[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0029] Example 1

[0030] See also Figures 1 to 4 As shown, this embodiment discloses an adapter, including a main body, the main body including a base frame 1 and an E-pole grounding piece 2 that can move in a direction close to or away from the base frame 1, one end of the E-pole grounding piece 2 away from the base frame 1 forms a grounding end 21 for contacting or connecting with the grounding conductor 72 of the power-carrying rail 7, an E-pole conductive piece 3 for contacting or connecting with the grounding conductive part of an external electrical appliance is provided between the base frame 1 and the E-pole grounding piece 2, the E-pole conductive piece 3 is provided with an elastic arm 31 that can swing in a direction close to or away from the base frame 1, the elastic arm 31 is in contact with or connected to the E-pole grounding piece 2, and an elastic piece for driving the elastic arm 31 to swing in a direction close to the base frame 1 is abutted between the base frame 1 and the elastic arm 31.

[0031] In the absence of external force, the elastic arm 31 of the E-pole conductive member 3 swings in the direction away from the base frame 1 under the action of the elastic member, and the elastic arm 31 abuts against the end of the E-pole grounding member 2 close to the base frame 1. At the same time, the grounding end 21 of the E-pole grounding member 2 is in the limit position of the moving stroke away from the base frame 1 under the action of the elastic arm 31 (hereinafter referred to as the "first limit position").

[0032] After the adapter is installed on the power-carrying rail 7, the grounding end 21 of the E-pole grounding piece 2 is abutted against the grounding conductor 72 of the power-carrying conductor, overcoming part of the elastic force of the elastic piece, and the elastic piece is compressed and retracted. At the same time, the elastic piece imparts a force to the grounding end 21 of the E-pole grounding piece 2 in a direction away from the base frame 1 through the elastic arm 31, so that there is sufficient contact force between the grounding end 21 of the E-pole grounding piece 2 and the grounding conductor 72 of the power-carrying rail 7 under the action of the elastic piece, and the grounding end 21 and the grounding conductor 72 of the power-carrying rail 7 are tightly abutted together.

[0033] After the adapter is removed, the E-pole grounding piece 2 loses the external force of the grounding conductor 72 of the energized conductor, and the elastic piece extends outward again, driving the E-pole grounding piece 2 to move away from the base frame 1 until the E-pole grounding piece 2 returns to the first extreme position.

[0034] In this embodiment, an elastic arm 31 is provided on the E-pole conductive member 3, and the E-pole conductive member 3 realizes power transmission and conduction through the elastic arm 31 and the E-pole grounding member 2. An elastic member is provided between the base frame 1 and the elastic arm 31. Under the action of the elastic member, the elastic arm 31 always has a tendency to swing in the direction away from the base frame 1. On the one hand, the E-pole conductive member 3 and the E-pole grounding member 2 can always realize good transmission and conduction. On the other hand, the elastic member imparts a force in the direction away from the base frame 1 (that is, a force toward the grounding conductor 72 of the power-carrying rail 7) to the E-pole grounding member 2 through the elastic arm 31. After the adapter is inserted into the power-carrying rail 7, there is sufficient contact force between the grounding end 21 of the E-pole grounding member 2 and the grounding conductor 72 of the power-carrying rail 7 under the action of the elastic member. The grounding end 21 and the grounding conductor 72 of the power-carrying rail 7 are tightly abutted together, thereby ensuring the stability of the contact and conductive performance between the E-pole grounding member 2 and the grounding conductor 72 of the power-carrying rail 7, ensuring the stability of the grounding of the adapter, and high safety.

[0035] See also Figures 4 to 7 As shown, the E-pole conductive member 3 includes a base 32, the base 32 is provided with a hollow groove 33, the side wall of the base 32 is bent toward the direction close to the hollow groove 33 to form an elastic arm 31, the elastic arm 31 includes a connecting end 311 and a swinging end 313, a top end 312 is provided between the connecting end 311 and the swinging end 313, one end of the elastic member passes through the hollow groove 33 and abuts against the top end 312, and the swinging end 313 is in contact with or connected to the E-pole grounding member 2.

[0036] In this embodiment, an elastic arm 31 is provided on the base 32, and the restoring force of the elastic member is transmitted to the E-pole grounding member 2 through the elastic arm 31. After the adapter is inserted into the power-carrying rail 7, it is ensured that there is sufficient contact force between the grounding end 21 of the E-pole grounding member 2 and the grounding conductor 72 of the power-carrying rail 7 under the action of the elastic member. At the same time, the swinging end 313 of the elastic arm 31 moves synchronously with the E-pole grounding member 2, ensuring that the E-pole conductive member 3 and the E-pole grounding member 2 can always achieve good transmission and conduction, thereby ensuring the stability of the grounding path.

[0037] See also Figures 4 to 6 As shown, an elastic clamping portion 34 for clamping a grounding conductive portion of an external electrical appliance is provided at one end of the base 32 away from the E-pole grounding member 2, and a base frame 1 is provided with a mounting groove 11 for mounting the base 32, and a mounting column 12 for mounting an elastic member is provided in the mounting groove 11, and the mounting column 12 at least partially extends into the hollow groove 33, and an end of the mounting column 12 away from the base frame 1 forms a limit end 13 for limiting the swing stroke of the elastic arm 31, and an avoidance hole for the elastic clamping portion 34 to pass through the mounting groove 11 is provided at the bottom of the mounting groove 11. In this embodiment, the elastic member is a column spring, and the elastic member is sleeved outside the mounting column 12.

[0038] By setting the mounting groove 11, it is ensured that the base 32 of the E-pole conductive component 3 is firmly installed on the base frame 1. The mounting column 12 is arranged in the hollow groove 33, so that the installation of the elastic component can be realized, and the swing stroke of the elastic arm 31 can be limited, thereby limiting the moving stroke of the E-pole grounding component 2 in the direction close to the base frame 1, thereby preventing the E-pole grounding component 2 from falling off. The overall structure is simple and the layout is compact.

[0039] See also Figure 2 and Figure 8 As shown, the main body is also provided with an insulating covering member 5, and the insulating covering member 5 is provided with a sliding guide groove 51. The E-pole grounding member 2 is slidably arranged in the sliding guide groove 51, and an extension opening for the E-pole grounding member 2 to extend out is provided at one end of the sliding guide groove 51 away from the base frame 1. The movement of the E-pole grounding member 2 is guided and limited by the sliding guide groove 51 to ensure the moving direction and resetting of the E-pole grounding member 2.

[0040] See also Figure 2 and Figure 4 As shown, a limiting step surface for limiting the sliding stroke of the E-pole grounding member 2 is provided in the sliding guide groove 51, and the E-pole grounding member 2 is provided with a limiting end surface 22 for contacting and limiting the position with the limiting step surface.

[0041] When the limiting end surface 22 of the E-pole grounding piece 2 abuts against the limiting step surface, the E-pole grounding piece 2 reaches the first limit position and can no longer move in a direction away from the base frame 1, thereby preventing the E-pole grounding piece 2 from falling out of the sliding guide groove 51.

[0042] See also Figure 2 and Figure 4 As shown, the E-pole grounding member 2 and the sliding guide groove 51 are relatively fixed in the circumferential direction, and the E-pole grounding member 2 is a columnar structure, the columnar structure includes a first column section 23 and a second column section 24 arranged in sequence away from the base frame 1, and the limiting end face 22 is arranged between the first column section 23 and the second column section 24. The sliding guide groove 51 is provided with a first guide groove section and a second guide groove section in sequence in the direction away from the base frame 1. The cross-sections of the first guide groove section and the first column section 23 are both rectangular structures, and the cross-sections of the second guide groove section and the second column section 24 are both circular structures. Among them, the rectangular structure can be a rectangular structure with right angles or rounded corners. In this embodiment, the corners of the rectangular structure are rounded to reduce the friction caused by the relative movement between the components.

[0043] In this embodiment, by providing a first guide groove section and a first column section 23 with a rectangular cross-section structure, the E-pole grounding piece 2 and the sliding guide groove 51 are circumferentially relatively fixed. At the same time, a limiting end face 22 can be naturally formed between the first column section 23 and the second column section 24 with different cross-sectional shapes. The overall structure is simple and easy to produce.

[0044] See also Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the main body is also provided with an N-pole power taking component 6A and an L-pole power taking component 6B, the insulating sheath 5 is provided with a sheathing portion, and the N-pole power taking component 6A and the L-pole power taking component 6B are both provided with a main body section 61 sheathed in the sheathing portion and an exposed section 62 exposed outside the sheathing portion, the exposed section 62 is provided at both ends of the main body section 61 in the length direction, and the exposed section 62 includes a power taking end 63 for connecting or contacting with the pole power rail 71 of the power-carrying rail 7.

[0045] The main sections 61 of the N-pole power taking component 6A, the L-pole power taking component 6B and the E-pole grounding component 2 are covered by the covering portion of the insulating covering 5, leaving only the exposed sections 62 that need to be exposed for grounding connection, further improving the safety of use and integrating the N-pole power taking component 6A, the L-pole power taking component 6B and the E-pole grounding component 2 into a whole, making the overall structure simpler and stronger.

[0046] See also Figure 3 , Figure 5 and Figure 8 As shown, the power supply terminal 63 includes an N-pole power supply terminal 63A and / or an L-pole power supply terminal 63B.

[0047] The power taking end 63 is a plug set, which includes a first contact piece and a second contact piece parallel to each other, and an insertion gap 631 is formed between the first contact piece and the second contact piece for the polar power rail 71 of the power rail 7 to be inserted.

[0048] In this embodiment, both the N-pole power-taking terminal 63A and the L-pole power-taking terminal 63B are plug-in components.

[0049] In the prior art, the power-taking part of the adapter is usually set as a pin of a sheet structure, and the polar power rail of the power-carrying rail is set as a socket of a U-shaped structure. This setting method requires more conductive material to form a socket with a certain length on the power-carrying rail for the adapter to slide freely to draw power. The amount of conductive material required to prepare the socket is more, especially the conductive material usually needs to be made of relatively expensive copper and its alloy materials, the material cost is high, and the overall weight of the track socket is greater.

[0050] In this embodiment, the power supply end 63 of the adapter is set as a plug kit. When in use, the polar power rail 71 of the power rail 7 is correspondingly set as a sheet-shaped plug member. When in use, the polar power rail 71 in the power rail 7 is inserted into the insertion gap 631 of the corresponding plug kit to achieve conductivity, thereby effectively reducing the amount of conductive material required for preparing the polar power rail 71. The total amount of conductive material required for the polar power rail 71 and the power supply end 63 is much smaller than the prior art, which can greatly reduce the material cost and effectively reduce the overall weight of the track socket without affecting the total power supply.

[0051] On the other hand, this embodiment discloses a track socket, including a power rail 7 and the above-mentioned adapter, the adapter is slidably arranged on the power rail 7, and the power rail 7 is provided with a grounding conductor 72 for cooperating with the E-pole grounding piece 2 to form grounding.

[0052] The power rail 7 is provided with an inner cavity, in which an N-pole power rail 71A and an L-pole power rail 71B are provided. Both the N-pole power rail 71A and the L-pole power rail 71B are in a sheet-like structure.

[0053] Example 2

[0054] The difference between this embodiment and embodiment 1 is that the power taking end includes an N-pole power taking end and / or an L-pole power taking end, and the power taking end is a sheet-shaped plug-in piece, and the plug-in piece is provided with an insertion end for extending into the polar power rail of the power rail;

[0055] The power rail is provided with an inner cavity, in which an N-pole power rail and an L-pole power rail are arranged. Both the N-pole power rail and the L-pole power rail are slot parts with slots, and the insertion end is inserted into the slot.

[0056] Of course, the above illustrations are only preferred implementation modes of the present utility model, and are not intended to limit the scope of use of the present utility model. Therefore, any equivalent changes made to the principle of the present utility model should be included in the protection scope of the present utility model.
