Card line plate, presses cable and is fixed in cable clamping interface, and the width M of card line plate is greater than the minimum widith L of card line entrance.
Tagblock of the present invention is integrated manufacture, closes up completely different from two panels of the prior art, and obviously, integrally manufactured intensity is obviously better than the intensity that two panels is closed up, under the prerequisite of same intensity, integrally manufactured material will significantly than two panels close up few.
The shape of cable clamping interface can have multiple, or the combination of various shape, shape due to cable is circular, in cable clamping interface shape, circle is preferred, consider that card line plate will compress cable, the shape of pressing section can be rectangle or other shape, can consider combination that is circular and rectangle on the whole.
The through hole of tagblock is fixed by screw, bolt and is electrically connected on other binding post of power equipment.
The area of the cable that described cable clamping interface, described card line plate surround is less than the area of tagblock dispatch from foreign news agency cable.
Press cable and can reduce contact resistance, but cable is twisted together by many single lines, between must have space, in extrusion process, need to reduce this space, space is fewer, and reliability is higher, and contact resistance is less, and the life-span is longer.
Integrally manufactured tagblock and the cable of compression form rigid structure, can not be out of shape, and contact resistance can not become large along with the increase of time.
The thickness of card line plate, is as the criterion can not be out of shape after compressing cable.
One of preferably, described card line entrance is rectangular or tubaeform.Cable clamping interface near described card line entrance is provided with plane.Utilize this plane, card line plate can seal cable more securely.
R angle is had between described card line entrance and described plane.Utilize this R angle, card line plate easily inserts in cable clamping interface.
One of preferably, described cable clamping interface is C font.Program material is comparatively economized.
A processing method for cable connecting terminal, comprises the steps:
A. process described tagblock, form described through hole and described cable clamping interface, the card line entrance minimum widith L meeting cable clamping interface is less than the Breadth Maximum D of cable clamping interface;
B. described cable is flattened to inserting cable clamping interface, the width M of described card line plate is bent to and is less than card line entrance;
C. card line plate is close to cable, with briquetting extruding card line plate and cable, cable is extruded aftercrimp, and card line plate is stuck in cable clamping interface after stretching.
In described step B, by cable flatten comprise, in advance with instrument flatten or round electric cabled yarn by being crushed time tubaeform.Because briquetting has two pieces, can extrude simultaneously or first extrude a piece wherein, then extrude other one piece.
In described step C, briquetting is arranged on punch press, press or Manual hydraulic grip.
The present invention has that structure is simple, cost is low, easy to process, contact resistance is little, electric performance stablity, non-maintaining, the beneficial effect of saving material.
