Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a power rail and a rail socket. Background Technology

[0002] Track sockets are a new type of socket, mainly consisting of a power track (also called an electrical rail) and an adapter. The power track is mounted on a wall or desktop via its back panel, and the adapter is plugged into the power track.

[0003] In related technologies, the housing of the power rail has slots that provide insertion and removal channels for the adapter. These slots typically have protective doors, and torsion springs control the rotation of these doors. However, torsion springs are difficult to install, resulting in low assembly efficiency for current power rails. Utility Model Content

[0004] This utility model provides a power rail and a rail socket, which can improve the assembly efficiency of the power rail. The technical solution is as follows:

[0005] On the one hand, this utility model provides a power rail, which includes a housing and a protective door assembly;

[0006] The housing has a receiving cavity and a slot communicating with the receiving cavity;

[0007] The protective door assembly includes a protective door and an elastic element. The protective door is rotatably connected to the housing. The two ends of the elastic element in the extending direction abut against the inner walls of the protective door and the housing, respectively. The protective door closes the slot and can rotate into the receiving cavity after being pressed.

[0008] In one possible implementation, the protective door snaps into the slot, and the outer surface of the protective door is flush with the outer edge of the slot.

[0009] In one possible implementation, the protective door includes a door body, a pivot, and a connecting part.

[0010] The door body and the pivot are connected by the connecting part, and the door body, the pivot, and the connecting part are integrally formed.

[0011] In one possible implementation, the protective door assembly further includes a fixing member installed within the receiving cavity and located between the inner wall of the housing and the elastic member, such that one end of the elastic member abuts against the fixing member.

[0012] In one possible implementation, the protective door has a fixing groove, the fixing member has a first fixing post, one end of the elastic member is located in the fixing groove, and the other end is sleeved on the first fixing post.

[0013] In one possible implementation, the protective door has a second fixing post, the fixing member has a first fixing post, one end of the elastic member is sleeved on the second fixing post, and the other end is sleeved on the first fixing post.

[0014] In one possible implementation, the fastener has a first fixing groove and a second fixing groove spaced apart on the side near the slot, and the two ends of the rotating shaft are rotatably disposed in the first fixing groove and the second fixing groove, respectively.

[0015] In one possible implementation, the fastener has a protrusion on the side away from the slot, the protrusion being configured to abut against the door body after the door body is pressed, thereby restricting the door body from continuing to rotate into the receiving cavity.

[0016] In one possible implementation, the fastener has an abutting surface on the side near the slot that abuts against the inner wall of the housing.

[0017] In one possible implementation, there are multiple protective door assemblies arranged side by side along the extension direction of the slot.

[0018] On the other hand, the present invention provides a track socket, the track socket including a power track as described in one aspect above and at least one adapter, the power supply part of the adapter being able to be inserted into the housing via the slot.

[0019] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:

[0020] The power rail provided in this embodiment allows the protective door to rotate into the receiving cavity under the push of the adapter when it needs to be inserted into the housing through the slot. Simultaneously, the adapter compresses the elastic element located between the protective door and the inner wall of the housing in the extending direction, facilitating adapter insertion. When the adapter needs to be removed, the protective door can be pushed back to its original position by the elastic force of the elastic element. This power rail, by using elastic elements at both ends in the extending direction that abut against the protective door and the inner wall of the housing respectively, replaces the torsion spring in related technologies, making it easier to assemble and improving assembly efficiency.

[0021] It should be understood that the above general description and the following detailed description are merely exemplary and explanatory, and do not limit the present invention. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0037] It should be noted that, unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning as understood by a person of ordinary skill in the art to which this disclosure pertains.

[0038] In the description of this utility model, some directional terms are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In the embodiments of this utility model, terms such as "upper," "lower," and "side" are generally used to indicate orientation. Figure 1 The relative positions shown are based on the given information, and these directional terms are used only to more clearly describe the relationships between structures, not to describe absolute positions. Positions may change when the product is placed in different orientations; for example, "up" and "down" may be interchanged.

[0039] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0040] Figure 1 A schematic diagram of a power rail structure provided in an embodiment of this utility model is shown below. Figure 1 This utility model embodiment provides a power rail 1, which includes a housing 11 and a protective door assembly 12.

[0041] The housing 11 has a receiving cavity 111 and a slot 112 communicating with the receiving cavity 111; the protective door assembly 12 includes a protective door 121 and an elastic member 122. The protective door 121 is rotatably connected to the housing 11, and the two ends of the elastic member 122 in the extending direction abut against the inner wall of the protective door 121 and the housing 11, respectively; the protective door 121 closes the slot 112 to achieve dust prevention inside the housing 11, and can rotate into the receiving cavity 111 after being pressed.

[0042] In some embodiments, the elastic element 122 can be a spring. In this embodiment of the invention, when the spring is compressed to its compression limit, it yields inward to improve the space utilization of the protective door 121; when it rebounds to reset, it yields outward due to its own elasticity. Therefore, by utilizing the yielding deformation of the spring rebound, the function of flipping and resetting the protective door 121 is realized.

[0043] When the adapter needs to be inserted into the housing 11 through the slot 112 to draw power, the protective door 121 is pressed and rotates into the receiving cavity 111 under the push of the adapter, while compressing the elastic element 122 to facilitate the insertion of the adapter; when the adapter needs to be pulled out, the protective door 121 can be pushed and reset under the elastic force of the elastic element 122.

[0044] The power rail 1 provided in this embodiment replaces the torsion spring in the related art with elastic members 122, which are respectively disposed at both ends in the extending direction and abut against the inner walls of the protective door 121 and the housing 11. This makes the power rail 1 easier to assemble and improves assembly efficiency. At the same time, compared with the double-sided protective doors in the related art, the protective door assembly 12 has a simple structure and can be assembled independently and automatically, which can improve production efficiency and reduce manufacturing costs.

[0045] In some embodiments, see Figure 1 The protective door 121 is inserted into the slot 112, and the outer surface 1210 of the protective door 121 is flush with the outer edge of the slot 112. This makes the protective door 121 and the housing 11 of the power rail 1 provided in this embodiment of the present invention appear as a flat surface rather than as a slot or opening. Compared with the power rails in related technologies that have obvious slots, this not only improves the aesthetics of the power rail 1, but also prevents dust and other impurities from accumulating at the slot 112. This prevents impurities from entering the housing 11 when the protective door 121 rotates, thereby further ensuring that the power rail 1 will not be damaged by impurities and improving the safety of the power rail.

[0046] Figure 2 A schematic diagram of the structure of a protective door provided in an embodiment of this utility model is shown below. Figure 2In some embodiments, the protective door 121 includes a door body 1211, a pivot 1212, and a connecting part 1213, wherein the door body 1211 and the pivot 1212 are connected by the connecting part 1213, and the door body 1211, the pivot 1212, and the connecting part 1213 are integrally formed.

[0047] Thus, compared to the process of separately preparing the door body and the rotating shaft and then assembling them in related technologies, the power rail 1 provided in this embodiment of the present invention has fewer assembly steps, is easier to assemble, and improves assembly efficiency.

[0048] Figure 3 This is a structural schematic diagram of a protective door assembly provided in an embodiment of the present utility model. Figure 4 A disassembled schematic diagram of a protective door assembly provided for an embodiment of this utility model is shown below. Figure 1 , Figure 3 and Figure 4 In some embodiments, the protective door assembly 12 further includes a fixing member 123, which is installed in the receiving cavity 111 and located between the inner wall of the housing 11 and the elastic member 122, such that one end of the elastic member 122 abuts against the fixing member 123.

[0049] In other words, the protective door 121, the elastic element 122, and the fixing element 123 together constitute the protective door assembly 12. The fixing element 123 is fixedly disposed in the receiving cavity 111 of the housing 11 and is used to fix the elastic element 122 and the protective door 121.

[0050] Regarding the arrangement between the elastic element 122 and the protective door 121, the power rail 1 provided in this embodiment of the utility model offers two possible implementation methods:

[0051] In one possible implementation, see Figure 5 ,in Figure 5 This is a schematic diagram of a protective door and an elastic element provided in an embodiment of the present utility model. The protective door 121 has a fixing groove 1214, the fixing element 123 has a first fixing post 1231, one end of the elastic element 122 is located in the fixing groove 1214, and the other end is sleeved on the first fixing post 1231, so that the two ends of the elastic element 122 in its extension direction are fixed by the fixing groove 1214 and the first fixing post 1231 respectively.

[0052] For example, the fixing groove 1214 can be a cylindrical groove, which facilitates the installation of the elastic element 122.

[0053] In another possible implementation, the protective door 121 has a second fixing post (not shown in the figure), the fixing member 123 has a first fixing post 1231, one end of the elastic member 122 is sleeved on the second fixing post, and the other end is sleeved on the first fixing post 1231, so that the two ends of the elastic member 122 in its extension direction are fixed by the first fixing post 1231 and the second fixing post respectively.

[0054] Figure 6 A structural schematic diagram of a fastener provided in an embodiment of this utility model is shown below. Figure 6 and combined Figure 3 In some embodiments, the fixing member 123 has a first fixing groove 1232 and a second fixing groove 1233 spaced apart on the side near the slot 112, and the two ends of the rotating shaft 1212 are respectively rotatably disposed in the first fixing groove 1232 and the second fixing groove 1233. In this way, the protective door 121 and the fixing member 123 are rotatably connected.

[0055] Figure 7 This is a schematic diagram of another power rail structure provided in an embodiment of the present invention, wherein... Figure 7 The diagram shows multiple protective doors 121 flipping into the receiving cavity 111 after being pressed. See also... Figure 3 , Figure 6 and Figure 7 The fastener 123 has a protrusion 1234 on the side away from the slot 112. The protrusion 1234 is configured to abut against the door 1211 after the door 1211 is pressed, so as to limit the door 1211 from continuing to rotate into the receiving cavity 111 and prevent the door 1211 from failing or being damaged due to excessive rotation.

[0056] In some embodiments, see Figure 1 and Figure 6 The fixing member 123 has an abutment surface 1235 on the side near the slot 112, and the abutment surface 1235 abuts against the inner wall of the housing 11. By setting the abutment surface 1235, after the elastic member 122 resets the protective door 121 under the action of elastic force, the door body 1211 is restricted from continuing to rotate in the direction away from the receiving cavity 111, so as to prevent the door body 1211 from failing or being damaged due to excessive rotation.

[0057] It is understandable that the contact surfaces 1, 2, 3, and 4 are planes.

[0058] For example, see Figure 6 A contact surface 1235 is provided on the side of the first fixing groove 1232 and the second fixing groove 1233 opposite to the slot 112.

[0059] In some embodiments, see Figure 1The number of protective door assemblies 12 is multiple, and the multiple protective door assemblies 12 are arranged side by side along the extension direction of the slot 112.

[0060] In other words, each protective door 121 can rotate independently. Only the protective door 121 under adapter pressure rotates, rather than all protective doors 121 rotating synchronously. This avoids all protective doors 121 rotating synchronously every time an adapter is plugged in or unplugged, thus preventing damage from excessive rotation and improving the reliability of the protective door assembly 12. Furthermore, since only the protective door 121 under adapter pressure rotates, while the other protective doors 121 are in their initial closed slot 112 state, the opening area of ​​the slot 112 is reduced, decreasing the entry of external impurities into the housing 11. This provides better protection for the components inside the housing 11 and improves the safety of the power rail.

[0061] This utility model embodiment also provides a track socket, see [link / reference] Figure 8 and Figure 9 ,in Figure 8 This is a schematic diagram of the structure of a track socket provided in an embodiment of the present utility model. Figure 9 This is a split schematic diagram of a track socket provided in an embodiment of the present utility model. The track socket includes a power track 1 and at least one 2. The power take-off part 21 of the adapter 2 can be inserted into the housing 11 through the slot 112.

[0062] By adopting this power rail 1, the assembly efficiency of the power rail can be improved.

[0063] In this embodiment of the invention, the power rail 1 is a busbar device, which contains an L-pole conductive strip, an N-pole conductive strip, and an E-pole conductive strip, and is connected to the power connection line. When the power-taking part 21 of the adapter 2 passes through the slot 112, it can push the contacting protective door 121 to rotate into the receiving cavity 111, so that the power-taking part 21 enters the receiving cavity 111 and contacts the corresponding L-pole conductive strip, N-pole conductive strip, and E-pole conductive strip to take power.

[0064] Furthermore, there can be one or more adapters 2, and the power supply part 21 of each adapter 2 can be inserted into the receiving cavity 111 of the housing 11 via the slot 112. For example, Figure 8 and Figure 9 The example shown only illustrates the case where there is only one adapter 2.
