Description

Technical Field

[0001] This invention relates to the field of power connector technology, and more particularly to a power connector plug that can be manually switched on and off. Background Technology

[0002] A power connector typically includes a plug and a socket that is plugged into the plug. The socket is located inside an external chassis (electronic equipment with an internal power supply). The plug is connected to an external load via an external cable. When the plug is inserted into the socket, power can be supplied to the external load.

[0003] In existing technology, the terminals of power connector plugs are basically fixed inside the plug, meaning that the terminals cannot move relative to each other, and all terminals can only be inserted and removed as a whole with the plug. When the plug is inserted into the socket or removed from the socket, the presence of an electric arc can cause arcing and other damage to the contacts due to the presence of an electric arc while the plug is energized. Summary of the Invention

[0004] The purpose of this invention is to provide a power connector plug that can be manually switched. By setting a manual switch component, before the plug is inserted or removed, the movable terminal is moved by pulling the manual switch component, so that the movable terminal disconnects the conductive circuit with the socket, thereby avoiding safety risks such as arcing and sparking.

[0005] To achieve the above objectives, the following technical solution is adopted:

[0006] A manually switchable power connector plug includes a plug housing, a wiring housing disposed within the plug housing, and a wiring terminal module disposed within the wiring housing; the wiring terminal module includes at least one movable terminal assembly for use as a non-grounded terminal; the movable terminal assembly includes a movable terminal movable along the length of the plug, and an adapter fixing member conductively contacting the movable terminal; the movable terminal is used for conductive connection with a socket, and the adapter fixing member is used for connecting an external cable; each movable terminal is driven by a manual switch assembly to move along the length of the plug to achieve conductive connection with the socket on or off.

[0008] Preferably, the adapter is fixedly installed inside the wiring housing, and multiple conductive contact protrusions are provided between the movable terminal and the adapter; the movable terminal and the adapter achieve contact conductivity through the multiple conductive contact protrusions.

[0009] Preferably, one side of the adapter fixing member is located between the first end of the movable terminal and the inner wall of one side of the wiring housing; the adapter fixing member has a first sliding groove hole along the length direction of the plug, and the side wall of the wiring housing has a second sliding groove hole corresponding to the first sliding groove hole; when the pull rod moves along the length direction of the plug, the connecting shaft slides in the first sliding groove hole and the second sliding groove hole to drive the movable terminal to move.

[0010] Preferably, the inner wall of the wiring housing is provided with a first limiting groove for limiting the adapter fixing component.

[0011] Preferably, the inner wall of the wiring housing is further provided with a second limiting groove, which is located on the side of the first limiting groove away from the inner wall of the wiring housing; the second limiting groove is connected to the first limiting groove, and the second limiting groove is used to limit the first end of the movable terminal.

[0012] Preferably, the outer wall of the wiring housing corresponding to the first limiting groove is provided with a movable guide groove for guiding the first end of the pull rod to slide.

[0013] Preferably, the cross-section of the adapter fixing member is L-shaped; the first sliding groove hole is opened at the L-shaped vertical end of the adapter fixing member, and the L-shaped horizontal end of the adapter fixing member is arranged below the first end of the movable terminal.

[0014] Preferably, the contact conductive protrusion is integrally formed on the first end of the movable terminal.

Simultaneously, the adapter is securely installed inside the wiring housing for easy connection of external cables. Furthermore, multiple conductive contact protrusions on the movable terminal ensure constant conductive contact between the movable terminal and the adapter, guaranteeing reliable conductivity.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0035] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0036] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0038] Reference Figures 1 to 7 As shown, this invention provides a manually switchable power connector plug, including a plug housing 1, a wiring housing 2 disposed within the plug housing 1, and a wiring terminal module disposed within the wiring housing 2. The wiring terminal module includes at least one movable terminal assembly used as a non-grounded terminal. Since the grounding terminal needs to conduct first when the plug and socket are inserted and conducting electricity, and the grounding terminal needs to disconnect last when the conductive connection between the plug and socket is broken, the grounding terminal must disconnect last to ensure reliable grounding. Therefore, the power connector plug of this invention can include two-core, three-core, four-core, and five-core power connector plugs, as long as the movable terminal assembly is used as the non-grounded terminal.

[0039] The movable terminal assembly includes a movable terminal 3 that can move along the length of the plug, and an adapter fixing member 4 that is in contact with the movable terminal 3 and conducts electricity; the second end of the movable terminal 3 is conductively connected to the socket, and the adapter fixing member 4 is used to connect an external cable.

[0040] When the power connector is a two-pin connector, including a positive terminal and a negative terminal, as long as the conductive circuit between either the positive or negative terminal and the socket is broken, plugging and unplugging without power can be achieved. Movable terminal assemblies can be used as either positive or negative terminals; that is, movable terminal assemblies can replace the original fixed positive or negative terminals, or each positive and negative terminal can be replaced by a separate movable terminal assembly. Please continue to refer to... Figure 3In one specific embodiment, the movable terminal assembly is used as the positive or negative terminal, and the other terminal not replaced by the movable terminal assembly is set as a non-movable terminal, i.e., fixed terminal 12.

[0041] Each movable terminal 3 is driven by a manual switch assembly 5 to move along the length of the plug to achieve conductive connection with the socket. The manual switch assembly 5 includes a connecting shaft 51 connected to the first end of the movable terminal 3, and a pull rod 52 connected to the connecting shaft 51; the first end of the pull rod 52 is connected to the connecting shaft 51, and the second end of the pull rod 52 extends to the outside of the plug housing 1. The second end of the pull rod 52 is provided with a pull ring 53, which facilitates manual pulling of the pull rod 52.

[0042] The adapter fixing component 4 is fixedly installed inside the wiring housing 2, and multiple contact conductive protrusions 6 are provided between the movable terminal 3 and the adapter fixing component 4 at intervals. The contact conductive protrusions 6 are integrally formed on the first end of the movable terminal 3; the movable terminal 3 and the adapter fixing component 4 achieve contact conductivity through the multiple contact conductive protrusions 6.

[0043] One side of the adapter fixing component 4 is located between the first end of the movable terminal 3 and the inner wall of one side of the wiring housing 2; the adapter fixing component 4 has a first sliding groove hole 7 along the length direction of the plug, and the side wall of the wiring housing 2 has a second sliding groove hole 8 corresponding to the first sliding groove hole 7; the connecting shaft 51 passes through the second sliding groove hole 8 and the first sliding groove hole 7 and is riveted to the first end of the movable terminal 3, and cooperates with the pull rod 52 to realize the back and forth movement of the movable terminal 3. When the pull rod 52 moves along the length direction of the plug, the connecting shaft 51 slides in the first sliding groove hole 7 and the second sliding groove hole 8 to drive the movable terminal 3 to move.

[0044] The inner wall of the wiring housing 2 is provided with a first limiting groove 9 for limiting the adapter fixing component 4. The inner wall of the wiring housing 2 is also provided with a second limiting groove 10, which is located on the side of the first limiting groove 9 away from the inner wall of the wiring housing 2; the second limiting groove 10 is connected to the first limiting groove 9 and is used to limit the first end of the movable terminal 3.

[0045] A movable guide groove 11 is provided on the outer wall of the wiring housing 2 corresponding to the first limiting groove 7, for guiding the first end of the pull rod 52 to slide. The movable guide groove 11 is provided along the length direction of the plug, and a guide block 54 is provided at the first end of the pull rod 52 to cooperate with the movable guide groove 11. When the pull rod 52 is pulled, the guide block 54 moves along the guide path of the movable guide groove 11, thereby allowing the connecting shaft 51 to slide in the first sliding hole 7 and the second sliding hole 8, so that the movable terminal 3 can move forward to achieve conductive connection with the socket, or move backward to disconnect the conductive connection with the socket.

[0046] The cross-section of the adapter fixing member 4 is L-shaped; the first sliding groove hole 7 is opened at the L-shaped vertical end of the adapter fixing member 4, the L-shaped vertical end of the adapter fixing member 4 and the first end of the movable terminal 3 form a stacked arrangement structure, and the L-shaped horizontal end of the adapter fixing member 4 is located below the first end of the movable terminal 3. The overall structure is stable and compact.
