Circuit board connector

Abstract

The invention discloses a circuit board connector which comprises an insulation body, conductive terminals arranged on the insulation body and a metal shell wrapping the insulation body, wherein a plug-in hole is formed in the metal shell; the insulation body comprises a main body part and a clapper which forwards extends from the main body part into the plug-in hole; the conductive terminals comprise contact parts distributed on the surface of the clapper; each conductive terminal extends towards the outside of the insulation body, thus forming a welding part; each conductive terminal is provided with a connection part; the connection parts are connected with the contact parts and the welding parts respectively; the insulation body is provided with at least one molding cavity; the connection parts of at least part of the conductive terminals are exposed in the molding cavity; the molding cavity is provided with an externally exposed surface; the molding cavity is filled with non-conductor stuffings with a sealing effect. According to the circuit board connector, the conventional mode that only a waterproof sealing ring is arranged at the periphery of the connector in a sleeving manner is changed into the novel mode that the sealing stuffings are arranged for a structure inside the connector, so that the waterproofing performance and the airtightness are improved, and a more precise waterproofing effect is achieved.

Description

technical field [0001] The invention relates to a circuit board connector, in particular to a circuit board connector with waterproof function. Background technique [0002] Since the USB Type-C connector has reversible insertion function and high-frequency transmission rate, it is more and more widely used in electronic products, especially when it is soldered on a circuit board in the electronic product, it is regarded as a circuit board connector. The USB C-type connector usually includes an insulating body, two rows of conductive terminals arranged on the insulating body, and a metal shell covering the insulating body. The metal shell is provided with a socket hole for receiving a docking connector. There is a tongue plate located in the insertion hole, and the conductive terminals are arranged on the upper and lower surfaces of the tongue plate for contacting with the mating connector. [0003] Considering the different environments in which electronic products are use...

AI Technical Summary

Problems solved by technology

However, when the electrical connector is cooled to room temperature after the high-temperature circuit board soldering process, a small gap is likely to be formed between the terminal of the metal conductive material and the insulating body with a different coefficient of thermal expansion (CTE), resulting in a decrease in waterproof performance

With the increase of use time or under high temperature and high humidity conditions, moisture or water vapor will enter the electronic product through the gap through the contact part of the conductive terminal exposed on the surface of the tongue plate, thereby causing damage to the electronic product
