[0012] (2) The connector can limit or allow the release of the lance's locking.

[0013] (3) The connector described in (2), wherein the retainer moves rearward from the full locking position to the partial locking position.

[0014] (3) In the connector, when the retainer is placed in the temporary engagement position, the visor portion can open the front of the punch hole, making it easy to insert a jig into the punch hole in a direction intersecting the front-to-rear direction.

[0015] (4) A connector described in any one of (1) to (3), wherein the punch hole has a retreat surface forward of the release surface and inclined forward as it approaches the side opening.

[0017] [Details of the embodiment of the present disclosure] <Embodiment 1> A first embodiment of the connector 1 of the present disclosure will be described with reference to Figs. 1 to 8. In the figures, "front", "rear", "upper", "lower", "right side", and "left side" are represented by "F", "B", "U", "D", "R", and "L", respectively. Note that the directional references are defined for convenience, and do not necessarily coincide with the directions when the connector 1 is mounted on a vehicle or the like. For example, the up-down direction is not limited to the direction of gravity.

[0018] [Connector configuration] As shown in FIG. 1, the connector 1 includes a housing 10, a conductive member 11, a female terminal 12 serving as a terminal, and two retainers 13.

[0019] [Housing configuration] The housing 10 is made of synthetic resin. The housing 10 is block-shaped. As shown in FIG. 2, a terminal insertion groove 10A is formed in the front of the housing 10, into which a connecting portion 11A of the conductive member 11, which will be described later, is attached. The terminal insertion groove 10A is formed in two stages, upper and lower, with grooves that are open toward the front and extend laterally. A clamping portion 10J extending in the left-right direction is provided between the upper terminal insertion groove 10A and the lower terminal insertion groove 10A. As shown in FIG. 3, a locked portion 10K is provided at the front end of the clamping portion 10J, protruding upward and downward.

[0020] At the rear of the housing 10, cavities 10B into which female terminals 12, described later, are fitted are divided into upper and lower stages and aligned in the vertical and horizontal directions. The rear end of each cavity 10B opens at the rear end face of the housing 10 as a terminal insertion port 10C. Each cavity 10B is provided with a lance 10D. The lance 10D is formed to extend forward in a cantilever shape and be elastically deformable. The lance 10D is disposed on the upper side of the upper cavity 10B and on the lower side of the lower cavity 10B.

[0021] The front end of each lance 10D is provided with a locking surface 10Q that locks with the female terminal 12 and a release surface 10R that is pressed by a jig G described later to release the lock of the lance 10D with the female terminal 12. In the upper lance 10D, the locking surface 10Q is located on the lower side of the front end of the lance 10D. In the upper lance 10D, the release surface 10R is located on the upper side. In the lower lance 10D, the locking surface 10Q is located on the upper side of the front end of the lance 10D. In the lower lance 10D, the release surface 10R is located on the lower side. A recess 10S recessed backward is formed between the release surface 10R and the locking surface 10Q.

[0022] The housing 10 is provided with a pair of upper and lower wall portions 10E covering each lance 10D. Each wall portion 10E is in the shape of a strip with its thickness direction facing the up-down direction, extends in the left-right direction, and is formed on the upper and lower sides intersecting with the front surface of the housing 10 (see FIG. 2). The upper wall portion 10E covers the upper lance 10D from above. The lower wall portion 10E covers the lower lance 10D from below. The rear end portion of the upper wall portion 10E is connected to the rear end portion of the upper lance 10D. The front portion of the upper wall portion 10E and the front portion of the upper lance 10D are spaced apart in the up-down direction to define and form a deflection allowable space R. The rear end portion of the lower lance 10D is connected to the rear end portion of the lower wall portion 10E. The front portion of the lower wall portion 10E and the front portion of the lower lance 10D are spaced apart in the up-down direction to define and form a deflection allowable space R. In other words, the wall portion 10E defines a deflection allowing space R between the wall portion 10E and the lance 10D. The deflection allowing space R is a space that allows the lance 10D to deflect.

[0023] A pair of upper and lower mounting holes 10F are formed in the rear of the wall portion 10E on the upper and lower sides of the housing 10. The upper mounting hole 10F communicates with each of the upper cavities 10B and opens upward (in a direction intersecting the front-to-rear direction) (see FIG. 2). The lower mounting hole 10F communicates with each of the lower cavities 10B and opens downward (in a direction intersecting the front-to-rear direction).

[0024] A pair of upper and lower punch holes 10G are formed in the upper and lower sides of the housing 10 in front of the wall portion 10E. The upper punch hole 10G communicates with each upper cavity 10B and opens upward (in a direction intersecting the front-rear direction) (see FIG. 2). The lower punch hole 10G communicates with each lower cavity 10B and opens downward (in a direction intersecting the front-rear direction). A retreat surface 10T is connected to the front end edge (a position forward of the release surface 10R) of each punch hole 10G, which is inclined forward as it approaches the opening 10W of the side surface 10U of the housing 10. A front end surface 10V extending in the up-down direction toward the side surface 10U of the housing 10 is connected to the front end edge of the retreat surface 10T. At the front end of the punch hole 10G, a recess 10P is formed by the retreat surface 10T and the front end surface 10V. The recess 10P is formed to be recessed downward and forward when viewed from the left-right direction. The locking surface 10Q and the releasing surface 10R of the lance 10D are disposed to face (face) the punch hole 10G.

[0025] As shown in FIG. 2, a pair of left and right first locking projections 10L, a pair of left and right second locking projections 10M, and a pair of left and right locking ribs 10N are provided on both left and right side surfaces of the housing 10, protruding outward in the left and right direction. In FIG. 2, a part of the first locking projection 10L and the second locking projection 10M on the right side and the locking rib 10N are not shown. The pair of left and right first locking projections 10L, the pair of left and right second locking projections 10M, and the pair of left and right locking ribs 10N are provided symmetrically on both left and right side surfaces of the housing 10. The first locking projections 10L have a function as a guide when the retainer 13 described later moves between a temporary locking position and a full locking position, and a function of holding the retainer 13 at the temporary locking position and the full locking position. The second locking projections 10M have a function of holding the retainer 13 at the temporary locking position and the full locking position. The locking rib 10N has the function of holding the retainer 13 at a provisional locking position and a full locking position.

[0026] The upper first locking projection 10L extends forward and downward at an incline, and the lower first locking projection 10L extends forward and upward at an incline.

[0027] The upper second locking projection 10M is disposed at the upper end of the housing 10, rearward and above the upper first locking projection 10L. The lower second locking projection 10M is disposed at the lower end of the housing 10, rearward and below the lower first locking projection 10L. The second locking projection 10M is disposed on the imaginary extension region E of the first locking projection 10L (see FIG. 7). The locking rib 10N is disposed at the rear end of the housing 10. The locking rib 10N extends in the front-rear direction. The locking rib 10N is disposed rearward of the first locking projection 10L (see FIG. 7).

[0028] [Conductive material configuration] The conductive member 11 is formed by pressing a metal plate. As shown in Fig. 4, the conductive member 11 has a connection portion 11A and a fastening portion 11B. The conductive member 11 has a configuration in which the fastening portion 11B, which is attached to a ground portion (not shown) of a vehicle, is provided adjacent to the rear edge side of the connection portion 11A.

[0029] The connection portion 11A includes a belt-like connecting portion 11C folded back into a U-shape, and a plurality of male terminals 11D extending backward in the form of tabs from the rear end edge of the connecting portion 11C, which are arranged at a predetermined interval. The interval between adjacent male terminals 11D in the left-right direction is the same as the interval between adjacent cavities 10B in the left-right direction. The interval between the upper connecting portion 11C, which is one side of the U-shape, and the lower connecting portion 11C, which is the other side of the U-shape, is the same as the interval between adjacent cavities 10B in the vertical direction. A plurality of locking projections 11E are formed on the lower surface of the upper connecting portion 11C and the upper surface of the lower connecting portion 11C in a direction approaching each other in the vertical direction.

[0030] The fastening portion 11B has a first cover portion 11F, a second cover portion 11J, and an attachment portion 11G. The first cover portion 11F is connected to the front end edge of the lower connecting portion 11C and extends downwardly. The second cover portion 11J is connected to the front end edge of the upper connecting portion 11C and extends downwardly. The second cover portion 11J is arranged to cover the first cover portion 11F from the rear. The attachment portion 11G is bent backward from the lower end edge of the first cover portion 11F. The lower end of the second cover portion 11J is connected to the upper surface of the attachment portion 11G. A through hole 11H is formed in the attachment portion 11G so as to penetrate in the plate thickness direction. A stud bolt provided on a vehicle (not shown) is inserted into the through hole 11H.

[0031] When inserting the connection portion 11A of the conductive member 11 into the terminal insertion groove 10A of the housing 10, each male terminal 11D is oriented so as to protrude backward, and the connection portion 11A is inserted into the terminal insertion groove 10A from the front. Then, the locking protrusion 11E passes backward through the locked portion 10K of the clamping portion 10J. As a result, the locking protrusion 11E is locked to the locked portion 10K from behind, and the connection portion 11A is prevented from coming off (see FIG. 5). In this way, the conductive member 11 is attached to the front portion of the housing 10.

[0032] Thereafter, each male terminal 11D is inserted into the corresponding cavity 10B from the front (see FIG. 5). The first cover portion 11F and the second cover portion 11J of the fastening portion 11B are arranged to cover the lower side of the front surface of the housing 10 from the front of the housing 10 (see FIG. 5).

[0033] [Female terminal configuration] The female terminal 12 forms a part of the conductive member 11. The female terminal 12 is formed by pressing a metal plate. As shown in FIG. 1, the female terminal 12 has a rectangular tube portion 12A extending in the front-rear direction and a barrel portion 12B connected to the rear of the rectangular tube portion 12A and to which the electric wire W is crimped. The female terminal 12 is inserted into the cavity 10B from the terminal insertion opening 10C and pushed in while elastically deforming the lance 10D. When the female terminal 12 abuts against the abutment portion 10H provided at the front end of the cavity 10B, the lance 10D elastically returns to its original state, and the locking surface 10Q is locked against the protrusion 12C provided on the upper surface of the rectangular tube portion 12A from the rear (see FIG. 5). Thus, the female terminal 12 is temporarily locked by the lance 10D in a non-removable state and is accommodated in the cavity 10B formed at the rear of the housing 10.

[0034] [Retainer configuration] The two retainers 13 are made of synthetic resin. The two retainers 13 are intended to prevent the female terminals 12 from being removed by secondarily engaging the rear ends of the rectangular tube portions 12A of the female terminals 12 inserted into the cavities 10B. Each retainer 13 is attached to the housing 10 so as to be displaceable between a temporary locking position and a temporary locking position diagonally rearward of the temporary locking position. The displacement direction of the retainer 13 is a direction that diagonally intersects with the insertion direction (front-rear direction) of the female terminals 12.

[0035] The two retainers 13 have the same configuration, and only differ in their mounting postures relative to the housing 10. For this reason, the configuration of the upper retainer 13 will be described, and a description of the configuration of the lower retainer 13 will be omitted. As shown in Fig. 6, the retainer 13 has a flat plate portion 13A, a pair of left and right side plate portions 13B hanging down from both left and right side edges of the plate portion 13A, a plurality of locking portions 13C protruding downward from the underside of the plate portion 13A, and a visor portion 13D.

[0036] The pair of side plate portions 13B are flat and have a plate thickness direction in the left-right direction. A guide hole 13E and a locking recess 13F are formed in each side plate portion 13B. The guide hole 13E is formed penetrating in the plate thickness direction. The guide hole 13E extends forward and downward. The locking recess 13F is formed in the rear end portion of each side plate portion 13B on the inner left-right direction and recessed outward. Each locking portion 13C is flat and has a plate thickness direction in the left-right direction, and is arranged side by side in the left-right direction with a predetermined interval between them. The eaves portion 13D is a portion that constitutes the front portion of the plate portion 13A. In other words, the eaves portion 13D is a portion that extends forward from the locking portion 13C.

[0037] [An example of connector assembly] First, the connecting portion 11A of the conductive member 11 is attached to the terminal insertion groove 10A of the housing 10 from the front.

[0038] Next, the retainer 13 is assembled to the housing 10. At this time, the side plate portions 13B are positioned along both side walls of the housing 10 in the left and right direction, and the plate portion 13A is positioned so as to cover the upper wall of the housing 10 from above (see FIG. 1). Then, the retainer 13 is brought close to the housing 10 from above, and the first locking projection 10L and the second locking projection 10M of the housing 10 are fitted into the guide holes 13E as shown in FIG. 7. At this time, the first locking projection 10L contacts the lower edge of the guide hole 13E of the retainer 13, and the second locking projection 10M contacts the upper edge. As a result, the retainer 13 is restricted from being displaced relative to the housing 10. At this time, the position of the retainer 13 is the provisional locking position. The lower end of the locking portion 13C is positioned inside the mounting hole 10F (see FIG. 5).

[0039] Next, the female terminal 12 is attached from the rear to the cavity 10B of the housing 10. At this time, the male terminal 11D of the connecting portion 11A of the conductive member 11 is inserted from the front into the square tube portion 12A of the female terminal 12, and the female terminal 12 is connected to the conductive member 11 (see FIG. 5).

[0040] When the retainer 13 is placed in the provisionally retained position, the eaves 13D is placed so as to cover the rear of the removal hole 10G of the housing 10 from above. This causes the front of the removal hole 10G to be open upward. When removing the female terminal 12, a jig G is inserted into the removal hole 10G of the housing 10 from a direction intersecting the front-rear direction, and the release surface 10R of the lance 10D is pressed upward to release the lock of the lance 10D with respect to the female terminal 12. Specifically, the jig G is brought into contact with the release surface 10R formed on the front end of the lance 10D in a state where the lance 10D is locked with the protrusion 12C of the square tube portion 12A, and the release surface 10R is pressed, so that the lance 10D is elastically deformed so as to enter the deflection allowance space R. This releases the lock of the lance 10D with respect to the female terminal 12, and the female terminal 12 can be removed from the cavity 10B. In addition, since the tip of the jig G enters the recessed portion 10S, the contact area (engagement) of the jig G with the release surface 10R can be secured, making it difficult for the jig G to come off the release surface 10R. In addition, the retreat surface 10T is inclined forward away from the release surface 10R as it approaches the opening 10W of the side surface 10U, so that it is difficult for it to interfere with the application of the jig G to the release surface 10R.

[0041] Next, after inserting the female terminal 12, the retainer 13 is pushed from the provisional locking position to the full locking position. At this time, an operating force exceeding the locking force between the upper end of the guide hole 13E and the second locking projection 10M is applied to the retainer 13, and each side plate portion 13B is elastically deformed outward in the left-right direction. During the process of displacement of the retainer 13, the second locking projection 10M is released from the guide hole 13E, and the first locking projection 10L is kept engaged with the guide hole 13E (see Figs. 7 and 8). As a result, the retainer 13 moves parallel to the moving path along the guide hole 13E.

[0042] When the retainer 13 reaches the full locking position, as shown in Fig. 8, the upper edge of the guide hole 13E comes into contact with the first locking projection 10L and the locking rib 10N enters the locking recess 13F, thereby holding the retainer 13 in the full locking position. Each locking portion 13C is disposed inside the mounting hole 10F and secondarily locks from the rear with the rectangular tube portion 12A of the corresponding female terminal 12, so that all the female terminals 12 are prevented from falling out by the retainer 13. In other words, the primary locking action by the lance 10D and the secondary locking action by the retainer 13 reliably hold the female terminals 12 in a prevented state.

[0043] When the retainer 13 is held in the full locking position, the front end of the eaves portion 13D of the retainer 13 enters the recess 10P and blocks the punch hole 10G. At this time, the front end of the eaves portion 13D faces the retreat surface 10T and the front end surface 10V from behind. When the retainer 13 is in the full locking position, the punch hole 10G of the housing 10 is covered from above by the eaves portion 13D. At this time, the insertion of the jig G into the punch hole 10G to release the lock of the lance 10D is restricted. The lower retainer 13 is attached to the housing 10 from below in a position that is upside down relative to the upper retainer 13, so a description thereof will be omitted.

[0044] Each retainer 13 can also be displaced from the full locking position toward the partial locking position. That is, the retainer 13 can move between the partial locking position and the partial locking position relative to the housing 10. In this case, the retainer 13 moves rearward from the full locking position to the partial locking position, so that the visor portion 13D also moves rearward, and the front portion of the punch hole 10G is opened upward (downward) (see FIG. 7).

[0045] Next, the operation of the first embodiment will be described. The connector 1 includes a housing 10, a conductive member 11, a female terminal 12, and a retainer 13. The conductive member 11 is attached to the front of the housing 10. The female terminal 12 is accommodated in the rear of the housing 10 and connected to a connecting portion 11A of the conductive member 11. The retainer 13 is arranged to be movable between a provisional locking position and a full locking position with respect to the housing 10. The conductive member 11 has a first cover portion 11F and a second cover portion 11J that cover the front surface of the housing 10. The housing 10 has a lance 10D, a deflection allowance space R, a wall portion 10E, an attachment hole 10F, and a removal hole 10G. The lance 10D is elastically deformable and primarily locks the female terminal 12. The deflection allowance space R is a space that allows the lance 10D to deflect. The wall portion 10E is formed on the upper and lower sides intersecting with the front surface to define a deflection-allowing space R between the lance 10D and the mounting hole 10F. The mounting hole 10F opens on the upper and lower sides rearward of the wall portion 10E. The extraction hole 10G opens on the upper and lower sides forward of the wall portion 10E. The retainer 13 is disposed inside the mounting hole 10F and has an engagement portion 13C that secondarily engages the female terminal 12 in the main engagement position. The lance 10D has a release surface 10R disposed toward the extraction hole 10G.

[0046] According to this configuration, punch hole 10G can be formed so as to open on the upper and lower side surfaces that intersect with the front surface, so that even if conductive member 11 covers the front surface of housing 10 and a jig cannot be inserted from the front surface, lance 10D can be operated through punch hole 10G. Also, because punch hole 10G and mounting hole 10F open on the upper and lower side surfaces that intersect with the front surface, punch hole 10G and mounting hole 10F can be formed using a single slide die in the die, so that the die structure does not need to be complicated.

[0047] The retainer 13 has a visor portion 13D extending forward from the locking portion 13C, and the visor portion 13D closes the extraction hole 10G in the full locking position and opens the extraction hole 10G in the temporary locking position. With this configuration, it is possible to limit or allow the release of the locking of the lance 10D.

[0048] Retainer 13 moves obliquely backward from the full locking position to the temporary locking position. With this configuration, when retainer 13 is disposed at the temporary locking position, overhanging portion 13D can open the front portion of punch hole 10G, making it easier to insert jig G into punch hole 10G in a direction intersecting the front-rear direction.

[0049] The punching hole 10G has a retreat surface 10T inclined forward as it approaches the opening 10W of the side surface 10U, forward of the release surface 10R. With this configuration, the retreat surface 10T allows freedom in how the jig G is inserted into the punching hole 10G. Also, the jig G can be made to act on the release surface 10R without interfering with the retreat surface 10T.

[0050] <Other embodiments> The embodiments disclosed herein should be considered to be illustrative and not restrictive in all respects. The scope of the present invention is not limited to the embodiments disclosed herein, but is indicated by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0051] Unlike the first embodiment, a single retainer may be attached to the housing.
