The invention provides a connecting process of a cable and a terminal, which is used for connecting a cable 2 and the terminal 1.
Referring to fig. 1 to 4, in an embodiment of the present invention, a connection process of the cable and the terminal includes the following steps:
s1: peeling the cable 2 so that the conductor 21 of the cable 2 is exposed;
s2: inserting the conductor 21 into the connection hole 111 of the connection part 11;
s3: performing a crimping process on the conductor 21 and the connection part 11;
s4: winding the tin wire at a position where the conductor 21 is adjacent to the free end of the connecting part 11;
s5: and carrying out welding treatment on the tin wire.
In this embodiment, the material of the terminal 1 is the conductor 21, and generally, a metal material with good conductivity such as copper and aluminum is selected, and the terminal is cheap and easy to process. One end of the terminal 1 is provided with a connecting part 11, and the connecting part 11 is provided with a connecting hole 111 for conveniently inserting the conductor 21 of the cable 2 therein for connection; the other end of the terminal 1 may be soldered or screwed with other conductive members to achieve electrical connection. Specifically, the terminal 1 is provided with a threaded hole at one end away from the connecting portion 11, and is connected with the conductive component by threads, so that stable connection can be realized, and the situation that the terminal is accidentally torn apart is not easy to happen, thereby ensuring the stability of connection of the cable 2. Of course, the terminal 1 may have a flat end facing away from the connecting portion 11, and a connecting hole 111 is formed therein, and the terminal is connected to another conductive member by inserting a fixing member into the connecting hole 111.
The cable 2 to be connected is generally composed of a conductor 21, a main insulating layer, a shielding layer and a sheath, and when the cable 2 is installed and connected, the sheath of the cable 2 is peeled off for a certain length, then a section of the shielding layer is peeled off, and then a part of the main insulating layer is peeled off, so that the conductor 21 is exposed to be connected with the terminal 1. The cable 2 is in a stepped shaft shape after being processed, and the conductor 21 is matched with the diameter of the connection hole 111 of the connection part 11 to realize reliable connection. The conductor 21 is mainly a copper wire, has good conductivity, and can be cleaned of foreign matters or oxides before connection, so as to realize better electrical connection.
Specifically, the diameter of the tin wire wound on the conductor 21 of a conventional size is in the range of 0.6-1.0 mm, and the number of turns of the tin wire wound is in the range of 6-10, so that the soldered tin liquid can effectively fill the gap between the conductor 21 and the end of the connection part 11. Of course, when the diameter of the cable 2 is increased, the diameter and the number of windings of the corresponding tin wire should be increased accordingly, so as to ensure good contact performance between the conductor 21 and the terminal 1.
The tin wire is preferably made of silver-containing tin wire, has good adhesion performance, can be quickly filled on the outer surface and the inner part of the conductor 21, and improves the processing efficiency; and the silver-tin-containing wire has good conductivity, so that the contact performance between the conductor 21 and the terminal 1 can be further improved, the contact resistance is reduced, and the heating temperature of the conductor 21 can be effectively reduced when large current passes through the conductor, so that the aging of the cable is delayed.
According to the connecting process of the cable and the terminal, the tin wire is wound at the position, close to the free end part of the connecting part 11, of the conductor 21, and then welding treatment is carried out on the position, so that the tin wire can fill the gap between the end part of the connecting part 11 and the conductor 21 after being melted, external air is prevented from entering, the copper conductor 21 can be prevented from being oxidized by oxygen because tin has higher oxidation resistance than copper, the copper conductor 21 can also keep good electrical performance and conductivity after being used for a period of time, the service life of the cable is prolonged, and the connecting performance of the connector is improved.
Further, at "step S2: inserting the conductor 21 into the connection hole 111 of the connection part 11 "includes:
s21: winding the tin wire into a disc shape and placing the tin wire into the connecting hole 111 of the connecting part 11;
s22: inserting a conductor 21 into the connection hole 111 and abutting the tin wire;
s23: the connection portion 11 is subjected to a soldering process corresponding to a free end position of the conductor 21.
In this embodiment, the tin wire is wound into a disk shape, which may be a disk shape or a square shape, or the tin wire may be cut into a powder shape and placed in the connection hole 111. The tin silk here can be the same with the tin silk of conductor 21 free end, and twine into the preferred 2 ~ 3mm of disc tin silk thickness, can satisfy the clearance of conductor 21 tip and fill, realizes effective connection, and can not pass through extravagantly.
Before crimping, winding a tin wire at the free end of the conductor 21, and firstly performing welding treatment on the conductor 21 in the connecting hole 111 to melt the tin wire at the free end of the conductor 21 and fill a gap between the end of the conductor 21 and the connecting hole 111, so that the operation is simple, the contact area between the conductor 21 and the terminal 1 is increased, the contact performance is improved, and meanwhile, when current passes through the conductor 21 and the terminal 1, the current can directly flow from the conductor 21 to one end of the terminal 1, which is far away from the connecting part 11, so that the electrical connection efficiency is effectively improved, and the requirement on the thickness of the connecting part 11 of the terminal 1 can be reduced; and then, the crimping treatment is carried out, so that the tin liquid can be filled in the conductor 21, the cross section area of the conductor 21 is increased, the contact resistance is further reduced, and the problem of heating can be effectively relieved when a large-current circuit is communicated. In addition, the process of winding the tin wire is simple and easy to operate, and the molten tin can automatically fill the gap, so that the processing efficiency can be effectively improved.
Of course, it is also possible to adjust the tin wire winding thickness at the free end of the conductor 21 so that the melted tin also fills the end of the connection 11.
Preferably, the welding process is non-contact high-frequency heating.
In the above steps, the device for welding the conductor 21 is a high-frequency heater, which is efficient and rapid, and can complete processing within several seconds, thereby effectively saving energy consumption; the processing mode is non-contact, so that scalding can be effectively prevented, and the operation safety is improved; the diameter of the inner induction coil may be slightly larger than the diameter of the terminal 1, and the applicability is strong regardless of the external shape of the conductor 21. When welding, the heating current of the high-frequency heater is 500-800A, the heating time is preferably 3-6 seconds, the connection performance and the electric contact performance of the cable 2 and the terminal 1 processed by the process are good, and the temperature rise when large current passes through can be effectively reduced.
Preferably, the crimping process is a regular hexagonal crimp.
The crimping treatment in the above steps selects regular hexagon crimping, and the crimping mode can apply uniform pressure to the conductor 21, so that the copper wire is uniformly stressed, the situation of local fracture cannot occur, and further the crimping resistance can be further reduced, and in the embodiment, the compression ratio of the copper wire is 75% -80%. The crimping process here can fill the gap between the conductor 21 and the hole wall of the connection hole 111 sufficiently with tin of the liquid, thereby completing effective electrical contact.
Further, at step S5: after the tin wire is subjected to the welding treatment, the method further comprises the following steps:
s6: a protective tube is sleeved between the end of the connecting part 11 and the outer skin of the cable 2.
In this embodiment, since the melting temperature of tin is higher than the temperature of the outer sheath of the conductor 21, in order to protect the outer sheath of the conductor 21 and prevent the conductor 21 from being oxidized, a protection tube, which is a heat shrinkable tube, is sleeved between the end of the connection portion 11 and the outer sheath of the cable 2, so that the cable 2 can be protected and the structural strength can be improved.
