Description

Technical Field

[0001] The present invention relates to the field of detection devices, and particularly to a power supply performance detection device. Background Art

[0002] A power supply is a general term for power supply components. For example, components such as sockets and power strips in daily life can be collectively referred to as power supplies. When a socket or a power strip is working, household electrical appliances are electrically connected by inserting their plugs into the corresponding connection sockets. Among them, the connection sockets are generally of two-hole, three-hole and five-hole structures.

[0003] See Figure 1 , wherein safety doors are provided inside the connection sockets of the socket and the power strip. When the sub-sockets 01 connected to the live wire or the neutral wire are inserted and pressed, the safety doors are in a closed state, making it impossible for the plug to be normally inserted. This structure mainly prevents minors from using non-plug parts (such as metal wires) to insert into the connection sockets, causing electric shock hazards, so as to increase the safety of the socket and the power strip during electrical connection.

[0004] At the current stage, during the detection process after the production of sockets and power strips, operators also use a needle cone probe to single-press each sub-socket 01 position; however, for example, in some power strips, there are several groups of connection sockets provided. Using the single-press method, on the one hand, the detection work intensity is high; on the other hand, there is a phenomenon of missed detection easily. If the detection is not sufficient, it will affect the connection safety of the power supply device.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] See Figure 2 andFigure 3 , the present invention provides a power supply performance detection device, which includes a base body 1 and a contact group extending out of the base body 1 for inserting into a connection socket 00; the contact group has a number of sub-contacts 2, and the number and positions of the sub-contacts 2 are determined according to the type of the connection socket 00. For example, if the connection socket 00 has two ports, the number of sub-contacts 2 is two; if the connection socket 00 has three ports, the number of sub-contacts 2 is two; and if the connection socket 00 has five ports, the number of sub-contacts 2 is four (usually there is no safety door in the grounding socket 02 of the three-port and five-port connection sockets 00, so no detection is required). In this application, the case where the number of sub-contacts 2 is four is taken as an example.

[0028] See Figure 3 , to facilitate the position positioning of the sub-contacts 2 of the base body 1 and the corresponding connection socket 00, a position positioning structure is provided on the outer wall of the base body 1 of this application, which positions the contact group and the connection socket; this position positioning structure is an insertion piece 13. When the base body 1 is matched with a socket strip, only need to insert the insertion piece 13 into the grounding socket 02 in the connection socket 00 correspondingly.

[0029] A single contact driving structure and an overall driving structure are arranged inside the base body 1.

[0030] In the initial state (before entering the detection process), the sub-contacts 2 of the contact group are all in the contracted state. In this state, the positioning work of the insertion piece 13 is avoided from being affected.

[0031] In the first detection stage, the closed state of the safety door is detected, that is, after the connection socket 00 is subjected to non-combined pressing (single sub-contact 2 extends and presses), the safety door is in the closed state; during the detection, under the driving action of the single contact driving structure, a number of sub-contacts 2 extend and retract singly and orderly (after one sub-contact 2 completes the extension and retraction work, the next sub-contact 2 repeats until all sub-contacts 2 complete the work); when the sub-contact 2 extends, the safety door will block it, and the extension distance of the sub-contact 2 is limited. Among them, if the extension distance of the sub-contact 2 exceeds the predetermined distance, the safety door at this position is damaged.

[0032] In this embodiment, a rod body 3 is installed at the end of each sub-contact 2; the rod body 3 is slidably installed in the inner cavity of the base body 1. When the sub-contact 2 extends and contracts, the rod body 3 moves along its own axis direction.

[0033] See Figure 4 , and the single contact driving structure includes a pressure rod 4 rotatably installed around a fixed point in the inner cavity of the base body 1 and a driving member 5 for driving the pressure rod 4 to rotate; one end of the pressure rod 4 is connected to the rod body 3; after the angle of the pressure rod 4 changes ( Figure 4 as shown by the arrow), to drive the movement of the rod body 3.

[0034] See Figure 4 and Figure 8 , in order to ensure the single and orderly driving of the pressing rod 4 to rotate by the driving member 5 in this application, the driving member 5 is a turntable arranged at the center of a plurality of pressing rods 4, and a lifting protrusion 15 is arranged on the turntable to selectively push the pressing rod 4 to change the angle during the rotation of the turntable. During operation, the driving member 5 drives the lifting protrusion 15 to rotate. When the lifting protrusion 15 rotates to the position of the corresponding pressing rod 4, one end (driving end) of the pressing rod 4 is lifted to drive it to rotate. Of course, this application does not limit the structure of the above-mentioned driving member 5, and other structures that can achieve the single and orderly driving rotation of the pressing rod 4 are all acceptable.

[0035] In addition, the driving member 5 is coaxially connected to a rotating knob 9. When an operator operates, the rotating knob 9 is held and rotated (only 180° rotation is required), further realizing the rotation of the driving member 5.

[0036] The connection method between the end of the pressing rod 4 and the rod body 3 can adopt shaft hinge (the end of the pressing rod 4 is hinged at a predetermined position in the middle of the rod body 3), or as in this embodiment, a pressure plate 6 is arranged at a predetermined position in the middle of the rod body 3; a first reset member 7 for driving the rod body 3 to move and reset after the pressing rod 4 stops pressing is installed outside the rod body 3, and the first reset member 7 can be a straight spring; when driving the rod body 3 to move, the pressing end of the pressing rod 4 presses on the end face of the pressure plate 6.

[0037] See Figure 4 , Figure 5 , Figure 6 and Figure 7 , among which, the pressure plate 6 can be fixedly connected to the rod body 3 (such as an integrally formed structure), or as shown in this embodiment, in order to conveniently adjust the extending distance of the sub-contact 2 in the initial state and increase the extending length of the sub-contact 2 to adapt to different power supplies, a threaded structure is arranged on the outer wall of the rod body 3 ( Figure 6 shown); the pressure plate 6 is an annular disk-shaped structure with internal threads ( Figure 7 shown), and it is screwed onto the rod body 3; a guide rail 8 for rotationally positioning the pressure plate 6 is arranged in the inner cavity of the seat body 1, and the outer edge of the pressure plate 6 is installed in the guide rail 8 ( Figure 5 shown, a sliding groove cooperating with the guide rail 8 is arranged on the outer edge of the pressure plate 6), and the guide rail 8 can realize the rotational positioning of the pressure plate 6. During adjustment, only by rotating the rod body 3, the relative rotation between the rod body 3 and the pressure plate 6 can be realized, and under the action of the threaded structure (the threaded structure of this application adopts a self-locking thread with a small pitch, which can ensure that the relative position between the pressure plate 6 and the rod body 3 will not change after the pressure plate 6 is pressed), the position adjustment of the pressure plate 6 on the rod body 3 can be realized.

[0038] It should be further noted that, in addition to resetting the rod body 3, the first reset member 7 also plays a role in optimizing the detection steps. When observing the extension distance of the sub-contact 2 in the first detection stage, during the process of the limited extension distance of the sub-contact 2 (at this time, the first reset member 7 is compressed), if the safety door is damaged and suddenly released, the sub-contact 2 will produce a "click" abnormal sound due to the release of the first reset member 7. At this time, it can be indicated that the safety door at this position is damaged. After hearing the abnormal sound, it is possible to make a judgment result without observing the extension distance.

[0039] See Figure 4 and Figure 8 , in the second detection stage, the opening state of the safety door is detected. That is, after the connection socket 00 is subjected to combined pressing (the number of inserts of a plug component, in this embodiment, 4 sub-contacts 2 extend simultaneously), the safety door is in the open state; under the driving action of the overall driving structure, several sub-contacts 2 perform extension and retraction work as a whole. At this time, since the safety door can be normally opened, the sub-contacts 2 can normally extend a predetermined distance; if the extension distance of the sub-contacts 2 does not meet the requirements, it means that the safety door cannot enter the open state normally and further single detection is required.

[0040] Based on the above structure, the overall driving structure includes a pressing ring 10 that synchronously presses the pressing ends of a plurality of pressing rods 4 and a button 11 that drives the pressing ring 10 to move; the button 11 of the present application is arranged at the middle position of the rotating knob 9. The button 11 is driven by a second reset member 12 (the second reset member 12 can also be a straight spring, Figure 4 as shown) to reset after the external pressing force is removed. When operating, the operator only needs to press the button 11 to drive a plurality of pressing rods 4 to extend synchronously through the pressing ring 10 to detect the opening state of the safety door. If the safety door cannot enter the open state normally, the button 11 will be blocked and cannot be normally pressed.

[0041] When the device is in use, after inserting the insert 13 of the base body 1 into the corresponding connection socket 00, it is necessary to press the base body 1 with one hand while operating the device with the other hand to prevent the sub-contact 2 from lifting the base body 1 during the extension process. Or, an auxiliary clamping and fixing structure (not shown in the figure), such as a claw, is provided outside the base body 1 to assist in stabilizing its working state.

[0042] Certainly, the present invention can also have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding changes and deformations according to the present invention, but these corresponding changes and deformations should all fall within the protection scope of the appended claims of the present invention.
