[0033] like Figures 1 to 4 As shown, this utility model embodiment provides a connector, which includes a plug plate, a bracket, and an inner covering layer 3. The plug plate includes a plug plate body 11 and a plurality of sealing heads 12 connected to one end of the plug plate body 11. When the plug plate body 11 abuts against the bracket 2, the plurality of sealing heads 12 are correspondingly embedded in a plurality of mounting slots 24 of the bracket 2. The inner covering layer 3 covers one side of the bracket 2 where the mounting slots 24 are located. The bracket 2 has a mounting surface 21. At least two sealing heads 12 are arranged sequentially along a first direction, and the embedding direction of the sealing heads 12 and the mounting slots 24 is a second direction. The mounting surface 21 is parallel to the plane formed by the first and second directions. One side of the plug plate body 11 is configured to abut against the mounting surface 21 of the bracket 2, and a retaining platform is provided on the other side to isolate the mounting slots 24 from the inner covering layer 3.

[0034] In this embodiment, when one side of the plug plate body 11 abuts against the mounting surface of the bracket, the multiple sealing heads 12 of the plug plate are embedded in the multiple mounting slots 24 of the bracket in a one-to-one correspondence, thereby realizing the assembly between the plug plate and the bracket 2; the inner covering layer 3 covers the side of the bracket 2 where the mounting slot 24 is located. Since a baffle is provided on the other side of the plug plate body 11 opposite to the mounting surface 21, the baffle is used to isolate the mounting slot 24 and the inner covering layer 3. Therefore, when the inner covering layer 3 is injection molded, the baffle can block the molten inner covering layer 3 outside the gap between the mounting slot 24 and the sealing head 12, so as to prevent the inner covering layer 3 from flowing into the mounting slot 24 during the injection molding process and forming flash, thereby improving the manufacturing yield of the product; specifically, the bracket 2 is provided with a port and a connection port at both ends along the second direction. The connection port is used to connect the wire harness 4, and the port is used to connect to electronic equipment.

[0035] like Figure 1 and Figure 2As shown, the highest point of the surface of the inner covering layer 3 pointing from the mounting surface 21 to the side of the enclosure platform is lower than the lowest point of the surface of the enclosure platform facing away from the mounting surface. Therefore, when the inner covering layer 3 is injection molded, the enclosure platform can prevent the molten inner covering layer 3 from flowing from the top of the enclosure platform into the gap between the mounting groove 24 and the sealing head 12. In this embodiment, the surface of the enclosure platform facing away from the mounting surface 21 is the mounting surface 13, that is, the opposite side surface of the enclosure platform and the plug plate body 11 is the mounting surface 13. In a specific embodiment, three mounting grooves 24 are provided on one side of the bracket 2, and three sealing heads 12 are correspondingly provided on the plug plate. When all the sealing heads 12 are embedded in the mounting grooves 24, three grooves are formed between each sealing head 12 and the mounting groove 24. The joints consist of a top joint extending along the first direction and two opposing vertical joints, forming a total of nine joints between the three sealing heads 12 and the three assembly slots 24. Since the highest point of the surface of the inner covering layer 3 pointing from the assembly surface 21 to the side of the enclosure is lower than the lowest point of the mounting surface 13, the inner covering layer 3 can only partially contact the outermost two vertical joints of the nine joints. That is, the enclosure blocks the inner covering layer 3 from other joints, thereby greatly reducing the amount of adhesive material of the inner covering layer 3 entering the vertical joints. This also reduces the amount of the backpack covering layer 3 entering the top joint due to extrusion, thus greatly reducing the occurrence of flash during the injection molding process. Specifically, the vertical direction is the direction perpendicular to the assembly surface 21.

[0036] Specifically, the surface on the enclosure platform facing away from the assembly surface 21 is a plane, and the distance between the plane and the assembly surface 21 is H1; the surface on the inner covering layer 3 pointing from the assembly surface 21 to the enclosure platform is also a plane, and the distance between the plane and the assembly surface 21 is H2, and H1 is greater than H2.

[0037] The enclosure platform can be a surrounding structure located around or on the outer perimeter of the other side of the plug plate body 11, or it can be a closed structure formed by the entire plug plate body 11 extending vertically. In this embodiment, to reduce the weight and production cost of the connector, the enclosure platform is U-shaped; specifically, the surface of the plug plate body 11 facing away from the assembly surface 21 is rectangular, and the enclosure platform is a U-shaped enclosure structure formed by three continuous parts along the edge of this surface, with each of the three parts contacting the inner covering layer 3; the enclosure platform can also be a U-shaped enclosure structure formed by four continuous parts along the edge of the surface of the plug plate body 11 facing away from the assembly surface 21. In another embodiment, to improve the structural strength of the plug plate itself and avoid the expansion of the gap between the sealing head 12 and the assembly groove 24 due to deformation of the plug plate during the injection molding of the inner covering layer 3, thus exacerbating the generation of flash, such as... Figure 2 and Figure 4As shown, the enclosure platform is formed by extending the plug plate body 11 to a certain depth along the direction of the assembly surface 21 pointing towards the enclosure platform; specifically, the surface of the plug plate body 11 facing away from the assembly surface 21 is rectangular, and this surface extends along the direction of the assembly surface 21 pointing towards the enclosure platform to form the enclosure platform, that is, the enclosure platform is a cuboid structure.

[0038] The barrier platform, the plug plate body 11, and the sealing head 12 are integrally formed, thereby improving the structural strength of the plug plate and preventing the plug plate from deforming during the injection molding of the inner covering layer 3, which would cause the joint between the sealing head 12 and the assembly groove 24 to become larger.

[0039] Furthermore, such as Figure 2 and Figure 4 As shown, there are two plug plates, which are symmetrically arranged on the bracket 2. Specifically, the connector is a symmetrical structure with respect to the first direction and the second direction. Two sets of assembly slots are symmetrically arranged on the bracket 2. Each assembly slot includes three assembly slots 24 arranged sequentially along the first direction. Correspondingly, there are two plug plates on the connector, which are symmetrically arranged on the bracket 2. The sealing head 12 on each plug plate is embedded in the assembly slot on the same side.

[0040] To facilitate the assembly of the plug plate and bracket 2, such as Figures 2 to 5 As shown, a sliding block 14 is provided on the plug plate body 11. The sliding block 14 and the blocking platform are located on opposite sides of the plug plate body 11. The bracket 2 is provided with a guide groove 23 that matches the sliding block 14. The surface of the guide groove 23 near the sliding block 14 is the assembly surface 21. The sliding direction of the sliding block 14 along the guide groove 23 is parallel to the second direction. Specifically, the guide groove 23 is formed by the side wall surface and the bottom surface of the groove. The bottom surface of the groove is parallel to the plane formed by the first direction and the second direction. The sliding block 14 has a mating bottom surface that rubs against the bottom surface of the groove and a mating side surface that rubs against the side wall surface. In this embodiment, the bottom surface of the groove is the assembly surface 21 of the bracket 2. By aligning the sliding block 14 with the guide groove 23 and pushing the plug plate to slide along the second direction on the assembly surface 21, the sliding engagement between the sliding block 14 and the guide groove 23 can be achieved, thereby finally realizing the embedding of the sealing head 12 and the assembly groove 24.

[0041] like Figure 2 and Figure 4As shown, limiting portions are provided on both sides of the guide slide 23 in the direction perpendicular to the assembly surface 21 and pointing towards the enclosure platform. The limiting portions can limit the sliding block 13 in the direction perpendicular to the assembly surface 21 to prevent the sliding block 13 from vertically dislodging from the guide slide 23, thereby improving the structural stability and reliability of the connector. The specific structure of the limiting portions can be set according to the actual situation. For example, in the direction perpendicular to the assembly surface 21 and pointing towards the enclosure platform, the distance between the two side walls of the guide slide 23 gradually decreases, that is, the limiting portions are formed by the extension structure of the two side walls of the guide slide 23.

[0042] To reduce the assembly difficulty between bracket 2 and the plug plate, such as Figure 2 and Figure 5 As shown, the width of the guide groove 23 gradually increases along the opposite direction of the sealing head 12 and the assembly groove 24. Therefore, when inserting the sliding block 13 into the guide groove 23, there is no need to work hard to align the sliding block 13 with the guide groove 23 along the second insertion direction, which saves time and effort and is easy to assemble.

[0043] like Figure 4 and Figure 5 As shown, multiple sliding blocks 14 and guide grooves 23 are respectively provided one-to-one. Multiple sliding blocks and multiple guide grooves 23 slide in a one-to-one manner, which further improves the reliability and stability of the connection between the plug plate and the bracket 2.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
