Description

Technical Field

[0001] This application relates to the field of wire harness technology, and in particular to a robust wire harness structure. Background Technology

[0002] A wire harness is a component formed by bundling multiple electrical connection wires required for connecting electronic devices into a bundle with an insulating sleeve. Terminals are usually installed at the ends by welding or crimping. The terminals are used to connect the wires to other electrical equipment to achieve electrical connection. The materials are usually brass, bronze, etc., and different plating treatments can be applied according to requirements.

[0003] In existing technologies, terminals are typically pressed onto wires in a double-C structure using a crimping process. However, during crimping, due to factors such as operator skill and the material itself, the double-C structure may suffer from insufficient curvature, asymmetrical C-shapes, or offset crimping center. This results in insufficient crimping force, making it easy for the terminals and wires to loosen. Consequently, the wires cannot be completely secured after crimping and are prone to popping out of the terminals, leading to poor crimping effect and low processing yield. Utility Model Content

[0004] This application provides a more stable and robust wire harness structure.

[0005] The robust wire harness structure provided in this application adopts the following technical solution:

[0006] A robust wire harness structure includes a conductor, a Y-shaped branch sleeve, a protective sleeve, and a terminal. The Y-shaped branch sleeve is connected to the protective sleeve. The conductor passes through the Y-shaped branch sleeve and the protective sleeve, forming a first branch and a second branch through the Y-shaped branch sleeve. The terminal includes a body with a connecting hole on one longitudinal side and a snap-fit ​​groove on the other side. The snap-fit ​​groove has a first latch and a second latch on both transverse sides, which snap into the snap-fit ​​groove and form a first mounting groove and a second mounting groove with the body, respectively. The first branch is fixed in the first mounting groove, and the second branch is fixed in the second mounting groove.

[0007] Preferably, the first buckle has a plurality of first strip grooves along its width direction, and the plurality of first strip grooves are distributed along the length direction of the first buckle; the second buckle has a plurality of second strip grooves along its width direction, and the plurality of first strip grooves are distributed along the length direction of the second buckle.

[0008] Preferably, the snap-fit ​​groove is a stepped groove, the upper width of the snap-fit ​​groove is smaller than the lower width, and the ends of the first buckle and the second buckle are fastened to the lower part of the snap-fit ​​groove.

[0009] Preferably, the main body is further provided with a stop block, which is connected to the side of the first buckle and the second buckle near the connection hole and covers the ends of the first mounting groove and the second mounting groove near the connection hole. The stop block is made of conductive material.

[0010] Preferably, a first insulating sleeve is provided between the Y-shaped branch sleeve and the first branch, and the first insulating sleeve abuts against the groove wall of the first mounting groove; a second insulating sleeve is provided between the Y-shaped branch sleeve and the second branch, and the second insulating sleeve abuts against the groove wall of the second mounting groove.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] 1. This application sets a Y-shaped branch sleeve to form a first branch and a second branch at the end of the wire. The first branch and the second branch are respectively set in the first mounting groove and the second mounting groove and separated by the main body. Compared with the prior art, the stable wire harness structure of this application has stronger fixation of the wire. The wire between the first clip and the second clip is not easy to pop out during crimping, which ensures the stability of the connection structure between the wire and the terminal, and thus ensures the conductivity after connection.

[0013] 2. By setting a stop, when the first branch and the second branch are respectively set in the first mounting groove and the second mounting groove, their ends abut against the stop along the longitudinal direction, which increases the contact area with the terminal, thereby increasing conductivity and reducing the risk of leakage due to end exposure.

[0014] 3. By setting the first insulating sleeve and the second insulating sleeve to fill the gap formed after the first branch and the second branch are installed into the first mounting groove and the second mounting groove respectively, leakage can be prevented when the first branch and the second branch are partially exposed during use, and the stability of the connection can also be enhanced.

[0021] The present application will be further described in detail below with reference to the accompanying drawings.

[0022] This application provides a robust wire harness structure, such as Figures 1 to 5 As shown, the device includes a wire 1, a Y-shaped branch sleeve 2, a protective sleeve 3, and a terminal 4. The Y-shaped branch sleeve 2 is connected to the protective sleeve 3. The wire 1 passes through the Y-shaped branch sleeve 2 and the protective sleeve 3, and forms a first branch 11 and a second branch 12 through the Y-shaped branch sleeve 2. The terminal 4 includes a body 41. A connection hole 411 is formed on one side of the body 41 along the longitudinal direction. The connection hole 411 is used to connect external equipment. A snap-fit ​​groove 42 is formed on the other side. A first snap-fit ​​43 and a second snap-fit ​​44 are respectively provided on both sides of the snap-fit ​​groove 42 along the transverse direction. The first snap-fit ​​43 and the second snap-fit ​​44 snap into the snap-fit ​​groove 42 and form a first mounting groove 45 and a second mounting groove 46 with the body 41, respectively. The first branch 11 is fixed in the first mounting groove 45, and the second branch 12 is fixed in the second mounting groove 46.

[0023] During installation, the first branch 11 and the second branch 12 are placed on both sides of the snap-fit ​​groove 42 along the lateral direction. Then, the first buckle 43 and the second buckle 44 are pressed together in a curled shape by a crimping process to form a double C structure. At the same time, the ends of the first buckle 43 and the second buckle 44 are pressed into the snap-fit ​​groove 42 to complete the installation.

[0024] In a robust wire harness structure of this application, the wire 1 is in a single bundle state within the protective sleeve 3. By setting a Y-shaped branch sleeve 2, the end section of the wire 1 forms a first branch 11 and a second branch 12. The first branch 11 and the second branch 12 are respectively set in the first mounting groove 45 and the second mounting groove 46, and are separated by the main body 41. When the first buckle 43 and the second buckle 44 form a C-shaped structure, they can be symmetrical about the snap-fit ​​groove 42 as the center, which ensures the crimping yield and makes it difficult for the center of the first buckle 43 and the second buckle 44 to shift, thereby ensuring the crimping force. Compared with the prior art, the robust wire harness structure of this application has stronger fixation for the wire 1. The wire 1 between the first buckle 43 and the second buckle 44 is not easy to pop out during crimping, which ensures the stability of the connection structure between the wire 1 and the terminal 4, thereby ensuring the conductivity after connection.

[0025] like Figure 3 As shown, the first buckle 43 has multiple first strip grooves 431 along its width direction, and the multiple first strip grooves 431 are distributed along the length direction of the first buckle 43. The second buckle 44 has multiple second strip grooves 441 along its width direction, and the multiple first strip grooves 431 are distributed along the length direction of the second buckle 44. Specifically, the width direction of the first buckle 43 and the second buckle 44 is the longitudinal direction in the figure, the length direction of the first buckle 43 is the circumferential direction of the first mounting groove 45, and the length direction of the second buckle 44 is the circumferential direction of the second mounting groove 46.

[0026] The first branch 11 and the second branch 12 of the conductor 1 include multiple non-adhesive wires. After the first branch 11 and the second branch 12 are respectively crimped into the first mounting groove 45 and the second mounting groove 46, the wires of the first branch 11 are arranged parallel to the first strip groove 431. Multiple wires are embedded into the first strip groove 431 by crimping. By setting the first strip groove 431, the contact area between the first mounting groove 45 and the first branch 11 is increased. At the same time, the first strip groove 431 reinforces the connection structure between the first branch 11 and the first mounting groove 45 by fitting with some wires, further ensuring the stability of the connection. The cooperation effect of the second branch 12, the second strip groove 441 and the second mounting groove 46 is similar to the above.

[0027] like Figure 3 As shown, the snap-fit ​​groove 42 is a stepped groove, with the upper width of the snap-fit ​​groove 42 being smaller than the lower width. The ends of the first snap-fit ​​43 and the second snap-fit ​​44 are snapped into the lower part of the snap-fit ​​groove 42. Specifically, the ends of the first snap-fit ​​43 and the second snap-fit ​​44 are rolled and embedded into the snap-fit ​​groove 42 through a pressing process, and are snapped into the lower part of the snap-fit ​​groove 42. Since the upper width of the snap-fit ​​groove 42 is smaller than the lower width, the ends of the first snap-fit ​​43 and the second snap-fit ​​44 can be snapped into the upper part of the lower part, that is, the bottom of the upper part, making the connection structure between the first snap-fit ​​43 and the second snap-fit ​​44 and the main body 41 more stable after pressing.

[0028] like Figure 4 As shown, the main body 41 is also provided with a stop block 47. The stop block 47 is connected to the side of the first buckle 43 and the second buckle 44 near the connecting hole 411, and covers the ends of the first mounting groove 45 and the second mounting groove 46 near the connecting hole 411. The stop block 47 is made of conductive material. Specifically, the stop block 47 is integrally cast with the main body 41 and is made of conductive material. The stop block 47 is independent of the first buckle 43 and the second buckle 44. When the first buckle 43 and the second buckle 44 are bent by the pressing process, the stop block 47 is not affected, and covers the ends of the first mounting groove 45 and the second mounting groove 46 near the connecting hole 411 after the first mounting groove 45 and the second mounting groove 46 are formed.

[0029] Thus, when the first branch 11 and the second branch 12 are respectively disposed in the first mounting groove 45 and the second mounting groove 46, their ends abut against the stop block 47 in the longitudinal direction, which increases the contact area with the terminal 4, thereby increasing conductivity and reducing the risk of leakage due to end exposure.

[0030] like Figure 1 and 2 As shown, a first insulating sleeve 5 is provided between the Y-shaped branch sleeve 2 and the first branch 11, and the first insulating sleeve 5 abuts against the groove wall of the first mounting groove 45. A second insulating sleeve 6 is provided between the Y-shaped branch sleeve 2 and the second branch 12, and the second insulating sleeve 6 abuts against the groove wall of the second mounting groove 46. Specifically, the Y-shaped branch sleeve 2 has a diameter difference with the first branch 11 and the second branch 12. After the first branch 11 and the second branch 12 are respectively connected in the first mounting groove 45 and the second mounting groove 46, a gap will be formed between the connection between the first branch 11 and the Y-shaped branch sleeve 2 and the first mounting groove 45. The gap is filled by providing the first insulating sleeve 5 to prevent leakage due to the first branch 11 being partially exposed during use, and also to enhance the stability of the connection. The second insulating sleeve 6 applied in the second mounting groove 46 has a similar effect.

[0031] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
