Description

[Technical field]

[0001] The present invention relates to a connector and a method for removing a terminal from the connector. [Background technology]

[0002] Conventionally, connectors have been proposed that include a terminal and a housing having a terminal accommodating chamber (also called a "cavity"). In conventional connectors, a locking lance is provided in the terminal accommodating chamber, and when the terminal is inserted to a predetermined position in the terminal accommodating chamber, the terminal is locked by the locking lance and prevented from falling out of the terminal accommodating chamber. On the other hand, when the terminal is to be removed from the terminal accommodating chamber, a jig is used to release the lock between the terminal and the locking lance. As an example, the lock between the terminal and the locking lance is released by inserting and operating the jig into the terminal accommodating chamber, and the terminal is removed from the terminal accommodating chamber by pulling out the terminal in this state (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-247227 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the connector of Patent Document 1, the terminal is removed from the terminal receiving chamber by inserting a jig into the space between the terminal and the locking lance to a predetermined position, dislodging the locking lance to release the lock with the terminal, and then pressing the terminal with the jig to move it back. Although this makes it easy to remove the terminal from the terminal receiving chamber, there is a risk that the terminal surface may be scraped by contact between the terminal and the jig, resulting in the generation of shavings, etc. If the shavings, etc. generated in this way adhere to the terminal, this may cause poor electrical continuity with the mating terminal or a decrease in the waterproof performance of the terminal.

[0013] <Embodiment> Hereinafter, a connector 1 according to one embodiment of the present invention and a method for removing a terminal from the connector 1 will be described with reference to the drawings.

[0014] For the sake of convenience, the following definitions are used for the terms "front", "rear", "left", "right", "upper" and "lower" as shown in Figs. 1 to 10. The "front-rear direction", "left-right direction" and "up-down direction" are mutually orthogonal. The front-rear direction corresponds to the "insertion direction" of the present invention.

[0015] <Outline of Connector 1 Configuration> The schematic configuration of connector 1 will be described below with reference to Fig. 1. Connector 1 comprises a cylindrical housing 2, a side retainer 3 attached to housing 2, a mating detection member 4 slidably attached to the outer surface of housing 2, terminals 51 (female terminals in this example) accommodated in housing 2, and an annular seal member 6 attached to housing 2. In this example, connector 1 is a female connector configured to be matable with a mating connector (male connector, not shown) along the front-rear direction.

[0016] <Housing 2> The housing 2 will be described below with reference to Figures 2 to 4 and 6. The housing 2 is made of synthetic resin and integrally comprises a cylindrical housing main body 11 and a cylindrical hood portion 12 that covers the outer circumferential surface of the housing main body 11 with a gap therebetween (see Figures 2 to 4 and 6). A housing of a mating connector (not shown, also referred to as "mating housing") is inserted into the gap between the outer circumferential surface of the housing main body 11 and the inner circumferential surface of the hood portion 12.

[0017] The housing body 11 is formed with a plurality (three in this example) of terminal accommodating chambers 13 into which a plurality (three in this example) of terminals 51 (terminal-attached electric wires 5) are respectively inserted from the rear. Each of the terminal accommodating chambers 13 is open to the outside through an opening at the front end of the housing body 11, and a terminal (not shown, a male terminal also referred to as a "mating terminal") of a mating connector is inserted from this opening.

[0018] The housing body 11 is formed so as to protrude forward beyond the front end surface of the hood portion 12, and a seal member 6 is attached to the cylindrical outer peripheral surface of the housing body 11 covered by the hood portion 12. The housing body 11 has a side retainer 3 attached to the outer peripheral surface of a substantially rectangular semi-cylindrical front end portion 14 protruding forward from the hood portion 12.

[0019] The housing 2 is formed with a cantilever-shaped locking lance 15 that extends forward and is elastically deformable in the vertical direction so as to face the inside of the terminal accommodating chamber 13 from below (see Figs. 3 and 6). The locking lance 15 locks the terminal 51 inserted into the terminal accommodating chamber 13 (see Figs. 6 to 9). A jig hook 15a that protrudes forward is provided at the lower end of the front end of the locking lance 15, against which the jig 7 comes into contact when the lock with the terminal 51 is released (see Figs. 7 to 8).

[0020] A locking mechanism 20 is provided on the upper outer surface (top surface) of the housing 2 (see Figs. 1 to 2 and 4). The locking mechanism 20 has an elastically deformable locking arm 21 and an elastically deformable release arm 24 (see Fig. 4).

[0021] The lock arm 21 is formed in a substantially rectangular U-shape, is supported in a cantilever manner on the upper surface of the housing 2, and integrally includes a pair of left and right elastic arm pieces 22 extending forward substantially parallel to the upper surface of the housing 2, and a locking piece 23 bridging the front ends of the elastic arm pieces 22 in the left-right direction (see Figs. 4 and 6). The locking piece 23 locks with a locking portion (not shown) of the mating housing when the connector 1 and the mating connector are fully mated.

[0022] The lock arm 21 is supported in a cantilever manner at the front ends of a pair of elastic arm pieces 22, and is connected to a release arm 24 having a substantially rectangular U-shape extending rearward (see FIGS. 4 and 6).

[0023] The release arm 24 has an unlocking operation portion 25 that is pressed down when the locking piece 23 is released from the locking portion of the mating housing (see Figs. 4 and 6). The unlocking operation portion 25 is spaced apart from the housing 2 in the up-down direction and is disposed above the elastic arm piece 22. When the unlocking operation portion 25 is pressed down and displaced downward, an upward unlocking force is applied to the locking piece 23 via the release arm 24.

[0024] The housing 2 is provided with a pair of protective walls 16 that sandwich the lock arm 21 in the left-right direction (see Figs. 2 to 4). The pair of protective walls 16 are erected on the upper part of the hood portion 12 to protect the lock mechanism 20. A beam portion 17 is provided in front of the protective walls 16 (see Figs. 2 to 4). Both left-right ends of the beam portion 17 are connected to the protective walls 16 and are disposed with a gap between them and the hood portion 12.

[0025] On both left and right side surfaces of the release arm 24, there are provided locked projections 26 that protrude toward the opposing protective wall portion 16 (see FIG. 4). A locking projection 43 of the fitting detection member 4, which will be described later, is locked to the locked projections 26.

[0026] An upwardly protruding restriction rib 18 is provided on the upper surface at the rear end of the housing body 11, approximately in the center in the left-right direction so as to extend in the front-rear direction (see FIG. 4). The protruding height (vertical length) of the restriction rib 18 is set so that the release operation part 25 is not pushed down more than necessary.

[0027] <Side retainer 3> The side retainer 3 will be described below with reference to Fig. 2 and Figs. 5-6. The side retainer 3 is made of synthetic resin and integrally comprises a retainer body 31 having a generally U-shaped cross section that opens to the left, and a retainer front plate portion 32 that closes the front end opening of the retainer body 31 (see Figs. 2 and 5). The retainer front plate portion 32 is formed with a plurality of insertion openings 33 (three in this example) corresponding to the plurality of terminal accommodating chambers 13. When the side retainer 3 is attached to the housing 2, the insertion openings 33 communicate with the terminal accommodating chambers 13 (see Fig. 1), and the mating terminals are inserted into them.

[0028] The retainer body 31 is integrally formed with a retainer upper surface portion 34 (see FIG. 2) and a retainer lower surface portion 35 (see FIG. 5) which are spaced apart in the vertical direction and face each other, and a retainer curved surface portion 36 (see FIG. 2) which connects the right end edge of the retainer upper surface portion 34 with the right end edge of the retainer lower surface portion 35. A rib-shaped retainer protrusion (reference number omitted) which extends in the front-rear direction is provided downwardly on the left end edge of the retainer upper surface portion 34.

[0029] A generally rectangular jig insertion opening 37 is provided in the retainer lower surface portion 35 so as to penetrate in the vertical direction (see Figs. 5 to 8). In the connector 1, the terminal accommodating chamber 13 communicates with the outside through the jig insertion opening 37, and a jig 7 for removing a terminal is inserted into the terminal accommodating chamber 13 through the jig insertion opening 37. Since the side retainer 3 opens to the left, the left jig insertion opening 37a is formed in a generally rectangular U-shape.

[0030] A guide portion 38 that guides the jig 7 inserted into the jig insertion port 37 to the jig hanging portion 15a of the locking lance 15 is provided at the front end of the jig insertion port 37 so as to extend in the front-rear direction (see Figs. 5 to 8). The guide portion 38 is formed in an inclined shape that rises from the front to the rear.

[0031] When the side retainer 3 is attached to the front end 14 of the housing main body 11, the opening on the left side of the side retainer 3 is slightly widened, and the front end 14 is inserted into the inside of the side retainer 3 from the opening and moved in the left-right direction. When the side retainer 3 is moved in the left-right direction, the retainer protrusion enters and is locked into a locking groove (reference number omitted) provided in the front end 14, whereby the side retainer 3 is attached to the housing 2. With the side retainer 3 attached to the housing 2, unintended removal (disengagement) of the terminals 51 from the terminal accommodating chambers 13 is suppressed.

[0032] <Fitting detection member 4> The fitting detection member 4 will be described below with reference to Figures 2 and 6. The fitting detection member 4 is made of synthetic resin, is attached to the housing 2 from the rear, and is configured to be slidable in the front-rear direction. The fitting detection member 4 integrally includes a pair of side walls 41 facing each other in the left-right direction, and a support wall 42 bridging the rear ends of the upper ends of the side walls 41 (see Figure 2).

[0033] A locking projection 43 that protrudes toward the opposing side wall 41 is provided on the opposing surface of each side wall 41 (see FIG. 2). When the fitting detection member 4 is in the provisionally locked position, the locking projection 43 is locked to the locked projection 26 of the housing 2. A slide operation portion 44 that is operated when sliding the fitting detection member 4 is provided on the upper end surface of the support wall 42.

[0034] An arm piece 45 extending forward is provided at approximately the center in the left-right direction of the support wall portion 42 (see Figs. 2 and 6). The arm piece 45 is supported by the support wall portion 42 in a cantilevered manner and is formed so as to incline downward. A locking claw 46 extending downward is formed at the front end of the arm piece 45. The arm piece 45 is configured so that the locking claw 46 can swing upward with the rear end portion as a fulcrum and elastically deform. When the fitting detection member 4 is in the temporary locking position, the locking claw 46 abuts against the rear end of the locking piece 23 of the housing 2 (see Fig. 6), and when the fitting detection member 4 is in the full locking position, the locking claw 46 is locked to the locking piece 23 (see Fig. 9).

[0035] <Terminal attached wire 5> The electric wire with terminal 5 will be described below with reference to Fig. 2. The electric wire with terminal 5 has a terminal 51, an electric wire 52 having the terminal 51 connected to a front end thereof, and an annular sealing member 53 attached to the electric wire 52.

[0036] <Assembly procedure for each component that composes the connector 1> The procedure for assembling each of the components constituting the connector 1 will be described below. First, the seal member 6 is attached to the housing 2, and the terminal 51 connected to the electric wire 52 is inserted from the rear into the terminal accommodating chamber 13 of the housing 2. As a result, the terminal 51 is locked into the locking lance 15 of the housing 2. The seal member 53 attached to the electric wire 52 is also received in the rear end of the terminal accommodating chamber 13, thereby making the terminal accommodating chamber 13 waterproof.

[0037] Next, the side retainer 3 is attached to the front end portion 14 of the housing body 11. As a result, the terminals 51 are prevented from coming off by the side retainer 3.

[0038] Next, the fitting detection member 4 is attached to the housing 2 from the rear to the provisionally locked position. At this time, the locking projection 43 of the fitting detection member 4 passes over the locked projection 26 of the housing 2 and is locked thereto, so that the fitting detection member 4 is provisionally locked to the housing 2 (see FIG. 6). This completes the assembly of the components that make up the connector 1, and the connector 1 is completed.

[0039] <Mating procedure between connector 1 and the mating connector> The procedure for fitting the connector 1 to the mating connector will be described below. The connector 1 and the mating connector are fitted together when the fitting detection member 4 is provisionally locked to the housing 2. First, the mating housing is inserted between the outer peripheral surface of the housing body 11 and the inner peripheral surface of the hood portion 12.

[0040] At this time, the locking portion of the mating housing jumps over locking piece 23 of housing 2 from below toward the rear while elastically deforming it, and the locking portion of the mating housing and locking piece 23 are engaged with each other. As a result, locking claw 46 of arm piece 45 of fitting detection member 4 is lifted upward by the locking portion of the mating housing (i.e., arm piece 45 is elastically deformed), and the abutment state of locking claw 46 with the rear end of locking piece 23 is released.

[0041] In this state, when the fitting detection member 4 is pushed forward so as to be displaced to the full locking position, the locking claw 46 passes over the locking piece 23 from above and forward, causing the arm piece 45 to recover from its elastic deformation, and the locking claw 46 and the locking piece 23 are locked together (see FIG. 9). This completes the fitting of the connector 1 with the mating connector. When the fitting of the connector 1 with the mating connector is complete, the mating terminal is inserted into the terminal 51, and the terminal 51 and the mating terminal are electrically connected.

[0042] <Procedure for disengaging connector 1 from the mating connector> The following describes the procedure for disengaging the connector 1 from the mating connector. To disengage the connector 1 from the mating connector, first, the engagement detection member 4 is pulled backward and returned from the full engagement position to the partial engagement position.

[0043] Next, the unlocking operation portion 25 of the locking mechanism 20 in the housing 2 is pressed downward. This causes the unlocking arm 24 to swing and the locking piece 23 of the locking arm 21 to be displaced upward, releasing the lock between the locking piece 23 and the locking portion of the mating housing. In this state, the connector 1 and the mating connector are moved apart, thereby releasing the engagement between the connector 1 and the mating connector.

[0044] If the release operation portion 25 is pressed down more than necessary, it will come into contact with the restricting rib 18 (see FIG. 4) of the housing 2, restricting the swinging of the release arm 24 after the contact. This prevents the lock mechanism 20 from being damaged or broken due to excessive displacement of the release arm 24.

[0045] <How to remove the terminal> A terminal removal method will be described below with reference to Figs. 7 and 8. To remove the terminal 51 from the terminal accommodating chamber 13, it is necessary to release the engagement between the terminal 51 and the locking lance 15 of the housing. First, the jig 7 is inserted from the front into the terminal accommodating chamber 13 through the jig insertion opening 37. The jig 7 is inserted into the terminal accommodating chamber 13 by moving it in the approximately front-rear direction while the jig 7 is in contact with the guide portion 38 (see Fig. 7). This insertion continues until it reaches the jig hook portion 15a of the locking lance 15 in the housing 2.

[0046] When the jig 7 is inserted into the terminal accommodating chamber 13, the guide portion 38 guides the jig 7 to the jig hanging portion 15a (see FIG. 8). When the jig 7 reaches the jig hanging portion 15a, the front end portion (the rear end portion in FIG. 8) of the jig 7 abuts against the jig hanging portion 15a and is disposed between the terminal 51 and the jig hanging portion 15a so as not to come into contact with the terminal 51.

[0047] In this state, by pushing the jig 7 downward, the locking lance 15 is elastically deformed downward. This releases the lock between the terminal 51 and the locking lance 15. In this state, the terminal 51 can be removed (pulled out) from the terminal accommodating chamber 13 by pulling the terminal 51 backward.

[0048] As a result, when the jig 7 is inserted into the terminal accommodating chamber 13, the jig 7 does not interfere with the terminal 51, thereby suppressing malfunctions of the terminal caused by the terminal extraction operation. Furthermore, the terminal extraction operation is excellent in workability because the jig 7 can be simply inserted into the terminal accommodating chamber 13 while being in contact with the guide portion 38. In this way, the connector 1 and the terminal extraction operation method for the connector 1 according to this embodiment suppress malfunctions of the terminal 51 caused by the terminal extraction operation and are excellent in workability.

[0049] <Other forms> The present invention is not limited to the above-described embodiment, and can be appropriately modified, improved, etc. In addition, the material, shape, size, number, arrangement location, etc. of each component in the above-described embodiment are arbitrary as long as the present invention can be achieved, and are not limited.

[0050] In the above embodiment, the restricting rib 18 is provided at approximately the center in the left-right direction at the rear end of the housing body 11 (see FIG. 4), but for example, a pair of restricting ribs 18 may be provided at both left-right ends at the rear end of the housing body 11 (see FIG. 10). Note that even in this case, the protruding height (vertical length) of the restricting rib 18 is set so that the unlocking operation portion 25 is not pushed down more than necessary.
