Description

Plug connector

Technical Field

The utility model relates to the field of connectors, in particular to a plug connector.

Background

A plug connector is a commonly used electronic component, also called a plug connector, which is a device for transmitting power and signals in an electrical circuit, commonly used for connecting and securing a joint of wires.

The existing connector is to insert the plastic boss of the plastic shell into the clamping groove of the metal shell. The side surface of the plastic boss is a smooth surface, and the plastic boss is fixed in the clamping groove by means of interference fit. If the width of the plastic boss is slightly smaller in the manufacturing process, the plastic boss is insufficient and easy to fall off, if the width is larger, the plastic boss cannot be inserted into the clamping groove, so that the manufacturing precision requirement of the connector is higher, the connector is connected only through interference fit, no specific fixing and clamping structure clamps and fixes the electric wire, when the connected electric wire is pulled or rocked, the electric wire is easy to break away from or fall off from the plug connector, or the electric wire is unstable due to loosening, so that the electric wire is easy to short-circuit, and normal use is affected.

Disclosure of Invention

In order to overcome the defects of the prior art, the utility model provides the plug connector, which can effectively solve the technical problems of unstable connection of wires caused by the fact that the existing plug connector is not strong in connection stability and poor in fixity and the wires are easily separated from the plug connector and fall off or loose.

The technical scheme adopted for solving the technical problems is as follows: the utility model provides a plug connector, includes the casing, the inside of casing is provided with the connecting channel that switches on, the inside of casing is provided with the block portion, the top of block portion is provided with square groove, the inside of block portion is provided with square mouth, the fixed shell fragment that is provided with the symmetry of inner wall of casing, the inside of casing is provided with the grafting portion, the fixed a plurality of fixed strips that are provided with the slope decurrent in bottom of grafting portion.

Further, the fixing strips are distributed at equal intervals.

Further, the fixing strip is made of copper materials, and the width of the fixing strip is 0.2-0.4cm.

Further, two connecting columns are fixedly arranged at the bottom of the shell, the two connecting columns are symmetrically distributed, a plurality of positioning columns are fixedly arranged at the bottom of the shell, and the positioning columns are parallel to the connecting columns.

Further, the length of the connecting column is greater than the length of the positioning column.

Compared with the prior art, the utility model has the beneficial effects that: according to the plug connector, the clamping part, the plug part, the elastic piece and the fixing strip are arranged to be matched, so that the plug effect of the electric wire can be well realized, the electric wire is firmly connected, the stability of the electric wire is greatly improved, the connection stability is high, and the unstable connection of the electric wire due to loosening, falling or loosening during use can be prevented.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

As shown in fig. 1 and 2, a plug connector comprises a housing 1, a conductive connecting channel is arranged in the housing 1, a clamping portion 3 is arranged in the housing 1, a square groove 4 is formed in the top of the clamping portion 3, a square opening 8 is formed in the clamping portion 3, symmetrical elastic sheets 6 are fixedly arranged on the inner wall of the housing 1, a plug portion 7 is arranged in the housing 1, and a plurality of fixing strips 2 which are inclined downwards are fixedly arranged at the bottom of the plug portion 7.

The fixed strip 2 equally spaced arrangement distributes, fixed strip 2 comprises copper material, the width of fixed strip 2 is at 0.3cm, the fixed two spliced poles 9 that are provided with in bottom of casing 1, two spliced poles 9 are symmetrical distribution, the fixed a plurality of reference columns 10 that are provided with in bottom of casing 1, a plurality of reference columns 10 are parallel to each other with spliced pole 9, the length of spliced pole 9 is greater than the length of reference column 10, through setting up the cooperation of block portion 3, grafting portion 7, shell fragment 6 and fixed strip 2, can realize the grafting effect of electric wire well, improves its stability greatly, and connection stability is strong, can prevent that the electric wire from leading to connecting unstable because pine takes off and become flexible during the use, and electric wire inserts the inside of square groove 4, and shell fragment 6 and fixed strip 2 have elasticity, and when the electric wire stretches into, can be stable with the electric wire centre gripping, avoid the electric wire to be pulled out at will, square mouth 8 bottom the block portion 3 also has fixed effect, and the inside that the joint on the electric wire can be inserted to square mouth 8 realizes fixed cooperation.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
