Detailed Description
The invention is further described with reference to the following figures and specific examples.
Referring to fig. 3 to 7, a connection structure for a ground terminal includes a ground pad 2 and a current carrier 1 disposed on the ground pad 2, the ground pad 2 is disposed with a main elastic arm 21 and a side elastic arm 22 disposed on at least one side of the main elastic arm 21, a free end of the main elastic arm 21 is bent to form a main abutting portion 23, a free end of the side elastic arm 22 is bent to form a side abutting portion 24, the main abutting portion 23 and the side abutting portion 24 are bent toward the same side, an insertion groove 26 is formed between the main abutting portion 23 and the side abutting portion 24, the current carrier 1 is clamped in the insertion groove 26, and the current carrier 1 and the insertion groove 26 are in interference fit, when the current carrier 1 is clamped in the insertion groove 26, a body of the side elastic arm 22 is elastically deformed, and the side abutting portion 24 moves toward the main abutting portion 23, the side contact portion 24 contacts the carrier fluid 1. And after the current carrier 1 and the grounding piece 2 are assembled, the grounding piece is installed in a track grounding product.
The body of the side elastic arm 22 is bent towards one side of the side abutment 24 to form a bend 27, the bend 27 being in the shape of an arc, the bend 27 deforming so that the side abutment 24 has a tendency to exert an upward force on the current carrier 1.
When the current carrier 1 abuts against the side abutting part 24, the acting force pushing the side abutting part 24 acts on the body of the side elastic arm 22, and because the center of the bending part 27 is located on the same side of the acting force of the side abutting part 24, when the body of the side elastic arm 22 receives the acting force, the elastic deformation is more likely to occur, so that the side abutting part 24 has a tendency of exerting an upward force on the current carrier 1.
In the present embodiment, the main elastic arm 21 is provided with the side elastic arms 22 on both left and right sides, and the two side elastic arms 22 are symmetrically arranged with respect to the main elastic arm 21. The two side elastic arms 22 are respectively bent to form the side abutting parts 24, the two side abutting parts 24 are located on the same plane, an insertion groove 26 is formed between the two side abutting parts 24 and the main abutting part 23, and when the current carrier 1 is clamped in the insertion groove 26, the main abutting part 23 and the two side abutting parts 24 both abut against the current carrier 1, so that the connection between the current carrier 1 and the grounding piece 2 is more stable.
In the connection structure of the invention, the current carrier 1 is clamped in the insertion groove 26, so that the assembly between the grounding piece 2 and the current carrier 1 can be realized, the installation is convenient, in addition, the current carrier 1 is in interference fit with the insertion groove 26, after the current carrier 1 is inserted into the insertion groove 26, the main abutting part 23 and the side abutting part 24 clamp the current carrier 1, so that the connection between the current carrier 1 and the grounding piece 2 is stable, the main abutting part 23 is formed by bending the main elastic arm 21, the side abutting part 24 is formed by bending the side elastic arm 22, the structure is simple, the processing and forming are convenient, the production cost is low, in addition, the connection between the current carrier 1 and the grounding piece 2 is stable, the loosening is not easy to generate, because the body of the side elastic arm 22 is bent towards one side provided with the side abutting part 24 to form the bending part 27, so that the side abutting part 24 has the tendency of applying upward force to the current carrier, when the current carrier 1 is engaged in the insertion groove 26, the bent portion 27 is deformed, and the side abutting portion 24 tends to apply an upward force to the current carrier 1, so that the side abutting portion 24 abuts against the current carrier 1 to clamp the current carrier 1, and when the current carrier 1 tends to loosen from the insertion groove 26, the bent portion 27 is deformed, and the side abutting portion 24 always applies an upward force to the current carrier 1, so that the side abutting portion 24 always abuts against the current carrier 1, and the looseness of the current carrier 1 is prevented by the engagement of the side elastic arm 22 and the side abutting portion 24.
As an improvement of the present invention, a limiting hole 11 is formed in the upper end surface of the current carrier 1, a limiting block 25 matched with the limiting hole 11 is arranged on the main elastic arm 21, and when the current carrier 1 is clamped in the insertion groove 26, the limiting block 25 is clamped in the limiting hole 11. Through the cooperation of stopper 25 and spacing hole 11, current carrier 1 is difficult for relative horizontal or longitudinal movement between the grounding piece 2 for it is stable to be connected between current carrier 1 and the grounding piece 2. The side wall of the carrier fluid 1 is provided with an avoiding groove 12 matched with the main elastic arm 21. When the carrier 1 card is located when the ground lug 2 is gone up, main elastic arm 21 stretches into in the dodging groove 12 for the carrier 1 with can not take place to interfere between the main elastic arm 21, the carrier 1 can be bigger with main elastic arm 21 direct contact face. Gaps are formed in the width direction between the main elastic arm 21 and the two side elastic arms 22 on the left and right sides, respectively. So that the main elastic arm 21 and the side elastic arm 22 can be elastically deformed independently to ensure good elasticity and good contact with the carrier fluid 1.
