Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a waterproof connector that is easy to plug and unplug. Background Technology

[0002] Connectors generally refer to electrical connectors, which are devices that connect two active devices to transmit current or signals. They bridge gaps in circuits or between isolated circuits, thus enabling circuit continuity. Connectors are indispensable components in electrical systems. Existing connectors typically involve inserting the male and female heads together and then tightening them with a threaded sleeve. While the threaded sleeve provides waterproofing, some water or moisture can still seep into the connector's connection points, causing short circuits. The waterproofing effect is poor. Furthermore, after connecting with the threaded sleeve, when the connector needs to be removed, the operator must first loosen the threaded sleeve and then pull the male and female heads apart, making insertion and removal inconvenient. Therefore, we propose a waterproof connector that facilitates easy insertion and removal. Utility Model Content

[0003] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by providing a waterproof connector that is easy to plug and unplug.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof connector that is easy to plug and unplug is designed, including a male head and a female head. One end of the male head is connected to a terminal, and one side of the terminal is connected to several plugs. A receiving groove is provided at the end of the female head near the male head. Several slots are provided inside the receiving groove, and one end of each plug extends into the corresponding slot.

[0005] A sealing sleeve is installed on one edge of the female head. When the male head abuts against the end of the female head, the sealing sleeve is fitted onto the outer surface of the male head.

[0006] Several elastic metal pieces are installed at the end of the female head near the sealing sleeve. One end of each elastic metal piece is fixed to the corresponding side of the sealing sleeve, and the end of each elastic metal piece near the sealing sleeve is bent outward.

[0007] The female head has a sliding sleeve with a limiting sleeve on one side. When the sealing sleeve is on the outer surface of the male head, the limiting sleeve slides on the side of the male head, and the sealing sleeve is located between the male head and the limiting sleeve.

[0008] The inner surface of the sealing sleeve is equipped with at least one sealing ring, and the outer surface of the male head is provided with at least one sealing groove. When the limiting sleeve is fitted onto the outer surface of the male head, the inner rings of the sealing rings all extend into the corresponding sealing grooves.

[0009] Preferably, when the plug is inserted into the corresponding slot, one end of the tip moves into the receiving groove, and the outer surface of the tip is sealed to the inner sidewall of the receiving groove.

[0010] Preferably, the sealing sleeve is made of elastic rubber material.

[0011] Preferably, the sealing sleeve is flared when the limiting sleeve detaches from the outer surface of the sealing sleeve.

[0012] Preferably, a connecting ring is installed on the side of the male head, and a groove is opened on one side of the connecting ring, with one end of the limiting sleeve extending into the groove;

[0013] Several magnetic blocks are installed on the inner end face of the groove, and the sides of the magnetic blocks are attracted and fixed to the end of the limiting sleeve.

[0014] Preferably, when one end of the limiting sleeve is located in the groove, the outer side of the limiting sleeve is sealed to the inner wall of the groove.

[0015] Preferably, a sealing gasket is installed at the end of the receiving slot, and when the plug is inserted into the slot, the end of the plug abuts against the side of the sealing gasket.

[0016] The design scheme proposed in this utility model has the following beneficial effects in application:

[0017] 1. The sealing sleeve can cover the connection between the male and female connectors. With the cooperation of the sealing ring and sealing groove, multiple seals can be formed at the connection between the male and female connectors to prevent external rainwater or moisture from seeping into the connection between the male and female connectors, thus improving the waterproof effect.

[0018] 2. The elasticity of the elastic metal sheet allows the sealing sleeve to open, and then the limiting sleeve tightly fits the sealing sleeve onto the male head. In this way, when inserting or removing, you only need to remove the limiting sleeve from the sealing sleeve, and the sealing sleeve can be separated from the outer surface of the male head. This will not hinder the insertion or removal of the male and female heads, making insertion and removal convenient. Attached Figure Description

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-3 A waterproof connector for easy insertion and removal includes a male connector 1 and a female connector 6. One end of the male connector 1 is connected to a terminal 14, and a plurality of plugs 10 are connected to one side of the terminal 14. A receiving groove 9 is provided at the end of the female connector 6 near the male connector 1. A plurality of slots 8 are provided inside the receiving groove 9. One end of each plug 10 extends into the corresponding slot 8. Wires are connected to the ends of the male connector 1 and the female connector 6 that are far apart from each other. In actual use, the male connector 1 and the female connector 6 can be connected together by inserting the plug 10 into a unique slot 8, thereby connecting the two wires.

[0024] like Figure 1 and Figure 3 As shown, a sealing sleeve 4 is installed on one end edge of the female connector 6. When the male connector 1 and the end of the female connector 6 abut together, the sealing sleeve 4 is placed on the outer surface of the male connector 1. The sealing sleeve 4 can seal the connection between the female connector 6 and the male connector 1, thereby preventing rainwater or other liquids from seeping into the connection between the male connector 1 and the female connector 6. In this way, the connection between the male connector 1 and the female connector 6 will not short-circuit due to moisture.

[0025] like Figure 1 and Figure 2 As shown, several elastic metal pieces 5 are installed on one end of the female head 6 near the sealing sleeve 4. One end of each elastic metal piece 5 is fixed on the corresponding side of the sealing sleeve 4, and the end of each elastic metal piece 5 near the sealing sleeve 4 is bent outward. When the male head 1 and the female head 6 are not connected, the elasticity of the elastic metal piece 5 will open the opening of the sealing sleeve 4, so that the sealing sleeve 4 will not cause any obstruction during installation and disassembly.

[0026] like Figure 1 As shown, when the limiting sleeve 7 is removed from the outer surface of the sealing sleeve 4, the sealing sleeve 4 is set in a trumpet shape. In actual use, when the limiting sleeve 7 is removed from the sealing sleeve 4, the elastic metal sheet 5 will open the sealing sleeve 4, so that the inner surface of the sealing sleeve 4 will be separated from the outer surface of the male head 1. In this way, the sealing sleeve 4 will not hinder the separation of the male head 1 and the female head 6, and it is convenient to insert and remove.

[0027] It should be noted that the sealing sleeve 4 is made of elastic rubber material, or other elastic sealing materials are also acceptable. Under the elastic force of the elastic metal sheet 5, the sealing sleeve 4 will extend. When the limiting sleeve 7 moves to the end of the sealing sleeve 4 and squeezes the sealing sleeve 4, the sealing sleeve 4 will retract to its original state, so there will be no gap between the sealing sleeve 4 and the male head 1.

[0028] like Figure 2 and Figure 3 As shown, the female head 6 has a sliding sleeve with a limiting sleeve 7 on one side. When the sealing sleeve 4 is fitted on the outer surface of the male head 1, the limiting sleeve 7 slides on the side of the male head 1, and the sealing sleeve 4 is located between the male head 1 and the limiting sleeve 7. In actual use, when the limiting sleeve 7 slides along the sealing sleeve 4, the limiting sleeve 7 will squeeze the sealing sleeve 4, causing the sealing sleeve 4 to shrink and tightly adhere to the surface of the male head 1, thus sealing the connection between the male head 1 and the female head 6.

[0029] like Figure 2 and Figure 3 As shown, a connecting ring 2 is installed on the side of the male head 1. A groove 11 is provided on one side of the connecting ring 2. One end of the limiting sleeve 7 extends into the groove 11. The limiting sleeve 7 can be positioned through the groove 11. In this way, when the operator moves the limiting sleeve 7, the limiting sleeve 7 will not come off from the end of the sealing sleeve 4 near the male head 1.

[0030] like Figure 3 As shown, several magnetic blocks 13 are installed on the inner end face of the groove 11. The side of the magnetic block 13 is attracted and fixed to the end of the limiting sleeve 7. The limiting sleeve 7 can be attracted and fixed by the magnetic block 13, thus completing the fixation. The fixation is convenient.

[0031] like Figure 1 and Figure 2 As shown, at least one sealing ring 3 is installed on the inner surface of the sealing sleeve 4, and at least one sealing groove 12 is opened on the outer surface of the male head 1. When the limiting sleeve 7 is fitted on the outer surface of the male head 1, the inner rings of the sealing rings 3 all extend into the corresponding sealing grooves 12. In actual use, under the compression of the limiting sleeve 7, the sealing rings 3 inside the sealing sleeve 4 will move into the corresponding sealing grooves 12, further improving the sealing effect of the connection between the male head 1 and the female head 6.

[0032] Specifically, in use, the operator inserts the plug 10 on the male connector 1 into the slot 8 on the female connector 6, and simultaneously inserts the end 14 on the male connector 1 into the receiving groove 9 on the female connector 6. At the same time, the sealing sleeve 4 is placed on one end of the male connector 1. Then, the operator moves the limiting sleeve 7 towards the sealing sleeve 4. When the limiting sleeve 7 moves to the other end of the sealing sleeve 4 and one end of the limiting sleeve 7 is inserted into the groove 11 and attracted and fixed by the magnetic block 13, the sealing sleeve 4 is tightly adhered to the surface of the male connector 1 under the pressure of the limiting sleeve 7, thus sealing the surface. The sealing ring 3 installed on the inner surface of sleeve 4 moves into the corresponding sealing groove 12 to seal the connection between male head 1 and female head 6. This prevents the connection between female head 6 and male head 1 from getting damp and short-circuiting during use. When disassembly is required, the operator moves the limiting sleeve 7 towards female head 6, causing the limiting sleeve 7 to disengage from the sealing sleeve 4. Under the elastic force of the elastic metal sheet 5, the sealing sleeve 4 will open, separating the inner surface of the sealing sleeve 4 from the outer surface of male head 1. Thus, the operator only needs to gently pull male head 1 and female head 6 to remove the plug 10 from the slot 8 and complete the separation.

[0033] Furthermore, such as Figure 3 As shown, when the plug 10 is inserted into the corresponding slot 8, one end of the end 14 moves into the receiving groove 9, and the outer surface of the end 14 is sealed to the inner side wall of the receiving groove 9. This can further seal the connection between the male plug 1 and the female plug 6 and improve the sealing effect.

[0034] Furthermore, such as Figure 1 As shown, when one end of the limiting sleeve 7 is located in the groove 11, the outer side of the limiting sleeve 7 is sealed to the inner wall of the groove 11, which can seal the gap between the limiting sleeve 7 and the connecting ring 2, thereby further improving the sealing performance of the connection between the male head 1 and the female head 6.

[0035] Furthermore, such as Figure 3 As shown, a sealing gasket 15 is installed at the end of the receiving groove 9. When the plug 10 is inserted into the slot 8, the end of the tip 14 abuts against the side of the sealing gasket 15. During the connection process, the tip 14 will tightly abut against the sealing gasket 15, sealing the gap between the tip 14 and the receiving groove 9, thus improving the sealing effect. The above description is only a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model.
