electrical connector

Abstract

The invention discloses an electrical connector. At least two pairs of protrusions are provided on a conductive terminal, wherein the two protrusions of each pair of protrusions protrude opposite to each other along the thickness direction of the conductive terminal, and the two The central axis of the connecting part of the conductive terminal is set as a mirror image along the width direction of the conductive terminal, so that the corresponding reaction forces generated by each convex part against the terminal groove are opposed to each other, so that the conductive terminal is in the terminal The position in the groove will not be skewed, so as to solve the problem that the conductive terminal is inserted obliquely into the terminal groove or the conductive terminal is skewed due to the protrusion during the insertion process, resulting in poor contact of the electrical connector, and it can also ensure that the conductive terminal is not easy to insert into the terminal groove. The case of displacement.

[0002] Today's electronics industry is developing rapidly, so the requirements for the configuration of electrical connectors are getting higher and higher. Conductive terminals, as the most important transmission components, play a key role in the transmission quality of electrical connectors. The terminal is plugged into a preset terminal groove on an insulating body, wherein one end of the conductive terminal is used as a contact section for connecting with an electronic component, and the other end of the conductive terminal is used as a welding section to be welded on a circuit board to realize The signal transmission of the conductive terminal, and the connection section connected between the contact section and the welding section is accommodated in the terminal groove. Generally, the accommodation space in the terminal groove is slightly larger than the overall size of the conductive terminal to facilitate the insertion of the conductive terminal into the terminal groove. The gap between the terminal groove and the conductive terminal is not only easy to make the conductive terminal unstable and easy to loose when the electrical connector is connected, but also because the current conductive terminal tends to be miniaturized and thinner, the conductive terminal is punched in the longitudinal direction. Its contact section is easy to incline relative to the welding section, and it is easy to cause the insertion angle of the conductive terminal to shift (such as oblique insertion) when plugging in, so that there is a risk of friction between the contact section and the inner wall of the terminal groove, resulting in easy deformation of the contact section and affecting the terminal. transmission quality; therefore, to fill the gap between the conductive terminal and the terminal slot, such as figure 1 As shown, generally the front and back surfaces of the conductive terminal 2 are formed with convex shells 2a, 2b, and the convex shells 2a, 2b will be in contact with the inner wall of the terminal groove during the process of inserting the conductive terminal 2 into the terminal groove, thereby ensuring The conductive terminal can be fastened in the terminal groove, but when the conductive terminal 2 is inserted into the terminal groove, when the convex shells 2a, 2b press the inner wall of the terminal groove, a first force in the same direction as the protruding direction of the convex shells 2a, 2b will be generated. , when the inner wall of the terminal groove is squeezed, a first reverse force F1 opposite to the direction of the first force will be generated, so that the entire conductive terminal is inclined towards the direction of the first reverse force F1 during the insertion process ( figure 2 arrow direction), such as figure 2 As shown, the position of the conductive terminal 2 inserted into the terminal groove is not correct, so that the contact section is easy to touch the inner wall of the terminal groove and is displaced and deformed, resulting in a deviation of the contact between the conductive terminal and the electronic component, resulting in poor contact of the electrical connector Phenomenon, affecting the performance stability of the electrical connector
