Description

Technical Field

[0002] The cable threading plate is a threading structure with multiple holes that can firmly clamp the cables to prevent them from falling off or swinging. The holes are designed in various ways to accommodate cables of different diameters and types. Cable threading plates are widely used in the fields of electricity, communications, etc., and can improve the stability and reliability of power, communications and other systems.

[0003] In the prior art, cable threading plates are generally divided into pagoda-type threading plates and straight-through type threading plates, among which the straight-through type threading plates are divided into single-core straight-through type threading plates and multi-core straight-through type threading plates. However, the pagoda-type threading plate needs to cut the boss to achieve the threading function that adapts to the cable diameter, which will lead to problems such as poor waterproof sealing of the opening, insufficient structural rigidity, and poor installation performance. The single-core straight-through type only allows a single multi-core cable to pass through, and an opening larger than the wire diameter must be cut to facilitate threading, resulting in poor waterproof and airtightness, and only plays a role in insect prevention. The multi-core straight-through type threading plate only allows the cable core to pass through individually, and the forks are relatively open, which makes it more difficult to install the core with a larger bending radius. Like the single-core straight-through type, it has poor waterproof and airtightness and only plays a role in insect prevention.

[0004] Conventional cable entry plates have poor waterproof and airtightness, which can easily affect the performance and reliability of electrical equipment. Utility Model Content

[0040] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0041] like Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, a threading structure is provided, including: a threading plate 1, a sealing member 2 and a thread sleeve 3.

[0042] The threading plate 1 has an installation middle frame 11 and a sealing surface 12 located in the installation middle frame 11. The outer contour of the threading plate 1 can be rectangular, and the installation middle frame 11 for the cable to pass through is formed in the middle of the threading plate 1. In order to ensure that the threading plate 1 itself has a certain sealing performance, a sealing surface 12 is provided in the installation middle frame 11, and the sealing surface 12 can be cut to allow cables of different sizes to pass through.

[0043] The sealing member 2 has a connection portion 21 and a plurality of wire distribution sleeves 22. The connection portion 21 is connected to the installation middle frame 11 and fits with the sealing surface 12. One end of the wire distribution sleeve 22 forms a first inlet 221 at the end face of the connection portion 21, and the other end extends away from the connection portion 21 and shrinks to form a first outlet 222. The wire distribution sleeve 22 may be tapered. When installing cables, an inlet corresponding to the shape and position of the first inlet 221 may be cut out on the sealing surface 12. After the cables are inserted from the inlet, they pass through the first inlet 221 and the first outlet 222 in sequence. Since the first outlet 222 is in a shrinking shape, the inner wall of the first outlet 222 may fit closely with the outer wall of the cable, thereby forming a first seal. When the cable is a single-core cable, it may be inserted from one of the wire distribution sleeves 22. When the cable is a multi-core cable, it may be inserted from different wire distribution sleeves 22 in sequence.

[0044] One end of the wire combining sleeve 3 is connected to the end face of the connecting portion 21 to form a second inlet 31, and the other end extends in a direction away from the connecting portion 21 and is narrowed to form a second outlet 32. At least one branching sleeve 22 extends into the second inlet 31. After the cable extends out of the first outlet 222 of the branching sleeve 22, it directly enters the wire combining sleeve 3. The cable can extend out of the second outlet 32. Since the second outlet 32 ​​is narrowed, the second outlet 32 ​​can seal the single-core wire and bundle and seal the multi-core wires, thereby forming a second seal.

[0045] The threading structure provided by the utility model can be applied to electrical equipment that needs to be used for plugging cables, such as electrical connectors, power cabinets, and distribution boxes. The above two seals can greatly reduce the gap between the cable and the threading plate, improve the waterproof and airtightness of the threading plate, and ensure the performance and reliability of the electrical equipment.

[0046] In addition, the second inlet 31 of the wire junction sleeve 3 may further include a plurality of wire splitting sleeves 22 , for example, two or more, which can be flexibly arranged according to the number of multi-core wires.

[0047] In this embodiment, the sealing member 2 and the wire-binding sleeve 3 can be made of common elastic sealing materials, such as silicone. The connecting portion 21 of the sealing member 2 can be a sheet-like structure, and the connecting portion 21 can be bonded to the mounting middle frame 11 by gluing or hot melting. The wire-binding sleeve 3 can have a variety of sizes, so that the second inlet 31 of the wire-binding sleeve 3 can accommodate a single or multiple wire-binding sleeves 22, such as Figure 3 As shown, the second inlet 31 of the closing sleeve 3 accommodates three branching sleeves 22, and the multi-core wires passing through the three branching sleeves 22 can be extended together from the second outlet 32. The second inlet 31 of the closing sleeve 3 can also be bonded to the connecting portion 21 by gluing or hot melting, thereby improving the sealing between the closing sleeve 3 and the sealing member 2.

[0048] like Figure 3 As shown, in this embodiment, there is a first wire hole 223 with a gradually decreasing inner diameter between the first inlet 221 and the first outlet 222. The shape of the first wire hole 223 is similar to a funnel. The inner wall of the first wire hole 223 can guide the cable. After the cable is inserted into place, the gap in the first wire hole 223 can be filled with fireproof mud, thereby improving the protection level. There is a second wire hole 33 with a gradually decreasing inner diameter between the second inlet 31 and the second outlet 32. The shape of the second wire hole 33 is similar to a funnel. The second wire hole 33 can guide a single or multiple core wires, so that the core wires can pass through the second outlet 32 ​​smoothly.

[0049] like Figure 2 and Figure 3 As shown, in this embodiment, a plurality of wire splitting sleeves 22 are arranged at intervals on the end surface of the connecting portion 21 . Such an arrangement can facilitate wiring, and the gap between two adjacent connecting portions 21 facilitates bonding of the wire closing sleeve 3 to the connecting portion 21 .

[0050] like Figure 3 and Figure 4 As shown, in the present embodiment, an annular boss 111 is provided in the mounting middle frame 11, the edge of the sealing surface 12 is connected to the annular boss 111, the sealing surface 12 can be integrally formed with the annular boss 111, the edge of the connecting portion 21 is tightly fitted with the annular boss 111, and the annular boss 111 has a plane that contacts and cooperates with the connecting portion 21, thereby improving the stability and sealing of the connection between the connecting portion 21 and the mounting middle frame 11.

[0051] like Figure 2 and Figure 3As shown, in this embodiment, the outer side of the second inlet 31 of the wire sleeve 3 has an annular flange 34, and the annular flange 34 is tightly matched with the end surface of the connecting part 21. The annular flange 34 increases the contact area between the wire sleeve 3 and the connecting part 21, improves the connection strength and sealing between the wire sleeve 3 and the connecting part 21, and avoids the friction of the cable separating the wire sleeve 3 from the connecting part 21 when threading, and can also avoid the influence of gluing or hot melting on the permeability of the second inlet 31.

[0052] like Figure 2 and Figure 5 As shown, in this embodiment, the threading structure also includes a mounting plate 4, which is crimped with the threading plate 1, and the sealing member 2 is located between the mounting plate 4 and the threading plate 1. The mounting plate 4 has a through hole 41 that allows the wire combining sleeve 3 and multiple wire dividing sleeves 22 to pass through. The mounting plate 4 can be installed on the housing of the electrical equipment to facilitate the subsequent installation of the threading plate 1. The through hole 41 facilitates the passage of cables, and can avoid bending the wire combining sleeve 3 and the wire dividing sleeve 22, thereby avoiding bending of the cables.

[0053] For example, the mounting plate 4 can be installed on the connector housing 6, and the connector housing 6 has an opening for accommodating the mounting plate 4. Alternatively, one of the side walls of the connector housing 6 is constructed as the mounting plate 4, and the threading plate 1 can be installed on the mounting plate 4, thereby sealing the cables entering the connector housing 6.

[0054] like Figure 2 and Figure 4 As shown, in this embodiment, an annular groove 112 is provided on the end face of the threading plate 1 facing the mounting plate 4. The annular groove 112 is used to install a sealing ring. The annular groove 112 is formed on the end face of the mounting plate 4. The sealing ring is installed in the annular groove 112. When the threading plate 1 is installed on the mounting plate 4, the sealing ring is squeezed by the annular groove 112 and the mounting plate 4, thereby sealing the gap between the threading plate 1 and the mounting plate 4.

[0055] like Figure 5 , Figure 6 , Figure 7 , Figure 8 and Fig. 9 As shown, in the present embodiment, a plurality of positioning pins 42 are provided at the corners of the mounting plate 4, a plurality of positioning holes 13 corresponding to the positioning pins 42 are provided at the corners of the threading plate 1, and a guiding slope 131 is provided at one end of the positioning hole 13 close to the positioning pin. For example, four positioning pins 42 are respectively provided at the four corners of the mounting plate 4, and four positioning holes 13 are provided at the corresponding positions of the threading plate 1, and the positioning hole 13 has a guiding slope 131. When the threading plate 1 is installed, the positioning pin 42 can accurately enter the positioning hole 13 through the guiding slope 131, so that the threading plate 1 is installed on the mounting plate 4.

[0056] like Figure 5 , Figure 6 and Figure 7 As shown, in this embodiment, the threading plate 1 is provided with a first mounting hole 14, the mounting plate 4 is provided with a second mounting hole 43, the fastener 5 sequentially passes through the first mounting hole 14 and the second mounting hole 43, a plurality of first mounting holes 14 are arranged around and spaced at the edge of the threading plate 1, the positions and numbers of the plurality of second mounting holes 43 correspond to the first mounting holes 14, and a plurality of fasteners 5 sequentially pass through the corresponding first mounting holes 14 and the second mounting holes 43, thereby fixing the threading plate 1 on the mounting plate 4. The fastener 5 may be a self-tapping screw.

[0057] In this embodiment, the fastener 5 can be pre-installed in the first mounting hole 14. Then, after the positioning pin 42 is inserted into the positioning hole 13 and is in place, the fastener 5 can be aligned with the second mounting hole 43 and pre-installed by utilizing the properties of the self-tapping screw. After that, the fastener 5 can be tightened, which facilitates the installation of the threading plate 1.

[0058] like Figure 2 , Figure 4 and Fig. 9 As shown, in the present embodiment, the mounting plate 4 is a sheet metal part, and the mounting plate 4 is overmolded on the threading plate 1, and the edge of the threading plate 1 wraps the edge of the mounting plate 4. The threading plate 1 is made of silicone as a whole, and after the seal 2 and the wire sleeve 3 are bonded to the threading plate 1 by gluing or hot melting, the mounting plate 4 can be crimped to the outside of the seal 2 and the wire sleeve 3, and the mounting plate 4 is overmolded on the threading plate 1 by using the overmolding process, which is beneficial to improve the structural strength of the threading plate 1, and can also improve the sealing of the threading structure.

[0059] The end surface of the mounting plate 4 has a plurality of via holes 17 for allowing silicone to flow in. The plurality of via holes 17 increases the amount of silicone flowing in, which is beneficial to improving the connection strength between the mounting plate 4 and the threading plate 1 .

[0060] like Figure 2 , Figure 6 and Figure 7 As shown, in this embodiment, the branching sleeve 22 is located at the first end face of the sealing surface 12, and the second end face of the sealing surface 12 has a first ring 151 corresponding to the position of multiple branching sleeves 22. The outer ring size of the first ring 151 is the same as the size of the first inlet 221. The first ring 151 is used to indicate the cutting position. After determining the cable model, the sealing surface 12 can be cut accordingly to form an inlet to facilitate the insertion of the cable.

[0061] like Figure 2 , Figure 6 and Figure 7As shown, in this embodiment, the second end face of the sealing surface 12 is provided with a second ring 152 and a third ring 153, and the second ring 152 and the third ring 153 are arranged concentrically with the first ring 151 in the middle, and the sizes of the first ring 151, the second ring 152 and the third ring 153 increase successively, and the first ring 151, the second ring 152 and the third ring 153 can correspond to the diameters of cables of different models, and the second ring 152 and the third ring 153 are also used to indicate the cutting position.

[0062] like Figure 4 As shown, in this embodiment, the first ring 151 is formed in the shape of a groove on the second end face of the sealing surface 12, and similarly, the second ring 152 and the third ring 153 are also formed in the shape of a groove on the second end face of the sealing surface 12, thereby facilitating cutting.

[0063] The following will combine two specific application scenarios to illustrate the coordination between the cables and the threading structure mentioned above.

[0064] Application scenario 1

[0065] like Fig.10 , Fig.11 and Fig.12 As shown, when the cable is a multi-core cable 71, the multiple first rings 151 of the sealing surface 12 can be cut, so that the multi-core cable can be inserted into the corresponding branching sleeve 22 in sequence, for example, four cores are inserted into the corresponding branching sleeve 22 in sequence, and extend from different first outlets 222, then enter the closing sleeve 3, and then extend from the second outlet 32 ​​of the closing sleeve 3, and the branching sleeve 22 and the closing sleeve 3 form two seals for the cable. After the cable is inserted into place, the first wire hole 223 of the branching sleeve 22 can also be filled with fireproof mud to improve the protection level.

[0066] Application scenario 2

[0067] like Fig.13 , Fig.14 and Fig.15 As shown, when the cable is a single-core wire 72, the circular ring corresponding to the size of the sealing surface 12 can be cut open. Taking the third circular ring 153 as an example, the single-core wire can be inserted into the wire sleeve 3 and extended from the second outlet 32. Since the second outlet 32 ​​is a tapered design, the inner wall of the second outlet 32 ​​can fit tightly with the outer wall of the single-core wire, thereby achieving a sealing effect. The gap in the second wire hole 33 of the wire sleeve 3 can also be filled with fireproof mud to improve the protection level.

[0068] From the above description, it can be seen that the threading structure provided in the present application can meet the plug-in requirements of single-core wires or multi-core wires while ensuring sealing, and can be greatly adapted to a variety of application scenarios.

[0069] The present application also provides a connector, including the above-mentioned threading structure and a connector housing 6. The connection method and the use method of the connector housing 6 and the threading structure have been described in detail above and will not be repeated here.
