Electric connector with function of short-circuit protection

Abstract

The invention relates to an electric connector with a function of short-circuit protection, and the connector comprises a short-circuit mechanism. The short-circuit mechanism comprises an insulator and contact pieces. The insulator is provided with contact piece installation holes which are corresponding to the contact pieces. The insulator is also provided with a printed board which is provided with at least two printed board contact parts. The printed board is also provided with printed board circuits which are respectively connected with the corresponding printed board contact parts. Each contact piece is provided with a contact piece contact part which is in electrical contact connection with the corresponding printed board contact part. Each contact piece is provided with a short-circuit position and a short-circuit elimination position, wherein the short-circuit positions are used for enabling the contact piece contact parts to be in electrical contact connection with the corresponding printed board contact parts, and the short-circuit elimination positions are pushed by adaptive contact pieces of an adapter connector to move backwards from the short-circuit positions until the contact piece contact parts are separated from the corresponding printed board contact parts. Reset springs are disposed between the printed board or the insulator and the corresponding contact pieces. The electric connector provided by the invention solves the problems in the prior art that a short-circuit mechanism is complex in structure and the short circuit between specific contact pieces cannot be achieved.

Description

technical field [0001] The invention relates to an electrical connector with short-circuit protection function. Background technique [0002] In some special application requirements, the electrical connector is required to have a self-short-circuit function to enhance the safety of the system. The self-short-circuit function means that some or all of the contacts are required to be in a short-circuit state when the connector and the adapter connector are not mated. In the connected state, after the connector and the adapter connector are mated, it is required to release the short circuit, and the connector and the adapter connector can transmit signals normally. The existing electrical connector with short-circuit protection function such as the "four-core connector with short-circuit protection function" disclosed in Chinese patent CN202550146U, the four-core connector includes a housing and a short-circuit mechanism arranged on the housing , the short-circuit mechanism i...
