Description

Technical Field

[0001] The invention relates to the field of electrical accessories, and in particular to a shielding sealing module and an electrical device. Background Art

[0002] As society pays more and more attention to the anti-electromagnetic radiation performance and protection performance of products, especially in the military, nuclear power and railway industries, users have clear shielding and sealing requirements for some housing products such as boxes, boxes and cabinets. The metal material of the housing is required to be continuous, able to block electromagnetic radiation from the outside from penetrating the housing, and prevent electromagnetic radiation inside the housing from emitting outward; at the same time, it has a protective function to prevent external dust and liquid from entering the inside of the housing, that is, the housing structure is a shielded and sealed structure. Due to the needs of operation, installation, or maintenance, these housings are usually unable to be made into independent, completely enclosed hollow housings. The power cable needs to pass through the housing to power the components inside the housing so that it can operate normally. At the same time, the signal cable also needs to pass through these housings to issue various instructions to the components inside the housing and communicate with the outside world. Where the above cables pass through the housing, the original continuity of the metal material of the housing will inevitably be destroyed, that is, the integrity of the electromagnetic shielding and protection functions of the housing will be destroyed. In order to maintain the shielding and protection functions of the housing, the mainstream practice in the industry is to install a shielding and sealing module where the cable passes through the housing so that the housing maintains the continuity and protection functions of the metal material. The mainstream module structures with shielding and sealing functions on the market are mainly divided into three forms. The first structure is the gland type. The first layer of rubber ring in the gland is used to seal the cable that passes through the gland, and the second layer of metal spring inside is used to conduct the shielding layer of the cable that passes through the gland. The biggest disadvantage of the gland type is the low cable installation density. Because a gland can only pass one cable, and a wrench is required to fix the gland, and the wrench requires a large lateral operating space, which limits the use of the gland in high-density cable occasions. The second structure is the wedge type. The first layer of soft material on the outside of the wedge structure is used to seal the cable that passes through the structure, and the second layer of conductive material on the inside is used to conduct the shielding layer of the cable that passes through the structure. The wedge-type shielding and sealing module is easy to install and has a high cable installation density, but because soft conductive materials are required between its main structure and the shell, box or cabinet to achieve the integrity of the shielding and sealing functions, only a low torque value can be used when fixing this structure, so it is only suitable for low-vibration occasions. The main structure of the wedge-type shielding and sealing module consists of two or more parts (mostly two or four parts on the market). During installation, the mating surfaces of these parts will slide against each other. In reality, there is no perfect manufacturing process. The sliding mating surfaces must be filled with viscous or semi-solid materials such as glue or lipids to achieve the sealing function. These materials are prone to aging and lose their sealing function. The third type is the compression type, which uses a specific compression block to compress the cable and the double-layer sealing block in a rigid frame. The place where the cable enters the structure is the first layer of ordinary rubber, and the place where the cable passes out of the structure is the second layer of conductive material, thereby achieving shielding and sealing functions.The compression-type shielding sealing structure has a high cable installation density and is firmly fixed. Due to the complex manufacturing process and high precision requirements, its cost and installation difficulty are relatively the highest among the above three shielding sealing structures. There are also some non-mainstream single-layer sealing module structures on the market, which are mainly used in cable sealing occasions and do not have the function of conducting the shielding layer in the cable. The several parts that constitute the structure in these modules are directly compressed together under the action of fasteners. There are the same problems between the sliding mating surfaces as the wedge-type structure, and the high-precision manufacturing process is required between the final compressed fitting surfaces to achieve precise matching between rigid components to achieve waterproof and other sealing functions. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art single-layer sealing module that does not have the cable shielding layer conduction function, there is sliding fit on the mating surfaces during module installation, high manufacturing precision requirements for rigid materials in the module, many types of materials in the module, poor flexibility in adapting to different cable outer diameters, high cost and difficulty in installation of the sealing and shielding module, and to provide a double-layer structured shielding sealing module and electrical device.

DETAILED DESCRIPTION

[0042] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0043] like Figure 1-7 As shown, this embodiment provides a shielding and sealing module 100, which includes: a first main body component 161 and a second main body component 162 that are relatively arranged in a first direction X1 and can be detached from each other, a first top plate 111 and a second top plate 112 that are relatively arranged in the first direction X1, a first bottom plate 121 and a second bottom plate 122 that are relatively arranged in the first direction X1, and a first sealing component 141 and a second sealing component 142 that are relatively arranged in a second direction X2 that is perpendicular to the first direction X1.

[0044] The first top plate 111 and the second top plate 112 are detachably connected to the top of the first main body member 161 and the top of the second main body member 162, respectively. The first bottom plate 121 and the second bottom plate 122 are detachably connected to the bottom of the first main body member 161 and the bottom of the second main body member 162, respectively.

[0045] An accommodating space 180 is defined between the first main body member 161 and the second main body member 162. The first top plate 111 and the second top plate 112 respectively surround the accommodating space 180 in a third direction X3, wherein the third direction X3 is perpendicular to the first direction X1 and the second direction X2. The first sealing member 141 and the second sealing member 142 respectively surround the accommodating space 180 in the second direction X2.

[0047] The shielding and sealing module 100 is divided into two detachable parts, so that only the two opposite parts need to be disassembled and assembled to insert and install the cable, which improves the convenience of installation. At the same time, the part where the cable is inserted is in a sealed accommodating space 180 surrounded by the first top plate 111, the second top plate 112, the first bottom plate 121, the second bottom plate 122, the first sealing component 141, the second sealing component 142, the first main component 161, the second main component 162 and the cable inserted into the first cable insertion hole 131, thereby ensuring the sealing and electromagnetic shielding of the cable. The main components are detachably connected to the top plate and the bottom plate, respectively, and cable insertion holes are set on the top plate and the bottom plate. In this way, the top plate and the bottom plate can be replaced according to different cable specifications, and there is no need to replace the entire shielding and sealing module 100, thereby reducing the cost of use.

[0048] In this embodiment, the first top plate 111 and the second top plate 112 respectively form half of the first cable insertion hole 131 on the surfaces opposite to each other; the first bottom plate 121 and the second bottom plate 122 respectively form half of the second cable insertion hole 132 on the surfaces opposite to each other.

After the first bottom plate 121 and the second bottom plate 122 are butted together, the first cable insertion hole 131 becomes a complete circular hole. Optionally, a part of a half hole can also be formed on the first bottom plate 121 or the second bottom plate 122, for example, 40% of the circular hole is formed on the first bottom plate 121, and 40% of the circular hole is also formed on the second bottom plate 122. After the first bottom plate 121 and the second bottom plate 122 are butted together, the sealing between the two is achieved by a sealing strip or other components therebetween.

[0064] In other embodiments, the clamping member may also be a clamp-shaped member that clamps the first body member 161 and the second body member 162 from the outside of the first body member 161 and the second body member 162 respectively.

[0065] The shielding and sealing module 100 further includes a third sealing strip 153 , which is disposed at the bottom of the bottom plate along an edge of the bottom plate formed by the first bottom plate 121 and the second bottom plate 122 .

[0068] The following briefly describes the method of using the shielding and sealing module 100.

[0069] The first top plate 111 and the second top plate 112 are first fixed to the first transverse top plate 1611 and the second transverse top plate 1621, respectively, and the first bottom plate 121 and the second bottom plate 122 are fixed to the first transverse bottom plate 1613 and the second transverse bottom plate 1623, respectively. The first sealing strip 151 and the second sealing strip 152 are fixed to the first top plate 111 and the second top plate 112, respectively, and the clamping parts, that is, the first threaded fastener 171 and the second threaded fastener 172 are loosened, so that the first top plate 111 and the second top plate 112 are separated from each other, and the first bottom plate 121 and the second bottom plate 122 are separated from each other. The cable is first stripped of a section of the annular insulation sheath, and passed through the first cable insertion hole 131 and the second cable insertion hole 132.

The third sealing strip 153 is embedded in the groove of the bottom plate. Finally, the shielding sealing module 100 is fixed to the housing containing the electrical components by fasteners such as screws or bolts provided on the bottom plate. Thus, the sealing function is achieved through the first cable insertion hole, and the shielding function is achieved through the second cable insertion hole.

[0071] This embodiment also provides an electrical device, which includes: a housing for accommodating electrical components and the above shielding and sealing module 100; the housing is provided with a wiring opening, and the bottom of the shielding and sealing module 100 is connected to and covers the wiring opening.
