Description
Technical field
The utility model belongs to technical field of communication equipment, and in particular to a kind of modified 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 hand of people one takes one end of 2M joints, and another hand takes electric iron, and the second people uses
One hand grabs steady data wire, and another hand is coordinated by scolding tin, because space is small, easily accidentally burns the hand of the second people,
With certain danger；In addition, scolding tin, which belongs to, easily melts metal, in welding, unpleasant gas, this gas quilt can be sent
Human body sucks lung, human body can be caused potentially hazardous.And because 2M joints space is small, in welding easily data wire
Copper core and 2M data wires joint shell it is welded together, cause short circuit, it is also possible to the problems of welded quality such as rosin joint occur, and not
Easily it is 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.The patent of Application No. 201510540841.6 discloses a kind of 2M end systems
Make technique, comprise the following steps：(1) crimp sleeve and heat-shrinkable T bush are successively sleeved on to one end of 2M cables；(2) by cut cable
The inner wire in portion is stripped out from protective coverings of cable, inner insulating layer, ensures that protective coverings of cable is concordant with the end face of inner insulating layer
It is smooth and do not damage screen layer and inner wire；(3) inner wire being stripped out is inserted in the contact pin of 2M connectors, makes contact pin end
The step in portion is in contact with the inner insulating layer of cable；(4) by the rollers of 2M connectors flower cylinder be plugged on cable inner insulating layer and
Between screen layer, screen layer is set uniformly to be attached on the roller flower cylinder of connector, by crimp sleeve covering on the shielding layer, Ran Houyong
Crimping Pliers compresses at the both ends of crimp sleeve；(5) external terminal of 2M connectors is separated with the interior insulation of 2M connectors, keeps inserting
The step of pin and the interior insulation of cable and the interior insulation of 2M connectors contact with each other, and are then welded with scolding tin in contact pin and cable
Conductor；(6) welding is completed, and the interior insulation of the external terminal of 2M connectors and 2M connectors is plugged in together；Then will be by pyrocondensation
Sleeve is socketed in the junction of crimp sleeve and cable, pyrocondensation sleeve is tightened up in junction.Above-mentioned 2M manufacturing cable heads technique
Problems be present：First, the technique is（5）Just crimp sleeve is covered on the shielding layer and compressed before step welding, if
Pinpointed the problems before welding or in welding process, it is necessary to adjust or re-start making, because crimp sleeve has crimped fixation, just
It can to adjust or dismantle to become trouble, and waste crimp sleeve, reduce producing efficiency.Second, the technique is inserted using scolding tin welding
Pin and cable inner conductor, because the structure of contact pin limits, the problems such as easy rosin joint, broken string still be present using scolding tin welding, and
It is not easy to be found by operator.
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.
