Description

Technical Field

[0001] This utility model relates to a four-terminal distributor, and more specifically, to a four-terminal distributor with a manual vent valve. Background Technology

[0002] A distributor is a device used for current or signal distribution. It can split a single current or signal into multiple paths. Therefore, a distributor will have multiple connection ports, one of which is used as a current or signal connection port, and the others are used as current or signal output ports to deliver current or signals to other devices or other distributors.

[0003] Most existing four-terminal distributors are exposed to the external environment for extended periods. If the external environment is humid, moisture entering the distributor and not being expelled in time can easily lead to oxidation of internal components, affecting the overall product's usability. Therefore, it is necessary to add a breathable function. Existing waterproof breathable valves, when assembled onto four-terminal distributors, mostly achieve the effect of preventing dust and water from entering while allowing air to pass through through an internal waterproof breathable membrane. However, if placed in a dusty environment, dust will accumulate on the breathable membrane through the vents, causing it to malfunction.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a four-end distributor with a manual vent valve.

[0006] The technical solution of this utility model is:

[0007] A four-end distributor with a manual vent valve includes a detachably connected upper cover and a lower cover. The lower cover is provided with a valve body for moisture to pass through. The valve body has a vent channel communicating with the interior of the lower cover. The outer peripheral wall of the valve body has an external thread and is threadedly connected to the lower cover. The vent of the vent channel is located on the outer peripheral wall of the valve body and is located at the thread.

[0008] The present invention is further configured such that a recessed hole is formed on the surface of the lower cover, an internal thread that mates with the valve body is formed on the inner peripheral wall of the recessed hole, and a vent hole that communicates with the lower cover body is formed on the inner bottom wall of the recessed hole, and the vent hole communicates with the venting channel.

[0009] The present invention is further provided that a breathable membrane is provided on the bottom wall of the concave hole.

[0010] The present invention is further configured such that the valve body includes a covering part that fits against the surface of the top cover and a mounting part that mates with the recessed hole, the external thread is formed on the outer peripheral wall of the mounting part, the diameter of the covering part is larger than the diameter of the recessed hole, the mounting part is hollow and communicates with the vent hole, and the vent of the vent channel is formed on the outer peripheral wall of the mounting part.

[0011] The present invention is further configured such that the distance from the vent to the cover is less than the distance from the internal thread to the opening of the concave hole.

[0012] The present invention is further provided that a sealing ring is fitted on the outer peripheral wall of the mounting part, and the sealing ring is located between the vent and the cover part.

[0013] The present invention is further provided that a tool slot is provided on the top of the cover portion.

[0014] The beneficial technical effects of this utility model are:

[0015] The valve body is threaded into the recessed hole so that the cover fits against the surface of the lower cover, completely sealing the recessed hole and preventing the breathable membrane from being completely exposed to the air. This prevents the four-end distributor from being in a dusty environment, where dust will cover the breathable membrane and affect its normal use.

[0016] When the valve body is loosened, the vent hole is unscrewed, allowing the ventilation channel to connect with the outside, thereby achieving the ventilation effect. This allows the moisture inside the entire distributor to be discharged, preventing moisture accumulation inside the distributor and avoiding oxidation of the PCB board and components inside the distributor. It also achieves the effect of balancing the exhaust pressure difference, ensuring the service life of the entire four-terminal distributor and the service life of the components inside the four-terminal distributor.

[0023] In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] A four-terminal distributor with a manual vent valve, such as Figures 1-5 As shown, it includes a detachably connected upper cover 1 and a lower cover 2. The lower cover 2 is provided with a valve body 3 for moisture to pass through. The valve body 3 has a venting channel that communicates with the interior of the lower cover 2. The outer peripheral wall of the valve body 3 has an external thread that is threaded to the lower cover 2. The vent 321 of the venting channel is located on the outer peripheral wall of the valve body 3.

[0025] The lower cover 2 has a recessed hole 4 on its surface. The inner circumferential wall of the recessed hole 4 has an internal thread that mates with the valve body 3. The inner bottom wall of the recessed hole 4 has a vent hole 41 that communicates with the interior of the lower cover 2 and is connected to a venting channel. A venting membrane 6 is provided on the inner bottom wall of the recessed hole 4. The valve body 3 includes a covering part 31 that fits against the surface of the lower cover 2 at the top and a mounting part 32 that mates with the recessed hole 4. An external thread is formed on the outer circumferential wall of the mounting part 32. By mates the internal thread with the external thread of the mounting part 32, the valve body 3 can be threadedly connected to the recessed hole 4. The threaded connection provides a good sealing effect and also has a high degree of... Good fixing effect; the diameter of the cover part 31 is larger than the diameter of the concave hole 4, which can completely cover the concave hole 4, thus ensuring the sealing effect. The mounting part 32 is hollow and communicates with the vent hole 41. The vent 321 of the vent channel is opened on the outer peripheral wall of the mounting part 32. The valve body 3 is made of plastic material. The side of the cover part 31 facing the mounting part 32 is set in an arc shape, which has a good guiding effect. Since it is made of plastic material, it has a certain elasticity. When the valve body 3 is tightened, the bottom side of the cover part 31 will be squeezed and can be embedded into the concave hole 4, thereby further ensuring the sealing effect of the valve body 3.

[0026] A vent 321 is located at the end of the external thread near the cover 31. The distance from the vent 321 to the cover 31 is less than the distance from the internal thread to the opening of the recess 4, so that the valve body 3 can be completely retracted into the recess 4 when tightened, thus ensuring a sealing effect. Since the vent 321 is located at the end of the external thread near the cover 31, when the valve body 3 is loosened, the vent 321 unscrews out of the recess 4, allowing the venting channel to connect with the outside, thus achieving a ventilation effect. This allows moisture inside the distributor to escape, preventing moisture accumulation and damage to internal components. A sealing ring 5 is fitted on the outer peripheral wall of the mounting part 32, located between the air inlet and the cover 31. The sealing ring 5 further ensures the sealing effect between the valve body 3 and the recess 4. A tool groove 311 is provided on the top of the cover 31, which can be a slotted or Phillips head, allowing the valve body 3 to be rotated using a screwdriver, making rotation of the valve body 3 more convenient.

[0027] Working principle: After the entire four-terminal distributor is installed, the valve body 3 is threaded into the recess 4 so that the cover 31 fits against the surface of the lower cover 2, completely sealing the recess 4, preventing the breathable membrane 6 from being completely exposed to the air, and preventing the four-terminal distributor from being in a dusty environment, where dust will cover the breathable membrane 6 and affect its normal use.

[0028] When ventilation is required, the operator only needs to use a screwdriver to loosen the valve body 3, and the vent 321 will unscrew the concave hole 4, so that the ventilation channel is connected to the outside, thereby achieving the ventilation effect. This allows the moisture inside the entire distributor to be discharged, preventing moisture accumulation inside the distributor, avoiding oxidation of the PCB board and components inside the distributor, and also achieving the effect of balancing the exhaust pressure difference, ensuring the service life of the entire four-terminal distributor and the service life of the components inside the four-terminal distributor.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
