Ceramic piece, USB socket connector and formation method of USB socket connector

Abstract

The invention relates to a ceramic piece, a USB socket connector and a formation method of the USB socket connector. The socket connector comprises an insulation body, a plurality of conductive terminals and the ceramic piece, wherein the insulation body comprises a main body part and a first abutting part, the first abutting part forwards extends from the main body part, the ceramic piece comprises two arm parts which are horizontally parallel to each other, the arm parts and the first abutting part form a tongue plate, a latch groove and a latch convex part are arranged on an outer side surface of each arm part, the latch convex part is arranged in front of the latch groove, the insulation body is arranged on the ceramic piece by injection molding, and the two arm parts are provided with first cutting surfaces for cutting connection parts of the arm parts and a first material bridge before the injection molding of the insulation body. The first material bridge is connected with the two arm parts, thus, the structural strength of the ceramic piece is favorably improved, and the deformation of the ceramic piece and the arm parts thereof can be substantially reduced during the injection, sintering and post-treatment process of the ceramic piece.

Description

technical field [0001] The invention relates to a USB socket connector, in particular to a ceramic part using ceramic materials, a USB socket connector and a forming method thereof. Background technique [0002] With the rapid development of science and technology in the electronics industry, the size of electronic products is becoming more and more thinner and shorter, which requires the components of electronic products to be smaller and smaller, and connectors are the first to bear the brunt. Due to the requirement for a smaller size of the new generation of USB Type-C connectors, this leads to better mechanical performance requirements and more difficult product design. In order to face thinner and thinner equipment and ensure the reliability of product structure, major manufacturers have launched corresponding structural designs. [0003] For the prior art related to this case, you can refer to a USB socket connector disclosed in China Utility Model Patent Announcement...

Problems solved by technology

[0003] The prior art related to this case can refer to a USB socket connector disclosed in China Utility Model Patent Announcement No. CN205944560U, which includes a ceramic support and a terminal module and a metal shell, the supporting member includes a main body and a tongue protruding forward from the main body, grooves are provided on the upper and lower surfaces of the tongue, two terminal modules are provided, and each terminal module includes a row of conductive terminals and The insulating block is injection molded on the conductive terminal. The conductive terminal has a contact part protruding forward from the insulating block. The contact parts are accommodated in the corresponding grooves of the tongue plate one by one. Since the tongue plate is made of ceramics, the toughness of ceramics is poor. When the plug connector is docked, especially when it is inserted obliquely, the tongue plate is easily broken after being pressed by the USB plug connector, which affects the application function and service life of the USB socket connector
