Description

Technical Field

[0001] The present application relates to the technical field of wiring terminals, and in particular to a novel wiring terminal. Background Art

[0002] Terminals are parts that connect batteries to external conductors. In electrical engineering, terminals mostly refer to wiring terminals, also called wiring terminals. They are divided into single-hole, double-hole, socket, hook, etc., and materials include silver-plated copper, zinc-plated copper, copper, aluminum, iron, etc. Their main function is to transmit electrical signals or conduct electricity.

[0003] When using the existing double-hole terminal blocks, it is necessary to insert the wires into the holes inside them and then fix the wires by pressing and holding with bolts. However, when in use, the holes on the terminals are designed to be smaller in order to facilitate the fixing of the wires, and the holes are mostly designed in the middle part of the terminals and blocked by the side walls of the terminals. The user cannot intuitively observe the position of the wires and the holes, and cannot intuitively observe the position of the wires. As a result, when pressing and holding with bolts, the pressing direction is easily deviated, so that the fixing effect of the wires is poor. The above reasons make the connection between the wires and the terminals more troublesome. For this reason, the present application provides a new type of terminal block to improve this problem.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] Embodiment 1

[0036] like Figure 1-Figure 6 As shown, a new type of terminal block proposed in the first embodiment of the present application includes:

[0037] A housing 1 having a mounting cavity 101 formed thereon, an expansion structure 3 provided on the housing 1, the expansion structure 3 being used to change the volume of the mounting cavity 101, and the housing 1 being used to mount other components on the terminal;

[0038] The mounting member 2 is detachably mounted in the mounting cavity 101 through the expansion structure 3. When in use, the mounting cavity 101 is expanded through the expansion structure 3 to expand its internal volume, and the mounting member 2 is installed. After the installation is completed, the mounting cavity 101 is restored through the cooperation of the expansion structure 3, so that the mounting member 2 is connected to the housing 1;

[0039] A fixing hole 201 is provided on the mounting member 2. The mounting member 2 includes a fixing portion and a connecting portion. The mounting member 2 is connected to the expansion structure 3 through the connecting portion so that the mounting member 2 and the mounting cavity 101 are detachably connected. The fixing portion is used to fix the wire inserted in the fixing hole 201. When in use, the mounting member 2 is first connected to the wire through the fixing portion so that the end of the wire is installed in the fixing hole 201. When the user is installing, the wire can be installed when the mounting member 2 is not connected to the housing 1. At this time, the fixing hole 201 is exposed to the outside, which is convenient for the user to check the position between the fixing hole 201 and the wire. It is more convenient to install the wire. The fixing hole 201 and the fixing portion connect the wire to the mounting member 2, and then the wire is connected to the housing 1 through the mounting member 2. The wire does not need to be pressed by bolts, which further simplifies the installation of the wire and increases the convenience of the device.

[0040] The release member 4 is slidably mounted on the mounting member 2. When the release member 4 contacts the fixing portion of the mounting member 2, the fixing portion releases the fixing of the wire. When the wire needs to be replaced, the fixing portion releases the fixing of the wire by the release member 4, which facilitates the replacement of the wire and increases the practicality of the device.

[0041] Compared with the prior art, the wire is connected to the fixing hole 201 on the housing 1 through the fixing part of the mounting member 2, and then the volume of the mounting cavity 101 is expanded through the expansion structure 3. After the mounting member 2 is installed in the mounting cavity 101, the volume of the mounting cavity 101 is restored through the expansion structure 3. When disassembly is required, the fixing of the wire by the fixing part is released through the release member 4, which is also convenient for disassembly of the wire. When in use, the wire is connected after the mounting member 2 is disassembled from the housing 1, and the mounting member 2 is connected to the housing 1 through the expansion structure 3, which is convenient for the user to connect the wire to the terminal.

[0042] Embodiment 2

[0043] like Figure 1-Figure 6 As shown, the second embodiment discloses the mounting member 2, the expansion structure 3 and the release member 4 on the basis of the first embodiment. In the second embodiment, the mounting member 2 includes:

[0044] The mounting shell 202 is used to connect with the extension structure 3. There are two mounting shells 202, which are respectively mounted at both ends of the housing 1 through the extension structure 3. The fixing hole 201 is opened at one end of the mounting shell 202 for being inserted into the housing 1. The mounting shell 202 is used to accommodate the wire. The two mounting shells 202 are respectively used to connect two wires. When the mounting shell 202 is connected to the housing 1 through the extension structure 3, the two fixing holes 201 are aligned, so that the two wires are connected, and the wiring is completed. The mounting shell 202 is made of copper or other conductors, which is convenient for better connection between the wires;

[0045] The elastic sheet 203 is installed in the mounting shell 202. The elastic sheet 203 is arc-shaped. The elastic sheet 203 is a fixed part. The elastic sheet 203 is used to resist the wire. When in use, the arc-shaped protrusion of the elastic sheet 203 is away from the inner wall of the mounting shell 202. When the wire is inserted into the mounting shell 202, the elastic plate 203 resists the outer surface of the wire, thereby completing the pressing of the wire. The length of the elastic sheet 203 is greater than two-thirds of the length of the mounting shell 202. When the wire is inserted into the mounting shell 202, the elastic sheet 203 can press the wire. The installation of the wire is more convenient and also increases the stability of the wire when in use.

[0046] In the second embodiment, the housing 1 includes two L-shaped plates 102 connected in a sliding manner, and the space between the two L-shaped plates 102 forms a mounting cavity 101. Figure 1 From the main perspective, the two L-shaped plates 102 slide in the horizontal direction, and the extended structure 3 includes:

[0047] The slide bar 301 is installed on one of the L-shaped plates 102, and a slide hole 302 for accommodating the slide bar 301 is opened on the other L-shaped plate 102. The inner wall of the slide hole 302 restricts the side wall of the slide bar 301, so that the two L-shaped plates 102 can only slide in a straight line in the horizontal direction, thereby increasing the stability of the L-shaped plates 102 when sliding;

[0048] The connecting plate 303 is installed on the L-shaped plate 102. The connecting plates 303 on the two L-shaped plates 102 are connected by connecting bolts 304. When connection is required, the connecting plates 303 on the two L-shaped plates 102 are slid to align, and then the two connecting plates 303 are connected by the connecting bolts 304, so as to limit the sliding between the L-shaped plates 102 and increase the stability of the L-shaped plates 102 when in use;

[0049] The limiting block 305 is installed on the L-shaped plate 102 with a sliding hole 302, and the mounting shell 202 is provided with a limiting groove 306 for accommodating the limiting block 305. The limiting groove 306 is a connecting portion, and the length of the limiting block 305 is less than the length of the sliding rod 301. When in use, the two L-shaped plates 102 are first moved away from each other so that the distance between the end of the limiting block 305 and the inner wall of the other L-shaped plate 102 is greater than or equal to the width of the mounting shell 202, and the two mounting shells 202 are inserted into the outer shell 1. At this time, the L-shaped plate 102 is slid so that the limiting block 305 is inserted into the limiting groove 306, and the sliding direction of the mounting shell 202 in the outer shell 1 is limited, and the mounting shell 202 is connected to the outer shell 1, thereby completing the connection between the wire and the outer shell 1. When in use, the wire is indirectly connected to the outer shell 1 through the mounting shell 202, which increases the convenience of installing the wire.

[0050] In the second embodiment, the release member 4 includes:

[0051] The release rod 401 slides through the mounting shell 202. One end of the release rod 401 located inside the mounting shell 202 is connected to the elastic sheet 203. An extension plate 402 is installed on the release rod 401. When the release rod 401 pulls the elastic sheet 203 toward the outside of the mounting shell 202, the arc-shaped protrusion is close to the inner wall of the mounting shell 202, so that the elastic sheet 203 and the wire are in contact with each other, which facilitates the removal of the wire.

[0052] The resistance block 403 is slidably mounted on the mounting shell 202. The resistance block 403 is provided with an inclined surface on one side facing the release rod 401. The resistance block 403 is used to resist the expansion board 402, so that the release rod 401 pulls the elastic sheet 203 to elastically deform. When in use, the resistance block 403 is slid to make it close to the expansion board 402, and the expansion board 402 pulls the release rod 401 to slide outside the mounting shell 202 through the guidance of the inclined surface, so that the elastic sheet 203 releases the pressure on the wire. It is more convenient for the user to apply force by pushing the resistance block 403 than pulling the release rod 401.

[0053] Among them, a receiving groove is opened on the L-shaped plate 102 on which the sliding rod 301 is installed, and the receiving groove is used to accommodate the interference block 403 and the expansion board 402. The receiving groove is composed of a wide groove 404 and a narrow groove 405 that are connected. The narrow groove 405 is used to accommodate the expansion board 402. The width of the narrow groove 405 is smaller than the width of the interference block 403. The receiving groove is convenient for accommodating the interference block 403 and the expansion board 402 when the installation shell 202 is inserted into the outer shell 1. When the installation shell 202 is inserted into the outer shell 1, the interference block 403 is located in the wide groove 404 and is blocked by the side wall of the narrow groove 405, so that it will not contact the expansion board 402 when it is located inside the outer shell 1, so that the interference block 403 will not affect the deformation of the elastic sheet 203, thereby increasing the stability of the elastic sheet 203 when in use.

[0054] Embodiment 3

[0055] like Figure 1-Figure 6 As shown, the third embodiment further discloses the present application on the basis of the second embodiment. In the third embodiment, a vertical plate 5 is installed on the mounting shell 202, and a guide rod 6 sliding through the vertical plate 5 is installed on the abutment block 403. A connecting spring 7 is installed between the vertical plate 5 and the abutment block 403. The connecting spring 7 forces the abutment block 403 to move away from the expansion plate 402. Under normal conditions or when the mounting shell 202 is stationary, the abutment block 403 will not affect the elastic sheet 203, thereby increasing the practicality of the device. The connecting spring 7 is sleeved on the guide rod 6, and the inner cavity of the connecting spring 7 is limited by the outer wall of the guide rod 6, thereby limiting the deformation direction of the connecting spring 7, thereby increasing the stability of the connecting spring 7 during deformation.

[0056] In the third embodiment, a plug plate 8 is slidably mounted on the mounting shell 202, and one end of the plug plate 8 close to the inner wall of the mounting shell 202 is a pointed end, and the plug plate 8 is used to contact the wire. The side of the plug plate 8 close to the fixing hole 201 is an inclined surface. When the mounting shell 202 is inserted into the outer shell 1, the plug plate 8 is contacted by the inner wall of the outer shell 1, so that the pointed end of the plug plate 8 contacts the outer surface of the wire, further increasing the fixing effect of the wire.

[0057] In embodiment three, an arc block 9 is installed in the narrow groove 405, and an arc groove 10 for accommodating the arc block 9 is opened on the top of the expansion plate 402. When the mounting shell 202 is inserted into the outer shell 1, the arc block 9 is inserted into the arc groove 10 through the guidance of the arc surface, and contacts the expansion plate 402, so that the elastic sheet 203 is deformed and recessed into the interior of the mounting shell 202, so that it further contacts the wire, further increasing the device's fixing effect on the wire.

[0058] In the third embodiment, a protruding rod 11 is installed on one of the mounting shells 202, and a through hole 12 for accommodating the protruding rod 11 is opened on the other mounting shell 202. When the two mounting shells 202 are inserted into the outer shell 1, the protruding rod 11 is inserted into the through hole 12 to connect the two mounting shells 202, and then the fixing holes 201 on the two mounting shells 202 are aligned, thereby increasing the convenience of aligning the fixing holes 201.

[0059] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
