For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0034] The new track plate 1 and track-type socket proposed in this embodiment can prevent dust and other impurities from entering the interior of the track plate 1 through the installation port 101 of the adapter 2 on the track plate 1 when the adapter 2 is not installed on the track plate 1, further play a protective role for the track plate 1, and improve the service life of the track plate 1 and the track-type socket.

[0035] like Figure 1 As shown, the track socket is composed of a track plate 1 and a plurality of adapters 2 arranged on the track plate 1. The track plate 1 can be arranged on a wall or embedded in a table. Figure 1 The track plate 1 shown has three mounting openings 101 , on which three adapters 2 can be mounted for use.

[0036] Continue to refer to Figure 1 A conductive pin 21 is disposed on each side of the base of the adapter 2, and the two conductive pins 21 are staggered in the length direction of the base. A grounding pin 22 extends from the bottom of the adapter 2.

[0037] Combination Figure 2 The track plate 1 is provided with three conductive strips 16 in its shell plate, which correspond to the N pole (indicating the neutral line or zero line), the L pole (indicating the phase line or live line) and the E pole (indicating the ground line), and each conductive strip 16 is provided with three conductive sleeves 161, which correspond to the three mounting ports 101 respectively. The three conductive pins 21 on an adapter 21 will be respectively plugged into the conductive sleeves 161 on the three conductive strips 16 for conduction.

[0038] The track plate 1 is provided with at least one adapter 2 mounted thereon to form a track-type socket. The top of the shell plate of the track plate 1 is provided with a plurality of mounting openings 101 for the adapter 2. Figure 2 and Figure 3 It can be seen that two safety doors 11 and two elastic members 12 are provided at each installation opening 101. The two safety doors 11 are arranged in parallel along the length direction of one installation opening 101, and the two safety doors 11 are respectively hinged at opposite sides of the installation opening 101, and the safety doors 11 are also provided with a stopper 111 that can be stuck on the inner edge of the installation opening 101. Correspondingly, an elastic member 12 is provided between the hinged side of one safety door 11 and the inner side of the installation opening 101, and the elastic member 12 is configured to restore the safety door 11 to the point where the stopper 111 is close to the inner side of the installation opening 101 by its elastic force.

[0039] By such arrangement, when the base of the adapter 2 is inserted into the mounting opening 101 on the track plate 1, the safety door 11 overcomes the elastic force of the elastic member 12 and rotates to its lowered position, and the adapter 2 as a whole covers the mounting opening 101 on the track plate 1. When the adapter 2 is removed from the track plate 1, the safety door 11 rotates under the elastic restoring force of the elastic member 12 until the stopper 111 is close to the inner side of the mounting opening 101, so as to prevent dust and other impurities in the external environment from entering the interior of the track plate 1, further protecting the track plate 1 and improving the service life of the track plate 1 and the track-type socket.

[0040] In a preferred embodiment of the track plate 1 and the track socket, refer to Figure 4 Two connecting claws 112 are provided on the same side of the safety door 11, and a hinge slot portion 1121 is provided on the connecting claw 112. Two rotating shaft portions 131 are provided on the shell plate corresponding to one safety door 11, and the safety door 11 is hinged at the installation port 101 of the shell plate through the rotational cooperation between the rotating shaft portion 131 and the hinge slot portion 1121. In this embodiment, the rotation directions of the two safety doors at the same installation port 101 are opposite. In addition, this structure can facilitate the installation, disassembly and replacement of the safety door 11. In addition, by adopting that the two ends of the safety door 11 are respectively hinged to different rotating shaft portions 131, the influence of the hinged installation of the safety door 11 on other functions of the shell plate can be reduced.

[0041] In a preferred embodiment of the track plate 1 and the track socket, Figure 3 and Figure 4The elastic member 12 on the track plate 1 is a torsion spring, which is coaxially sleeved on a rotating shaft portion 131, and a connecting rod 121 at one end of the torsion spring is fixed on the shell plate, for example, can be inserted into the track plate 1. The connecting rod 121 at the other end of the torsion spring abuts against the inner side of the connecting claw 112. In this way, the function of moving and restoring the safety door 11 can be easily achieved through the torsion spring. In addition, the elastic member 12 can also be selected as other types, such as tension springs, coil springs, leaf springs, bellows, etc., and corresponding settings for different types of elastic members 12 can achieve the function of the elastic member 12 of the utility model to restore the safety door 11 to the inner side of the stopper 111 close to the installation port 101 by its elastic force.

[0042] In a preferred embodiment of the track plate 1 and the track socket, refer to Figure 5 The shell of the track plate 1 is also provided with a mounting seat 132 at the lower end of the mounting opening 101. Each of the two opposite sides of the mounting seat 132 is provided with a window 1321 and a avoidance opening 1322. The window 1321 is for the conductive pin 21 of the adapter 2 to extend, and the avoidance opening 1322 is used to accommodate a lowered safety door 11. In addition, a through hole 1323 is provided at the bottom of the mounting seat 132, and the through hole 1323 is for the grounding pin 22 of the adapter 2 to pass through. In this way, when the base of the adapter 2 extends from the mounting opening 101 of the track plate 1 into the mounting seat 132, the safety door 11 can be rotated downward to the avoidance opening 1322, and by operating the adapter 2, its conductive pin 21 can extend from the window 1321 on the mounting seat 132 and plug and conduct electricity with the conductive sleeve 161 on the conductive strip 16.

[0043] In a preferred embodiment of the track plate 1 and the track socket, continue to refer to Figure 2 The shell plate of the track plate 1 includes a cover plate 13 and a bottom plate 14. The safety door 11 is hinged on the cover plate 13, and a groove 133 is formed on the inner side of the top wall of the cover plate 13 to cooperate with the stopper 111, and a mounting seat 132 is arranged on the cover plate 13. A first peripheral wall 141 surrounding the cover plate 13 is formed on the top periphery of the bottom plate 14, so that the cover plate 13 can be arranged therein. For example, the bottom plate 14 and the cover plate 13 can be connected together by a plurality of screws.

[0044] In a preferred embodiment of the track plate 1 and the track socket, continue to refer to Figure 2 The shell plate of the track plate 1 further includes a cover plate 15, and the bottom periphery of the cover plate 15 is formed with a second peripheral wall 152 surrounding the bottom plate 14, so as to cover the cover plate 13 on the bottom plate 14. For example, a plurality of slots are arranged on the outer side of the first peripheral wall 141 of the bottom plate 14, referring to Figure 3The inner side of the second peripheral wall 152 of the cover plate 15 may be provided with a plurality of buckles 1521, so that the cover plate 15 and the bottom plate 14 are engaged with each other through the buckles 1521 and the slots. In this way, the cover plate 15 covers the cover plate 13 inside, thereby preventing dust from entering the gap between the bottom plate 14 and the cover plate 13, and further achieving a closer contact with the safety door 11, thereby achieving a better dust blocking effect.

[0045] In addition to the above-described installation method of the safety door 11 at the installation opening 101 on the track plate 1, two ends of the safety doors 11 that are away from each other can also be hinged at the installation opening 101. For example, Figure 2 The middle safety door 11 is in the shape of a long strip, and the short side of the safety door 11 can be hinged to the installation opening 101. Figure 4 The illustrated embodiments in which the long side of the safety door 11 is hinged to the installation opening 101 are different implementations, and both can achieve the purpose of hingedly connecting the safety door 11 to the installation opening 101 of the track plate 1 .

[0046] The present application relates to the technical field of low-voltage electrical equipment, and in particular to a track plate 1 and a track-type socket. The top of the shell plate of the track plate 1 is provided with a plurality of mounting openings 101 for adapters 2, and two safety doors 11 and two elastic members 12 are provided at each mounting opening 101. When the base of the adapter 2 is inserted into the mounting opening 101 on the track plate 1, the safety door 11 overcomes the elastic force of the elastic member 12 and rotates to its lowered position, and the adapter 2 as a whole covers the mounting opening 101 on the track plate 1. When the adapter 2 is removed from the track plate 1, the safety door 11 rotates to the inner side of the stopper 111 close to the mounting opening 101 under the action of the elastic restoring force of the elastic member 12, so as to prevent dust and other impurities in the external environment from entering the interior of the track plate 1, further playing a protective role for the track plate 1, and improving the service life of the track plate 1 and the track-type socket.
