Technical Field

[0001] The utility model relates to a capacitor terminal box. Background Art

[0002] Capacitor-run motors and fans are widely used in various industries. In use, the terminal box, as a structural component, is indispensable. The terminal box is a bridge connecting the motor or fan to the external circuit and plays an important role. Currently, capacitors on existing terminal boxes are fixed either by screws or by cable ties, and in some cases, capacitors are not fixed at all but directly placed in the terminal box. When using screws to fix capacitors, capacitors with screw mounting holes and appropriate screws need to be purchased, resulting in a large variety of materials and high costs. When using cable ties to fix capacitors, appropriate cable ties need to be purchased, and it is difficult to pass the cable ties through the binding holes during assembly, making it inconvenient to bind the capacitors. Therefore, it is necessary to improve the design of the terminal box to facilitate the installation and fixation of capacitors. Summary of the Utility Model

[0019] The following combines the embodiments and the attached Figures 1 to 4 to further describe the present utility model.

[0020] A capacitor self-latching type junction box, as Figures 1-2As shown, it includes an upper cover 1 and a lower cover 4. The upper cover 1 and the lower cover 4 are detachably and hermetically fixedly connected. In this embodiment, a sealing ring 2 is provided between the upper cover 1 and the lower cover 4, and the two are fixed by screws 7. The lower cover is used to install a capacitor 3 and a wiring terminal 5. A groove 8 and a wire inlet hole 9 are also provided on the lower cover. The wire inlet hole is located at one end of the groove, and the other end of the groove extends to the side wall of the lower cover. An outlet nozzle 6 is also provided on the junction box. The outlet nozzle is located on the lower cover and is fixedly connected to the lower cover.

[0021] Inside the lower cover 4, there are a self-latching tongue 13 and a fixing post 10. Both the self-latching tongue 13 and the fixing post 10 are fixedly connected to the lower cover 4. In this embodiment, the self-latching tongue 13, the fixing post 10, and the lower cover 4 are integrally injection-molded. The self-latching tongue 13 is tongue-shaped. The self-latching tongue 13 is arranged on the center line of the groove 8, that is, the groove 8 passes through the self-latching tongue 13 from one side of the lower cover 4 to the other side. At the same time, the fixing posts 10 are symmetrically distributed on both sides of the groove 8. The self-latching tongue 13 and the fixing posts 10 are on the same side of the capacitor 3. In this way, the wires are arranged through the groove 8, making the internal wiring of the junction box neater. One end of the self-latching tongue 13 is fixedly connected to the bottom of the lower cover 4, and the other end of the self-latching tongue 13 is a free end. The height of the self-latching tongue 13 is greater than the radius of the capacitor 3. In this way, when the capacitor 3 is placed in the self-latching tongue 13, the self-latching tongue 13 can firmly hold the capacitor 3. During production and processing, a certain pre-tightening force is applied to the self-latching tongue 13. The way to obtain the pre-tightening force is to tilt the self-latching tongue 13 in the vertical direction. In addition, in order to improve the strength of the self-latching tongue 13, a reinforcing rib is provided on the side of the self-latching tongue 13, and the reinforcing rib is fixedly connected to the self-latching tongue 13.

[0022] As Figures 3-4 shown, the distance between the self-latching tongue 13 and the side wall of the lower cover 4 is consistent with the diameter of the capacitor 3. When installing the capacitor 3, the capacitor 3 is pressed against the bottom and side wall of the lower cover 4 under the action of the pre-tightening force of the self-latching tongue 13. The self-latching tongue 13 can effectively fix the capacitor 3 by its own pre-tightening force. In this embodiment, the material of the self-latching tongue 13 is plastic, and a certain pre-tightening force can be applied to the self-latching tongue 13 during injection molding. In other embodiments, the material of the self-latching tongue 13 can also be other materials that can undergo a certain deformation under external force.

[0023] The fixing post 10 is used to install and fix the wiring terminal. The fixing post 10 is composed of a first connecting portion 11 and a second connecting portion 12. The first connecting portion 11 and the second connecting portion 12 are fixedly connected. The first connecting portion 11 is attached to the bottom of the lower cover 4, and the second connecting portion 12 protrudes vertically upward from the first connecting portion 11. The second connecting portion 12 is a protruding cylindrical structure for being inserted into the wiring terminal.

[0024] Through the improvement design of the structure inside the junction box, the utility model obtains a junction box capable of self-latching a capacitor, and makes the internal structure of the junction box more reasonable and compact, and the wiring is neat and clear.

[0025] The specific embodiments are only used to explain and illustrate the utility model, rather than limiting the utility model. Any change and replacement made to the utility model without creative labor within the scope of the concept and the claims of the utility model fall within the protection scope of the utility model patent.
