Description

Technical Field

[0001] This utility model relates to the field of power auxiliary technology, and in particular to a universal connection device. Background Technology

[0002] Connection devices are widely used in many fields to achieve reliable connections between objects. They play a crucial role, especially in electrical connection scenarios where current needs to be conducted. Connection mechanisms ensure that current can flow smoothly and stably at both ends of the connection, meeting the needs of normal operation of electrical equipment. In today's rapidly developing technological society, universal connection devices have a wide range of applications and are of great significance. Various devices require a large number of reliable connection devices to ensure power supply and signal transmission. Universal connection devices can quickly and stably connect wires and equipment, improving the assembly efficiency and operational stability of production lines.

[0003] A search revealed Chinese Patent Publication No. CN206180133U, which discloses a universal wire connection device. The purpose of this utility model is to provide an improved universal wire connection device. This utility model includes a U-shaped component and wire pressing blocks disposed on the U-shaped component. The inner side of the U-shaped component has a U-shaped wire pressing groove, and the U-shaped component has an I-shaped wire pressing slider that can move up and down within the wire pressing groove. Two corresponding U-shaped guide grooves are provided on the left and right sides of the wire pressing groove. Each of the four corners of the wire pressing slider has a limiting block that cooperates with the guide groove. Through the sliding wire pressing slider, the height of the wire pressing slider can be adjusted as needed to accommodate wires of different diameters. It features a compact structure, strong applicability, and durability. However, the above structure does not consider the problem that after long-term use, the wire may loosen, resulting in insecure fixing and easy detachment of the connected copper wire. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a universal connection device, which aims to improve the problem in the prior art that the copper wires are easily loosened after long-term use, resulting in insecure fixing and easy detachment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a universal connecting device, comprising a housing, wherein a plurality of clamping pieces are slidably connected to the inner wall of the housing, a plurality of anti-slip pieces are fixedly connected to the inner wall of the clamping pieces, a spring is fixedly connected between adjacent clamping pieces, a locking block is slidably connected to the outer wall of the clamping pieces, a sliding groove is provided on the inner wall of the locking block, a pressing block is slidably connected to the outer wall of the locking block, a screw is rotatably connected to the top surface of the pressing block, a cross cap is fixedly connected to the top surface of the screw, and an electrical connection mechanism is provided inside the housing for connecting the two ends.

[0006] Through the above technical solution: the outer shell is the protective and supporting structure of the entire device, made of high-strength insulating engineering plastic, with good mechanical and insulating properties. The clamping plates are evenly distributed inside the outer shell, and multiple anti-slip plates are fixedly connected to the inner wall of the clamping plates. The surface of the anti-slip plates is designed with fine texture, which can fully contact the surface of the object when the clamping plates clamp it, greatly increasing the friction and thus effectively preventing the clamped object from loosening. Under normal conditions, the spring is in a compressed state, providing a continuous outward pushing force to the clamping plates, so that the multiple clamping plates can open. The locking block is circular, with a groove inside that matches the outer wall of the clamping plates. The inner wall of the locking block is provided with a sliding groove. The surface of the sliding groove is smooth, providing guidance and limiting for the sliding of the locking block, ensuring smooth and stable movement of the locking block. The shape of the squeezing block is adapted to the locking block, and the bottom surface is in close contact with the outer wall of the locking block. A screw is rotatably connected to the top surface of the squeezing block.

[0007] As a further description of the above technical solution:

[0008] The electrical connection mechanism includes a conductive block, which is fixedly connected to the inner wall of the outer shell. A threaded groove is formed on the outer wall of the conductive block, and a screw is rotatably connected to the outer wall of the threaded groove. A contact block is rotatably connected to the bottom of the screw, and a cross cap is fixedly connected to the top of the screw.

[0009] Through the above technical solution: the conductive block is the core component of the electrical connection mechanism, responsible for the conduction of current. The inner wall of the conductive block is fixedly connected to the outer shell to ensure its stability and reliability. A threaded groove is opened on the outer wall of the conductive block, which allows for effective rotational connection with the external screw to achieve the function of fixation. The screw can be rotated to adjust the pressure and position of the contact block to ensure good electrical contact. The contact block is rotatably connected to the bottom of the screw, and the contact block can contact the wire to realize the transmission of current. The shape and material of the contact block must ensure good conductivity and wear resistance. A cross cap is fixedly connected to the top of the screw, which is used to rotate the screw to adjust the tightness of the contact block, making the operation more convenient.

[0010] As a further description of the above technical solution:

[0011] The top surface of the outer casing has a countersunk hole one, and the top of the outer casing has a countersunk hole two.

[0012] Through the above technical solution: the top surface of the outer shell is provided with countersunk hole one and countersunk hole two, which can accommodate corresponding fasteners to ensure the stability of the structure.

[0013] As a further description of the above technical solution:

[0014] The lower end of the inner wall of the countersunk hole one is provided with thread two, and the lower end of the inner wall of the countersunk hole two is provided with thread one.

[0015] The above technical solution ensures a tight and stable threaded connection between thread 2 and thread 1, effectively preventing loosening due to vibration and prolonged use.

[0016] As a further description of the above technical solution:

[0017] The outer wall of the housing is fixedly connected to a mounting block, and the outer wall of the mounting block is provided with mounting holes.

[0018] The above technical solution involves a mounting block fixedly connected to the outer wall of the housing. The mounting block provides convenience and options for the installation of the entire universal connection device. Mounting holes are provided on the outer wall of the mounting block, which helps to connect with other connecting parts during the installation process, making the installation process smoother.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the clip is inclined, and the outer wall of the locking block is inclined.

[0021] Through the above technical solution: the inclined surface of the clamping piece has an inclination angle, which allows the clamping piece to decompose and transmit the force it receives when interacting with the locking block, based on the characteristics of the inclined surface, thereby completing the clamping action. The inclined surface of the locking block can fit tightly with the inclined surface of the clamping piece and remain stable during relative sliding.

[0022] As a further description of the above technical solution:

[0023] The outer wall of the extrusion block is inclined, and the anti-slip sheet is fixed at an angle.

[0024] Through the above technical solution: the outer wall of the extrusion block is inclined, which together with the inclined surfaces of the locking block and the clamping plate forms a mechanical structure. When an external force is applied to the inclined surface of the extrusion block, the force can be evenly distributed to the locking block and the clamping plate below. Through the interaction between the inclined surfaces, the clamping plate can be precisely controlled, thereby adjusting the clamping force on the connected object. The anti-slip plate is fixed at an angle, so that when the clamping plate clamps the connected object, the anti-slip plate can be better embedded into the surface of the connected object, and the anti-slip effect is enhanced by the inclined friction.

[0025] As a further description of the above technical solution:

[0026] The inner wall of thread two engages with screw two, and the outer wall of thread one engages with screw one.

[0027] The above technical solution effectively prevents the connection from loosening due to external forces by the engagement of the thread and the screw, ensuring the reliable operation of the entire universal connection device in various complex environments.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, by passing the wire clamps through each other, the pressing block presses downwards. The inclined design of the pressing block and the locking block allows the screw to push the locking block to the left. The outer wall of the spring is inclined. When the locking block moves, multiple clamps press towards the center, so that the inner wall of the clamps tightly clamps the wire.

[0030] 2. In this utility model, the conductive wire is placed below the contact block, the cross cap is rotated, and the screw moves downward, so that the contact block presses against the outer wall of the conductive wire. The current is transmitted to the other side through the contact block, the screw, and the conductive block, thus realizing the connection of the current. Attached Figure Description

A contact block 202 is rotatably connected to the bottom of the screw 203. A cross cap 204 is fixedly connected to the top of the screw 203.

[0042] Specifically, the conductive block 201 is the core component of the electrical connection mechanism 2, responsible for conducting current. The inner wall of the conductive block 201 is fixedly connected to the outer shell 1 to ensure its stability and reliability. A threaded groove 205 is provided on the outer wall of the conductive block 201, which allows for effective rotational connection with the screw 203 to achieve the fixing function.

The contact block 202 is rotatably connected to the bottom of the screw 203, and the contact block 202 can contact the wire to realize the transmission of current. The shape and material of the contact block 202 must ensure good conductivity and wear resistance. A cross cap 204 is fixedly connected to the top of the screw 203 for rotating the screw 203 to adjust the tightness of the contact block 202, making operation more convenient.

[0043] Please see the appendix Figure 1 - Appendix Figure 3 The top surface of the outer shell 1 is provided with a countersunk hole 13, the top of the outer shell 1 is provided with a countersunk hole 14, the lower end of the inner wall of the countersunk hole 13 is provided with a thread 16, the lower end of the inner wall of the countersunk hole 14 is provided with a thread 15, and the outer wall of the outer shell 1 is fixedly connected with a mounting block 11, and the outer wall of the mounting block 11 is provided with a mounting hole 12.

[0044] Specifically, the top surface of the outer casing 1 is provided with countersunk hole 13 and countersunk hole 14. The lower end of the inner wall of countersunk hole 13 is provided with thread 16. Thread 16 ensures that it can achieve a tight and stable threaded connection with the corresponding connecting parts, preventing loosening due to vibration or long-term use.

The inclined surface of the locking block 5 can fit tightly with the inclined surface of the clamping piece 3 and remain stable during relative sliding. The outer wall of the pressing block 6 is also inclined, forming a mechanical structure together with the inclined surfaces of the locking block 5 and the clamping piece 3. When an external force is applied to the inclined surface of the pressing block 6, the force can be evenly distributed to the locking block 5 and the clamping piece 3 below. Through the interaction between the inclined surfaces, the clamping piece 3 can be precisely controlled, thereby adjusting the clamping force on the connected object.

[0047] Working principle: When it is necessary to fix the wire, strip the wire end to expose the conductive wire, pass it through the clips 3, and turn the cross cap 9. The cross cap 9 will press the pressing block 6 downward. Due to the inclined design of the pressing block 6 and the locking block 5, the screw 7 can push the locking block 5 to the left. The outer wall of the spring 4 is inclined. When the locking block 5 moves, the multiple clips 3 are pressed towards the middle, so that the inner wall of the clips 3 tightly clamps the wire.

[0048] Place the conductive wire under the contact block 202, rotate the cross cap 204, and the screw 203 moves downward, so that the contact block 202 presses against the outer wall of the conductive wire. The current is transmitted to the other side through the contact block 202, the screw 203 and the conductive block 201, realizing the connection of the current.
