant position relative to the front wall 44.

[0106] The first flattening rib 80 may also be formed in the base component 30. For example, it may be formed on the surface on the side of the bottom plate portion 34 in the groove-forming convex portions 46a, 46b, 46c in the base component 30.

[0107] In addition, the internal component 50 has a second flattened rib 82 at the contact portion between the internal component 50 and the cover component 70. More specifically, the second flattened rib 82 that protrudes upward is formed at a position closer to the front end of the top end portions of a pair of outer walls 60 in the internal component 50. The second flattened rib 82 is formed in an elongated convex shape in the front-rear direction. The rear end portion of the second flattened rib 82 is formed in a shape in which the protruding dimension gradually decreases toward the rear.

[0108] Similar to the first flattened rib 80, the second flattened rib 82 is formed in a shape that gradually narrows from the base end side toward the top end side. Here, when viewed in the front-rear direction, the second flattened rib 82 is formed in a triangular shape. Therefore, when the cover main body 72 of the cover component 70 is pressed against the second flattened rib 82, the second flattened rib 82 is sequentially crushed from the top end side.

[0109] The second flattened rib 82 may also be formed in other parts of the internal component 50. For example, the second flattened rib 82 may be formed at a position closer to the rear end of a pair of outer walls 40, or may be formed on the intermediate wall 56. If the second flattened rib 82 is formed at a position closer to the front wall 44 than the center in the front-rear direction, that is, near the front edge closer to the front wall 44 than the rear edge away from the front wall 44, the shaking between the internal component 50 and the cover component 70 can be eliminated near the front wall 44. In addition, near the front wall 44, it is easy to dispose the terminal 10B at a constant position with respect to the front wall 44.

[0110] The second flattened rib 82 may also be formed on the cover component 70. For example, the second flattened rib may be formed at a position on the lower surface of the cover main body 72 that faces the outer wall 60.

[0111] Preferably, the base component 30 and the internal component 50 do not abut via the flattened rib. That is, preferably, between the base component 30 and the internal component 50, a state is formed in which portions maintaining a constant shape are in contact with each other. In the present embodiment, the upper end of the outer wall 40 and the upper end of the intermediate wall 36 are in a state of being in contact with the lower surface of the bottom plate portion 54 while maintaining a stable shape. Therefore, in a state where the internal component 50 is pressed against the base component 30, the positional relationship between the internal component 50 and the base component 30 is maintained constant as compared with the case where the flattened rib is interposed therebetween.

[0112] That is, for both the base component 30 and the internal component 50 having a constant positional relationship, the cover component 70 is positioned in such a manner that shaking is suppressed by the flattened ribs 80 and 82.

[0113] <Regarding the example of the assembly operation> An example of the assembly operation of the connector 20 will be described.

[0114] The first terminals 10A are respectively arranged in the first setting recesses 32 of the base member 30. The internal member 50 overlaps the base member 30 from above. At this time, the positioning convex portion 40p is inserted into the positioning concave portion 60g, and the positioning convex portions 56p and 60p are inserted into the positioning concave portion 36g. Thus, the internal member 50 is positioned relative to the base member 30 in the front-rear direction.

[0115] The second terminals 10B are respectively arranged in the second setting recesses 52 of the internal member 50. After that, as Figure 7 shown, the cover member 70 overlaps the internal member 50 from above. More specifically, in a state where the cover member 70 is arranged at a position shifted rearward relative to the base member 30 and the internal member 50, a pair of locking walls 74 are arranged on the outer sides of both sides of the internal member 50. At this time, the front sliding protrusion 76a passes between the front groove-forming protrusion 46a and the middle-of-front-and-rear groove-forming protrusion 46b, the middle-of-front-and-rear sliding protrusion 76b and the anti-disengagement protrusion 78 pass between the middle-of-front-and-rear groove-forming protrusion 46b and the rear groove-forming protrusion 46c, and the rear sliding protrusion 76c passes behind the rear groove-forming protrusion 46c. Thus, the pair of locking walls 74 pass on the two outer sides of the internal member 50 and are arranged on a pair of outer walls 40 of the base member 30.

[0116] As Figure 8 shown, in a state where the sliding protrusions 76a, 76b, and 76c cross the groove-forming protrusions 46a, 46b, and 46c and reach the fitting guide groove 38, the cover member 70 is pressed forward relative to the base member 30 and the internal member 50.

[0117] At this time, when the internal member 50 floats upward relative to the base member 30, or the cover member 70 floats upward relative to the internal member 50, the sliding protrusions 76a and 76b interfere with the interference surfaces 46af3 and 46bf3. Therefore, when the cover member 70 cannot be moved forward, it is possible to detect the occurrence of the floating of the internal member 50 or the floating of the cover member 70.

[0118] When the sliding protrusions 76a, 76b, and 76c move in the fitting guide groove 38, the sliding protrusions 76a and 76b are pressed toward the bottom plate portion 34 side by the guide surfaces 46af2 and 46bf2 and move, and can enter between the position limiting surfaces 46af1, 46bf1 and the bottom plate portion 34. Therefore, the shaking of the cover member 70 relative to the base member 30 can be suppressed.

[0119] When the cover member 70 moves forward until the front end portion of the cover member 70 contacts the inner surface of the front wall 44, the anti-disengagement protrusion 78 is locked to the anti-disengagement protrusion 48 in an anti-disengagement state.

[0120] The connector 20 is assembled as described above.

[0121] <Effect, etc.> In the connector 20 configured as described above, with the internal component 50 sandwiched between the base component 30 and the lid component 70, the lid component 70 and the base component 30 are joined in a contacting state. Therefore, the first terminal 10A in the first setting recess 32 is positioned between the base component 30 and the internal component 50 positioned with reference to the base component 30. In addition, the second terminal 10B in the second setting recess 52 is positioned between the internal component 50 positioned with reference to the base component 30 and the lid component 70. Therefore, the cumulative dimensional tolerances of the multiple components 30, 50, 70 are less likely to affect the relative positional relationship between the first terminal 10A and the second terminal 10B. Therefore, the relative positional deviation between the different terminals 10A, 10B can be reduced.

[0122] For example, if a structure in which the base component and the lid component are respectively mounted with reference to the internal component is assumed, the relative positional relationship between the base component and the lid component can vary within the range of the cumulative dimensional tolerances of the three components. Therefore, considering the relative positional relationship between the terminal positioned between the internal component and the base component and the terminal positioned between the internal component and the lid component is likely to deviate significantly. If the relative positional relationship of the terminals in each layer is likely to deviate, it is not possible to correctly hold the terminals in each layer with respect to the opposing terminals in the arrangement, and it may be difficult to insert the opposing terminals into the terminals in each layer simultaneously.

[0123] In the present embodiment, the internal component 50 and the lid component 70 can be positioned with reference to the base component 30, and the relative positional deviation of the terminals 10A, 10B between those components can also be reduced. Therefore, it is easy to insert the opposing terminals into the terminals 10A, 10B in each layer.

[0124] In addition, since the base component 30 and the lid component 70 surround the periphery of the internal component 50, compared with the case where the outer shape of the connector 20 is formed by combining three or more components, the shape error of the connector 20 can be reduced.

[0125] In addition, the base component 30 has a front wall 44, and the front wall 44 has an insertion guide hole 44h. With reference to the base component 30, the first terminal 10A and the second terminal 10B are positioned by the internal component 50 and the lid component 70. Therefore, the opposing terminal guided by the insertion guide hole 44h is smoothly inserted into the first terminal 10A and the second terminal 10B.

[0126] In addition, the base component 30, the internal component 50, or the lid component 70 has flattening ribs 80, 82. The flattening ribs 80, 82 protrude in the joining direction of those components and can be crushed in the joined state of those components. Therefore, the shaking between the components 30, 50, 70 can be suppressed.

[0127] In addition, the base member 30 or the lid member 70 has a first crush rib 80 located at the contact portion between the base member 30 and the lid member 70, and the internal member 50 or the lid member 70 has a second crush rib 82 located at the contact portion between the internal member 50 and the lid member 70. Therefore, by crushing the crush ribs 80 and 82, the wobbling between the base member 30 and the lid member 70 and the wobbling between the internal member 50 and the lid member 70 can be suppressed. As a result, the wobbling of the entire connector 20 can be suppressed. In addition, since the crush rib does not need to be interposed between the base member 30 and the internal member 50, the relative positional error between the base member 30 and the internal member 50 can be reduced. As a result, the positional error between the first terminal 10A in the first setting recess 32 of the base member 30 and the second terminal 10B in the second setting recess 52 of the internal member 50 can be reduced.

[0128] In addition, if the crush ribs 80 and 82 are shaped such that they gradually narrow from the base end side toward the tip end side, they can be gradually crushed from the tip end according to the size of the gap between the respective members 30, 50, and 70.

[0129] In addition, if the crush ribs 80 and 82 are located near the front wall 44, the wobbling of the respective members 30, 50, and 70 can be suppressed near the insertion guide hole 44h. As a result, near the insertion guide hole 44h, the terminals 10A and 10B are positioned more accurately, and the connection operation of the mating terminals can be easily and smoothly performed.

[0130] In addition, the lid member 70 includes a pair of locking walls 74 that extend from both sides of the lid body 72 toward both sides of the base member 30 through the outer sides of both sides of the internal member 50 and are locked to both sides of the base member 30. Therefore, a structure in which the lid member 70 is joined to the base member 30 in a state where the internal member 50 is sandwiched between the base member 30 and the lid member 70 can be easily realized.

[0131] In addition, sliding protrusions 76a, 76b, and 76c are formed on the pair of locking walls 74, and mating guide grooves 38 are formed on both sides of the base member 30. Therefore, in a state where the internal member 50 and the base member 30 overlap, the lid member 70 and the base member 30 are joined by moving the sliding protrusions 76a, 76b, and 76c along the mating guide grooves 38 to assemble the connector 20.

[0132] Since the interference surfaces 46af3 and 46bf3 are formed on the base member 30, the base member 30 cannot be moved when the internal member 50 or the cover member 70 is floating. Therefore, it is possible to suppress assembly defects caused by the floating of the internal member 50 or the cover member 70. In particular, since it is difficult to observe the internal member 50 from the outside, it is possible to detect the floating of the internal member 50 based on whether the cover member 70 located on the outside can move.

[0133] In addition, since guide surfaces are formed on the base member 30 or the fitting guide groove 38, when the sliding protrusions 76a and 76b are moved along the fitting guide groove 38, the cover member 70 approaches the base member 30, and it is possible to suppress the shaking between the cover member 70 and the base member 30.

[0134] In addition, a first stopper 33 is formed at the bottom of the first setting recess 32, and a second stopper 53 is formed at the bottom of the second setting recess 52. Therefore, it is possible to prevent the first terminal 10A and the second terminal 10B from falling off outside the first setting recess 32 and the second setting recess 52. As a result, it is easy to make the postures of the first terminal 10A in the first setting recess 32 and the second terminal 10B in the second setting recess 52 coincide.

[0135] In addition, the respective structures described in the above-described embodiments and respective modification examples can be appropriately combined as long as they do not contradict each other. Description of Reference Numerals
