Detailed Description

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The prior art is as follows:

a conventional bipolar female DC connector is shown in fig. 1, which includes: the existing shell 101, the existing power PIN301 and the existing rubber core 601 realize the 2-pole function through the contact of the male shell and the female shell, and are not flexible to use;

referring to fig. 2 to fig. 7(B), the present invention provides a technical solution: a three-pole female DC connector.

In the scheme, the three-pole female-end DC connector comprises a shell 1, a rubber shell 2, an insulating structure 6 and a power supply PIN3, wherein the rubber shell 2 is sleeved inside the shell 1, the insulating structure 6 is positioned at the bottom of the shell 1 and used for plugging an opening at the bottom of the shell 1, and the power supply PIN3 penetrates through the insulating structure 6 and then extends into the shell 1;

the insulating structure 6 has a negative contact structure thereon.

Referring to fig. 3, in particular, when the installation book is installed, the following steps are performed:

the first step is as follows: the insulating structure 6 is sleeved on a power supply PIN3, and a contact pole of a power supply PIN3 is positioned outside the power supply PIN 3;

the second step is that: subsequently installing a negative contact structure; in the installation process, two contact pins of the negative electrode contact structure need to penetrate through the insulation structure and then are exposed outside the insulation structure;

the third step: fixedly sleeving the rubber shell 2 on the negative electrode contact structure for insulating the shell and the negative electrode contact structure;

the fourth step: and finally, fixedly sleeving the shell 1 on the rubber shell 2 to finish final installation.

Wherein the negative contact structure comprises a first negative PIN4 and a second negative PIN 5;

the first negative PIN4 and the second negative PIN5 are both located inside the rubber shell.

It should be noted that the three-pole female terminal is composed of a first negative PIN4, a second negative PIN5 and a positive PIN, and can realize a three-pole function by matching with the three-pole male terminal;

the two-pole type function is realized by matching with the two-pole type public end, so that the limitation is smaller, and the use is more flexible;

the negative electrode contact structure and the shell 1 are separated by a rubber shell 2, and the bottom of the negative electrode contact structure is sealed by an insulating structure 6.

Specifically, the second negative PIN5 is sleeved inside the rubber shell 2, is isolated from the shell 1 through the rubber shell 2, and surrounds the power supply PIN 3.

Specifically, the insulating structure 6 is a disc-shaped rubber core, and the end face of the insulating structure is provided with a socket for assembling the power supply PIN3 with the first negative electrode PIN4 and the second negative electrode PIN 5.

Specifically, the bottom of the housing 1 has an opening for sealing in cooperation with the flange structure.

Specifically, the edge part of the bottom of the rubber shell 2 is contacted with the end face of the rubber core.
