Embodiment 1

[0042] In order to solve the problem of cumbersome operation and long time-consuming when the heat-shrinkable tube in the prior art is used to weld the cable interface and cables of several pins, the present invention provides a pre-installed fixture 1 for cables and cable interfaces ,Such as figure 1 and figure 2 As shown, there are several passages 11 passing through the pre-installation fixture 1 , and the two ends of the passages 11 form two mouths 1101 and 1102 with the surface of the pre-installation fixture 1 respectively. Wherein, the two openings 1101 and 1102 of the channel 11 are respectively used for inserting cables and inserting corresponding pins of the cable interface.

[0043] The pre-installation jig 1 provided in this embodiment uses the partitions naturally formed between the channels 11 by the pre-installation jig 1 to replace the heat shrinkable tubes in the prior art, so as to realize the insulation and isolation of each welded part. When the pre-inst...

Embodiment 2

[0056] The welding method of the cable and the cable interface in the prior art has the technical defects of cumbersome operation steps and long time consumption. In view of the above technical defects, the present invention provides a welding method of the cable and the cable interface. The pre-installed fixture 1 provided in Embodiment 1; the cable includes several core wires 3; the cable interface 2 includes several pins 21, wherein the pins 21 are used for welding with the core wires 3; the number of core wires 3, pins The quantity of 21, the quantity of channel 11 are all equal; The welding method comprises the following steps:

[0057] 1. The pre-installation step is to set all the core wires 3 and all the pins in the pre-installation fixture 1, so that each pin 21 is arranged in a channel 11 opposite to a core wire 3; wherein, before the pre-installation step, The relative positions of all core wires 3, all pins 21 and pre-installed fixture 1 are as follows: image 3 s...

Embodiment 3

[0074] In order to provide a cable welding piece whose welding part is not easily damaged, the present invention provides a welding piece, such as Figure 5 As shown, it includes a cable interface 2, several core wires 3 and a pre-installed clamp 1;

[0075] The cable interface 2 includes several pins 21;

[0076] The pre-installation fixture 1 includes several passages 11 passing through the pre-installation fixture 1, and the two ends of the passage 11 respectively form two mouths 1101 and 1102 with the surface of the pre-installation fixture 1;

[0077] The number of core wires 3 is equal to the number of pins 21 and the number of channels 11;

[0078] Inside each channel 11, a core wire 3 and a pin 21 are fixed by welding.

[0079] The structure of the cable weldment provided by Example 3 is simple, and the insulation and isolation between multiple welding parts (the welding part of the core wire 3 and the pin 21) is realized by using the pre-installation fixture 1. The...

Abstract

The invention relates to the field of cable processing, and provides a method for welding a cable and a cable interface. The method comprises the following steps of: pre-assembling and fixing a plurality of core wires and a cable interface provided with a plurality of pins through a pre-assembling clamp, and then electrically connecting and fixing the core wires and the corresponding pins in a channel of the pre-assembling clamp in a hot soldering manner. According to the welding method, the butt joint accuracy of the pins and the core wires is greatly improved, the occurrence probability of short circuit between the core wires is reduced, and the labor intensity of operators can be relieved. The welding method is simple in operation step and short in consumed time, a foundation is provided for achieving automatic welding of the multiple pins and the corresponding core wires, and favorable conditions are created for improving the welding efficiency of the pins and the core wires. Besides, the pre-assembling clamp can effectively protect the welding parts of the pins and the core wires, so that the connection reliability of the pins and the core wires can be improved, and the service life of a welded piece product of the cable and the cable interface is prolonged.

Description

technical field [0001] The invention relates to the field of cable processing, in particular to a pre-installed fixture and its application, a welding piece and a welding method. Background technique [0002] In the prior art, the welding method of a cable with several pins and a cable interface includes the following steps: 1. Manually set a heat shrinkable tube on each core wire; 2. Put several cores in the cable Set the wires at the corresponding pins of the cable interface one by one; 3. Solder the joints of the core wire and the cable interface one by one; 4. Push the heat shrinkable tubes to the joints (welding parts) one by one, so that the joints Wrapped inside the heat-shrinkable tube, so as to realize the insulation isolation between the welding parts and avoid short circuit. The welding method in the prior art has the following defects: the operation steps are cumbersome and time-consuming. Contents of the invention [0003] The invention provides a pre-instal...
