Description

Electrical connector

The present invention provides an electrical connector, in particular, the two-piece upper and lower assembly manner of the insulating seat body can be used to position the elastic member between the base and the outer cover to form an isolation. When the contact terminal is pressed, the elastic member can be avoided. The contact with the conductive terminal generates an unstable conduction path, and has the effect of stabilizing the current conduction path and improving the transmission efficiency.

According to the rapid development of electronic technology and multimedia information, electronic devices such as notebook computers, tablet computers, and smart phones have become commonplace in all corners of society, and the design of electronic devices tends to be light, thin and short. Therefore, the electronic component structure on the internal circuit board of the electronic device must be reduced and more precise, and the overall structural strength needs to be strengthened to meet the current development trend.

Moreover, in general, electronic devices generally use a connector to achieve connection with a circuit board, and the connector is mostly connected to a cable and connected to a plurality of signal terminals or power terminals inside the connector. Another mating connector can transmit signals or power through the board to the control circuit, and as the size of the connector becomes smaller, various types of connectors are developed, such as a probe type (Pogo Pin). For the connector, please refer to the ninth and tenth drawings, which are respectively an exploded perspective view and a side cross-sectional view of the conventional electrical connector, wherein each of the receiving slots A1 of the insulating housing A respectively accommodates a metal probe. B, conductive seat C and pressure The spring D is formed by the turning method, and has a contact end B1 which can be worn outside the receiving groove A1 and a ring-shaped abutting end B2 having a large outer diameter, and the conductive seat C The joint portion C1 can be connected to the circuit board. After the side wall C2 extends upward on both sides of the joint portion C1, an arm C3 is bent and extended downward, and the compression spring D is located at the conductive seat C. Between the two side walls C2, and the upper end of the compression spring D abuts against the annular abutting end B2 of the metal probe B, and the lower end of the compression spring D is in contact with the conductive seat C.

When the contact end B1 of the metal probe B is pressed into the insulating housing A by an external force, it is pushed by the compression spring D to be elastically deformed, and the annular end of the metal probe B abuts against the end B2 and conducts. The two arms C3 of the seat C are in contact with each other, thereby achieving the purpose of electrical connection. However, the metal probe B is made by using a turning method. Due to the small volume of the metal probe B, not only the annular abutting end is caused. B2 processing is quite labor intensive and difficult, so that the cost required for the overall manufacturing can not be effectively reduced, and the metal probe B is easy to cause structural defects and damage during the processing; and, due to the compression spring D The two ends are in contact with the metal probe B to form electrical contact with the conductive base C, so that the compression spring D generates an unstable conduction path when the high-current power source or the high-frequency signal is transmitted, and the metal is subjected to the compression spring D. Under the push of the probe B, the contact part will wear and cause impedance, which will affect the stability of the current conduction path and the noise interference phenomenon. It will also cause additional energy loss to make the overall transmission efficiency worse. This industry has been redesigned to effectively solve it.

Therefore, in view of the above-mentioned problems and shortcomings, the new creators have collected new information and evaluated them through various evaluations and considerations, and have used the trial and modification of many years of R&D experience in this industry to design a new type of electrical connector. Born.

The main purpose of the present invention is to integrate an outer cover at the top of the base of the insulating base, and to position a conductive terminal of the first terminal group in at least one terminal slot at the top of the base, and the top of the outer cover has a plug connector. And the contact terminal formed by the second terminal group metal sheet is respectively positioned in the through passage on the plug connector, and the contact terminal is combined with the rubber seat, and the elastic member is sleeved on the rubber seat, when the contact terminal is When the conductive portion is pressed, the resisting portion of the rubber seat is pushed down to the elastic member to be elastically compressed and deformed, and the abutting portion of the contact terminal is pressed downward to contact the contact portion of the conductive terminal to form electricity. Sexual connection, the two-piece upper and lower assembly manner of the insulating seat can position the elastic element between the base and the outer cover to form an isolation, so as to avoid an unstable conduction path between the elastic element and the conductive terminal. Ensure the stability of the overall current conduction path and prevent noise interference.

The secondary purpose of the present invention is that when the conductive portion of the contact terminal is subjected to the pressing force, the abutting portion thereof is pressed downward to contact the contact portion of the conductive terminal, and is pushed against the opposite elastic portion of the contact portion. The arm is elastically deformed outwardly, so that the abutting portion can be pressed into the clamping space formed between the two elastic arms, and the two contact surfaces of the two elastic arms relatively clamped on the outer surface of the abutting portion can be contacted for a long time. The resulting wear is effective in reducing the impedance, temperature rise and noise interference caused by the transmission of high-current power or high-frequency signals, so that the contact terminals and the conductive terminals can reduce the additional energy loss and stabilize Current conduction path and the effect of improving overall transmission efficiency.

Another object of the present invention is that the conductive terminals of the first terminal group and the contact terminals of the second terminal group are integrally formed by stamping a metal sheet, which not only reduces the labor time required for processing, but also reduces manufacturing. Cost, and the contact terminal is formed by plastic injection molding combined with a rubber seat, and the elastic element can be prevented from directly contacting the contact terminal to form a contact impedance. The hollow portion of the contact terminal can also be filled through the rubber seat to ensure the overall structural strength, thereby achieving structural stability, mass production, and improved manufacturing quality and yield.
