Detailed Description

Embodiments of the present utility model are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model. In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "front", "upper surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the apparatus or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

Referring to fig. 1-3, an embodiment of the present utility model is provided: a combined terminal comprising a connection part 1 connected with a wire and a cannula 2 for male insertion; the connecting part 1 is in threaded fit with an external threaded column 22 arranged on the insertion tube 2 through an internal threaded hole 12; the inner wall surface of the insertion tube 2 is also provided with a plurality of inclined grooves 20, and the plurality of inclined grooves 20 are uniformly distributed on the inner wall surface of the insertion tube 2.

Because the cannula 2 is movably connected with the connecting part 1, the cannula 2 is easy and convenient to install and replace, meanwhile, the chute 20 on the inner wall surface of the cannula 2 can eliminate electric arcs generated in the moment that the male head is connected with the cannula 2 or separated, particularly, the outer wall surface of the chute 20 is contacted with the male head, and the inner wall surface of the chute 20 is far away from the male head, so that after the male head is inserted, a sufficient gap is reserved between the inner wall of the cannula 2 and the outer wall of the male head, and heat generated during the use of the device is conveniently discharged.

In addition, the threaded fit of the insertion tube 2 and the connecting part 1 is convenient to process, and the problem of inconvenient replacement between the guide and the insertion tube 2 can be solved by the simplest structure.

Further, since the cavity 21 is further provided in the interior of the insertion tube 2, and the cavity 21 is connected and communicated with the chute 20, when the male head is inserted, the cavity 21 can accommodate the end of the male head, so as to reduce the burning loss of the end and the burning loss of the insertion tube 2; secondly, the air flow exchange between the chute 20 and the cavity 21 is also convenient, so that burning loss or heat damage is reduced.

Further, since the end of the chute 20 away from the external thread post 22 completely penetrates the insertion tube 2, the external air flow can enter the insertion tube 2, and the hot air flow in the insertion tube 2 can flow out, so that the problem of the service life shortening of the terminal caused by heating can be reduced.

On the basis of the scheme, since the connecting part 1 comprises the sleeve 10 and the fixing part 13, and the sleeve 10 is communicated with the inside of the fixing part 13, the sleeve 10 can be covered outside the wire to prolong the length of the wire entering the inside of the connecting part 1, so that the connection strength with the wire is enhanced; secondly, the phenomenon of electric leakage occurring when the equipment is used can be reduced.

Further, since the fixing portion 13 is further provided with a screw hole 11 in the radial direction, and the screw hole 11 completely penetrates through the fixing portion 13, two bolts can be inserted from two ends of the screw hole 11, and the wire can be fixed on the connecting portion 1 along with tightening of the bolts, so that reliability of the wire after being connected with the connecting portion 1 can be ensured; meanwhile, when the bolts are loosened from the two ends of the screw holes 11, the lead can be pulled out from the fixing part 13, so that the lead and the connecting part 1 are convenient to assemble and disassemble. Based on the above, the device connecting part 1 and the lead wire and the connecting part 1 and the cannula 2 are detachable, and the assembly is convenient, so that the maintenance cost of the device in use is reduced.

Further, since the sleeve 10 is connected to the fixing portion 13 through the channel 14, and the inner diameter of the channel 14 is smaller than the inner diameter of the sleeve 10, the conductive portion of the wire can pass through the channel 14 and enter the fixing portion 13, and the insulating layer of the wire is accommodated by the sleeve 10. So that the conductive part of the wire can be prevented from being exposed.

In addition, in practical application, the connecting portion 1 may be made of an insulating material, and the outer wall surface of the cannula 2 is sprayed with the insulating material.

The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings, but the present utility model is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, and yet fall within the scope of the utility model.
