Description

Technical Field

[0001] This invention relates to the field of wire harness terminal processing technology, and specifically to a wire harness terminal plastic part and a housing fixing device. Background Technology

[0002] The wire harness terminal crimping assembly housing refers to crimping the wire harness to the terminal (spring) and assembling it into the housing. The housing allows the terminal to be fixed in a certain spacing and arrangement, which facilitates circuit connection and management. At the same time, the housing also provides additional protection to prevent the terminal from being damaged or malfunctioning due to external factors (such as dust, moisture, etc.). Specifically, it can be done by machine or manually, or by machine in combination with manual operation.

[0003] Existing wire harness terminal crimping and shell assembly machines can perform operations such as wire cutting, stripping, crimping terminals, and inserting shells. The crimping and shell insertion equipment can feed terminals and shells, and the additional mechanical clamps (robotic arms) can move the wire harness to the crimping and shell insertion equipment for installation, thus completing a series of operations. However, when inserting shells into ribbon cable harnesses, i.e., wire harnesses with tightly connected wires, if the shells are separate structures, the wire harness ends are relatively messy after insertion, making it difficult to perform subsequent processing such as screen printing. If the shells are connected structures, the outer wires need to be distorted to a certain extent when inserting shells by machine because the shells have a certain width, which affects the insertion effect and the yield. Manually inserting shells one by one is inefficient.

[0004] Therefore, the present invention provides a plastic part for a wire harness terminal and a housing fixing device to solve the above problems. Summary of the Invention

[0005] To address the above issues and overcome the shortcomings of existing technologies, this invention provides a wire harness terminal plastic part and a housing fixing device. This solves the problem that when inserting housings into ribbon cable harnesses (i.e., tightly connected wire harnesses), if the housings are separate structures, the wire harness ends are messy after insertion, making subsequent processing such as screen printing difficult. If the housings are integrated structures, machine insertion requires the outer wires to bend to a certain extent due to the housing's width, affecting the insertion effect and yield. Manual insertion, one by one, is inefficient.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A wire harness terminal plastic part includes an arc-shaped groove, on which a plurality of inserts are slidably disposed and fixedly disposed by a fixing member. It also includes a plurality of plastic shells, each with an insertion hole near the side of the arc-shaped groove. One of the plastic shells is detachably connected to the arc-shaped groove via the insertion hole and the fixing member, while the remaining plastic shells are inserted into the arc-shaped groove via the insertion holes and inserts. The insertion ends of the plastic shells face the concave side of the arc-shaped groove. Elastic connecting ribs are provided between adjacent plastic shells. In its natural state, the plastic shell detachably connected to the arc-shaped groove via the fixing member is fixed relative to the arc-shaped groove, while the remaining plastic shells are positioned by the elastic connecting ribs. All plastic shells are parallel to each other. When the remaining plastic shells are subjected to force, they slide along the arc-shaped groove.

[0008] Preferably, the fastener is a threaded pin.

[0009] Preferably, the elastic connecting rib includes an elastic rubber segment and connecting segments located at both ends of the elastic rubber segment. The cross-section of the connecting segment is "T" shaped. In a natural state, the connecting segments at both ends approach each other and touch each other under the action of the elastic rubber segment.

[0010] Preferably, the inner end of the connecting section is made of magnetic material.

[0011] Preferably, the rubber shell is positioned at the top of the arc-shaped groove.

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

[0013] Preferably, the first pusher is flat, and a first telescopic member is provided on the rear side of the first pusher. The second pusher is located on the rear side of the first telescopic member, and a second telescopic member is provided on the rear side of the second pusher. During operation, the second telescopic member is first controlled to extend, driving the second pusher, the first telescopic member, and the first pusher to move forward together until the plastic part of the wire harness terminal is clamped by the first pusher and the arc-shaped positioning member. Then, the second telescopic member is controlled to extend further, while the first telescopic member is controlled to shorten, driving the second pusher to approach the plastic part of the wire harness terminal and pushing the plastic shell to move.

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

[0015] Preferably, the second pusher includes an "L"-shaped plate, and the "L"-shaped plate is provided with a plurality of push plates arranged at an angle.

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

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

[0018] 1. The plastic component of the wire harness terminal in this invention includes multiple housings, and the housings can slide along the arc-shaped groove as needed. During use, before inserting the wire harness with the connected terminals into the housing, the housing can be slightly moved and positioned so that the insertion end of the housing corresponds to the end of the wire harness terminal. This facilitates the precise insertion of the wire harness terminal into the housing. After insertion, the housing is no longer positioned, and each housing returns to a parallel state under the action of the elastic connecting ribs. In this state, it is convenient to perform screen printing and other processing on multiple housings. After processing, the adjacent housings are cut off and the arc-shaped groove is removed. This invention provides accurate housing insertion, high efficiency, and facilitates subsequent processing.

[0019] 2. The arc-shaped groove of the plastic part of the wire harness terminal in this invention can be reused after disassembly, resulting in high utilization rate.

[0020] 3. In the present invention, when the insert fixing device is in use, it is only necessary to move the plastic part of the wire harness terminal reasonably between the first pusher and the arc-shaped positioning member. Then, by controlling the movement of the pushing mechanism, the plastic part of the wire harness terminal can be positioned and clamped by the first pusher and the arc-shaped positioning member. The second pusher pushes the plastic shell on the plastic part of the wire harness terminal to move, and finally positions the plastic part of the wire harness terminal, which is convenient for subsequent inserting operation.

[0031] The following will refer to the attached reference. Figures 1 to 9 The various embodiments of the present invention will be described in detail below. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] A type of plastic terminal for wire harnesses, as shown in the attached document. Figure 1 , Figure 2 , Figure 3As shown, the device includes an arc-shaped slide 1 with its concave side facing forward. Several inserts 5 are slidably mounted along the top of the arc-shaped slide 1, and a fixing member 4 is fixedly mounted thereon. In this embodiment, there are five inserts 5 in total, three located to the left of the fixing member 4 and two located to the right. It also includes several plastic shells 2, six in total in this embodiment. The six plastic shells 2 are located near the side of the arc-shaped slide 1, i.e., at the bottom of the bottom of the plastic shell 2, and have insertion holes 6. One plastic shell 2 is detachably connected to the arc-shaped slide 1 via the insertion hole 6 and the fixing member 4, and normally remains fixed to the arc-shaped slide 1. The other five plastic shells 2 are inserted into the arc-shaped slide 1 via the insertion holes 6 and the inserts 5. One shell 2 is located on the left side of the fixed shell 2, and two shell 2 are located on the right side of the fixed shell 2. The shell 2 on the left side has two one-pin and two two-pin connectors, and the shell 2 on the right side has two two-pin connectors. The connector ends of the six shell 2 face the concave side of the arc-shaped slide groove 1, that is, the front side. There is an elastic connecting rib 3 between adjacent shell 2. The elastic connecting rib 3 can be stretched when subjected to external force and can maintain a certain shape when not subjected to force. In the natural state, the shell 2 that is detachably connected to the arc-shaped slide groove 1 by the fixing part 4 is fixed relative to the arc-shaped slide groove 1. The remaining shell 2 is positioned under the action of the elastic connecting rib 3. At this time, all shell 2 are parallel to each other. When the remaining shell 2 is subjected to force, it can slide along the arc-shaped slide groove 1.

[0033] In practical use, under natural conditions, all the shells 2 are parallel to each other, which facilitates the overall screen printing and other operations on multiple shells 2. Before inserting the shell, the corresponding shell 2 only needs to be slid outward slightly for positioning, that is, the shell 2 on the left slides to the left along the arc-shaped slide 1, and the shell 2 on the right slides to the right along the arc-shaped slide 1, so as to match the position of the ribbon cable end, thereby facilitating the overall guidance of the ribbon cable end into the shell 2 for insertion, which can effectively improve work efficiency. After the shell is inserted, the elastic connecting rib 3 is cut with a cutter, and the fixed shell 2 is separated from the fixing part 4. The arc-shaped slide 1 is removed, thus completing the entire operation. The removed arc-shaped slide 1 can also be reused.

[0034] Additionally, it should be noted that, due to the different positions of each rubber shell 2 on the arc-shaped groove 1, the insertion holes 6 provided at the bottom of each rubber shell 2 are also slightly different.

[0035] Additionally, it should be noted that the elastic connecting ribs 3 between the plastic shells 2 in this invention can be produced using a thermoplastic process. The arc-shaped slide 1 and the plastic shell 2 can be installed manually. An elastic reset component can also be provided between the plug-in 5 on the arc-shaped slide 1 and the arc-shaped slide 1. When there is no external force, the plug-in 5 and the fixing component 4 correspond to the corresponding positions of the plastic shell 2, which facilitates quick installation. Furthermore, the specific specifications and quantity of the plastic shell 2 can be customized as needed, and the number of plug-in 5 on the arc-shaped slide 1 can also be set as needed, making the use more flexible.

[0036] As attached Figure 2 , Figure 4 As shown, in this embodiment, the fixing member 4 is a threaded pin, and the insertion hole 6 of the fixing shell 2 is a threaded hole. The arc-shaped slide 1 is provided with a threaded hole that matches the threaded pin, which facilitates stable fixing. In addition, it should be noted that, in order to facilitate the observation of the fixing member 4 in the attached figure, after the fixing member 4 is fixed, the bottom of the fixing member 4 is lower than the arc-shaped slide 1, which may cause the situation that it cannot be placed stably. In the actual production process, support blocks can also be set at both ends of the bottom of the arc-shaped slide 1, so that the fixing member 4 can be installed and disassembled, and the arc-shaped slide 1 can be kept stably placed after the fixing member 4 is installed.

[0037] As attached Figure 1 , Figure 4 , Figure 5 As shown, in this embodiment, the elastic connecting rib 3 includes an elastic rubber segment 302 and connecting segments 301 located at both ends of the elastic rubber segment 302. The elastic rubber segment 302 generates tension and reset, and the connecting segments 301 connect to the rubber shell 2. The cross-section of the connecting segment 301 is "T" shaped. The outer end is connected to the elastic rubber segment 302 and the rubber shell 2, which can ensure the tension of the middle part of the elastic rubber segment 302. In the natural state, the connecting segments 301 at both ends are close to each other and touch each other under the action of the elastic rubber segment 302, thereby ensuring 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, the connecting segments 301 can be cut, which can easily complete the cutting.

[0038] In this embodiment, the inner end of the connecting segment 301 is made of magnetic material, and the contact ends of the two connecting segments 301 are respectively made of positive and negative magnetic sheets, that is, the contact ends of the two connecting segments 301 can be attracted and fixed, further ensuring the parallel state between the shells 2 when no external force is applied.

[0039] A housing fixing device, as shown in the attached Figure 6 , Figure 8 , Figure 9 As shown, the device includes a support plate 7. The top of the support plate 7 near the front is provided with an arc-shaped positioning member 8 that is adapted to the plastic part of the wire harness terminal. 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 slide 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 plastic part of the wire harness terminal and cooperate with the arc-shaped positioning member 8 to position and clamp the plastic part of the wire harness terminal. The second pushing member 11 is used to push the plastic shell 2 on the plastic part of the wire harness terminal 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 groove 1 is roughly facing forward, the first pusher 9 is controlled to move forward until it contacts the arc-shaped groove 1 and pushes the arc-shaped groove 1 forward until it contacts the arc-shaped positioning part 8 and is positioned under the action of the arc-shaped positioning part 8. At this time, the position of the arc-shaped groove 1 is determined. Then, the second pusher 11 is controlled to move until it contacts the plastic shell 2 and pushes the plastic shell 2 to move, so that the insertion ends of several plastic shells 2 form a certain arc, thereby adapting to the position of the end of the ribbon cable and facilitating the guidance of the insertion shell of the end of the ribbon cable. After the insertion shell is completed, the first pusher 9 and the second pusher 11 are reset.

[0041] In practical use, the present invention has a feeding device, such as a vibratory plate and a transmission belt, on one side of the support plate 7. This device can roughly control the feeding position of the wire harness terminal plastic parts. After positioning the wire harness terminal plastic parts and controlling the movement of several plastic shells 2, the cable after riveting the terminal is moved to the wire harness terminal plastic parts by a mechanical clamp (robotic arm), and then the shells can be inserted. This part of the structure is existing technology and will not be described in detail here.

[0042] In this embodiment, the first pusher 9 is flat, meaning that 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 the height of the plastic shell 2. This allows the first pusher 9 to smoothly contact the arc-shaped slide groove 1 without being affected by the plastic shell 2, and to push the arc-shaped slide groove 1 to move. A first telescopic member 10 is provided behind the first pusher 9, and a second pusher 11 is located behind the first telescopic member 10. A second telescopic member 12 is provided behind the second pusher 11. During operation, the second telescopic member 12 is first controlled to extend, driving the second pusher 11 and the first telescopic member 10 to move. The retractable part 10 and the first pusher 9 move forward together until the wire harness terminal plastic part is clamped by the first pusher 9 and the arc-shaped positioning part 8, thereby positioning the arc-shaped slide groove 1. Then, the second telescopic part 12 is extended while the first telescopic part 10 is shortened, which drives the second pusher 11 to approach the wire harness terminal plastic part and pushes the plastic shell 2 to move, thereby controlling the movement of the plastic shell 2. In this embodiment, the position of the plastic shell 2 can be finally controlled by the extension and retraction of the second telescopic part 12 and the first telescopic part 10. The structure is simple and easy to use.

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

[0044] Working principle: In its natural state, the first rod 1002 and the second rod 1001 are kept in a constant relative position by the limiting spring 1003, thus keeping the length of the first telescopic member 10 constant. The second telescopic member 12 is an electric telescopic rod that can be connected to an external controller for electrical control of its extension and retraction. During operation, the second telescopic member 12 extends first, which in turn drives the second pusher 11, the first telescopic member 10, and the first pusher 9 to move forward together until the wire harness terminal is molded by the first pusher 9 and the arc-shaped positioning member 8. The arc-shaped slide groove 1 of the plastic part is positioned. During this process, the length of the first telescopic member 10 remains unchanged. After the arc-shaped slide groove 1 is positioned, as the second telescopic member 12 continues to extend, the first rod 1002 and the second rod 1001 will overcome the elasticity of the limiting spring 1003 and move closer to each other, thereby driving the second pusher 11 to approach the plastic part of the wire harness terminal until it contacts the plastic shell 2 and drives the plastic shell 2 to move. When resetting, the first rod 1002 and the second rod 1001 are reset by the action of the limiting spring 1003.

[0045] In this embodiment, only the movement of the second telescopic member 12 needs to be controlled to control the movement of the first push member 9 and the second push member 11. The structure is simple, easy to use, and easy to maintain.

[0046] In this embodiment, the second pusher 11 includes an "L"-shaped plate 1101. The "L"-shaped structure facilitates connection with the electric telescopic rod of the second telescopic member 12. The "L"-shaped plate 1101 is provided with several push plates 1103 inclinedly arranged. When the second pusher 11 moves forward, it drives the push plates 1103 to move forward. When the push plates 1103 contact the rubber shell 2, they push the rubber shell 2 to move, causing the rubber shell 2 to move along the arc-shaped slide groove 1. The rubber shell 2 maintains balance under the action of the push plates 1103 and the elastic connecting ribs 3, thereby achieving the positioning of the rubber shell 2.

[0047] In this embodiment, the "L"-shaped plate 1101 is provided with a mounting component 1102. The push plate 1103 is detachably mounted on the "L"-shaped plate 1101 through the mounting component 1102, and the mounting position can be adjusted. Specifically, the mounting component 1102 may be provided with several slots, and the push plate 1103 is inserted into the mounting component 1102 through the slots. Through multiple slots, the number and position of the push plate 1103 can be flexibly adjusted, thus making it suitable for use with plastic parts of wire harness terminals of various specifications.
