[0002] The distribution valve is a special control device for pipeline fluids. It is generally a solenoid valve composed of a solenoid coil and a valve column driven by magnetic force when the solenoid coil is energized. During the operation of the solenoid valve, the valve column is mainly driven to move up and down by energizing the coil assembly to achieve the closure of the internal opening of the convection pipe.

[0003] The coil assembly usually includes a hollow cylinder, enameled wire, a wiring plug, etc. The wiring plug is fixed on the hollow cylinder, and the enameled wire is wound around the hollow cylinder. After the two lead wires of the enameled wire extend out of the hollow cylinder, they need to extend a certain length before they can reach the wiring plug and be connected to the wiring plug.

[0004] The lead wire of the enameled wire is generally connected to the terminal plug by soldering on the terminal plug, but the soldering process requires more equipment and the installation is cumbersome, and the lead wire and the terminal plug are fixedly installed together and are not easy to disassemble. Utility Model Content

[0005] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the utility model is to provide a coil for a distribution valve, which facilitates the installation and removal of the enameled wire and the connector.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a coil for a distribution valve, comprising a hollow cylinder, an enameled wire wound on the surface of the hollow cylinder, circular platforms radially extending from the two axial sides of the hollow cylinder, two joint mechanisms being installed on one of the circular platforms, each of the joint mechanisms being respectively fixedly connected to the two ends of the enameled wire, the joint mechanism comprising a shell fixedly installed on the circular platform, an L-shaped connector slidably arranged in the shell, an L-shaped groove for the sliding of the L-shaped connector being provided in the shell, a through hole for the enameled wire to pass through being provided on one side of the L-shaped connector, and a clamping plate for clamping the enameled wire being installed on the L-shaped connector.

[0007] Furthermore, the L-shaped connector includes an external connector and a wiring connector, and the clamping plate is installed on the wiring connector.

When the clamp is located outside the L-shaped groove, the clamp is in a rotating state relative to the terminal head.

[0009] Furthermore, a spiral spring is installed between the clamping plate and the terminal head to drive the clamping plate away from the through hole.

[0010] Furthermore, there are two clamping plates, which are respectively located on both sides of the wiring head.

[0011] Furthermore, a plurality of convex strips are fixedly mounted on one side of the clamping plate close to the terminal head.

[0012] Furthermore, a groove corresponding to the convex strip is provided on the outer side of the terminal head.

[0013] Furthermore, a compression spring is fixedly installed in the L-shaped groove to drive the terminal head to retract into the L-shaped groove.

[0014] Furthermore, a guide rod is fixedly installed on the inner wall of the L-shaped groove, the external joint is slidably set on the guide rod, the compression spring is sleeved on the surface of the guide rod, one end of the compression spring is fixedly connected to the external joint, and the other end of the compression spring is fixedly connected to the inner wall of the L-shaped groove.

[0015] Compared with the prior art, the beneficial effect of the utility model is that in the process of connecting the lead-out wire of the enameled wire with the joint mechanism, the L-shaped connector is first manually pushed out of the L-shaped groove so that the end with the through hole extends out of the L-shaped groove, and then the lead-out wire of the enameled wire is passed through the through hole, and then the excess enameled wire is wrapped around the surface of the L-shaped connector, and then the L-shaped connector is retracted into the L-shaped groove. In this process, the enameled wire is clamped and fixed by the clamping plate and the L-shaped connector, so that the enameled wire is fixedly installed on the L-shaped connector. When disassembling, it is only necessary to push the L-shaped connector out of the L-shaped groove to release the clamping of the enameled wire by the clamping plate to complete the disassembly.

[0021] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1 and Figure 2 This embodiment provides a coil for a distribution valve, including a hollow cylinder 1, an enameled wire 2 is wound on the surface of the hollow cylinder 1, and circular platforms 3 are radially extended on both axial sides of the hollow cylinder 1. Two joint mechanisms 4 are installed on the upper circular platform 3, and each joint mechanism 4 is fixedly connected to both ends of the enameled wire 2. The enameled wire 2 is wound on the surface of the hollow cylinder 1, and the two lead wires of the enameled wire 2 are fixedly connected to the joint mechanism 4 respectively, and then connected to the outside through the joint mechanism 4 to connect the power supply.

[0023] See also Figure 1 , Figure 3 and Figure 4 The joint mechanism 4 includes a shell 41 fixedly mounted on the circular platform 3, an L-shaped connector 42 is slidably arranged in the shell 41, an L-shaped groove 43 for the L-shaped connector 42 to slide is provided in the shell 41, a through hole 44 for the enameled wire 2 to pass through is provided on one side of the L-shaped connector 42, and a clamping plate 45 for clamping the enameled wire 2 is installed on the L-shaped connector 42.

[0024] In the process of connecting the lead wire of the enameled wire 2 with the connector mechanism 4, the L-shaped connector 42 is first manually pushed out of the L-shaped groove 43 so that the end with the through hole 44 extends out of the L-shaped groove 43, and then the lead wire of the enameled wire 2 is passed through the through hole 44, and then the excess enameled wire 2 is wrapped around the surface of the L-shaped connector 42, and then the L-shaped connector 42 is retracted into the L-shaped groove 43. In this process, the enameled wire 2 is clamped and fixed by the clamping plate 45 and the L-shaped connector 42, so that the enameled wire 2 is fixedly installed on the L-shaped connector 42.

[0025] See also Figure 3 and Figure 4 , wherein the L-shaped connector 42 includes an external connector 421 and a terminal 422, and the clamp 45 is mounted on the terminal 422. The external connector 421 extends vertically from the L-shaped slot 43 for connecting to an external power source, and the terminal 422 can extend horizontally from the L-shaped slot 43 for convenient connection with the enameled wire 2.

[0026] See also Figure 3 and Figure 4, wherein the clamping plate 45 is hinged to the terminal head 422. When the clamping plate 45 is located in the L-shaped groove 43, the clamping plate 45 is in a stationary state relative to the terminal head 422, one side of the clamping plate 45 abuts against the inner wall of the L-shaped groove 43, and the other side of the clamping plate 45 abuts against the enameled wire 2. When the clamping plate 45 is located outside the L-shaped groove 43, the clamping plate 45 is in a rotating state relative to the terminal head 422.

[0027] When the terminal head 422 extends out of the L-shaped groove 43, the clamp 45 also extends out of the L-shaped groove 43, so that the clamp 45 rotates relative to the terminal head 422. At this time, the clamp 45 gradually moves away from the through hole 44, thereby exposing the through hole 44, which is convenient for the lead wire of the enameled wire 2 to pass through the through hole 44. Then the terminal head 422 drives the clamp 45 to shrink into the L-shaped groove 43. Under the action of the inner wall of the L-shaped groove 43, the clamp 45 is pushed close to the through hole 44. When the clamp 45 is completely retracted into the L-shaped groove 43, the clamp 45 completely clamps the enameled wire 2 located at the clamp 45 and the terminal head 422, thereby completing the fixation of the enameled wire 2 and the connector mechanism 4.

[0028] See also Figure 4 In order to facilitate the clamping plate 45 to automatically move away from the through hole 44 when it moves out of the L-shaped slot 43, and reduce the number of manual operation steps, a spiral spring 46 is installed between the clamping plate 45 and the terminal head 422 to drive the clamping plate 45 away from the through hole 44. Through the spiral spring 46, when the clamping plate 45 is fully extended out of the L-shaped slot 43, the clamping plate 45 is driven away from the through hole 44, so that the through hole 44 is exposed.

[0029] See also Figure 3 In order to improve the clamping force of the enameled wire 2 and strengthen the connection between the enameled wire 2 and the L-shaped connector 42, there are two clamping plates 45, which are respectively located on both sides of the connector 422. Thus, the two clamping plates 45 clamp the enameled wire 2 on both sides of the through hole 44 respectively.

[0030] See also Figure 3 and Figure 4 In order to further improve the tight connection between the enameled wire 2 and the L-shaped connection, a plurality of convex strips 47 are fixedly installed on one side of the clamping plate 45 close to the terminal head 422. A groove 48 corresponding to the convex strips 47 is provided on the outer side of the terminal head 422. The convex strips 47 and the grooves 48 increase the contact area between the enameled wire 2 and the clamping plate 45, and the enameled wire 2 and the terminal head 422, and increase the friction between the enameled wire 2 and the clamping plate 45, and the enameled wire 2 and the terminal head 422.

[0031] See also Figure 3 In order to facilitate the retraction of the terminal head 422 into the L-shaped groove 43, the terminal head 422 is also prevented from easily extending out of the L-shaped groove 43. A compression spring 49 is fixedly installed in the L-shaped groove 43 to drive the terminal head 422 to retract into the L-shaped groove 43, thereby preventing the terminal head 422 from easily extending out of the L-shaped groove 43 and preventing the enameled wire 2 from detaching from the terminal head 422.

[0032] See also Figure 3 A guide rod 410 is fixedly mounted on the inner wall of the L-shaped groove 43, an outer joint 421 is slidably arranged on the guide rod 410, a compression spring 49 is sleeved on the surface of the guide rod 410, one end of the compression spring 49 is fixedly connected to the outer joint 421, and the other end of the compression spring 49 is fixedly connected to the inner wall of the L-shaped groove 43. The guide rod 410 improves the stability of the L-shaped connector 42 moving in the L-shaped groove 43.
