Description

Electric connector (two)

The present invention provides an electrical connector, especially an electrical connector that has a male-female switching function, has a stable fixing effect of the male-female connector, and can reduce the electromagnetic interference between the female connector and the mating connector.

According to this, the existing electrical connector generally includes a metal shell and a terminal block arranged in the metal shell. The terminal block is provided with a plurality of terminals for mating. The metal shell can be used to plug in another corresponding electrical connector and connect it. Ground to shield electrical signal interference. Generally speaking, the metal shell is mostly made of a metal sheet, which can be bent into a tube, cylinder or ring by sheet metal processing so that the terminal block can be set in it. However, the current electrical connectors are small in size and the metal shell The joints easily cause electrical signal leakage and electromagnetic interference, and reduce the efficiency and stability of the electrical connector to transmit signals.

Especially when the electrical connector has a switching function, it is more often because the connection and fixing structure of the male connector and the female connector is too simple, for example, it only provides a single-directional fixing action, or a single set of component clamping effects. Therefore, it is very easy to cause defects in the connection and fixation of the male connector and the female connector due to process negligence or external force collision, which causes the seam problem between the metal shells to be more obvious, which in turn causes serious electromagnetic interference problems.

In addition, when the male connector and the female connector are mated correspondingly, most of the male connectors usually have a plurality of fixing ports on their metal shells for correspondingly snapping on the female connector. However, these fixing ports are also one of the root causes of the magnetic field leakage. However, the structure of the fixing fixing port on the female connector (usually a shrapnel structure) cannot provide any shielding effect to the fixing port. unfortunately.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the creators of the present invention and related manufacturers engaged in this industry urgently want to study and improve.

Therefore, in view of the above-mentioned deficiencies, the creator of the present invention collected relevant information, evaluated and considered from multiple parties, and based on years of experience in this industry, through continuous trials and modifications, he designed this type of male-female transfer It is the patent of the invention of electrical connectors that have functions, and the fixing effect of the male and female connectors is stable, and can reduce the electromagnetic interference of the female connector and the mating connector.
