Description

Technical Field

[0001] This utility model relates to the field of power supply and signal wiring technology, and in particular to a waterproof and sealed connector. Background Technology

[0002] During the wiring process, signal and power cables are introduced from the outside into the equipment. An inlet hole is made in the equipment, and then the cable is connected to the wiring terminal inside the equipment via a connector, forming a wiring channel. However, it is difficult to achieve good sealing at the inlet hole and connector locations. In harsh outdoor conditions, wind and rain can easily enter the equipment through the connector, affecting its normal operation.

[0003] The difficulty in achieving a seal lies in the fact that the connectors are threaded, creating gaps, and the cables are multi-stranded, making it impossible to form an effective seal between the multiple strands.

[0004] Therefore, the existing method is to fill the connection point with sealant or injection molding after the cable is wired. This method uses high temperature, which may damage the cable and adds process steps. During maintenance, the injected glue must be cut off, which is cumbersome and inefficient. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems and provide a waterproof and sealed connector. An effective seal is formed through the compression and deformation of the sealing block and the conical hole. Simultaneously, a seal is also formed between the cable and the wire hole, achieving a complete seal between the inlet and outlet ends.

[0006] The technical solution adopted by this utility model is:

[0007] A waterproof and sealed connector is characterized by comprising a connector base, wherein a cable channel is formed within the connector base, including an inlet end and an outlet end. The connector base at the outlet end is provided with mounting holes for mounting the connector base onto a device. The connector base at the inlet end is provided with a tapered hole, and a sealing block is provided within the tapered hole. The inlet end is locked onto the connector base by a threaded clamping structure, and the cable passes through the threaded clamping structure and the wire hole on the sealing block to connect to the outlet end.

[0008] Furthermore, the threaded clamping structure includes an internal thread provided at the front end of the tapered hole on the connector seat, and an external threaded sleeve. When the external threaded sleeve engages with the internal thread on the connector seat, it squeezes and seals the sealing block into the tapered hole.

[0009] Furthermore, a sealing ring is provided at the mating point between the external threaded sleeve and the connector seat.

[0010] Furthermore, a pressure plate is provided above the sealing block, and the pressure plate is provided with corresponding wire holes.

[0011] Furthermore, the dimensions of the wire holes on the sealing block and the pressure plate are such that the cable fits tightly with the wire holes on the sealing block and loosely with the wire holes on the pressure plate.

[0012] Furthermore, a vertical groove is provided on the inner side of the connector seat on one side of the inlet end, and a protrusion is provided on the side of the pressure plate. When the pressure plate is placed into the connector seat, the protrusion fits into the vertical groove, and the wire hole on the pressure plate is fixed to the position of the protrusion.

[0013] Furthermore, the connector seat at the outlet end is provided with a sealing groove for installing a sealing ring between it and the equipment.

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

[0015] (1) The sealing block achieves effective sealing by being squeezed through a conical hole;

[0016] (2) After the cable is inserted into the wire hole on the sealing block, it is squeezed to achieve effective sealing of multiple cables;

[0017] (3) Both the outgoing and incoming ends are sealed at the connection point by a sealing ring, forming a multi-seal effect with the sealing block. Attached Figure Description

[0032] The following detailed description of a waterproof sealing connector according to the present invention, with reference to the accompanying drawings, provides a specific embodiment of the present invention.

[0033] See appendix Figures 1 to 4 This patent's waterproof and sealed connector includes a connector base 1, within which a cable channel is formed. It includes an inlet end 2 and an outlet end 3. The connector base 1 at the outlet end 3 has mounting holes 4 for mounting the connector base 1 onto equipment. The connector base 1 at the outlet end 3 also has a sealing groove 5 for installing a sealing ring between it and the equipment. After installation, a seal can be achieved between the connector base 1 at the outlet end 3 and the equipment, and this seal can be relatively well achieved.

[0034] A tapered hole 6 is provided on the connector 1 of the inlet end 2. The tapered hole 6 is located inside the cable channel, with the tip of the tapered hole 6 pointing inward. A sealing block 7 is provided inside the tapered hole 6, and a wire hole 8 is opened on the sealing block 7. The size of the wire hole 8 is determined according to the number and thickness of the cables to be connected, so that there is a certain tension when the cable is inserted into the wire hole 8.

[0035] A threaded clamping structure 9 is fitted onto the cable. The inlet end 2 is locked onto the connector seat 1 through the threaded clamping structure 9. The cable passes through the threaded clamping structure 9 and the wire hole 8 on the sealing block 7 and connects to the outlet end 3.

[0036] See appendix Figure 5 The threaded clamping structure 9 includes an internal thread 10 located at the front end of the tapered hole 6 on the connector seat 1, and an external threaded sleeve 11. When the external threaded sleeve 11 engages with the internal thread 10 on the connector seat 1, it compresses and seals the sealing block 7 into the tapered hole 6. A sealing ring 12 is provided at the engagement point between the external threaded sleeve 11 and the connector seat 1.

[0037] See appendix Figure 6 A pressure plate 13 can be installed above the sealing block 7, with corresponding wire holes 8 on the pressure plate 13. The pressure plate 13 can evenly distribute the pressure transmitted by the external threaded sleeve 11 onto the sealing block 7. A protrusion 14 is provided on the side of the pressure plate 13, and a vertical groove (not shown in the figure) is provided on the inner side of the connector seat 1 on the side of the wire inlet 2. The protrusion 14 is used to cooperate with the vertical groove, so that the position of the wire hole 8 on the pressure plate 13 is basically fixed when the wire is threaded through. The wire hole 8 on the pressure plate 13 allows for easy insertion of the cable through the wire hole 8 with a loose fit. The sealing position is located at the sealing block 7, and the pressure plate 13 only serves as a support for pressure distribution.

[0038] When using the connector of this patent for cable connection, first thread the external threaded sleeve 11 of the threaded clamping structure 9 onto the cable. Then, thread the cable through the pressure plate 13 and the sealing block 7 in sequence. Push the sealing block 7 into the tapered hole 6 of the connector seat 1, and press the protrusion 14 of the pressure plate 13 into the vertical groove on the inner side of the connector seat 1. Then, press the external threaded sleeve 11 down onto the internal thread 10 of the connector seat 1 and tighten it. At this time, the pressure of the external threaded sleeve 11 on the pressure plate 13 causes the sealing block 7 to be squeezed and deformed, forming a seal between the cable and the wire hole 8, and also forming a seal between the sealing block 7 and the tapered hole 6. Finally, align the cable outlet 3 of the connector seat 1 with the mounting hole of the equipment.

[0039] Due to the effective sealing of the sealing ring between the equipment and the outlet terminal 3, the sealing ring 12 of the threaded clamping structure 9, and the sealing block 7, the connector meets the predetermined sealing requirements.

[0040] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
