By forming an insulating part in the insulating housing that extends to the front of the head end of the conductor, when an operator accidentally inserts a finger into the insulating housing of the connector, the insulating part will first block the finger and continue to the inside of the cavity of the insulating housing Insertion prevents the fingers from contacting the conductors in the insulating housing, thereby preventing the operator's fingers from getting electric shock, and realizing the safe operation during the electrical connection process.

Of course, with regard to the arrangement of the insulating member in the insulating housing, in the finger-touch proof connector of the invention, the insulating member is a bump extending in the horizontal direction, and the insulating member is located at a level higher than the first A horizontal plane where the conductive part is located.

In addition, in the anti-finger touch connector, the conductive body includes:

The transverse part has a middle slot, and the transverse part is the first conductive part;

The vertical part is connected with the horizontal part, and the vertical part is formed with a pin located outside the cavity of the insulating housing, and the pin is the second conductive part.

In order to enhance the firmness of the insulating part when it is arranged in the insulating housing, in the finger-proof connector, the insulating part can pass through the middle slot and divide the transverse part into parts located on the left side of the insulating part. the left conductor part on the side and the right conductor part on the right side of the insulating member. Wherein, as a realization structure for assembling the conductor into the insulating housing, the back of the insulating housing is formed with a first opening for the left conductor part to penetrate into the cavity and a first opening for the right conductor part to penetrate into the cavity A second opening in the body.

Of course, in order to improve the processing efficiency, in the finger-resistant connector, the insulating component is integrally formed on the inner surface of the insulating housing cavity. Wherein, the insulating member may be a rectangular parallelepiped or other shapes.

Compared with the prior art, the present invention has the advantage that: by forming an insulating part in the insulating housing extending to the front of the head end of the conductor, when an operator accidentally inserts a finger into the insulating housing of the connector, the insulating part can be removed. The fingers will be blocked first and continue to be inserted into the cavity of the insulating housing, which prevents the fingers from contacting the conductors in the insulating housing, thereby preventing the operator's fingers from being electrocuted and realizing safe operation during the electrical connection process.

Detailed ways

The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

As shown in Figs. 1-2, this embodiment provides a connector assembly formed by three finger-resistant connectors. Specifically to any finger-resistant connector in the connector assembly, it includes an insulating housing 1 and a conductor 2. The insulating housing 1 has a cavity 10 with an opening at one end, and the opening is used for a plug to enter and be inserted into the connector. In the cavity 10, a first opening 11 and a second opening 12 are formed on the back of the insulating housing 1. Of course, the first opening 11 and the second opening 12 here can also communicate with each other, so as to be designed as a single opening. The form of holes; the conductor 2 has a first conductive portion 21 and a second conductive portion 22, the first conductive portion 21 of the conductor 2 is located in the cavity 10 of the insulating housing, and the second conductive portion 22 of the conductor 2 is located in The outer side of the insulating housing 1; specifically, as shown in FIGS. 2 to 4 , the conductor 2 includes a transverse portion with a middle slot 210 and a vertical portion connected to the transverse portion, and the transverse portion is the first conductive portion 21. The vertical portion is formed with a pin 221 located outside the cavity 10 of the insulating housing 1, and the pin 221 is the second conductive portion;

An insulating member 3 extending toward the opening of the cavity 10 is integrally formed on the inner wall of the cavity 10 of the insulating housing 1 . The structure of the insulating member 3 is shown in FIG. 1 , FIG. 3 and FIG. 5 . The insulating member 3 passes through the middle slot 210 and divides the lateral portion into a left conductor portion 211 on the left side of the insulating member 3 and a right conductor portion 212 on the right side of the insulating member 3 . During the assembly process, the left conductor part 211 of the lateral part penetrates into the cavity 10 of the insulating housing through the first opening 11 , and the right conductor part 212 of the lateral part penetrates into the insulating housing through the second opening 12 In the cavity 10 of the casing, the firmness of the conductor 2 when disposed in the insulating casing 1 is enhanced. The insulating part 3 here is a bulge extending in the horizontal direction, and the bulge can be a rectangular parallelepiped with one side wall connected to the inner side wall of the insulating shell; The level where the component 3 is located is higher than the level where the first conductive portion 21 is located.

Referring to FIG. 5, there is shown a schematic diagram of the state when the plug is inserted into the connector in a normal operating state. Referring again to FIGS. 6 and 7 , by forming the insulating part 3 in the insulating housing 1 extending to the front of the head end of the conductor 2, the operator can accidentally insert the finger 4 into the insulating housing 1 of the connector. At this time, the insulating component 3 will first block the finger 4 and continue to insert it into the cavity 10 of the insulating housing 1, so as to prevent the finger 4 from contacting the conductor 2 in the insulating housing 1, thereby preventing the operator's finger from getting an electric shock and realizing the electrical shock.
