Embodiment

Below in conjunction with accompanying drawing, describe embodiment of the present utility model in detail.

Be illustrated in figure 1 the schematic diagram of a kind of specific constructive form of the utility model locking connector, as can be seen from the figure the utility model locking connector mainly comprises: connector 1, linking arm 2 and external connection portion 3, wherein, the left side of linking arm 2 is provided with two connectors 1, these two connectors 1 towards identical and laid out in parallel, external connection portion 3 is arranged on the right side of linking arm 2, and connector 1 is for stube cable, and external connection portion 3 is for connecting power equipment.The connector 1 of this tight lock connector can be processed into one or more according to actual needs, and regardless of quantity, its form, principle are identical, and the large I of model differs.

Connector 1 is shown in Fig. 3 primarily of inner sleeve 9() and outer cap 4 form, inner sleeve 9 is arranged to tubular structure and right-hand member is connected on linking arm 2, on the tube wall of its right-hand member, external screw thread 6 is provided with in inner sleeve 9, outer cap 4 is arranged to be set on the tubular structure outside inner sleeve 9, the right-hand member of outer cap 4 is provided with force section 5, force section 5 is hex nut in the present embodiment, inner sleeve 9 is threaded with outer cap 4, arrange a screw 7 in the radial direction of connector 1, screw 7 is by inner sleeve 9 and outer cap 4 and fix diametrically.

External connection portion 3 is the platy structure with connecting hole 8, the contact area that whole product and power equipment are installed when being connected is larger, when electric current is by this product and power equipment, its resistance value is less, temperature rise is lower, current stability is better, namely decreases the electric energy loss in electric current course of conveying.

External connection portion 3 is greater than 0 ° with the axis angle of connector 1 and is less than or equal to 90 ° as shown in Figure 2.Can provide multiple setting angle like this, make the assembling of locking connector and power equipment more flexible, applicability is stronger.

Inner sleeve 9, external connection portion 3 make one with linking arm 2 as shown in Figure 3.Cable is entered by the opening of inner sleeve 9 left end, has fine thread (not shown) at opening inwall, increasing friction force, fastening grip, thus also enhances this connector and cable and install and bear pulling force when being connected; Inner sleeve 9 appearance has inner sleeve first step 9a, inner sleeve slope 9b, inner sleeve second step 9c; By inner sleeve 9 left end opening to the tube wall of the external screw thread 6 of inner sleeve 9 right-hand member there being at least plural machinery seam 10, the present embodiment is preferably four road machinery seams 10, increase the systolic pressure of inner sleeve 9, increase the contact area of connector 1 and cable, namely better execution concurrence has waved the science of expansion bolt principle simultaneously.

The tube wall of inner sleeve 9 is as shown in Figure 4 provided with four roads machinery seams 10, this four roads machinery seam 10 is spacedly distributed around axis.

The tube wall of inner sleeve 9 is as shown in Figure 5 provided with twice machinery seam 10, this four roads machinery seam 10 is spacedly distributed around axis.

Outer cap 4 is bucket shape tubulose as shown in Figure 6, the inner tubal wall of outer cap 4 is arranged outer cap first step 4a, outer cap second step 4b, outer cap the 3rd step 4c.Three interior step 4a, 4b, 4c of outer cap 4 respectively with two step 9a, 9b Matching installations of inner sleeve, be multi-stage stairs and tightly lock principle.Multi-stage stairs tightly locks principle makes that larger, the fastening grip of the contact area of whole product and cable is stronger, mechanical stability is better, when causing electric current by this product and cable, temperature rise is lower, resistance is less, current stability is better, namely decreases the electric energy loss in power equipment running.

Radial direction is provided with tapped through hole to the tube wall of outer cap 4, and screw 7 screw thread is arranged in this through hole, and after screw 7 is installed, its afterbody is squeezed in inner sleeve 9.Utilize the radial screw 7 arranged outer cap 4 and inner sleeve 9 to be fixed, make outer cap 4 and inner sleeve 9 in the axial direction relative movement can not occur, thus it is loosening to avoid cable to connect.Screw 7 is the screw of existing various types, as: hex head screw, square head screw, fillister head screw, source screw, Phillips-type screw etc.

The installation method of this tight lock connector and cable: inserted from inner sleeve 9 left end opening through after outer cap 4 by cable, then use spanner clamping force section 5, tightens outer cap 4 with inner sleeve 9, tightens screw 7.

Be illustrated in figure 7 the second connected mode of inner sleeve 9 and outer cap 4, compared with Fig. 6, its version is substantially identical, and difference is: on the outer circumference surface of inner sleeve 9, be provided with blind hole, and after screw 7 is installed, its afterbody inserts blind hole.This blind hole can be internal thread hole, also can be unthreaded hole; When blind hole is internal thread hole, the through hole on outer cap 4 can be arranged to unthreaded hole.

When rigging screw 7, the through hole on outer cap 4 and the blind hole in inner sleeve 9 can be aligned rear tightening screw 7, or cap 4 and inner sleeve 9 offer through hole and blind hole after assembling again outside.

Above-mentioned example is just for illustration of the utility model, and execution mode of the present utility model is not limited to these examples, and what those skilled in the art made meets the various embodiments of the utility model thought all within protection range of the present utility model.
