A single-pressure-proof hole-free socket

Abstract

A socket without holes that is resistant to single pressure belongs to the technical field of sockets and solves the technical problem of the anti-single pressure function of the socket without holes. The solution is: the protection door assembly includes a protection door shaft, a protection door and a cam, and the protection door shaft is installed on the socket cover shell; the rotating conductive sheet installation assembly includes a rotating frame shaft, a rotating frame and a rotating conductive sheet, and an anti-single pressure slider is arranged above the partition frame between the rotating conductive sheet installation assemblies on both sides. The anti-single pressure slider slides forward and backward along the partition frame or rotates around the partition frame. The pin drives the cam to rotate through the protection door rotation, and the cam drives the anti-single pressure slider to slide backward along the partition frame. The anti-single pressure slider drives the rotating conductive sheet installation assembly to rotate, and the rotating conductive sheet rotates toward the corresponding fixed conductive sheet side. The present invention adds an anti-single pressure slider, so that the anti-single pressure slider drives the rotating conductive sheet installation assembly to rotate at the same time, thereby avoiding the contact between the fixed conductive sheet on the side where the pin is not inserted and the rotating conductive sheet, so that the socket without holes has the anti-single pressure function.

Description

Technical Field

[0001] The invention belongs to the technical field of sockets, and particularly relates to a single-pressure-proof holeless socket. Background Art

[0002] In the prior art, ordinary sockets have leaky holes, which not only causes dust to enter the sockets, but more dangerously, since children's height is comparable to that of some sockets, it is easy for children to put their hands into the sockets, causing a risk of electric shock. The Chinese patent "branch-conductor holeless socket" (patent number: 2013100924518) solves the above problems well, and branch-conductor holeless sockets are also accepted and used by everyone.

[0003] However, with the continuous improvement of people's quality of life, the country has proposed that sockets should have the function of preventing single pressure. Because in the prior art, when a pin on the plug is inserted into the socket alone, it is easy to cause the fixed conductive sheet on the side where the pin is not inserted to contact with the rotating conductive sheet, causing a short circuit in the circuit and posing a safety hazard to electricity use. Therefore, it is imperative to have a hole-less socket that prevents single pressure. However, there is no technical solution in the prior art that can solve the problem of the function of preventing single pressure in a hole-less socket. Summary of the invention

The other end of the second return spring is fixedly connected to the fixing column. The rotating conductive sheet is fixedly installed at the head end of the rotating frame. A limiting slider is arranged above the tail end of the rotating frame.

[0010] An anti-single-pressure slider is arranged above the bulkhead between the rotating conductive sheet mounting assemblies on both sides, the axial direction of the anti-single-pressure slider is perpendicular to the length direction of the bulkhead below the anti-single-pressure slider, a semicircular groove is arranged in the middle of the bottom surface of the anti-single-pressure slider, the upper surface of the bulkhead is mounted in the semicircular groove, the anti-single-pressure slider slides back and forth along the bulkhead or rotates around the bulkhead, the limit slider cooperates with the rear side surface of the anti-single-pressure slider, when the pin is inserted into the socket base from the jack, the protective door rotates to drive the cam to rotate, the cam drives the anti-single-pressure slider to slide backward along the bulkhead, and the anti-single-pressure slider The block drives the rotating conductive sheet installation assembly to rotate through the limiting slider, and the rotating conductive sheet rotates toward the corresponding fixed conductive sheet, and the rotating conductive sheet and the corresponding fixed conductive sheet clamp the pin, and the pin and the socket are in an electrically conductive state; the rear side surface of the anti-single pressure slider is symmetrically provided with a third return spring fixing pit on both sides of the semicircular groove, and a third return spring fixing seat is vertically upwardly provided on the socket base behind the partition frame, one end of the third return spring is installed on the third return spring fixing seat, and the other end of the third return spring is installed in the third return spring fixing pit.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The rotating conductive sheet installation assembly includes a rotating frame shaft 51, a rotating frame 52 and a rotating conductive sheet 53. The rotating frame shaft 51 is vertically installed at the four corners of the socket base 1. A fixing column 54 is arranged on the outer side of the rotating frame shaft 51. The middle part of the rotating frame 52 is installed on the rotating frame shaft 51. One end of the second return spring 55 is fixedly connected to the tail end of the rotating frame 52. The other end of the second return spring 55 is fixedly connected to the fixing column 54. The rotating conductive sheet 53 is fixedly installed at the head end of the rotating frame 52. A limit slider 56 is arranged above the tail end of the rotating frame 52.

[0028] An anti-single-pressure slider 6 is arranged above the bulkhead 41 between the rotating conductive sheet mounting assemblies on both sides, the axial direction of the anti-single-pressure slider 6 is perpendicular to the length direction of the bulkhead 41 below the anti-single-pressure slider 6, a semicircular groove 61 is arranged in the middle of the bottom surface of the anti-single-pressure slider 6, the upper surface of the bulkhead 41 is installed in the semicircular groove 61, the anti-single-pressure slider 6 slides back and forth along the bulkhead 41 or rotates around the bulkhead 41, the limit slider 56 cooperates with the rear side of the anti-single-pressure slider 6, when the pin is inserted into the socket base 1 from the jack, the cam 33 is driven to rotate by the protective door 32, and the cam 33 drives the anti-single-pressure slider 6 to slide backward along the bulkhead 41, The anti-single-pressure slider 6 drives the rotating conductive sheet installation assembly to rotate through the limiting slider 56, and the rotating conductive sheet 53 rotates toward the corresponding fixed conductive sheet 42. The rotating conductive sheet 53 and the corresponding fixed conductive sheet 42 clamp the pin, and the pin and the socket are in an electrically conductive state; the rear side surface of the anti-single-pressure slider 6 is symmetrically provided with third return spring fixing pits 62 on both sides of the semicircular groove 61, and a third return spring fixing seat 7 is vertically upwardly provided on the socket base 1 behind the partition frame 41, one end of the third return spring 8 is installed on the third return spring fixing seat 7, and the other end of the third return spring 8 is installed in the third return spring fixing pit 62.

[0031] The use process of the present invention is as follows:

[0032] When the two or three pins of the plug are inserted into the socket at the same time (i.e. normal use):

[0033] The pin passes through the hole blocking plate 34 and the protection door 32 in sequence, and synchronously drives the cam 33 to rotate around the protection door shaft 31. The cam 33 simultaneously drives the anti-single pressure slider 6 to slide along the partition frame 42. The anti-single pressure slider 6 drives the rotating frame 52 to rotate through the limit slider 6, so that the rotating conductive sheet installation assembly rotates around the rotating frame axis 51 to be opposite to the fixed conductive sheet installation assembly. The rotating conductive sheet installation assembly and the corresponding fixed conductive sheet installation assembly clamp the inserted pin, and the plug and the socket are in an electrically conductive state.

[0034] When one of the pins is inserted into the socket (i.e. single pressure protection state):

[0035] The pin inserted into the socket also drives the cam 33 to rotate around the protection door shaft 31 through the blocking plate 34 and the protection door 32 in sequence. However, the rotating cam 33 causes the anti-single pressure slider 6 to rotate around the partition frame 42, and the anti-single pressure slider 6 cannot slide through the limit slider 6 to drive the rotating frame 52 to rotate. Although one of the pins is inserted into the socket, the pin and the socket are electrically disconnected, that is, the socket has the anti-single pressure function.

[0036] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the protection scope of the claims.
