Description

Technical Field

[0001] The invention relates to the technical field of wiring harness terminal processing, and in particular to a wiring harness terminal plastic part and a plug-in shell fixing device. Background Art

[0002] The wire harness terminal crimping assembly plastic shell refers to crimping the wire harness and the terminal (spring) and assembling them into the plastic shell. Through the plastic shell, the terminal can be fixed in it according to a certain spacing and arrangement, so as to facilitate the connection and management of the circuit. At the same time, the plastic shell can also provide additional protection to prevent the terminal from being damaged or failed due to external factors (such as dust, moisture, etc.). Specifically, it can be operated by machine or manually, or by machine and manual operation.

[0003] The existing integrated machine for crimping and assembling wire harness terminals and plastic shells can meet the operations of cutting wires, stripping, riveting terminals, and inserting plastic shells. The riveting equipment and shell inserting equipment can load terminals and plastic shells. In addition, the mechanical fixture (manipulator) can move the wire harness and move the wire harness to the riveting equipment and shell inserting equipment for installation, thereby completing a series of operations. However, when inserting shells into wiring harnesses, that is, wire harnesses tightly connected between wires, if several plastic shells are split structures, after the shells are inserted, the ends of the wire harnesses are relatively messy and it is not easy to perform subsequent processing such as silk screen printing. If several plastic shells are connected structures, when the shells are inserted by the machine, since the plastic shells have a certain width, the wires on the outside need to be distorted to a certain extent before the shells can be inserted, and this will affect the shell insertion effect and the yield rate. Manually inserting the shells one by one is less efficient.

[0004] Therefore, the present invention provides a wiring harness terminal plastic component and a plug shell fixing device to solve the above problems. Summary of the invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a wiring harness terminal plastic part and a plug-in shell fixing device to solve the above-mentioned problem that when a wiring harness, i.e., a wiring harness with closely connected wires, is plugged in, if some plastic shells are split structures, after the plug-in is completed, the end of the wiring harness is relatively messy and it is not easy to perform subsequent processing such as silk screen printing. If some plastic shells are connected structures, when the shell is plugged in by a machine, since the plastic shell has a certain width, the wire located on the outside needs to be distorted to a certain extent before the shell can be completed, and it will affect the plug-in effect and the yield rate. Manually plugging in the shells one by one is inefficient.

[0006] In order to achieve the above object, the technical solution adopted by the present invention is:

[0007] A plastic part for a wire harness terminal, comprising an arc-shaped chute, on which a number of plug-in parts are slidably arranged, and a fixing part is fixedly arranged. It also includes a number of plastic shells. On one side of the number of plastic shells close to the arc-shaped chute, there are jacks. One of the number of plastic shells is fixedly and detachably connected to the arc-shaped chute through the jack and the fixing part, and the rest of the plastic shells are inserted into the arc-shaped chute through the jacks and the plug-in parts. The wire insertion ends of the number of plastic shells face the concave side of the arc-shaped chute. An elastic connecting rib is arranged between adjacent plastic shells. In the natural state, the plastic shell fixedly and detachably connected to the arc-shaped chute through the fixing part is fixed relative to the arc-shaped chute, and the rest of the plastic shells are positioned under the action of the elastic connecting rib. All the plastic shells are parallel to each other. When the rest of the plastic shells are stressed, they slide along the arc-shaped chute.

[0008] Preferably, the fixing part is a threaded pin.

[0009] Preferably, the elastic connecting rib includes an elastic rubber section and connecting sections located at both ends of the elastic rubber section. The cross-section of the connecting section is in the shape of a "T". In the natural state, the connecting sections at both ends are close to and touch each other under the action of the elastic rubber section.

[0010] Preferably, the inner ends of the connecting sections are made of magnetic materials.

[0011] Preferably, the plastic shell is arranged on the top of the arc-shaped chute.

[0012] An insertion shell fixing device, comprising a support plate. At the front side near the top of the support plate, there is an arc-shaped positioning part adapted to the plastic part for the wire harness terminal. A pushing mechanism is arranged behind the arc-shaped positioning part. The pushing mechanism includes a first pushing part and a second pushing part. The first pushing part is used to push the plastic part for the wire harness terminal and cooperate with the arc-shaped positioning part to position and clamp the plastic part for the wire harness terminal. The second pushing part is used to push the plastic shell on the plastic part for the wire harness terminal to move.

[0013] Preferably, the first pushing part is in the shape of a flat plate. A first telescopic part is arranged at the rear side of the first pushing part. The second pushing part is arranged at the rear side of the first telescopic part. A second telescopic part is arranged at the rear side of the second pushing part. During operation, first control the second telescopic part to extend, driving the second pushing part, the first telescopic part and the first pushing part to move forward together until the plastic part for the wire harness terminal is clamped by the first pushing part and the arc-shaped positioning part. Then continue to control the second telescopic part to extend, and at the same time control the first telescopic part to shorten, driving the second pushing part to approach the plastic part for the wire harness terminal and push the plastic shell to move.

[0014] Preferably, the first telescopic part includes a first rod body fixedly connected to the first pushing part and a second rod body fixedly connected to the second pushing part. The first rod body and the second rod body are slidably connected and are provided with a limiting spring. The second pushing part is an electric telescopic rod fixedly arranged on the support plate.

[0015] Preferably, the second pusher includes an "L"-shaped plate, and a plurality of push plates are inclinedly arranged on the "L"-shaped plate.

[0016] Preferably, a mounting member is provided on the "L"-shaped plate, and the push plate is detachably arranged on the "L"-shaped plate through the mounting member and the mounting position can be adjusted.

[0017] The beneficial effects of the present invention are as follows:

[0018] 1. The wire harness terminal plastic part of the present invention includes a plurality of plastic shells, and the plastic shells can slide along the arc-shaped chute as needed. When in use, before inserting the wire harness with the terminals connected into the plastic shell, the plastic shell can be controlled to move slightly and be positioned so that the wire insertion end of the plastic shell corresponds to the wire harness terminal end. Thus, when inserting the shell, it is beneficial for the wire harness terminal to be accurately inserted into the plastic shell. After the jacking is completed, the plastic shell is no longer positioned. Under the action of the elastic connecting ribs, each plastic shell returns to a parallel state. In this state, it is convenient to perform processing such as silk screening on a plurality of plastic shells. After the processing is completed, cut between adjacent plastic shells and remove the arc-shaped chute. The present invention has accurate shell insertion, high efficiency, and is convenient for subsequent processing.

[0019] 2. After the arc-shaped chute of the wire harness terminal plastic part of the present invention is disassembled, it can be reused, and the utilization rate is high.

[0020] 3. When the shell insertion fixing device of the present invention is in use, only need to reasonably move the wire harness terminal plastic part between the first pusher and the arc-shaped positioning part, and then by controlling the movement of the pushing mechanism, the wire harness terminal plastic part can be positioned and clamped by the first pusher and the arc-shaped positioning part, and the plastic shell on the wire harness terminal plastic part is pushed by the second pusher to finally position the wire harness terminal plastic part, which is convenient for subsequent shell insertion operation.

[0031] Next, each embodiment of the present invention will be described in detail with reference to the attached Figures 1 to 9 Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0032] A wire harness terminal plastic part, as shown in the attached Figure 1 , Figure 2 , Figure 3As shown, it includes an arc-shaped slide groove 1, the concave side of the arc-shaped slide groove 1 faces forward, and a plurality of plug-ins 5 are slidably provided along the top of the arc-shaped slide groove 1, and a fixing piece 4 is fixedly provided. In this embodiment, there are five plug-ins 5, three of which are located on the left side of the fixing piece 4, and two are located on the right side of the fixing piece 4. It also includes a plurality of plastic shells 2. In this embodiment, a total of six plastic shells 2 are provided. The six plastic shells 2 are close to one side of the arc-shaped slide groove 1, that is, the bottom of the plastic shell 2 is provided with a plug hole 6, one of the plastic shells 2 is fixedly and detachably connected to the arc-shaped slide groove 1 through the plug hole 6 and the fixing piece 4, and is usually kept in a fixed state with the arc-shaped slide groove 1, and the remaining five plastic shells 2 are plugged into the arc-shaped slide groove 1 through the plug hole 6 and the plug-in 5, three One is located on the left side of the fixed plastic shell 2, and two are located on the right side of the fixed plastic shell 2. The ones on the left side are two one-pin and two two-pin, and the ones on the right side are two two-pin. The wire plug ends of the six plastic shells 2 are facing the concave side of the arc-shaped slide groove 1, that is, facing the front side. Elastic connecting ribs 3 are provided between adjacent plastic shells 2. The elastic connecting ribs 3 can be stretched when subjected to external force, and can maintain a certain shape when not subjected to force. In a natural state, the plastic shell 2 that is detachably connected to the arc-shaped slide groove 1 by the fixing member 4 is fixed relative to the arc-shaped slide groove 1, and the remaining plastic shells 2 are positioned under the action of the elastic connecting ribs 3. At this time, all the plastic shells 2 are parallel to each other. When the remaining plastic shells 2 are subjected to force, they can slide along the arc-shaped slide groove 1.

[0033] During specific use, in a natural state, all plastic shells 2 are parallel to each other, which is convenient for silk-screen processing and other operations on multiple plastic shells 2 as a whole; before inserting the shell, it is only necessary to slide the corresponding plastic shell 2 slightly outward to position it, that is, the plastic shell 2 on the left side slides to the left along the arc-shaped slide groove 1, and the plastic shell 2 on the right side slides to the right along the arc-shaped slide groove 1, so that it can adapt to the position of the cable end, so as to facilitate the overall guidance of the cable end into the plastic shell 2 for shell insertion, thereby effectively improving work efficiency; after the shell insertion is completed, the elastic connecting rib 3 is cut off by a cutter, and the fixed plastic shell 2 is separated from the fixing part 4, and the arc-shaped slide groove 1 is removed, that is, the entire operation is completed, and the removed arc-shaped slide groove 1 can also be reused.

[0034] In addition, it should be noted that, in the present invention, since the positions of the various plastic shells 2 on the arc-shaped slide groove 1 are different, the insertion holes 6 arranged at the bottom of the various plastic shells 2 are also slightly different.

[0035] In addition, it should be noted that the elastic connecting ribs 3 between the plastic shells 2 in the present invention can be made by thermoplastic technology, the arcuate slide 1 and the plastic shell 2 can be manually installed, and an elastic reset member can also be arranged between the plug-in 5 on the arcuate slide 1 and the arcuate slide 1. When not subject to external force, the plug-in 5 and the fixing member 4 correspond to the positions of the corresponding plastic shells 2, which is convenient for quick installation. In addition, the specific specifications and quantity of the plastic shells 2 can be customized as needed, and the number of the plug-ins 5 on the arcuate slide 1 can also be set as needed, which is more flexible to use.

[0036] As shown in the appended Figure 2 and Figure 4 shown, in this embodiment, the fixing member 4 is a threaded pin, and the jack 6 of the relative fixed rubber shell 2 is a threaded hole. A threaded hole adapted to the threaded pin is provided on the arc-shaped sliding groove 1 for stable fixation. In addition, it should be noted that in the attached drawing, in order to facilitate the observation of the fixing member 4, after the fixing member 4 is fixed, the bottom of the fixing member 4 is lower than the arc-shaped sliding groove 1, which may cause the situation that it cannot be placed stably. During the actual production process, support blocks can also be provided at both ends of the bottom of the arc-shaped sliding groove 1, so that it is convenient to install and disassemble the fixing member 4 and can keep the arc-shaped sliding groove 1 placed stably after the fixing member 4 is installed.

[0037] As shown in the appended Figure 1 and Figure 4 and Figure 5 shown, in this embodiment, the elastic connecting rib 3 includes an elastic rubber section 302 and connecting sections 301 located at both ends of the elastic rubber section 302. Tensile and reset are generated through the elastic rubber section 302, and the connecting section 301 is connected to the rubber shell 2. The cross-section of the connecting section 301 is in a "T" shape and is connected to the elastic rubber section 302 and the rubber shell 2 through the outer end, which can ensure the stretching in the middle of the elastic rubber section 302. In the natural state, the connecting sections 301 at both ends are close to and touch each other under the action of the elastic rubber section 302, so as to ensure the parallel state of multiple rubber shells 2 in the natural state. In addition, it should be noted that in this embodiment, when cutting the elastic connecting rib 3, it can be easily cut by cutting the connecting section 301.

[0038] In this embodiment, the inner end of the connecting section 301 is made of a magnetic material, and the two ends in contact of the two connecting sections 301 are respectively provided with positive and negative magnetic sheets, that is, the two ends in contact of the two connecting sections 301 can be attracted and fixed, and the parallel state between the rubber shells 2 is further ensured when no external force is applied.

[0039] An insertion shell fixing device, as shown in the appended Figure 6 and Figure 8 and Figure 9 shown, includes a support plate 7. An arc-shaped positioning member 8 adapted to the wire harness terminal plastic part is provided near the front side of the top of the support plate 7, that is, the concave side of the arc-shaped positioning member 8 faces forward, and the outer diameter of the arc-shaped positioning member 8 is equivalent to the inner diameter of the arc-shaped sliding groove 1. A pushing mechanism is provided behind the arc-shaped positioning member 8. The pushing mechanism includes a first pushing member 9 and a second pushing member 11. The first pushing member 9 is used to push the wire harness terminal plastic part and cooperate with the arc-shaped positioning member 8 to position and clamp the wire harness terminal plastic part. The second pushing member 11 is used to push the rubber shell 2 on the wire harness terminal plastic part to move.

[0040] Working principle: When the plastic part of the wire harness terminal is placed between the first pusher 9 and the arc-shaped positioning part 8, and the concave side of the arc-shaped chute 1 faces roughly forward, control the first pusher 9 to move forward until the first pusher 9 contacts the arc-shaped chute 1 and pushes the arc-shaped chute 1 forward until the arc-shaped chute 1 contacts the arc-shaped positioning part 8 and is positioned under the action of the arc-shaped positioning part 8. At this time, determine the position of the arc-shaped chute 1, and then control the movement of the second pusher 11 until the second pusher 11 contacts the plastic housing 2 and pushes the plastic housing 2 to move, so that the wire insertion ends of several plastic housings 2 form a certain arc, thus adapting to the position of the end of the wire arrangement and facilitating the guiding of the wire insertion of the end of the wire arrangement. After the wire insertion is completed, the first pusher 9 and the second pusher 11 can be reset.

[0041] In specific use, when the present invention is in specific use, a feeding device such as a vibrating disk and a conveyor belt is arranged on one side of the support plate 7, which can roughly control the feeding position of the plastic part of the wire harness terminal. After positioning the plastic part of the wire harness terminal and controlling the movement of several plastic housings 2, the wire arrangement after riveting the terminals is moved to the position of the plastic part of the wire harness terminal by a mechanical fixture (manipulator), and then the wire insertion can be carried out. This part of the structure is the prior art and will not be elaborated here.

[0042] In this embodiment, the first pusher 9 is in the shape of a flat plate, that is, when the plastic part of the wire harness terminal is placed on the support plate 7, the height of the first pusher 9 is lower than that of the plastic housing 2, so that the first pusher 9 can smoothly contact the arc-shaped chute 1 without being affected by the plastic housing 2 and push the arc-shaped chute 1 to move. A first telescopic member 10 is provided at the rear side of the first pusher 9, the second pusher 11 is arranged at the rear side of the first telescopic member 10, and a second telescopic member 12 is provided at the rear side of the second pusher 11. During operation, first control the second telescopic member 12 to extend, driving the second pusher 11, the first telescopic member 10 and the first pusher 9 to move forward together until the plastic part of the wire harness terminal is clamped by the first pusher 9 and the arc-shaped positioning part 8 to realize the positioning of the arc-shaped chute 1. Then continue to control the second telescopic member 12 to extend, and at the same time control the first telescopic member 10 to shorten, driving the second pusher 11 to approach the plastic part of the wire harness terminal and push the plastic housing 2 to move, so as to realize the control of the movement of the plastic housing 2. In this embodiment, the position of the plastic housing 2 can be finally controlled by the extension and contraction of the second telescopic member 12 and the first telescopic member 10, with a simple structure and convenient use.

[0043] As shown in the attached Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 As shown in the figure, in this embodiment, the first telescopic member 10 includes a first rod body 1002 fixedly connected to the first pusher 9 and a second rod body 1001 fixedly connected to the second pusher 11. The first rod body 1002 and the second rod body 1001 are slidably connected and are provided with a limiting spring 1003. The second telescopic member 12 is an electric telescopic rod fixedly arranged on the support plate 7.

[0044] Working principle: In the natural state, under the action of the limiting spring 1003, the relative position between the first rod body 1002 and the second rod body 1001 remains unchanged, so that the length of the first telescopic member 10 remains unchanged. The second telescopic member 12 is an electric telescopic rod, which can be externally connected to a controller and its telescopic movement can be controlled electrically. During operation, the second telescopic member 12 first extends, driving the second pusher 11, the first telescopic member 10, and the first pusher 9 to move forward together until the arc-shaped chute 1 of the wire harness terminal plastic part is positioned by the first pusher 9 and the arc-shaped positioning member 8. During this process, the length of the first telescopic member 10 always remains unchanged. After positioning the arc-shaped chute 1, then as the second telescopic member 12 continues to extend, the first rod body 1002 and the second rod body 1001 will approach each other against the elasticity of the limiting spring 1003, thereby driving the second pusher 11 to approach the wire harness terminal plastic part until it contacts the plastic shell 2 and drives the plastic shell 2 to move. During resetting, the first rod body 1002 and the second rod body 1001 are reset under the action of the limiting spring 1003.

[0045] In this embodiment, only by controlling the movement of the second telescopic member 12, the movement of the first pusher 9 and the second pusher 11 can be controlled. The structure is simple, easy to use, and convenient for repair.

[0046] In this embodiment, the second pusher 11 includes an "L"-shaped plate 1101. The "L"-shaped structure facilitates the connection with the electric telescopic rod of the second telescopic member 12. A number of push plates 1103 are inclinedly arranged on the "L"-shaped plate 1101. When the second pusher 11 moves forward, it drives the push plates 1103 to move forward. When the push plates 1103 contact the plastic shell 2, they push the plastic shell 2 to move, causing the plastic shell 2 to move along the arc-shaped chute 1. The plastic shell 2 is kept balanced under the action of both the push plates 1103 and the elastic connecting ribs 3, thereby realizing the positioning of the plastic shell 2.

[0047] In this embodiment, a mounting member 1102 is provided on the "L"-shaped plate 1101. The push plates 1103 are detachably arranged on the "L"-shaped plate 1101 through the mounting member 1102, and the mounting position can be adjusted. Specifically, a number of slots are provided on the mounting member 1102, and the push plates 1103 are inserted into the mounting member 1102 through the slots. Through multiple slots, the number and position of the push plates 1103 can be flexibly adjusted, so as to be applicable to wire harness terminal plastic parts of multiple different specifications.
