(3) Beneficial effects

The multi-core male and female plug-in stable connector of the utility model has the following advantages:

1. A guide mechanism is set around the male plug and the female plug. Through the cooperation of the guide column and the guide hole, the slender and difficult-to-observe pins can be correctly inserted into the corresponding jacks, so the insertion is very convenient. The bending deformation of the contact pins, or the problem of not inserting the contact pins into the corresponding sockets is avoided, and the stability is improved.

2. The size of the guide post and the guide hole are different, especially the diameter and length, which can prevent the positive and negative positions of the male plug and the female plug from being inserted incorrectly, and it is very convenient to use.

3. Both the edge of the opening of the guide hole and the edge of the end face of the guide post are provided with chamfers, so it is more convenient for the guide post to be inserted into the guide hole.

4. The protective wall is connected with the guide sleeve and has an integrated structure, so the strength of the guide sleeve is improved, and the positions of the guide post and the guide hole are further stabilized.

5. The outer circular surface of the guide column is provided with a plurality of annular evenly distributed notches. When the guide column and the guide hole are mated and plugged in, the dust in the guide hole can be squeezed into the notch groove to prevent the dust from being stuck The problem of inconvenient insertion and removal occurs between the guide post and the guide hole.

Detailed ways

Below in conjunction with accompanying drawing and embodiment, the specific embodiment of the utility model is described in further detail. The following examples are used to illustrate the utility model, but not to limit the scope of the utility model.

As shown in Figures 1-4, a multi-pin male-female plug-in stable connector includes a male plug 1 provided with pins 15 and a female plug 2 provided with jacks 25, the male plug 1 and the female plug 2. There are guide mechanisms on the left and right sides of the exterior, and the guide mechanisms include guide holes and guide posts that are mated and inserted. The shape of the guide holes and guide posts is circular, and the insertion direction of the guide holes and guide posts is consistent with The insertion direction of the pin and the socket is consistent, and the guide hole and the guide post correspond to the guide hole a11, the guide post a21, the guide hole b12 and the guide post b22 in the figure. Positioning as the base point, as long as the guide column a21 and the guide column b22 are inserted into the guide hole a11 and the guide hole b12, the small and many pins 15 can be inserted into the corresponding sockets 25, so the operation is very convenient and avoids the The bending deformation of the pins, or the problem of not inserting the pins into the corresponding sockets occurs, improves the stability.

The size of the guide hole a11 and the guide hole b12 in the two guide mechanisms are different, specifically referring to the diameter and length. The positive and negative position of the female plug is wrongly inserted, which is very convenient to use.
