The shrapnel is a flat body, the elastic arm and the fixed part are arranged in parallel up and down, and the rear ends are connected together in a U-shape placed horizontally.

There are two supporting feet at the lower side of the fixed part, and there are two front and rear slots correspondingly inside the shell, of which the rear slot is a semi-closed structure with a rear baffle, and the front slot is constructed on a horizontal rib , obtained by vertical sectioning; the rear side of the transverse rib is an inclined surface inclined backward.

The utility model is provided with pins at the front end of the fixed part of the shrapnel, and a supporting foot is provided on the lower side of the fixed part, and the pins are axially inserted into the jacks on the end of the rubber core, and the pins are provided with anti-retraction protrusions that are snapped into the plug hole, and the supporting legs are vertically inserted into the preset slots inside the casing; this structure well restricts the front, rear, left, right, and up and down directions of the fixed part, so as to ensure that there will be no misalignment of the fixed part when pressing, which also ensures that the spring The barb on the arm normally protrudes from the card position; it is easy to assemble, has a long service life, and improves the performance of the connector.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in accompanying drawings 1 to 8, the connector shrapnel assembly structure described in the present invention includes a rubber core 10, a shrapnel 20 and a shell 30, and a card platform 11 is formed on the edge of the rear end of the rubber core 10, and the card platform 11 snaps Connected to the slot 31 inside the front end of the housing 30 to form an axial connection; the elastic piece 20 has a barb 21 that can assist the connector to insert and prevent backlash. The barb 21 is arranged on an elastic arm 22, and the elastic arm 22 is connected to the elastic piece The fixed part 23. The elastic arm 22 protrudes from the back to the front, and there is just an axial flashing slot 12 on the rubber core 10 for the elastic arm 22 to protrude. It is used to assist the connector in positioning and prevent it from retreating; the elastic arm 22 is also provided with a pressing part 24, which is convenient for pressing and manipulating the barb 21, so as to realize unbuckle and pull out of the connector.

As shown in FIG. 2 , the elastic piece 20 is a flat body, the elastic arm 22 and the fixing portion 23 are arranged parallel to each other up and down, and the rear ends are connected together in a U-shape placed horizontally. There is a pin 25 at the front end of the fixed part 23 of the shrapnel, and a supporting pin 26 is provided on the lower side of the fixed part 23; hole 13, and the pin 25 is provided with an anti-retraction thorn 251 that is snapped into the socket 13, restricting the retreat of the fixed part 23, so that the shrapnel 20 is relatively immovable with the rubber core 10 in the axial direction, and at the same time, the pin 25 and the plug The hole 13 cooperates to relatively fix the front end of the fixed part of the elastic piece 20, preventing the front end of the fixed part from leaning forward and the rear end upturned when the elastic piece is pressed, and the stability is good.

The supporting feet 26 on the lower side of the fixing part 23 are vertically inserted into the preset slots 32 inside the housing 30, thereby further defining the left and right and up and down positions of the fixing part. As shown in Figures 7 and 8, in the present embodiment, there are two supporting feet 26 at the front and rear intervals on the lower side of the fixed part 23, and the inside of the housing 30 is correspondingly provided with two front and rear slots 32, and the width of the slot 32 is the same as that of the supporting feet 26. Matching thickness, good assembly effect. Among the two slots, the rear slot 32 is a semi-closed structure with a rear retaining surface, the rear retaining surface restricts the support feet 26 from retreating, and the front slot 32 is constructed on a transverse rib 33, which is obtained by vertical cutting, and the transverse rib 33 is just the rear wall of the draw-in groove 31, and the rear side of the transverse rib 33 is an inclined surface inclined backward, which is relatively lengthened to match the supporting foot 26, and the inclined surface has a tendency to lean forward, which can better support The card platform 11 of the top rubber core 10 has a good structure.

As shown in Figures 4 and 8, in this embodiment, a part of the front supporting foot 26 connected to the pin 25 protrudes forward from the slot 32 during assembly, and is inserted into the section extending from the lower side of the insertion hole 13 of the rubber core 10. In the hole, the connection between the fixed part of the shrapnel and the rubber core is increased, the structural strength of the connection is good, and it is not easy to deflect and dislocate.

The utility model optimizes the structural design, strengthens the assembly relationship between the fixed part 23 of the shrapnel, the rubber core 10 and the shell 30, and is more stable and less prone to misalignment. Connector performance.
