[0029] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] In the description of the present invention, it should be understood that descriptions involving orientation, such as up, down, front, back, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] In the description of the present invention, if there is a description of first, second, etc., it is only for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] like Figure 1 As shown, a power distribution device according to an embodiment of the present invention includes a power rail and a tap.

[0034] Among them, refer to Figures 2 to 4The power rail includes a first housing 100, a rubber strip 210, an insulating spacer 300, a conductive strip group 400, an end cap 220 and a terminal block 230. The first housing 100 is provided with a first socket 110, and two rubber strips 210 are provided. The two rubber strips 210 are arranged in parallel, and the two rubber strips 210 are both provided at the first socket 110. The first socket 110 is shielded by the two rubber strips 210, that is, at least a part of the longitudinal projection of each of the two rubber strips 210 is located within the longitudinal projection of the first socket 110. The end caps 220 are provided at the front and rear ends of the first housing 100.

[0035] Reference Figure 5 The splitter has an insertion portion 610, and the front and rear sides of the insertion portion 610 both have transition portions 620, and each transition portion 620 gradually reduces in width along the direction toward the corresponding end face, that is, the transition portion 620 on the front side gradually reduces in width toward the front, and the transition portion 620 on the rear side gradually reduces in width toward the rear.

[0036] During installation, the insertion part 610 is inserted into the first socket 110, and the insertion part 610 can slide back and forth along the first socket 110. The insertion part 610 squeezes the rubber strip 210, and the two rubber strips 210 jointly clamp the transition part 620. Since the width of the transition part 620 gradually decreases along the direction toward the corresponding end face, the gap between the rubber strip 210 and the end face of the transition part 620 is very small, which can effectively block the entry of foreign matter, avoid foreign matter entering the first shell 100 and causing electrical accidents, and improve safety. In addition, since the width of the transition portion 620 gradually decreases in the direction toward the corresponding end face, the deformation of the rubber strip 210 near the insertion portion 610 is relatively gentle, which can prevent the rubber strip 210 corresponding to the middle part of the side wall of the insertion portion 610 from warping up, so that the rubber strip 210 can better fit the insertion portion 610 to stably clamp the insertion portion 610. When the insertion portion 610 is inserted into the first socket 110, the stable clamping of the rubber strip 210 can prevent the insertion portion 610 from slipping out of the first socket 110.

[0037] Reference Figure 5 The two side walls of the transition portion 620 are connected through their respective corresponding end faces. In some embodiments, the two side walls of the transition portion 620 can be directly connected to form a wedge-shaped cross section of the transition portion 620.

[0038] It is understandable that the side wall of the transition portion 620 may be in the shape of an inclined plane or in the shape of a curved surface.

[0039] Reference Figure 2 and Figure 3 The rubber strip 210 is provided with a first clamping protrusion 211 , and the first shell 100 is provided with a first clamping slot 120 . The first clamping protrusion 211 is disposed in the first clamping slot 120 to connect the rubber strip 210 with the first shell 100 .

[0040] It is understandable that in some embodiments, the first protrusion 211 may be disposed on the first housing 100, and the first slot 120 may be disposed on the rubber strip 210. Alternatively, the rubber strip 210 may be bonded to the first housing 100, or the rubber strip 210 may be fixed to the first housing 100 by means of screws, a pressure plate, or a buckle.

[0041] In addition, the length of the inserting portion 610 is smaller than the length of the tap, and the width of the inserting portion 610 is also smaller than the width of the tap. The tap can shield the joint between the inserting portion 610 and the rubber strip 210 to prevent foreign matter from entering through the joint.

[0042] Reference Figure 2 and Figure 3 The insulating isolation member 300 includes a first isolation portion 310 and a second isolation portion 320. The first isolation portion 310 includes two isolation layers 311. The two isolation layers 311 are arranged in sequence from the inside to the outside, and there is a distance between the two isolation layers 311, that is, an air barrier is formed between the two isolation layers 311, and the innermost isolation layer 311 is surrounded to form a mounting cavity 330. The conductive strip group 400 includes a power supply strip 410 and a grounding strip 420. The power supply strip 410 is arranged in the mounting cavity 330, and the grounding strip 420 is arranged on the second isolation portion 320. The power supply strip 410 is used to connect the live / neutral wire to transmit electricity, and the grounding strip 420 is used to connect the ground wire. The end cover 220 is arranged at the end of the first shell 100 to shield the end surface of the first shell 100.

[0043] As described above, the first isolating portion 310 is configured as a hollow double-layer structure, which can have a good insulation isolation effect, reduce the probability of current leakage to the first shell 100, thereby reducing the risk of electric shock and improving safety. In addition, there is no need to excessively increase the total material thickness of the first isolating portion 310, which can reduce the material cost of the first isolating portion 310.

[0044] It is understood that in some embodiments, the number of isolation layers 311 in the first isolation portion 310 may be set to more than three, and the three or more isolation layers 311 are arranged in sequence from the inside to the outside, and there is also a gap between adjacent isolation layers 311. In this way, the first isolation portion 310 can be set to a structure of more than three layers to optimize the insulation isolation effect.

[0045] Ribs 360 are connected between adjacent isolation layers 311. Ribs 360 are used to support and increase the strength of the first isolation part 310 to prevent deformation.

[0046] Reference Figure 2The second isolation part 320 is arranged below the first socket 110, and the first isolation part 310 is provided with two, and the two first isolation parts 310 are respectively arranged on both sides of the second isolation part 320, and each first isolation part 310 is provided with a power supply bar 410, that is, the power supply bar 410 is provided with two, and the two power supply bars 410 are respectively arranged on both sides of the grounding bar 420. Such a structure is relatively symmetrical and can be evenly stressed. One of the power supply bars 410 is used to connect the live wire, and the other power supply bar 410 is used to connect the neutral wire.

[0047] The first isolating portion 310 and the second isolating portion 320 are configured as an integral structure, and the insulating isolating member 300 can be integrally formed by extrusion to simplify its processing and reduce assembly steps.

[0048] The insulating spacer 300 is clamped in the first housing 100 to position the insulating spacer 300. Specifically, a second clamping slot 130 is provided at a position of the first housing 100 close to the first socket 110, a second clamping protrusion 370 is provided at a corresponding position of the insulating spacer 300, and the second clamping protrusion 370 is provided in the second clamping slot 130. A third clamping protrusion 140 is provided at the bottom of the first housing 100, a third clamping slot 380 is provided at a corresponding position of the insulating spacer 300, and the third clamping protrusion 140 is provided in the third clamping slot 380.

[0049] In some embodiments, the second convex portion 370 may be disposed at a position of the first housing 100 close to the first socket 110, and the second slot 130 may be disposed at a corresponding position of the insulating spacer 300. Similarly, the third slot 380 may be disposed at the bottom of the first housing 100, and the third convex portion 140 may be disposed at a corresponding position on the insulating spacer 300.

[0050] Reference Figure 2 and Figure 3 The first isolation part 310 is provided with an isolation cavity 340 and a second socket 350, and the first socket 110, the isolation cavity 340, the second socket 350 and the installation cavity 330 are connected in sequence. The height of the second socket 350 is less than the height of the isolation cavity 340. The above structure can stably and reliably position the power supply bar 410. Here, Figure 3 The up and down direction shown in is the height direction.

[0051] Reference Figure 4 The terminal block 230 is provided at the end of the first housing 100, and the terminal block 230 has a power supply terminal 231 and a grounding spring 232. During assembly, the power supply terminal 231 contacts and cooperates with the power supply bar 410, and the grounding spring 232 is pressed on the grounding bar 420.

[0052] Reference Figures 5 to 9The splitter includes a second housing 500 , a connection base 600 , a plug-in component 710 and a conductive component 720 .

[0053] The plug assembly 710 is configured to be conductive, and is used to be plugged with a plug of an electrical appliance. The plug assembly 710 includes a live wire contact, a neutral wire contact, and a ground wire contact. The connection base 600 is rotatably connected to the second housing 500 so that the connection base 600 can rotate relative to the second housing 500. The aforementioned plug-in portion 610 is provided on the connection base 600. The plug assembly 710 is provided in the second housing 500. The conductive component 720 is provided on the second housing 500, and the conductive component 720 is electrically connected to the plug assembly 710.

[0054] During installation, the insertion portion 610 is inserted into the first socket 110, and then the second shell 500 is rotated, and the conductive component 720 rotates along with the second shell 500, so that the conductive component 720 contacts and cooperates with the conductive strip group 400, and the current on the power strip 410 can be transmitted to the plug-in component 710 through the conductive strip group 400 to power the electrical appliance.

[0055] The side wall of the insertion part 610 is concave to form a groove 611. When the insertion part 610 is inserted into the first socket 110, the insertion part 610 squeezes the rubber strip 210, and the two rubber strips 210 clamp the insertion part 610 together. A part of the rubber strip 210 elastically recovers to allow a part of it to extend into the groove 611. A bulge is formed between the groove 611 and the transition part 620. The rubber strip 210 can clamp the bulge. The rubber strip can form a large pressure on the side wall of the transition part 620, the side wall of the groove 611, and the side wall of the bulge to form a relatively stable multi-position clamping of the insertion part 610. In some cases, after using the electrical appliance, the user can turn the second shell 500 to disconnect the conductive component 720 from the power supply bar 410 to achieve power off. The insertion part 610 can be clamped relatively stably by the rubber strip 210 to prevent the insertion part 610 from slipping out of the first socket 110.

[0056] Reference Figure 6 and Figure 7 The splitter further includes a socket shell 730, which is disposed in the second housing 500, and the plug assembly 710 is disposed in the socket shell 730. In this way, the plug assembly 710 is also configured as a double-layer isolation structure, and both the second housing 500 and the socket shell 730 can insulate and isolate the plug assembly 710, thereby improving safety. The socket shell 730 includes an upper shell 731 and a bottom shell 732, which are buckled to facilitate installation of the plug assembly 710.

[0057] In some embodiments, the upper shell 731 and the bottom shell 732 may also be connected by bonding or screws.

[0058] Reference Figure 5 and Fig. 9 The conductive component 720 includes a conductive cylinder 721 , a grounding column 722 , an elastic member (not shown in the figure) and a conductive contact piece 723 .

[0059] The conductive cylinder 721 is arranged along the rotation axis of the connector 600, and the upper end of the conductive cylinder 721 is fixedly connected to the ground contact of the plug assembly 710, so that current can be transmitted between the conductive cylinder 721 and the plug assembly 710. The connector 600 rotates relative to the second housing 500 around the rotation axis.

[0060] The grounding post 722 is slidably inserted into the conductive tube 721, and the elastic member is arranged in the conductive tube 721. The elastic member is arranged above the grounding post 722, and the grounding post 722 can be pushed out of the lower end of the conductive tube 721 by the elastic member. Two conductive contacts 723 are provided, and the two conductive contacts 723 are arranged on both sides of the grounding post 722. The conductive contacts 723 are fixedly connected with the live wire contacts and the ground wire contacts of the plug assembly 710 to transmit current between the conductive contacts 723 and the plug assembly 710. The grounding post 722 contacts and the conductive tube 721 to transmit current; the elastic member can be a spring made of metal material, so that current can also be transmitted between the plug assembly 710 and the grounding post 722 through the elastic member.

[0061] The conductive tube 721 and the conductive contact piece 723 may be packaged in the second housing 500 , that is, during production, the conductive tube 721 and the conductive contact piece 723 are installed and positioned by insert injection molding.

[0062] During installation, the insertion portion 610 is inserted into the first socket 110, the grounding column 722 contacts and cooperates with the grounding strip 420, and the elastic member pushes the grounding column 722 so that the grounding column 722 can be closely attached to the grounding strip 420; then the second shell 500 is rotated, and the conductive contact piece 723 rotates accordingly, and the conductive contact piece 723 passes through the isolation cavity 340 and the second socket 350 in sequence, and finally enters the installation cavity 330 to contact and cooperate with the power supply strip 410. The isolation cavity 340 can facilitate the insertion of the conductive contact piece 723, and separate the power supply strip 410 from the first socket 110 by a distance, so as to prevent conductive foreign matter from directly entering the installation cavity 330 from the first socket 110, thereby improving safety. And the above structure can stably and reliably position the conductive contact piece 723.

[0063] It is understandable that the elastic member may also be made of other materials, such as a rubber strip 210 .

[0064] Reference Figure 6 and Figure 8, a first limiting groove 630 is provided on the connecting base 600, and a limiting member 540 is provided on the second housing 500. The first limiting groove 630 is arranged to deviate from the rotation axis of the connecting base 600, that is, there is a distance between the position of the first limiting groove 630 and the rotation axis of the connecting base 600. When the connecting base 600 rotates relative to the second housing 500 until the limiting member 540 is opposite to the first limiting groove 630, the limiting member 540 can move to be inserted into the first limiting groove 630.

[0065] For example, the limiting member 540 can be set as a screw, which is screwed on the second housing 500. When installing, the insertion part 610 is inserted into the first socket 110, and then the second housing 500 is rotated forward, and the connecting seat 600 rotates relative to the second housing 500. When the conductive contact piece 723 is rotated and inserted into the installation cavity 330, the first limiting groove 630 is opposite to the screw. The screw can be rotated to move the screw to insert into the first limiting groove 630, and the connecting seat 600 can be limited to rotate in the opposite direction relative to the second housing 500. Through this structure, it is possible to avoid the situation in which the second housing 500 is subjected to external force during use, resulting in the relative rotation of the second housing 500 and the connecting seat 600, and the conductive contact piece 723 can be kept in the state of being inserted into the installation cavity 330 and contacting and cooperating with the power supply bar 410, ensuring the stability and safety of current transmission; in some public places, it can also prevent someone from taking out the tap, ensuring that the tap can be kept on the power rail, and effectively protecting the property of the owner.

[0066] Of course, in some embodiments, the limiting member 540 can also be configured as a pin, a turn buckle, etc. Among them, the pin is inserted into the second housing 500; the turn buckle is pivoted on the second housing 500, that is, the turn buckle is inserted into the first limiting groove 630 by rotating.

[0067] It should be noted that the limiter 540 can be used as an optional structure. In a home environment, the limiter 540 does not need to be inserted into the first limiter slot 630, so that the user can turn off the power by rotating the second housing 500. In some public places, the limiter 540 can be inserted into the first limiter slot 630 to prevent the tap from falling off the power rail.

[0068] It is understandable that, in some embodiments, the limiting member 540 may be disposed on the connecting seat 600 , and the first limiting groove 630 may be disposed on the second shell 500 .

[0069] Reference Figure 6 and Figure 8The second housing 500 is provided with two arc-shaped through slots 521, which are arranged around the rotation axis of the connecting seat 600. A mounting portion 640 is provided on the connecting seat 600 in one-to-one correspondence with each through slot 521, and the mounting portion 640 is penetrated through the through slot 521, wherein a second limiting slot 641 is provided on the side wall of the mounting portion 640, and a part of the second housing 500 extends into the second limiting slot 641, so that the connecting seat 600 and the second housing 500 can be rotatably connected, and the connecting seat 600 can be restricted from being separated from the second housing 500. The second limiting slot 641 is formed by the top surface of the connecting seat 600 and the mounting portion 640.

[0070] In some embodiments, the second limiting groove 641 may also be spaced apart from the top surface of the connecting base 600 by a certain distance, that is, the second limiting groove 641 is only provided on the mounting portion 640 .

[0071] It is understandable that a limiting protrusion may be provided on the side wall of the mounting portion 640 , and a third limiting groove may be provided on the second shell 500 , and the limiting protrusion and the third limiting groove may be inserted and matched.

[0072] In some embodiments, the number of through slots 521 may be more than three. Two or more through slots 521 may be arranged on the same circle or on multiple concentric circles. The rotation axis of the connection seat 600 passes through the centers of these circles.

[0073] In some embodiments, a pressure plate can be provided, and the pressure plate and the connecting seat 600 are connected by fastening screws, and the fastening screws are passed through the through groove 521. The pressure plate and the connecting seat 600 jointly clamp the second shell 500, so that the connecting seat 600 and the second shell 500 can be rotatably connected, and the tightness of the fit between the connecting seat 600 and the second shell 500 can be adjusted.
