DETAILED DESCRIPTION

[0026] (First embodiment) The following will refer to Figures 1 to 10 An electrical connector according to a first embodiment of the present invention will be described.

[0027] like Figure 1 As shown, the electrical connector of this embodiment is constituted by a card edge connector 10. The card edge connector 10 includes a connector body 20 and a wire guide member 50 detachably attached to the rear of the connector body 20 in an insertion / extraction direction with respect to a printed circuit board (PCB) 100 to be connected. The wire guide member 50 guides the wire 32 extending backward from the rear end of the connector body 20 with respect to the insertion / extraction direction to be bent.

[0028] In the following description, the insertion direction of the connector body 20 relative to the PCB 100 is defined as a front-rear direction. However, this definition of the direction is only for convenience of explanation and does not limit the scope of the present invention.

[0029] The connector body 20 has a rectangular tubular connector housing 22 made of a molded plastic product. The connector housing 22 is integrally formed with a terminal receiving portion 26 that receives a plurality of terminals 24 and a rear extension portion 28 that extends rearward from a rear end of the terminal receiving portion 26. The rear extension portion 28 receives therein the rear portion of the terminal 24 received in the terminal receiving portion 26. By receiving the rear portion of the terminal 24 in the rear extension portion 28, the size of the connector body 20 can be reduced compared to a case where the rear extension portion 28 is separately configured to fit the wire guide member 50 thereto.

[0030] A pair of flanges 30 are provided at substantially middle portions in the front-rear direction on both sides of the terminal receiving portion 26 and protrude laterally outward. The flanges 30 are used by an operator when pushing the connector body 20 forward into the PCB 100.

[0031] Each terminal 24 received in the terminal receiving portion 26 and the rear extension portion 28 is configured to be electrically connected to a corresponding conductive strip 102 formed on an edge of the PCB 100 at its front end. Each wire 32 is connected to the rear of the corresponding terminal 24. Each wire 32 extends rearward from the corresponding terminal 24.

[0032] Next, we will refer to Figures 2 to 10 The details of the connector body 20 of the first embodiment are described.

[0033] The rear extension portion 28 integrally includes an upper wall 28A and a lower wall 28B extending parallel to each other, and a left wall 28C and a right wall 28D extending parallel to each other so as to form a rectangular tubular body surrounding the respective wires 32 as a whole.

[0034] The wire guide member 50 is an integrally molded member including an upper wall 50A, a left wall 50B, and a right wall 50C extending parallel to each other, and a rear wall 50D joined to rear edges of the upper wall 50A, the left wall 50B, and the right wall 50C.

[0035] The wire guide member 50 has no walls on its front side and lower side, and is open in its entire front and lower part. In other words, the front part of the wire guide member 50 opens forward, and the lower part thereof opens downward.

[0036] The front portion of the lower opening of the wire guide member 50 is referred to as a mouth portion 52 for receiving the rear extension 28 from the vertical direction. When the front portion of the wire guide member 50 receives the rear extension 28 therein, the front portions of the upper wall 50A, the left wall 50B, and the right wall 50C of the wire guide member 50 are opposed to the upper wall 28A or the lower wall 28B, the left wall 28C, and the right wall 28D of the rear extension 28, respectively.

[0037] In the following description, a state in which the rear extension portion 28 is received at the front portion of the lower wire guide member 50 or a state in which the rear extension portion 28 is received in the front portion of the lower wire guide member 50 will be referred to as a received state.

[0038] The wire guide member 50 can be used as follows Figure 2 As shown, the conductors 32 are routed downward and used as shown. Figure 4 As shown, both wires 32 are routed upward. When the wire guide member 50 is in the position shown Figure 2 When the wire 32 is routed downward as shown, the upper wall 50A, the left wall 50B, the right wall 50C and the rear wall 50D together with the rear extension 28 define a wire guide chamber 54 open at the bottom (see FIG. Figure 6 When the wire guide member 50 is in the Figure 4 When the wire 32 is routed upward as shown, the upper wall 50A, the left wall 50B, the right wall 50C and the rear wall 50D together with the rear extension 28 define a wire guide chamber 54 open at the top (see Figure 6 ).

[0039] The wire guide member 50 is vertically and laterally inverted between a state of routing the wires 32 upward and a state of routing the wires 32 downward. As a result, the left wall 50B in the state of routing the wires 32 downward becomes a side wall located on the left side, and the left wall 50B in the state of routing the wires 32 upward becomes a side wall located on the right side.

[0040] The wire guiding member 50 and the rear extending portion 28 are respectively provided with an insertion / extraction direction locking portion 56 and an insertion / extraction direction locked portion 36 for engaging the wire guiding member 50 and the rear extending portion 28 with each other in the front-rear direction in the received state.

[0041] The insertion / extraction direction locking portion 56 includes a groove 56A provided on the inner surface of each of the left wall 50B and the right wall 50C of the wire guide member 50 so as to extend linearly and vertically, and a groove 56B provided on the inner surface of the upper wall 50A so as to extend linearly in the lateral direction. The groove 56A extends along the left wall 50B and the right wall 50C over their entire vertical range, and is open at the lower edge of the left wall 50B and the right wall 50C. The grooves 56A and 56B are continuous with each other and have a door shape when viewed from the front.

[0042] The insertion / extraction direction locking portion 36 includes a ridge 36A extending vertically and linearly on the outer surface of each of the left wall 28C and the right wall 28D of the rear extension 28 to vertically slidably engage the insertion / extraction direction locking portion 56, and a ridge 36B extending linearly and laterally on the outer surface of each of the upper wall 28A and the lower wall 28B of the rear extension 28. The ridges 36A and 36B are continuous with each other and together form a continuous flange surrounding the rear extension 28, and form a rectangular frame shape when viewed from the front.

[0043] The insertion / extraction direction locking portion 56 is composed of a groove having a rectangular cross section, and the insertion / extraction direction locked portion 36 is composed of a protrusion having a rectangular cross section. The front and rear surfaces of the insertion / extraction direction locking portion 56 and the insertion / extraction direction locked portion 36 form opposing surfaces 57 and 37 that are opposed to each other in the front-rear direction (see Figure 5 The opposing surface 57 extends over the entire front and rear surfaces of the left and right grooves 56A and the upper groove 56B of the insertion / extraction direction locking portion 56, and the opposing surface 37 extends over the entire front and rear surfaces of the left and right protrusions 36A and the upper and lower protrusions 36B of the insertion / extraction direction locked portion 36.

[0044] The wire guiding member 50 is provided with a vertical direction locking portion 58 for locking the wire guiding member 50 to the rear extending portion 28 with respect to the vertical direction in the received state.

[0045] The vertical direction locking portion 58 includes a pair of elastic barbed claws that protrude from the inner surfaces of the left wall 50B and the right wall 50C of the wire guide member 50 .

[0046] The vertical direction locked portion 38 includes a pair of engagement surfaces defined by a pair of engagement recesses formed in the upper wall 28A and the lower wall 28B of the rear extension 28 so as to elastically contact (snap-fit) with the vertical direction locking portion 58. Hereinafter, the vertical direction locked portion 38 may also be referred to as a locked surface 38.

[0047] The rear extension 28 is provided with a front edge 51 that abuts against the wire guide member 50 in the receiving state (see Figure 6 ) protrusion 40. The protrusion 40 extends continuously on the outer surfaces of the upper wall 28A, the lower wall 28B, the left wall 28C and the right wall 28D of the rear extension portion 28 similarly to the insertion / extraction direction locked portion 36. In other words, the protrusion 40 forms a flange around the rear extension portion 28 and has a rectangular frame shape when viewed from the front.

[0048] like Figure 2 As shown, Figure 2 As shown, when the wire 32 is routed downward from the card edge connector 10, the wire guide member 50 with its mouth 52 facing downward is slid vertically downward from above onto the rear extension 28 of the connector body 20, so that the front portion of the wire guide member 50 is placed on the outside of the rear extension 28 through the mouth 52.

[0049] By moving wire guiding member 50 downward relative to rear extension 28 in this manner, the front portion of wire guiding member 50 receives rear extension 28 from mouth portion 52 thereof in a vertical direction orthogonal to the insertion / extraction direction.

[0050] In this receiving state, the wire 32 extending horizontally in the insertion / extraction direction from the rear end of the connector body 20 is bent downward by the wire guide member 50 by nearly 90 degrees within the wire guide chamber 54, so that the wire 32 is routed downward by the wire guide member 50 by being guided by the wire guide member 50.

[0051] When the wire guide member 50 is moved downward relative to the rear extension 28, the front edge 51 of the wire guide member 50 is kept in contact with the rear surface of the protrusions 40, 56, and the groove 56A of the insertion / extraction direction locking portion 56 slides vertically along the protrusion 36A of the insertion / extraction direction locked portion 36. As a result, the downward movement of the wire guide member 50 relative to the rear extension 28 is guided by the groove 56A and the protrusion 36A. Thus, the downward movement of the wire guide member 50 relative to the rear extension 28 can be performed smoothly and reliably.

[0052] In addition, in this receiving state, the insertion / extraction direction locking portion 56 and the insertion / extraction direction locked portion 36 engage with each other, and the wire guide member 50 is locked to the rear extension 28 in the insertion / extraction direction. In addition, in this receiving state, the vertical direction locking portion 58 elastically abuts against the corresponding locking surfaces 38 on both sides of the lower wall 28B, so that the wire guide member 50 is fixed to the rear extension 28 with respect to the vertical direction.

[0053] In this manner, in the received state, the wire guide member 50 is reliably prevented from falling off from the connector body 20 with respect to both the insertion / extraction direction and the vertical direction.

[0054] When the wire 32 is Figure 4 When wiring upward from the card edge connector 10 , the wire guide member 50 with its mouth 52 facing upward moves upward along the rear extension 28 of the connector body 20 so that the front portion of the wire guide member 50 is placed on the outside of the rear extension 28 through the mouth 52 .

[0055] By moving wire guiding member 50 upward relative to rear extension 28 in this manner, the front portion of wire guiding member 50 receives rear extension 28 from mouth portion 52 in a vertical direction orthogonal to the insertion / extraction direction.

[0056] In this receiving state, the wire 32 extending horizontally from the rear end of the connector body 20 with respect to the insertion / extraction direction is bent upward by the wire guide member 50 by nearly 90 degrees within the wire guide chamber 54, so that the wire 32 is routed upward by the wire guide member 50 by being guided by the wire guide member 50.

[0057] When the wire guiding member 50 is moved upward relative to the rear extension 28, the front edge 51 of the wire guiding member 50 is kept in contact with the rear surface of the protrusion 40, and the groove 56A of the insertion / extraction direction locking portion 56 is vertically moved in the vertical direction relative to the protrusion 36A of the insertion / extraction direction locked portion 36. As a result, the upward movement of the wire guiding member 50 relative to the rear extension 28 is guided by the groove 56A and the protrusion 36A. This allows the wire guiding member 50 to move upward relative to the rear extension 28 smoothly and reliably.

[0058] In this receiving state, the insertion / extraction direction locking portion 56 and the insertion / extraction direction locked portion 36 engage with each other, and the wire guide member 50 is locked to the rear extension 28 with respect to the insertion / extraction direction. Furthermore, in this receiving state, the vertical direction locking portion 58 elastically abuts against the corresponding locking surfaces 38 on both sides of the upper wall 28A, so that the wire guide member 50 is fixed to the rear extension 28 with respect to the vertical direction.

[0059] In this manner, in the received state, the wire guide member 50 is reliably prevented from falling off from the connector body 20 with respect to both the insertion / extraction direction and the vertical direction.

[0060] As described above, by reversing the mounting direction of the wire guiding member 50 to the connector body 20 downward or upward, the same wire guiding member 50 can be used for routing the wires 32 downward or upward, making it possible to eliminate the need to prepare two different wire guiding members 50 .

[0061] The connector body 20 can be inserted into the PCB 100 with the wire guiding member 50 pre-attached to the connector body 20 or without the wire guiding member 50 pre-attached to the connector body 20. The process of inserting the connector body 20 into the PCB 100 with the wire guiding member 50 attached to the connector body 20 can be accomplished by using a mechanical arrangement that uses the rear surface of the rear wall 50D of the wire guiding member 50 as a pressing surface when the connector body 20 is inserted into the PCB 100.
