DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

As shown in Figures 1-5, the utility model provides an 18-pin high-precision male connector, which is mainly used for an electronic connector. It connects two circuit boards or devices through 18 internal pins to complete the transmission of current and signals between each other. At the same time, it contacts the two first terminals 4 with longer lengths in advance to play a grounding role, ensuring the stability of the signal when the second terminal 5 is plugged in. The specific structure mainly includes a shell 1 with conductive ends. The shell 1 serves as the outer shell of the entire connector and mainly protects the internal structure. The openings at both ends of the shell 1 are of different sizes. The end with a larger opening is used for assembling the rubber core, and the end with a smaller opening is used as the male connection part.

The housing 1 has a removable first rubber core 2 clamped inside, and the first rubber core 2 is connected to two second rubber cores 3 clamped and fixed from one side. The first rubber core 2 connected in the housing 1 and the second rubber core 3 connected in the first rubber core 2 are both removable structures. Therefore, when fixed in the housing 1, the user can insert and fix the first terminal 4 and the second terminal 5. When assembling the first rubber core 2, the first rubber core 2 is assembled on the side with a larger opening of the housing 1. The housing 1 is provided with two upper and lower first clamping holes 7, and the surface of the first rubber core 2 is provided with upper and lower first clamping holes 7. Two first clamping blocks 8 are inserted into and fixed in the first clamping holes 7 after sliding, and the first clamping blocks 8 are slid down and fixed in the first clamping holes 7 in a reverse hook structure. The second rubber core 3 is assembled in the first rubber core 2 in the same way. A communicating clamping groove 9 is provided at the position where the first rubber core 2 is assembled with two second rubber cores 3 at the same time. Two second clamping holes 10 are provided at the top and bottom of the inner wall of the clamping groove 9. At the same time, two second clamping blocks 11 are inserted into and fixed in the second clamping holes 10 after sliding are provided on the contacting side of the second rubber core 3 and the second clamping holes 10. The second clamping blocks 11 are slid down and fixed in the second clamping holes 10 in a reverse hook structure.

The two second rubber cores 3 are staggeredly connected, and an anti-stuck position 14 is provided at the connection. The two second rubber cores 3 are staggeredly connected to form a plurality of angled portions that are conducive to assembly and fixation. The two second rubber cores 3 will not be loose after assembly. There are two anti-stuck positions 14 provided on the connection surface of each second rubber core 3. The anti-stuck positions can also play a role of mutual fixation, effectively strengthening the connection between the two second rubber cores 3.

Each of the two second rubber cores 3 is interspersed with a first terminal 4 and at least two second terminals 5, one end of the first terminal 4 and the second terminal 5 passes through the first rubber core 2 and extends forward, and the forward extension length of the first terminal 4 is greater than the forward extension length of the second terminal 5. In the present technical solution, each of the two second rubber cores 3 is interspersed with a first terminal 4 and eight second terminals 5, so the entire connector includes eighteen terminals. When sorting, the first terminal 4 of one second rubber core 3 is arranged on the leftmost side, and the first terminal 4 of the other second rubber core 3 is arranged on the rightmost side. All terminals on the two second rubber cores 3 are distributed at equal distances in the horizontal direction, and are staggered in the vertical direction. When the connector is plugged in, as the male connection part, the first terminal 4 with a longer length can contact with another connector in advance, which effectively plays a good grounding role, and then ensures that the signal of the second terminal 5 inserted later will not be lost after the connection, thereby improving the stability of the entire connector plugging.

The first terminal 4 and the second terminal 5 are provided with a protruding clamping portion 15 encapsulated inside the second rubber core 3 in the middle part. The second rubber core 3 is fixed at the middle part of the first terminal 4 and the second terminal 5, and adopts an encapsulation method. At the position where the first terminal 3 and the second terminal 4 are encapsulated in the second rubber core 3, a protruding anti-slip clamping portion 15 is provided. The clamping portion 15 has a flat structure, which effectively prevents all terminals from moving or rotating.

A protrusion 12 is provided on the side of the first rubber core 2 away from the card slot 9, and a through groove 13 is provided at the position where the first rubber core 2 inserts the first terminal 4 and the second terminal 5, which is connected to the surface of the protrusion 12. After the second rubber core 3 is assembled, one end of the first terminal 4 and the second terminal 5 must pass through the second rubber core 3 and the first rubber core 2 at the same time to extend to the end of the shell 1 with a smaller opening to form a male connection, and a spiral structure is provided at the end of the first terminal 4 and the second terminal 5. At the same time, when the first terminal 4 and the second terminal 5 are inserted and fixed, a protrusion 12 is provided on the side of the first rubber core 2 away from the card slot 9, and a through groove 13 for a single terminal to pass through is provided at the position where the first rubber core 2 inserts the first terminal 4 and the second terminal 5, and the opening of the through groove 13 extends from the surface of the protrusion 12.

The inner wall of the end with the smaller opening of the housing 1 is provided with at least two inwardly protruding connection limit portions 6, which play a fixing role when the male connector is connected to the corresponding component.

Compared with the traditional technology, the present technical solution assembles the first terminal 4 and the second terminal 5 fixed inside the shell 1 through the continuously detachable first rubber core 2 and the second rubber core 3, which reduces the difficulty of terminal assembly and facilitates the later maintenance of the terminals. At the same time, the length of the first terminal 4 is set to be longer than the second terminal 5. When the male connector is plugged in, the first terminal 4 first contacts to form a grounding effect, which effectively prevents signal loss or signal instability when the second terminal is plugged in, thereby improving the stability of the entire male connector.

It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, so it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
