Description

Technical Field

[0001] This utility model belongs to the field of switch technology, specifically relating to a switch latch assembly and its discharge socket. Background Technology

[0002] In existing electrical connectors, such as common wall sockets, power strips, or other special male-female connectors, a switch structure is usually set up to control the conduction of the internal circuit at the power supply end in order to achieve the function of safe use of electricity. Specifically, before the male plug of an external electrical appliance or other device is inserted into the female electrical connector, the switch structure ensures that the female electrical connector is not energized. After the plug is inserted, the switch structure controls the connection of electricity, which can provide a certain degree of safety guarantee.

[0003] Many existing electrical connector switches are simply used to control the internal power supply of the female connector. In conventional equipment, the plug can be directly unplugged when the switch is closed and the power is on. However, if the current or voltage is high, this can cause electric arcing and other safety hazards when unplugging while the power is on. To reduce this hazard, existing technologies integrate a mechanical locking mechanism into the switch structure. When the plug is inserted, the switch closes and locks the plug to the connector, creating a fixed connection that prevents the plug from being easily unplugged, thus providing a safety guarantee.

[0004] However, the existing locking structure needs to be used in conjunction with a switch, and the structure design is usually quite complex with many transmission mechanisms. In particular, the locking method requires clamping and locking from two opposite sides of the plug, which requires at least two movable ends for clamping and fixing. This results in the transmission mechanism having at least two opposite movable ends, which not only increases the cost but also poses challenges to assembly and service life. Utility Model Content

[0036] Example 1:

[0037] This embodiment discloses a switch latch assembly, which is used to install on an electrical connector to control the on / off state of the internal circuit of the electrical connector and to form a locking and limiting effect when connecting an external plug.

[0038] It should be noted that the switch locking assembly in this embodiment can be applied to various types of electrical connectors. In a broad sense, an electrical connector is a connector with a male and female connection method, which conducts electricity through conductors with metal contact inside. Generally, the female electrical connector is the power supply side, providing power to the male plug. This embodiment describes the setting using an electrical connector with a female connector, which can be applied to conventional plug structures or the plug structure with locking groove as defined in this embodiment.

[0039] Specifically, in this embodiment, the switch latch assembly is disposed in an electrical connector. The electrical connector, as a female connector, has at least one socket for mating with an external plug. The electrical connector has a metal conductor connected to the metal pins of the plug. The switch latch assembly is a mechanical mechanism that can control the energization state between the metal conductor in the electrical connector and the external circuit.

[0040] The switch latch assembly includes a button and a sliding block structure, both of which are movable relative to the electrical connector. The button and the sliding block are linked, meaning that the sliding block moves in tandem with the button. This linkage means that when the button moves, the sliding block also moves, and the directions of movement are related; that is, if the button changes its direction of movement, the sliding block also changes its direction of movement.

[0041] The sliding plug has a protrusion that extends through the socket and contacts and abuts against the plug inserted into the socket to achieve a limiting effect. The socket has a recess; after the plug is inserted into the recess, its outer wall conforms to the inner wall of the recess, thus creating a limiting effect. That is, the plug can only be pulled out perpendicular to the end face of the recess without deformation, and the protrusion perpendicular to the pulling direction abuts against the plug, thereby achieving the limiting effect.

[0042] One implementation method is to adapt to existing common plug structures, meaning there are no special structural limitations on the plug. It has a smooth outer surface that can completely conform to the inner wall of the recessed groove of the socket. A second through hole is provided on the inner wall of the recessed groove for the internal sliding plug to pass through. At the end of the sliding plug, there is a friction-increasing material, such as a rubber deformation structure. By pressing the button, the protrusion of the sliding plug inside the connector protrudes through the second through hole. The deformation structure deforms against the surface of the plug submerged in the recess, thus providing a pushing force to the plug. This pushing force increases the static friction between the plug and the inner wall of the recessed groove. Simultaneously, the increased static friction from the end deformation structure increases the force required to pull out the plug, providing a certain degree of anti-plugging effect.

[0043] One implementation involves a plug with a locking groove structure. The protrusion of the sliding plug can be inserted into the locking groove, but it does not contact the inner wall of the groove. When a force perpendicular to the plug is applied, the side of the plug with the locking groove contacts the protrusion against the inner wall of the groove, thus creating a limiting force. This unilateral limiting force increases the force exerted on the other side of the plug against the inner wall of the recess. If neither the plug nor the recess deforms, theoretically, the plug cannot be pulled out.

[0044] In the above-described embodiment with a locking groove, both the button and the sliding plug are engaged and limited by the housing of the electrical connector or other structures, and a resilient reset structure is provided at the corresponding position to provide a reset force. This embodiment further specifies, with reference to... Figures 1-9 The entire switch latch assembly also includes a press base, which is detachably mounted as an independent structure within the electrical connector.

[0045] The press base has a slot for limiting the linear movement of the button. A return spring and a latch are located within the slot. Locking grooves are located on the two opposite side surfaces of the button. These grooves are similar to the pressing mechanism of a ballpoint pen. The latch inserts into the groove to guide and limit the button's movement, creating a two-stage limiting pressing effect relative to the press base. Specifically, the button moves against the return force provided by the return spring towards the press base. Once it reaches the corresponding position, the latch and locking groove lock together. When the external force is removed, the button remains relatively fixed to the press base. The latch and locking groove unlock only when the button is pressed again.

[0046] Furthermore, it also includes a plug base, similar to a press base structure, for limiting the displacement of the sliding plug. It has a plug spring and a groove. The groove restricts the sliding plug to reciprocate in a straight line only in the direction of the plug, while the plug spring provides the sliding plug with a force that always moves away from the direction of the plug.

[0047] The sliding block has an inclined surface, and the button has a pressing end that contacts the inclined surface. When the button is pressed down, it moves against the sliding block in a direction perpendicular to the direction of button movement. Figure 4 The horizontal direction shown in the image.

[0048] Furthermore, the button has an indicator light inside, which is connected to the wiring in the electrical connector via a cable. This indicator light is generally a signal circuit used to provide feedback on the power-on status or the button's pressed status.

[0049] Furthermore, this embodiment also discloses a specific application method of the electrical connector, namely, as follows: Figures 1-9 The discharge connector structure shown is illustrated.

[0050] The power strip includes a socket body, which has a socket, a first through hole, and a second through hole. The first through hole is for the button to pass through, and the second through hole is for the sliding plug to pass through.

[0051] This utility model is not limited to the optional embodiments described above, and anyone can derive other various forms of products under the guidance of this utility model. The specific embodiments described above should not be construed as limiting the scope of protection of this utility model. The scope of protection of this utility model shall be determined by the claims, and the description can be used to interpret the claims.
