[0002] Existing electrical connectors generally consist of an insulating base, conductive plates, and fastening screws.

[0003] The existing electrical connector terminals are fixed and limited by only the locking screws and the barbs on both sides of the terminal connection, which is insufficient for electrical connectors that require stable connection performance. Summary of the Invention

[0004] The purpose of this invention is to design an electrical connector that further improves the connection stability of the connection terminals. Moreover, the structure is simple, reducing the difficulty and cost of manufacturing parts.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] Insulating base, including,

[0008] A base plate with several longitudinal partitions arranged in parallel at intervals, forming several independent compartments along the length of the base plate, with an installation platform on the base plate inside each compartment;

[0009] A transverse partition is inserted into the middle of the longitudinal partition, dividing the compartment into several corresponding power supply side chambers and load side chambers along the width of the bottom plate. A gap is maintained between the bottom surface of the transverse partition and the mounting platform to form a channel for the wiring terminals to pass through. The mounting platform in the power supply side chamber is provided with blind holes for the wiring locking screws to pass through, and a fixing groove for placing nuts is provided above the blind holes.

[0010] A transverse top plate is connected parallel to the top surface of the transverse partition on one side; a reinforcing rib is provided between the center of the transverse partition and the bottom surface of the transverse top plate in the load-side cavity; the load-side cavity is also provided with an independent vertically penetrating receiving groove and a fixing column therein, the receiving groove is located between two adjacent reinforcing ribs, and the two side walls of the receiving groove are symmetrically provided with limiting holes, and correspondingly, the outer wall of the fixing column is provided with a limiting block that cooperates with the limiting hole;

[0011] Several terminals, one end of which is a conductive sheet with a connecting through hole, and the other end is provided with a connecting part for connecting the load side wire; the conductive sheet is disposed on the mounting platform in the power supply side cavity, and one rear end of the conductive sheet is bent downward to form a limiting part; correspondingly, one side of the upper surface of the mounting platform is provided with a limiting groove for the limiting part to abut against the required limiting groove.

[0012] Several wiring locking screws and nuts are provided. The nuts are respectively set in the mounting platform fixing groove in the power supply side cavity. The wiring locking screws pass through the conductive plate connection hole of the wiring terminal and the nuts are in the blind hole of the mounting platform.

[0013] Preferably, a stop for the wiring terminal is protruding from the outer end of the mounting platform inside the power supply side cavity.

[0014] Preferably, the conductive sheet of the terminal block is bent upward on both sides at the rear end to form a limiting stop, which cooperates with the bottom end of the transverse partition to form a limiting structure.

[0015] Preferably, the base plate of the insulating base, the mounting platform on the base plate, the longitudinal partition, the transverse partition, the transverse top plate and the reinforcing rib are designed as an integral unit.

[0016] The beneficial effects of this utility model are:

[0017] The present invention has a limiting part designed on the conductive sheet of the terminal block, which, together with the limiting groove of the mounting platform on the insulating base, can prevent the terminal block from being installed backwards and further improve the assembly stability of the terminal block in the insulating base.

[0018] This invention incorporates reinforcing ribs in the insulating base, increasing the resistance to pulling out the terminals and preventing them from being pulled out arbitrarily; a certain amount of pulling force is required to pull out the terminals.

[0019] The fixed column of this invention has a protruding limiting block on its outer wall, which, together with the limiting hole on the side wall of the receiving groove in the insulating base, can prevent the fixed column from falling off.

[0020] In addition, a stop is designed on the insulating base to accommodate the insertion of the terminal head, which can press down on the terminal head to prevent it from bending or tilting, thus affecting the pulling and use of the terminal head and improving the assembly stability of the terminal head in the insulating base.
