Specific embodiment

It is carried out below with reference to technical effect of the embodiment and attached drawing to the design of the utility model, specific structure and generation Clear, complete description, to be completely understood by the purpose of this utility model, scheme and effect.It should be noted that not conflicting In the case where, the features in the embodiments and the embodiments of the present application can be combined with each other.

It should be noted that unless otherwise specified, when a certain feature referred to as " fixation ", " connection " are in another feature, It can directly fix, be connected to another feature, and can also fix, be connected to another feature indirectly.In addition, this The descriptions such as upper and lower, left and right used in utility model are only the phase relative to each component part of the utility model in attached drawing For mutual positional relationship.

In addition, unless otherwise defined, the technology of all technical and scientific terms used herein and the art The normally understood meaning of personnel is identical.Term used in the description is intended merely to description specific embodiment herein, without It is to limit the utility model.Term " and or " used herein includes appointing for one or more relevant listed items The combination of meaning.

Referring to Fig. 5, the connector of the present embodiment includes terminal 1 and shell 2, and accommodating hole 21, terminal are provided in shell 2 1 is plugged in accommodating hole 21, and shell 2 is made of insulating material, and terminal 1 is made of conductive metal material, 1 He of terminal Shell 2 needs energy simple and stable after needing separately manufactured, the quick and effective requirement based on installation, terminal 1 to be plugged on accommodating hole 21 Ground is fixed.

Referring to figs. 1 to Fig. 3, for the function that realization 1 opposite shell 2 of terminal is quickly and effectively fixed, terminal 1 includes fixation First 11 and elastic slice 12, fixing head 11 and accommodating hole 21 are interference fitted, specifically, fixing head 11 includes backboard 111 and respectively With the side plate 111 of the both ends integrally connected of backboard 112, the U-shaped profile of fixing head 11, side plate 111 far from backboard 112 one End is greater than accommodating hole 21 in the width of corresponding direction at a distance from the first face 1121 of backboard 112, and terminal 1 is plugged on outer as a result, After in the accommodating hole 21 of shell 2, fixing head 11 is connected in accommodating hole 21, is realized simply, without effective fixation of operation bidirectional.

It referring to figure 6 and figure 7, is not crooked, the first face of backboard 112 after being plugged on terminal 1 in the accommodating hole 21 of shell 2 1121 inner walls 212 corresponding with accommodating hole 21 fit closely, by the face contact in the first face 1121 and inner wall 212, so that Terminal 1 be plugged on during accommodating hole 21 to being effectively directed at constraint, until terminal 1 is completely into accommodating hole 21, Gu Fixed position accurate in one direction, will not tilt, in the present embodiment, the first face 1121 is disposed as putting down with inner wall 212 Face may be alternatively provided as the close arc surface of curvature in other embodiments.

It referring to Fig.1, is the connector and the function removably fixed of plug connector of realizing the present embodiment, two blocks of side plates 111 It is provided with wire rod card slot 1112, along longitudinal direction to make fixing head 11 or the shell 2 cooperated with fixing head 11 after patching plug connector Will not be squeezed rupture, and at least one piece of the half block side plate of 1112 two sides of wire rod card slot and the inner wall of accommodating hole 21 have gap, Thus it may make the half block side plate of 1112 two sides of wire rod card slot with outward space after being squeezed, in the present embodiment, There is gap to be provided with gap for the half block side plate of 1112 two sides of wire rod card slot and the inner wall of accommodating hole 21, specifically, side plate 111 It is provided with the first short slot 1113 with the junction of backboard 112, side plate 111 is provided with the second short slot far from one end of backboard 112 1111, as a result, when in plug connector insertion connector, half side plate of 1112 two sides of wire rod card slot is squeezed deformation, due to setting In respect of the gap of deformation, terminal 1 or shell 2 can't the deformation fracture by excessive compression, it is good to patch quality.

Referring to Fig. 4 and Fig. 5, to prevent two blocks of side plates 111 of terminal 1 lean-in after one end of opening is by external force Tiltedly, accommodating hole 21 is provided with key shaped projection 211, key shaped projection 211 and two blocks of side plates 111 in one end that corresponding side plate 111 is open Opposite side fitting, key shaped projection 211 plays the role of support positioning.

In addition, accommodating hole 21 is settable multiple, thus corresponding terminal 1 can also be accommodated multiple, thus be can be improved and patched effect Rate.

It is to be illustrated to the preferable implementation of the utility model, but the invention is not limited to the reality above Example is applied, those skilled in the art can also make various equivalent variations without departing from the spirit of the present invention Or replacement, these equivalent deformations or replacement are all included in the scope defined by the claims of the present application.
