Abstract
Description
Technical Field
[0001] This application relates to the field of electric actuator technology, and in particular to a water blocker. Background Technology
[0002] As we all know, more and more factories have adopted automated control, and manual operation has been replaced by mechanical or automated equipment. People require that the actuator can act as an interface between the control system and the mechanical movement of the valve, and further require that the actuator enhance its work safety and environmental protection performance. Therefore, electric actuators have been widely used.
[0003] Currently, wires are common components used to connect electrical appliances and power supplies. Ensuring the safe and stable operation of electric actuators is crucial. Improper wire connections can cause numerous problems. However, this applicant has discovered that after connecting wires to electric actuators, the outer sheath of the wires is prone to damage after prolonged use. To ensure normal operation, it is often necessary to break the wire at the damaged area, re-wrap it, and then wrap it with waterproof tape. However, this simple wrapping remedial measure can easily lead to electrical leakage. Furthermore, the wire connections are prone to loosening and detachment, and short circuits can easily occur when exposed to water, posing certain safety hazards. It may even directly cause the connected electric actuator to be scrapped, resulting in economic losses.
[0004] Therefore, in view of the above-mentioned technologies, we provide a water blocker that facilitates the protection of the wires connected to the electric actuator. Utility Model Content
[0005] The purpose of this invention is to provide a water blocker to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A water blocker, comprising:
[0008] The main body of the water blocker has an installation groove inside.
[0009] The PCB board body is disposed inside the water blocker body through a mounting groove;
[0010] Two sets of threaded layers are respectively disposed on the outer wall of the water blocker body;
[0011] Two lock nuts, both of which are threaded to the water blocker body via a threaded layer.
[0012] As a further improvement of this utility model: both ends of the water blocker body are provided with connecting grooves, and sealing rings are provided in the connecting grooves.
[0013] As a further improvement of this utility model, a waterproof coating is provided on the outer wall of the water blocker body.
[0014] As a further improvement of this utility model, a coating positioning block is provided at one end of the main body of the water blocker.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] In use, the wires at the damaged outer sheath are cut open, and then the two ends of the cut wires are soldered to the corresponding PCB motherboard. The PCB motherboard connects the separated wires together. Then, the PCB motherboard and wires are placed inside the water blocker body through the mounting groove. At the same time, one end of the lock nut is locked to the water blocker body through the threaded layer. Then, glue is poured in from the other end until full. The other end of the water blocker body is locked to the water blocker body through the interaction of the threaded layer and the lock nut. This achieves the purpose of sealing the PCB motherboard and connected wires inside the water blocker body. Its overall structure is relatively simple, making it easy to repair damaged wires and preventing the wires from loosening and falling off. In addition, it improves the waterproof performance of the wires, and its size is smaller than that of products on the market, saving space and facilitating its widespread use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] The present application will be further described in detail below with reference to the accompanying drawings.
[0024] Please see Figures 1-4 In this embodiment of the utility model, a water blocker is characterized by comprising:
[0025] The water blocker body 1 has an installation groove 2 inside it;
[0026] The PCB board body 3 is installed inside the water blocker body 1 through the mounting groove 2.
[0027] Two sets of threaded layers 4 are respectively set on the outer wall of the water blocker body 1;
[0028] Two lock nuts 5 are threadedly connected to the water blocker body 1 through the threaded layer 4.
[0029] In use, the wires at the damaged part of the outer sheath of this water blocker are cut open, and then the two ends of the cut wires are soldered to the corresponding parts of the PCB motherboard. The PCB motherboard connects the separated wires together. Then, the PCB motherboard body 3 with the soldered wires is placed inside the water blocker through the mounting groove 2 opened in the water blocker body 1. One end of the lock nut 5 is then locked to the water blocker body 1 through the thread layer 4. Then, glue is poured into the other end until it is full. Then, through the interaction between the thread layer 4 and the lock nut 5 on the other end of the water blocker body 1, the other lock nut 5 is locked to the water blocker body 1. This seals the PCB motherboard and the connected wires inside the water blocker body 1, improving the waterproof performance of the wires soldered on the PCB motherboard.
[0030] exist Figure 1-4 In the middle: both ends of the water blocker body 1 are provided with connecting grooves, and the connecting grooves are provided with sealing rings 6 to improve the waterproof performance of the lock nut 5 to the water blocker body 1. The outer wall of the water blocker body 1 is provided with a waterproof coating 7, and one end of the water blocker body 1 is provided with a coating positioning block 8. The waterproof coating 7 and the coating positioning block 8 can prevent the water blocker body 1 from being corroded by water and improve its service life.
[0031] The implementation principle of a water blocker according to an embodiment of this application is as follows: First, the wire at the damaged part of the outer sheath can be cut open, and then the two ends of the cut wire are respectively soldered to the PCB motherboard. Then, the wires required for the PCB board body 3 are correspondingly soldered to the PCB motherboard. The PCB motherboard serves to connect the separated wires together. Then, through the mounting groove 2 opened in the water blocker body 1, the PCB board body 3 with the soldered wires is placed in the water blocker. Then, one end of the lock nut 5 is locked to the water blocker body 1 through the thread layer 4. Then, glue is poured into the other end until it is full. Then, through the mutual cooperation between the thread layer 4 and the lock nut 5 at the other end of the water blocker body 1, the other lock nut 5 is locked to the water blocker body 1, thereby sealing the wires soldered to the PCB motherboard inside the water blocker body 1.
