Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a self-stripping terminal block. Background Technology

[0002] In modern electrical and electronic equipment, terminal blocks are widely used as a key connecting element in various circuit connections. The main function of terminal blocks is to reliably connect wires or cables to electrical equipment, instruments, or other circuit components. With the increasing demand for miniaturization, integration, and automated production of electronic equipment, the market has placed higher requirements on the performance, reliability, and ease of installation of terminal blocks.

[0003] However, traditional terminal blocks still have certain drawbacks. For example, although some terminal blocks are equipped with wire stripping devices, the depth of cutting the wire sheath cannot be precisely controlled, which may damage the wire core during stripping and thus affect the stripping effect. Secondly, the stripping blades cannot be replaced, resulting in increasingly poor stripping performance over time. A search revealed that the technical solution provided by utility model application number CN202121783942.3 also suffers from the aforementioned problems. Utility Model Content

[0012] According to the self-stripping wire terminal block, the number of cutting blades is two and they are symmetrically distributed.

[0013] According to the self-stripping terminal block, the position of the scale corresponds to that of the mounting plate.

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-4 This utility model provides a self-stripping terminal block, comprising: a terminal block 1, a wire stripper 2 fixedly connected to the right end of the terminal block 1, a lead screw 3 threadedly connected to the inner surface of the wire stripper 2, a rotating block 4 fixedly connected to the outer surface of the lead screw 3, a limiting block 5 fixedly connected to the end of the lead screw 3 away from the rotating block 4, a mounting plate 6 rotatably connected to the outer surface of the lead screw 3, a scale 7 provided on the right surface of the wire stripper 2, a wire hole 8 provided on the outer surface of the wire stripper 2, a second bolt hole 14 provided on the outer surface of the mounting plate 6, the rotating block 4 being hexagonal in shape to facilitate the rotation of the lead screw 3, the outer surface of the limiting block 5 being rotatably connected to the mounting plate 6 to limit the movement of the lead screw 3, the outer surface of the wire stripper 2 being slidably connected to the mounting plate 6 to guide and limit the movement of the mounting plate 6, and the scale 7 being positioned corresponding to the mounting plate 6 to facilitate direct observation of the cutting depth of the cutting blade 11.

[0020] The outer surface of the mounting plate 6 is provided with a T-shaped groove 9, and the inner surface of the T-shaped groove 9 is slidably connected to a connecting plate 10. The lower surface of the connecting plate 10 is fixedly connected to a cutting blade 11. The outer surface of the connecting plate 10 is provided with a first threaded hole 12, and the inner surface of the first threaded hole 12 is threadedly connected to a bolt 13. The inner surface of the second bolt hole 14 is threadedly connected to the bolt 13, which facilitates the overall fixation of the cutting blade 11. The inner surface of the T-shaped groove 9 is slidably connected to the cutting blade 11, which facilitates the installation of the cutting blade 11. There are two cutting blades 11, which are symmetrically distributed.

[0021] Working principle: In use, rotating the rotating block 4 drives the lead screw 3 to move the mounting plate 6 outward under the limiting action of the limiting block 5, thereby moving the two cutting blades 11 away from each other. Then, insert the wire to be stripped into the wire hole 8 and place the stripping position between the two cutting blades 11. Then, rotate the rotating block 4 in the opposite direction, driving the mounting plate 6 to move the two cutting blades 11 towards each other until they contact the wire sheath and stop. Then, depending on the thickness of the wire sheath, rotate the rotating block 4 again until the mounting plate 6 points to the initial position of the scale 7 and matches the wire sheath thickness and stops rotating. At this point, the wire sheath is opened, and the precise control of the depth ensures that the wire core is not damaged. Then, rotate the wire and... Pulling the wire outwards allows you to strip the outer sheath, which is simple and convenient. Then, connect the exposed wire core to terminal 1 to complete the wiring operation. When the cutting blade 11 wears out after long-term use and needs to be replaced, simply loosen and remove the bolt 13 to release the restriction on the connecting plate 10 and the cutting blade 11 as a whole. Then, remove the connecting plate 10 and the cutting blade 11 as a whole along the T-slot 9 to complete the disassembly. Then, insert the new connecting plate 10 and the cutting blade 11 as a whole into the T-slot 9. When the first threaded hole 12 corresponds to the second bolt hole 14, screw in the bolt 13 to complete the installation of the connecting plate 10 and the cutting blade 11 as a whole. This simple and convenient process ensures that the device always maintains the best wire stripping effect.

[0022] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
