Embodiment

[0023] Combine Figure 1 to Figure 4 , The present invention is a new type of composite terminal, which includes a terminal body, a thermal contact piece 3, a connecting end 4, and a retractable spring 6. The terminal body includes a tail connecting section 1 and a front contact section 2. The terminal body has a strip-shaped plate structure, the tail connecting section 1 is connected with the front contact section 2, and the two sides of the tail connecting section 1 are arranged in parallel with each other and are bent at 90°. Preferably, a sliding groove 8 along the length of the terminal body is provided on the tail connecting section 1. The thermal touch sheet 3 is connected to the front contact section 2, and the contact surface of the thermal touch sheet 3 and the front contact section 2 is a stepped structure that cooperates with each other. The thermal contact piece 3 is made of nickel-chromium alloy, and the surface is coated with a polytetrafluoroethylene coating. ...

Abstract

The present invention discloses a new-type composite terminal, which comprises a terminal body, a thermal sensing contact, a connecting terminal and a telescopic spring. The terminal body comprises a tail connecting section and a front contacting section. The thermal sensing contact is connected with the front contacting section. The thermal sensing contact and the contacting surface of the front contacting section are of a stepped shaped structure that cooperates with each other. The thermal sensing contact is made of the nickel-chromium alloy and its surface is coated with a poly tetra fluoroethylene layer; the bottom of the thermal sensing contact is connected with the connecting terminal; and the connecting terminal is connected with the telescopic spring. The telescopic spring is made of memory alloy materials and is in the form of a spiral structure spirally arranged along the length of the terminal body; and the telescopic spring shortens and deforms along the axial direction of the spiral structure after its temperature reaches the phase transition temperature. The composite terminal of the invention has a reasonable structure, is good in strength, does not deform easily, has a good connection temperature and achieves good safety.

Description

Technical field [0001] The invention relates to the field of terminals, in particular to a fast new type composite terminal. Background technique [0002] Terminals, which are mainly used to transmit signals and conduct electricity, play the role of connection and conduction. Due to its thin thickness and weak structure, the terminals are prone to poor contact, or bending and deformation of the contact parts, which can easily lead to short circuit or local overheating of the terminal. In severe cases, a fire may even cause a safety accident. Summary of the invention [0003] In order to solve the above technical problems, the present invention provides a new type of composite terminal, which changes the original single use of copper materials and adopts a composite structure to solve the problems of weak structure of traditional terminals, poor contact and poor safety. [0004] In order to achieve the above objective, the technical solution of the present invention is as follows: a...
