Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a socket for a wire harness connector. Background Technology

[0002] Wire harness connectors are a type of terminal, also known as plugs, consisting of a plug and a socket. In the automotive industry, wire harness connectors serve as relay stations for wire harnesses in automotive circuits. With the increasing popularity of new energy vehicles and intelligent vehicles, the functional requirements for these vehicles are also growing, making the electrical systems of the entire vehicle increasingly complex. Among these components, wire harness connectors, as key components, directly affect the stability of the entire vehicle's electrical system.

[0003] Existing wire harness connector sockets consist of contacts and a plastic shell. The plastic shell has a split structure. After the contacts are installed, sealant needs to be filled inside the shell to fill the internal parts and limit their movement. However, since wire harness connectors are used in high-temperature environments, the sealant inside the shell will age under high temperatures, causing the sealant to deform. This can lead to movement of internal parts and even short circuits. Utility Model Content

[0035] like Figure 1-8 As shown, the present invention provides a socket for a wire harness connector, comprising:

[0036] The housing 1 is integrally formed and a front cover 2 is provided at one end of the housing 1. The housing 1 is injection molded using a high-temperature resistant material in the prior art. Compared with the split structure in the prior art, the integrally formed structure improves the sealing performance. At the same time, the housing 1 is provided with several installation channels. The housing 1 is provided with a snap-fit ​​groove 102, and the inlet and outlet positions of the snap-fit ​​groove 102 are provided with limit protrusions 103. The front cover 2 is provided with an elastic snap-fit ​​arm 201, and the other end of the elastic snap-fit ​​arm 201 is provided with a snap-fit ​​protrusion 202.

[0037] In the connected state, the front cover 2 is inserted into the housing 1, and the elastic snap-fit ​​arm 201 enters the snap-fit ​​groove 102 through the inlet and outlet. The limiting protrusion 103 snaps into the snap-fit ​​protrusion 202. In actual connection, the front cover 2 is inserted into the housing 11, and the elastic snap-fit ​​arm 201 is placed at the inlet and outlet position. When the front cover 2 is pushed into the housing 11, due to the presence of the limiting protrusion 103, the snap-fit ​​protrusion 202 on the elastic snap-fit ​​arm 201 moves relative to each other through the limiting protrusion 103, and causes the elastic snap-fit ​​arm 201 to deform. After the front cover 2 is continuously pushed, the snap-fit ​​protrusion 202 enters the other side of the limiting protrusion 103. Due to the elasticity of the elastic snap-fit ​​arm 201 itself, the snap-fit ​​protrusion 202 will snap into the limiting protrusion 103, thereby completing the fixation of the front cover 2 and the housing 11.

[0038] Several terminal groups 3 are inserted into several mounting channels and connected to wires 4; and several terminal groups 3 are respectively snapped into several mounting channels; specifically, after the wires 4 are pressed onto several terminal groups 3, several terminal groups 3 are inserted into several mounting channels. When several terminal groups 3 enter several mounting channels, several mounting channels will snap the several terminal groups 3 to ensure the stability of the installation of several terminal groups 3 in several mounting channels.

[0039] The technical solution of this utility model connects several terminal groups 3 by setting several mounting channels inside the housing 1, and during connection, the mounting channels engage with the terminal groups 3, ensuring the stability of the terminal groups 3 after installation. In addition, a snap-fit ​​groove 102 is provided on the housing 1, and a limiting protrusion 103 is provided at the inlet and outlet of the snap-fit ​​groove 102. When the front cover 2 is connected to the housing 1, the snap-fit ​​protrusion 202 on the elastic snap-fit ​​arm 201 engages with the limiting protrusion 103 to realize the connection between the front cover 2 and the housing 1, thereby improving the efficiency of disassembly and assembly between the front cover 2 and the housing 1. At the same time, since the housing 1 is integrally formed and several mounting channels are set inside the housing 1 for the installation of several terminal groups 3, compared with the prior art, there is no need to use sealant inside the housing 1, and it will not be affected by use in high temperature environment, ensuring that the internal components will not move.

[0040] like Figure 3-5 As shown, the housing 1 includes an outer shell 11 and a mounting cavity disposed in one end of the outer shell 11, with a plurality of mounting channels disposed in the mounting cavity; a limiting cavity 12 is disposed at the other end of the outer shell 11, and the front cover 2 passes through the limiting cavity 12; when connecting a plurality of terminal groups 3, the plurality of terminal groups 3 are inserted into a plurality of mounting channels and moved until the plurality of mounting channels are engaged with the plurality of terminal groups 3; when installing the front cover 2, the front cover 2 is inserted into the limiting cavity 12, and after the front cover 2 is pushed to move within the limiting cavity 12, the elastic snap-fit ​​arm 201 engages with the snap-fit ​​groove 102;

[0041] like Figure 6 and 7As shown, a limiting plate 13 is provided inside the limiting cavity 12, and a limiting groove 21 is provided on the front cover 2; in the connected state, the limiting plate 13 is inserted into the limiting groove 21; specifically, after the front cover 2 is inserted into the limiting cavity 12, the limiting plate 13 is placed in the limiting groove 21, and the position of the front cover 2 in the limiting cavity 12 is controlled under the restriction of the limiting plate 13; on the one hand, the movement of the front cover 2 in the limiting cavity 12 is stable; on the other hand, after the front cover 2 is fixed to the housing 1, the movement of the front cover 2 is prevented by the cooperation of the limiting plate 13 and the snap-fit ​​groove 102.

[0042] In addition, in this utility model, the mounting channel includes a first chamber 111 and a second chamber 112, which are disposed opposite to each other within the outer casing 11, with the first chamber 111 positioned above the second chamber 112; the plurality of terminal groups 3 include a first terminal bar 31 and a second terminal bar 32, the first terminal bar 31 passing through the first chamber 111 and the second terminal bar 32 passing through the second chamber 112. In this utility model, the outer surfaces of the first terminal bar 31 and the second terminal bar 32 are electroplated to improve their corrosion resistance and conductivity; a plurality of anti-retraction arms 113 are provided in both the first chamber 111 and the second chamber 112; in the connected state, the plurality of anti-retraction arms 113 are respectively engaged with the first terminal bar 31 and the second terminal bar 32; such as Figure 3 As shown, when the first terminal block 31 and the second terminal block 32 are placed in the first chamber 111 and the second chamber 112, the first terminal block 31 and the second terminal block 32 are respectively blocked by the anti-retraction arms 113 in the first chamber 111 and the second chamber 112, and cannot be retracted. Thus, the anti-retraction arms 113 restrict the first terminal block 31 and the second terminal block 32 within the first chamber 111 and the second chamber 112. It should be noted that in this utility model, the number of the first terminal block 31, the second terminal block 32, the first chamber 111, the second chamber 112 and the anti-retraction arms 113 are set as needed, and this utility model is not further limited.

[0043] To facilitate the insertion of the front cover 2 into the housing 1, this invention preferably includes a pressing plate 14 on the housing 1, with a snap-fit ​​groove 102 on the pressing plate 14. Pressing one end of the pressing plate 14 as needed activates the snap-fit ​​groove 102, thereby separating the elastic snap-fit ​​arm 201 from the snap-fit ​​groove 102. The front cover 2 is then disassembled after the elastic snap-fit ​​arm 201 and the snap-fit ​​groove 102 have separated. Furthermore, the elastic snap-fit ​​arm 201 includes a first arm 211 and a second arm 212, connected by a connecting plate 213 on the front cover 2. Snap-fit ​​protrusions 202 are respectively provided on the first arm 211 and the second arm 212. During the elastic snap-fit ​​process... When the connecting arm 201 and the locking groove 102 are installed, when the locking protrusion 202 and the limiting protrusion 103 come into contact, under the action of the limiting protrusion 103, the locking protrusion 202 drives the first arm body 211 and the second arm body 212 to move closer to each other; when the locking protrusion 202 enters the limiting protrusion 103, the first arm body 211 and the second arm body 212 are reset and the locking between the limiting protrusion 103 and the locking protrusion 202 is completed; when the front cover 2 is removed, one end of the pressing plate 14 is pressed, and through the lever principle, the limiting protrusion 103 on the other end of the pressing plate 14 moves upward and gradually disengages from the locking protrusion 202 during the movement; when the locking protrusion 202 is completely disengaged from the limiting protrusion 103, the front cover 2 can be removed.

[0044] Of course, in order to better connect the elastic snap-fit ​​arm 201 and the snap-fit ​​groove 102, in this utility model, preferably, one end of the first arm body 211 and the second arm body 212 is provided with a first guide surface 104; the snap-fit ​​protrusion 202 is provided with a second guide surface 203; in this way, when the front cover 2 and the housing 1 are installed, when the limiting protrusion 103 contacts the snap-fit ​​protrusion 202, the first guide surface 104 and the second guide surface 203 contact each other. Since the first guide surface 104 and the second guide surface 203 are both arc-shaped structures, the snap-fit ​​protrusion 202 can better enter the limiting protrusion 103, thereby improving the installation efficiency of the front cover 2 and the housing 1.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
