Description

Technical Field

[0001] This invention relates to a connector device for electrical equipment, and more specifically to a flexible connector for rotary adaptive power equipment. Background Technology

[0002] Because various electrical equipment and measuring instruments differ, the diameter of their electrical sockets also varies. If the socket diameter is larger than the diameter of the flexible connector's post, poor contact can easily occur, leading to incorrect measurement results. Furthermore, excessive plugging and unplugging of electrical equipment can cause frictional wear and deformation of the metal, resulting in a smaller post diameter and thus poor contact. On the other hand, sometimes electrical equipment sockets need to directly connect the post to the wire. In this case, alligator clips are usually attached to the socket to clamp the wire, which is inconvenient. If alligator clips are not available, the wire must be wrapped around the post, which presents an unreliable connection problem. Summary of the Invention

[0003] The purpose of this invention is to provide a rotary adaptive flexible connector for electrical equipment that can adapt to the connection needs of sockets of electrical equipment with different apertures.

[0004] The technical solution of this invention is:

[0005] A flexible connector for a rotating adaptive power equipment, comprising:

[0006] The front end of the accelerator is closed, and the front end of the accelerator is provided with several radial grooves.

[0007] The conductor poles correspond one-to-one with the radial grooves, and the conductor poles slide along the corresponding radial grooves.

[0008] A rotating impeller is rotatably mounted inside the clutch cylinder via an impeller shaft. The impeller has several evenly distributed arc grooves circumferentially around the impeller shaft, each corresponding to a conductor pole. Radial grooves extend radially along the impeller shaft, and are evenly distributed circumferentially around the impeller shaft. One end of each conductor pole passes through a corresponding arc groove.

[0009] A spiral spring is used to drive a rotating impeller to rotate around its shaft, causing each conductor post to move away from the impeller shaft along its corresponding radial groove. Thus, when engaging with a socket in an electrical device, the rotating impeller is first driven to rotate, causing each conductor post to move towards the impeller shaft along its corresponding radial groove; then, each conductor post is inserted into the socket; next, the rotating impeller is released, and then the spiral spring drives it to rotate around its shaft again, causing each conductor post to move away from the impeller shaft along its corresponding radial groove (expanding the conductor posts). This allows each conductor post to press firmly against the inner wall of the socket under the action of the spiral spring, thus connecting the circuit. It can accommodate sockets of different diameters.

[0010] Preferably, the side wall of the clutch cylinder is provided with a finger groove extending circumferentially along the impeller shaft, and the rotating impeller is provided with a finger extending radially along the impeller shaft, the end of which passes through the finger groove and is located outside the clutch cylinder. In this way, the rotating impeller can be driven to rotate by the finger, which is convenient for actual operation.

[0011] Preferably, the inner wall of the finger slot is provided with several finger limiting slots equidistantly distributed along the circumference of the impeller shaft. The rotating impeller can move axially along the impeller shaft to allow the finger to move into the finger limiting slot. Thus, when engaging with a conductor, the conductor is first placed between the conductor posts; then, the rotating impeller is driven to rotate (overcoming the force of the spiral spring), causing the corresponding radial sliding posts to move towards the impeller shaft until the conductor posts clamp the conductor; next, the finger is moved into the corresponding finger limiting slot, thereby fixing the rotating impeller and keeping the conductor posts clamping the conductor, thus connecting the circuit. In this way, the rotary adaptive flexible connector for power equipment in this solution also functions as an alligator clip.

[0012] Preferably, the conductor pole has several grooves located on the outside of the accelerator cylinder. This increases the contact friction between the conductor pole and the conductor when the flexible connector for the rotating adaptive power equipment is used with the conductor, ensuring reliable contact and completing the connection.

[0013] Preferably, the conductor electrode includes an electrode body, an electrode screw hole at one end of the electrode body, and an electrode bolt that mates with the electrode screw hole. The electrode body is located outside the clutch cylinder, and the electrode bolt passes sequentially through a corresponding arc groove and a radial sliding groove. This facilitates the installation and removal of the conductor electrode.

[0014] Preferably, the front end of the clutch cylinder has a mounting screw hole at the center, and a pulsator bolt is installed in the mounting screw hole, which constitutes the pulsator shaft. This facilitates the installation and removal of the rotating pulsator.

[0015] Preferably, the convergence cylinder, the rotating impeller, and the impeller shaft are coaxially distributed.

[0016] Preferably, one end of the arc groove is close to the center of the rotating impeller, and the other end of the arc groove is close to the edge of the rotating impeller.

[0017] Preferably, the conductor pole has a fan-shaped cross-section, with the arc edge of the cross-section facing away from the axis of the accelerator cylinder. This ensures that when mated with a socket in an electrical device, the conductor pole will engage with the inner wall of the socket via the arc surface, facilitating reliable contact between the conductor pole and the socket and completing the connection.

[0018] Preferably, the device also includes a base, a rear end opening of the clutch cylinder with the rear end of the clutch cylinder facing the base, the clutch cylinder being fixed to the base by fixing bolts, and the base having a cable through hole that is connected to the inner cavity of the clutch cylinder.

[0019] The beneficial effects of this invention are:

[0020] Firstly, when engaging with the sockets of electrical equipment, the rotating impeller is first driven to rotate, causing each conductor post to move towards the impeller shaft along its corresponding radial groove. Next, each conductor post is inserted into the socket of the electrical equipment. Then, the rotating impeller is released, and the rotating impeller is driven to rotate around the impeller shaft by a spiral spring, causing each conductor post to move away from the impeller shaft along its corresponding radial groove (expanding each conductor post). This allows each conductor post to be pressed tightly against the inner wall of the socket under the action of the spiral spring, thus connecting the circuit. It can adapt to the connection needs of sockets with different diameters.

[0021] Secondly, the rotary adaptive flexible connector for power equipment of the present invention also functions as an alligator clip, and can be used with the conductor to connect the line. Attached Figure Description

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0036] Specific Implementation Example 1: As shown in the example Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a flexible connector for rotary adaptive power equipment includes a cusp cylinder 1, conductor posts 2, a rotating impeller 3, and a spiral spring 4. The front end of the cusp cylinder is closed, and the front end of the cusp cylinder has several radial grooves 1.1. The rotating impeller 3 is rotatably mounted inside the cusp cylinder via an impeller shaft, and the rotating impeller has several circular arc grooves 3.1 evenly distributed around the impeller shaft. The two ends of the circular arc grooves penetrate the two end faces of the rotating impeller. One end of the circular arc groove is close to the center of the rotating impeller, and the other end of the circular arc groove is close to the edge of the rotating impeller. The radial grooves extend radially along the impeller shaft, and each radial groove is evenly distributed around the impeller shaft. The conductor posts correspond one-to-one with the radial grooves, and the conductor posts slide along the corresponding radial grooves. The circular arc grooves correspond one-to-one with the conductor posts, and one end of the conductor post passes through the corresponding circular arc groove. In this embodiment, the conductor posts are parallel to the impeller shaft, and there are three conductor posts. The spiral spring is located inside the clutch cylinder. One end of the spiral spring is connected to the rotating impeller, and the other end of the rotating impeller is connected to the inner wall of the clutch cylinder. The spiral spring drives the rotating impeller to rotate around the impeller axis, causing each conductor pole to move away from the impeller axis along its corresponding radial groove. During the rotation of the rotating impeller, each conductor pole will move along its corresponding radial groove under the action of the arc groove.

[0037] The specific use of a rotary adaptive flexible connector for power equipment in this embodiment is as follows: The three core wires 8.1 inside the flexible cable 8 are connected one-to-one to the conductor posts (for example, by welding). When engaging with the socket of the electrical equipment, first drive the rotating impeller to rotate, causing each conductor post to move towards the impeller shaft along its corresponding radial groove. Then, insert each conductor post into the socket of the electrical equipment. Next, release the rotating impeller, and then drive the rotating impeller around its shaft via a spiral spring, causing each conductor post to move away from the impeller shaft along its corresponding radial groove (expanding the conductor posts). This allows each conductor post to press tightly against the inner wall of the socket under the action of the spiral spring, thus connecting the circuit. It can adapt to the connection needs of sockets with different diameters. When removing the rotary adaptive flexible connector for power equipment, first drive the rotating impeller to rotate, causing each conductor post to move towards the impeller shaft along its corresponding radial groove, and then pull it out.

[0038] Specifically, such as Figure 1 , Figure 3 As shown, a flexible connector for a rotating adaptive power device also includes a base 5. The rear end of the cusp holder is open, and the rear end of the cusp holder faces the base. The cusp holder is fixed to the base by fixing bolts 7. The base has a cable through-hole 5.1, which communicates with the inner cavity of the cusp holder. In use, the flexible cable is passed through the cable through-hole, and then the three core wires inside the flexible cable are connected one-to-one to the conductor terminals (for example, by welding). Then, the cusp holder is fixed to the base by the fixing bolts.

[0039] Furthermore, the convergence cylinder, the rotating impeller, and the impeller shaft are coaxially distributed.

[0040] like Figure 1 As shown, a mounting screw hole is provided at the center of the front end of the clutch cylinder, and a pulsator bolt 6 is installed on the mounting screw hole. This pulsator bolt constitutes the pulsator shaft. This facilitates the installation and removal of the rotating pulsator.

[0041] Furthermore, the conductor pole has a fan-shaped cross-section, with the arc edge of the cross-section facing away from the axis of the accelerator cylinder. Thus, when mated with the socket of electrical equipment, the conductor pole will engage with the inner wall of the socket through its arc surface, facilitating reliable contact between the conductor pole and the socket and completing the connection.

[0042] Furthermore, such as Figure 1 , Figure 3As shown, the conductor pole 2 includes a pole body 2.1, a pole screw hole at one end of the pole body, and a pole bolt 2.2 that mates with the pole screw hole. The pole body cannot pass through the radial groove. The pole body is located outside the accelerator cylinder, and the pole bolt passes through the corresponding arc groove and radial groove in sequence. This facilitates the installation and removal of the conductor pole. Furthermore, when connecting the three core wires in the flexible cable to the conductor pole one-to-one, the three core wires in the flexible cable are also connected to the pole bolt one-to-one (e.g., by welding).

[0043] Furthermore, such as Figure 1 , Figure 2 As shown, the side wall of the clutch cylinder is provided with a finger groove 1.2 extending circumferentially along the impeller shaft, and the rotating impeller is provided with a finger 3.2 extending radially along the impeller shaft. The end of the finger passes through the finger groove and is located outside the clutch cylinder. In this way, the rotating impeller can be driven to rotate by the finger, which is convenient for actual operation.

[0044] Furthermore, such as Figure 1 , Figure 2 As shown, the inner wall of the finger slot is provided with several finger limiting slots 1.3 distributed equidistantly along the circumference of the impeller shaft. The rotating impeller can move axially along the impeller shaft, so that the finger moves from the finger slot into the finger limiting slot or vice versa. In this way, when engaging with the conductor, the conductor can be placed between the conductor poles first; then, the rotating impeller is driven to rotate (overcoming the force of the spiral spring), causing the corresponding radial sliding post to move towards the impeller shaft until the conductor poles clamp the conductor; then, the finger is moved into the corresponding finger limiting slot, thereby fixing the rotating impeller and keeping the conductor poles clamping the conductor, so that the line is connected. In this way, the rotary adaptive power equipment flexible connector of this solution also functions as an alligator clip.

[0045] Furthermore, the conductor pole is provided with several grooves, each groove distributed along the axial direction of the conductor pole. The grooves are located on the outer side of the accelerator sleeve. In this way, when the flexible connector for the rotating adaptive power equipment is used with the conductor, the contact friction between the conductor pole and the conductor can be increased, ensuring reliable contact and completing the connection.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
