As shown in fig. 2, there is disclosed a safety door assembly 100 for a socket according to the present disclosure, the safety door assembly 100 including a safety door base 3, and a safety door slider 1 and an elastic member 2 built into the safety door base 3. The safety door base 3 is provided with a plurality of jacks corresponding to the socket hole shapes, and the jacks can be arranged as I-shaped jacks and/or T-shaped jacks according to actual needs, such as the I-shaped jacks 33 and the T-shaped jacks 34 exemplarily shown in the figure, so that the safety door base can be suitable for sockets of different standards. The safety door base 3 is further provided with a limiting member 35 and a balancing member 31 which can be abutted against the safety door slider 1. As shown in fig. 1A to 1C, the safety door slider 1 includes: a slider base 11, a first slider protection door 111, a second slider protection door 112, and at least one protection door reinforcement 12. According to the present application, the stopper 35 can restrict the movement of the safety door slider 1 when the insert is inserted against only one of the first and second slider protection doors 111 and 112; when the insert is simultaneously inserted against the first and second slider protection doors 111 and 112, the safety door slider 1 can move along the safety door base 3 by the counterbalance 31 to expose the socket hole. Preferably, the elastic member 2 is provided to enable the safety door slider 1 to cover the socket hole in its initial state. In this way, the safety door assembly can effectively prevent the insertion of foreign substances or the erroneous operation of the plug, and simultaneously, when in a protection state (i.e., the safety door slider 1 covers the socket hole), the safety door assembly 100 can also isolate the components in the socket from the outside, thereby preventing the adverse effects of external environments (e.g., dust, moisture, etc.).
In the present embodiment, the protective door reinforcement 12 may be provided in the first slider protective door 111 or the second slider protective door 112, or the corresponding protective door reinforcement 12 may be provided in the first slider protective door 111 and the second slider protective door 112, respectively. In addition, by providing the processing groove 121 on the first slider protective door 111 and/or the second slider protective door 112, the protective door reinforcement 12 is fixed to the first slider protective door 111 and/or the second slider protective door 112 via the processing groove while the first slider protective door 111 and/or the second slider protective door 112 is thermoplastically processed (for example, injection molding technique), so that the protective door reinforcement 12 is integrally formed with the first slider protective door 111 and/or the second slider protective door 112.
In the example shown in fig. 1A to 1C, the protective door reinforcement 12 is provided only in the first slider protective door 111. In practical applications, the protective door reinforcement 12 may be disposed in the first slider protective door 111 and/or the second slider protective door 112 as needed. The protective door reinforcement is made of a metal material or a hard wear-resistant material.
In this embodiment, a protective door reinforcement covers a portion of the first or second slider protective door that contacts the insert.
In some embodiments, the balancing member is provided as a lever shaft (fig. 2, 3B and 4B) with an arc-shaped surface protruding from the inner surface of the bottom of the safety door base 3, the lever shaft extending perpendicular to the moving direction of the safety door slider 1, and preferably, the balancing member 31 is located at a substantially middle position of the bottom surface of the safety door slider 1 in the initial state of the elastic member 2. Therefore, the balance effect of the slide block on the overturning of the safety door base and the movement along the safety door base is obtained through the bar shaft, the friction is reduced, and the service life is prolonged. It will be appreciated that the lever shaft may also be provided as a rib, or as a plurality of successive projections extending perpendicular to the direction of movement of the slider, or even directly as one larger projection.
In some embodiments, the balancing member may include a pair of lever shafts symmetrically disposed at the bottom inner surface of the safety door base 3, the pair of lever shafts being disposed to extend toward each other perpendicular to the moving direction of the safety door slider 1.
As can also be seen from fig. 3B and 4B, the limiting member 35 on the safety door base 3 includes a projection protruding from the inner surface of the bottom of the safety door base 3, and similarly, the projection may be configured as a rib or a bump. Advantageously, the projection is arranged adjacent to at least one receptacle. As shown in fig. 1B, the safety door slider 1 is provided with a bottom surface a corresponding to the inner surface of the bottom of the safety door base 3, and the bottom surface a is substantially parallel to the inner surface of the bottom of the safety door base 3. The safety door slider 1 is provided with a first stopper surface B that can abut against the projection. In order to limit the sliding block, a further limiting projection 41 can also be provided on the receptacle, and advantageously the limiting projection 41 is arranged adjacent to at least one receptacle opening, as shown in fig. 5B and 6A, and correspondingly a second limiting surface C is also provided on the safety door sliding block 1 for abutment with the limiting projection 41, as will be described in detail below.
Referring to fig. 1A, 2, and 3A to 4B, according to the present application, the elastic member 2 may be any one of a compression spring, a tension spring, a spring plate, or a torsion spring, which is exemplarily illustrated as a torsion spring. One end of the elastic piece 2 is connected with the safety door sliding block 1, and the other end of the elastic piece abuts against a corresponding structure arranged on the safety door base 3, for example, the inner side wall of the safety door base 3. The safety door base 3 is provided with an elastic member fixing part 32 for fixing the elastic member 2, and the elastic member fixing part 32 includes a projection or a hole groove protruding from the inner surface of the bottom or the inner surface of the sidewall of the safety door base 3. In order to simplify the structure and reduce the accommodation space in the socket, the safety door slider 1 is provided with an elastic piece receiving groove 132 for accommodating the elastic piece 2, and the elastic piece receiving groove 132 can also realize the installation and positioning of the safety door slider 1 and the elastic piece 2. In some embodiments, the elastic member receiving groove 132 may be provided therein with a working surface 131 for driving the elastic member 2 to be elastically deformed, and a restricting surface 132 for maintaining the elastic member 2 in an elastically deformed state. Specifically, referring to fig. 3A and 3B, when the elastic member 2 is in an initial state, that is, the safety door slider 1 covers the insertion hole (and thus the receptacle hole), if normal insertion of the insertion member is performed, one end of the elastic member 2 abutting against the safety door slider 1 is elastically deformed along with the movement of the safety door slider 1 and moves along the working surface 131 until moving to the restriction surface 132, at which time the insertion hole (and the receptacle hole) is exposed, and the insertion member can be smoothly inserted, as shown in fig. 4A and 4B.
Furthermore, as can also be seen in the figures, in some embodiments, the two slide protection doors of the safety door slide may be provided with different ramp sizes to allow for different travel strokes of the insert. For example, the first slider protective door 111 fits into the I-shaped receptacle 33 and the second slider protective door 112 has a larger bevel size to fit into the T-shaped receptacle 34, which helps to adapt the security door assembly to different standard sized receptacles, such as the ANSI/NEMA WD6 standard.
The operation of the safety door assembly of the present application is further described below in conjunction with fig. 5A-6B.
First, the socket is shown as including a housing including an upper cover 4 and a base 6 connected to each other, and socket blades 51, 52 disposed within the housing, the above-described safety door assembly being provided between the upper cover 4 and the socket blades 51, 52.
When no insert is inserted, the safety door assembly keeps the safety door slider 1 in a static state without overturning or inclining relative to the safety door base due to the action of the elastic member 2, and the safety door assembly is in a closed state.
When a foreign object is inserted from one socket hole of the socket, as shown in fig. 5A, into the left socket hole, the foreign object contacts the second slider protection door 112 on the safety door slider 1 and moves downward to apply a downward force, the right side of the safety door slider 1 is raised due to the balance member 31, and the left side is limited by the first limiting surface B and the limiting member 35 on the safety door base 3, so that the foreign object cannot be inserted. Similarly, when a foreign object is inserted from the socket hole on the right side as shown in fig. 5B, the first slider protection door 111 on the right side of the safety door slider 1 is applied with a downward force, so that the left side of the safety door slider 1 is raised, and at this time, the second limit surface C of the safety door slider 1 abuts against the limit protrusion 41 on the socket housing. Foreign matters can not be inserted, and safety protection is realized.
As described above, the security door assembly of the present application is suitable for use in a variety of receptacles under the ANSI/NEMA WD6 standard, such as 1-15P, 5-20P, 6-15P, 6-20P, and the like. When a plug conforming to the standard is used for insertion, such as the NEMA 15A plug shown in fig. 6A and 6B, the plug members are simultaneously inserted into the two receptacle holes of the upper cover 4, and the safety door slider 1 is not turned over with respect to the safety door base 3 due to the balancing action of the balancing members 31. At this time, due to the downward insertion force along the first and second slider protection gates of the safety door slider 1, the safety door slider 1 moves along the safety door base 3 and compresses the elastic member 2, thereby exposing the socket hole, and the plug can be normally inserted and electrically connected by contacting with the socket pieces 51 and 52. It will be appreciated that if the plug is pulled out, the safety door slider 1 will move back to the original position due to the resilience of the elastic member 2, and continue to protect against misinsertion.
Figure 7 illustrates a receptacle structure for use with the safety door assembly of the present application, wherein figure 7 includes two safety door assemblies 100 similar to the receptacle shown in figures 6A-6B. The safety door assembly has a wide range of applications because the safety door assembly has a compact and simple structure and the overall size of the receptacle in which the safety door assembly is installed does not vary much. Furthermore, because the safety door assembly of the present disclosure has few components and the components can be limited from each other, the safety door assembly can be automatically manufactured and assembled into a whole.
It should be understood that the embodiments shown in fig. 1-7 illustrate only alternative shapes, sizes and arrangements of various optional components of the safety door assembly and receptacle according to the present disclosure, however, they are merely illustrative and not limiting and that other shapes, sizes and arrangements may be adopted without departing from the spirit and scope of the present application. In addition, the safety door base and the safety door slider of the safety door assembly in the above embodiment are respectively shown and described as being integrally formed, thereby facilitating the processing and assembly, but may be formed separately or partially in combination according to the number of the receptacle holes.
Thus, while the present invention has been described with reference to specific examples, which are intended to be illustrative only and not to be limiting of the invention, it will be apparent to those of ordinary skill in the art that changes, additions or deletions may be made to the disclosed embodiments without departing from the spirit and scope of the invention.
