DETAILED DESCRIPTION

[0009] [Description of Embodiments of the Present Disclosure] First, embodiments of the present disclosure will be described by way of examples. The connector disclosed in the present invention is configured as follows: (1) It comprises: a terminal; a housing for accommodating the terminal; and a retaining member configured to be movable relative to the housing between a temporary locking position and a formal locking position, the retaining member having: a primary locking portion that is elastically deformable and locks the terminal at the temporary locking position; and a secondary locking portion that is formed in a fixed shape and moves away from the terminal at the temporary locking position and locks the terminal at the formal locking position.

[0010] The primary locking portion and the secondary locking portion are both formed on the retaining member, not on the housing. Therefore, the structure of the housing can be simplified. In addition, in this specification, "locking" means that the terminal is held in a manner that does not allow the terminal to be pulled out of the housing, for example, the concept of a state in which the primary locking portion and the secondary locking portion do not contact the terminal and are opposed to the terminal in a state in which the terminal is restricted from being pulled out.

[0011] (2) In the connector described in (1) above, preferably, the primary locking portion also locks the terminal at the final locking position. When the retainer is located at the formal locking position, the terminal is locked by the primary locking portion in addition to the secondary locking portion, so that the stability of the locking state of the primary locking portion and the secondary locking portion relative to the terminal can be improved.

[0012] (3) In the connector described in (2) above, preferably, a locking margin between the primary locking portion and the terminal at the final locking position is smaller than a locking margin between the primary locking portion and the terminal at the temporary locking position. In the above-mentioned structure (3), since it is not necessary to change the shape of the terminal according to the primary locking portion, it is possible to avoid complication of the shape of the terminal.

[0013] (4) In the connector described in (2) or (3) above, preferably, the primary locking portion has a locking surface, which extends along the moving direction from the temporary locking position toward the formal locking position and is opposite to the terminal at each position of the temporary locking position and the formal locking position. Since the locking surface faces the terminal at each of the temporary locking position and the final locking position and is not formed to correspond to each position independently, the structure of the primary locking portion can be simplified.

[0014] (5) In the connector described in any one of (1) to (4) above, preferably, the primary locking portion is formed in pairs on both sides of the secondary locking portion in the width direction intersecting the movement direction from the temporary locking position toward the formal locking position. Since the paired primary locking portions can lock the terminal from both sides in the width direction at least at the temporary locking position, the stability of the locking state of the primary locking portions with respect to the terminal can be further improved.

[0015] [Details of the embodiments of the present disclosure] Hereinafter, specific examples of the present disclosure will be described with reference to the drawings. In addition, the present invention is not limited to the examples, but is indicated by the claims, and includes all modifications within the meaning and scope equivalent to the claims.

[0016] <Implementation Method 1> like Figure 1 and Figure 2 As shown in FIG. 1 , the connector 10 of the first embodiment of the present disclosure includes a terminal 11, a housing 30, and a retainer 60. The connector 10 can be mated with a mating connector (not shown). In the following description, regarding the front-to-back direction, the side of the connector 10 that faces the mating connector at the beginning of mating is referred to as the front side. The up-down direction is used to describe the connector 10 of the first embodiment. Figures 1 to 11 In addition Figure 6 and Figure 8 In the first embodiment, the up-down direction is synonymous with the height direction, and the left-right direction is synonymous with the width direction. Figure 1 and Figure 2 In the figure, the front, the right, and the top are respectively indicated by arrows X, Y, and Z. In addition, illustration of parts that are not strongly related to the present disclosure is omitted.

[0017] (Terminal 11) like Figure 1 As shown, the terminal 11 is a so-called coaxial terminal and is connected to the terminal end of a coaxial cable (hereinafter referred to as the wire 100). Although not shown, the wire 100 is composed of a conductor, an insulating coating, a shield such as a braided wire, and an insulating sheath arranged concentrically in order from the center in the radial direction.

[0018] The terminal 11 includes a cylindrical outer conductor 12, an inner conductor 13 disposed inside the outer conductor 12, and a dielectric 14 disposed radially between the outer conductor 12 and the inner conductor 13. The outer conductor 12 and the inner conductor 13 are both conductive and are formed by stamping a metal plate. The dielectric 14 is made of an insulating material such as a synthetic resin.

[0019] The inner conductor 13 is disposed at the radial center of the terminal 11, and is electrically connected to the conductor of the electric wire 100. The dielectric 14 has a function of maintaining the inner conductor 13 and the outer conductor 12 in an insulated state.

[0020] The outer conductor 12 is arranged with its axis oriented in the front-rear direction. A crimping portion 15 is formed at the rear end of the outer conductor 12. The crimping portion 15 is crimped and fixed to the terminal end of the electric wire 100. The crimping portion 15 has a portion electrically connected to the shield of the electric wire 100.

[0021] A plurality of elastically deformable elastic contact portions 16 are formed at the front end portion of the outer conductor 12. Each elastic contact portion 16 is formed by dividing the front end portion of the outer conductor 12 in the circumferential direction. Each elastic contact portion 16 is elastically deformable in the radial direction. A counterpart outer conductor (not shown) is engaged between each elastic contact portion 16 and a dielectric 14 disposed inside each elastic contact portion 16. Each elastic contact portion 16 contacts and electrically connects the counterpart outer conductor when the connector 10 is engaged with the counterpart connector.

[0022] The outer conductor 12 has two flanges 17 and 18 extending all around the outer circumference of the outer conductor 12 between each elastic contact portion 16 and the crimping portion 15 in the front-to-back direction. Each flange 17 and 18 is arranged on the outer circumference of the outer conductor 12 at intervals in the front-to-back direction. The front flange 17 of each flange 17 and 18 has a locked surface 17s that is locked with the retaining member 60. The locked surface 17s is arranged on the rear surface of the flange 17 in the radial direction. Figure 8 As shown, the engaged surface 17 s is engaged with an engaging surface of the holder 60 described below.

[0023] (Housing 30) The housing 30 is made of synthetic resin such as Figure 3 , Figure 8 as well as Fig.11 As shown, there are cavities 31 and 32 that penetrate in the front-rear direction. The cavities 31 and 32 are formed in a circular cross section, and have a front cavity 31 on the front side and a rear cavity 32 on the rear side via mounting holes 34 and 35 described below.

[0024] like Figure 3 As shown in FIG. 1 , the housing 30 has a housing body 33 having a rectangular outer shape. The housing body 33 has mounting holes 34 and 35 in the middle portion in the front-rear direction, which are opened from the bottom surface to the left and right side surfaces. Figure 8 and Fig.11 As shown, the assembly holes 34 , 35 are communicated with the front cavity 31 and the rear cavity 32 .

[0025] The assembly hole has a main assembly hole 34 for receiving the retainer main body 61 described below and an end assembly hole 35 for receiving the top end of the arm portion 68b of the primary locking portion 68 described below. The main assembly hole 34 constitutes the main part of the assembly holes 34 and 35. The front and rear inner surfaces (surfaces facing each other in the front and rear directions) of the main assembly hole 34 have inner end surfaces 36 and 37 vertically extending in the up-down direction inside the housing main body 33. Figure 1As shown, the front end of the rear cavity 32 opens at the inner end surface 37 on the rear side. Figure 3 As shown in FIG. 1 , a stopper surface 38 is formed on the inner surface of the housing body 33 at a position forward and above the front inner end surface 36. The rear end of the front cavity 31 opens at the stopper surface 38. Figure 8 and Fig.11 As shown, the front flange portion 17 of the terminal 11 can hit the stop surface 38 and stop.

[0026] In addition, if Figure 3 As shown, an inner lower surface 39 extending relatively short in the front-to-back direction is formed on the inner surface of the housing body 33 and between the inner end surface 36 on the front side and the stop surface 38. The inner lower surface 39 is bent downward. A plurality of lower side ribs 41 ( Figure 3 Only one is shown in the figure). The lower ribs 41 are arranged on the inner lower surface 39 at intervals in the left-right direction. The front end of each lower rib 41 is connected to the stopper surface 38.

[0027] The inner surface of the upper side of the main body assembly hole 34 (the surface facing the lower surface opening) is set as an inner upper surface 42 that is curved upward. Figure 4 , Fig. 9 as well as Fig.10 As shown, a plurality of upper ribs 43 extending in the front-rear direction are formed on the inner upper surface 42. The upper ribs 43 are arranged on the inner upper surface 42 at intervals in the left-right direction. The front end of each upper rib 43 is connected to the stopper surface 38. The upper ribs 43 and the lower ribs 41 are in contact with the outer peripheral surface of the front flange portion 17 at intervals in the circumferential direction.

[0028] like Figure 3 As shown, the end assembly holes 35 are connected in pairs in the left-right direction relative to the main body assembly hole 34. Each end assembly hole 35 is formed in a rectangular cross-section, extends in the up-down direction, and the upper end opens at the inner lower surface 39, and the lower end opens at the lower surface of the housing body 33. Moreover, each end assembly hole 35 opens in the up-down direction relative to the inner end surface 36 on the front side.

[0029] In addition, if Figure 8 As shown, a pair of openings 44 are formed inside the housing body 33 and communicate with the left and right ends of the front cavity 31. Each opening 44 is formed in a rectangular cross-section and extends in the front-to-back direction, with the front end opening at the front surface of the housing body 33 (see Figure 2 ), and the rear end is opened at the stop surface 38. As described below, each opening 44 becomes a space for inserting a jig for extracting the terminal 11.

[0030] (Retaining member 60) The retainer 60 is made of synthetic resin and is assembled so as to be able to be in a temporary locking position (see Fig. 9 ) and the formal locking position (refer to Figure 2 and Fig.10 ). Although not shown in the figure, the retaining member 60 has a temporary locking structure that is locked to the housing 30 and retained at the temporary locking position, and a formal locking structure that is locked to the housing 30 and retained at the formal locking position. For the temporary locking structure and the formal locking structure, a well-known locking structure can be adopted as the locking structure of the retaining member 60 relative to the housing 30.

[0031] like Figure 8 and Fig.11 As shown, the retainer 60 has a retainer body 61 that is fitted into the body assembly hole 34. Figure 5 to Figure 7 As shown in FIG. 1 , the retainer body 61 has a curved concave front receiving surface 62 at the middle portion in the left-right direction at the front end portion of the upper surface. Figure 6 and Figure 7 As shown, the upper surface of the retainer body 61 has a curved concave rear receiving surface 63 at a position behind the front receiving surface 62. The rear receiving surface 63 is arranged at a position lower than the front receiving surface 62. A step surface 64 is formed between the front receiving surface 62 and the rear receiving surface 63 in a vertical direction.

[0032] A plurality of retainer side ribs 65 extending in the front-rear direction are formed on the rear receiving surface 63. The retainer side ribs 65 are arranged at intervals in the left-right direction on the rear receiving surface 63. The front end of each retainer side rib 65 is connected to the step surface 64. The retainer side ribs 65 and the upper side ribs 43 of the housing 30 are in contact with the outer peripheral surface of the rear flange portion 18 at intervals in the circumferential direction (not shown).

[0033] The front surface of the holder body 61 is arranged vertically in the up-down direction. Figure 5 As shown in FIG. 1 , a secondary stopper 66 (a portion above the dotted line in the figure) is formed at the upper end of the front surface of the retainer body 61 and extends in a curved shape along the front receiving surface 62 in the left-right direction. The secondary stopper 66 is a fixed surface that is arranged vertically toward the front in the retainer body 61 and does not elastically displace. The secondary stopper 66 is arranged on the opposite side of the step surface 64. Fig.10 and Fig.11 As shown, the secondary locking portion 66 faces the locked surface 17 s of the terminal 11 , and restricts the terminal 11 from being removed from the cavities 31 , 32 for a second time, following the primary locking portion 68 described below.

[0034] like Figure 5 to Figure 7As shown, a pair of side wall portions 67 are formed upright at the left and right ends of the upper surface of the holder body 61. The holder 60 has a pair of primary locking portions 68 protruding from the inner surfaces (opposing surfaces facing each other) of each side wall portion 67.

[0035] Each primary locking portion 68 includes a base end portion 68f protruding inward (central side in the left-right direction) from the inner surface of each side wall portion 67, an arm portion 68b bent from the top end side (inner end side) in the protruding direction of the base end portion 68f and extending forward, and a locking body 68c protruding from the inner surface of the arm portion 68b. Each primary locking portion 68 can be elastically deformed in the left-right direction with the base end portion 68f as a fulcrum.

[0036] like Figure 6 As shown in the figure, the base end portion 68f is protruded on the rear end side of the inner surface of each side wall portion 67. The arm portion 68b is arranged with a gap between the inner surface of the side wall portion 67, and tilts and displaces in the direction of reducing the gap when elastically deformed. The top end portion (the front end) of the arm portion 68b protrudes further forward than the front end (front surface) of the holder body 61.

[0037] The locking body 68c is protrudingly provided at the middle part of the arm portion 68b in the front-to-back direction. Specifically, the locking body 68c is protrudingly provided at a position slightly forward of the central position (the exact center) of the arm portion 68b in the front-to-back direction, and is arranged in the front-to-back direction within the formation range of the retainer body 61 in the front-to-back direction. The front surface of the locking body 68c serves as a locking surface 68d arranged in the up-down direction and the left-right direction. Figure 5 As shown in FIG. 6 , the stopper surface 68 d is formed to extend longer in the vertical direction than in the horizontal direction. Figure 8 As shown, the locking surface 68d of the locking body 68c faces the locked surface 17s of the flange portion 17 of the terminal 11, and the terminal 11 is restricted from being pulled out of the cavities 31 and 32 at one time. Figure 5 As shown, a curved surface portion 68e having an arc shape in a front view is formed on the inner surface (the top end surface in the protruding direction) of each locking body 68c.

[0038] (Function of connector 10) Next, the assembly of the connector 10 will be described. First, the retainer 60 is inserted into the assembly holes 34 and 35 of the housing body 33 from below. Figure 8 As shown in the figure, the top end of the arm portion 68b of each primary locking portion 68 is inserted into each end assembly hole 35 of the shell body 33 to avoid interference with the shell body 33. The retainer 60 is retained in the temporary locking position relative to the shell 30 by a temporary locking structure not shown in the figure. In the temporary locking position, the lower end of the retainer body 61 is configured to protrude further downward than the lower surface of the shell body 33. Moreover, in the temporary locking position, as shown in the figure, Fig. 9 As shown, the locking body 68c of each primary locking portion 68 is protrudingly arranged in the terminal insertion passage (as a passage for inserting the terminal 11, in Fig. 9 In contrast, the secondary locking portion 66 does not protrude but is arranged in a retreated manner in the terminal insertion passage of the main body assembly hole 34.

[0039] When the retainer 60 is located at the temporary locking position, the terminal 11 is inserted into the cavities 31 and 32 of the housing 30 from the rear. The front end of the terminal 11 passes through the terminal insertion channel of the main body assembly hole 34 from the rear cavity 32 and is inserted into the front cavity 31. When the front end of the terminal 11 passes through the main body assembly hole 34, the ends on the left and right sides of each flange portion 17 and 18 interfere with the locking body 68c of each primary locking portion 68. As a result, each primary locking portion 68 is elastically deformed to the outside in the left and right direction (the side of the arm portion 68b close to the side wall portion 67), allowing the insertion action of the terminal 11.

[0040] like Figure 8 As shown, the front end of the terminal 11 moves toward the front cavity 31, and the front flange 17 interferes with the stop surface 38, thereby limiting the further insertion of the terminal 11. At the same time, each primary stopper 68 elastically recovers, and the stopper body 68c is embedded between each flange 17, 18. Fig. 9 As shown in FIG. 1 , the curved surface portion 68e of the locking body 68c of each primary locking portion 68 is arranged to be parallel to and opposite to the outer peripheral surface of the outer conductor 12 between the flange portions 17 and 18. Figure 8 As shown in FIG. 1 , the locking surface 68d of the locking body 68c of each primary locking portion 68 is opposed to the locked surface 17s of the front flange portion 17 in a contactable manner. As a result, the terminal 11 is locked to each primary locking portion 68, and the terminal 11 is restricted from being pulled out from the cavity 31, 32 to the rear. In addition, in the temporary locking position, as shown in FIG. Fig. 9 As shown, the outer peripheral surface of the upper side of each flange portion 17 , 18 is arranged along the inner upper surface 42 of the main body mounting hole 34 .

[0041] After the terminal 11 is inserted into the cavity 31, 32, the retainer 60 is pushed up toward the formal locking position. The retainer 60 is retained at the formal locking position relative to the housing 30 by a formal locking structure (not shown). Figure 2 As shown in FIG. 1 , the retainer body 61 is entirely received in the body assembly hole 34. Each primary locking portion 68 moves upward as the retainer 60 is pushed up, but in the formal locking position, it also maintains a state of being locked with the front flange portion 17. Specifically, as shown in FIG. Fig.10As shown, the lower locking surface 68d of the locking body 68c of each primary locking portion 68 is maintained in a state of being opposed to the upper part of the locked surface 17s of the front flange portion 17. Therefore, the locking margin between the locked surface 17s of the terminal 11 at the formal locking position and the locking surface 68d of the retaining member 60 is smaller than the locking margin between the locked surface 17s of the terminal 11 at the temporary locking position and the locking surface 68d of the retaining member 60, but is not zero.

[0042] In addition, if the retaining member 60 reaches the formal locking position, Fig.11 As shown in FIG. 1 , the front receiving surface 62 is disposed oppositely along the outer circumference of the outer conductor 12 between the flanges 17 and 18, and the rear receiving surface 63 is disposed oppositely along the outer circumference of the rear flange 18. Here, the upper ribs 43 and the lower ribs 41 are disposed on the outer circumference of the front flange 17 in a manner of contacting each other at intervals in the circumferential direction. Fig. 9 The upper ribs 43 are shown in contact with each other. In addition, the upper ribs 43 and the retainer side ribs 65 (not shown) are arranged on the outer peripheral surface of the rear flange portion 18 in a manner of contacting each other at intervals in the circumferential direction. Thus, the terminal 11 is arranged in a state of being positioned in the terminal insertion passage of the main body assembly hole 34.

[0043] In addition, if the retaining member 60 reaches the formal locking position, Fig.10 and Fig.11 As shown, the secondary locking portion 66 is opposed to the lower part of the locked surface 17s in the front flange portion 17 in a contactable manner. As a result, the terminal 11 is locked to the secondary locking portion 66, and the withdrawal from the cavity 31, 32 to the rear is restricted for the second time. In addition, in the formal locking position, the step surface 64 is opposed to the front surface of the front flange portion 17 in a contactable manner, restricting the movement of the terminal 11 forward together with the stop surface 38.

[0044] In addition, when the terminal 11 is pulled out from the cavity 31, 32 for maintenance or the like, the retainer 60 is first pulled down to the temporary locking position. Then, a pin-shaped clamp (not shown) is inserted from the front through each opening 44 of the housing 30, and each primary locking portion 68 is elastically deformed outward by the clamp to release the locking of each primary locking portion 68 and the terminal 11. In this state, the terminal 11 can be pulled out backward, thereby removing the terminal 11 from the housing 30.

[0045] As described above, in the case of the first embodiment, the elastically deformable primary locking portion 68 and the fixed-shape secondary locking portion 66 are formed centrally on the retainer 60. Thus, the structure corresponding to the primary locking portion 68 can be omitted from the housing 30, and the structure of the housing 30 can be simplified accordingly. In particular, in the case of the first embodiment, the primary locking portion 68 can also lock the terminal 11 at the formal locking position. Therefore, the stability of the locking state of the primary locking portion 68 and the secondary locking portion 66 relative to the terminal 11 can be improved.

[0046] In addition, the locking margin of the primary locking portion 68 and the terminal 11 at the formal locking position is smaller than the locking margin of the primary locking portion 68 and the terminal 11 at the temporary locking position. In this way, there is no need to change the shape of the terminal 11 according to the primary locking portion 68, so the shape of the terminal 11 can be avoided from being complicated.

[0047] In addition, the primary locking portion 68 has a locking surface 68d extending in the moving direction from the temporary locking position toward the formal locking position, that is, in the up-down direction, and facing the terminal 11 at each position of the temporary locking position and the formal locking position. Since the locking surface 68d of the retainer 60 faces the terminal 11 at each position of the temporary locking position and the formal locking position, and is not formed to correspond to each position independently, the structure of the primary locking portion 68 can be simplified.

[0048] Furthermore, in the case of the first embodiment, the primary locking portions 68 are formed in pairs on both sides of the secondary locking portion 66 in the left-right direction. Accordingly, the stability of the locking state of the primary locking portion 68 with respect to the terminal 11 can be further improved. In particular, even if the primary locking portion 68 reduces the locking margin at the formal locking position, the reduction in the locking margin can be supplemented by the paired primary locking portions 68.

[0049] <Implementation Method 2> In the connector 10A of the second embodiment of the present disclosure, as Figure 12 to Figure 15 As shown, the terminal 11A and the retainer 60A are formed into shapes different from the terminal 11 and the retainer 60 of the above-mentioned embodiment 1, and the housing 30 is formed into the same shape as the housing 30 of the above-mentioned embodiment 1. In addition, in this embodiment 2, the same reference numerals are marked for the same or equivalent structures as those in the above-mentioned embodiment 1. In addition, the structural description of the terminal 11A and the retainer 60A is centered on the parts that are different from the structures in the above-mentioned embodiment 1.

[0050] like Fig.12 As shown, the terminal 11A is a coaxial terminal and includes an outer conductor 12 , an inner conductor 13 , and a dielectric 14 , similarly to the first embodiment. Each elastic contact portion 16A is formed by bending and raising the inner portion of the square U-shaped cutout formed at the front end of the outer conductor 12. The front flange portion 17A of the front and rear flange portions 17A and 18A is wider in the front-to-rear direction than the rear flange portion 18A. A flat surface 19 is formed on the outer peripheral surface of the outer conductor 12 including the rear flange portion 18A. At the position of the flat surface 19, the cross section of the outer conductor 12 is D-shaped.

The upper surface of the holder body 61A is provided with a curved concave frontmost receiving surface 69 at a position forward of the front receiving surface 62. The frontmost receiving surface 69 is arranged at a position lower than the front receiving surface 62. A secondary locking portion 66A is formed as a surface vertical in the up-down direction between the front receiving surface 62 and the frontmost receiving surface 69. That is, the secondary locking portion 66A is formed at a portion above the frontmost receiving surface 69.

[0052] In each primary locking portion 68A, the formation position of the locking body 68c in the arm portion 68b is different from that of each primary locking portion 68 in the above-mentioned embodiment 1. That is, the locking body 68c is protrudingly provided at the central position (center) of the middle part of the arm portion 68b in the front-back direction, or at a position protrudingly provided behind the central position.

[0053] When the retainer 60A is located at the temporary locking position and the formal locking position, the locking surface 68d of the locking body 68c locks the locked surface 17s of the flange portion 17A of the terminal 11A, similar to the first embodiment, to restrict the terminal 11A from being pulled out backward from the cavity 31, 32.

[0054] like Fig.14 As shown, the locking position of the locking surface 68d with respect to the locked surface 17s of the flange portion 17A is set to be smaller than the locking position of the locking surface 68d in the first embodiment (see Figure 8 ) is located at the rear. Fig.15 As shown, when the retainer 60A is located at the formal locking position, the secondary locking portion 66A faces the locked surface 17s of the front flange portion 17A, and the frontmost receiving surface 69 is arranged to face the outer peripheral surface of the front flange portion 17A. In addition, the housing 30 has the same shape as the housing 30 of the first embodiment, but is colored in a different color from the housing 30 of the first embodiment.
