DETAILED DESCRIPTION

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1 to Figure 5 As shown, the present embodiment aims to provide a waterproof cable connector with good sealing performance and convenient construction. To this end, the waterproof cable connector provided by the present embodiment and convenient for construction includes a male connector 1 and a female connector 2. Since two sections of cables are connected, a male pin 4 is arranged on the male connector 1, and a female plug 5 matching the male pin 4 is arranged on the female connector 2. Both the male pin 4 and the female plug 5 are made of metal and are electrically connected to the cable. The main purpose of the male connector 1 and the female connector 2 is to fix the male pin 4 and the female plug 5 to the cable.

[0023] The above structure is a common existing structure, and therefore, it is not described in detail in this embodiment.

[0024] Taking into account that most cables are cylindrical structures, in this embodiment, the male connector 1 and the female connector 2 provided are both tubular in shape. Specifically, the male connector 1 and the female connector 2 both include a tube body 11 and a gripping claw 111 arranged at one end of the tube body 11. The gripping claw 111 is grooved at the end of the tube body 11 so that its end is divergently arranged. In this way, a locking nut 6 for locking the gripping claw 111 is also provided on the tube body 11. By twisting the locking nut 6, the gripping claw 111 can be squeezed to achieve fixation between the tube body 11 and the cable.

[0025] In order to achieve sealing, a first rubber sleeve 114 is provided in the tube body 11, and the cable passes through the rubber sleeve. Due to the elasticity of the rubber sleeve, the mouth of the rubber sleeve is slightly smaller than the diameter of the cable. In this way, the rubber sleeve can fit the surface of the cable to achieve the first level of sealing.

[0026] In order to achieve the connection between the cable and the male plug and the female plug 5, an electrical connection column 3 is also provided in the tube body 11, and the first rubber sleeve 114 is provided between the gripping claw 111 and the electrical connection column 3, so that the electrical connection column 3 is provided at the other end of the tube body 11. The end face of the electrical connection column 3 is provided flush with the end face of the tube body 11. In this embodiment, the electrical connection column 3 is provided in a columnar shape, and a wire entry blind hole 31 is provided at one end of the electrical connection column 3 close to the first rubber sleeve 114, and the wire entry blind hole 31 is used for the cable to pass through, and at the same time, a second rubber sleeve 37 is provided in the wire entry blind hole 31, and the second rubber sleeve 37 is provided in the same manner as the first rubber sleeve 114, and is provided in a manner that fits the cable, thereby achieving a second level of sealing. The male pin 4 and the female plug 5 are fixed to one end of the electrical connection column 3 away from the incoming blind hole 31. In order to realize the electrical connection between the cable and the male pin 4 and the female plug 5, a connection seat 35 is also provided in the incoming blind hole 31. A metal sheet and a nut are provided on the connection seat 35, wherein the metal sheet is electrically connected to the male pin 4 and the female plug 5. In this way, the conductor of the cable is fastened to the metal sheet by bolts, thereby realizing the electrical connection with the male pin 4 and the female plug 5.

[0027] In order to realize the connection and fixation between the male connector 1 and the female connector 2, a connection nut 7 is provided on the female connector 2, and the connection nut 7 can move at the end of the female connector 2. A limit plate is provided on the female connector 2 for realizing the limit, and an external thread matching with the connection nut 7 is provided on the pipe body 11 of the male connector 1. In this way, the connection between the male connector 1 and the female connector 2 is realized by using the connection nut 7.

[0028] Thus, through the above arrangement, two seals are effectively achieved by using the first rubber sleeve 114 and the second rubber sleeve 37, thereby preventing the possibility of the cable and the male connector 1 or the female connector 2 entering the connection. Thus, the purpose of waterproofing is achieved. At the same time, the structures provided in this embodiment are all threaded connections, which only need to be tightened, so the construction is convenient.

[0029] In order to further facilitate the construction, in this embodiment, the electrical connection column 3 can be inserted and fixed in the tube body 11. In this way, during the wiring process, the electrical connection column 3 can be not affected by the tube body 11, thereby achieving connection.

[0030] In order to facilitate the fixation between the electrical connecting column 3 and the tube body 11, in the present embodiment, a locking bead 34 is provided on the side wall of the electrical connecting column 3. Specifically, a hole is provided on the side wall of the electrical connecting column 3, the locking bead 34 is provided in the hole and a locking spring is provided between the locking bead 34 and the electrical connecting column 3, so that the locking column can be telescopically provided in the hole. At the same time, an annular groove 112 matching the locking bead 34 is provided on the side wall of the tube body 11.

[0031] In order to prevent water from entering through the gap between the tube body 11 and the electrical connection column 3, in this embodiment, an auxiliary groove 113 is further provided on the tube body 11, and a sealing rubber ring 33 matching the auxiliary groove is provided on the electrical connection column 3. The auxiliary groove 113 can be provided at both ends of the electrical connection column 3, or only at one end close to the first rubber sleeve 114 according to the sealing condition of the connection nut 7.

[0032] In order to achieve the third level of sealing, a sealing groove is provided at one end of the electrical connection column 3 away from the male pin 4 or the female plug 5. The sealing groove is provided in a round shape, and a sealing gasket 32 ​​is provided in the sealing groove. In this way, the cable first passes through the sealing gasket 32 ​​and then enters the incoming blind hole 31, thereby achieving another level of sealing.

[0033] Considering that if the first rubber sleeve 114 and the second rubber sleeve 37 are arranged in a tubular shape and they need to fit the cable, it is not conducive to the cable passing through. Therefore, in this embodiment, the first rubber sleeve 114 and the second rubber sleeve 37 are arranged in a trumpet shape. In this way, only one locking opening is needed to meet the sealing requirements without affecting the threading.

[0034] Through the above-mentioned settings, three-level sealing is effectively achieved. At the same time, the entire structure adopts a threaded connection method to facilitate construction.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
