Description

Technical Field

[0001] The present invention belongs to the technical field of bus duct tapping, and specifically relates to a tapping unit with an embedded rubber pad. Background Art

[0002] After 20 years of development, the dense busbar has gradually transformed from the early simple power supply function to high performance. As a low-voltage electrical product, it is very close to people's production and life. The safety and stability of the bus duct has naturally become the focus of the market. The liquid protection performance of the bus duct has always been a pain point in the industry. As an industrial product composed of a variety of sheet metal parts, how to improve the protection performance of its gaps has become the focus of major manufacturers.

[0003] Existing bus duct products are increasingly introducing the concept of heat dissipation, making the bus duct smaller and smaller, but for a long time, the protection level of dense bus ducts has not made significant progress. The most common sealing measure is to apply glue after the connector is installed. This operation can theoretically improve the protection performance, but whether the operator can strictly apply glue as required during the actual installation is a very big quality risk. Utility Model Content

[0004] In order to solve the above problems, this paper proposes a tapping unit with an embedded rubber pad. The tapping unit is provided in the middle of the upper surface of the busbar cover. The tapping unit includes a silicone sheet, a fixing bolt and a socket seat. The outer side of the bottom surface of the socket seat is provided with a silicone sheet. The silicone sheet is embedded on the surface of the busbar cover. Both sides of the silicone sheet are clamped and arranged above the side edge of the busbar cover. A plug-in box is provided on the upper surface of the silicone sheet in a downward pressing manner. A nylon block is provided at the bottom of the end surface of the plug-in box. Guide plates are provided on both sides of the bottom of the plug-in box. The length of the nylon block is the same as that of the silicone sheet. The inner width is the same, the bottom surface of the nylon block fits with the upper surface of the silicone sheet, the outer surface of the nylon block is flush with the end edge of the silicone sheet, the inner surface of the guide plate fits with the outer edge of the silicone sheet, and the integral rubber pad is covered around the socket. The guide plate is improved and a nylon block is added. When the plug-in box is inserted, the negative tolerance between the nylon block and the silicone sheet is matched to complete the front and rear sealing of the cover plate, and the rubber pad flange fits with the cover plate flange. After the plug-in box is plugged in, it is pressed on the cover plate as a whole, completing the comprehensive isolation around and above, and the liquid channel is completely isolated by the rubber pad. Thereby improving the overall protection performance of the plug-in box.

[0005] The shape of the busbar cover is a C-shaped groove cover with two right-angled sides bent. Both ends of the busbar cover are provided with mounting seats. A through hole is provided in the middle of the surface of the busbar cover, and a socket seat is above the through hole. A silicone sheet is provided on the outer side of the top surface of the through hole. The outer surface of the side of the busbar cover is provided with fixing bolts, and the fixing bolts are connected with the silicone sheet and the busbar cover in a through-type manner. By adding a silicone sheet to the outer side of the socket seat directly arranged above the busbar cover, the socket can form a deformation seal between the busbar cover and the junction box after installation. It is directly arranged on the outer side of the busbar cover, which not only simplifies installation but also reduces the modification cost.

[0006] The shape of the silicone sheet is a C-shaped grooved silicone sheet, with right-angled folds on both sides of the silicone sheet, and a evasion hole in the middle of the silicone sheet. The top edges of the right-angled folds are vertically downwardly provided with hook grooves on the outside, and the width between the right-angled folds on both sides is the same as the width of the inner side of the busbar cover. The inner side of the hook groove is connected to the edge top of the busbar cover by clamping, and the flange of the silicone sheet fits the flange of the cover. After the plug-in box is plugged in place, it is pressed on the cover as a whole, completing the comprehensive barrier around and above, and the liquid channel is completely isolated by the rubber pad. Thereby improving the overall protection performance of the plug-in part of the plug-in box.

[0007] The bottom surface of the plug-in box is connected to the socket seat in a plug-in manner, and guide plates are provided on both sides of the plug-in box in an outward-expanding manner. Positioning plates are provided vertically on the inner sides of both ends of the plug-in box. A nylon block is fixedly provided on the outer surface of the positioning plate. The nylon block is in the shape of a rectangular strip. The top surface of the nylon block fits the bottom surface of the plug-in box, and the two ends of the nylon block are connected to the inner side surface of the silicone sheet. The outer surface of the nylon block is flush with the end surface of the plug-in box, and is covered around the socket by an integral rubber pad. The guide plate is improved by adding a nylon block. When the plug-in box is plugged in, the negative tolerance between the nylon block and the silicone sheet is matched to complete the front and rear sealing of the cover.

[0008] Beneficial effects:

[0009] To minimize the reliance on the gluing process, the integrated rubber pad is used to cover the socket, and the guide plate is improved with a nylon block. When the plug-in box is plugged in, the negative tolerance between the nylon block and the silicone sheet is matched to complete the front and rear sealing of the cover, and the flange of the silicone sheet fits the flange of the cover. After the plug-in box is plugged in, it is pressed on the cover as a whole, completing the comprehensive barrier around and above, and the liquid channel is completely isolated by the rubber pad. This improves the overall protection performance of the plug-in box.

[0010] By adding a silicone sheet to the outside of the socket seat directly arranged above the busbar cover, the socket can form a deformation seal between the busbar cover and the junction box after installation. Directly setting it on the outside of the busbar cover not only simplifies installation but also reduces modification costs. BRIEF DESCRIPTION OF THE DRAWINGS
