Background technique

The current production capacity of domestic electrical appliance manufacturers urgently needs to be continuously improved. In order to reduce production costs, relying solely on expanding production sites and increasing the number of assembly lines not only increases costs, but also requires sufficient time to achieve. How to achieve the purpose of improving test efficiency and reducing labor intensity on the existing basis, so as to improve overall production efficiency and convenience of operation, is an urgent problem for manufacturers to solve. After the general assembly of household appliances is completed, when they are about to go off the production line, it is usually necessary to conduct a power-on test on their circuits. For example, for split-type household air conditioners, after the final assembly of the outdoor unit of the air conditioner, an online test machine is required, namely: Electrically connect the newly installed air conditioner outdoor unit in the production line with the inherent test indoor unit in the production line, and then conduct a trial run. In the prior art, the device for electrical connection between the outdoor unit of the air conditioner and the indoor unit for testing is usually: a wiring board is arranged on the electrical box of the outdoor unit of the air conditioner, and a screw hole and a wire joint composed of screws are arranged on the wiring board, and the lead-out of the testing indoor unit A wire is secured to the wire connector.

The power-on test of the outdoor unit of the air conditioner includes the following steps:

2) Use a screwdriver to fix each lead-out line of the indoor prototype used for testing on the wiring board of the outdoor unit;

3) Power on to test whether the outdoor unit of the air conditioner can operate normally and whether the test indicators are qualified;

4) Loosen the screws used to fix the lead wires of the indoor unit;

5) Unplug the lead wire of the indoor unit, and then tighten the screws;

6) The outdoor unit of the air conditioner leaves the station.

In the general assembly process of the outdoor unit of the air conditioner, this process alone takes about one minute before and after, and two special personnel must be equipped to handle the series of screwing-wiring-power-on-screw-unplugging actions. If the action is a little slow, it will be It will affect the speed of the entire production line. For a production line with a daily output of thousands of products, it will not only take a long time, but also increase labor intensity. At the same time, because workers disassemble and assemble the wires of thousands of products every day, once they cannot be reliably connected due to fatigue, or the connection and power-on procedures are reversed, there will be serious consequences that endanger personal safety. Based on the above reasons, it is very necessary to adopt new devices and technological processes, shorten the assembly time, and improve the efficiency and safety of the production line.

Disassembly process. Workers in the whole process only need to perform the three actions of plugging-powering-unplugging, and no longer need to set up a special person to be responsible for this process. Only workers in the previous or next process can take care of the test work. It only takes two seconds for the terminal board and the socket to start up and run, which is only one-thirtieth of the original time, which greatly improves the production efficiency and saves labor costs. At the same time, workers do not need to directly contact live parts (connecting wires, metal screws, etc.) during operation, the operation is simple, and the wiring and electrification procedures will not be reversed due to fatigue, eliminating potential safety hazards.

In addition to being used on split-type household air conditioners, the electrical appliance connection and wiring device of the present invention can also be used in other equipment that needs to be connected with wires. The specific implementation methods listed above are non-limiting. Therefore, various modifications and changes can be made without departing from the scope of the present invention. For example, the position and form of jacks and plugs, the implementation of grounding devices, the structure and connection relationship of various components, etc. In particular, the electrical connection forms of the multi-position wiring board components and the plug-and-socket components can be diversified, such as adopting a card slot mode similar to a telephone line, screw holes and stud connection methods, and the like.
