Description

Technical Field

[0001] The utility model relates to a terminal cap, in particular to a plug-in rubber insulated terminal cap, belonging to the technical field related to power insulation equipment. Background Art

[0002] The rubber insulated terminal cap is an insulation protection device widely used in the power system and electronic engineering. It is mainly used to protect cable ends, connectors, circuit boards, etc. from damage and prevent electrical contact. This terminal cap is usually made of rubber or other insulating materials, has good insulation performance and weather resistance, and can provide stable protection in various environments.

[0003] The rubber insulated terminal cap is internally provided with a threaded connector, and the threaded connector can screw together two or more terminal conductive parts, playing a role in connecting and protecting the terminals. Moreover, this connection method is relatively firm and can maintain the connection relationship unchanged under vibration or external force. However, because the ports of the rubber insulated terminal cap need to access different numbers of wire conductive ends, the open ends of the rubber insulated terminal cap are generally designed as ports with a larger diameter to facilitate the insertion and screwing of wires. However, after the wires are screwed together, gaps of different sizes are generated between the edge positions of the ports and the wires, and some larger particles of debris enter the rubber insulated terminal cap through these gaps, which will have a certain impact on the screwed wire conductive parts, and seriously may cause dangers such as short circuits or fires.

[0004] Therefore, it is urgent to improve the plug-in rubber insulated terminal cap to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a plug-in rubber insulated terminal cap. The terminal cap body is used to connect multiple wire conductive parts, and a shielding component is arranged on the terminal cap body. One part of the shielding component is connected to the opening part, and the other part is in a freely movable state. The movable end of the shielding component exerts its unique function on the wire. At this time, the gap between the wire and the opening part can be blocked. The shielding component adopts various implementation methods, and its main purpose is to make the gap between the wire and the opening part no longer exposed, so as to reduce the possibility of impurities entering the terminal cap body through this gap. By setting the shielding component, the position of the wire conductive part is effectively protected, and some dangerous situations caused by the entry of impurities are effectively avoided, strengthening the protection function and effect of the terminal cap body.

[0006] To achieve the above purpose, the main technical solutions adopted by the utility model include: a terminal cap body, and a threaded connector is arranged inside the terminal cap body, and the threaded connector is used for screwing and connecting a plurality of wire conductive ends;

[0007] An opening formed at one end of the terminal cap body;

[0008] A shielding assembly, which is disposed on the opening, and the shielding assembly is used to shield the gap between the edge of the opening and the wire.

[0009] Preferably, the shielding assembly includes an upper clamping member and a lower clamping member, and the upper clamping member and the lower clamping member are connected to each other by a fixing member and are jointly clamped on the opening.

[0010] Preferably, the fixing includes a through groove formed on the upper clamping member and a rotating plate rotatably connected to the lower clamping member. When the rotating plate passes through the through groove and rotates, the connection state between the upper clamping member and the lower clamping member is achieved.

[0011] Preferably, the fixing member includes a bolt member, and the upper clamping member and the lower clamping member are connected and fixed by the bolt member.

[0012] Preferably, the shielding assembly includes a grooved end cap clamped on the opening and a second grooved cap rotatably connected to the grooved end cap.

[0013] Preferably, the shielding assembly includes a heat shrinkable pipe member fixedly connected to one end of the opening.

Specific embodiments

[0026] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0027] As Figures 1-7As shown in the figure, the plug-in rubber insulation terminal cap provided in this embodiment includes a terminal cap body 1. A threaded connecting piece 2 is arranged inside the terminal cap body 1. The threaded connecting piece 2 is used for screwing and connecting the conductive ends of several electric wires. When the terminal cap body 1 is in use, remove the outer insulation protection layer of two or more electric wires (the electric wires are prior art, so they are not shown in the figure) and expose the internal conductive parts. Then insert the conductive parts together onto the threaded connecting piece 2 inside the terminal cap body 1. Then rotate the terminal cap body 1, and the conductive parts of the electric wires inside it will be screwed and twisted together, so that the conductive parts of different electric wires can be connected together. Among them, the threaded connecting piece 2 is a prior structural technical feature.

[0028] An opening 3 opened at one end of the terminal cap body 1, that is, the opening 3 is set according to the size and model of the terminal cap body 1. The diameter of its opening 3 is generally larger than the cross-sectional diameter of the position where the threaded connecting piece 2 is located. The purpose is to be able to insert the conductive part of the electric wire easily when inserting it, and it will not cause scratching to the conductive part.

[0029] A shielding component is arranged on the opening 3, and the shielding component is used to shield the gap between the edge of the opening 3 and the electric wire. When the conductive part of the electric wire is inserted into the threaded connecting piece 2 and screwed together, the shielding component can shield the gap between the electric wire and the opening 3, and does not affect the movement of the electric wire while shielding, thereby effectively reducing the entry of larger impurities into the terminal cap body 1.

[0030] Furthermore, as Figures 1-2 shown, the first implementation manner of the shielding component of the present utility model is that the shielding component includes an upper clamping piece 4 and a lower clamping piece 5. The upper clamping piece 4 and the lower clamping piece 5 are connected to each other through a fixing piece and are jointly clamped on the opening 3. When in use, place the upper clamping piece 4 and the lower clamping piece 5 on both sides of the opening 3 respectively, and then use the fixing piece to fixedly connect the upper clamping piece 4 and the lower clamping piece 5. And when fixedly connecting, the upper clamping piece 4 and the lower clamping piece 5 jointly clamp the opening 3 therein, realizing the connection state between the shielding component and the opening 3, and at this time the electric wire is in the slot 9 left in the middle of the upper clamping piece 4 and the lower clamping piece 5.

[0031] Among them, as Figure 1 shown, the first implementation manner of the fixing piece of the present utility model is that the fixing includes a through groove 602 opened on the upper clamping piece 4 and a rotating plate 601 rotatably connected to the lower clamping piece 5. When the upper clamping piece 4 and the lower clamping piece 5 are butted against each other, when the rotating plate 601 passes through the through groove 602 and rotates, at this time the rotating plate 601 presses the upper clamping plate and the lower clamping piece 5 to fit tightly together, realizing the connection state between the upper clamping piece 4 and the lower clamping piece 5.

[0032] Furthermore, as Figure 2As shown in the figure, the second embodiment of the fixing member of the present utility model is that the fixing member includes a bolt member 603. The upper clamping member 4 and the lower clamping member 5 are connected and fixed by the bolt member 603. By installing the bolt member 603 at both ends of the upper clamping member 4 and the lower clamping member 5, the upper clamping member 4 and the lower clamping member 5 can be fixed together, thereby realizing the shielding effect on the opening 3. Compared with the first embodiment of the fixing member, this embodiment has stronger stability, so that the upper clamping member 4 and the lower clamping member 5 will not easily break away from each other. However, the first embodiment of the fixing member is more time-saving in installation than the second embodiment.

[0033] Furthermore, as Figures 3-4 shown, the second embodiment of the shielding assembly of the present utility model is that the shielding assembly includes a grooved end cap 7 clamped in the opening 3 and a second groove cap 8 rotatably connected to the grooved end cap 7. The grooved end cap 7 and the rotating groove plate are respectively provided with slots 9 of the same size. When the two slots 9 are adjusted to the same position and communicated, the slot 9 at this time has the largest passing size. The conductive part of the wire is passed through the positions where the two slots 9 are located and screwed and connected in the threaded connector 2. Then the second groove cap 8 is rotated to deflect the position of the slot 9 formed in the second groove cap 8 until it is perpendicular to the slot 9 located on the grooved end cap 7. At this time, the positions on the two slots 9 will be blocked by the grooved end cap 7 and the second groove cap 8, so that the space size that can pass between the grooved end cap 7 and the second groove cap 8 becomes smaller. At this time, the wire will be squeezed in the space communicated here, thereby realizing the effect of shielding the gap between the opening 3 and the wire. This embodiment of the shielding assembly is more convenient to operate than the first embodiment, and there is no need to use a fixing member for fixed connection anymore.

[0034] Still further, as Figure 5 shown, the third embodiment of the shielding assembly of the present utility model is that the shielding assembly includes a heat-shrinkable pipe fitting 10 fixedly connected to one end of the opening 3. The conductive part of the wire passes through the inside of the heat-shrinkable pipe fitting 10 and is screwed and connected in the threaded connector 2. High temperature is applied to the heat-shrinkable pipe fitting 10. Under its characteristics, the heat-shrinkable pipe fitting 10 will undergo strong radial contraction under the influence of heating (such as from a hot air blower), thereby wrapping the wire located therein, so as to realize the effect of shielding the gap between the opening 3 and the wire. This embodiment of the shielding assembly has a more obvious effect compared with the second embodiment. This embodiment will make the contact between the shielding assembly and the wire closer, so that the effect of shielding the gap between the opening 3 and the wire is more obvious, and it is more beneficial to reduce the entry of impurities into the terminal cap body 1.

[0035] Still further, as Figures 6-7As shown in the figure, the fourth embodiment of the shielding component of the present utility model is that the shielding component includes a flexible hose member 11 fixedly connected to the opening 3 at one end. When not in use, the hose member 11 is placed on the terminal cap body 1. When in use, only need to manually toggle one end of the hose member 11 to gradually separate it from the support of the terminal cap body 1. When the hose member 11 is separated from the terminal cap body 1, the hose member 11 will exert its elastic property, and one end of the hose member 11 will contract on the wire, thereby wrapping the wire to shield the gap between the wire and the opening 3.

[0036] As Figures 1-7 shown in the figure, the principle of the plug-in rubber insulated terminal cap provided in this embodiment is as follows: When in use, hold the terminal cap body 1 by hand, then remove the outer insulation protection layer of two or more wires to expose the internal conductive parts, and then insert the conductive parts together onto the threaded connector 2 inside the terminal cap body 1. Then rotate the terminal cap body 1, and the wire conductive parts inside it will be screwed together, so that the conductive parts of different wires can be connected together. Then use the shielding component, one part of the shielding component is connected to the opening 3, and the other part is in a free moving state. Let the active end of the shielding component exert its unique function on the wire. At this time, the gap between the wire and the opening 3 can be shielded, so as to reduce impurities from entering the inside of the terminal cap body 1 through the gap between the wire and the opening 3.

[0037] As used in the specification and claims, certain terms are used to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in names as a way to distinguish components, but use the difference in functions of components as the criterion for distinction. As mentioned throughout the specification and claims, "comprising" is an open-ended term and should be interpreted as "including but not limited to". "Substantially" means within an acceptable error range. Those skilled in the art can solve technical problems within a certain error range and basically achieve the technical effect.

[0038] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a commodity or system including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such a commodity or system. Without further limitation, an element defined by the statement "including one..." does not exclude the existence of another identical element in the commodity or system including the element.

[0039] The above description shows and describes several preferred embodiments of the present utility model. However, as previously mentioned, it should be understood that the present utility model is not limited to the forms disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the inventive concept described herein through the above teachings or the techniques or knowledge in the relevant field.
