[0023] 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.

[0024] Reference Figures 1-5 An insulating protection structure for the outer shell of a power distribution terminal includes an insulating protection component 1, wherein the components within the insulating protection component 1 are all made of one of the insulating materials such as polyphenylene sulfide, fiberglass, and SMC plastic.

[0025] The insulating protection assembly 1 includes a rear plate 101. A mounting frame 102 is fixed to one side of the rear plate 101 by bolts. A first sealing gasket 104 is provided between the mounting frame 102 and the rear plate 101. The first sealing gasket 104 is made of rubber and fills the gap between the two to prevent dust and moisture from entering the housing and to prevent internal components from getting damp and short-circuiting.

[0026] The other side of the mounting frame 102 is integrally formed with a rear shell 103. One side of the rear shell 103 is connected to a front shell 106 via a hinge. One side of the outer wall of the front shell 106 is provided with a fixing component 2.

[0027] A support frame 105 is bolted between the inner walls of the rear shell 103 and the inner wall of the front shell 106 is bolted to a pressure frame 107. A second sealing gasket 108 is bonded to one side of the pressure frame 107 and the second sealing gasket 108 is in contact with the support frame 105.

[0028] When the front shell 106 is closed, the second sealing gasket 108 is compressed, forming a sealing barrier between the front shell 106 and the rear shell 103, further enhancing the dustproof and waterproof capabilities of the shell. At the same time, the insulation of the second sealing gasket 108 can also help improve the overall insulation effect.

[0029] The fixing component 2 includes a limiting seat 201, which is welded to one side of the outer wall of the front housing 106.

[0030] A support seat 202 is welded to one side of the outer wall of the rear shell 103. A threaded rod 203 is rotatably connected between the inner walls of the two sides of the support seat 202. One end of the threaded rod 203 is engaged with the limiting seat 201. A connecting nut 204 and a fastening nut 205 are threadedly connected to the outer wall of the threaded rod 203. The connecting nut 204 and the fastening nut 205 are located on both sides of the limiting seat 201. The threaded rod 203 is rotated to engage with the limiting seat 201. Then the connecting nut 204 and the fastening nut 205 are tightened. The two nuts clamp from both sides of the limiting seat 201, firmly fixing the front shell 106 and the rear shell 103.

[0031] Two sets of wire fixing assemblies 3 are provided on one side of the rear plate 101. The wire fixing assembly 3 includes a fixing seat 301, which is fixed to one side of the rear plate 101 by bolts. A card seat 302 is rotatably connected to one side of the fixing seat 301 by a pin. Both the fixing seat 301 and the card seat 302 are provided with wire grooves 303. A connecting screw 305 is inserted into one side of the card seat 302. One end of the connecting screw 305 is threaded to the fixing seat 301. The connection wire of the power distribution terminal is placed in the wire groove 303 of the fixing seat 301. The card seat 302 is rotated to cover the wire. Then the connecting screw 305 is used to lock the card seat 302 and the fixing seat 301.

[0032] A rubber pad 304 is bonded inside the wire trough 303. The rubber pad 304 increases the friction between the wire and the wire to prevent the wire from sliding. On the other hand, it can prevent the wire from directly contacting the metal material, thus providing insulation protection. At the same time, it can buffer the pressure of external forces on the wire and prevent the wire sheath from being damaged, which could lead to leakage.

[0033] The bottom of the mounting frame 102 is provided with multiple through holes 4 so that the connection wires of the power distribution terminal can enter the mounting frame 102 through the through holes 4. The through holes 4 can also be equipped with rubber sealing rings according to the wire diameter to further enhance the sealing between the wire and the hole wall and prevent moisture and dust from entering through the hole gaps.

[0034] The bottom of the rear shell 103 is sealed with a heat sink 5, and the bottom end of the heat sink 5 is fitted with a dustproof mesh 6 to prevent dust from entering the interior of the shell through the heat sink 5, thus avoiding dust accumulation on the terminal components that may affect heat dissipation or cause a short circuit.

[0035] The working principle of this embodiment is as follows: In use, the distribution box is fixed to one side of the rear plate 101 with bolts. Then, the connecting wires in the distribution box enter the interior of the insulation protection component 1 through the through hole 4. The connecting wires in the distribution box are then placed into the wire groove 303 of the fixing seat 301. Then, the card holder 302 is rotated to cover the wires. The card holder 302 is then locked to the fixing seat 301 with the connecting screw 305 to fix the connecting wires. Then, the front shell 106 is closed. Then, the threaded rod 203 is turned and inserted into the limiting seat 201. Then, the connecting nut 204 and the fastening nut 205 are tightened to lock the front shell 106 and the rear shell 103. At the same time, the second sealing gasket 108 contacts the support frame 105 to seal the front shell 106 and the rear shell 103, thereby further improving the insulation.

[0036] The heat generated by the distribution box during operation is discharged from the heat sink 5, and dust is prevented from entering the casing, thus avoiding dust accumulation on the terminal components that may affect heat dissipation or cause short circuits.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
