Detailed Description
The present utility model provides a current detecting device, which is described in further detail below with reference to the accompanying drawings and specific embodiments. Advantages and features of the utility model will become more apparent from the following description and from the claims.
The embodiment provides a current detection device, which comprises two electric conductors, wherein at least one electric conductor is provided with a through hole; the resistor is arranged between the two conductors; and a detection terminal penetrating through the through hole of the conductor. The electrical conductor is made of a metallic material, preferably copper.
Specifically, referring to fig. 1, the detection terminal 10 includes a flange 1 and a rivet 2, and a recess 3 is formed between the flange 1 and the rivet 2. It will be appreciated that the recess 3 is a ring of recesses on the side of the detection terminal. The diameter of the rivet 2 is smaller than the diameter of the flange 1.
Referring to fig. 2, a through hole is provided in the conductor 20, through which the detection terminal 10 penetrates. In order to stabilize the connection between the detection terminal 10 and the conductor 20, the hole diameter of the through hole on the conductor 20 is not larger than the diameter of the lower end of the rivet 2 and smaller than the diameter of the flange 1. Thus, when the detection terminal 10 is inserted into the through hole, a part of the material of the conductor 20 is sunk into the recess 3 of the detection terminal 10, thereby increasing the contact area of the detection terminal and the conductor and having the functions of limiting and locking, preventing the detection terminal from falling.
In order to facilitate insertion of the detection terminal 10 into the through hole of the conductor 20, the lower end of the rivet 2 is provided with a chamfer 4, the chamfer 4 being shaped to guide the rivet 2 into the through hole.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments. Even if various changes are made to the present utility model, it is within the scope of the appended claims and their equivalents to fall within the scope of the utility model.
