Description

  The present disclosure relates to connectors and connector assemblies.

  Conventionally, in a wire-to-board connector for connecting an electric wire such as a cable to a circuit board such as a printed circuit board, a pair of harness housings in which the electric wires of the electric wire harness are arranged and connected in a row are coupled by a holder. A technique has been proposed in which one electric wire connector is configured and the electric wire connector is inserted into a housing of a board connector and fitted (see, for example, Patent Document 1). Thereby, the electric wires arranged in two rows can be connected to the circuit board.

  FIG. 23 is an exploded view of a conventional wire connector.

  In the drawing, reference numeral 811 denotes a pair of harness housings in which the wires 891 of the wire harness are arranged and connected in a row, and are connected by a holder 831 in a state of facing each other to constitute a wire connector. ing. Each harness housing 811 includes a plurality of terminal accommodating chambers 813, and terminals (not shown) connected to the tips of the electric wires 891 are accommodated in the terminal accommodating chambers 813.

(E) is a rear view.

  Here, as in the example shown in FIGS. 1 and 2, the front harness housing unit 11A is a combination of three harness housings 11-1, 11-2, and 11-3, whereas The case where the side harness housing unit 11B includes only a single harness housing 11-s will be described. 9B and 11B, it should be noted that the front side portion 12a of the main body portion 12 of the harness housing 11-s faces rearward (X-axis negative direction). The front harness housing unit 11A and the rear harness housing unit 11B are coupled to the front side and the rear side of the clip housing 31, as shown in FIGS.

  In addition, as described above, a part of the terminal housing recess 13 protrudes so as to face the upper end of the main body 62 of the wire side terminal 61, and the function of preventing the wire side terminal 61 from being pulled out of the terminal housing recess 13. As shown in FIGS. 7 and 8, the insertion portion 35 including the rib portion 35 a to be exhibited is integrated with the top plate portion 32 in a state of being arranged side by side in the direction of the long side of the top plate portion 32 of the clip housing 31. Connected. Therefore, the insertion part 35 and the top plate part 32 function as a retainer in which the rib part 35a prevents the electric wire side terminal 61 from coming off, and the clip housing 31 in the present embodiment is integrally formed. Including a retainer.

  In the present embodiment, the body portion 12 of the harness housing 11-α serves as a first side portion that connects the widthwise ends of the board connector 101 at the front side portion 12a, the rear side portion 12b, the upper side portion 12c, and the lower side portion 12d. Left side portion 12e and right side portion 12f as the second side portion. The left side portion 12e is formed with a connecting rib 21a protruding outward in the width direction of the board connector 101 and extending in the vertical direction. The right side portion 12f is directed inward in the width direction of the board connector 101. A connecting groove 21b that is recessed and extends in the vertical direction is formed. When combining a plurality of harness housings 11-α, the left side portion 12e and the right side portion 12f of the adjacent harness housings 11-α are opposed to each other, the connecting rib 21a is inserted into the connecting groove 21b, and the connecting rib 21a The connecting groove 21b is connected by friction. Thereby, adjacent harness housing 11- (alpha) will be in the state mutually connected. For example, in the front harness housing unit 11A, the connecting rib 21a formed on the left side 12e of the harness housing 11-1 is inserted into the connecting groove 21b formed on the right side 12f of the harness housing 11-2. The connecting rib 21a formed on the left side portion 12e of -2 is inserted into the connecting groove 21b formed on the right side portion 12f of the harness housing 11-3 and connected to each other. Regardless of the number of poles, it is desirable that the connecting rib 21a and the connecting groove 21b are formed on the left side portion 12e and the right side portion 12f of all the harness housings 11-α. Further, it is desirable that a concave groove 34b capable of accommodating the connecting rib 21a is formed at a location facing the connecting rib 21a on the inner surface of the end plate portion 34 of the clip housing 31. Since the harness housing 11-α or the clip housing 31 and the harness housing unit 11 that are connected to each other are connected by friction, they can be separated by applying a force in a direction away from each other.

  Furthermore, a convex portion 23 is formed on the left side portion 12e and the right side portion 12f of the harness housings 11-α so as to protrude outward in the width direction of the board connector 101. In addition, the protrusion amount of the convex part 23 is set smaller than the protrusion amount of the connecting rib 21a. The convex portion 23 is formed with a concave portion 23a as a void concave portion that opens to the lower side portion 12d and extends upward from the lower side portion 12d. When the left side portion 12e and the right side portion 12f of the adjacent harness housings 11-α are connected to face each other, the concave portions 23a of the left and right harness housings 11-α are combined to form a board-side terminal 161 of the board connector 101. A void space into which the contact portion 164 can enter is formed. The void space is located between the leftmost terminal accommodating recess 13 in the right harness housing 11-α and the rightmost terminal accommodating recess 13 in the left harness housing 11-α, and opens to the lower portion 12d. It is space. That is, the interval between the void space and the terminal accommodating recess 13 adjacent to the void space is the same as the pitch of the terminal accommodating recess 13 and the pitch of the board-side terminals 161. Therefore, when the harness housing unit 11 in which a plurality of harness housings 11-α are combined is inserted into the fitting space 115 of the board connector 101, the board-side terminals 161 corresponding to the connecting portions of the adjacent harness housings 11-α. The contact portion 164 enters the void space formed by the recess 23a. Thereby, even if the aspect of the combination of the harness housings 11-α is arbitrarily changed and the position of the connecting portion between the adjacent harness housings 11-α is changed, the board-side terminal 161 present at the position of the connecting portion is changed. It is possible to always use the same board connector 101 without removing it.

  Lock recesses 12g are formed on the left and right sides of the front side portion 12a of the main body portion 12 of the harness housing 11-α. Further, the main body portion rear wall 12h in the main body portion 12 is formed with one or a plurality of lock openings 24 and a slit 24a extending upward from the lock opening 24 and reaching the upper end of the main body portion rear wall 12h. Yes. The insertion receiving recess 25 communicates with the outside of the main body rear wall 12h through the lock opening 24 and the slit 24a. In the case of the harness housing 11-s having a relatively large number of poles and a relatively large dimension in the width direction (Y-axis direction) of the board connector 101, as shown in FIG. It is desirable that a support portion 25b for connecting the main body portion rear wall 12h of the main body portion 12 and the rear wall 13c of the terminal accommodating recess 13 is formed therein. By connecting the main body rear wall 12h to the rear wall 13c by the support portion 25b, it is possible to control the deflection of the main body rear wall 12h, which is a plate-like member having a spring property. In addition, the number and position of the said support part 25b are not limited to the example shown by a figure, It can change suitably.

  Next, an operation for fitting the wire connector 1 to the board connector 101 will be described.

  First, the operation | movement which comprises the harness housing unit 11 combining the some harness housing 11- (alpha), and also couple | bonds the some harness housing unit 11 to the clip housing 31, and comprises the electric wire connector 1 is demonstrated. Here, as shown in FIGS. 1 and 2, the three harness housings 11-1, 11-2, and 11-3 are combined to form the front harness housing unit 11A, and the rear harness housing unit 11B is a single unit. An example in which the front-side harness housing unit 11 </ b> A and the rear-side harness housing unit 11 </ b> B are coupled to the clip housing 31 will be described.

  The operator inserts the connecting rib 21a formed on the left side portion 12e of the harness housing 11-1 into the connecting groove 21b formed on the right side portion 12f of the harness housing 11-2 and inserts the connecting rib 21a into the left side portion 12e of the harness housing 11-2. By inserting the formed connecting rib 21a into the connecting groove 21b formed in the right side portion 12f of the harness housing 11-3, the front harness housing unit 11A as shown in FIG. 9A is configured. Further, the harness housing 11-s is used as it is as the rear harness housing unit 11B.

  Subsequently, the operator relatively raises the front harness housing unit 11 </ b> A from below the clip housing 31 and couples it to the front side of the clip housing 31. At this time, the surface of the rear side portion 12 b in the main body portion 12 of the harness housings 11-1, 11-2 and 11-3 relatively rises while sliding along the front surface of the partition wall portion 33 of the clip housing 31. Like that. Then, the base part 35b and the rib part 35a in the insertion part 35 of the clip housing 31 that descends relatively are inserted into the insertion accommodating recess part 25 and the slit 25a in the main body part 12 from above, and the rear The side portion 12b is inserted from below into the retaining rear gap 35c between the front surface of the partition wall 33 and the base portion 35b. Thereby, as shown in FIG. 2, the front harness housing unit 11 </ b> A is coupled to the front side of the clip housing 31. Similarly, the operator couples the rear harness housing unit 11 </ b> B to the rear side of the clip housing 31. Thereby, the electric wire connector 1 as shown by FIG. 2 is comprised. Since the harness housings 11-1, 11-2, and 11-3 are mounted so as to be raised with respect to the clip housing 31, and the connecting rib 21a and the connecting groove 21b are directed in the vertical direction, the harness housing 11 -1, 11-2 and 11-3 can be attached to the clip housing 31 one by one, and the operation can be selected. The harness housings 11-1, 11-2, and 11-3 are attached so as to be raised with respect to the clip housing 31. For example, the vicinity of the upper end of the rear side portion 12b is inserted into the retaining rear gap 35c. With the configuration and the configuration in which the friction lock protrusion 22 engages with the friction lock recess 33a, even one harness housing 11-α can be fixed to the clip housing 31.

  Subsequently, as shown in FIG. 2, the operator relatively lowers the electric wire connector 1 from above the board connector 101 and inserts it into the fitting space 115 of the board connector 101 to be fitted. At this time, the front side of the wire connector 1, that is, the side where the pair of polar bulges 37 are present faces the front side of the board connector 101, that is, the side where the pair of polar bulges 117 does not exist. The attitude of the electric wire connector 1 relative to the board connector 101 is controlled.

  Then, the contact part 164 of each board | substrate side terminal 161 of the board | substrate connector 101 is inserted from the downward into the corresponding terminal accommodation recessed part 13 of the main-body part 12 of harness housing 11- (alpha), and is accommodated in this terminal accommodation recessed part 13. The contact is made with the contact portion 64 of the electric wire side terminal 61 to conduct. Since the front harness housing unit 11A is configured by combining three harness housings 11-1, 11-2, and 11-3, the harness housing 11-1 and the harness housing 11-2 that are adjacent to each other are connected. As shown in FIG. 6, in the portion and the connecting portion between the harness housing 11-2 and the harness housing 11-3, there is a void space formed by combining the recesses 23 a instead of the terminal receiving recesses 13. Exists. Therefore, the contact portion 164 of the board-side terminal 161 corresponding to the connecting portion is inserted not in the terminal accommodating recess 13 but in the void space formed by the recess 23a.

  Further, the operator presses the wire connector 1 relatively downward, and engages the lock protrusion 118 in the fitting space 115 with the lock recess 38 a formed on the lock arm 38. Thereby, the electric wire connector 1 and the board | substrate connector 101 are locked in the fitted state, and unnecessary fitting cancellation | release is prevented.

  Thus, in the present embodiment, the electric wire connector 1 includes the clip housing 31 and the harness housing unit 11 coupled to the clip housing 31, and the harness housing unit 11 is provided at the end of the electric wire harness including the electric wires 91.

Can be reduced.

  Each of the harness housings 11-α includes a terminal accommodating recess 13 that accommodates an electric wire side terminal 61 connected to the terminal end of the electric wire 91. In the clip housing 31, the electric wire side terminal 61 is extracted from the terminal accommodating recess 13. The top plate part 32 and the insertion part 35 which function as a retainer which prevents this are included. Therefore, even if an external force that pulls the electric wire 91 is applied to the electric wire harness, the electric wire side terminal 61 is prevented from being pulled out from the terminal accommodating recess 13.

  Furthermore, the harness housing unit 11 is configured by connecting harness housings 11-α adjacent in the width direction. Thus, the harness housing unit 11 can be configured by arbitrarily combining the harness housing 11-α.

  Furthermore, the harness housing 11-α includes a connecting rib 21a formed on the left side portion 12e and a connecting groove 21b formed on the right side portion 12f into which the connecting rib 21a can be inserted. Therefore, the harness housings 11-α can be easily connected to each other simply by inserting the connection ribs 21a of the harness housing 11-α adjacent to the connection grooves 21b of the harness housing 11-α.

  Furthermore, the harness housing 11-α includes a convex portion 23 formed on the left side portion 12e and the right side portion 12f, and a concave portion 23a formed on the convex portion 23, and adjacent harness housings 11-α connected to each other. Between the left side portion 12e and the right side portion 12f, a void space into which the board-side terminal 161 can enter is formed by the concave portion 23a. Thereby, even if the aspect of the combination of the harness housings 11-α is changed and the position of the connecting portion between the adjacent harness housings 11-α is changed, the board-side terminal 161 present at the position of the connecting portion is changed to the board connector. The board connector 101 having the same specification can always be used without being removed from the board 101.

  Furthermore, the clip housing 31 includes a partition wall 33 extending in the width direction, and the harness housing unit 11 is coupled to both sides of the partition wall 33. Therefore, a large number of electric wire harnesses can be integrated into one electric wire connector 1.

  Furthermore, a friction lock recess 33a is formed in the partition wall 33, and the friction lock protrusions 22 formed on the harness housing 11-α included in the harness housing unit 11 on both sides of the partition wall 33 engage with the friction lock recess 33a. As a result, the friction lock protrusion 22 and the friction lock recess 33 a cooperate with the top plate portion 32 and the insertion portion 35 that function as a retainer, so that the harness housing unit 11 is reliably coupled to the clip housing 31.

  Furthermore, the clip housing 31 includes end plate portions 34 connected to both ends of the partition wall 33, and a lock arm including a lock recess 38 a that can engage with the lock protrusion 118 of the board connector 101 on the outer surface of the end plate portion 34. 38 is formed.
