Description

Technical Field

[0001] The utility model relates to the technical field of T-shaped wire clamps, in particular to a T-shaped wire clamp which is easy to install. Background Art

[0002] T-type wire clamps are hardware that connects conductors and branch lines to transfer electrical loads and withstand certain mechanical loads. T-connected lines are two lines of the same voltage level that are connected at different spatial levels by short-circuiting lines. Substation A supplies power to substations B and C at the same time. The advantage is that it reduces investment and uses one less substation interval. This method of connecting another line from the main line is vividly called the "T" connection method, and this connection point is called the "T connection point".

[0003] After searching, the patent with the authorization publication number CN218958037U discloses an insulating T-type wire clamp, including an upper T-type wire clamp and a lower T-type wire clamp, the upper T-type wire clamp and the lower T-type wire clamp are connected by a buckle, a horizontal through hole and a vertical through hole are formed between the upper T-type wire clamp and the lower Y-type wire clamp, and the horizontal through hole and the vertical through hole are mutually connected, and the horizontal wire is passed through the inside of the horizontal through hole. At this time, the first bolt is screwed, and the rotation of the first bolt inside the first threaded hole drives the axial movement of the pressure plate, so that the left pressure head and the right pressure head limit the wire. At the same time, the arc pressure knife cuts the outer insulation skin of the middle part of the wire, and finally the arc pressure knife contacts the metal wire, passes the vertical wire through the inside of the vertical through hole, and its top end is against the arc pressure knife, and then the vertical wire is limited by the second bolt. The whole operation does not need to strip the insulation skin of the wire, and the limiting process of the wire can complete the connection of the metal wire inside the wire. It is convenient to operate and simple to use.

[0005] Most existing T-type wire clamps use screws to squeeze metal sheets downward to clamp the wires inside the wire clamp. However, in actual operation, multiple screws are required on the same wire clamp. During actual installation, they need to be tightened one by one, which is time-consuming and inconvenient.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] See also Figure 1-Figure 6A T-shaped wire clamp which is easy to install comprises a bottom clamp 1 and an upper cover 2, a mounting cavity 101 is provided at one end of the bottom clamp 1, a snap-on assembly is connected between the bottom clamp 1 and the upper cover 2, a plurality of limit openings 102 are provided on both sides of the mounting cavity 101, a moving cavity 103 is provided on the side away from each other of the two groups of limit openings 102, a moving assembly is connected to the inner walls of the two moving cavities 103, an elastic assembly is connected on the side away from each other of the two moving assemblies, wherein the moving assembly on the side away from the snap-on assembly is also connected to a pulling assembly, and one end of the pulling assembly away from the snap-on assembly passes through the elastic assembly and the bottom clamp 1, and is connected to the upper cover 2, the adjacent sides of the two groups of moving assemblies respectively pass through the two groups of limit openings 102, and a card plate 7 is arranged between the two groups of moving assemblies, card strips 15 are fixedly connected on both sides of the card plate 7, and the two card strips 15 respectively abut against the two groups of moving assemblies.

[0025] The utility model is a T-shaped wire clamp that is easy to install. It is similar to the existing T-shaped wire clamp structure, such as the insulating T-shaped wire clamp disclosed in the patent with publication number CN218958037U. The main improvement of the utility model is that when the user connects the wires through the bottom clamp 1 and the upper cover 2, the clamping strips 15 on both sides of the clamping plate 7 and the two movable components can be used to squeeze and fix the wires without the need for bolts, which is more convenient and quick. Figures 1 to 6 As shown, when the T-shaped wire clamp which is easy to install in the utility model is used, first, the wires to be connected are placed inside the installation cavity 101, and then the card plate 7 is inserted downward from the top of the installation cavity 101. While the card plate 7 is being inserted, the two card strips 15 on both sides of the card plate 7 squeeze the two moving components, and when the two moving components are squeezed, the elastic components on the other side will be squeezed. As the card plate 7 is continuously pressed downward, the wires inside the installation cavity 101 will be squeezed more and more, until the card plate 7 completely squeezes the wires. At the same time, the card plate 7 is restricted by the two moving components and cannot move upward, so that the wires can be kept in a fixed squeezed state; then the upper cover 2 is aligned with the bottom clip 1 and buckled down, and the upper cover 2 and the bottom clip 1 are restricted by the clamping component, and the pulling component is limited by the upper cover 2, so that it can not only prevent the upper cover 2 from being separated from the bottom clip 1, but also limit the pulling component to prevent the pulling component from unfolding by itself and affecting the limiting effect.

[0026] When the wires need to be loosened later, it is only necessary to pull the pulling component outward. After the pulling component is subjected to the pulling force, it will pull the moving component away from the side of the card connection component toward the inside of the moving cavity 103, and compress the elastic component while pulling. At this time, the card plate 7 lacks the limit on one side, so the card plate 7 can be taken out from the loosened side, and then the wires can be taken out of the installation cavity 101 of the bottom clip 1 again.

[0027] Please refer to Figure 3-Figure 5The moving component includes a connecting plate 12 and a plurality of limiting strips 13. The same side of the plurality of limiting strips 13 is fixedly connected to the connecting plate 12. The outer wall of the connecting plate 12 is slidably connected to the inner wall of the moving cavity 103. The side of the connecting plate 12 away from the limiting strip 13 is connected to the elastic component. The sides of the plurality of limiting strips 13 away from the connecting plate 12 respectively penetrate the plurality of limiting openings 102 and are slidably connected to the inner walls of the plurality of limiting openings 102. The sides of the plurality of limiting strips 13 penetrating the limiting openings 102 are against the card strip 15.

[0028] First of all, it should be noted that the cross-sections of the clamping strip 15 and the limiting strip 13 are both right-angled trapezoids, and the clamping strip 15 and the limiting strip 13 not only have their inclined surfaces but also their straight surfaces, wherein the inclined surface of the clamping strip 15 faces downward and the straight surface faces upward, and the inclined surface of the limiting strip 13 faces upward and the straight surface faces downward. To be more specific, when the clamping plate 7 is subjected to force and lowered, the inclined surfaces of the two clamping strips 15 on both sides of the clamping plate 7 will cause pressure on the inclined surfaces of several limiting strips 13 on the two connecting plates 12, and as the pressing force increases, the clamping strip 15 will push the limiting strip 13 toward the inside of the limiting opening 102, and then push the connecting plate 12 located in the movable cavity 103 together, and when the connecting plate 12 is forced and pushed, the connecting plate 12 will squeeze the elastic component on the other side.

[0029] Then the clamping strip 15 continues to descend, and when the clamping strip 15 passes through the first limit strip 13, the limit strip 13 returns to its original position under the action of the elastic component. At this time, according to the above steps, the downward pressure is maintained until the bottom surface of the clamping plate 7 completely rests against the outer wall of the wire, so that the clamping plate 7 stops without continuing to descend.

[0030] At this time, the straight surface above the clamping strip 15 is against the straight surface below the limiting strip 13, so the limiting strip 13 cannot be squeezed back into the limiting opening 102, and thus cannot be detached from the installation cavity 101. At this point, the wires can be squeezed and limited by the clamping plate 7 without the aid of bolts, which is convenient and easy to operate.

[0031] Please refer to Figure 4 and Figure 6 The elastic component includes a plurality of return springs 17, and a plurality of spring cavities 104 are provided on the side away from each other of the two movable cavities 103. The same end of the plurality of return springs 17 is fixedly connected to the side of the connecting plate 12 away from the limiting strip 13, and the other ends of the plurality of return springs 17 are fixedly connected to the inner walls of the plurality of spring cavities 104 respectively.

[0032] More specifically, when the connecting plate 12 is pushed by the limit bar 13, it will move inward along the movable cavity 103, thereby compressing the multiple return springs 17 located on the other side of the connecting plate 12. When the clamping strip 15 passes through the first limit bar 13, the multiple return springs 17 no longer have the squeezing force brought by the clamping strip 15, so they will instantly restore their deformation and push the connecting plate 12 outward again. Then, the clamping strip 15 can be blocked by the limit bar 13 to prevent it from falling off from the top of the installation cavity 101.

[0033] Please refer to Figure 2-Figure 4 and Figure 6 The pulling assembly includes a limit plate 9, a pull plate 10, a pull handle 11 and a plurality of pull rods 16. The same end of the plurality of pull rods 16 is fixedly connected to the side of the connecting plate 12 away from the limit strip 13. The other ends of the plurality of pull rods 16 pass through a plurality of reset springs 17 and the bottom clamp 1, and are fixedly connected to one side of the pull plate 10. The other side of the pull plate 10 is fixedly connected to the pull handle 11. The outer wall of the pull plate 10 abuts against the inner wall of the limit plate 9. The outer wall of the other end of the limit plate 9 is fixedly connected to the outer wall of the upper cover 2.

[0034] More specifically, when the card plate 7 needs to be taken out, it is only necessary to pull the pull plate 10 outward. The pull plate 10 and the plurality of pull rods 16 will be moved toward the outside of the movable cavity 103 and the spring cavity 104, so that one set of connecting plates 12 and the limit strips 13 can be forcibly retracted into the movable cavity 103. At this time, one side of the card plate 7 lacks a limit, so the card plate 7 can be taken out from this side.

[0035] What needs to be specially explained here is: under normal circumstances, when the upper cover 2 is covered on the bottom clamp 1, the upper cover 2 and the bottom clamp 1 bracket are not only limited by the clamping assembly, but the front end of the upper cover 2 is also clamped on the outer walls of the pull plate 10 and the handle 11 through the limiting plate 9, so that the pull plate 10 cannot be pulled without opening the upper cover 2, and therefore the clamping plate 7 cannot be separated from the previously squeezed wires. Through this operation, accidental touch or other reasons can be avoided, which causes the clamping plate 7 to reduce the limiting effect of the wires.

[0036] Please refer to Figure 1-Figure 4 The card-joining assembly includes two plugs 14, two upper blocks 4 and two bottom blocks 3. The two upper blocks 4 are fixedly connected to the outer walls of the upper cover 2 on both sides, and the two bottom blocks 3 are fixedly connected to the two sides of the outer wall of the bottom clamp 1 on both sides. The upper surfaces of the two bottom blocks 3 are penetrated with sockets 301. One ends of the two plugs 14 are fixedly connected to the bottom surfaces of the two upper blocks 4, and the other ends of the two plugs 14 penetrate the two sockets 301 and are slidably connected to the inner walls of the sockets 301.

[0037] More specifically, when the wires have been compressed by the clamping plate 7, it is only necessary to cover the upper cover 2 on the bottom clip 1, and during the covering process, insert the plug 14 on the upper block 4 into the socket 301 of the bottom block 3, thereby completing the connection between the upper cover 2 and the bottom clip 1; and it is worth mentioning here that: the sliding between the plug 14 and the socket 301 has a certain friction, and a certain amount of force is required to open it, in order to prevent the upper cover 2 and the bottom clip 1 from detaching by themselves.

[0038] Please refer to Figure 1-Figure 4 The upper surface of the card plate 7 is fixedly connected with a connecting rod 6, and the other end of the connecting rod 6 is fixedly connected with a pull button 5. The other end of the pull button 5 passes through the upper cover 2 and is slidably connected with the inner wall of the upper cover 2.

[0039] More specifically, by providing the connecting rod 6 and the pull button 5, it is more convenient to grip and apply force when pressing down and lifting the card plate 7.

[0040] Please refer to Figure 1-Figure 4 The two ends of the inner wall of the installation cavity 101 are fixedly connected with a top plate 8, and the adjacent sides of the two top plates 8 are respectively slidably connected with the side walls of the two groups of limit strips 13. By setting the top plate 8, a block can be set on both sides of the two groups of limit strips 13 to prevent the card plate 7 and the card strip 15 located inside the two groups of moving components from sliding off from both sides.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
