Description
Technical field
The utility model relates to conductor jointer, particularly relates to a kind of big current conductor jointer.
Background technology
As everyone knows, in the test link of research institute, laboratory and production system, often can run into the problem of high-current test, often need connecting and disconnecting big current wire repeatedly.Big current mentioned here refers to the electric current of peace up to a hundred to thousands of peace.In high-current test, connecting and disconnecting big current wire is very troublesome thing repeatedly, and this is not disposable fixed installation, it is desirable that high efficiency reliable provisional connecting and disconnecting.The connection of big current wire is different from general small area analysis wire, enough contacts area and certain contact must be had, otherwise will tie point be caused due to loose contact to generate heat, even can cannot meet the requirements of big current numerical value because contact resistance is large.
The connection of current big current wire uses line ear mostly, first by the line ear of two side pressures (or weldering) the upper corresponding size of big current wire, is then connected by two line ear bolts.Will use spanner during operation, nut will turn a lot of circle, in order to be compressed by two line ears, finally uses very energetically.Whole process wastes time and energy, and many times also wants two people to complete.Another drawback that line ear connects is that the external diameter of line ear is often much larger than the external diameter of big current wire, and normal wired ear cannot through the embarrassment of test product through wires hole.Now have to cut away line ear and first wire be passed test product through wires hole, row test more then press (or weldering) upper new line ear again on wire after.Also again to cut away line ear after having tested and just can take off test product.Its trouble degree is well imagined.
Utility model content

Fig. 1 is the overall structure schematic diagram of a kind of preferred embodiment of the utility model big current conductor jointer.
Fig. 2 is the structural representation of the male of the conductor jointer of big current shown in Fig. 1.
Fig. 3 is the structural representation of the female seat of the conductor jointer of big current shown in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1, shown in Fig. 2 and Fig. 3, the present embodiment provides a kind of big current conductor jointer 1, big current conductor jointer 1 comprises and is connected to male 11 on big current wire two terminations (not shown) and female seat 12, one end of male 11 is connected with a termination, the other end of male 11 is provided with cone 111 and short screw 112 successively, and the major diameter of thread of short screw 112 is less than the minimum outer diameter of cone 111, one end of female seat 12 is connected with another termination, the other end correspondence of female seat 12 is provided with the taper hole 121 suitable with cone 111 and the short screw 122 suitable with short screw 112.
In the present embodiment, as shown in Figure 1, Figure 2 and Figure 3, one end of male 11 is provided with the first bonding wire cavity 113, the internal diameter of the first bonding wire cavity 113 and the external diameter of termination suitable, and the sidewall of the first bonding wire cavity 113 is provided with one first tin input hole 114, one end of male 11 and a termination are welded to connect.One end of female seat 12 is provided with the second bonding wire cavity 123 being communicated with short screw 122, the internal diameter of the second bonding wire cavity 123 and the external diameter of termination suitable, and the second bonding wire cavity 123 is provided with rounded tabs 125 with the joint of short screw 122, the sidewall of the second bonding wire cavity 123 is provided with one second tin input hole 124, and one end of female seat 12 and another termination are welded to connect.The tapering of cone 111 and the tapering of taper hole 121 are all 1:10, and the inner surface of the outer surface of cone 111 and taper hole 121 is all polished bright and clean, combine closely both when making cone 111 insert taper hole 121, during connection, only the short screw 112 of cone 111 front end can need be made cone 111 and taper hole 121 tight fit by short screw 122 1 circle screwed in bottom taper hole 121, during practical operation, the number of turns of screw-in is neither greater than 1.5 circles, is not also less than 0.8 circle.As shown in Figure 1, so just, can guarantee under cone 111 with the close-fitting condition of taper hole 112, all leave the gap of about 2mm in the front-end and back-end of cone 111, namely the bottom surface of taper hole 121 can not be withstood in cone 111 front end, and the step of cone 111 rear end can not contact with the outer face of taper hole 121.
As shown in Figure 1, the entirety of big current conductor jointer 1 is circle club shaped structure, and the maximum outside diameter of big current conductor jointer 1 equals the external diameter of big current wire (not shown).So, this big current conductor jointer 1 just can be avoided occurring through the problem of test product cable-through hole, to make it the cable-through hole that can be easily threaded through test product, thus can be applied in various occasion, extremely easy to use.
The big current conductor jointer that the present embodiment provides, it comprises and is connected to male on big current wire two terminations and female seat, and between male and female seat by cone and taper hole suitable, because the contact area of tapering will much larger than the contact area of connecting ring, as long as thus there is an axial compressive force between cone and taper hole, just can produce very large contact on the conical surface, and the axial compressive force that can provide between cone and taper hole the short screw of cone front end is provided in the short screw bottom taper hole, thus ensure that the Contact of cone and taper hole is good, and just can complete connection owing to only the short screw of cone front end need be screwed in the short screw bottom taper hole, it is simple efficient apparent that it operates.Thus, this big current conductor jointer has that contact area is very large, contact point pressure is large, contact resistance is little, connect the advantages such as safe and reliable, and it is simple to operate, connect, disconnect all very convenient, one people gets final product easy manipulation, very high operating efficiency can be ensured, be specially adapted to the occasion needing high frequency break-make.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
