[0005] To achieve the above purpose, the utility model provides the following technical scheme: a split leg wire connector for digital detonators, including a connector body. One end of the connector body is provided with a socket, and the other end of the connector body is installed with a terminal assembly. The terminal assembly includes multiple groups of metal terminals installed inside the connector body. A bayonet is provided inside the metal terminal. The inner wall of the bayonet is serrated, and both sides of the inner wall of the bayonet are provided as inclined surfaces. A connecting portion is fixed at one end of the metal terminal.

[0006] By adopting the above technical scheme, the inner wall of the bayonet is set to be serrated. The serrated bayonet has multiple contact points, enabling it to better contact with the external metal plug and improving the contact stability.

[0007] The utility model is further set as follows. The outer wall of the metal terminal is also serrated, and multiple groups of installation grooves are provided at one end of the connector body away from the socket.

[0008] By adopting the above technical scheme, the serrated outer wall of the metal terminal can better cooperate with the installation grooves, so that the metal terminal is more firmly connected to the connector body, and the metal terminal will not easily separate from the connector body.

[0009] The utility model is further set as follows. A limiting block is fixed on the inner wall of the socket.

[0010] By adopting the above technical scheme, the set limiting block can prevent the metal terminal from entering the inside of the socket.

[0011] The utility model is further configured such that an annular groove is provided at one end of the connector body close to the socket.

[0012] By adopting the above technical solution, the annular groove provided facilitates the connection between the connector body and an external plug.

[0013] The utility model is further configured such that a table surface is provided on one side of the outer wall of the connector body.

[0014] By adopting the above technical solution, the provided table surface facilitates positioning during the assembly of the connector body and the housing, and avoids the rotation of the connector body.

[0015] In summary, the main beneficial effects of the utility model are as follows:

[0016] In the utility model, through the bayonet, the connection part and the socket, the inner wall of the bayonet is set to be serrated. The serrated bayonet has multiple contact points, enabling it to better contact an external metal plug, improving the stability of the contact. The outer wall of the metal terminal is also set to be serrated. During installation, the serrated surface of the outer wall of the metal terminal is tightly and fixedly connected with the inner wall of the installation groove, enabling the metal terminal to be firmly fixed inside the installation groove. And the structure is simple and easy to install. The inner wall of the bayonet of the metal terminal is provided with an inclined surface. Through the inclined surface of the bayonet, the external metal plug can be guided. The metal terminal is limited by the provided limiting part to prevent the metal terminal from moving towards the socket position. Description of the Drawings

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0024] The following will describe the embodiments of the present utility model according to its overall structure.

[0025] A split leg wire connector for digital detonators, as Figures 1 - 5 shown, includes a connector body 1. One end of the connector body 1 is provided with a socket 3, and a terminal assembly 2 is installed at the other end of the connector body 1. The terminal assembly 2 includes multiple groups of metal terminals 21 installed inside the connector body 1, and a bayonet 22 is provided inside the metal terminal 21. The inner wall of the bayonet 22 is serrated. The serrated setting of the inner wall of the bayonet 22 can make the connection between the external metal plug and the metal terminal 21 more stable. The two sides of the inner wall of the bayonet 22 are set as inclined planes. A connecting portion 23 is fixed at one end of the metal terminal 21. The serrated setting on the outer wall of the metal terminal 21 can better connect with the connector body 1, making the connection of the metal terminal more firm.

[0026] Please refer to Figure 3 and Figure 5 , the outer wall of the metal terminal 21 is also serrated. Multiple installation grooves 6 are provided at one end of the connector body 1 away from the socket 3. The serrated setting of the outer wall of the metal terminal 21 can better cooperate with the installation grooves 6, so that the connection between the metal terminal 21 and the connector body 1 is closer, and the metal terminal 21 will not easily separate from the connector body 1.

[0027] Please refer to Figure 4 , a limiting block 7 is fixed on the inner wall of the socket 3. By providing the limiting block 7, the metal terminal 21 can be prevented from entering the interior of the socket 3.

[0028] Please refer to Figure 2 , a table surface 5 is provided on one side of the outer wall of the connector body 1. By providing the table surface 5, it is convenient for personnel to hold by hand and increases the contact area between the connector body 1 and the hand.

[0029] Please refer to Figure 2 , an annular groove 4 is provided at one end of the connector body 1 close to the socket 3. By providing the annular groove 4, it is convenient to install a sealing ring on the outer wall of the connector body 1.

[0030] The working principle of the present utility model is as follows: When in use, an external metal plug is connected to the connector body 1. The external metal plug enters the interior of the connector body 1 through the socket 3, and the metal plug enters the inner wall of the bayonet 22 under the action of the bayonet 22 provided on the inclined surface, thereby achieving the purpose of connecting with the metal terminal 2. The serrated setting on the inner wall of the bayonet 22 can make the connection between the external metal plug and the metal terminal 21 more stable. The serrated setting on the outer wall of the metal terminal 21 can better connect with the connector body 1, making the connection of the metal terminal more firm.
