Description

TECHNICAL FIELD

[0001] The present disclosure relates to a connector. BACKGROUND

[0002] Conventionally, a connector described in Japanese Patent Application Publication No. 2008-016261 (Patent Document 1) is known. The connector described in Patent Document 1 is provided with a housing having a cavity in which a terminal member is accommodated, and a front stopper selectively held in a temporary locking position and a formal locking position with respect to the housing. When the front stopper is held in the temporary locking position, insertion and extraction of the terminal member with respect to the housing is permitted, and when the front stopper is held in the formal locking position, extraction of the terminal member inserted into the housing is inhibited. By pushing a front wall of the front stopper in a direction approaching the housing, the front stopper can be moved from the temporary locking position to the formal locking position.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2008-016261 SUMMARY

[0006] PROBLEMS TO BE SOLVED BY THE INVENTION

[0007] In the above-described structure, the direction in which the front stopper is moved from the temporary locking position to the formal locking position coincides with the fitting direction of the connector. In such a case, even in a state where the front stopper is held in the temporary locking position, fitting of the connector and an opposite-side connector that is a fitting counterpart of the connector can be permitted.

[0008] SOLUTIONS TO THE PROBLEMS

[0009] The connector of the present disclosure includes a female connector and a male connector fitted into the inside of the female connector. The female connector includes a female housing having a cover portion opened on one side in a fitting direction, a female terminal receiving portion in which a female terminal is received, and a front stopper movable relative to the female housing between a temporary stop position and a formal stop position in the fitting direction. In the temporary stop position, elastic deformation of a lance-shaped portion provided in the female terminal receiving portion is allowed by the front stopper, so that the female terminal can be inserted into the female terminal receiving portion. In the formal stop position, elastic deformation of the lance-shaped portion is inhibited by the front stopper, so that the female terminal is retained in the female terminal receiving portion. The female housing includes a stop portion elastically deformable in a direction intersecting the fitting direction. The male connector includes an abutting portion extending in the fitting direction and abutting against the stop portion. The front stopper includes a stop release portion engaged with the stop portion. In a state where the front stopper is retained in the temporary stop position, the abutting portion is abutted against the stop portion, so that fitting of the male connector and the female connector is inhibited. In a state where the front stopper is retained in the formal stop position, the stop release portion is engaged with the stop portion, and the stop portion is elastically deformed, so that the stop portion is configured not to abut against a tip end portion of the abutting portion, and fitting of the male connector and the female connector is allowed.

[0010] Effects of Invention

[0011] According to the present disclosure, a connector in which fitting is inhibited in a state where a front stopper is retained in a temporary stop position can be provided. BRIEF DESCRIPTION OF DRAWINGS

An elastic contact piece (not shown) is provided inside the connection tube portion 33. The male terminal 64 is inserted into the inside of the connection tube portion 33 and comes into contact with the elastic contact piece (not shown), whereby the male terminal 64 and the female terminal 32 are electrically connected. The wire crimping portion 34 has a core wire crimping portion 34A that crimps the core wire of the electric wire W1 and an insulating covering portion crimping portion 34B that crimps the insulating covering portion of the electric wire W1.

[0049] [Spear-shaped portion]

[0050] As shown, Figure 5 and Figure 7 As shown, a spear-shaped portion 35 that protrudes in a cantilever shape toward the front and an elastic deformation allowance space 36 that allows elastic deformation of the spear-shaped portion 35 to the outside (lower side or upper side) of the female terminal housing portion 31 are provided in the lower wall or the upper wall of the female terminal housing portion 31. As shown, Figure 13 In a state where the female terminal 32 is housed in the female terminal housing portion 31, the spear-shaped portion 35 is disposed so as to be caught by a spear-shaped portion receiving portion 37 provided to the connection tube portion 33 of the female terminal 32.

[0051] As shown, Figure 11As shown, a sealing member storage section 39 for storing a waterproof sealing member 38 is provided behind the female terminal storage section 31. The sealing member 38 is made of an elastic material such as rubber. A sealing insertion hole (not shown) for inserting the wire W1 is formed in the sealing member 38. A cover-shaped rear retainer 40 is fitted to the rear of the sealing member storage section 39. The rear retainer 40 has an insertion hole 40A for inserting the power supply wire W1, blocking the sealing member storage section 39 from the rear to prevent the sealing member 38 from detaching from the sealing member storage section 39.

[0052] [Stop part, recessed part]

[0053] like Figure 11 As shown, the abutment portion housing portion 41, like the female terminal housing portion 31, is formed by the inner wall of a hole through which the female housing body 22 passes in the front-rear direction. The abutment portion housing portion 41 houses the abutment portion 69 of the male connector 60. Figure 5 The lower wall of the abutment receiving portion 41 shown is provided with a stop portion 42 that protrudes forward in a cantilever shape. The stop portion 42 can elastically deform downwards (in an example, in a direction intersecting the engagement direction). Figure 6 As shown, the front half of the stop 42 has different shapes on the left and right. The left side of the stop 42 is formed as a recessed portion 43 that is concave downwards, and the right side of the stop 42 is formed as a mountain-shaped engaging portion 44 that protrudes upwards from the recessed portion 43. Figure 7 The abutment portion 41 and the stop portion 42 shown are configured to be vertically and horizontally aligned with each other. Figure 5 (and Figure 6 The abutment portion 41 and the stop portion 42 shown are opposite. That is, Figure 7 The stop portion 42 shown is provided on the upper wall of the abutment portion receiving portion 41 and can be elastically deformed upward (in an example of a direction intersecting the fitting direction). Figure 7 The right side of the stop portion 42 shown is formed as an upwardly recessed recess 43, and the left side of the stop portion 42 is formed as a mountain-shaped engaging portion 44 that protrudes downwardly from the recess 43.

[0054] [Front stopper, stopper release part]

[0055] The front stop 50 is made of insulating synthetic resin, such as Figure 3 and Figure 4 As shown, it has a front wall portion 51, a peripheral wall portion 52 protruding rearward from the outer periphery of the front wall portion 51, and a plurality of through holes 53 formed through the front wall portion 51 in the front-rear direction. A plurality of elastic deformation suppression portions 54 and two stop release portions 55 are formed extending rearward from the front wall portion 51. Figure 4 As shown, an inclined surface 55A is provided at the rear end of the stop release part 55.

[0056] likeFigure 3 As shown, the upper side first locking piece 56A and the lower side first locking piece 56B are provided at the upper and lower portions of the right side of the front wall portion 51. The upper side second locking piece 56C and the lower side second locking piece 56D are provided at the upper and lower portions of the left side of the front wall portion 51. The left and right direction dimensions of the upper side second locking piece 56C and the lower side second locking piece 56D are smaller than the left and right direction dimensions of the upper side first locking piece 56A and the lower side first locking piece 56B. As shown in FIG. 6, the upper side first locking piece 56A and the lower side first locking piece 56B are provided with a provisional locking protrusion 57 and a formal locking protrusion 58 disposed further forward than the provisional locking protrusion 57. The rear side portions of the provisional locking protrusion 57 and the formal locking protrusion 58 are formed as inclined surfaces 57A, 58A, which are tapered, and located further inward as they go forward. The front end surfaces 57B, 58B of the provisional locking protrusion 57 and the formal locking protrusion 58 are perpendicular to the fitting direction (front and rear direction).

Figure 4 As shown, the upper side first locking piece 56A and the lower side first locking piece 56B are provided with a provisional locking protrusion 57 and a formal locking protrusion 58 disposed further forward than the provisional locking protrusion 57. The rear side portions of the provisional locking protrusion 57 and the formal locking protrusion 58 are formed as inclined surfaces 57A, 58A, which are tapered, and located further inward as they go forward. The front end surfaces 57B, 58B of the provisional locking protrusion 57 and the formal locking protrusion 58 are perpendicular to the fitting direction (front and rear direction). As shown in FIG. 7, the upper side second locking piece 56C is formed with the formal locking protrusion 58, and the lower side second locking piece 56D is formed with the provisional locking protrusion 57. Figure 3 As shown, the upper side first locking piece 56A and the lower side first locking piece 56B are provided with a provisional locking protrusion 57 and a formal locking protrusion 58 disposed further forward than the provisional locking protrusion 57. The rear side portions of the provisional locking protrusion 57 and the formal locking protrusion 58 are formed as inclined surfaces 57A, 58A, which are tapered, and located further inward as they go forward. The front end surfaces 57B, 58B of the provisional locking protrusion 57 and the formal locking protrusion 58 are perpendicular to the fitting direction (front and rear direction). As shown in FIG. 7, the upper side second locking piece 56C is formed with the formal locking protrusion 58, and the lower side second locking piece 56D is formed with the provisional locking protrusion 57.

[0057] As shown, the upper side first locking piece 56A and the lower side first locking piece 56B are provided with a provisional locking protrusion 57 and a formal locking protrusion 58 disposed further forward than the provisional locking protrusion 57. The rear side portions of the provisional locking protrusion 57 and the formal locking protrusion 58 are formed as inclined surfaces 57A, 58A, which are tapered, and located further inward as they go forward. The front end surfaces 57B, 58B of the provisional locking protrusion 57 and the formal locking protrusion 58 are perpendicular to the fitting direction (front and rear direction). As shown in FIG. 7, the upper side second locking piece 56C is formed with the formal locking protrusion 58, and the lower side second locking piece 56D is formed with the provisional locking protrusion 57. Figures 8 to 10 As shown, the upper side first locking piece 56A and the lower side first locking piece 56B are provided with a provisional locking protrusion 57 and a formal locking protrusion 58 disposed further forward than the provisional locking protrusion 57. The rear side portions of the provisional locking protrusion 57 and the formal locking protrusion 58 are formed as inclined surfaces 57A, 58A, which are tapered, and located further inward as they go forward. The front end surfaces 57B, 58B of the provisional locking protrusion 57 and the formal locking protrusion 58 are perpendicular to the fitting direction (front and rear direction). As shown in FIG. 7, the upper side second locking piece 56C is formed with the formal locking protrusion 58, and the lower side second locking piece 56D is formed with the provisional locking protrusion 57.

[0058] [Provisional locking position]

[0059] When the front stopper body 50 is pushed against the female housing body 22, first, the inclined surface 57A of the provisional locking protrusion 57 and the inclined surface 47A of the locking portion 47 are engaged (omitted from the drawing). When the front stopper body 50 is further pushed against the female housing body 22, the provisional locking protrusion 57 passes over the locking portion 47, and the inclined surface 58A of the formal locking protrusion 58 and the inclined surface 47A of the locking portion 47 are engaged (refer to FIG. 8). Figure 8 Figure 8 Figure 9 ​​The position of the front stopper 50 shown with respect to the female housing body 22 is formed into a temporary locking position. When the front stopper 50 is located in the temporary locking position, as shown Figure 9 The front stopper 50 is locked by the front end surface 57B of the temporary locking protrusion 57 and the locking surface 47B of the locking portion 47, and thus the front stopper 50 is not easily separated from the female housing body 22, and the front stopper 50 is maintained in the temporary locking position.

[0060] [Formal locking position]

[0061] When the front stopper 50 is further pressed toward the female housing body 22 from the temporary locking position, the inclined surface 58A of the formal locking protrusion 58 and the inclined surface 47A of the locking portion 47 are engaged, and the formal locking protrusion 58 crosses the locking portion 47. The front stopper 50 is pressed toward the female housing body 22 until the front wall portion 51 of the front stopper 50 abuts against the front surface of the female housing body 22 (see Figure 10 ). Figure 10 The position of the front stopper 50 shown with respect to the female housing body 22 is formed into a formal locking position. When the front stopper 50 is located in the formal locking position, the front end surface 58B of the formal locking protrusion 58 and the locking surface 47B of the locking portion 47 are disposed in opposition to each other and are capable of locking. Thus, the front stopper 50 is not easily separated from the female housing body 22, and the front stopper 50 is maintained in the formal locking position.

[0062] As shown Figure 13 , the elastic deformation suppression portion 54 of the front stopper 50 is disposed outside the elastic deformation permissible space 36 of the female terminal receiving portion 31 in a state in which the front stopper 50 is maintained in the temporary locking position, and thus elastic deformation of the lance portion 35 is permitted, and the female terminal 32 can be inserted into the female terminal receiving portion 31. As shown Figure 12 , in a state in which the front stopper 50 is maintained in the formal locking position, the elastic deformation suppression portion 54 is received in the elastic deformation permissible space 36, and thus elastic deformation of the lance portion 35 can be suppressed, and the locking of the lance portion 35 and the lance portion receiving portion 37 of the female terminal 32 is not released. Thus, the female terminal 32 is maintained in the female terminal receiving portion 31.

[0063] As shown Figure 5 , the stop release portion 55 of the front stopper 50 is disposed in front of the stop portion 42 in a state in which the front stopper 50 is maintained in the temporary locking position, and does not engage with the stop portion 42. When the front stopper 50 is moved rearward from the temporary locking position, the stop release portion 55 begins to engage with the locking portion 44 of the stop portion 42. The rear end portion of the stop release portion 55 is formed as an inclined surface 55A, and thus begins to smoothly engage with the mountain-shaped locking portion 44. When the front stopper 50 is further moved rearward to reach the formal locking position, as shown Figure 12As shown, the stop release part 55 engages with the engagement part 44 of the stop part 42 at a position forward of the inclined surface 55A, causing the stop part 42 to elastically deform outward. That is, the front portion of the abutment portion receiving part 41 of the stop part 42 expands through the stop release part 55.

[0064] [Male Connector]

[0065] like Figure 17 As shown, the male connector 60 is configured to have a male housing 61 and a male front stop 71 that can be moved in the front-rear direction and held in the male housing 61.

[0066] The anode housing 61 is made of insulating synthetic resin, such as... Figure 11 As shown, it includes a male housing body 62 and a male cover portion 63 that covers the male housing body 62 and has an opening at the rear. Figure 16 As shown, a cam pin 63A is provided protruding outward on the side of the male cover portion 63. A locking part 63B is provided at the front end of the upper wall of the male cover portion 63, which engages with the locking arm 27 and the locking receiving part 28 of the female connector 20 (see reference). Figure 11 ).

[0067] like Figure 17 As shown, the male housing body 62 has multiple male terminal receiving portions 65, which house male terminals 64 connected to the wire W2. Detailed descriptions are omitted, but similar to the female connector 20, a male front stop 71 is mounted to the male housing body 62 and positioned in the fully locked position, thereby suppressing elastic deformation of the spear-shaped portion 66 and retaining the male terminal 64 in the male terminal receiving portion 65. Additionally, the male connector 60 is provided with a sealing member 67 for the power supply wire W2 to be inserted, a rear retainer 68, etc. Hereinafter, it is assumed that only the state where the male front stop 71 is held in the fully locked position is considered.

[0068] [Abutting part, tip of the abutting part, abutting surface]

[0069] like Figure 13 As shown, the male housing body 62 has a rearwardly extending and convex abutment portion 69. The abutment portion 69 is positioned corresponding to the abutment portion receiving portion 41 of the female housing body 22. Figure 17 As shown, the top end 70 of the abutment portion 69 has a tapered abutment surface 70A, which is formed into a sharp shape with an acute angle. The top end 70 of the abutment portion 69 abuts against the stop portion 42 when the front stop body 50 is held in a temporary locking position.

[0070] like Figure 1As shown, the male anterior stop 71 has a rearwardly protruding square protrusion 72 and an H-shaped protrusion 73. The square protrusion 72 and the H-shaped protrusion 73 are respectively housed in the square protrusion housing portion 45 and the H-shaped protrusion housing portion 46 of the female housing body 22 (see reference). Figure 13 By providing square protrusions 72 and H-shaped protrusions 73, the connector 10 is prevented from becoming too tight.

[0071] [Connector engagement with the front stop in a temporarily locked position]

[0072] like Figure 15 As shown, with the front stop 50 of the female connector 20 held in a temporary locked position, when the cover 23 of the female connector 20 is inserted into the male connector 60, the recess 43 of the stop 42 abuts against the abutment surface 70A, receiving the top end 70 of the abutment portion 69. Therefore, the male connector 60 cannot be further inserted into the cover 23, thus suppressing the engagement of the male connector 60 and the female connector 20. Furthermore, in the locked state between the recess 43 and the top end 70 of the abutment portion 69, as... Figure 12 As shown, the cam pin 63A is configured such that it does not fully enter the cam groove 25B of the rod 24. As a result, the connector 10 cannot be forcibly engaged by rotating the rod 24.

[0073] [Connector engagement with the front stop in the fully engaged position]

[0074] On the other hand, with the front stop 50 held in the fully engaged position, such as Figure 11 As shown, the stop release part 55 engages with the stop part 42, and the stop part 42 elastically deforms. Therefore, the stop part 42 is configured not to abut against the tip 70 of the abutment part 69, and the abutment part 69 can be housed in the abutment part housing part 41. Thus, the male connector 60 and the female connector 20 can be properly engaged (see reference). ​ ).

[0075] [Effects of the Implementation Method]

[0076] According to this implementation method, the following functions and effects are achieved.

[0077] The connector 10 of the present embodiment includes the female connector 20 and the male connector 60 fitted into the inside of the female connector 20. The female connector 20 includes a female housing 21 including a cover portion 23 opened in the front direction, a female terminal 32 housed in a female terminal housing portion 31 in the inside of the female housing 21, and a front stopper 50 movable in the front-rear direction with respect to the female housing 21 between a temporary stop position and a formal stop position. In the temporary stop position, elastic deformation of a lance-shaped portion 35 provided to the female terminal housing portion 31 is allowed by the front stopper 50, so that the female terminal 32 can be inserted into the female terminal housing portion 31. In the formal stop position, elastic deformation of the lance-shaped portion 35 is suppressed by the front stopper 50, so that the female terminal 32 is held to the female terminal housing portion 31. The female housing 21 includes a stop portion 42 elastically deformable in the up-down direction. The male connector 60 includes an abutting portion 69 extending in the front-rear direction and abutting against the stop portion 42. The front stopper 50 includes a stop release portion 55 engaged with the stop portion 42. In a state where the front stopper 50 is held to the temporary stop position, abutting of a tip end portion 70 of the abutting portion 69 against the stop portion 42 is allowed, so that fitting of the male connector 60 and the female connector 20 is suppressed. In a state where the front stopper 50 is held to the formal stop position, the stop release portion 55 is engaged with the stop portion 42, and the stop portion 42 is elastically deformed, so that the stop portion 42 is disposed not to abut against the tip end portion 70 of the abutting portion 69, and fitting of the male connector 60 and the female connector 20 is allowed.

[0078] According to the above-described structure, in the state where the front stopper 50 is held to the temporary stop position, fitting of the male connector 60 and the female connector 20 can be suppressed.

[0079] In the present embodiment, the tip end portion 70 of the abutting portion 69 has a tapered abutting surface 70A formed in a sharp shape, and the stop portion 42 has a recessed portion 43 abutting against the abutting surface 70A in the state where the front stopper 50 is held to the temporary stop position, and receiving the tip end portion 70 of the abutting portion 69.

[0080] According to the above-described structure, in the state where the front stopper 50 is held to the temporary stop position, the engagement force of the abutting portion 69 and the stop portion 42 can be increased, so that fitting of the male connector 60 and the female connector 20 can be further easily suppressed.
