Description

Technical Field

[0001] The utility model relates to the technical field of sockets, in particular to an anti-misinsertion socket. Background Art

[0002] In order to ensure the safety of residential electricity use, traditional anti-misinsertion sockets will add a block with an inclined surface and a spring between the panel and the metal sheet. The block is used to prevent children's fingers from inserting into the jack. When the plug is inserted, the block is opened through the guidance of the inclined surface to meet the normal power supply of the plug and compress the spring. When the plug is removed, the block is reset by the action of the spring. However, such a structure still has deficiencies. For example, when a sharp object is inserted into the jack by hand, the block will still open, causing electric shock to the human body. Therefore, the traditional anti-misinsertion socket cannot prevent sharp objects from being inserted into the jack, and there is still a potential safety hazard in electricity use. Summary of the Invention

[0003] In order to overcome the deficiencies of the background art, the technical solution adopted by the utility model is: an anti-misinsertion socket, including a base, a metal sheet, a jack panel, an upper block, a lower block and a spring. The base is provided with a wiring groove and a card slot arranged around the wiring groove. The metal sheet is connected in the wiring groove. The jack panel is clamped to the base through the card slot. The jack panel is provided with an upper sliding groove and a lower sliding groove for accommodating the upper block and the lower block. The spring is arranged between the jack panel and the upper block / lower block. Two groups of symmetrically distributed first guiding surfaces are arranged on the front surface of the upper block, and a first arc groove is arranged on the back surface between adjacent first guiding surfaces. The wiring groove is provided with an upper partition corresponding to the first arc groove. The upper block is slidably connected between the upper sliding groove and the upper partition. Anti-unidirectional misinsertion blocking strips are symmetrically distributed in the upper sliding groove; the lower block is provided with a second guiding surface and flat blocking surfaces arranged on both sides of the second guiding surface. The wiring groove is provided with two lower partitions abutted against the lower block. The lower block is slidably connected between the lower sliding groove and the lower partition.

[0004] By adopting the above technical solution, when a two-pin plug is inserted normally, the upper block is evenly stressed on both sides, so that the upper block is always parallel to the jack panel. Through the guidance of the first guiding surface, the upper block can move and open normally. When a sharp object is inserted into the two-pin jack, the sharp object will touch the first guiding surface of the upper block, and the upper block will rotate slightly relative to the upper partition. A corner of the upper block rotates above the blocking strip, making the upper block unable to move downward, thus preventing the sharp object from touching the metal sheet; when a three-pin plug is inserted normally, since the ground wire end of the three-pin plug is longer than the zero and live ends, the ground wire end is preferentially clamped into the second guiding surface, and the lower block can move and open normally. When a sharp object is inserted into the zero and live ends of the three-pin jack, it cannot touch the metal sheet due to the blocking of the flat blocking surface, thus avoiding electric shock caused by misinsertion and improving the safety of electricity use.

[0005] The utility model is further configured such that the first guide surface is an inclined surface inclined upward toward the direction of the metal sheet, and the second guide surface is an inclined surface inclined downward toward the direction of the metal sheet; by designing the inclination direction of the first guide surface and the second guide surface, the direction in which the upper block / lower block moves due to force is controlled, and the structure is simple and the design is reasonable.

[0006] The utility model is further configured such that the outer side surface of the upper partition is an arc surface, the first arc groove is tangent to the upper partition, the jack panel is provided with a second arc groove, and the upper block is provided with a protrusion tangent to the second arc groove; when the upper block rotates, the front and back surfaces of the upper block are always tangent to the upper partition and the jack panel, so that the rotation is natural and there is no jamming.

[0007] The utility model is further configured such that the upper block is provided with a first T-shaped slot for clamping the spring, and the jack panel is provided with a first connecting column corresponding to the first T-shaped slot; one end of the spring is partially compressed and clamped into the first T-shaped slot to fix the spring, thereby preventing the spring from detaching from the upper block during installation, so as to improve installation efficiency.

[0008] The utility model is further configured such that the jack panel is provided with a mounting portion at the ground wire interface, the mounting portion is provided with a second T-shaped slot for clamping the spring, the lower stopper is provided with a rectangular slot for accommodating the mounting portion, and a second connecting column corresponding to the second T-shaped slot, and the flat blocking surface is provided on both sides of the rectangular slot; one end of the spring is partially compressed and clamped into the second T-shaped slot to fix the spring, so as to prevent the spring from detaching from the jack panel during installation, so as to improve installation efficiency.

[0009] The utility model is further configured such that the jack panel is provided with a clamping portion for clamping the card slot, and an extension portion connected to the clamping portion, the clamping portion is in a U-shape as a whole; the direction of the extension portion is the same as the outer surface of the jack panel, and the jack panel can be opened by simply moving the extension portion, thereby improving the convenience of repairing the socket.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] When a sharp object is inserted into a two-pin socket, the sharp object will touch the first guide surface of the upper block, and the upper block will rotate slightly relative to the upper partition, and one corner of the upper block will rotate to the top of the baffle, so that the upper block cannot move downward, thereby preventing the sharp object from touching the metal sheet; when a sharp object is inserted into the zero and live ends of the three-pin socket, it can avoid electric shock due to misinsertion, thereby improving electrical safety.

[0022] Such as Figures 1-6As shown in the figure, this embodiment provides an anti-misinsertion socket, which includes a base 1, a metal sheet 2, a jack panel 3, an upper stopper 4, a lower stopper 5 and a spring 6. The base 1 is provided with a wiring groove 11 and card slots 12 arranged around the wiring groove 11. The metal sheet 2 is threadedly connected to the wiring groove 11 through screws at the wiring end. The jack panel 3 is snap-connected to the base 1 through the card slots 12. The jack panel 3 is provided with an upper sliding groove 31 and a lower sliding groove 32 for accommodating the upper stopper 4 and the lower stopper 5. The spring 6 is arranged between the jack panel 3 and the upper stopper 4 / lower stopper 5. The front surface of the upper stopper 4 is provided with two groups of symmetrically distributed first guiding surfaces 41, and the back surface is provided with a first arc groove 42 located between adjacent first guiding surfaces 41. The wiring groove 11 is provided with an upper partition 13 corresponding to the first arc groove 42. The upper stopper 4 is slidably connected between the upper sliding groove 31 and the upper partition 13. The upper sliding groove 31 is symmetrically distributed with blocking bars 33 for preventing one-way misinsertion; the lower stopper 5 is provided with a second guiding surface 51 and flat blocking surfaces 52 arranged on both sides of the second guiding surface 51. The wiring groove 11 is provided with two lower partitions 14 abutting against the lower stopper 5. The lower stopper 5 is slidably connected between the lower sliding groove 32 and the lower partitions 14.

[0023] In this embodiment, the first guiding surface 41 is an inclined surface that slopes upward in the direction towards the metal sheet 2, the second guiding surface 51 is an inclined surface that slopes downward in the direction towards the metal sheet 2. The outer side surface of the upper partition 13 is an arc surface. The first arc groove 42 is tangent to the upper partition 13. The jack panel 3 is provided with a second arc groove 34. The upper stopper 4 is provided with a protrusion 43 tangent to the second arc groove 34. The upper stopper 4 is provided with a first T-shaped groove 44 for snap-connecting the spring 6. The jack panel 3 is provided with a first connecting column 35 corresponding to the first T-shaped groove 44. The jack panel 3 is provided with an installation portion 36 at the ground wire interface. The installation portion 36 is provided with a second T-shaped groove 37 for snap-connecting the spring 6. The lower stopper 5 is provided with a rectangular groove 53 for accommodating the installation portion 36 and a second connecting column 54 corresponding to the second T-shaped groove 37. The flat blocking surfaces 52 are arranged on both sides of the rectangular groove 53. The jack panel 3 is provided with a snap-connecting portion 38 for snap-connecting the card slots 12 and an extension portion 39 connected to the snap-connecting portion 38. The snap-connecting portion 38 is integrally U-shaped.

[0024] Combined with Figure 7 、 8As shown in the figure, the working principle of the present utility model is as follows. When a two-pin plug is normally inserted, the upper stop block 4 is evenly stressed on both sides, so that the upper stop block 4 is always parallel to the jack panel 3. Under the guidance of the first guiding surface 41, the upper stop block 4 can move downward normally to open, and the spring 6 is compressed to facilitate the normal insertion of the two-pin plug. After the two-pin plug is pulled out, the upper stop block 4 resets. When a sharp object is inserted into the two-pin jack, the sharp object will touch the first guiding surface 41 of the upper stop block 4, and the upper stop block 4 will rotate slightly relative to the upper partition 13, and a corner of the upper stop block 4 rotates above the stop bar 33, so that the upper stop block 4 cannot move downward, thus preventing the sharp object from touching the metal sheet 2. When a three-pin plug is normally inserted, since the ground wire end of the three-pin plug is longer than the neutral and live ends, the ground wire end is preferentially clamped into the second guiding surface 51, and the lower stop block 5 can move downward normally to open, and the spring 6 is compressed to facilitate the normal insertion of the three-pin plug. After the three-pin plug is pulled out, the lower stop block 5 resets. When a sharp object is inserted into the neutral and live ends of the three-pin jack, it cannot touch the metal sheet 2 due to the blockage of the flat blocking surface 52, thus preventing electric shock caused by misinsertion and improving the electrical safety.

[0025] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
