Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

As shown in Figure 1, present embodiments providing a kind of fixing clasp for fixed connection device and cable, connector 1 is wrapped The internal shell for being equipped with a cavity is included, inner core (not shown) is equipped in shell, the tail end of shell is set to be connect there are two columnar Terminal 11, binding post 11 are equipped with current supply cable 2 and put in the wiring hole connecting in shell and with inner core, and fixing clasp 4 is fastened in wiring The periphery of 2 junction of column 11 and cable.

In conjunction with Fig. 2, fixing clasp 4 includes two panels in arcuation and the body of clasp that joins end to end circlewise, and body of clasp has the One end and second end, the first end of body of clasp and the second end of another body of clasp are interlocked, the second end of body of clasp and another card The first end of ring body is interlocked, and two body of clasp cooperations apply radial force inwardly to the binding post 11 and cable 2 mutually plugged together, So that binding post 11 is tightened cable 2, improves the good airproof performance between binding post 11 and cable 2, can effectively prevent grease, dust etc. Into in connector 1, reduce the generation of failure.

Body of clasp includes the upper snap ring 41 covered on binding post 11 and covers the lower snap ring 42 on cable 2,41 He of upper snap ring Lower snap ring 42 is an integral molding structure, and the outer diameter of lower snap ring 42 is less than the outer diameter of upper snap ring 41 and the outer diameter phase with binding post 11 Together.The first end of body of clasp is equipped with the first fastener 411 positioned at upper snap ring 41 and the first fastener 422 on lower snap ring 42, The second end of body of clasp is equipped with the second fastener 421 positioned at the second fastener 412 of upper snap ring 41 and positioned at lower snap ring 42.First Fastener 411 and the second fastener 412 of another body of clasp second end are interlocked, the first fastener 422 and another body of clasp second end Second fastener 421 is interlocked, and makes the radial force of two body of clasp inwardly to binding post 11 and cable 2 application mutually plugged together.It is connected Two upper snap rings 41 between radial direction by the application of fastening pairs of posts 11 of the first fastener 411 and the second fastener 412 inwardly Power, between the lower snap ring 42 of connected two by the fastening of the second fastener 421 and the first fastener 422 to the application of cable 2 inwardly Radial force entangles two snap ring physical efficiencys by binding post 11 and cable 2 firm, and compactness is more preferable.

First fastener 411 is identical as the structure of the second fastener 421 and is convex block, the first fastener 422 and the second fastener 412 Structure it is also identical and be U-shaped snap arm, when the first card body and the second button are interlocked, U-shaped snap arm need to only be turned to set In the side of convex block, this structure for snapping together two body of clasp is simple, easy to operate, and fastness is high.

The first card slot 43, the extending direction and binding post 11 of the first card slot 43 and pulling out for cable 2 are offered in upper snap ring 41 Direction interpolation is identical, and the notch of the first card slot 43 is located at the one end of upper snap ring 41 far from lower snap ring 42, the lateral wall of binding post 11 On integrally formed with the first positioning strip 111 corresponding with 43 position of the first card slot.When upper snap ring 41 is covered completely on binding post 11 When, the first positioning strip 111 keeps off the slot bottom in the first card slot 43 to prevent body of clasp to be detached from binding post 11, to make card The mounting structure fastness of ring 41 is higher.

The second card slot 44 is also provided in upper snap ring 41, the second card slot 44 prolongs along binding post 11 and the direction that plugs together of cable 2 Stretch and notch direction be contrary with the notch of the first card slot 43, on the lateral wall of binding post 11 integrally formed with the second card slot Corresponding second positioning strip 112 in 44 positions, the second positioning strip 112 and the cooperation of the second card slot 44 can limit fixing clasp 4 around its axis To rotating, the compactness between fixing clasp 4 and binding post 11 is further improved.

There are two second card slots 44 and is located at the two sides of the first card slot 43, and this set can make body of clasp in the first card Structural strength near slot 43 is lower, relatively easy bending deformation, when the first positioning strip 111 is imported in the first card slot 43, Keep body of clasp not easily damaged.

As shown in connection with fig. 3, the part that cable 2 stretches out outside binding post 11 is arranged between lower snap ring 42 and cable 2 Bellows 3, bellows 3 are equipped with wave groove 31, and the internal perisporium of lower snap ring 42 is integrally formed with the arc put in wave groove 31 Protrusion 423, bellows 3 is arranged on the outside of cable 2 can protect cable 2, while also facilitating and being bent to cable 2.

The inner sidewall of wire column, which is arranged with, puts in waterproof grommet 5 on the outside of wiring hole, waterproof grommet 5 positioned at cable 2 Also pad is equipped with crimp rings 6 between cable 2, and the setting of waterproof grommet 5 and crimp rings 6 further makes binding post 11 and cable 2 Between airtightness it is more preferable.

The course of work and principle: after the wiring hole that cable 2 injects binding post 11, first two panels body of clasp is covered in wiring The periphery of column 11 and 2 junction of cable, and make the first positioning strip 111 in 43 pairs of posts 11 of the first card slot on body of clasp, First positioning strip 111 plugs together the limitation realized on direction to body of clasp freedom degree binding post 11 and cable 2；Later by snap ring The first end of body successively fastens circlewise from beginning to end with the second end for the body of clasp that is connected, and to the binding post 11 and electricity mutually plugged together Cable 2 applies radial force inwardly, so that binding post 11 and cable 2 be made to be tightly coupled together, and then makes between shell and cable 2 The phenomenon that being less prone to loosening improves the reliability of connector 1.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
