Electric connector and manufacturing method thereof

Abstract

The invention discloses an electric connector and a manufacturing method of the electric connector. A connecting piece is embedded between the side edge of an insulating body and the outer side of a row head terminal or a row tail terminal in a first terminal row; a gap is formed between the connecting piece and the row head terminal or the row tail terminal, that is to say, the connecting piece does not contact with the adjacent row head terminal or row tail terminal. Therefore, the width of the row head terminal or the row tail terminal is not increased. The high-frequency transmission rateof the first terminal row is ensured. The electric connector which does not influence terminal transmission quality, is convenient to process and stable in structure and has high-frequency transmission performance can be formed.

Description

【Technical field】 [0001] The invention relates to an electrical connector and a manufacturing method thereof, in particular to an electrical connector suitable for high-frequency transmission and a manufacturing method thereof. 【Background technique】 [0002] Electrical connectors are mainly used to bridge two conductors on a circuit so that current or signals can flow from one conductor to another conductor. It is widely used in a variety of electrical circuits, and plays the role of connecting or disconnecting current or signals, while the existing electrical connector structure generally includes a terminal block and an insulating body embedded and formed on the terminal block , but in the process of embedded molding, the terminal block is easily affected by the impact of the liquid insulating material and deviates from the predetermined position, which leads to the weak connection between the terminal block and the injection-molded insulating body. In order to solve the ...

It is widely used in a variety of electrical circuits, and plays the role of connecting or disconnecting current or signals, while the existing electrical connector structure generally includes a terminal block and an insulating body embedded and formed on the terminal block , but in the process of embedded molding, the terminal block is easily affected by the impact of the liquid insulating material and deviates from the predetermined position, which leads to the weak connection between the terminal block and the injection-molded insulating body. In order to solve the above problems, technicians in this industry generally An auxiliary support foot connected to the side edge of the terminal row is added to the terminal row formed by stamping to further strengthen the fixing between the terminal row and the insulating body. For example, the Chinese patent with the notification number CN201690022U discloses a connector terminal support structure, such as figure 1 As shown, there are auxiliary support feet 34 on the two outermost terminals among the terminals, and support pins 33 connected with the auxiliary support feet 34 extend inwardly on the support frame, and the support pins 33 and the auxiliary support feet There is a breaking line 31 between 34, and the supporting pin 33 is formed in advance. When the plastic seat and the terminal are assembled, the supporting pin 33 can be broken off, but the above-mentioned technology has the following disadvantages: first, the auxiliary supporting pin 34 is due to the The outermost terminals are connected together. After an insulating body is injection-molded on the terminal and the bracket is removed, the auxiliary support feet 34 will always be connected to the outermost terminal and embedded in the insulating body together, so that Equivalent to an increase in the width of the outer terminal, it is easy to reduce the transmission rate of the signal terminal in actual use, so that the electrical connector cannot achieve high-frequency performance
