The two square end faces of the housing 101 are divided into an upper bottom and a lower bottom, and the four rectangular faces of the housing 101 are side walls thereof.

Referring to fig. 3, the housing 101 is a shell structure, i.e., the space inside is a receiving cavity 102. The side wall of the housing 101 is formed with a through hole 103 communicating with the receiving cavity 102. The through hole 103 is a kidney-shaped hole, and the length direction thereof is parallel to the long side of the side wall where the through hole is located. This embodiment is suitable for waterproof sealing of the wire joint 301 of the second connection manner described in the related art. The wire connector 301, after connecting the two wires 300, passes through the through hole 103 and is placed in the housing cavity 102 of the casing 101, it being noted that: the conductive portion of the wire 300 that is stripped is required to be entirely disposed within the receiving cavity 102. And then, injecting the electronic pouring sealant into the accommodating cavity 102 from the through hole 103 until the accommodating cavity 102 is filled with the electronic pouring sealant, and immersing the wire connector 301 in the electronic pouring sealant.

The casing 101 has an elongated regular hexagonal prism shape, and in another embodiment, may have another regular prism shape such as a regular triangular prism or a regular quadrangular prism, or may have a cylindrical shape. The regular polygonal surface or the round surface on the housing 101 is the end surface thereof, and the other surfaces are the side walls thereof.

Referring to fig. 4, the housing 101 is a shell structure, and the space inside is a receiving cavity 102. The side wall of the housing 101 is provided with a glue injection vent hole 104 communicated with the accommodating cavity 102, and the glue injection vent hole 104 is used for injecting electronic pouring glue into the accommodating cavity 102. Both ends of the housing 101 in the length direction are provided with through holes 103 communicated with the accommodating cavity 102. The through hole 103 is located at the middle position of the two end faces of the housing 101.

Referring to fig. 4, since the housing 101 is in a long strip shape and the wire through holes 103 are located at two ends of the housing 101 in the length direction, the wires 300 need to enter the accommodating cavity 102 along the length direction of the housing 101, so that the wire connectors 301 of the two wires 300 are located at the middle position of the accommodating cavity 102 in the length direction, and therefore, a longer distance exists between the wire connectors 301 and the wire through holes 103, so that the wire connectors 301 are further away from the environment outside the waterproof junction box, and the waterproof effect of the waterproof junction box is improved. This embodiment is suitable for waterproof sealing of the wire joint 301 of the first connection manner described in the related art.

Because the housing 101 is regular prism-shaped or cylindrical, and the through-hole 103 is located in the middle of the two end faces of the housing 101, after the accommodating cavity 102 is filled with the electronic potting adhesive, the thickness of the electronic potting adhesive wrapped outside the wire connector 301 is more uniform, and the waterproof effect of the waterproof junction box is improved.

The hinge assembly 108 may also take other forms of hinge structures, such as a hinge.

In the second embodiment of the present application, a waterproof junction box is implemented according to the following principle: the two half shells are rotated in opposite directions to open the housing 101. The ends of two wires 300 extend through the through hole 103 into different half shells and then the two wires 300 are wound to form a wire connector 301. After the wiring of the electric wires 300 is completed, the two half shells are rotated in opposite directions, thereby closing the housing 101. And finally, injecting the electronic pouring sealant into the accommodating cavity 102 from the glue injection exhaust hole 104 until the accommodating cavity 102 is filled with the electronic pouring sealant, and wrapping the wire connector 301 after the electronic pouring sealant is solidified, so that the waterproof effect at the wire connector 301 is improved.

Referring to fig. 7, a waterproof junction box is different from the second embodiment in that: the division plane is parallel to the longitudinal direction of the casing 101. The volume of the second half shell 106 is larger than that of the first half shell 105, and the through hole 103 is opened in both end faces in the longitudinal direction of the second half shell 106. The glue injection exhaust hole 104 is opened in the sidewall of the first half-shell 105. Referring to fig. 7, in this example, the hinge assembly 108 is located on a side wall of the casing 101 (a side wall where a long side of the casing 101 is located), and a hinge axis of the hinge assembly 108 is parallel to a length direction of the casing 101. The specific connection structure of the hinge assembly 108 is as follows:

referring to fig. 7 and 8, the plugging rod 109 is fixedly connected to a side wall of the first half casing 105 (i.e. a side wall where a long side of the first half casing 105 is located), and the plugging rod 109 is parallel to the length direction of the casing 101. The hinge base 110 is fixedly connected to a side wall of the second housing half 106 (i.e., a side wall on which the long side of the second housing half 106 is located). The plug rod 109 is rotatably connected to the hinge base 110 by being inserted into the hinge opening 129, so that the two half shells are rotatably connected to each other.

Two wires 300 are respectively threaded into the second half shell 106 from two different wire through holes 103, and then the two wires 300 are wound to form a wire connector 301. After the wiring of the electric wires 300 is completed, the two half shells are rotated in opposite directions, thereby closing the housing 101. And finally, injecting the electronic pouring sealant into the accommodating cavity 102 from the glue injection exhaust hole 104 until the accommodating cavity 102 is filled with the electronic pouring sealant, and wrapping the wire connector 301 after the electronic pouring sealant is solidified, so that the waterproof effect at the wire connector 301 is improved.

Both ends of the shell 101 are coaxially provided with through wire holes 103 communicated with the accommodating cavity 102. The electric wire 300 enters the receiving cavity 102 through the through hole 103. The arrangement makes the housing 101 in a shuttle shape, and the contact positions of both ends of the housing and the electric wires 300 are streamline, so that the insulating tape can be conveniently wound at the connection position of the housing 101 and the electric wires 300. The insulating tape is wound from the housing 101 to a portion of the electric wire 300 outside the housing 101, so that the electric wire 300 and the housing 101 are fixed by the insulating tape, and the insulating tape can seal a gap between the inner wall of the through hole 103 and the outer wall of the electric wire 300, thereby improving waterproof performance.

Referring to fig. 11, circular truncated grooves 111 are coaxially formed at both ends of the circular truncated cone shape of the housing 101, and the end of the housing 101 is cut according to the truncated grooves 111, so that the diameter of the through-wire groove 114 can be increased to be suitable for electric wires 300 having different diameters. The number of the breaking grooves 111 is not limited, but is at least greater than one, and in this example, there are three breaking grooves 111 at both ends of the housing 101.

Referring to fig. 13 and 14, a plug 205 for plugging the glue injection exhaust hole 104 is connected to the housing 101. After the electronic pouring sealant is cooled, the plug 205 is used for sealing the glue injection exhaust hole 104, so that water is reduced from entering the shell 101, and the waterproof performance of the waterproof junction box is further improved. In this embodiment, the plug 205 is fixedly connected to the housing 101 by interference fit with the communication port 113.
