Description

A kind of crimp type 2M joints with signal pin plug

Technical field

The utility model belongs to technical field of communication equipment, and in particular to a kind of crimp type 2M with signal pin plug connects Head.

Background technology

With the development of power communication, the communication equipment of transformer station is gradually improved, in these communication apparatus, wherein number is matched somebody with somebody Rack plays vital effect, and the outside switching of business could be only realized by them.

During number is matched somebody with somebody, the quality of 2M joints is related to whether every business can normally transmit, and present 2M joints are all welderings Connect, but the space that 2M joints provide welding is very narrow, 2M joints are smaller, and the welding space that it is provided is bigger than electric soldering iron tip Not how many, scolding tin is not easy to place, and scolding tin has been truncated to put up and easily missed, and section long may occur short circuit.In welding Shi Bixu has the second people aside to help, and a people can not be completed task at all., it is necessary to look for power supply at the scene during welding, plug Electric iron is preheated, after preheating terminates, and a first hand takes one end of 2M joints, and another hand takes electric iron, the second people Steady data wire is grabbed with a hand, another hand is coordinated by scolding tin, because space is small, easily accidentally burn the second people's Hand, with certain danger；In addition, scolding tin, which belongs to, easily melts metal, in welding, unpleasant gas, this gas can be sent Body sucks lung by human body, can cause potentially hazardous to human body.And because 2M joints space is small, in welding easily number It is welded together according to the copper core of line and the joint shell of 2M data wires, cause short circuit, it is also possible to occur the problems of welded quality such as rosin joint, And be not easy to be found.

After the completion of 2M welds, during insertion number is matched somebody with somebody, screw is tightened, realizes that business circulates, but after operation a period of time, it is few Number 2M joints can loosen because of not prison welding, come off, and cause business obstructed, optical transmitter and receiver alarm.2M service includes administrative electricity The business such as words, dispatching automation, protection peace control, if the 2M tapes is administration telephone business, problem is not very big, if 2M Tape is relay protection business, and the business is 220kV line differential protections, and circuit, which breaks down, needs tripping operation, because 2M is logical Road is obstructed, and the circuit will not trip, and at this moment will occur the great power grid accidents such as circuit is burnt, transformer is damaged.In addition, existing 2M joints generally use ferroalloy, its toughness is small, and crushing is easy in crimping, and the joint being just welded generally requires weight New cut short makes again.

The patent of Application No. 201520662321.8 discloses a kind of 2M ends, and the end is from the inside to the outside successively For inner conducting layer, inner insulating layer, screen layer, outer jacket, crimping layer, the inner conducting layer is connected by cable end inner wire with 2M The contact pin of device is welded, and spends cylinder between the inner insulating layer and screen layer for the roller of 2M connectors, the screen layer is uniform Parcel roller flower cylinder, it is to crimp connection, the pyrocondensation that the crimping layer, which is covered between screen layer and crimping layer end and screen layer, Layer is socketed on the outside of 2M ends.Its preparation method is：Layer 5 now will be crimped and shrink wrap layer 6 is sleeved on one end of cable, then will The inner wire 1 of cable end is stripped out, and the inner wire 1 being stripped out is inserted in the contact pin 7 of 2M connectors, by 2M connectors Roller flower cylinder 8 be plugged between the inner insulating layer 2 of cable and screen layer 3, screen layer 3 is uniformly attached to the roller of connector and spend circle On post 8, crimping layer 5 is covered on screen layer 3, is then compressed with Crimping Pliers at the two ends of crimping layer 5, then welds inner wire 1 with the contact pins 7 of 2M connectors, after shrink wrap layer 6 is sleeved on the outside of end, make shrink wrap layer 6 and end tight using heat gun Contiguity is touched.End conduction property described in the utility model is good, and service life can reach more than 10 years.But above-mentioned 2M It is existing conventional 2M heads that end has 2M connectors used in problems with, one, above-mentioned 2M ends simultaneously, and this is special Profit is not significantly improved to its structure, and the contact pin space size of the 2M connectors determines the size for welding space, is Ensure that the inner wire of cable end is contacted well with contact pin, contact pin space is still very narrow and small（Accompanying drawing 1）, it is unfavorable for operation with seeing Examine, the problems such as still occurring rosin joint, sealing-off, and be difficult to be found by operator, therefore its background technology [0002] section is proposed " tending to cause the phenomenons such as end cored wire rosin joint, sealing-off, broken string in operation ", which does not have, obtains substantial solution.Its 2nd, with reference to accompanying drawing 1 it was determined that shrink wrap layer is enclosed on the outside of crimping layer in above-mentioned 2M ends, if crimping in practical operation Lamination connects loosely, then shrink wrap layer does not have effective fixed work then through heat effect retraction in the outside of crimping layer to 2M ends With.

Based on above mentioned problem, a kind of reliable and stable 2M joints of exploitation are needed badly, to solve the above-mentioned of existing 2M joints presence It is not enough.
