Detailed Description

For the purposes of making the objects, technical solutions and advantages of the embodiments of the present application more clear, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. The components of the embodiments of the present application, which are generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the present application, as provided in the accompanying drawings, is not intended to limit the scope of the application, as claimed, but is merely representative of selected embodiments of the application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

In the description of the present application, it should be noted that terms such as "top" and "top" are used to refer to the top surface of the side of the receptacle of the present application that faces upward in the use state, and the bottom surface of the side that faces downward; the use of terms such as "first" and "second" is for the purpose of distinguishing between similar elements and not necessarily for the purpose of indicating or implying any particular importance or order of such elements; terms such as "inner", "outer" and "inner and outer" are used to refer to specific contours. The above terms are used only for the sake of clarity and simply to describe the technical solutions of the present application, and should not be construed as limiting the present application.

Firstly, it should be noted that, in practical application, the protection of the socket is mainly to avoid the problem of electric shock caused by that a child stretches fingers or elongated conductive objects into the jack (i.e. the through hole provided on the panel) of the socket, but the following problems still exist in the existing socket: firstly, the structure of the shielding sheet is complex, the blocking is easy to occur, and the insertion is inconvenient; on the other hand, when the existing socket is not used, the power supply is still communicated with the plug bush in the socket, so that the plug bush in the socket is still electrified, and the risks of electric leakage and electric shock still exist.

The following describes the technical scheme of the present application in detail with reference to the accompanying drawings.

Example 1

As shown in fig. 1 to 15, the present embodiment provides a socket 100, which includes a panel 1 and a housing 2, wherein the panel 1 and the housing 2 together enclose a receiving cavity 3, and a through hole 11 into which an electrical contact 201 of a plug is inserted is formed in the panel 1; the socket 100 further comprises a plug bush assembly 4, a first conductive piece 5 and a second conductive piece 6 which are respectively arranged in the accommodating cavity 3, wherein the first conductive piece 5 is used for being electrically connected with a power supply, the second conductive piece 6 is used for being electrically connected with the electric contact 201, and the first conductive piece 5 and the second conductive piece 6 are arranged at intervals; the plug bush assembly 4 comprises a pressing cavity 41 and a plate body 42, wherein the pressing cavity 41 is used for inserting the power contact 201, the plate body 42 is movably arranged between the pressing cavity 41 and the second conductive piece 6, and the second conductive piece 6 is movably arranged between the first conductive piece 5 and the plate body 42; and, the plate body 42 is configured to be able to push the second conductive member 6 into conductive contact with the first conductive member 5 when the electrical contact 201 is inserted into the pressing chamber 41.

Through above-mentioned technical scheme, the plate body 42 that this application set up can be after the electric contact 201 of plug inserts extrusion chamber 41, can rely on the extrusion force that produces to plate body 42 when electric contact 201 inserts to make plate body 42 can promote second electrically conductive piece 6 and first electrically conductive piece 5 conductive contact to realize switching on of circuit. On the one hand, the socket 100 of the present application has a simple structure, and no problem of insertion jamming, so that the insertion operation is very convenient; on the other hand, when the electrical contact 201 of the plug is not inserted, the first conductive member 5 and the second conductive member 6 are not in contact (i.e., are disposed at intervals) in the socket 100, so that the power supply and the second conductive member 6 are not conducted, and therefore, when the plug is not inserted, the plug housing in the socket 100 is not electrified, and the problems of electric leakage and electric shock of the socket 100 can be effectively avoided. Therefore, the safety of the socket 100 can be reliably improved on the basis of improving the inserting convenience of the socket 100, so that the problems of electric leakage and electric shock can be avoided as much as possible.

In the above embodiment, it is understood that the width of the extrusion chamber 41 (i.e., the width of the extrusion chamber 41 into which the power contact 201 is inserted in the cross-sectional view of fig. 2) may be selected according to actual needs. For example, as shown in fig. 2 and 3, in the case where the pressing chamber 41 is relatively regular, the width of the pressing chamber 41 may be approximately zero (in this case, the moving distance of the plate 42 after the insertion of the electrical contact 201 is approximately equal to the thickness of the electrical contact 201), or may be slightly smaller than the thickness of the electrical contact 201 (in this case, the moving distance of the plate 42 after the insertion of the electrical contact 201 is approximately equal to the difference between the thickness of the electrical contact 201 and the width of the pressing chamber 41). In addition, in the case where the pressing chamber 41 is configured to be relatively irregular, the width and shape of the pressing chamber 41 are not particularly limited in this application as long as the electrical contact 201 of the plug can push the plate body 42 toward the movement after being inserted into the pressing chamber 41.

Furthermore, it should be noted that, in the above embodiment, the meaning that the plate body 42 of the present application is movably disposed between the pressing chamber 41 and the second conductive member 6 includes: the plate 42 is movably or rotatably arranged between the pressing chamber 41 and the second conductive member 6, so long as the plate 42 can be pushed to move toward the second conductive member after the electric contact 201 is inserted into the pressing chamber 41, so that the second conductive member can be in conductive contact with the first conductive member. Similarly, the meaning of the second conductive member 6 of the present application being movably disposed between the first conductive member 5 and the plate body 42 includes: the second conductive member 6 is movably or rotatably disposed between the first conductive member 5 and the plate 42, so long as the plate 42 is capable of pushing the second conductive member into conductive contact with the first conductive member 5 after the electrical contact 201 is inserted into the compression chamber 41. The specific movement modes of the plate body 42 and the second conductive member 6 are not limited in this application.

As an alternative embodiment, for example, as shown in fig. 2 to 8, the second conductive element 6 of the present application is rotatably disposed in the accommodation chamber 3.

Further, as shown in fig. 2 to 5, the plug bush assembly 4 of the present application may further include a threaded fastener 43 configured as a conductor, where the threaded fastener 43 includes a head 431 and a screw portion 432 coaxially connected, the head 431 is disposed in the extrusion cavity 41, the plate 42 is provided with a first mounting hole 421 through which the screw portion 432 penetrates, and the screw portion 432 is used for electrically contacting with the second conductive member 6.

Thus, in one aspect, the threaded fastener 43 may serve as a mounting structure for the ferrule assembly 4 such that the plate 42 can be securely mounted within the receiving cavity 3; on the other hand, the threaded fastener 43 may act as an electrical connector such that the electrical contact 201, after insertion into the extrusion cavity 41, is capable of being brought into electrical connection with the second conductive member 6 by the threaded fastener 43.

Also, it is understood that the dimensional relationship of the head 431 and the shank 432 of the threaded fastener 43 has various embodiments, for example, the radial dimension of the head 431 may be greater than the radial dimension of the shank 432 so that the threaded fastener 43 can reliably mount the ferrule assembly 4 within the receiving cavity 3. The radial dimension of the head 431 may be smaller than or equal to the radial dimension of the screw portion 432, so that the mounting and fixing of the plug bush assembly 4 can be achieved.

In addition, the plug bush assembly 4 of the present application may be fixed in the accommodating chamber 3 by other mounting methods, for example, a mounting method such as a snap-in, a plug-in, or an adhesive.

In an exemplary embodiment of the present application, as shown in fig. 2, 3 and 6, the second conductive member 6 of the present application includes a butt portion 61 and a mounting portion 62 which are connected to each other and configured in an L-shape, the butt portion 61 is disposed opposite to the first conductive member 5, and the mounting portion 62 is provided with a second mounting hole 621 through which the screw portion 432 is inserted. In this way, the abutting portion 61 of the second conductive member 6 can make conductive contact with the first conductive member 5; the mounting portion 62 may enable the second conductive member 6 to be reliably mounted in the accommodating chamber 3 on the one hand, and the mounting portion 62 may also enable the second conductive member 6 to form a reliable electrical connection path with the threaded fastener 43 on the other hand.

In an exemplary embodiment of the present application, as shown in fig. 2, 3, 7 and 8, the socket 100 of the present application may further include a transmission member 7 disposed in the receiving cavity 3, the transmission member 7 including a rod body 71, one end of the rod body 71 abutting against the plate 42, the other end of the rod body 71 extending toward the direction of the second conductive member 6 and having a distance from the second conductive member 6, and the rod body 71 being configured to be capable of pushing the second conductive member 6 into conductive contact with the first conductive member 5 when the electrical contact 201 is inserted into the pressing cavity 41.

Thus, after the electric contact 201 is inserted into the pressing cavity 41, the plate 42 can push the transmission member 7 to move towards the second conductive member 6, so that the transmission member 7 can push the second conductive member 6 to be in conductive contact with the first conductive member 5.

In an exemplary embodiment of the present application, as shown in fig. 2, 3, 7 and 8, the transmission member 7 of the present application may further include an elastic restoring member 72 configured as a tubular structure, the elastic restoring member 72 including a first end 721 and a second end 722, the first end 721 being sleeved on the rod main body 71, the second end 722 being mounted between the second conductive member 6 and the plate body 42; and/or, the housing 2 is provided with a first mounting cavity 21, the transmission member 7 is movably arranged in the first mounting cavity 21, the first end 721 is positioned in the first mounting cavity 21, and the radial dimension of the second end 722 is larger than that of the first mounting cavity 21.

Thus, in one aspect, when the plug is pulled out (i.e., the electrical contact 201 is pulled out from the pressing cavity 41), the elastic restoring member 72 can rebound the transmission member 7 to the original position, so that the next plugging operation of the plug and the socket 100 can be smoothly performed. Meanwhile, since the elastic restoring member 72 is configured to have a tubular structure, the elastic restoring member 72 is beneficial to applying a restoring force which is distributed along the axial direction of the transmission member 7 and is relatively balanced to the transmission member 7, so that the transmission member 7 can be stably and reliably restored to the original position. In addition, the radial dimension of the first end 721 is smaller than the radial dimension of the second end 722, which can be advantageous to ensure that the direction of the restoring force can be more toward the axial direction of the transmission member 7, so that the transmission member 7 can be more stably and reliably returned to its original position.

On the other hand, since the first end 721 of the elastic restoring member 72 is located in the first mounting cavity 21 and the radial dimension of the second end 722 is greater than that of the first mounting cavity 21, the elastic restoring member 72 of the present application can also play a certain sealing role, so that the movement state of the transmission member 7 does not affect the tightness of the space where the electrical contact 201 is located, which is beneficial to improving the sealing effect of the socket 100.

It will be appreciated that in this embodiment, the elastic restoring member 72 may be made of a material having elasticity and sealing capability, such as silicone, rubber, or plastic; the transmission member 7 may be any material having a certain structural strength, such as plastic, rubber, metal, ceramic, glass, etc., and the specific materials of the elastic restoring member 72 and the transmission member 7 are not limited in this application.

In addition, as shown in fig. 1, for easy installation, a mounting bracket 91 and a sleeve sealing pressing plate 83 may be further disposed in the housing 2, and the mounting bracket 91 and the sleeve sealing pressing plate 83 may be used as mounting bodies of the structures such as the sleeve assembly 4, the first conductive member 5, the second conductive member 6, and the transmission member 7. The ferrule assembly 4 may be mounted within the housing 2 by a ferrule sealing silicone 82 and a ferrule nut 81. In addition, in order to facilitate the reliable installation of the transmission member 7, the present application may further provide a pressing cover 92 between the mounting bracket 91 and the second conductive member 6, the pressing cover 92 may be provided with a through hole for the rod body 71 to pass through, and the pressing cover 92 may serve as a mounting structure of the elastic restoring member 72 and the transmission member 7, and define the positions of the elastic restoring member 72 and the transmission member 7 together with the mounting bracket 91.

Meanwhile, the sealing manner (or mounting manner) between the transmission member 7, the elastic restoring member 72 and the pressing cover 92 of the present application may be selected in the form of bonding, vulcanization, screw connection, double-shot molding, or the like, which is not particularly limited in this application. The sealing manner between the threaded fastener 43 and the sleeve sealing pressure plate 83 of the present application may be selected in the form of a threaded structure seal, or may be selected in the form of an interference fit, a glue seal, or the like, which is not particularly limited in this application.

As an alternative, as shown in the figure, the second conductive element 6 of the present application is movably arranged in the housing chamber 3.

Further, as shown in fig. 9 to 13, the plate 42 and the second conductive member 6 of the present application are both configured as conductors, the second conductive member 6 includes a conductive rod 63, one end of the conductive rod 63 abuts against the plate 42, the other end of the conductive rod 63 extends toward the direction of the first conductive member 5 and is spaced from the first conductive member 5, and the conductive rod 63 is configured to be capable of being pushed into conductive contact with the first conductive member 5 when the electric contact 201 is inserted into the pressing cavity 41.

As such, in this embodiment, the second conductive member 6 of the present disclosure may directly form an electrical connection relationship with the board 42, on the one hand, the structure of the socket 100 of the present application can be effectively simplified, and on the other hand, the second conductive member 6 directly forms an electrical connection relationship with the board 42, so that the reliability of the electrical connection relationship of the socket 100 can be higher.

It should be understood that, when the electrical contact 201 is inserted into the extrusion cavity 41, the conductive rod 63 and the plate 42 may have various matching forms, for example, in one embodiment, as shown in fig. 10, when the electrical contact 201 is inserted into the extrusion cavity 41, the electrical contact 201 pushes a portion of the plate 42 to rotate, so as to drive the conductive rod 63 to move, so that the conductive rod 63 can be in conductive contact with the first conductive member 5; in another embodiment, as shown in fig. 11, the electrical contact 201 may directly push the conductive rod 63 to move during the insertion into the extrusion cavity 41, so that the conductive rod 63 can be in conductive contact with the first conductive member 5.

In an exemplary embodiment of the present application, as shown in fig. 9 to 13, the second conductive member 6 of the present application may further include an elastic restoring structure 64 configured in a tubular shape, the elastic restoring structure 64 including a third end 641 and a fourth end 642, the third end 641 being sleeved on the conductive rod 63, the fourth end 642 being installed in the receiving chamber 3; and/or, a second mounting cavity 22 is provided in the housing 2, the conductive rod 63 is movably disposed in the second mounting cavity 22, the third end 641 is located in the second mounting cavity 22, and the radial dimension of the fourth end 642 is greater than the radial dimension of the second mounting cavity 22.

Thus, in one aspect, when the plug is pulled out (i.e., the electrical contact 201 is pulled out of the pressing cavity 41), the elastic return structure 64 can rebound the conductive rod 63 to the original position, so that the next plugging operation of the plug and the socket 100 can be performed smoothly. Meanwhile, since the elastic restoring structure 64 is configured as a tubular structure, the elastic restoring structure 64 is beneficial to applying a relatively balanced restoring force to the conductive rod 63 along the axial direction of the conductive rod 63, so that the conductive rod 63 can be stably and reliably restored to the original position. In addition, the radial dimension of the third end 641 is smaller than the radial dimension of the fourth end 642, which can be advantageous in ensuring that the direction of the restoring force can be more toward the axial direction of the conductive rod 63, so that the conductive rod 63 can be more stably and reliably returned to its original position.

On the other hand, since the third end 641 of the elastic restoring structure 64 is located in the second mounting cavity 22 and the radial dimension of the fourth end 642 is larger than the radial dimension of the second mounting cavity 22, the elastic restoring structure 64 of the present application can also play a role in sealing to a certain extent, so that the movement state of the conductive rod 63 does not affect the tightness of the space where the electrical contact 201 is located, which is beneficial to improving the sealing effect of the socket 100.

It should be understood that in this embodiment, the elastic restoring structure 64 may be made of a material with elastic and sealing capabilities, such as silicone, rubber, and plastic, and the specific material of the elastic restoring structure 64 is not limited in this application.

In addition, the elastic reset structure 64 of the present application can cooperate with the gland 92 in the above embodiment to seal the socket 100 together, so that the movement state of the conductive rod 63 does not affect the tightness of the space where the electrical contact 201 is located, thereby further improving the sealing effect of the socket 100.

In an exemplary embodiment of the present application, as shown in fig. 4 and 5, the plate body 42 of the present application may be formed in a U-shaped structure, the plate body 42 including a first portion 422 and a second portion 423 disposed opposite to each other, and a third portion 424 connected between the first portion 422 and the second portion 423, and the compression chamber 41 is formed between the first portion 422, the second portion 423, and the third portion 424; wherein the first portion 422 is bent at least once to form an elastic structure.

Thus, in one aspect, the plate 42 can directly form the extrusion cavity 41, so as to facilitate the insertion of the power contact 201, which is beneficial to ensuring that the power contact 201 can reliably push the plate 42, and further enable the plate 42 to push the second conductive member 6 into conductive contact with the first conductive member 5; on the other hand, the first portion 422 is formed in an elastic structure, not only enabling the plate body 42 to reliably hold the electrical contact 201, but also enabling the first portion 422 of the plate body 42 to automatically return to its original position after the electrical contact 201 is pulled out of the pressing chamber 41.

Furthermore, it will be understood that, first, as shown in fig. 1 and 9, for a five-hole socket (i.e., a two-hole plug and a three-hole plug are commonly provided on one socket), the first conductive members 5 corresponding to the two-hole plug and the three-hole plug may be constructed as an integral structure, so that not only the mounting structure of the first conductive members 5 can be reduced to simplify the structure of the socket, but also the number and volume of the first conductive members 5 can be reduced to save manufacturing cost. Second, as shown in fig. 14 and 15, various connection modes, for example, a direct conduction mode (refer to fig. 14), that is, a common connection mode, may be adopted; or in the form of cross-over power (see fig. 15), i.e. when the live wire is plugged in, the line corresponding to the neutral wire is conducted, and when the neutral wire is plugged in, the line corresponding to the live wire is conducted. Thus, the safety of the socket is further improved.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art.
