Description

  The present invention relates to a relay connector, and more particularly, to a relay connector used to electrically connect a pair of connectors.

Relay connectors are often used in automobile electrical wiring and the like. In many cases, this relay connector is used by inserting its body into a mounting hole of various electrical component units mounted on an automobile transmission or the like.

  This relay connector has a bracket attached to its lower part and is mounted at a predetermined location. In consideration of the positional deviation between the electrical component unit and this relay connector when mounted, Usually, some backlash is provided between the brackets in the up / down, left / right, and front / rear directions. However, since the connector to which the terminals of a number of wire groups are connected is inserted into the relay connector from below, the connector is pushed upward by the tension applied from the wire group, and the fixing becomes unstable. In addition, as described above, the play is provided in the left and right and front and rear directions, so that it may be inclined obliquely by the play and the tension from below, and when inserted and fixed in the mounting hole of the electrical component unit, FIG. As shown in FIG. 3, the relay connector 28 is greatly disengaged from the guide taper 27 of the insertion hole 26 provided in the electrical component unit 25, and it may not be possible to guide it well. In the figure, 29 is an electric wire. In this way, if the relay connector 28 is forcibly attached with insufficient guidance, damage or failure will be caused during use. Therefore, the orientation is corrected so that the insertion hole 26 is invited. Although it is necessary, the correction work in a small installation place is actually quite difficult. In some cases, the relay connector attached to the bracket is turned upside down and attached to the electrical component unit. However, depending on the shape of the electrical component unit, it may be difficult to correct the orientation of the relay connector.

  In order to avoid such a situation, it is effective to adopt a so-called floating structure in which the relay connector can move slightly in the vertical and horizontal directions and the front and rear directions with respect to the bracket, but it protrudes greatly from the bracket. In the floating structure, it interferes with other parts and members located outside, so that the mounting location is limited and there is a possibility that versatility is significantly impaired. Furthermore, in the floating structure, it is essential to provide a mechanism that suppresses the displacement of the member more than expected, that is, an anti-over mechanism, in order to prevent the member from being damaged, but this also requires a large space. However, it has also been a cause of impairing versatility. As a result of diligent research to solve the above-described conventional problems related to the relay connector, the present inventor can maintain the floating state of the relay connector main body in the up-down, left-right, and front-back directions, that is, the floating state. Nevertheless, we succeeded in developing a relay connector with excellent versatility that is compact and does not protrude greatly from the bracket and does not interfere with externally located parts and members. It is what we propose.

  It has a cylindrical shape, and connectors are inserted into the inside from the upper and lower opening ends, respectively, and a connector body 1 for relay made of synthetic resin that electrically connects between these connectors, a pair of side plates 17, 17 and the side plates 17, A relay connector comprising a metal mounting bracket 16 having a substantially U-shaped cross section composed of a beam member 18 connecting between the end edges of 17 and mounting the relay connector body 1 to a desired external location; A pair of planar side wall portions 2a and 2b whose one side edges are in contact with each other at a right angle are integrally formed at the lower outer periphery of the relay connector main body 1, and at the upper ends of these planar side wall portions 2a and 2b. A flange 3 projecting in an overhanging direction is integrally formed, and one planar side wall 2 a has the same projecting width as the collar 3, and the upper edge 4 is the lower surface of the flange 3. Center, rear edge Are in contact with the center of the planar side wall portion 2a, and have a T-shaped cross section with a small thickness from the upper edge to the central portion in the longitudinal direction, and a prismatic cross section with a large thickness from the central portion to the lower end. A rib-shaped guide plate 9 having a step 8 formed thereon, extending from the lower front end of the guide plate 9 in the left-right direction, and the open-side end bent to the rear side in a substantially U shape, A first bracket receiving member 12 comprising an elastic floating support member 11 provided with an anti-over plate 10 having a rectangular shape opposite to the end edge thereof is provided on the other planar side wall portion 2b. Is slightly extended outward from the outer side, then bent inward at a substantially right angle, and further bent so as to be parallel to the planar side wall portion 2b, and from the back surface of the parallel portion. Planar side wall 2b Floating support members 24 on which anti-over pieces 13 are suspended toward each other integrally form second bracket receivers 15 that face each other with their open side edges facing each other, The mounting bracket 16 has a pair of tongue-like inserts 20 and 20 each having a hook-shaped locking part 19 formed on the head, and the beam material so that the locking parts 19 and 19 face each other. The first fixing member 21 planted from the center of the upper edge 18 and the second fixing member 22 in the shape of a tongue extending upward from the center of the upper edge of one side plate 17 are integrally formed. By inserting the first fixing member 21 of the mounting bracket into the first bracket holder 12 of the relay connector body 1 and the second fixing member 22 into the second bracket holder 15, Relay connector The above-mentioned problem has been solved by allowing the main body 1 to be mounted on the mounting bracket 16 in a floating state.

  A floating mechanism is constituted by the first bracket receiver 12 and the second bracket receiver 15 that are separately provided at positions displaced by 90 °. As shown in FIG. 8, the first bracket receiver 12 12, the first fixing member 21 of the mounting bracket 16 is inserted into the first bracket 21 of the mounting bracket 16, and the first fixing member 22 of the mounting bracket 16 is inserted into the second bracket receiver 15 of the relay connector body 1 as shown in FIG. At this time, the key-shaped locking portion 19 of the insertion member 20 constituting the first fixing member 21 is engaged with the step 8 of the guide plate 9, and from now on, Although it is prevented from detaching, sliding in the up and down direction, that is, the direction of the arrow Z in FIGS. 6 and 8 is allowed in a range until it comes into contact with the flange portion 3 along the upper step portion 6. Further, the outer side edge of the insertion member 20 abuts against the anti-over piece 13 of the floating support member 11 when moved to the left and right, but the floating support member 11 has elasticity, so the insertion member 20 is elastically supported in the left-right direction, that is, in the direction of the arrow X in FIGS. 6 and 8 while the swing range is restricted by the floating support material 11. Furthermore, since the both side edges of the second fixing member 22 of the mounting bracket 16 are located between the anti-over pieces 13 and 13 facing each other of the second bracket receiver 15 of the relay connector main body 1, When it swings back and forth, it comes into contact with the anti-over pieces 13 and 13 and is thereby elastically supported while restricting the swing range in the front-rear direction, that is, in the direction of the arrow Y in FIGS. It will be.

  In this way, the relay connector body 1 is supported by the mounting bracket 16 so as to be slidable in the vertical direction, swingable in the left-right and front-back directions, and elastically supported. Even if an unexpected tension is applied, it is possible to continue to acquire the correct spatial position opposite to this, and it is possible to always mount it in the correct position without greatly departing from the lead-in taper of the electrical component unit. Become. Therefore, when the relay connector main body is mounted on an automobile transmission or the like, a predetermined position in the electrical component unit is always maintained, and damage or failure due to a defect in the mounting position can be prevented. In addition, since the first bracket metal fitting 12 and the second bracket receiving member 15 constituting the floating structure are provided separately at two positions displaced by 90 °, the members constituting the floating structure are provided on the relay connector main body 1. It does not protrude greatly outside the outer periphery, is very compact, and can be installed in a narrow place where space is limited. Furthermore, the first bracket receiver 12 and the second bracket receiver 15 are also used for absorbing the positional deviation between the electrical component unit and the relay connector main body and for improving the mounting performance. Since the floating structure is sufficiently secured, there is no need to provide these backlashes separately, which has the effect of improving workability and facilitating mounting work, and has high practical value.

  The maximum is at the point where the relay connector body is mounted in a state where it can be slid in the vertical direction and can be swung in the horizontal direction and in the front-rear direction in an elastically floating state at two positions displaced by 90 ° with respect to the mounting bracket. There are features.

FIG. 7 is a side view thereof, and FIG. 8 is a front view of the relay connector main body mounted on the mounting bracket.
In the figure, reference numeral 1 denotes a relay connector main body, which is made of synthetic resin, has a cylindrical shape, and has a function of inserting connectors (not shown) from the upper and lower open ends to connect the connectors electrically. Have A pair of planar side wall portions 2a and 2b whose one side edges are in contact with each other at a right angle are integrally formed at the lower outer periphery of the relay connector main body 1, and these planar side wall portions 2a and 2b are integrally formed. At the upper end of each, a flange portion 3 projecting in an overhang shape toward the outside is integrally formed. The planar side wall 2a has the same overhang width a as the flange 3, and the upper end 4 is at the center of the lower surface of the flange 3, and the rear edge 5 is at the center of the planar side edge 2a. As shown in FIG. 8, the upper step 6 having a T-shaped cross section with a small thickness b from the upper end to the central portion in the longitudinal direction, and the lower step portion having a prismatic cross section with a large thickness c from the central portion to the lower end. 7, a rib-shaped guide plate 9 having a step 8 formed at the center is integrally provided. The lower end of the guide plate 9 is formed in a tapered shape so that the mounting bracket 16 can be easily inserted. Further, a strip-shaped member is symmetrically and integrally extended in the left-right direction at the front end edge of the lower portion of the guide plate 9, and the open-side end edge is bent toward the rear side in a substantially U-shape. In addition, a floating support member 11 having elasticity, in which an anti-over plate 10 having a rectangular shape is opposed to each end edge, is integrally formed. The guide plate member 9 and the floating support member 11 constitute a first bracket receiver 12.

  The other planar side wall 2b has a strip shape, is slightly extended outward from the surface thereof, then bends inward substantially at a right angle, and is further parallel to the planar side wall 2b. The anti-over pieces 13 and 13 having a rectangular shape are suspended from the back surface of the parallel portion toward the planar side wall portion 2b, and have an elastic floating support. A second bracket receiver 15 in which the material 24 is positioned so as to face each other with the open side edges 14 and 14 facing each other is integrally formed.

  On the other hand, reference numeral 16 denotes a mounting bracket, which is made of metal and has a substantially U-shaped cross section comprising a pair of side plates 17 and 17 and a beam member 18 that integrally connects these end edges as shown in FIG. In the center of the upper edge of the beam member 18, a pair of tongue-shaped inserts 20 each having a key-shaped locking part 19 formed at the head are respectively connected to the locking parts 19, 19. A first fixing member 21 that is positioned so as to face each other with an interval smaller than the wall thickness c and larger than the wall thickness b is integrally planted. A second fixing member 22 having a simple tongue shape is integrally formed from the center of the upper edge of one side plate 17. The width d of the second fixing member 22 is set to be smaller than the interval e between the anti-over pieces 13 and 13.

  The relay connector main body 1 and the mounting bracket 16 according to the first embodiment each have the above-described configuration, and the first bracket receiver 12 and the second bracket separately provided at positions displaced by 90 °. As shown in FIG. 8, the first fixing member 21 of the mounting bracket 16 is attached to the first bracket receiver 12 as shown in FIG. The second fixing member 22 of the mounting bracket 16 is inserted into the second bracket receiver 15 of the relay connector main body 1 to couple them together. At this time, the key-shaped locking portion 19 of the insertion member 20 constituting the first fixing member 21 engages with the step 8 of the guide plate 9 and is prevented from being separated therefrom. 6 is allowed to slide in the vertical direction, that is, in the direction of the arrow Z in FIGS. Further, the outer side edge of the insertion member 20 abuts against the anti-over piece 13 of the floating support member 11 when swung from side to side. However, since the floating support member 11 has elasticity, it is inserted. The material 20 is elastically supported in the left-right direction, that is, in the direction of the arrow X in FIGS. 6 and 8 while the swing range is restricted by the floating support material 11. Furthermore, since the both side edges of the second fixing member 22 of the mounting bracket 16 are located between the anti-over pieces 13 and 13 facing each other of the second bracket receiver 15 of the relay connector main body 1, When it swings back and forth, it comes into contact with the anti-over pieces 13 and 13, and this strongly supports it while restricting the swing range in the front-rear direction, that is, in the direction of arrow Y in FIGS. 6 and 7. Will be.

  Therefore, the relay connector main body 1 is supported by the mounting bracket 16 so as to be slidable in the vertical direction, swingable in the left-right and front-back directions, and elastically supported by the group of electric wires inserted into the relay connector main body 1. Even if an unexpected tension is applied, it is possible to keep the correct spatial position opposite to this, and it is possible to always mount it in the correct position without greatly deviating from the lead-in taper of the electrical component unit. . Therefore, when the relay connector main body is mounted on an automobile transmission or the like, a predetermined position in the electrical component unit is always maintained, and damage or failure due to a defect in the mounting position can be prevented. In addition, since the first bracket receiver 12 and the second bracket receiver 15 constituting the floating structure are provided separately at two positions displaced by 90 °, the members constituting the floating structure are the relay connector main body 1. It is very compact and can be installed in a narrow space where space is limited. Furthermore, the play required for absorbing the displacement between the electrical component unit and the relay connector main body and the play provided for improving the mounting property are also constituted by the first bracket receiver 12 and the second bracket receiver 15. Since the floating structure is sufficiently secured, there is no need to provide these backlashes separately, which has the effect of improving workability and facilitating mounting work, and has high practical value.

  The present invention is not limited to the field of automobiles and can be used for mounting various electrical components.
