Description

Technical Field

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

[0002] Power supply is a general term for power supply components, such as sockets and power strips in daily life. When the sockets and power strips are working, the household appliances are plugged into their corresponding connection sockets to achieve electrical connection. Among them, the connection sockets are generally two-port, three-port and five-port structures.

[0003] See also Figure 1 Among them, a safety door is provided inside the connection socket of the socket and the strip. When the sub-socket 01 connected to the live wire or the neutral wire is inserted and pressed, the safety door is in a closed state, so that the plug cannot be inserted normally. This structure is mainly to prevent minors from using non-plug parts (such as metal wires) to insert into the connection socket, causing the risk of electric shock, so as to increase the safety of the electrical connection of the socket and the strip.

[0004] At present, during the inspection process of sockets and power strips after production, operators also use a needle cone probe to press each sub-socket 01 position. However, for example, some power strips have several groups of connection sockets, and the single-press method has high inspection intensity on the one hand; on the other hand, it is easy to miss the inspection. If the inspection is not sufficient, it will affect the connection safety of the power supply equipment.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below 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 intended to limit the present invention.

[0019] See also Figure 2 and Figure 3The present invention provides a power supply performance detection device, which includes a base body 1, a contact group extending from the base body 1 and used for being inserted into a connection socket 00; the contact group has a plurality of sub-contacts 2, and the number and position 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 the sub-contacts 2 is two; if the connection socket 00 has three ports, the number of the sub-contacts 2 is two; and if the connection socket 00 has five ports, the number of the sub-contacts 2 is four (usually, a safety door is not provided in the grounding socket 02 in the three-port and five-port connection sockets 00, so no detection is required). This application takes four sub-contacts 2 as an example.

[0020] See also Figure 3 In order to facilitate the positioning of the sub-contact 2 of the seat body 1 and the corresponding connecting socket 00, the outer wall of the seat body 1 of the present application is provided with a positioning structure, which positions the contact group and the connecting socket; the positioning structure is a plug 13. When the seat body 1 is matched with the socket strip, it is only necessary to insert the plug 13 into the grounding socket 02 in the connecting socket 00.

[0021] A single contact driving structure and an overall driving structure are arranged inside the seat body 1 .

[0022] In the initial state (before entering the detection process), the sub-contacts 2 of the contact group are all in a retracted state, in which case the positioning of the insert 13 is not affected.

[0023] In the first detection stage, the closed state of the safety door is detected, that is, after the connection socket 00 is pressed in a non-combination manner (a single sub-contact 2 is extended and pressed), the safety door is in a closed state; during the detection, under the driving action of the single contact driving structure, a number of sub-contacts 2 are extended and retracted in a single and orderly manner (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); during the extension process of the sub-contact 2, 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 that position is damaged.

[0024] In this embodiment, a rod 3 is installed at the end of each sub-contact 2; the rod 3 is slidably installed in the inner cavity of the seat body 1, and when the sub-contact 2 is extended or retracted, the rod 3 moves along its own axis.

[0025] See also Figure 4 , and the single contact driving structure includes a pressure rod 4 installed in the inner cavity of the seat body 1 and a driving member 5 driving the pressure rod 4 to rotate around a fixed point; 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), the rod body 3 is driven to move.

[0026] See also Figure 4 and Figure 8 In order to ensure that the driving member 5 drives the pressure rod 4 to rotate in a single and orderly manner, the driving member 5 is a turntable arranged at the center of the plurality of pressure rods 4, and the turntable is provided with a lifting protrusion 15 which selects one of the pressure rods 4 to change its angle during the rotation of the turntable. During operation, the driving member 5 drives the lifting protrusion 15 to rotate, and when the lifting protrusion 15 rotates to the corresponding position of the pressure rod 4, one end (driving end) of the pressure rod 4 is lifted to drive it to rotate. Of course, the present application is not limited to the above-mentioned driving member 5 structure, and other structures can realize the single and orderly driving and rotating work of the pressure rod 4.

[0027] In addition, the driving member 5 is coaxially connected to a rotating knob 9. When the staff operates, they hold the rotating knob 9 and rotate it (180° is sufficient) to further realize the rotation of the driving member 5.

[0028] The connection method between the end of the pressure rod 4 and the rod body 3 can be an axial hinge (the end of the pressure rod 4 is hinged at a predetermined position in the middle of the rod body 3), or as in the present embodiment, a pressure plate 6 is provided at a predetermined position in the middle of the rod body 3; a first reset member 7 is installed outside the rod body 3 to drive the rod body 3 to move and reset after the pressure of the pressure rod 4 is lost, wherein the first reset member 7 can be a straight spring; when the rod body 3 is driven to move, the pressing end of the pressure rod 4 presses on the end face of the pressure plate 6.

[0029] See also Figure 4 , Figure 5 , Figure 6 and Figure 7 , wherein the pressure plate 6 can be fixed to the rod body 3 (such as an integrally formed structure), or as shown in this embodiment, in order to facilitate the adjustment of the extension distance of the sub-contact 2 in the initial state and increase the extension length of the sub-contact 2 to adapt to different power supplies, the outer wall of the rod body 3 is provided with a threaded structure ( Figure 6 The pressure plate 6 is an annular disc structure with internal threads ( Figure 7 As shown), which is screwed onto the rod body 3; the inner cavity of the seat body 1 is provided with a guide rail 8 for rotating and positioning the pressure plate 6, and the outer edge of the pressure plate 6 is installed in the guide rail 8 ( Figure 5 As shown, the outer edge of the pressure plate 6 is provided with a slide groove that cooperates with the guide rail 8), and the guide rail 8 can realize the rotation positioning of the pressure plate 6. When adjusting, it is only necessary to rotate the rod body 3 to realize the relative rotation between the rod body 3 and the pressure plate 6. Under the action of the thread structure (the thread structure of the present 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 is realized.

[0030] It should be further explained that, in addition to resetting the rod body 3, the first reset member 7 also plays a role in optimizing the detection steps. When the extension distance of the sub-contact 2 is observed in the first detection stage, the extension distance of the sub-contact 2 is limited (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 an abnormal "click" 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, the judgment result can be made without observing the extension distance.

[0031] See also 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 pressed in combination (the number of plugs of a plug component, in this embodiment, 4 sub-contacts 2 are extended at the same time), the safety door is in the open state; under the driving action of the overall driving structure, a number of sub-contacts 2 are extended and retracted as a whole. At this time, since the safety door can be opened normally, the sub-contact 2 can be extended normally to a predetermined distance; if the extension distance of the sub-contact 2 does not meet the requirement, it means that the safety door cannot enter the open state normally, and further single detection is required.

[0032] Based on the above structure, the overall driving structure includes a pressing ring 10 for synchronously pressing the pressing ends of the multiple pressing rods 4 and a button 11 for driving the pressing ring 10 to move; the button 11 of the present application is arranged at the middle position of the rotating knob 9. After the button 11 loses the external force pressing, it is supported by the second reset member 12 (the second reset member 12 can also be a straight spring, Figure 4 When operating, the operator only needs to press the button 11 to drive the multiple pressure rods 4 to extend synchronously through the pressure ring 10 to detect the opening state of the safety door. If the safety door cannot enter the opening state normally, the button 11 is blocked and cannot be pressed normally.

[0033] When the device is in use, after inserting the insert 13 of the seat body 1 into the corresponding connection socket 00, the seat body 1 needs to be pressed by one hand while the other hand operates the device to prevent the sub-contact 2 from lifting the seat body 1 during the extension process. Alternatively, a clamping and fixing structure (not shown in the figure) is provided outside the seat body 1 to assist in stabilizing its working state, such as a claw.

[0034] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
