[0029] The following will be combined with the accompanying drawings of the specification Figures 1-7 to detail the specific embodiments of the present application. It should be understood that these specific descriptions are only used to teach those skilled in the art how to implement the present application, and are not used to exhaust all feasible ways of the present application, nor to limit the scope of the present application. Embodiment 1:

[0030] The following is combined with the accompanying drawings of the specification Figures 1-4 to describe the track socket according to the first embodiment of the present application.

[0031] Referring to Figures 1-3 , the detachable terminal 105 according to the first embodiment of the present application includes a fixed terminal block 1 and a movable terminal block 2 detachably mounted on the fixed terminal block 1. The movable terminal block 2 is connected to the mains power supply, and the fixed terminal block 1 is connected to the conductive conductor 102 in the power rail 100. When the movable terminal block 2 is mounted on the fixed terminal block 1, the movable terminal block 2 is electrically connected to the fixed terminal block 1, and the power of the mains power supply can be sequentially transmitted to the conductive conductor 102 of the power rail 100 through the movable terminal block 2 and the fixed terminal block 1.

[0032] In this embodiment, as Figure 2 , Figure 3 shown, the fixed terminal block 1 includes a fixed terminal housing 11 and a fixed terminal conductor 12. The fixed terminal housing 11 is an insulator, preferably made of plastic material. It includes a bottom plate and a vertical plate. The vertical plate is integrally formed at one end of the bottom plate and is perpendicular to the bottom plate. The bottom plate is mounted on the rail housing 101 of the power rail 100, and the fixed terminal conductor 12 is penetrated and arranged on both sides of the vertical plate. The fixed terminal conductor 12 is provided with three, namely the live wire fixed terminal conductor 12, the neutral wire fixed terminal conductor 12 and the ground wire fixed terminal conductor 13; the ground wire fixed terminal conductor 13 is placed between the live wire fixed terminal conductor 12 and the neutral wire fixed terminal conductor 12.

[0033] Referring toFigures 2-4 Any fixed wiring conductor 12 includes a U-shaped portion 121 and a plug portion 122. The plug portion 122 is integrally formed with the U-shaped portion 121. The bottom of the U-shaped portion 121 is embedded in the bottom plate, and the opening direction of the U-shaped portion 121 is in the direction away from the bottom plate. The plug portion 122 is integrally connected to one side of the bottom of the U-shaped portion 121 and is parallel to the bottom of the U-shaped portion 121. One end of the plug portion 122 away from the U-shaped portion 121 extends through the vertical plate, and the end of the plug portion 122 that passes through the vertical plate is used for plugging and connecting with the conductive conductor 102 in the power rail 100. The opening cross-section of the U-shaped portion 121 gradually decreases and then increases in the direction away from its own bottom, so as to facilitate the insertion of the movable wiring conductor 22 into the U-shaped portion 121, while maintaining the stable clamping of the movable wiring conductor 22 by the U-shaped portion 121.

[0034] Reference Figures 2-4 The insert portion 122 of the ground wire fixed connection conductor 13 is also provided with a grounding hole 131, and a conductive member (not shown in the figure) is inserted into the grounding hole 131. The conductive member is usually a metal screw. When the detachable terminal 105 is installed in the power track 100, the conductive member penetrates and connects the metal track housing 101 of the power track 100, thereby achieving grounding of the track housing 101 of the power track 100 and improving the safety of the use of the power track 100.

[0035] In this embodiment, refer to Figures 2-4 The movable wiring seat 2 includes a movable wiring shell 21 and a movable wiring conductor 22. The movable wiring shell 21 is an insulator, preferably made of plastic, and includes a wiring shell and a plug-in shell, which are integrally formed. The wiring shell is a groove-shaped structure with one end open, and a wiring cavity 24 is formed in the internal hollow portion. A cover plate 25 is mounted on the open end of the wiring cavity 24 by snap-fitting. The cover plate 25 can be detachably mounted on the wiring shell by snap-fitting, so as to achieve the closure and covering of the opening of the wiring cavity 24. A plug-in cavity is formed in the plug-in shell, and the plug-in cavity is connected to the outside at both the end of the plug-in shell away from the wiring shell and the end of the plug-in shell away from the cover plate 25.

[0036] There are three movable wiring conductors 22, namely a live wire movable wiring conductor 22 connected to the live wire, a neutral wire movable wiring conductor 22 connected to the neutral wire, and a ground wire movable wiring conductor 22 connected to the ground wire, wherein the ground wire movable wiring conductor 22 is arranged between the live wire movable wiring conductor 22 and the neutral wire movable wiring conductor 22.

[0037] Any movable connection conductor 22 includes a terminal 221 and a connection block 222, and the terminal 221 and the connection block 222 are integrally formed. The terminal 221 is placed in the connection cavity 24 of the connection housing, the connection block 222 is placed in the insertion cavity of the insertion housing, and the connecting portion of the terminal 221 and the connection block 222 penetrates through the connecting portion of the connection housing and the insertion housing. Two partitions are integrally formed on the insertion housing, and the two partitions are placed in the insertion cavity, dividing the insertion cavity into three spaces, and the connection block 222 is placed in the space formed by the three partitions.

[0038] Referring to Figures 2-4 , the terminal 221 is a hollow barrel-shaped structure made of a conductive material, preferably copper. Threaded holes are provided on the outer peripheral wall of the terminal 221 to facilitate the insertion of screws. When using the terminal 221 for wiring, first insert the conductive inner core of the wire into the cavity inside the terminal 221, and then rotate the screw. The screw presses the conductive inner core tightly in the cavity inside the terminal 221, thus realizing the wiring of the terminal 221. To improve the fastening effect of the screw on the conductive inner core of the wire in the cavity of the terminal 221, multiple threaded holes can be arranged along the axial direction of the terminal 221. Multiple screws act together to press the wire tightly on the terminal 221, further improving the stability of the connection between the wire and the terminal 221.

[0039] The connection block 222 is a rectangular block structure made of a conductive material. When the movable connection base 2 is installed on the fixed connection base 1, the connection block 222 is inserted and installed in the U-shaped portion 121 of the fixed connection conductor 12, thereby realizing the movable electrical connection between the movable connection conductor 22 and the fixed connection conductor 12.

[0040] Referring to Figure 2 、 Figure 3 , an insertion plate 3 is integrally formed on the bottom plate of the fixed connection housing 11. The insertion plate 3 is arranged on the same side of the vertical plate and in the same direction as the vertical plate. The plate surface of the insertion plate 3 is perpendicular to both the plate surface of the bottom plate and the plate surface of the vertical plate. The number of the insertion plates 3 is set to two, and the two insertion plates 3 are arranged in parallel with each other, and the two insertion plates 3 are placed on both sides of the U-shaped portions 121 of the three fixed connection conductors 12.

[0041] Referring to Figure 2 、 Figure 3, on both sides in the width direction of the insertion housing of the movable connection housing 21, insertion slots 4 are provided. The insertion slots 4 correspond to the insertion plates 3, and the opening direction of the insertion slots 4 is along the thickness direction of the insertion housing, that is, the opening direction of the insertion slots 4 is along the access direction of the movable connection housing 21 to the fixed connection housing 11. When the movable connection base 2 is inserted and installed on the fixed connection base 1, the movable connection base 2 is installed in the direction close to the fixed connection base 1 along the axial direction of the insertion plate 3 until the insertion slots 4 completely sleeve the outer periphery of the insertion plate 3 (or the insertion plate 3 is completely inserted into the insertion slots 4). At this time, the connection housing is in contact with the bottom plate. By using the insertion fit between the insertion plate 3 and the insertion slots 4, the detachable installation of the movable connection base 2 on the fixed connection base 1 is realized, and at the same time, the positioning of the movable connection base 2 on the fixed connection base 1 is realized, which is beneficial to maintaining the positioning insertion fit between the movable connection conductor 22 and the fixed connection conductor 12; at the same time, the stable installation of the movable connection base 2 on the fixed connection base 1 is realized, which is beneficial to maintaining the connection stability between the movable connection conductor 22 and the fixed connection conductor 12.

[0042] Refer to Figure 2 , Figure 3 , on both sides in the width direction of any insertion plate 3, anti-disengagement edges 5 are integrally formed. The axis of the anti-disengagement edges 5 is parallel to the axis of the insertion plate 3. The thickness of the anti-disengagement edges 5 is smaller than the thickness of the insertion plate 3, and the side wall in the thickness direction of the anti-disengagement edges 5 is flush with the side wall of the insertion plate 3 close to the other insertion plate 3. That is, the overall shape formed by the insertion plate 3 and the anti-disengagement edges 5 is a boss shape.

[0043] Refer to Figure 2 , Figure 3 , on both sides in the width direction of any insertion slot 4, anti-disengagement grooves 6 are formed. The axis of the anti-disengagement grooves 6 is parallel to the axis of the insertion slot 4. The structure of the anti-disengagement grooves 6 is adapted to the structure of the anti-disengagement edges 5. The anti-disengagement grooves 6 are arranged on one side of the insertion slot 4 close to the other anti-disengagement groove 6 in the lateral direction. That is, the setting position of the anti-disengagement grooves 6 on the insertion slot 4 is adapted to the setting position of the anti-disengagement edges 5 on the insertion plate 3. That is, the overall virtual structure shape formed by the anti-disengagement edges 5 and the anti-disengagement grooves 6 is a boss shape, which is just adapted to the specific structure formed by the insertion plate 3 and the anti-disengagement edges 5. When the insertion plate 3 is inserted and fitted with the insertion slot 4, the anti-disengagement edges 5 are simultaneously inserted and fitted with the anti-disengagement grooves 6. By providing the anti-disengagement edges 5 and the anti-disengagement grooves 6, and using the insertion fit between the anti-disengagement edges 5 and the anti-disengagement grooves 6, the insertion plate 3 is stably positioned in the insertion slot 4 to prevent the insertion plate 3 and the insertion slot 4 from disengaging along the opening direction of the insertion slot 4.

[0044] The implementation principle of Embodiment 1 is as follows: By setting the wiring terminal 105 separately into a fixed wiring base 1 and a movable wiring base 2, when the wiring terminal 105 is electrified, first take out the movable wiring base 2 alone, then connect the power cord to the movable wiring conductor 22, and then use the plug-in board 3 and the plug-in slot 4 structure to plug and install the movable wiring base 2 on the fixed wiring base 1. During the plugging process, the movable wiring conductor 22 is in electrical contact and connection with the fixed wiring conductor 12, and the external power supply is transmitted to the fixed wiring base 1 through the movable wiring base 2, realizing the electrification of the fixed wiring base 1. Thus, when the wiring terminal 105 is installed in the power rail 100, the electrified fixed wiring base 1 can supply power to the conductive conductor 102 in the power rail 100. Embodiment 2:

[0045] The following is combined with the specification appendix Figures 5-7 to illustrate the track socket according to the second embodiment of the present application.

[0046] Referring to Figures 5-7 , the track socket may include one or more adapters and a power rail 100. The adapter can be installed on the power rail 100 via an opening on the power rail 100. The power rail 100 can guide the adapter to slide, so that the position of the adapter can be flexibly adjusted. It can be understood that although Figure 5 only one adapter is shown, the number of adapters is not limited to one, for example, it can be two or three or more. When multiple adapters are installed on the power rail 100, the positions of the multiple adapters can be adjusted independently of each other.

[0047] Referring to Figures 5-7 , the power rail 100 includes a rail housing 101, an insulating bracket 103 installed in the rail housing 101, a conductive conductor 102 installed in the insulating bracket 103, the wiring terminal 105 disclosed in Embodiment 1, and end caps 104 installed at both ends of the rail housing 101 by screws. The wiring terminal 105 is arranged in the rail housing 101, one end of which abuts against the end cap 104, and the other end abuts against the insulating bracket 103 and the conductive conductor 102. The fixed wiring conductor 12 of the detachable wiring terminal 105 is clamped by the conductive conductor 102, thereby realizing the power supply of the wiring terminal 105 to the conductive conductor 102. Other structures of the power rail 100 except the wiring terminal 105 are prior arts and will not be elaborated here.

[0048] By installing the detachable terminal 105 inside the power rail 100, when wiring the power rail 100, the movable terminal block 2 can be first removed for wiring, and then the movable terminal block 2 can be installed on the fixed terminal block 1, so as to realize the power connection between the power rail 100 and the power supply. This wiring method facilitates adjusting the wiring posture of the movable terminal block 2 for convenient wiring, and the power rail 100 will not affect the wiring due to its large volume and mass, improving the problem of inconvenient wiring of the terminal 105 of the power rail 100.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
