Description

A kind of crimp type 2M joints

Technical field

The utility model belongs to technical field of communication equipment, and in particular to a kind of crimp type 2M joints.

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, section long to occur short circuit.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, and after preheating terminates, 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 burns the second people's Hand, there is 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, human body can be caused potentially hazardous.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 the problems of welded quality such as rosin joint occur, And it is 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, to be needed to trip, because 2M leads to Road is obstructed, and the circuit will not trip, and the great power grid accidents such as circuit burns, transformer damages at this moment will occur.It is in addition, existing 2M joint generally use ferroalloys, its toughness is small, crimping when be easy to crush, the joint being just welded generally require 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, uniform for the roller flower cylinder of 2M connectors, the screen layer between the inner insulating layer and screen layer 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 both 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 There is problems with end, 2M connectors used are existing conventional 2M heads in one, above-mentioned 2M ends, and this is special simultaneously Profit does not significantly improve to its structure, and the contact pin space size of the 2M connectors determines the size in welding space, is Ensure that the inner wire of cable end contacts well with contact pin, contact pin space is still very narrow and small（Accompanying drawing 1）, it is unfavorable for operation and sees Examine, the problems such as rosin joint, sealing-off still can occur, and be not easy to be found by operator, therefore Application No. 201520662321.8 is special Profit " tends to cause end cored wire rosin joint, sealing-off, broken string etc. existing what background technology [0002] section was proposed in operation As " do not obtain substantial solution.Secondly, with reference to accompanying drawing 1 it was determined that shrink wrap layer is enclosed on crimping in above-mentioned 2M ends The outside of layer, if crimping lamination connects loosely in practical operation, then shrink wrap layer is crimping the outside of layer to 2M through heat effect retraction End does not have effective fixation then.

Based on above mentioned problem, a kind of reliable and stable 2M joints of exploitation are needed badly, it is above-mentioned existing for existing 2M joints to solve Deficiency.
