Abstract

The utility model belongs to the technical field of the connector and specifically relates to prevent draw-in connector. The connector comprises a shell, terminals and support legs, wherein plastic parts of the terminals are fixed in the shell, the support legs are arranged at the bottom end of the shell, the two sides of the shell are provided with tightly-pushing elastic pieces, the two sides of the shell are provided with inner buckles, a U-shaped clamping groove is formed in a back plate of the shell, and a convex block on the plastic parts of the terminals is arranged in the U-shaped clamping groove. The utility model discloses a U-shaped draw-in groove comes the position of fixed position terminal in the shell, avoids the terminal to rock in the shell. The clamping terminal is directly locked through the inner buckle, so that the riveting process is omitted, and the problem that the supporting legs shrink inwards due to riveting is avoided.

Description

Anti-retraction connector

Technical Field

The utility model belongs to the technical field of the connector and specifically relates to prevent draw-in connector.

Background

Electrical connectors, also commonly referred to as circuit connectors, bridge two conductors in a circuit so that current or signals can flow from one conductor to the conductor means of the other conductor. However, in the process of combining the housing and the terminal of the conventional connector, the terminal and the housing need to be riveted together, which not only easily causes the position of the terminal to shift, but also easily causes the housing legs to retract during riveting.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is: in order to solve the technical problem described in the background art, the utility model provides an anti-retraction connector. The position of the terminal in the shell is positioned through the U-shaped clamping groove, and the terminal is prevented from shaking in the shell. The clamping terminal is directly locked through the inner buckle, so that the riveting process is omitted, and the problem that the supporting legs shrink inwards due to riveting is avoided.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a prevent formula connector that contracts in, includes shell, terminal, stabilizer blade, and the working of plastics of terminal is fixed in the shell, and the shell bottom is equipped with the stabilizer blade, the shell both sides are equipped with the tight shell fragment in top, and the shell both sides are equipped with interior knot, are equipped with the U-shaped draw-in groove on the backplate of shell, and the lug on the terminal working of plastics is arranged in the U-shaped draw-in groove.

Specifically, the inner buckle is positioned in an opening at the side end of the shell, the head end of the inner buckle inclines towards the inside of the shell, and the tail end of the head end of the inner buckle is fixed on the shell.

Specifically, the bending pressure head of the jacking elastic sheet faces the support leg, the tail end of the jacking elastic sheet faces the jack of the shell, and the tail end of the jacking elastic sheet is fixed on the shell.

The utility model has the advantages that: the utility model provides a prevent formula connector that contracts inwards. The position of the terminal in the shell is positioned through the U-shaped clamping groove, and the terminal is prevented from shaking in the shell. The clamping terminal is directly locked through the inner buckle, so that the riveting process is omitted, and the problem that the supporting legs shrink inwards due to riveting is avoided.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a schematic structural diagram of the present invention;

in the figure, 1, a shell, 2, a terminal, 3, a jacking elastic sheet, 4, an inner buckle, 6, a U-shaped clamping groove and 7, a supporting leg are arranged.

Detailed Description

The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Fig. 1 is a schematic structural diagram of the present invention.

As shown in the attached drawing 1, the anti-retraction connector comprises a shell 1, a terminal 2 and support legs 7, wherein a plastic piece of the terminal 2 is fixed in the shell 1, the support legs 7 are arranged at the bottom end of the shell 1, two sides of the shell 1 are provided with tightly-pushing elastic pieces 3, two sides of the shell 1 are provided with inner buckles 4, a U-shaped clamping groove 6 is arranged on a back plate of the shell 1, and a convex block on the plastic piece of the terminal 2 is arranged in the U-shaped clamping groove 6. The inner buckle 4 is positioned in an opening at the side end of the shell 1, the head end of the inner buckle 4 inclines towards the inside of the shell 1, and the tail end of the head end of the inner buckle 4 is fixed on the shell 1. The bending pressure head of the jacking elastic sheet 3 faces the support leg 7, the tail end of the jacking elastic sheet 3 faces the jack of the shell 1, and the tail end of the jacking elastic sheet 3 is fixed on the shell 1.

When will connect the combination together with housing 1 and terminal 2 plug, insert the working of plastics of terminal 2 from housing 1 bottom, put into U-shaped draw-in groove 6 of housing 1 up to the lug of the working of plastics of terminal 2, just so can avoid terminal 2 to rock in housing 1. When the terminal is inserted, the inner buckles 4 (spring pieces) on the two sides can be sprung into the clamping grooves on the two sides of the terminal 2, so that the terminal 2 is clamped with the shell. Therefore, the housing 1 and the terminal are fixed without riveting, and the problem of inward shrinkage of the support legs 7 caused by riveting two sides of the housing 1 is avoided.

The bending pressure head of the jacking elastic sheet of the existing connector faces towards the jack, so when a plug is inserted into the connector, if the angle of the bending pressure head is too inward inclined, a roll PIN can be generated. And the tight shell fragment 3 in top of this application the pressure head of bending down, and the dog-ear of the tight shell fragment 3 in top of bending the pressure head inwards, consequently when external plug inserts, can not rolled up PIN when pushing away the pressure head of bending.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
