Description

Technical Field

[0001] The utility model belongs to the field of electrical connectors, in particular to a waterproof connector. Background Art

[0002] Waterproof connectors are electrical connectors designed for use in wet or rainy environments. They are usually waterproof and sealed to prevent moisture, dust or other foreign matter from entering the connector, thus protecting the connector and its internal circuits from damage. These connectors are commonly found in outdoor equipment, automotive electronic systems, ships, and industrial equipment, and are usually designed with durability, corrosion resistance, and reliable electrical performance in mind.

[0003] The more common waterproof connectors include ring connectors, plug-in connectors, rectangular connectors and terminal connectors. The most commonly used connectors in factories are plug-in connectors, which have a simple structure and are easy to assemble and disassemble. They can provide basic waterproof protection under low pressure conditions and are suitable for scenarios such as factories where demand is low and a large number of installations are required.

[0004] The most common implementation methods of connectors in the industry are single waterproof and coordinated waterproof. The single waterproof solution mostly achieves waterproof function by injecting glue between the hardware guide and the insulating body. The waterproof performance is good, but it is difficult to disassemble and assemble during maintenance. The coordinated waterproof solution uses the elastic body set on the overall structure to fit with the insulating body to achieve waterproofing. However, due to the overall waterproof layout, the single wiring terminal is mostly fixed and cannot be disassembled for maintenance. When the wiring behind the port fails, the entire connector must be removed for maintenance, which also wastes a lot of time in maintenance work.

[0005] Therefore, a new design is needed that ensures waterproof effect but is more convenient for assembly and maintenance. Utility Model Content

[0025] The utility model is further described below in conjunction with specific embodiments.

[0026] like Figure 1 As shown, the utility model mainly includes a shell 1 and a protective cover 2, wherein the shell 1 is installed on the wall, the side facing the wall is the installation surface, and the side facing the outside is the wiring surface. The main function of the shell 1 is to pass through the wall to short-circuit the auxiliary wire.

[0027] A plurality of connectors 3 are provided in the housing 1. The specific structure of the connectors 3 is as follows: Figure 2 As shown, the specific structure of installing the connecting member 3 in the housing 1 is as follows Figure 3 shown.

[0028] The connector 3 is a structure with wire connectors at both ends connected by a guide member in the middle, wherein a fastening groove 4 is provided on the connector 3 at one end of the connector 3 facing the wiring surface, and the function of the fastening groove 4 is to fix the wire connected to the connector 3 on one side of the wiring surface of the housing 1. The fastening groove 4 used in this embodiment is a screw-type fastening groove 4, and the wire is inserted into the connector 3, and then the fastening screw is screwed into the fastening groove 4 with an internal thread opened on the side, and the wire is fastened to the connector 3 from the side. At the same time, in order to cooperate with the installation method of the fastening screw of the fastening groove 4, a through groove is opened at the position corresponding to the fastening groove 4 on the housing 1 in the drawings of the specification for fastening of the fastening screw, and in this embodiment, a plurality of connectors 3 are provided, and they are divided into upper and lower rows. In order not to affect the normal installation of each connector 3, the structure used in the drawings is to open the through groove above or below the connector 3 according to the actual position of the upper and lower rows of connectors 3.

[0029] The end of the connector 3 facing the mounting surface is not provided with an additional wire fixing groove 5 of the fastening structure, but the shell of the wire fixing groove 5 is thinner than the shell of the fastening groove 4 of the connector. The wires on the wiring surface need to be replaced and connected according to the electrical equipment, while the wires connected to the mounting surface do not need to be replaced and connected a second time. Therefore, the wires connected to the wire fixing groove 5 do not need the auxiliary wire connection of the fastening groove 4 that can be quickly disassembled and assembled. Therefore, in this embodiment, the wire connection in the wire fixing groove 5 can be connected by crimping or welding, and the connection is more stable and not easy to loosen.

[0030] A sealing ring 6 is arranged on the periphery of the guide part in the middle of the connector 3, and the sealing ring 6 makes each connector 3 installed on the housing 1 have a waterproof function in its installation slot, that is, to achieve waterproofness of a single connector 3.

[0031] The portion of the shell 1 on the wiring surface side where the connector 3 is installed is provided with an elastic hook protruding outward, and the protective cover 2 arranged on the wiring surface side of the shell 1 is provided with a tenon corresponding to the elastic hook of the shell 1. Through the connection of the buckle, the protective cover 2 and the shell 1 can be quickly disassembled and assembled.

[0032] like Figure 4 As shown, a circle of sealing gasket 7 is also provided on the portion of the housing 1 where the protective cover 2 is installed. The portion where the protective cover 2 contacts the housing 1 wraps the entire housing 1. The sealing gasket 7 is arranged around the housing 1 to achieve waterproofing between the protective cover 2 and the housing 1. The overall structure of the protective cover 2 is a downwardly inclined cover structure. When the connector is working in an outdoor environment, rainwater will slide down along the inclined direction of the protective cover 2, and will not form water accumulation above the protective cover 2. At the same time, due to the effect of the sealing gasket 7, rainwater will not flow along the gap between the protective cover 2 and the housing 1 into the area where the wire is connected to the connector 3.

[0033] In order to prevent liquid from flowing into the installation surface of the housing 1 from the gap between the housing 1 and the wall, a sealing pad 8 is provided on the flange surface of the housing 1 installed toward the wall, and then fixed to the wall by bolts to achieve waterproofing of the installation surface.

[0034] During actual installation, first connect the wires on the installation surface to one end of the connector 3 by crimping or welding, then install the outer flange of the housing 1 on the wall by bolts, and then connect the wires through the center of the protective cover 2 to one end of the wiring surface of the connector 3 according to the actual wiring requirements, and fasten the wires through the fastening groove 4 of the connector 3. After the wires on all wiring surfaces are connected, finally install the protective cover 2 along the wires to one side of the wiring surface of the housing 1, and fasten it with the snap-on structure to complete the installation and wiring of the connector.

[0035] The housing 1 of this solution is designed with a mounting groove for the connector 3 according to customer needs, and a wiring harness matching the number of connectors 3 is prefabricated. A triple all-round waterproof function is achieved through a sealing ring 6, a sealing gasket 7, and a sealing pad 8. The overall structure is simple and easy to install. The protective cover 2 is quick and easy to disassemble during maintenance, and each individual connector 3 can be taken out separately for maintenance. It can be widely used in on-site wiring and outdoor scenes with waterproofing requirements.
