AI Technical Summary
The existing connection method between the terminal block and the socket is not designed properly, resulting in an excessively large socket size, which increases cost and assembly difficulty.
It adopts a miniaturized terminal block structure, which is assembled by abutting the front side of the mounting position with the left and right side plates and snapping the rear side of the mounting position with the elastic snap-fit part. The combination of guide ramp and elastic snap-fit achieves a stable connection between the terminal block and the terminal block.
It effectively reduces the size of terminals and sockets, simplifies the assembly process, reduces costs, and improves assembly efficiency.

Abstract
Description
Technical Field
[0001] This utility model relates to a connection structure between a terminal block and a connector. Background Technology
[0002] Air fryers and ovens typically feature work lights, which are mounted on junction boxes. Specifically, these junction boxes have terminals for connecting and transmitting electricity to the work lights. When a work light fails, the user can simply unplug it for replacement. However, current designs for the connection between junction boxes and junction boxes are not ideal. The junction boxes are generally large and tall, forcing the junction boxes to also become larger and thicker to accommodate them. This results in higher manufacturing costs and larger junction box sizes that hinder assembly.
[0003] Therefore, it is necessary to further improve it. Utility Model Content
[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a connection structure for terminals and sockets, which uses terminals and sockets that are relatively small in size.
[0005] To achieve the above objectives, we provide a connection structure for a terminal block and a terminal block, which includes a terminal block and a terminal block. The terminal block includes a back plate, a left side plate, and a right side plate. The left side plate and the right side plate are respectively disposed on the left and right sides of the back plate. The back plate is provided with a rearwardly protruding elastic snap-fit part. The terminal block has a mounting position for connecting the terminal block. The rear side of the mounting position is provided with a recess that engages with the elastic snap-fit part. The front ends of the left side plate and the right side plate can abut against the front side of the mounting position.
[0006] In one or more embodiments, the bottom end of the back plate is provided with a clamping portion for clamping wires.
[0007] In one or more embodiments, the back plate has an open "U"-shaped through groove, which cuts the back plate into a plate body, and the plate body is bent backward to form the elastic snap-fit part.
[0008] In one or more embodiments, a front plate is provided on the front side of the back plate, and the upper end of the back plate is connected to the upper end of the front plate through a connecting part.
[0009] In one or more embodiments, the connecting portion is an arched connecting portion, and the arched connecting portion is elastic.
[0010] In one or more embodiments, the insertion end of the mounting position is provided with a guide ramp, which is used to guide the elastic snap-fit portion into the recess.
[0011] Compared with the prior art, this utility model has the following technical effects: by improving the specific structure of the terminal block, the terminal block abuts against the front side of the mounting position through the left and right side plates, and the elastic snap-fit part snaps against the rear side of the mounting position. The terminal block is installed on the terminal block by snap-fit, which not only facilitates the assembly of the terminal block and the terminal block, but also effectively reduces the size of the terminal block, so that the size of the terminal block assembled with it is also reduced accordingly, making it convenient for the terminal block to be assembled and used on electrical appliances.

[0016] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.
[0017] Please refer to Figure 1-4 This application provides a connection structure for a terminal block and a terminal block, comprising a terminal block 1 and a terminal block 2. The terminal block 2 includes a back plate 3, a left side plate 4, and a right side plate 5, which are respectively disposed on the left and right sides of the back plate 3. The back plate 3 has a rearwardly protruding elastic locking part 6. The terminal block 1 has a mounting position 7 for connecting the terminal block. The rear side of the mounting position has a recess 8 that engages with the elastic locking part 6. The front ends of the left side plate 4 and the right side plate 5 can abut against the front side of the mounting position 7. Specifically, the terminal block is connected to the mounting position to be assembled on the terminal block. During the assembly of the terminal block, the elastic locking part is squeezed by the rear side of the mounting position, causing the elastic locking part to elastically deform towards the back plate. After the terminal block is fully inserted into the mounting position, the elastic locking part loses the pressure from the rear side of the mounting position and quickly rebounds backward, thus locking into the recess. At this time, under the locking action of the elastic locking part and the abutment action of the left and right side plates against the front side of the mounting position, the terminal block and the terminal block are assembled in place.
[0018] The bottom end of the back plate 3 is provided with a clamping part 9, which is used to clamp the wire 10. Specifically, the clamping part clamps the wire by bending and riveting.
[0019] The back plate 3 has an open "U"-shaped through groove. The "U"-shaped through groove cuts the back plate 3 into a plate. The plate is bent backward to form the elastic snap-fit part 6. The elastic snap-fit part is formed by opening a "U"-shaped through groove on the back plate and then bending the plate backward.
[0020] The back plate 3 has a front plate 11 on its front side. The upper end of the back plate is connected to the upper end of the front plate through a connecting part 12. The connecting part is preferably an arched connecting part. The arched connecting part is elastic and can make the front plate elastically compressed relative to the back plate. The front plate is used to make contact with the end foot of the work lamp for electrical conductivity.
[0021] The mounting position 7 has a guide ramp 13 at the insertion end. The guide ramp is used to guide the elastic snap-fit part 6 into the recess 8. As the terminal is gradually inserted into the mounting position, the elastic snap-fit part is gradually squeezed by the guide ramp and undergoes elastic deformation towards the back plate.
[0022] The above description is only a preferred embodiment of the present utility model. The protection scope of the present utility model is not limited to the above embodiments. Any equivalent modifications or changes made by those skilled in the art based on the content disclosed in the present utility model should be included in the protection scope recorded in the claims.
