Abstract
Description
Technical Field
[0001] This utility model relates to the field of wire harness design technology, and in particular to a flip-type wire harness structure. Background Technology
[0002] Wire harnesses are flexible media used to transmit electrical signals between devices. These signals are transmitted via wires and metal terminals, while connectors are used to mount the metal terminals and mate with the target object. With the development of industrial automation technology, although many products have entered the era of automated operation, wire harnesses are typical non-standard products. Different equipment (such as automobiles, home appliances, and industrial machinery) have vastly different requirements for wire harness specifications, lengths, and interface designs. Therefore, wire harness manufacturing remains primarily a manual operation.
[0003] In traditional wire harness manufacturing, after the metal terminals are crimped to the wires, the metal terminals need to be inserted axially from back to front into the connector. Multiple metal terminals need to be precisely installed in the connector according to a pre-defined array. Workers, however, can only rely on memory to insert the metal terminals into the corresponding slots, resulting in high workload. Since a large number of metal terminals need to be inserted into the same connector, under high-intensity working conditions, it is easy for the metal terminals to be inserted incorrectly, causing the wire harness to fail electrical tests and requiring rework.
[0004] Therefore, it is necessary to improve the traditional wire harness structure, reduce the manual labor intensity in the process of connecting metal terminals, and improve product yield. Utility Model Content
[0005] Based on this, the present invention provides a flip-top wire harness structure. By utilizing the flip-top connector structure, during the process of inserting metal terminals, operators can quickly find the correct terminal slot by visually distinguishing the markings after opening the cover, thereby reducing the manual labor intensity in the process of inserting metal terminals and improving product yield.
[0006] A flip-type wire harness structure includes:
[0007] A connector; the connector includes: a base and a cover hinged to the base; the front end of the base has multiple tubular terminal slots arranged in an array, and the rear end of the base has multiple limiting grooves that correspond one-to-one with the terminal slots and are linearly connected; the bottom of each limiting groove has a distinguishing mark; the cover is placed over the rear end of the base; the front end of the cover is hinged to the base, and the rear end of the cover has a latching part for engaging the rear end of the base; the bottom of the cover has multiple downwardly protruding anti-reverse pins; each limiting groove has at least one anti-reverse pin;
[0008] Multiple metal terminals are mounted on the connector; the front ends of each metal terminal are inserted into a terminal slot, and the rear ends of each metal terminal are received in a limiting groove and abut against a locking pin; each metal terminal has a laterally extending stop plate at its rear end; the front end of the stop plate abuts against the rear end of the terminal slot; and
[0009] The wires connecting the metal terminals; there are multiple wires, and each wire is connected to the rear end of the metal terminal in a one-to-one correspondence.
[0010] In the aforementioned flip-top wire harness structure, during assembly, the connector cover is flipped open to expose the base's retaining groove. Then, based on the distinguishing markings on the retaining groove, the pre-connected metal terminals are placed into the groove, and then pushed forward to insert into the terminal slot until the stop plate abuts against the base. After all metal terminals are inserted, the cover is flipped back to its original position, covering the rear end of the base until the latch engages with the rear end of the base. At this point, the anti-reverse pin at the bottom of the cover engages with the metal terminal to lock its axial position, preventing it from retracting. This flip-top connector structure allows operators to quickly locate the correct terminal slot by visually identifying the markings after opening the cover, reducing manual labor intensity and improving product yield.
[0011] In one embodiment, the distinguishing identifier is a number, letter, or symbol. Using numbers, letters, or symbols allows operators to quickly differentiate between different terminal slots, improving the accuracy of connection.
[0012] In one embodiment, the rear end of the metal terminal is provided with a socket for inserting the bottom end of a backstop pin. Axial positioning of the metal terminal is achieved by inserting the backstop pin into the socket, thus preventing it from retracting.
[0013] In one embodiment, the rear end of the stop plate abuts against the front end of the anti-reverse pin. The stop plate is clamped and fixed by the terminal slot and the anti-reverse pin, thereby preventing it from sliding backward.
[0014] In one embodiment, each metal terminal has two left-right mirror-symmetrical stop plates at its rear end. The symmetrically arranged stop plates can improve the force balance of the metal terminal when it is pulled.
[0015] In one embodiment, the connector further includes a limiting member disposed between the base and the cover; one end of the limiting member is provided with a pin portion; the pin portion is inserted laterally into the cover and the base. The limiting member can provide axial positioning for the base and the cover.
[0016] In one embodiment, the limiting member snaps onto the outside of the base. This snap-fit design facilitates the disassembly and assembly of the limiting member.
[0017] In one embodiment, the flip-type wiring harness structure further includes insulating tape wrapped around the outer periphery of the cover and the base. The insulating tape serves to waterproof and reinforce the surface, and is easy to install and remove. Attached Figure Description

[0044] Example 1
[0045] like Figures 1 to 9 As shown, it is a flip-type wire harness structure 100 of one embodiment of the present utility model.
[0046] like Figures 1 to 5 As shown, the flip-type wire harness structure 100 includes: a connector 10, a plurality of metal terminals 20 passing through the connector 10, and wires 30 connecting the metal terminals 20.
[0047] The following text, combined with Figures 1 to 9 The above-mentioned flip-type wire harness structure 100 will be further explained.
[0048] like Figure 6 As shown, connector 10 includes: a base 11 and a cover 12 hinged to the base 11. (The last sentence appears to be incomplete and possibly refers to a different product.) Figure 2 and Figure 7 As shown, the front end of the base 11 has multiple tubular terminal slots 111 arranged in an array, and the rear end of the base 11 has multiple limiting grooves 112 that correspond one-to-one with the terminal slots 111 and are linearly connected. Each limiting groove 112 has a distinguishing mark 1121 on its bottom. Combined with... Figure 1 and Figure 6 As shown, the cover 12 is fitted over the rear end of the base 11. The front end of the cover 12 is hinged to the base 11, and combined with... Figure 1 and Figure 8 As shown, the rear end of the cover 12 is provided with a latching portion 121 for engaging the rear end of the base 11. The bottom of the cover 12 is provided with multiple downwardly protruding anti-retraction pins 122. (See diagram below.) Figure 2 As shown, each limiting groove 112 has at least one anti-reverse pin 122.
[0049] Combination Figure 1 and Figure 6 As shown, in this embodiment, the connector 10 can be equipped with six metal terminals 20. Therefore, two covers 12 are hinged on the same base 11 and are opened and closed by flipping up and down.
[0050] like Figure 7 As shown, in this embodiment, the distinguishing identifier 1121 is a number. In other embodiments, the distinguishing identifier 1121 may also be a letter or a symbol. Using numbers, letters, or symbols allows operators to quickly distinguish different terminal slots 111, improving the accuracy of connection.
[0051] like Figure 2 and Figure 3 As shown, the front ends of the metal terminals 20 are inserted one-to-one into the terminal slots 111, as... Figure 5 As shown, the rear ends of the metal terminals 20 are respectively housed in the limiting grooves 112 and abut against the anti-reverse pins 122. Figure 9 As shown, each metal terminal 20 has a laterally extending stop 21 at its rear end. Figure 5 As shown, the front end of the stop plate 21 abuts against the rear end of the terminal slot 111.
[0052] In this scheme, there are multiple ways to connect the metal terminal 20 and the anti-reverse pin 122.
[0053] For example, such as Figure 2As shown, in this embodiment, the rear end of the stop plate 21 abuts against the front end of the anti-reverse pin 122. The stop plate 21 is clamped and fixed by the terminal slot 111 and the anti-reverse pin 122, thereby preventing it from moving backward.
[0054] Furthermore, such as Figure 9 As shown, in this embodiment, each metal terminal 20 has two stop plates 21 arranged in a left-right mirror symmetrical configuration at its rear end. The symmetrically arranged stop plates 21 can improve the force balance of the metal terminal 20 when it is pulled.
[0055] For example, in other embodiments, the rear end of the metal terminal 20 is provided with a socket for the bottom end of the anti-reverse pin 122 to be inserted. The anti-reverse pin 122 is inserted into the socket to achieve axial positioning of the metal terminal 20, thereby preventing it from retracting.
[0056] like Figure 2 and Figure 5 As shown, there are multiple wires 30, each connected to the rear end of the metal terminal 20 in a one-to-one correspondence.
[0057] Brief description of working principle:
[0058] like Figure 6 As shown, during assembly, the cover 12 of connector 10 is flipped open to expose the limiting groove 112 of base 11. Next, according to the distinguishing mark 1121 on the limiting groove 112, the metal terminal 20, pre-connected to the wire 30, is placed into the limiting groove 112, and then the metal terminal 20 is pushed forward to insert into the terminal slot 111 until the stop piece 21 abuts against base 11. Figure 1 and Figure 2 As shown, after all the metal terminals 20 have been inserted, the cover 12 is flipped back to its original position, so that the cover 12 covers the rear end of the base 11 until the latching part 121 engages with the rear end of the base 11. At this time, the anti-reverse pin 122 at the bottom of the cover 12 mates with the metal terminal 20 to lock the axial position of the metal terminal 20, so that the metal terminal 20 cannot retract.
[0059] The aforementioned flip-top wire harness structure 100 utilizes a flip-top connector 10 structure, allowing operators to quickly locate the accurate terminal slot 111 by visually distinguishing the markings 1121 after opening the cover 12 during the insertion of the metal terminal 20. This reduces the manual labor intensity in the process of inserting the metal terminal 20 and improves the product yield.
[0060] Example 2
[0061] like Figures 10 to 12 As shown, it is a flip-type wire harness structure 100 of one embodiment of the present utility model.
[0062] The difference between this embodiment and Embodiment 1 is that: Figure 10 and Figure 11 As shown, in this embodiment, the connector 10 further includes a limiting member 40 that passes between the base 11 and the cover 12. (Combined with...) Figure 11 and Figure 12 As shown, one end of the limiting member 40 is provided with a pin portion 41, which is inserted laterally into the cover 12 and the base 11. The limiting member 40 can axially limit the base 11 and the cover 12.
[0063] Furthermore, such as Figure 10 and Figure 11 As shown, the limiting member 40 is snapped onto the outside of the base 11 (see reference). Figure 7 A snap-fit notch 113 matching the limiting member 40 is provided on the outer side of the rear end of the base 11. The snap-fit method facilitates the disassembly and assembly of the limiting member 40.
[0064] The other structures in this embodiment are the same as in Embodiment 1, and it can also achieve the beneficial effects of Embodiment 1.
[0065] Example 3
[0066] like Figure 13 As shown, it is a flip-type wire harness structure 100 of one embodiment of the present utility model.
[0067] The difference between this embodiment and Embodiment 1 is that: Figure 13 As shown, in this embodiment, the flip-type wiring harness structure 100 further includes insulating tape 50 wrapped around the outer periphery of the cover 12 and the base 11. The insulating tape 50 serves to waterproof and reinforce, and is easy to install and remove.
[0068] The other structures in this embodiment are the same as in Embodiment 1, and it can also achieve the beneficial effects of Embodiment 1.
[0069] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0070] The above embodiments only illustrate preferred implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
