  The second terminal housing 7 is preferably formed of a metal such as aluminum having high electrical conductivity and thermal conductivity to reduce the shielding performance, heat dissipation, and weight of the connector 1, but is formed of resin or the like. You may make it do. In the present embodiment, the cylindrical body 36 is made of aluminum.

  Further, in the second connector portion 3, the cables 61a to 61c are connected to the second cables 61a to 61c so that the vibrations of the cables 61a to 61c are transmitted to the contacts and the first joint terminals 4a to 4c and the second joint terminals 6a to 6c are not worn. It is fixed to the terminal housing 7.

  Specifically, as shown in FIG. 7, the cables 61 a to 61 c are sandwiched and sandwiched by a tail plate 50 having a two-divided structure provided with holes 50 a through which the cables 61 a to 61 c are inserted. The cables 61a to 61c are fixed to the cable insertion portion 36a via the tail plate 50 by locking 50b in a groove 36d (see FIG. 10) provided in the cable insertion portion 36a. In the present embodiment, two tail plates 50 are used to more firmly fix the cables 61a to 61c. The movement of the tail plate 50 to the inside of the cylindrical body 36 is restricted by the wall around the insertion hole 36f (see FIG. 10A), and the cables 61a to 61b are forced to the inside of the cylindrical body 36. It also plays a role in reducing intrusion. Further, the tail plate 50 plays a role of retaining a waterproof packing (not shown) that reduces water intrusion into the second terminal housing 7 through the cables 61 a to 61 c in the second terminal housing 7. The waterproof packing is provided between the two tail plates 50.

  As shown in FIGS. 1, 6, and 7, the plurality of insulating members 8 a to 8 d are housed aligned in the second terminal housing 7 and the other surfaces of the plurality of second joining terminals 6 a to 6 c (first joining). A plurality of first insulating members 8b to 8d integrally provided on each of the surfaces opposite to the surfaces bonded to the terminals 4a to 4c), the plurality of first bonding terminals 4a to 4c and the plurality of second bonding terminals. The other surface of the first joint terminal 4a located on the outermost side (the uppermost side in FIGS. 1, 6 and 7) when 6a to 6c are in a laminated state (the side opposite to the surface joined to the second joint terminal 6a) And a second insulating member 8a provided so as to face the surface.

  In the connector 1 according to the present embodiment, the insulating members 8a to 8d are connected to each other, and the insulating member restricting means 101 that restricts the movement in the direction perpendicular to the stacking direction of the stacked structure of the insulating members 8a to 8d. The insulating member assembly 100 having the structure is configured. The insulating member restricting means 101 is configured to restrict the movement of the insulating members 8a to 8d in the XY plane when considering an orthogonal coordinate system in which the stacking direction of the stacked structure is the Z axis.

  Insulating member assembly 100 has holes for inserting both joining terminals 4a to 4c and 6a to 6c inserted in the orthogonal direction, that is, a first terminal insertion for inserting first joining terminals 4a to 4c. A hole 102 and a second terminal insertion hole 103 for inserting the second joining terminals 6a to 6c are formed. The first terminal insertion hole 102 is formed between adjacent insulating members 8a to 8d, and the second terminal insertion hole 103 is formed in each first insulating member 8b to 8d. Details of the insulating member assembly 100 will be described later.

  As shown in FIG. 12, the connection member 9 includes a cam 9a and a bolt 9b. The cam 9a is formed in a cylindrical shape that opens only downward, and has a deformed hole (here, a hexalobular hole) 9c formed on its upper surface so that it can be rotated by fitting a tool such as a wrench. It has become. On the side surface of the cam 9a, a groove 9g for receiving a packing 14 (see FIG. 1A) such as an O-ring that reduces the ingress of water into the second terminal housing 7 is formed. The lower portion of the cam 9a (including the position where the groove 9g is formed) is enlarged in a flange shape, and the cam 9a is inserted into the connection member insertion hole 26 of the second terminal housing 7 as shown in FIG. By inserting and fixing the ring-shaped fixing member 26b into the groove 26a formed on the inner peripheral surface of the connecting member insertion hole 26, the flange portion interferes with the fixing member 26b and the cam 9a moves outward. The cam 9a is rotatably held between the second terminal housing 7 and the fixing member 26b.

  The upper part of the bolt 9b is inserted into the hollow part of the cam 9a. The bolt 9b is formed in a cylindrical shape that opens only downward, and a convex portion 9d is formed so as to protrude outward from a circumferentially opposed position (see FIG. 12D). The lower portion of the bolt 9b is enlarged in a flange shape, and a notch 9e formed in the flange portion is formed into a vertically extending projection 36e (see FIG. 10A) formed in the second terminal housing 7. By slidably engaging, it is possible to slide in the vertical direction without rotating with the rotation of the cam 9a.

  A slope 9f that gradually protrudes downward along the circumferential direction is formed at the peripheral edge of the upper surface in the hollow portion of the cam 9a. Two slopes 9f are formed at positions 180 degrees rotationally symmetric with respect to the rotation axis of the cam 9a so as to correspond to the two convex portions 9d of the bolt 9b. A stopper 9h that interferes with the convex portion 9d of the bolt 9b and reduces over-rotation of the cam 9a is provided at the end portion of the slope 9f that protrudes downward.

  In this connection member 9, when the cam 9a is rotated, the slope 9f interferes with the convex portion 9d of the bolt 9b and moves the bolt 9b toward the second insulating member 8a to press the second insulating member 8a. ing. With this configuration, the cam 9a rotated by the worker is always at a fixed position and cannot move up and down, so that workability is improved.

  As the cam 9a and the bolt 9b, for example, one made of a metal such as SUS, iron, or copper alloy may be used. In addition, although the thing made from resin may be used as the cam 9a and the volt | bolt 9b, it is preferable to use a metal thing from a viewpoint of intensity | strength.

  Further, an elastic member 15 that applies a predetermined pressing force to the second insulating member 8a is provided between the bolt 9b of the connecting member 9 and the upper surface of the second insulating member 8a immediately below the bolt 9b. In the present embodiment, the upper portion of the elastic member 15 is accommodated in the hollow portion of the bolt 9b. This is a device for reducing the size of the connector 1 by shortening the distance between the bolt 9b and the second insulating member 8a even when the length of the elastic member 15 is long to some extent. The elastic member 15 is composed of a metal (for example, SUS) spring. In the present embodiment, the elastic member 15 is positioned as a part of the connection member 9.

  A concave portion 16 (see FIG. 7) that covers (stores) the lower portion of the elastic member 15 is formed on the upper surface of the second insulating member 8a with which the lower portion of the elastic member 15 abuts, and the bottom of the concave portion 16 (that is, the elastic member 15). (The seat portion where the lower part of the base plate abuts) is provided with a receiving member 17 made of metal (for example, SUS) that receives the elastic member 15 and reduces damage to the second insulating member 8a made of insulating resin.

  The receiving member 17 is for reducing damage to the second insulating member 8a by dispersing the stress applied from the elastic member 15 to the upper surface of the second insulating member 8a. Therefore, it is preferable to make the contact area between the receiving member 17 and the second insulating member 8a as large as possible. In the present embodiment, in order to increase the contact area between the receiving member 17 and the second insulating member 8a, the receiving member 17 having a shape that contacts the entire bottom surface of the recess 16 is provided.

[Connection between the first connector portion and the second connector portion]
When the terminal housings 5 and 7 are fitted, the first joint terminals 4a to 4c are inserted into the first terminal insertion holes 102, respectively, and the pair of second joint terminals 6a to 6c and the insulating members 8a to 8d. Inserted between. And by this insertion, while facing each of one surface of several 1st junction terminals 4a-4c and each of one surface of several 2nd junction terminals 6a-6c, it is 1st junction terminal 4a-. 4c, second joining terminals 6a to 6c, and insulating members 8a to 8d are alternately arranged, that is, the first joining terminals 4a to 4c and the second joining terminals 6a to 6c are paired with the insulating members 8a to 8d. It will be in the lamination state arrange | positioned so that may be pinched | interposed.

  At this time, each of the first insulating members 8b to 8d is provided inside the second connector portion 3 at the tip end side of the second joint terminals 6a to 6c that are held in alignment with being separated at a predetermined interval. Therefore, the interval between the insulating members 8b to 8d can be maintained without separately providing a holding jig or the like for holding the interval between the insulating members 8b to 8d. Thereby, each of the 1st junction terminals 4a-4c can be easily inserted between each of the 2nd junction terminals 6a-6c used as a pair, and insulating member 8a-8d. That is, the insertability of the first joint terminals 4a to 4c is not lowered. In addition, since it is not necessary to provide a holding jig for holding the interval between the insulating members 8b to 8d, it is very effective in that further downsizing can be realized as compared with the conventional case.

  Further, the contact point related to the first joint terminal 4a and the second joint terminal 6a is sandwiched between the second insulation member 8a and the first insulation member 8b provided on the second joint terminal 6a constituting the contact point. Similarly, the first insulating member 8c (or 6c) provided on the second joint terminal 6b (or 6c) that constitutes the contact is a contact point related to the first joint terminal 4b (or 4c) and the second joint terminal 6b (or 6c). Or 8d) and the first insulating member 8b (or 8c) provided on the second junction terminal 6a (or 6b) constituting another contact.

  In this state, when the cam 9a of the connecting member 9 is rotated with a tool such as a wrench and the cam 9a is pushed downward, the elastic member 15 causes the second insulating member 8a, the first insulating member 8b, the first insulating member 8c, The insulating members 8d are pressed in this order, and each of the contacts is pressed so as to be sandwiched between any two of the insulating members 8a to 8d to apply a pressing force to each contact, and the contacts are insulated from each other. It is touched in the state that was done. At this time, each of the first joint terminals 4a to 4c and each of the second joint terminals 6a to 6c are slightly bent by the pressing from the insulating members 8a to 8d and are brought into contact in a wide range. As a result, each contact point is firmly contacted and fixed even in an environment such as a vehicle that generates vibrations.

[Insulation member assembly]
Next, the insulating member assembly 100 will be described in detail.

  As shown in FIGS. 1, 7, and 13, the insulating member assembly 100 is configured by sequentially connecting the insulating members 8a to 8d in the stacking direction. That is, the insulating member assembly 100 is configured by connecting the second insulating member 8a and the first insulating member 8b, the first insulating member 8b and the first insulating member 8c, and the first insulating member 8c and the first insulating member 8d, respectively. Is done.

  In the insulating member assembly 100, the insulating member restricting means 101 restricts the movement of the insulating members 8a to 8d in the direction perpendicular to the stacking direction when the insulating members 8a to 8d are connected. In the insulating member assembly 100, the insulating members 8a to 8d are coupled so as to be relatively movable in the stacking direction in order to transmit the pressing force by the connecting member 9 to the respective contacts.

  The insulating member restricting means 101 includes a plurality of connecting pieces 81 provided on one of the insulating members 8a to 8d adjacent in the stacking direction and protruding toward the other of the adjacent insulating members 8a to 8d, and the adjacent insulating members 8a to 8d. And a plurality of connection grooves 82 which are provided so as to correspond to the plurality of connection pieces 81 and slidably accommodate the plurality of connection pieces 81 in the stacking direction.

  In the present embodiment, the insulating members 8a to 8d are formed so that the shape viewed from the stacking direction is substantially rectangular, and at least two of the four corners of the insulating members 8a to 8d are connected to the connecting pieces. One or both of 81 and the connecting groove 82 are formed. Here, a case will be described in which one or both of the connecting piece 81 and the connecting groove 82 are formed in each of the four corners of the insulating members 8a to 8d.

  In the insulating member assembly 100, the first insulating members 8b to 8d are provided with the first connecting members 6b to 8d from the four corners in the width direction of the first insulating members 8b to 8d. To the opposing insulating members 8a-8c across the 6c (the second insulating member 8a for the first insulating member 8b, the first insulating member 8b for the first insulating member 8c, and the first insulating member 8c for the first insulating member 8d). The extending connecting pieces 81 are integrally formed.

  Further, the insulating members 8a to 8c facing the first insulating members 8b to 8d (facing the second connecting terminals 6a to 6c provided with the first insulating members 8b to 8d) are in contact with the insulating members 8a to 8c. Connection grooves 82 are formed on both side surfaces to accommodate the connection pieces 81 slidably in the stacking direction. In the present embodiment, the plurality of first insulating members 8b to 8d are formed in the same shape, and the connecting groove 82 is also formed in the outermost first insulating member 8d. Moreover, in this Embodiment, the connection piece 81 and the connection groove | channel 82 were formed in the substantially rectangular shape seeing from the lamination direction.

  By forming the plurality of first insulating members 8b to 8d in the same shape, the number of parts can be reduced and the cost can be reduced, and the connecting groove 82 formed in the outermost first insulating member 8d can be formed. Utilizing this, the insulating member assembly 100 can be positioned with respect to the second terminal housing 7. In the present embodiment, the positioning protrusion 30h (see FIGS. 9 and 11) provided in the second terminal housing 7 is inserted into the connecting groove 82 of the first insulating member 8d, whereby the insulating member assembly 100 is Positioning with respect to the second terminal housing 7 is performed. In this embodiment, the positioning protrusion 30h is formed on the second inner housing 30, but it is of course possible to form it directly on the second terminal housing 7.

  The connecting piece 81 of the first insulating member 8b is connected to the connecting groove 82 of the second insulating member 8a, the connecting piece 81 of the first insulating member 8c is connected to the connecting groove 82 of the first insulating member 8b, and the connecting piece of the first insulating member 8d. By accommodating 81 in the connecting groove 82 of the first insulating member 8c, the insulating members 8a to 8d are connected in a state of being relatively movable in the stacking direction, and the insulating member assembly 100 is configured.

  Further, in the insulating member assembly 100, when the insulating members 8a to 8d are connected (stacked), the tip (upper end) of the connecting piece 81 is regulated by the upper surface of the connecting groove 82, and the insulating members 8a to 8d are spaced apart from each other. Is regulated so as not to be narrower than a predetermined interval (referred to as a minimum stacking interval).

  This minimum stacking interval is adjusted to be slightly smaller than the total thickness (referred to as contact thickness) of the first joining terminals 4a to 4c and the second joining terminals 6a to 6c constituting the contact. When the minimum stacking interval is larger than the contact thickness, the pressing force by the connection member 9 is not transmitted to the contact, and when the minimum stacking interval is too small, the second joint terminals 6a to 6c are deformed for some reason. This is because the positional deviation in the stacking direction of the insulating members 8a to 8d becomes too large, and problems such as deterioration of fitting property occur. The minimum stacking interval can be adjusted by adjusting the length difference in the stacking direction between the connecting piece 81 and the connecting groove 82 (for example, the connecting piece 81 is made longer than the length of the connecting groove 82). The minimum stacking interval will become longer.

  As shown in FIG. 14 (a), the four connecting pieces 81 of the first insulating members 8b to 8d are substantially Γ-shaped when viewed from the length direction of the second connecting terminals 6a to 6c, or are substantially horizontally reversed. It is formed in a Γ shape, and a U-shaped fitting groove 83 that opens toward the inside is formed. By inserting the second joint terminals 6a to 6c into the fitting groove 83, the first insulating members 8b to 8d are locked and fixed to the second joint terminals 6a to 6c. That is, the connecting piece 81 has both the role of connecting the insulating members 8 a to 8 d and the role of locking the second connecting terminals 6 a to 6 c, and the fitting groove 83 becomes the second terminal insertion hole 103. ing.

  On the other hand, as shown in FIGS. 1 (b) and 14 (b), when the two terminal housings 5 and 7 are fitted, the positions facing the openings of the second terminal housing 7 (the first connecting terminals 4a to 4c). The first joining terminals 4a to 4c are inserted between the connecting pieces 81 formed on the insertion side. That is, the connecting piece 81 formed at a position facing the opening of the second terminal housing 7 also serves to guide and position the tip end portions of the first connecting terminals 4a to 4c, and the second connecting terminal 6a. ˜6c and the insulating members 8a to 8c, and the opening sandwiched between the connecting pieces 81 is the first terminal insertion hole 102.

  In the present embodiment, as shown in FIGS. 14A and 14B, the plurality of first insulating members 8b to 8d are connected to the first joining terminals 4a to 4c of the second joining terminals 6a to 6c. Covering the end face and reducing the collision of the joint terminals 4a to 4c and 6a to 6c when the first joint terminals 4a to 4c are inserted between the second joint terminals 6a to 6c and the insulating members 8a to 8c. The collision reducing walls 84 are integrally formed, and chamfering (or rounding) for facilitating the insertion of the first joint terminals 4a to 4c is performed on the corners of the collision reducing walls 84. Similar chamfering (or rounding) is performed on the insulating members 8a to 8c (that is, on the side opposite to the connecting member 9 of the insulating members 8a to 8c) at the position facing the collision reducing wall 84 and the first joining terminals 4a to 4c. Is also formed at the corner on the insertion side. Although omitted in the present embodiment, the corners on the first terminal insertion hole 102 side of the connecting piece 81 may be chamfered or rounded to facilitate the insertion of the first connection terminals 4a to 4c. . The collision reducing wall 84 is formed so that the upper surface thereof is flush with the upper surfaces of the second connection terminals 6a to 6c.

  By providing the first insulating members 8 b to 8 d on the second connecting terminals 6 a to 6 c, the first insulating members 8 b to 8 d are connected to the second terminal housing 7 via the second connecting terminals 6 a to 6 c and the second inner housing 30. Thus, the first insulating members 8b to 8d are positioned with respect to the first terminal housing 5. In a state in which the first terminal housing 5 is positioned, a gap is formed between the tip of the connecting piece 81 and the upper surface of the connecting groove 82, and the first insulating members 8b to 8d move relatively in the stacking direction. It is possible. At this time, the insulating members 8a to 8d are accommodated in a space 30d surrounded by the main body 30a, the parallel part 30b, and the vertical part 30c of the second inner housing 30 (see FIGS. 9 and 11). ).

  The width of the fitting groove 83 in the stacking direction (width of the U-shaped opening) is formed slightly larger than the thickness of the second joint terminals 6a to 6c. Accordingly, when the second joining terminals 6a to 6c are fitted into the fitting groove 83, a gap (clearance) is formed between the fitting groove 83 and the second joining terminals 6a to 6c. The 1 insulating members 8b to 8d are provided with a backlash with respect to the second connecting terminals 6a to 6c. Even if the positions of the first insulating members 8b to 8d are somewhat shifted by providing the first insulating members 8b to 8d with rattling with respect to the second connecting terminals 6a to 6c, the first insulating member Since 8b-8d can move flexibly, it can reduce that fitting nature deteriorates because the 1st junction terminals 4a-4c hit the 1st insulating members 8b-8d. Further, by forming a gap (clearance) between the fitting groove 83 and the second joining terminals 6a to 6c, the second joining terminals 6a to 6c can be easily fitted into the fitting groove 83. . Although omitted in the present embodiment, in order to facilitate the fitting of the second joining terminals 6a to 6c to the fitting groove 83, the periphery of the fitting groove 83 (and the second joining terminals 6a to 6a). A chamfering process or a rounding process may be applied to the corners of the first insulating members 8b to 8d on the 6c insertion side.

  Further, in the first insulating members 8b to 8d, a connecting wall 85 is integrally formed so as to connect the two connecting pieces 81 on the opposite side to the insertion side of the second connecting terminals 6a to 6c. The connection wall 85 is provided in parallel with the insertion direction of the first connection terminals 4 a to 4 c so as to close the side opposite to the insertion side of the second connection terminals 6 a to 6 c of the fitting groove 83. In addition, the end of the second joint terminals 6a to 6c is brought into contact with the connecting wall 85, thereby reducing the positioning and over-insertion of the second joint terminals 6a to 6c. Further, the connecting wall 85 is configured to extend downward and cover the side of the connecting groove 82 opposite to the insertion side of the second joining terminals 6a to 6c, and contact when the connecting piece 81 is inserted into the connecting groove 82. The area is increased and the connection between the insulating members 8b to 8d is further stabilized. The connecting wall 85 is formed to a height that does not collide with the opposing insulating members 8a to 8c when the interval between the insulating members 8a to 8d is set to the minimum stacking interval.

  Further, as shown in FIG. 14 (b), the connecting wall 85 is located on the side of the first joint terminals 4a to 4c when the two terminal housings 5 and 7 are fitted and the first joint terminals 4a to 4c are inserted. It also plays the role of increasing the creepage distance between each contact. Such a configuration is particularly effective when the insulating members 8b to 8d are downsized and the connector 1 as a whole is downsized. In the present embodiment, when the terminal housings 5 and 7 are fitted, the first joint terminals 4a to 4c are inserted halfway without covering the entire second joint terminals 6a to 6c. This increases the creeping distance between the contacts through the side opposite to the insertion side of the first joint terminals 4a to 4c of the insulating members 8b to 8d, so that the first joint terminals of the insulating members 8b to 8d Although the connecting wall is not formed on the side opposite to the insertion side of 4a to 4c, naturally, a connecting wall is further formed on the side opposite to the insertion side of the first joining terminals 4a to 4c of the insulating members 8b to 8d. Is also possible.

  In the present embodiment, the connecting piece 81 is formed on the first insulating members 8b to 8d and the connecting groove 82 is formed on the opposing insulating members 8a to 8c. However, in the insulating member assembly 100, the connecting piece 81 and the connecting groove are formed. Of course, it is possible to reverse the relationship of 82 (the connecting piece 81 is formed on the insulating members 8a to 8c and the connecting groove 82 is formed on the opposing insulating members 8b to 8d). However, in this case, since the fitting groove 83 cannot be formed in the connecting piece 81, a mechanism for separately providing the first joining terminals 4a to 4c must be provided in the first insulating members 8b to 8d. The structure of the 1 insulating members 8b to 8d is complicated.

[Operation of this embodiment]
The operation of the present embodiment will be described.

  In connector 1 according to the present embodiment, a plurality of insulating members 8a to 8d are connected to each other, and insulation that restricts the movement in a direction perpendicular to the stacking direction of the stacked structure of insulating members 8a to 8d. Insulating member assembly 100 having member restricting means 101 is provided, and both terminal housings 5, 7 are arranged in a direction in which the length direction of first joining terminals 4a-4c and the length direction of second joining terminals 6a-6c intersect. A first terminal insertion hole 102 for inserting the first joint terminals 4a to 4c and a second terminal for inserting the second joint terminals 6a to 6c are configured to be fitted to the insulating member assembly 100. An insertion hole 103 is formed.

  By configuring the insulating member assembly 100, a force (for example, a force that pulls the cables 61a to 61c or a force that pushes the cables 61a to 61c toward the first connector portion 2) is applied to the cables 61a to 61c. However, it is possible to reduce the displacement of the insulating members 8a to 8d, and as a result, the second connecting terminals 6a to 6c abut against the insulating members 8a to 8d when the two connector portions 2 and 3 are connected. This can be reduced and the fitting operation can be performed smoothly. Further, the connector 1 is small because no holding jig is used unlike the conventional connector.

  Further, in the connector 1, the insulating member group is set so that both the terminal housings 5 and 7 are fitted in a direction in which the length direction of the first joint terminals 4 a to 4 c intersects the length direction of the second joint terminals 6 a to 6 c. Since the first terminal insertion hole 102 and the second terminal insertion hole 103 are formed in the three-dimensional body 100, the protrusion length from the device can be reduced when the device is directly connected to the device even though it is a laminated structure type, and the wiring space is effective. It becomes possible to use.

[Modification]
Next, a modified example of the present invention will be described.

  In the said embodiment, although the case where one or both of the connection piece 81 and the connection groove | channel 82 was formed in each of the four corners of the insulation members 8a-8d was demonstrated, it is not limited to this, The insulation members 8a-8d The connecting piece 81 and the connecting groove 82 may be formed at two or three of the four corners.

  When the connecting pieces 81 are formed at two positions among the four corners of the insulating members 8a to 8d, for example, the connecting pieces 81 may be formed at the opposite corners as shown in FIG. As shown in FIG. 15 (b), connecting pieces 81 may be formed at adjacent corners (not shown, but the connecting grooves 82 are formed at positions corresponding to the connecting pieces 81). ). When the connecting piece 81 and the connecting groove 82 are formed at adjacent corners as shown in FIG. 15B, the insulating members 8a to 8d can be reduced in size by the omitted connecting pieces 81 and 82, Compared with the case where the connecting piece 81 and the connecting groove 82 are formed at all four corners, the entire connector 1 can be reduced in size. Moreover, when forming the connection piece 81 in three places among the four corners of the insulating members 8a to 8d, for example, as shown in FIG. 15C, one connection piece 81 in the four corners. The connecting groove 82 is omitted. 15A to 15C, the collision reducing wall 84 and the connecting wall 85 are omitted.

  However, when the connecting piece 81 and the connecting groove 82 are formed at two or three of the four corners of the insulating members 8a to 8d, the first insulating members 8b to 8d are provided on the second connecting terminals 6a to 6c. As compared with the case where the connecting piece 81 and the connecting groove 82 are formed in all four corners, or a mechanism for guiding the first connecting terminals 4a to 4c is required separately. Since the pressing force may be biased when the connecting member 9 is pressed, it is most desirable to form the connecting piece 81 and the connecting groove 82 at all four corners of the insulating members 8a to 8d. By forming the connecting piece 81 and the connecting groove 82 at all four corners of the insulating members 8a to 8d, even when the second connecting terminals 6a to 6c are bent by pressing, the first terminal insertion hole 102 is not inclined. It is also possible to hold.

  Moreover, in the said embodiment, although the 1st insulating members 8b-8d were formed in the same shape, it is good also as a different shape. For example, the connecting piece 81 and the connecting groove 82 are formed between the insulating members 8a and 8b so that the connecting piece 81 and the connecting groove 82 are two places, and between the insulating members 8b and 8c, the connecting piece 81 and the connecting groove 82 are four places. It is also possible to change the place to do.

  Moreover, in the said embodiment, the direction in the use condition of a connector may be the connection member 9 in a substantially horizontal state, or a substantially vertical state. In other words, the usage condition of the connector in this embodiment does not require the orientation in the usage state.

  Moreover, in the said embodiment, although the adjacent 2nd insulating member 8a is pressed by the volt | bolt 9b of the connection member 9 via the elastic member 15 which is a part of the connection member 9, it does not go through the elastic member 15. Alternatively, the adjacent second insulating member 8a may be pressed directly by the bolt 9b.

  In the above embodiment, the connection member 9 is provided only on one side of the first terminal housing 5. However, the connection member 9 is provided on both sides of the first terminal housing 5, and both the sides provided on both sides are provided. You may comprise so that pressing force may be provided to each contact by the connection member 9. FIG.
