Note that when the harness base unit 11 is combined with the clip base 31, the lower end of the partition wall 33 further protrudes downward relative to the lower side portion 12d of the harness base 11-α, and when the wire connector 1 is fitted in In the state of the fitting space 115, the lower end of the partition wall 33 is inserted into the bottom plate 112 of the base 111 Formed in the groove 112a.

In addition, the insertion portions 35 are arranged in a row at the same pitch as the pitch of the terminal accommodating recesses 13 in the width direction of the harness base 11-α (that is, in the direction of the long side of the top plate portion 32). Each insertion portion 35 includes: an elongated strip-shaped base portion 35b extending downward; and a rib portion 35a extending downwardly from the center of the width direction (Y-axis direction) of the base portion 35b opposite to the direction of the partition wall 33 protrude. Note that the lower end of the base 35b further protrudes downward relative to the lower end of the rib 35a. In addition, the insertion portion 35 is formed at a distance from the front and rear surfaces of the partition wall 33, and a holding rear gap 35c is formed between the front and rear surfaces of the partition wall 33 and the base 35b. As shown in FIGS. 4A and 5, in a state where the wire harness base unit 11 and the clip base 31 are combined, the insertion portion 35 is positioned to correspond to each terminal accommodating recess 13. The vicinity of the upper end of the rear side portion 12b of the harness base 11-α is then inserted into the holding rear gap 35c, and the vicinity of the lower end of the base portion 35b is inserted into the insertion groove 25c of the receiving recess 25. The rib 35 a is inserted into the slit 25 a so that at least a part of the rib 35 a protrudes into the terminal accommodating recess 13. The portion protruding into the lower end of the rib 35a in the terminal accommodating recess 13 is located above the upper end 62c of the main body 62 of the wire-side terminal 61 accommodated in the terminal accommodating recess 13, and therefore, prevents the wire-side terminal 61 from being received from the terminal Pull out from the recess 13.

That is, the base 35b of the insertion portion 35 is inserted into the insertion accommodating recess 25, while the friction locking protrusion 22 is engaged with the friction locking recess 33a, so that the harness base unit 11 is attached to the clip base 31, and at the same time, The rib 35a serves as a retainer to prevent the wire-side terminal 61 from being pulled out of the terminal receiving recess 13.

Note that in this embodiment, the rib 35a is inserted into the slit 25a as a holding member, so that a part of the rib 35a protrudes into the terminal accommodating recess 13, but in order to make the wire harness base unit 11 and The clamping base 31 is combined, and the holding member structure can be arranged in other ways to form a structure without the rib 35a and the rear wall 13c.

Next, the configuration of the wire connector 1 will be described in detail.

Fig. 8 is a perspective view of a clamping base of the connector in the first embodiment. 9A and 9B are perspective views of a harness base unit of the connector in the first embodiment.

Note that, in FIGS. 9A and 9B, FIG. 9A is a perspective view as viewed from the front side harness base unit, and FIG. 9B is a perspective view as viewed from a rear side harness base unit. In FIGS. 11A and 11B, FIG. 11A is a perspective view of a wire harness base with a small number of poles, and FIG. 11B is a perspective view of a wire harness base with a large number of poles. In FIGS. 12A to 12E and 13A to 13E, FIGS. 12A and 13A are front views, FIGS. 12B and 13B are top views, FIGS. 12C and 13C are bottom views, and FIGS. 12D and 13D are Side view, and Figure 12E, Figure 13E is a rear view.

Here, it will be explained that the front harness base unit 11A in the example shown in FIGS. 1 and 2 is a combination of three harness bases 11-1, 11-2, 11-3, and the rear harness base unit 11B includes Only a single harness base 11-s case. It should be noted that in FIGS. 9B and 11B, the front side portion 12a of the body portion 12 of the wire harness base 11-s faces rearward (negative X-axis direction). In addition, as shown in Figure 6 and Figure 7, the front wiring harness The base unit 11A and the rear side harness base unit 11B are coupled to the front side and the rear side of the clip base 31.

Note that, as described above, the plurality of insertion portions 35 (all have a part protruding into the terminal accommodating recess 13 to face the upper end of the main body portion 62 of the wire-side terminal 61 and include functions to prevent the wire-side terminal 61 from being received from the terminal The ribs 35a) for the function of pulling out the recess 13 are integrally formed with the top plate 32, and are arranged in the direction of the two long sides of the top plate 32 of the base 31, as shown in FIGS. 7 and 8. Therefore, the insertion portion 35 and the top plate portion 32 are configured such that the rib 35a functions as a retaining member for preventing the wire-side terminal 61 from being pulled out, and the clamping base 31 in this embodiment includes an integrally formed retaining member. Pieces.

In this embodiment, the body portion 12 of the wire harness base 11-α includes a left side portion 12e as a first side portion and a right side portion 12f as a second side portion. 12b and the upper side portion 12c and the lower side portion 12d are connected to both ends in the width direction of the board connector 101. A connecting rib 21a that protrudes to the outside in the width direction of the substrate connector 101 and extends in the vertical direction is formed on the left side portion 12e, and is recessed toward the inside of the substrate connector 101 in the width direction and extends in the vertical direction. A connecting groove 21b is formed on the right side portion 12f. In order to combine the plurality of harness bases 11-α, the left side portion 12e and the right side portion 12f of the adjacent wire harness base 11-α face each other and the connecting rib 21a is inserted into the connecting groove 21b to connect the connecting rib 21a and The grooves 21b are connected by friction. As a result, the adjacent harness bases 11-α are connected to each other. For example, in the front harness base unit 11A, the connecting rib 21a formed on the left side 12e of the harness base 11-1 is inserted into the connecting groove 21b formed on the right side 12f of the harness base 11-2, and the wire The coupling rib 21a formed on the left side portion 12e of the harness base 11-2 is inserted into the coupling groove 21b formed on the right side portion 12f of the harness base 11-3, so that the three harness bases are coupled to each other. Note that regardless of the number of poles, the connecting rib 21a and the connecting groove 21b are preferably formed on the left side 12e of all the harness bases 11-α And the right part 12f. In addition, a groove 34b in which the connecting rib 21a can be received is preferably formed at a position opposite to the connecting rib 21a on the inner surface of the end plate portion 34 of the clamping base 31. Since the plurality of wire harness bases 11-α or the clip base 31 and the wire harness base 11 connected to each other are connected by friction, they can be separated by a force applied in a direction that moves and separates these components from each other.

In addition, the convex portions 23 protruding to the outside in the width direction of the board connector 101 are formed on the respective left side portion 12e and right side portion 12f of the wire harness base 11-α. Note that the protrusion amount of the convex portion 23 is set to be smaller than the protrusion amount of the connecting rib 21a. A concave portion 23 a that is a void concave portion that opens toward the lower side portion 12 d and extends upward from the lower side portion 12 d is formed in the convex portion 23. When the corresponding left side portion 12e and right side portion 12f of adjacent wire harness bases 11-α are connected while facing each other, the concave portions 23a of the left and right wire harness bases 11-α are combined with each other, which results in the formation of the substrate connector 101 An empty space into which the contact portion 164 of the substrate-side terminal 161 (ie, terminal) can be inserted. The empty space is a space between the leftmost terminal receiving recess 13 of the right harness base 11-α and the rightmost terminal receiving recess 13 of the left harness base 11-α, and the space It opens toward the lower side 12d. In other words, the distance between the empty space and the adjacent terminal accommodating recesses 13 is the same as the distance between the terminal accommodating recesses 13 and the board-side terminal 161. Thus, when a harness base unit 11 including a combination of a plurality of harness bases 11-α is inserted into the fitting space 115 of the board connector 101, the board-side terminal 161 and the adjacent harness base 11- The contact portion 164 corresponding to the corresponding connecting portion of α enters the empty space formed by the recessed portion 23a. As a result, even if the combination of the plurality of harness bases 11-α changes as needed and the positions of the corresponding connection portions of the adjacent harness bases 11-α change, the same substrate connector 101 can always be used, It is not necessary to remove the substrate-side terminal 161 at the position of the coupling portion.

In addition, the locking recesses 12g are formed on the left and right sides of the front side portion 12a of the main body portion 12 of the wire harness base 11-α. In addition, one or more locking openings 24 and a gap 24a extending upward from the locking opening 24 and reaching the upper end of the body portion rear wall 12h are formed in the body portion rear wall 12h. The insertion and receiving recess 25 communicates with the outside of the rear wall 12h of the main body via the lock opening 24 and the slit 24a. Note that, in the case where a harness base 11-s has a relatively large number of poles and a relatively large size in the width direction (Y-axis direction) of the substrate connector 101, as shown in FIG. 13B, use A supporting portion 25 b that connects the body portion rear wall 12 h of the body portion 12 and the rear wall 13 c of the terminal accommodating recess 13 is preferably formed in the insertion accommodating recess 25. By connecting the main body rear wall 12h to the rear wall 13c via the supporting portion 25b, the bending of the main body rear wall 12h as a flat element with elastic properties can be controlled. Note that the number and positions of the support portions 25b are not limited to the examples shown in the figure and may be appropriately changed.

Next, the operation of fitting the wire connector 1 and the board connector 101 will be described.

First, it will be described how to form a wire harness base unit 11 by combining a plurality of wire harness bases 11-α, and to further form a wire connector 1 by combining a plurality of wire harness base units 11 to a clamping base 31. action. Here, it will be described that a front-side harness base unit 11A as shown in FIGS. 1 and 2 is formed by combining three harness bases 11-1, 11-2, and 11-3, and a rear-side harness base unit 11B An example in which only a single harness base 11-s is formed, and the front harness base unit 11A and the rear harness base unit 11B are combined with a clip base 31.

By inserting the connecting rib 21a formed on the left part 12e of the harness base 11-1 into the connecting groove 21b formed on the right part 12f of the harness base 11-2, the left side of the harness base 11-2 The connecting rib 21a formed on the portion 12e is inserted into the connecting rib formed on the right side portion 12f of the harness base 11-3. In the knot 21b, the operator forms a front-side harness base unit 11A such as that shown in FIG. 9A. In addition, the harness base 11-s directly serves as a rear harness base unit 11B.

Next, the operator relatively raises the front harness base unit 11A from below the clip base 31 and couples the front harness base unit 11A to the front side of the clip base 31. At this time, the surface of the rear side portion 12b of the body portion 12 corresponding to the harness bases 11-1, 11-2, 11-3 relatively rises while sliding along the front surface of the partition wall 33 of the clamping base 31. The base 35b and the rib 35a of the insertion portion 35 of the clip base 31 that are relatively lowered are inserted into the insertion and accommodation recess 25 and the gap 25a of the main body 12 from above, and the rear side portion 12b is inserted into the front of the partition wall 33 from below. The rear gap 35c is retained between the surface and the base 35b. As a result, as shown in FIG. 2, the front side harness base unit 11A is combined with the front side of the clip base 31. In addition, the operator similarly couples the rear side harness base unit 11B to the rear side of the clip base 31. As a result, a wire connector 1 such as that shown in FIG. 2 is constructed. The harness bases 11-1, 11-2, 11-3 are attached to rise relative to the clip base 31 and the connecting ribs 21a and the connecting groove 21b face up and down. Therefore, the harness bases 11-1, 11 -2, 11-3 can each be attached to a single clamping base 31, which can select the job. Note that the configuration in which the harness bases 11-1, 11-2, 11-3 are attached to rise relative to the clip base 31 is a configuration in which even a single harness base 11-α penetrates, for example, the rear side A structure in which the vicinity of the upper end of the portion 12b is inserted to hold the rear gap 35c and a structure in which the friction locking protrusion 22 engages with the friction locking recess 33a can be fixed to the clamping base 31.

Next, as shown in FIG. 2, the operator lowers the wire connector 1 relative to the board connector 101 from above and inserts the wire connector 1 into the fitting space 115 of the board connector 101 to fit the board connector 101. At the same time, the position of the wire connector 1 relative to the substrate connector 101 is controlled to be the wire connector 1 The front side (that is, the side where the pair of bulging portions 37 for polarity exists) faces the front side of the board connector 101 (that is, the side where the pair of bulging portions 117 for polarity does not exist).

As a result, the contact portion 164 of each board-side terminal 161 of the board connector 101 is inserted from below into the corresponding terminal accommodating recess 13 of the main body portion 12 of the harness base 11-α and interacts with the wire-side terminal 61 accommodated in the terminal accommodating recess 13 The contact portion 64 is in contact for conduction. Note that because the front harness base unit 11A is constructed by combining three harness bases 11-1, 11-2, 11-3, the adjacent harness base 11-1 and harness base 11-2 There is an empty space formed by the combination of the recess 23a instead of the terminal accommodating recess 13, as shown in Fig. 6 Show. Therefore, the contact portion 164 of the board-side terminal 161 corresponding to the connecting portion is inserted into an empty space formed through the recessed portion 23 a instead of being inserted into the terminal accommodating recessed portion 13.

In addition, the operator relatively depresses the wire connector 1 and engages the locking protrusion 118 in the fitting space 115 with the locking recess 38 a formed in the locking arm 38. As a result, the fitted state of the wire connector 1 and the board connector 101 is locked, which prevents unnecessary release of the fitting.

Therefore, in the present embodiment, the wire connector 1 includes a clamping base 31 and a wire harness base unit 11 combined with the clamping base 31, wherein the wire harness base unit 11 includes the wires 91 A plurality of wire harness bases 11-α connected to the ends of the wire harness. As a result, a plurality of wire harnesses can be integrated into one connector 1 to reduce the number of components, reduce the amount of work required for mating the wire connector 1 and the board connector 101, and reduce the manufacturing cost.

In addition, each harness base 11-α includes a terminal accommodating recess 13 for accommodating the wire-side terminal 61 connected to the end of the wire 91, and the clamping base 31 includes a top plate portion 32 And an insertion portion 35, which serves as a holding member for preventing the wire-side terminal 61 from being pulled out from the terminal receiving recess 13. Therefore, even if an external force that pulls the wire 91 is applied to the wire harness, it is possible to prevent the wire-side terminal 61 from being pulled out from the terminal accommodating recess 13.

In addition, the wire harness base unit 11 is formed by coupling the wire harness bases 11-α adjacent to each other in the width direction. As a result, the wire harness base 11-α can be combined as necessary to form a wire harness base unit 11.

In addition, each harness base 11-α includes a connecting rib 21a formed on the left side 12e and a connecting groove 21b into which the connecting rib 21a formed on the right side 12f can be inserted. Thus, by simply inserting the connecting rib 21a of one harness base 11-α into the connecting groove 21b of an adjacent harness base 11-α, the plurality of harness bases 11-α can be easily connected to each other.

In addition, the harness base 11-α includes a convex portion 23 formed on both the left side portion 12e and the right portion 12f and a concave portion 23a formed on the convex portion 23. The concave portion 23a between the corresponding left side portion 12e and right side portion 12f forms an empty space into which the board-side terminal 161 can enter. As a result, even if the form of the combination of the plurality of harness bases 11-α changes and the positions of the corresponding connection portions of the adjacent harness bases 11-α change, one board connector 101 having the same specification can always be used , Without removing the board-side terminal 161 at the position of the coupling portion from the board connector 101.

In addition, the clamping base 31 includes a partition wall 33 extending in the width direction, and a plurality of harness base units 11 are respectively combined with both sides of the partition wall 33. Thus, multiple wire harnesses can be integrated into a single wire connector 1.

In addition, friction lock recesses 33a are formed in the partition wall 33, and friction lock protrusions 22 that engage with the friction lock recesses 33a are formed on the harness base 11-α included in the harness base unit 11 on both sides of the partition wall 33. As a result, the friction lock protrusion 22 and the friction lock recess 33a are engaged with the top plate portion 32 and the insertion portion 35 as a holder, so that the harness base unit 11 is reliably combined with the clip base 31.

In addition, the clip base 31 includes an end plate portion 34 connected to both ends of the partition wall 33, and the locking arm 38 includes a locking recess 38a formed on the outer surface of the end plate portion 34, and the locking recess 38a can be connected to the substrate The locking protrusion 118 of 101 is engaged. As a result, the fitted state of the wire connector 1 and the board connector 101 is locked, which prevents unnecessary release of the fitting.

Next, a second embodiment will be explained. Note that the description of the objects having the same configuration as the first embodiment is omitted by being represented by the same symbols. In addition, the description of the same actions and effects as the first embodiment will also be omitted.

This embodiment is suitable for the case where a plurality of wire harness bases 11-α of the first embodiment are commonly used and arranged in a row in the width direction to form a single wire harness base unit 11. However, this is a specific configuration, which The problem to be solved is: when a harness base unit 11 in which multiple harness bases are arranged in a row is used for a single connector and there are multiple harnesses connected to the circuit board, it is necessary to prepare multiple wire connectors And a plurality of substrate connectors, which not only increases the number of components, but also increases the amount of work required for mating the wire connector and the substrate connector, resulting in an increase in manufacturing costs.

The symbol 201 is a wire connector, as a connector of this embodiment, which is connected to the end of a wire harness including a plurality of wires 91 like the wire connector 1 in the first embodiment. However, the wire connector 1 of the first embodiment has two wire harness base units 11 in which the ends of the wires 91 arranged in the width direction of the two rows are connected, while the wire connector 201 of this embodiment includes a single row The ends of the wires 91 arranged in the width direction are connected to a harness base unit 11.

In addition, 301 is a substrate connector, as a mating connector in this embodiment, mounted on a circuit substrate as a substrate (not shown). The wire connector 201 and the substrate connector 301 can be fitted with each other to form the connector assembly of this embodiment. It should be noted that the substrate connector 301 is a so-called straight connector, which is erected relative to a circuit substrate (that is, with the opening facing upwards). Install. The wire connector 201 is vertically fitted with the board connector 301, and as a result, the wire 91 is drawn out perpendicular to the circuit board.

In addition, in this embodiment, the expressions such as up, down, left, right, front, and back for explaining the operation and structure of each member of the wire connector 201 and the board connector 301 are not absolute but not absolute. In contrast, and although these indications are appropriate when the wire connector 201 and the substrate connector 301 are in the orientation shown in the figure, when these orientations change, the orientation of the wire connector 201 and the substrate connector 301 should correspond These changes are explained variably.

The substrate connector 301 is a connector called a joint connector, which is made of an insulating material such as a synthetic resin, and includes: a base 311 as a mating connector body, integrally formed and connected with wires And a plurality of substrate-side terminals 161, as mating terminals, made of conductive metal plates, attached to pass through a bottom plate portion 312 of the base 311. The base 311 has a direction orthogonal to the mating direction (Z-axis direction) of the wire connector 201 and a direction extending in the arrangement direction of the board-side terminals 161 (that is, the width direction (Y-axis direction) of the board connector 301). A box-shaped element that is roughly a cuboid.

A terminal insertion hole (not shown) penetrating the bottom plate portion 312 is formed in the bottom plate portion 312, and the substrate-side terminal 161 is inserted into the terminal insertion hole to be attached to the bottom plate portion 312. Note that the board-side terminal 161 is the same as the board-side terminal 161 in the first embodiment.

In addition, in the example shown in the figure, a total of ten substrate-side terminals 161 are arranged in a row at a predetermined pitch in the width direction of the substrate connector 301. However, the number of substrate-side terminals 161 (ie, the number of poles) and the substrate The pitch of the side terminals 161 can be changed as needed.

The base 311 includes: a flat bottom plate portion 312 having a substantially rectangular shape in plan view; a pair of side plate portions 313 extending along the two long sides of the bottom plate portion 312 and extending upward from the bottom plate portion 312; a pair of end plates 314, extending along the two short sides of the bottom plate 312 and extending upward from the bottom plate 312; and a fitting space 315, defined by the bottom plate 312, a pair of side plate parts 313, and a pair of end plate parts 314 on five sides while facing the bottom plate The upper part of section 312 is open. The wire connector 201 is inserted into the fitting space 315 and fitted. Note that, in the fitting space 315, the contact portions 164 of the plurality of board-side terminals 161 protruding upward (in the positive Z-axis direction) from the bottom plate portion 312 are arranged in a row.

In addition, attachment nails 371 as reinforcing metal fittings are attached to the end plate portion 314. The nail tail 372 formed at the lower end of the attachment nail 371 is fixed to a connection pad or the like (not shown) formed on the surface of the circuit substrate by soldering or the like. In addition, the locking arm 373 serves as a friction locking element, is wrapped around the upper end of the end plate portion 314 and extends into the fitting space 315, and is connected to the upper end of the attachment nail 371. The lock arm 373 is a cantilever-type leaf spring element, the upper end of which is fixed as a base end and the end 373a of which is a free end extending downward. A locking protrusion 374 protruding toward the center of the width direction of the substrate connector 301 is formed between the upper end and the distal end 373a. The locking protrusion 374 enters and engages with the locking recesses 12g formed on the left and right sides of the front side portion 12a of the main body portion 12 of the harness base 11-α of the wire connector 201. Note that the upwardly extending lock restricting protrusion 317 is formed on the upper surface of the bottom plate portion 312 near the end plate portion 314, and the distal end 373a of the lock arm 373 is accommodated in the lock between the lock restricting protrusion 317 and the end plate portion 314. Restrict the inside of the recess 318. As a result, the position of the locking protrusion 374 in the width direction of the substrate connector 301 is restricted.

In addition, a plurality of friction lock protrusion receiving grooves 319 extending in the vertical direction are formed on the surface of the side plate portion 313 on the rear side on the side of the fitting space 315. When the wire connector 201 is inserted into the mating space 315 Inside, the friction locking protrusion 22 formed on the rear side portion 12b of the harness base 11-α of the wire connector 201 is received in the friction locking protrusion receiving groove 319. Note that the tapered portion 316 is formed on the surface on the side of the fitting space 315 near the upper end of the side plate portion 313 on the front and rear sides. The tapered portion 316 is an inclined surface formed as the size of the fitting space 315 gradually increasing toward the upper end surface of the base 311, and serves a guiding function for smoothly guiding the wire connector 201 into the fitting space 315.

On the other hand, the wire connector 201 includes: a wire harness base unit 11 as a combined body; a holder 231 to which the wire harness base unit 11 can be coupled to the holder 231; and a plurality of wire side terminals 61 as terminals, It is connected to the vicinity of the ends of the plurality of wires 91.

In this embodiment, as in the first embodiment, the wire harness base unit 11 may be a combination of a plurality of wire harness bases 11-α or may include only a single wire harness base 11-α. That is, a single wire harness base 11-s can be directly used as a wire harness base unit 11, as shown in FIG. 15, or a wire harness base unit 11 can pass through three wire harness bases 11-1, 11-2, The combination of 11-3 is constructed, as shown in Figure 16. Here, for convenience of description, a case where a single wire harness base 11-s is directly used as a wire harness base unit 11 will be described.
