Description

TECHNICAL FIELD

[0001] The utility model relates to switch panel structure class technical field, concretely relates to wiring seat of good waterproofness. BACKGROUND

[0002] The electrical accessory waterproof product mainly has two categories of surface-mounted type and concealed type. The surface-mounted type is divided into two waterproof modes of panel type + base "knocking hole" type and "waterproof cover" type + base "wire hole" type. The concealed type is divided into two waterproof modes of panel type and "waterproof cover" type. The waterproof main body of the panel type is on the panel, and the waterproof function is mainly realized on the panel. When the waterproof box is installed, the base "knocking hole" type knocks off the middle material of the selected wire hole, exposes the standard wire hole reserved by the product, and standard installation can be carried out. The waterproof cover type is used as the waterproof function main body, and the product is installed in the waterproof cover.

[0003] With the increasing living standards of people, it is necessary to install a 25A wiring seat with an IP25 protection level or above in the bathroom. The existing wiring panel product has few reinforcing ribs on the back of the panel, and the panel is prone to deformation after installation, which causes the four corners to be raised, thereby affecting the waterproof function. The waterproof of the existing panel around is mostly realized by using rubber strips, but in actual use, most bathrooms will be tiled, and there are gaps between adjacent tiles. Many times, the bottom shell is installed between two tiles, and sometimes it is even installed at the junction of four tiles. Because of the gap between the tiles, the hardness of the rubber strip is not soft enough, so that the waterproof rubber ring of the panel cannot be attached to the tile gap, thereby affecting the waterproof effect. UTILITY MODEL CONTENTS

[0004] In view of the above technical problems, the utility model provides a wiring seat with good waterproofness.

[0005] To solve the above technical problems, the technical scheme provided by the utility model is: a wiring seat with good waterproofness, comprising a wiring panel, a base assembly is arranged on the back of the wiring panel, a wiring hole is arranged on the side of the wiring panel and communicated with the base assembly, the front of the wiring panel is an arc surface with a high middle and a low periphery, honeycomb nest ribs are uniformly arranged on the back of the wiring panel, a sealing groove is arranged on the opening end of the side wall around the back of the wiring panel, and foamed silica gel waterproof rings are filled in the sealing groove.

[0006] Further, in the wiring holder with good waterproof performance, the cross section of the foamed silica gel waterproof ring is in inverted T-shaped structure. The hardness of the foamed silica gel waterproof ring is 0. The waterproof ring in the prior art is mostly realized by using rubber strip. Since the rubber strip is relatively hard, if the installation base is installed between two ceramic tiles or at the joint of four ceramic tiles, the waterproof ring cannot be attached to the gap between the ceramic tiles due to the insufficient softness of the rubber strip, thereby affecting the waterproof effect. The inverted T-shaped waterproof ring is adopted, and the foamed silica gel material with hardness of 0 is selected. Under the installation torque of 6 kg, the foamed silica gel can be completely attached to the gap of the wall surface, thereby preventing water from entering the base.

[0007] The wiring hole is further provided with an incoming wire port waterproof ring and a wire locking nut from inside to outside. The wiring panel is provided with an oval screw mounting hole for mounting screws, and the mounting screw is provided with an "O" type waterproof ring. The "O" type waterproof ring can not only adjust the appearance of the panel up and down during installation, but also solve the problem of product waterproof after the loss or loosening of the existing screw cap or the missing of the screw cap during installation.

[0008] The opening of the screw mounting hole is provided with a screw cap, and the back of the screw cap is provided with an oval column. The length and width of the oval column are both 0.15-0.2 mm larger than the oval screw mounting hole. The screw cap is in interference fit with the mounting hole of the panel, and the waterproof effect of the screw cap is ensured.

[0009] Compared with the prior art, the wiring holder with good waterproof performance comprises a wiring panel, a base assembly is arranged on the back of the wiring panel, and a wiring hole is arranged on the side of the wiring panel and communicated with the base assembly. The front of the wiring panel is an arc surface with a high middle and a low periphery. The back of the wiring panel is also provided with honeycomb nest ribs. The opening end of the side wall of the back of the wiring panel is provided with a sealing groove, and the sealing groove is filled with a foamed silica gel waterproof ring. The panel of the existing wiring holder is prone to deformation after normal installation, which causes the four corners of the edge to be raised and affects the waterproof function. The front of the panel of the utility model is provided with an arc surface structure, and the back is provided with a honeycomb nest structure to enhance the strength of the panel. The wiring panel is not obviously deformed under the installation torque of 12 kg. Compared with the prior art, the waterproof safety of the wiring holder product is enhanced, and the product has multiple waterproof functions. Even if two screw caps are lost or missed, the product can still meet the waterproof requirement of IEC60529:2013 IP55. BRIEF DESCRIPTION OF DRAWINGS

[0018] In order to facilitate the person skilled in the art to understand, the utility model will be further described in detail in conjunction with the drawings and embodiments.

[0019] As Figures 1-7 A wiring seat with good waterproofness, comprising a wiring panel, a base assembly 1 is arranged on the back of the wiring panel, a wiring hole 2 communicating with the base assembly is arranged on the side of the wiring panel, the front of the wiring panel is an arc surface 3 with a middle high and a periphery low, honeycomb ribs 4 are evenly arranged on the back of the wiring panel, a sealing groove 5 is arranged on the opening end of the side wall of the back of the wiring panel, and a foamed silica gel waterproof ring 6 is filled in the sealing groove 5. The cross section of the foamed silica gel waterproof ring is in inverted T-shaped structure. The hardness of the foamed silica gel waterproof ring is 0. The wiring hole is further provided with a wiring inlet waterproof ring 7 and a wire locking nut 8 from inside to outside. An oval screw mounting hole 9 for mounting a screw is arranged on the wiring panel, and an "O" type waterproof ring 10 is arranged at the screw mounting position. A screw cap 11 is arranged at the opening of the screw mounting hole, the back of the screw cap is provided with an elliptic column, and the length and width dimensions of the elliptic column are all 0.15-0.2mm larger than those of the oval screw mounting hole.

[0020] The front face of the wiring panel of the embodiment adopts an arc face structure, and the back face adopts a honeycomb nest structure to enhance the strength of the panel, so that the wiring panel has no obvious deformation under a 12kg installation torsion. The inverted T-shaped waterproof ring uses a head platform to increase the contact area of the rubber strip with the wall surface, and the waterproof ring is slightly higher than the panel, so that the rubber strip expands under pressure and fills the waterproof groove of the panel to block water from entering the product interior. An "O"-shaped waterproof ring is arranged at the installation screw position. This not only ensures that the user can adjust the appearance of the panel up and down, but also solves the problem of product waterproofing after the loss or loosening or missing of the screw cap. The opening of the installation screw hole is provided with a screw cap, and the back of the screw cap is provided with an oval column, the length and width of the oval column are both larger than the oval installation hole by 0.15-0.2mm. The screw cap is in interference fit after being installed on the panel, the length and width of the oval column of the screw cap are both larger than the oval installation hole by 0.15-0.2mm, so as to ensure the waterproof effect of the screw cap. Therefore, the size of the panel installation screw hole can be designed as an oval shape with a length of 4.6mm and a width of 3.80mm, so as to ensure that the product meets the IP55 waterproof function, and the customer can still adjust the panel up and down through the oval hole to align the panel left and right. The head size of the M3.5 installation screw is designed as a diameter of 6.3mm. As long as the outer diameter of the "O"-shaped waterproof ring is larger than the size of the installation screw head by >5.8mm, the "O"-shaped waterproof ring covers the entire installation hole, so as to achieve the waterproof function. According to the general "O"-shaped ring standard of GB 3452.1-92, the "O"-shaped ring with an inner diameter of 2.8mm and an outer diameter of 6.4mm or an inner diameter of 3.15mm and an outer diameter of 6.75mm can also meet the requirements. The embodiment enhances the waterproof safety of the wiring seat product, so that the product has multiple waterproof functions. Even if two screw caps are lost or missing, the product can still meet the IP55 waterproof requirement.
