AI Technical Summary
When connecting the multi-core wire, traditional terminal connectors are prone to core bias, terminal inadequate and pin breakage, resulting in unstable plug-in and damage to the equipment.
A welded terminal connector is designed. By setting up a mounting cavity and baffle on the back of the connector body, the anti-stupid mechanism and the rear cover are used to ensure horizontal insertion and welding of the upper and lower terminals, preventing misoperation, and passing through arc shape. The through holes and C-type inverted groove limits ensure the correct installation direction.
The stability and safety of terminal connection are achieved, the core bias and pin removal are avoided, the processing efficiency and product reliability are improved, and the outflow rate and production costs of defective products are reduced.

Technical Field
[0001] The invention relates to a connector, in particular to a welding terminal connector and an installation method. Background Art
[0002] Terminal connectors are electronic components used to make connections between circuits. They are usually used for electrical connections between wires, between wires and boards, or between circuit boards. Terminal connectors can be simple single connection points or complex assemblies with multiple connection points to suit different technologies and application requirements.
[0003] Terminal connectors are designed to ensure stable and safe transmission of current or signals, and can be easily connected and disconnected as needed. They play a vital role in a variety of fields such as electronic products, industrial equipment, automobiles, communication equipment, and home appliances.
[0004] In traditional terminal connectors, there are the following hidden dangers: 1. Core deviation: When the multi-core wire passes through the connector body, the core wire will be pulled, causing the terminal to deviate from the center when passing through the shell. (When the finished product is used, there will be a phenomenon that it cannot be plugged in or the terminal is damaged) 2. The terminal is not in place: When the core wire is pulled, the processing personnel will interfere with the wires and may not be put in place.
[0005] 3. Pin removal: Since the terminal is not fully inserted, there is a possibility of pin rejection (although the reverse pull process guidance has "prevention", it has not been effectively implemented in the industry). Summary of the invention
[0006] The technical problem to be solved by the present invention is to provide a welding terminal connector to solve the problems of core deviation, terminal failure and pin stripping in the background technology.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0019] like Figure 1-Figure 3 As shown, a welding terminal connector of the present invention comprises: A connector body 1, wherein a mounting cavity 4 is provided at the back of the connector body 1; The baffle 2 is provided with an upper terminal 5 and a lower terminal 6 above and below the baffle 2, so that the upper terminal 5 and the lower terminal 6 are arranged horizontally; the welding ends of the upper terminal 5 and the lower terminal 6 are welded with core wires; the baffle 2 is arranged in the installation cavity 4 through an anti-fool mechanism to prevent misoperation and ensure the safe use of the equipment; the connection ends of the upper terminal 5 and the lower terminal 6 are horizontally inserted into the plug-in end of the connector body 1; The rear cover 3 is buckled and arranged on the back side of the connector body 1 and contacts the baffle 2 .
[0020] The connector body 1 is provided with an upper port 7 and a lower port 8 , and the upper terminal 5 and the lower terminal 6 above and below the baffle 2 are inserted into the upper port 7 and the lower port 8 respectively.
[0021] In addition, the welding ends of the upper terminal 5 and the lower terminal 6 are arranged in an arc shape, and an arc-shaped through hole 9 corresponding to the upper terminal 5 and the lower terminal 6 is arranged on the baffle 2, and the welding ends of the upper terminal 5 and the lower terminal 6 pass through the arc-shaped through hole 9 and are placed on the supporting end 10 of the baffle 2.
[0022] Among them, the anti-mistake mechanism includes a C-shaped groove 11 arranged on the installation cavity 4 and a C-shaped chamfer 12 arranged on the baffle 2; the limiting function of the C-shaped groove and the C-shaped chamfer 12 can prevent the baffle 2 from having the wrong direction during the installation process, ensuring the accuracy of the installation.
[0023] Wherein, spacer bars 13 are provided above and below the supporting end 10 of the baffle plate 2 for spacing.
[0024] A method for installing a welding terminal connector of the present invention specifically comprises the following steps: S1. After fixing the upper terminal and the lower terminal on the baffle, weld the core wire; S2. Place the baffle plate in the mounting cavity on the back of the connector body, and squeeze the rear cover onto the baffle plate; S3, the core wire is passed through the rear cover, and the connecting ends of the upper terminal and the lower terminal are pushed through the rear cover to be horizontally inserted into the plug-in end of the connector body; S4, the back cover is buckled with the back of the connector body; S5. In summary, the assembly of the welding terminal connector is completed.
[0025] like Figure 4 As shown: The process is as follows: First peel off the outer rubber, then peel off the core wire rubber; place it on the wire rack (and baffle); then weld the core wire to the terminal; after welding, check each core wire terminal, and finally install the back cover to form the outer mold.
[0026] A. Successfully reduce processing time and cost in the processing process With the recent increase in raw material and labor costs, customers are unable to absorb all the rising costs. This optimization action can alleviate the cost pressure on customers and give them some buffer space.
[0027] B. Make large improvements in the reliability of new designs: B1: After inserting into the shell: The terminal is tilted + not inserted into place: Due to the multi-core wires, there may be many reasons during assembly, causing the (terminal) to tilt at a certain place when inserting into the connector body; causing resistance to the overall insertion / extraction; in severe cases, the terminal may break when used for insertion.
[0028] After the improvement: Because the terminals are first placed on the terminal baffle and then driven into the connector body as a whole with a jig, the problems of individual terminals tilting, terminals not being properly installed, and taking more time for inspection can be completely avoided, which greatly reduces the defective product outflow rate; B2: In the traditional method, it takes a long time to drill the port and pierce the shell, and the equipment is occupied, resulting in low processing benefits and efficiency; The existing solution to improve it is to use motion calculation. The existing operation is through: core wire termination + terminal shell penetration + machine / inspection means (which still has risks); The invention provides a core wire baffle, welding + direct external mold forming, no other steps are required, and the efficiency is higher.
[0029] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
