Embodiment

[0023] combine Figure 1 to Figure 4 , The present invention is a new composite terminal, including a terminal body, a heat-sensitive contact piece 3 , a connecting terminal 4 , and a telescopic spring 6 . The terminal body includes a tail connection section 1 and a front contact section 2 . The terminal body is in the shape of a strip plate, the tail connection section 1 is connected to the front contact section 2, and the two sides of the tail connection section 1 are arranged parallel to each other and bent at 90°. Preferably, a sliding groove 8 along the length direction of the terminal body is provided on the tail connection section 1 . The heat-sensing sheet 3 is connected to the front contact section 2, and the contact surface between the heat-sensing sheet 3 and the front contact section 2 is a stepped structure that cooperates with each other. The heat-sensitive contact piece 3 is made of nickel-chromium alloy, and the surface is coated with polytetrafluoroethylene ...

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 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 the thin thickness and weak structural strength of the terminal, it is easy to have poor contact, or the contact part is bent and deformed, which can easily lead to short circuit or local overheating of the terminal, and in severe cases, even fire and safety accidents. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a new type of composite terminal, which changes the original situation of single use of copper material, adopts a composite structure, and solves the problems of weak structural strength, poor contact and poor safety of the traditional terminal. [0004] In order to achieve the above object, the technical soluti...
