[0009] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described by way of examples. (1) A connector comprising: case; A conductive member mounted on the front of the housing; a terminal housed in the rear portion of the housing and connected to a connecting portion of the conductive member; and The retaining body is arranged on the housing so as to be movable between a temporary locking position and a formal locking position. The conductive member has a covering portion that covers at least a portion of a front surface of the housing, The housing comprises: a lance-shaped portion capable of elastic deformation, which initially locks the terminal; a flexure-allowing space, which allows the flexure of the lance-shaped portion; a wall portion, which is formed on a side surface intersecting the front surface, and defines the flexure-allowing space between the lance-shaped portion; a mounting hole, which opens on the side surface more rearward than the wall portion; and a pull-out hole, which opens on the side surface more forward than the wall portion. The retaining body has a locking portion, which is arranged inside the mounting hole and locks the terminal at the second level at the formal locking position. The lance has a release surface disposed so as to face the extraction hole.

[0010] In the connector of (1), since the extraction hole can be formed to open on the side, even if the conductive member is in a state of covering the front surface of the housing and the jig cannot be inserted from the front surface, the lance can be operated through the extraction hole using the jig. In addition, since the extraction hole and the mounting hole are opened on the side intersecting the front surface, the extraction hole and the mounting hole can be formed by using one sliding mold in the mold, and the mold structure can be made simple.

[0011] (2) In the connector described in (1), the retaining body has a flange portion extending forward from the locking portion, The flange portion closes the extraction hole at the permanent locking position, and opens the extraction hole at the temporary locking position.

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

[0013] (3) In the connector described in (2), the holding body moves rearward from the permanent locking position to the temporary locking position.

[0014] In the connector of (3), when the retaining body is arranged at the temporary locking position, the flange portion can open the front portion of the extraction hole, so the jig can be easily inserted into the extraction hole from a direction intersecting the front-rear direction.

[0015] (4) In the connector described in any one of (1) to (3), the extraction hole has a relief surface in front of the release surface, and the relief surface is inclined forward as it approaches the opening of the side surface.

[0016] The connector of (4) can provide a degree of freedom in the method of inserting the jig into the extraction hole by the escape surface. In addition, the jig can act on the release surface without interfering with the escape surface.

[0017] [Details of Embodiments of the Invention] <Implementation Method 1> Reference Figures 1 to 8 Embodiment 1 that embodies the connector 1 of the present invention is described. In the figure, "front side", "rear side", "upper side", "lower side", "right side" and "left side" are represented by "F", "B", "U", "D", "R" and "L", respectively. In addition, the reference of the direction is specified for convenience and may not be consistent with the direction of the connector 1 when it is mounted on a vehicle or the like. For example, the up and down direction is not limited to the direction of gravity.

[0018] [Connector Configuration] like Figure 1As shown, the connector 1 includes a housing 10 , a conductive member 11 , female terminals 12 as terminals, and two holding bodies 13 .

[0019] [Case Structure] The housing 10 is made of synthetic resin. The housing 10 is block-shaped. Figure 2 As shown, a terminal insertion groove 10A is formed at the front of the housing 10, and a connecting portion 11A of the conductive member 11 described later is installed in the terminal insertion groove 10A. The terminal insertion groove 10A is formed with two layers of grooves that are open to 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. Figure 3 As shown in FIG. 1 , a locked portion 10K is provided at the front end portion of the clamping portion 10J so as to protrude upward and downward.

[0020] At the rear of the housing 10, cavities 10B are formed in two layers, one above the other, and arranged in the vertical direction and the other side. The female terminal 12 described later is installed in the cavity 10B. The rear end of each cavity 10B is opened at the rear end surface of the housing 10 as a terminal insertion port 10C. A lance 10D is provided in each cavity 10B. The lance 10D extends forward in a cantilever shape and is formed to be elastically deformable. The lance 10D is arranged 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 is locked to the female terminal 12 and a release surface 10R that is pressed by a jig G described later to release the locking of the lance 10D relative to the female terminal 12. In the upper lance 10D, the locking surface 10Q is arranged on the lower side of the front end of the lance 10D. In the upper lance 10D, the release surface 10R is arranged on the upper side. In the lower lance 10D, the locking surface 10Q is arranged on the upper side of the front end of the lance 10D. In the lower lance 10D, the release surface 10R is arranged on the lower side. A recessed portion 10S that is recessed toward the rear 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 walls 10E covering each lance 10D. Each wall 10E is in a strip shape with the plate thickness direction oriented in the vertical direction, extending in the left-right direction, and formed on the upper side and the lower side intersecting the front surface of the housing 10 (see Figure 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 separated in the vertical direction, defining a bending allowance space R. The rear end portion of the lower wall portion 10E is connected to the rear end portion of the lower lance 10D. The front portion of the lower wall portion 10E and the front portion of the lower lance 10D are separated in the vertical direction, defining a bending allowance space R. In other words, the bending allowance space R is defined between the wall portion 10E and the lance 10D. The bending allowance space R is a space that allows the bending action of the lance 10D.

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

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

[0025] like Figure 2 As shown, on both side surfaces of the housing 10 in the left and right directions, a pair of left and right first locking protrusions 10L, a pair of left and right second locking protrusions 10M, and a pair of left and right locking ribs 10N are provided to protrude outward in the left and right directions. Figure 2In the figure, the first locking protrusion 10L and a part of the second locking protrusion 10M and the locking rib 10N on the right side are not shown. The left and right pair of first locking protrusions 10L, the left and right pair of second locking protrusions 10M, and the left and right pair of locking ribs 10N are symmetrically arranged on both side surfaces of the housing 10 in the left-right direction. The first locking protrusion 10L has a function as a guide portion when the retaining body 13 described later moves between the temporary locking position and the formal locking position, and a function of retaining the retaining body 13 at the temporary locking position and the formal locking position. The second locking protrusion 10M has a function of retaining the retaining body 13 at the temporary locking position and the formal locking position. The locking rib 10N has a function of retaining the retaining body 13 at the temporary locking position and the formal locking position.

[0026] The first locking projection 10L on the upper side extends obliquely forward and downward. The first locking projection 10L on the lower side extends obliquely forward and upward.

[0027] The second locking protrusion 10M on the upper side is arranged at the upper end of the housing 10 and at the rear upper side of the first locking protrusion 10L on the upper side. The second locking protrusion 10M on the lower side is arranged at the lower end of the housing 10 and at the rear lower side of the first locking protrusion 10L on the lower side. The second locking protrusion 10M is arranged on the overhead extension area E of the first locking protrusion 10L (refer to Figure 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 behind the first locking protrusion 10L (see Figure 7 ).

[0028] [Constitution of the Conductive Member] The conductive member 11 is formed by stamping a metal plate. Figure 4 As shown, the conductive member 11 has a connecting portion 11A and a fastening portion 11B. The conductive member 11 is in a form in which the fastening portion 11B to be mounted on a grounding portion (not shown) of a vehicle is continuously provided on the rear edge side of the connecting portion 11A.

[0029] The connecting portion 11A is provided with a strip-shaped connecting portion 11C folded back into a U-shape and a plurality of male terminals 11D extending backward in a tab-like manner from the rear end edge of the connecting portion 11C at predetermined intervals. The interval between the male terminals 11D adjacent to each other in the left-right direction is the same as the interval between the cavities 10B adjacent to each other in the left-right direction. The interval between the upper connecting portion 11C as one side of the U-shape and the lower connecting portion 11C as the other side of the U-shape is the same as the interval between the cavities 10B adjacent to each other in the upper and lower directions. A plurality of locking protrusions 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 upper and lower directions.

[0030] The fastening portion 11B includes a first covering portion 11F as a covering portion, a second covering portion 11J as a covering portion, and an assembly portion 11G. The first covering portion 11F is connected to the front end edge of the lower connecting portion 11C and extends in a downward bending manner. The second covering portion 11J is connected to the front end edge of the upper connecting portion 11C and extends in a downward bending manner. The second covering portion 11J is configured to cover the first covering portion 11F from the front. The assembly portion 11G extends in a backward bending manner from the lower end edge of the first covering portion 11F. The lower end portion of the second covering portion 11J is connected to the upper surface of the assembly portion 11G. In the assembly portion 11G, a through hole 11H is formed to penetrate in the plate thickness direction. A stud bolt provided in a vehicle not shown in the figure is inserted through the through hole 11H.

[0031] When the connecting portion 11A of the conductive member 11 is inserted into the terminal insertion slot 10A of the housing 10, the male terminals 11D are positioned to protrude rearward, and the connecting portion 11A is inserted into the terminal insertion slot 10A from the front. Then, the locking protrusion 11E passes through the locked portion 10K of the clamping portion 10J backward. As a result, the locking protrusion 11E is locked to the locked portion 10K from the rear, and the connecting portion 11A is in a state of being prevented from falling off (see Figure 5 ). In this way, the conductive member 11 is installed at the front of the housing 10.

[0032] Then, each male terminal 11D enters the corresponding cavity 10B from the front (see Figure 5 ). The first covering portion 11F and the second covering portion 11J of the fastening portion 11B are in a state of covering the lower side of the front surface of the housing 10 from the front of the housing 10 (see Figure 5 ).

[0033] [Constitution of female terminal] The female terminal 12 constitutes a part of the conductive member 11. The female terminal 12 is formed by stamping a metal plate. Figure 1 As shown, the female terminal 12 has: a square tube portion 12A, which is in the shape of a square tube and extends in the front-to-back direction; and a cylindrical portion 12B, which is connected to the rear of the square tube portion 12A, and the wire W is crimped to the cylindrical portion 12B. The female terminal 12 is inserted into the cavity 10B from the terminal insertion port 10C, and the lance 10D is pressed in while elastically deforming. When the female terminal 12 abuts against the abutment portion 10H provided at the front end of the cavity 10B, the lance 10D is elastically reset, and the locking surface 10Q is locked from the rear to the protrusion 12C provided on the upper surface of the square tube portion 12A (refer to Figure 5 In this way, the female terminal 12 is primarily locked by the lance 10D in a state of preventing it from coming out, and is accommodated in the cavity 10B formed in the rear portion of the housing 10 .

[0034] [Constitution of the holding body] The two retaining bodies 13 are made of synthetic resin. The two retaining bodies 13 are used to prevent the female terminals 12 from falling out by engaging with the rear ends of the square tubes 12A of the plurality of female terminals 12 inserted into the cavity 10B in a two-stage manner. Each retaining body 13 can be assembled to the housing 10 so as to be displaceable between a formal engaging position and a temporary engaging position which is located obliquely rearward relative to the formal engaging position. The displacement direction of the retaining body 13 is a direction obliquely intersecting with the insertion direction (front-rear direction) of the female terminal 12.

[0035] The two retaining bodies 13 are of the same form, but are assembled in different postures relative to the housing 10. Therefore, the structure of the upper retaining body 13 will be described, and the structure of the lower retaining body 13 will be omitted. Figure 6 As shown, the retaining body 13 includes a flat plate portion 13A, a pair of left and right side plate portions 13B hanging from both side edges of the plate portion 13A in the left and right directions, a plurality of stopper portions 13C protruding downward from the lower surface of the plate portion 13A, and an eave portion 13D.

[0036] A pair of side plate portions 13B are in the shape of a flat plate with the plate thickness direction facing 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 to penetrate in the plate thickness direction. The guide hole 13E extends obliquely forward and downward. The locking recess 13F is formed to be recessed outward at the rear end portion of the inner side in the left-right direction of each side plate portion 13B. Each locking portion 13C is in the shape of a flat plate with the plate thickness direction facing the left-right direction, and is arranged in the left-right direction at predetermined intervals. The eaves portion 13D is a portion constituting the front portion of the plate portion 13A. In other words, the eaves portion 13D is a portion extending forward from the locking portion 13C.

[0037] [Example of Connector Assembly] First, the connection portion 11A of the conductive member 11 is fitted into 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 plates 13B are arranged so as to be along the respective side walls in the left-right direction of the housing 10, and the plate 13A is arranged so as to cover the upper wall of the housing 10 from above (see Figure 1 ). And, the holding body 13 is brought close to the housing 10 from above, as shown in FIG. Figure 7 As shown, the first locking protrusion 10L and the second locking protrusion 10M of the housing 10 are engaged with the guide holes 13E. At this time, the first locking protrusion 10L is in contact with the lower edge of the guide hole 13E of the retaining body 13, and the second locking protrusion 10M is in contact with the upper edge of the guide hole 13E of the retaining body 13. As a result, the retaining body 13 is restricted from displacement relative to the housing 10. The position of the retaining body 13 at this time is a temporary locking position. The lower end of the locking portion 13C is arranged inside the mounting hole 10F (refer to Figure 5 ).

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

[0040] When the retaining body 13 is arranged in the temporary locking position, the flange portion 13D is arranged so as to cover the rear portion of the extraction hole 10G of the housing 10 from above. As a result, the front portion of the extraction hole 10G is opened upward. When the female terminal 12 is to be pulled out, the jig G is inserted into the extraction 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, thereby releasing the locking of the lance 10D with respect to the female terminal 12. Specifically, by bringing the jig G into contact with the release surface 10R formed at the front end of the lance 10D in the state of being locked to the protrusion 12C of the square tube 12A and pressing the release surface 10R, the lance 10D is elastically deformed to enter the deflection-allowing space R. As a result, the locking of the lance 10D with respect to the female terminal 12 can be released, and the female terminal 12 can be pulled out from the cavity 10B. In addition, since the tip of the jig G enters the recessed portion 10S, the contact area (locking amount) of the jig G with respect to the release surface 10R can be ensured, the jig G is not easily separated from the release surface 10R. In addition, since the retreat surface 10T is inclined toward the front away from the release surface 10R as it approaches the opening 10W of the side surface 10U, it is not easy to become an obstacle when the jig G acts on the release surface 10R.

[0041] Next, after the female terminal 12 is inserted, the retaining body 13 is pushed from the temporary locking position to the formal locking position. At this time, an operating force exceeding the locking force of the upper end of the guide hole 13E and the second locking protrusion 10M is applied to the retaining body 13, so that each side plate portion 13B is elastically deformed outward in the left and right directions. During the displacement of the retaining body 13, the second locking protrusion 10M is kept disengaged from the guide hole 13E and the first locking protrusion 10L is kept in the state of being engaged with the guide hole 13E (refer to Figure 7 , 8 ). As a result, the holding body 13 moves in parallel along the moving path along the guide hole 13E.

[0042] When the retaining body 13 reaches the formal locking position, Figure 8As shown in the figure, the upper edge of the guide hole 13E contacts the first locking protrusion 10L, and the locking rib 10N enters the locking recess 13F, thereby the retaining body 13 is retained in the formal locking position. Each locking portion 13C is arranged inside the mounting hole 10F and is locked to the corresponding square tube portion 12A of the female terminal 12 from the rear in a secondary manner, so that all the female terminals 12 are prevented from falling off by the retaining body 13. That is, the female terminal 12 is reliably retained in a state of preventing falling off by the primary locking action of the lance 10D and the secondary locking action of the retaining body 13.

[0043] When the retaining body 13 is held in the formally locked position, the front end of the flange 13D of the retaining body 13 enters the recess 10P to close the extraction hole 10G. At this time, the front end of the flange 13D is opposite to the retreat surface 10T and the front end surface 10V from the rear. When the retaining body 13 is in the formally locked position, the extraction hole 10G of the housing 10 is covered by the flange 13D from above. At this time, the insertion of the jig G into the extraction hole 10G is restricted to release the locking of the lance 10D. The lower retaining body 13 is assembled to the housing 10 from below in a posture reversed in the up-down direction relative to the upper retaining body 13, so the description is omitted.

[0044] Each retaining body 13 can also be displaced from the formal locking position to the temporary locking position. That is, the retaining body 13 can move between the temporary locking position and the formal locking position relative to the housing 10. In this case, since the retaining body 13 moves backward from the formal locking position to the temporary locking position, the flange portion 13D also moves backward, and the front portion of the extraction hole 10G opens upward (downward) (refer to Figure 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 retaining body 13. The conductive member 11 is mounted on the front of the housing 10. The female terminal 12 is housed in the rear of the housing 10 and is connected to a connecting portion 11A of the conductive member 11. The retaining body 13 is arranged on the housing 10 so as to be movable between a temporary locking position and a formal locking position. The conductive member 11 includes a first covering portion 11F and a second covering portion 11J covering the front surface of the housing 10. The housing 10 includes a lance 10D, a bending allowable space R, a wall 10E, a mounting hole 10F, and a removal hole 10G. The lance 10D is elastically deformable and primarily engages the female terminal 12. The bending allowable space R is a space that allows the bending motion of the lance 10D. The wall 10E is formed on the upper side surface and the lower side surface intersecting the front surface, and defines the bending allowable space R between the lance 10D and the lance 10D. The mounting hole 10F is opened on the upper side and the lower side of the wall portion 10E. The extraction hole 10G is opened on the upper side and the lower side of the wall portion 10E. The retaining body 13 has a locking portion 13C, which is arranged inside the mounting hole 10F and locks the female terminal 12 in the second stage at the formal locking position. The lance 10D has a release surface 10R arranged so as to face the extraction hole 10G.

[0046] According to this configuration, since the extraction hole 10G can be formed to open on the upper side and the lower side that intersect the front surface, even if the conductive member 11 is in a state of covering the front surface of the housing 10 and the jig cannot be inserted from the front surface, the lance 10D can be operated through the extraction hole 10G. In addition, since the extraction hole 10G and the mounting hole 10F are opened on the upper side and the lower side that intersect the front surface, the extraction hole 10G and the mounting hole 10F can be formed by using one sliding mold in the mold, and the mold structure can be made simple.

[0047] The retaining body 13 has a flange 13D extending forward from the locking portion 13C. The flange 13D closes the extraction hole 10G in the permanent locking position and opens the extraction hole 10G in the temporary locking position. This configuration can restrict or allow the locking release of the lance 10D.

[0048] The retaining body 13 moves obliquely rearward from the formal locking position to the temporary locking position. According to this configuration, when the retaining body 13 is arranged at the temporary locking position, the flange portion 13D can open the front portion of the extraction hole 10G, so the jig G can be easily inserted into the extraction hole 10G from a direction intersecting the front-rear direction.

[0049] The extraction hole 10G has a retreat surface 10T in front of the release surface 10R, and the retreat surface 10T is inclined forward as it approaches the opening 10W of the side surface 10U. According to this structure, the retreat surface 10T can provide a degree of freedom in the insertion method of the jig G into the extraction hole 10G. In addition, the jig G can act on the release surface 10R without interfering with the retreat surface 10T.

[0050] <Other Implementation Methods> The embodiments disclosed herein are to be considered in all respects as illustrative and non-restrictive. 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 equivalent to the claims.

[0051] Unlike the first embodiment, a configuration in which one holding body is mounted on the housing may be adopted.

[0052] Unlike the first embodiment, the wall portion may be formed on the left side surface and the right side surface intersecting the front surface of the housing.

[0053] Unlike the first embodiment, a configuration may be adopted in which a male terminal having a protruding piece is used as a terminal, and a female terminal is used as a connecting portion.

[0054] Unlike the first embodiment, a configuration may be adopted in which the holding body does not move while being inclined with respect to the front-rear direction but moves along the front-rear direction. Description of Reference Numerals
