Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of cable connectors, and in particular to a moisture-proof and humidity-proof cable connector. Background Art
[0002] Due to the high density of the moisture-proof and moisture-proof power cable protective shell, the heating of the cable is more serious during use. Then, the processing methods of existing cables are mostly the same. The outer wall adopts an insulating layer, and the heat is difficult to dissipate. However, as the temperature of the cable continues to rise, its resistivity will become higher and higher, resulting in an increase in power loss during the power transmission process of the cable. However, when the cable is connected and installed, the joint is indispensable, so when the cable is connected, the crimping between the cable and the cable joint is more complicated and difficult. At the same time, it is very easy to oxidize at the connecting line end. If the crimping between the cable joint and the cable is not in place, with the later use process, the core body is affected by heat and expands and contracts, which will cause a connection gap between the terminal and the cable. Although heat shrink tubing is often wrapped when connecting the terminals, the heat shrink tubing can only shrink. If the cable expands and contracts multiple times, there will be a gap in the connection between the heat shrink tubing and the cable. At this time, the temperature of the connecting line end will rise after oxidation, especially for flat cables, which have higher requirements for pressing than flat cables. Summary of the invention
[0003] The technical solution of the present invention aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology. The embodiment of the present invention provides a moisture-proof and humidity-proof cable connector to solve the existing technical problem.
[0004] The embodiment of the present invention adopts the following technical solution: a moisture-proof and humidity-proof cable connector, comprising a connector for connecting cables, the connector comprising a male connection component and a female connection component, the female connection component being divided into an inner pasting layer, a foam layer and a protective layer from the inside to the outside, an extrusion groove being provided on the outside of the female connection component, and a clamping block being provided on the outside of the protective layer.
[0005] Furthermore, the cross section of the female connection component is L-shaped.
[0006] Furthermore, the inner layer is made of polyvinyl chloride or cross-linked polyethylene, the protective layer is made of soft resin material, and the foam layer is made of polyurethane material.
[0007] Furthermore, the male connection component includes a positioning ring, a deformable ring is connected inside the positioning ring, a memory alloy spring is arranged inside the deformable ring, a matching sleeve is arranged at the end of the deformable ring, a connecting sleeve is arranged on one side of the matching sleeve, a sealing ring is arranged between the matching sleeve and the connecting sleeve, an expandable hot-melt rubber ring is arranged inside the matching sleeve, and the matching sleeve and the connecting sleeve are connected by an elastic sleeve.
[0008] Furthermore, the positioning collar is made of elastic material and is in a trumpet shape.
[0009] Furthermore, the upper surface of the extrusion block is a curved surface, and the extrusion block is made of a plastic elastic material.
[0010] Furthermore, the positioning collar is provided with a clamping groove which is matched with the clamping block, and the protruding portion of the clamping block is made of elastic material.
[0011] Furthermore, the outer diameter of the matching sleeve is larger than the outer diameter of the connecting sleeve.
[0012] Compared with the prior art, the beneficial effects of the present invention are: First, add a layer of foam sponge at the connection between the connector and the cable. First, use the foam sponge's ability to absorb moisture. When the cable is running at high temperature, the water particles in the air are converted into water vapor and penetrate into the connection. At this time, the foam sponge can absorb the water vapor. At the same time, the foam sponge expands after absorbing water, resulting in a reduction in the gap between the connectors, thus preventing subsequent continuous water vapor penetration. Secondly, the foam sponge layer itself has foam gaps. When the battery core generates a lot of heat, the polyurethane foam will expand, and the gaps will increase. The air heat will directly contact the armor layer through the gaps, thereby accelerating its heat dissipation effect. When the outside temperature is low, insulation is required. At this time, the gaps will become smaller, thereby reducing air exchange and making the heat dissipation effect of the cable worse. In other words, the cable can be insulated, thereby reducing the impact of temperature on the cable, resulting in changes in resistivity and affecting its power transmission. Thirdly, by utilizing the cooperation between the various parts of the connector, when thermal expansion occurs, the hot melt adhesive inside the hot melt adhesive ring dissolves and turns into a molten state, and the thermal expansion and contraction material is reset, prompting the connector to move toward the joint, limiting the reset of the collar, canceling the extrusion effect of the foam material, and reducing the mutual resistance caused by the lateral expansion of the material. At the same time, since the hot melt adhesive is transformed into a molten state, it will not cause resistance to the joint. However, during the initial installation, since the molten adhesive is in a fixed state, the joint can be fixed and guided through the connector when installing the connector, so that the connection between the foam material and the connector is tighter; In summary, when the cable is connected through the connector, firstly, the phenomenon of temperature rise caused by water vapor penetrating into the interface due to the existence of the incision of the cable is reduced. At the same time, when the connection is made using the connecting mechanism, the shape can be adaptively changed to address the heating problem of the cable, thereby improving the heat dissipation effect. At the same time, when the temperature is low, the temperature of the connection will be guaranteed to avoid excessive cable flow loss due to too low temperature. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0021] Combine the following Figures 1 to 4 As shown, an embodiment of the present invention provides a moisture-proof and humidity-proof cable connector, including a connector for connecting cables, the connector including a male connection component 1 and a female connection component 2, the female connection component 2 being divided into an inner pasting layer 24, a foam layer 22 and a protective layer 21 from the inside to the outside, an extrusion groove 23 is provided on the outside of the female connection component 2, and a clamping block 12 is provided on the outside of the protective layer 21.
[0022] During operation, when the cable is connected through this connector, the phenomenon of temperature rise caused by water vapor penetrating into the interface due to the existence of the incision of the cable is first reduced. At the same time, when the connection is made using the connecting mechanism, the shape can be adaptively changed to address the heating problem of the cable, thereby improving the heat dissipation effect. At the same time, when the temperature is low, the temperature of the connection will be guaranteed to avoid excessive cable flow loss due to too low temperature.
[0023] Specifically, the cross section of the female connection component 2 is L-shaped.
[0024] During operation, the outermost layer of the female connection assembly 2 can be connected to the clamping block 12 .
[0025] Specifically, the inner layer 24 is made of polyvinyl chloride or cross-linked polyethylene, the protective layer 21 is made of soft resin material, and the foam layer 22 is made of polyurethane material.
[0026] Specifically, the male connection component 1 includes a positioning ring 13, a deformable ring 14 is connected to the positioning ring 13, a memory alloy spring is arranged in the deformable ring 14, a matching sleeve 18 is arranged at the end of the deformable ring 14, a connecting sleeve 17 is arranged on one side of the matching sleeve 18, a sealing ring 16 is arranged between the matching sleeve 18 and the connecting sleeve 17, an expandable hot-melt adhesive ring 15 is arranged in the matching sleeve 18, and the matching sleeve 18 and the connecting sleeve 17 are connected by an elastic sleeve.
[0027] Specifically, the positioning collar 13 is made of elastic material and is in a trumpet shape.
[0028] During operation, since the positioning sleeve is made of elastic material, it can be connected to cables with different outer diameters, and since it is in a bell-mouth shape, it is easier to adapt to different cables and ensure the installation effect.
[0029] Specifically, the upper surface of the extrusion block 11 is a curved surface, and the extrusion block 11 is made of plastic elastic material.
[0030] During operation, since the upper surface of the extrusion block 11 is an arc surface, when subjected to a resistance effect, the position of the extrusion block 11 may be deformed and deflected.
[0031] Specifically, the positioning collar 13 is provided with a clamping groove that cooperates with the clamping block 12 , and the protruding portion of the clamping block 12 is made of elastic material.
[0032] During operation, since the protruding portion of the clamping block 12 is made of elastic material, when the clamping slot and the clamping block 12 are connected, the clamping block 12 can be inserted into the clamping slot, and the clamping block 12 can also play a role in position limitation.
[0033] Specifically, the outer diameter of the matching sleeve 18 is greater than the outer diameter of the connecting sleeve 17 .
[0034] Working principle: When in use, connect the male component 1 and the female component 2 to the two groups of cables respectively, and then connect the male component 1 to the female component 2. When connecting, dock the male component 1 and the female component 2. At this time, the clamping block 12 on the female component 2 is inserted into the clamping groove on the male component 1, so as to achieve the connection effect between the female component 2 and the male component 1. As for the male component 1 and the female component 2, they can be connected to the corresponding cables through clamps in turn. During use, the polyurethane foam itself has foam gaps. When the heat generated by the battery core is relatively large, the polyurethane foam will expand, and the gap will increase. The air heat will directly contact the armor layer through the gap, thereby accelerating its heat dissipation effect. When the outside temperature is low, insulation is required. At this time, the gap will become smaller, thereby reducing air exchange, making the heat dissipation effect of the cable worse. In other words, the cable can be insulated, thereby reducing the influence of temperature on the cable, resulting in changes in resistivity. Affects its power transmission. Secondly, when the cable is in a high-temperature operation state, the water particles in the air are converted into water vapor and penetrate into the connection. At this time, the foam sponge can absorb the water vapor. At the same time, the foam sponge expands after absorbing water, resulting in a reduction in the gap between the connectors to avoid subsequent continuous water vapor penetration. At the same time, when thermal expansion occurs, the memory alloy spring in the deformation ring 14 expands and contracts, causing the positioning ring 13 to move. At this time, the positioning ring 13 is displaced, but because the positioning ring 13 and the connecting sleeve 17 are actually movably connected, the displacement of the positioning ring 13 will not drive the connecting sleeve 17 to move, thereby ensuring the mobility of the ring and the connectivity between the cables. When the positioning ring 13 is movable, it will drive the extrusion block 11 to move synchronously. At this time, the extrusion force of the extrusion block 11 on the foam layer 22 is reduced, resulting in a change in the sealing effect of the foam layer 22. At this time, the heated gas can overflow through the holes in the foam layer 22 to achieve the effect of heat dissipation. When the cable is connected through the connector, firstly, the phenomenon of temperature rise caused by water vapor penetrating into the interface due to the existence of the incision of the cable is reduced. At the same time, when the connection is made using the connecting mechanism, the shape can be adaptively changed to address the heating problem of the cable, thereby improving the heat dissipation effect. At the same time, when the temperature is low, the temperature of the connection can be guaranteed to avoid excessive cable flow loss due to too low temperature.
