Problems solved by technology

[0005] However, in the actual operation process, flying burrs (burrs), indentation deviation after cold pressing, terminal bending, wire breakage, wire shedding, and poor appearance of core wires and plastic wires in the crimping area after crimping often occur. Hidden dangers, which seriously affect the contact resistance of terminals during the operation of electrical devices
The main reason for the quality defect of cold pressing: there is no limit device for the position of the cable

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0028] The present invention provides a terminal crimping device, including a crimping pliers, the crimping pliers including an upper mold and a lower mold capable of fixing a terminal insert and a cable respectively, and a cable positioning device 1 is fixed on the crimping pliers.

[0029] In the embodiment provided by the present invention, the existing crimping tool is mainly improved by adding a cable positioning device to realize a terminal crimping device capable of positioning the cable. In this embodiment, the crimping tool can adopt the prior art For example, take the crimping tool used in the crimping process of the F-type crimping film crimping open terminal as an example. Other types of crimping tools can be adapted according to the specific structure, such as HARTING 09990000620 type crimping tools. The pressure clamp structure is the pri...

Abstract

The invention provides a terminal pressing device which comprises a pressing tongue. The pressing tongue comprises an upper mold and a lower mold which can respectively fix a terminal insert and a cable. The terminal pressing device is characterized in that a cable fixing device is fixed on the pressing tongue. The invention further provides a terminal pressing method in which the terminal pressing device is utilized. The terminal pressing device and the terminal pressing method can realize fixation of a cable placement position, thereby increasing terminal pressing success rate.

Description

Technical field [0001] The invention relates to a terminal crimping device, in particular to a terminal crimping device and a terminal crimping method capable of positioning the insertion length of a cable. Background technique [0002] During the construction, repair work and line operation of existing trains of 200-500 km EMUs, it was found that some wiring terminals had defects of varying degrees. Although most of the defects would not directly affect the performance of the vehicles, long-term existence would be a hidden danger. It has become an inertial problem that needs to be solved urgently, especially for the electrical work wiring of the real-time axle temperature detection system of the CRH2 EMU, which requires high terminal contact resistance for electrical equipment in harsh operating environments, but it is extremely easy to locate the cable due to inaccurate positioning. The cable insulation layer is mixed into the crimping area, or the exposed conductor brush is to...
