For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0025] like Figure 1 and Figure 2 As shown, the wiring harness terminal provided by the embodiment of the present invention includes: a base 100, a snap-on portion 200 and a wiring sleeve 300; the snap-on portion 200 and the wiring sleeve 300 are respectively connected to the base 100; the snap-on portion 200 is adapted to the PCB mainboard 400, and the wiring sleeve 300 is used to connect the wiring harness.

[0026] The buckle portion 200 can be snapped into the slot on the PCB main board 400, thereby achieving the initial positioning and installation of the wiring harness terminal relative to the PCB main board 400. During the soldering process, soldering reinforcement can be performed at the location of the buckle portion 200 to improve the stability of the connection between the buckle portion 200 and the PCB main board 400.

[0027] In the embodiment of the present invention, a plurality of snap-fit ​​portions 200 are provided, and the plurality of snap-fit ​​portions 200 are spaced apart along the PCB main board 400. The PCB main board 400 is respectively engaged by the plurality of snap-fit ​​portions 200, and the plurality of snap-fit ​​portions 200 are jointly supported between the base 100 and the PCB main board 400, thereby ensuring that the base 100 and the PCB main board 400 are nearly parallel.

[0028] In an optional embodiment, at least one of the snap-fit ​​portions 200 is expanded and tightened in one of the slots along a first direction parallel to the PCB main board 400, and at least one of the snap-fit ​​portions 200 is expanded and tightened in another slot along a second direction parallel to the PCB main board 400. The first direction and the second direction have an angle, so that the wiring harness terminal can maintain a stable position relative to the PCB main board 400 in the direction in which the board extends.

[0029] Furthermore, the snap-fit ​​portion 200 includes: a first bevel portion 210 and a second bevel portion 220 ; the first bevel portion 210 and the second bevel portion 220 are both configured as a hollow structure, and the first bevel portion 210 and the second bevel portion 220 form a tip portion 201 for inserting the PCB mainboard 400 .

[0030] The hollow design allows the first angled portion 210 and the second angled portion 220 to be easily compressed and deformed, allowing the snap portion 200 to be smoothly inserted and engaged with the slot of the PCB mainboard 400. In addition, during soldering, solder can fill the hollow structure, preventing the snap portion 200 from being compressed and deformed, thereby achieving a reinforced connection.

[0031] In an optional embodiment, there is a clearance groove 202 between the first beveled portion 210 and the second beveled portion 220. During the process of inserting the tip 201 into the slot, the first beveled portion 210 and the second beveled portion 220 are squeezed, and the clearance groove 202 is squeezed and contracted until the buckle portion 200 is snapped into place, and the first beveled portion 210 and the second beveled portion 220 rebound and cause the clearance groove 202 to expand again.

[0032] Furthermore, the first beveled portion 210 is provided with a first wedge tail section 211, and the second beveled portion 220 is provided with a second wedge tail section 221; from the end close to the tip 201 to the end away from the tip 201, the distance between the first wedge tail section 211 and the second wedge tail section 221 decreases.

[0033] When the buckle portion 200 is buckled and installed in place, the first wedge tail section 211 and the second wedge tail section 221 abut against the inner wall of the slot to prevent the buckle portion 200 from loosening from the slot.

[0034] Furthermore, a side wall of the wiring sleeve 300 is provided with a notch groove 301 extending in the axial direction. By radially pressing the wiring sleeve 300, the notch groove 301 can be narrowed, thereby clamping the wiring harness in the wiring sleeve 300.

[0035] In an alternative embodiment, the axis of the wiring sleeve 300 is perpendicular to the plate surface of the base 100. In an alternative embodiment, the axis of the wiring sleeve 300 can also be parallel to or at an acute angle to the plate surface of the base 100, and the angle can be adaptively adjusted according to the installation space of the wiring harness terminal.

[0036] In this embodiment, the base 100 , the buckling portion 200 and the wiring sleeve 300 are configured as an integrated structure, which can reduce the number of parts, thereby reducing production costs and improving assembly efficiency.

[0037] The electrical equipment provided by the embodiment of the present invention is equipped with the wiring harness terminal described in the above embodiment. The electrical equipment has the technical advantages of low cost and high assembly efficiency of the above wiring harness terminal, which will not be described in detail here.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
