Description

Technical Field

[0001] This utility model relates to the field of photovoltaic connector technology, specifically to a button unlocking structure used on a connector. Background Technology

[0002] Traditional high-voltage energy storage connectors use multiple parts to fix the unlocking button or use glue to fix the unlocking button. Although the traditional structure achieves the unlocking function, its complexity increases product cost and assembly difficulty. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model provides a button unlocking structure for use on connectors to solve at least one of the above-mentioned technical problems.

[0004] The technical solution of this utility model is: a button unlocking structure for use on a connector, comprising a connector body, characterized in that a rubber-coated assembly is installed on the connector body, the surface of the rubber-coated assembly is provided with an opening, a button, a spring and a cover plate are sequentially installed on the opening from the inside to the outside, the cover plate is located outside the rubber-coated assembly, an extension end is provided below the cover plate, the surface of the extension end is provided with an annular rib, the outer contour of the rib fits the opening, and the rib is connected to the rubber-coated assembly by an interference fit;

[0005] The button has an internal channel, one end of the spring is located in the channel, and the other end of the spring abuts against the extension end. A notch is provided above the opening, and the notch is connected to the opening. A limiting member is provided on the upper surface edge of the button, and the installation direction of the limiting member is towards the cover plate. The limiting member passes through the notch. The upper surface of the extension end is provided with a sliding groove that is slidably connected to the limiting member.

[0006] This invention utilizes the ribs on the cover plate to insert into the rubber-coated assembly via an interference fit. Once installed in place, the ribs release and automatically fall into the opening of the rubber-coated assembly, achieving a secure fit and efficiently combining the button, spring, and rubber-coated assembly. Furthermore, the addition of notches and grooves in this invention better prevents button displacement, thus avoiding interference with the connector's operation.

[0007] More preferably, the opening extends through the rubber-coated assembly, and the length of the button is less than the length of the rubber-coated assembly.

[0008] This prevents buttons from being too long to fit entirely inside the connector.

[0009] Further preferably, the upper surface of the cover plate is provided with an upward protrusion, which abuts against the limiting member.

[0010] It can limit the position of the sliding of the limiting component.

[0011] Further preferably, the upper surface of the limiting member is inclined, and the thickness of the limiting member gradually decreases from near the cover plate to far away from the cover plate.

[0012] It allows for easy insertion into the interior of the coated component.

[0013] Further preferably, the outer contour of the button is stepped, and the interior of the channel is stepped, with the inner diameter of the channel near the cover plate being larger than the inner diameter of the channel away from the cover plate.

[0014] This limits the extension length of the spring and enhances its elasticity.

[0015] Further preferably, the interior of the extended end is hollow, and a fixing post is provided in the center of the extended end. The fixing post is connected to the center of the cover plate, and the spring is sleeved on the fixing post.

[0016] This can prevent the spring from shifting. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] Reference Figures 1-3As shown, a button unlocking structure for use on a connector includes a connector body 1. The connector body is characterized by an overmolded assembly 2, the surface of which has an opening 3. From the inside out, a button 4, a spring 5, and a cover plate 6 are sequentially installed on the opening. The cover plate is located outside the overmolded assembly, and an extension end 7 is located below the cover plate. The surface of the extension end has an annular rib 8, the outer contour of which fits the opening. The rib is connected to the overmolded assembly by an interference fit. The button has an internal channel, one end of the spring is located within the channel, and the other end of the spring abuts against the extension end. A notch is located above the opening, communicating with it. A limiting member 9 is located on the upper edge of the button, its installation direction facing the cover plate. The limiting member passes through the notch. A groove is provided on the upper surface of the extension end, which is slidably connected to the limiting member.

[0023] This invention utilizes the ribs on the cover plate to insert into the rubber-coated assembly via an interference fit. Once installed in place, the ribs release and automatically fall into the opening of the rubber-coated assembly, achieving a secure fit and efficiently combining the button, spring, and rubber-coated assembly. Furthermore, the addition of notches and grooves in this invention better prevents button displacement, thus avoiding interference with the connector's operation.

[0024] Further optimization involves an opening that extends through the overmolded assembly, and the length of the button is shorter than the length of the overmolded assembly. This prevents the button from being too long to fit entirely inside the connector.

[0025] Further preferably, the upper surface of the cover plate has an upward protrusion 10 that abuts against the limiting member. This can effectively limit the position of the limiting member during sliding.

[0026] Further preferably, the upper surface of the limiting member is inclined, and the thickness of the limiting member gradually decreases from near the cover plate to far away from the cover plate. This facilitates insertion into the interior of the overmolded assembly.

[0027] Further optimization involves a stepped outer contour of the button and a stepped interior channel, with the inner diameter of the channel near the cover plate being larger than that of the channel farther from the cover plate. This limits the spring's extension length and enhances its elasticity.

[0028] In a further preferred embodiment, the extension end is hollow inside, and a fixing post 11 is provided in the center of the extension end. The fixing post is connected to the center of the cover plate, and the spring is sleeved on the fixing post. This can prevent the spring from shifting.

[0029] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
