[0033] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0034] Example 1

[0035] refer to Figure 1 As shown, an embodiment of the present application provides a connecting wire clamp structure 100 , which includes a mounting assembly 120 , a protective pad 130 and a pre-twisted wire member 140 .

[0036] Specifically, combined Figure 1 and Figure 2 As shown, the mounting assembly 120 includes a base 121, a cover 122 and a fixing member 123. The base 121 is arranged between the support frame 110 and the cover 122. One end of the cover 122 and one end of the base 121 can be adjustably mounted on the support frame 110 through the fixing member 123. The end of the cover 122 away from the fixing member 123 and the end of the base 121 away from the fixing member 123 are hinged and define a first accommodating channel 125; the connecting wire 150 is passed through the first accommodating channel 125, and the first accommodating channel 125 is penetrated by the connecting wire 150; the protective pad 130 can be sleeved on the connecting wire 150, and the protective pad The pad 130 is passed through the first accommodating channel 125; a partial area of the pre-twisted wire piece 140 is arranged between the protective pad 130 and the side wall of the first accommodating channel 125. When the connecting wire 150 vibrates or swings, the protective pad 130 and the pre-twisted wire piece 140 cooperate to weaken or offset the amplitude of the connecting wire 150. The protective pad 130 has a certain buffering and vibration energy absorption function. The installation component 120 is provided for easy installation and maintenance. The base 121 and the cover plate 122 of the installation component 120 are hinged and connected and fixed by the fixing member 123. The installation is simple, and the distance between the base 121 and the cover plate 122 can be adjusted by the fixing member 123.

[0037] As will be understood, connecting conductor 150 is used for power transmission. Pre-twisted wire 140 is a structural wire used to reinforce and increase tensile strength of connecting conductor 150. It is composed of multiple strands of metal wire pre-twisted into a spiral shape, forming a flexible yet strong structure. Protective pad 130 is placed on the outside of connecting conductor 150 to protect it from physical damage and environmental influences, while also reducing vibration and ensuring stable and safe power transmission. The pad material must have excellent insulation, wear resistance, and weather resistance.

[0038] It should be noted that the reference Figure 1 and Figure 4As shown, the connecting wire clamp structure 100 has a first direction. Exemplarily, the first direction is the length direction of the connecting wire 150 of the connecting wire clamp structure 100. It should be understood that the above definitions are merely for facilitating understanding of the relative positional relationships of the various components of the connecting wire clamp structure 100 and should not be construed as limiting this application.

[0039] In one embodiment, optionally, reference Figure 2 As shown, the cover 122 is hinged to the base 121 via a connecting shaft 124, so that the cover 122 rotates relative to the base 121 with the connecting shaft 124 as the axis. When the cover 122 and the base 121 rotate relative to each other, the installation assembly 120 is opened, which facilitates the installation of the protective pad 130 and the pre-twisted wire 140. After the installation is completed, the cover 122 and the base 121 are locked and fixed to the support frame 110 to achieve the fixation and limitation of the connecting wire 150. Optionally, in combination with Figure 1 and Figure 4 As shown, the pre-twisted wire member 140 includes a backtwisting section 141 and a pre-twisting section 142. The opposite ends of the backtwisting section 141 are connected to the pre-twisting section 142. That is, the middle part of the pre-twisting wire member 140 is the backtwisting section 141. The backtwisting section 141 and the pre-twisting section 142 together form a pre-twisted structure, providing protection for the connecting wire 150.

[0040] In summary, when the connecting wire 150 in the connecting wire clamp structure 100 vibrates or swings, the protective pad 130 and the pre-twisted wire part 140 cooperate to weaken or offset the amplitude of the connecting wire 150. The protective pad 130 has a certain buffering and vibration energy absorption function. The installation component 120 is provided for easy installation and maintenance. The base 121 and the cover 122 of the installation component 120 are hinged and connected and fixed by the fixing member 123. The installation is simple, and the distance between the base 121 and the cover 122 can be adjusted by the fixing member 123, thereby improving the installation efficiency of the connecting wire clamp structure 100.

[0041] Example 2

[0042] refer to Figure 1 As shown, an embodiment of the present application provides another connecting wire clamp structure 100 , which includes a mounting assembly 120 , a protective pad 130 and a pre-twisted wire member 140 .

[0043] Specifically, combined Figure 1 and Figure 2As shown, the mounting assembly 120 includes a base 121, a cover 122 and a fixing member 123. The base 121 is arranged between the support frame 110 and the cover 122. One end of the cover 122 and one end of the base 121 can be adjustably mounted on the support frame 110 through the fixing member 123. The mounting assembly 120 is arranged to facilitate installation and maintenance. The base 121 and the cover 122 of the mounting assembly 120 are hinged and connected and fixed by the fixing member 123. The installation is simple, and the distance between the base 121 and the cover 122 can be adjusted through the fixing member 123.

[0044] In this embodiment, reference Figure 2 and Figure 3 As shown, the end of the cover plate 122 away from the fixing member 123 is hinged to the end of the base 121 away from the fixing member 123 and defines a first accommodating channel 125, through which a connecting wire 150 is passed. The protective pad 130 can be sleeved on the connecting wire 150, and the protective pad 130 is passed through the first accommodating channel 125; a part of the pre-twisted wire member 140 is arranged between the protective pad 130 and the side wall of the first accommodating channel 125. When the connecting wire 150 vibrates or swings, the protective pad 130 and the pre-twisted wire member 140 cooperate to weaken or offset the amplitude of the connecting wire 150. The protective pad 130 has a certain buffering and vibration energy absorption effect, reducing fatigue fracture or damage of the connection node of the connecting wire clamp structure 100 and preventing safety risks.

[0045] Exemplarily, the connecting wire 150 can be a ground wire, and accordingly, the support frame 110 can be one of a ground wire tray, a shoulder frame or a channel steel base 121, so that the connecting wire clamp structure 100 can be used to fix the ground wire on the ground wire tray, shoulder frame or channel steel base 121.

[0046] It should be noted that the reference Figure 1 and Figure 4 As shown, the connecting clamp structure 100 has a first direction. Exemplarily, the first direction is the length direction of the connecting wire 150 of the connecting clamp structure 100.

[0047] In one embodiment, optionally, reference Figure 2As shown, the cover plate 122 is hingedly connected to the base 121 via a connecting shaft 124, so that the cover plate 122 rotates relative to the base 121 about the connecting shaft 124. When the cover plate 122 and the base 121 rotate relative to each other, the installation assembly 120 is opened, facilitating the installation of the protective pad 130 and the pre-twisted wire 140. After installation is completed, the cover plate 122 and the base 121 are locked and fixed to the support frame 110 to achieve the fixation and position limiting of the connecting wire 150. Exemplarily, the connecting shaft 124 is a pin, and the cover plate 122 and the base 121 are provided with corresponding through holes and connected by the pin.

[0048] Further, combined with Figure 2 and Figure 3 As shown, the base 121 is provided with a first mounting groove 1211 and a second mounting groove 1212 at one end away from the fixing member 123. The first mounting groove 1211 and the second mounting groove 1212 are arranged opposite to each other. The cover 122 is provided with a connecting member 1221. The connecting shaft 124 can be passed through the through hole of the connecting member 1221, and the opposite ends of the connecting shaft 124 are respectively engaged with the first mounting groove 1211 and the second mounting groove 1212. In other words, a connecting shaft 124 is used to pass through the through hole of the connecting member 1221. The cover 122 is provided with a hole, and the opposite ends of the connecting shaft 124 are respectively engaged with the first mounting groove 1211 and the second mounting groove 1212, so that the cover 122 and the base 121 can rotate relative to each other via the connecting shaft 124. That is, the connection structure of the connecting shaft 124 is a single-axis through-type hinge structure, which is convenient for opening or locking by flipping. The protective pad 130, pre-twisted wire member 140, and connecting wire 150 can all be installed in the first accommodating channel 125 and then locked. The connection structure of the connecting shaft is relatively firm and stable. Exemplarily, the connecting member 1221 is located between the first mounting groove 1211 and the second mounting groove 1212.

[0049] Optionally, the fixing member 123 is an adjusting bolt, the cover plate 122 is provided with a first mounting hole, the base 121 is provided with a second mounting hole, and the support frame 110 is provided with a third mounting hole. The adjusting bolt can be sequentially passed through the first mounting hole, the second mounting hole and the third mounting hole and connected with the nut. Accordingly, the distance between the cover plate 122 and the base 121 can be adjusted by the adjusting bolt. There is no need to remove all the adjusting bolts, and the installation of the protective pad 130 and the pre-twisted wire member 140 can also be achieved, which has a faster installation effect.

[0050] In one embodiment, optionally, in combination Figure 1 and Figure 4As shown, the pre-twisted wire member 140 includes a backtwisting section 141 and a pre-twisting section 142. The opposite ends of the backtwisting section 141 are connected to the pre-twisting section 142. That is, the middle part of the pre-twisting wire member 140 is the backtwisting section 141. The backtwisting section 141 and the pre-twisting section 142 together form a pre-twisted structure, providing protection for the connecting wire 150.

[0051] Optionally, the pre-twisted section 142 is wrapped around the connecting wire 150, providing protection for the connecting wire 150. The detwisting section 141 is disposed between the protective pad 130 and the sidewall of the first accommodating channel 125, that is, between the mounting assembly 120 and the protective pad 130. The detwisting section 141 eliminates the spiral twisting to facilitate a straighter installation and connection with the mounting assembly 120 and the protective pad 130. The detwisting section 141 locates the installation position, reducing installation complexity and thereby improving construction efficiency. The detwisting section 141 achieves the purpose of supporting and connecting the connecting wire 150. Exemplarily, the pre-twisted wire member 140 is made of copper alloy to reduce electrochemical corrosion of the connecting wire 150 and increase the service life of the connecting wire clamp structure 100.

[0052] In one embodiment, optionally, Figure 1 and Figure 2 As shown, the protective pad 130 includes a first pad and a second pad, the first pad and the second pad are symmetrically arranged, the first pad is connected to the second pad and defines a second accommodating channel 132, so that the connecting wire 150 can be passed through the second accommodating channel 132, in other words, the first pad and the second pad are engaged with each other, so that the first pad and the second pad cover the connecting wire 150, separate the connecting wire 150 and the installation component 120, and play a protective and isolating role.

[0053] Optionally, combined Figure 5 and Figure 6 As shown, a limiting protrusion 131 is provided on the side of the first pad away from the second pad, and a limiting protrusion 131 is provided on the side of the second pad away from the first pad. The limiting protrusion 131 can abut against the backtwist section 141. The limiting protrusion 131 limits the position of the pre-twisted wire member 140, thereby reducing the swinging or vibration of the connecting wire 150. Exemplarily, the number of limiting protrusions 131 on both the first pad and the second pad is two, and the backtwist section 141 is provided between the two limiting protrusions 131. The two oppositely disposed limiting protrusions 131 can limit and fix the pre-twisted wire member 140.

[0054] Alternatively, as Figure 5As shown, the first pad and the second pad are both dumbbell-shaped structures, and the limiting protrusions 131 are respectively arranged at the middle position of the first pad and the second pad, that is, the first pad and the second pad are connected and buckled to form a dumbbell-shaped structure. The dumbbell-shaped protective pad 130 causes the pre-twisted wire piece 140 to shrink to the middle position of the protective pad 130 and is fixed by the installation component 120 to prevent the connecting wire 150 and various components from being offset and misaligned.

[0055] Optionally, the protective pad 130 is made of ethylene propylene rubber or silicone rubber. Both ethylene propylene rubber and silicone rubber have good insulation, temperature resistance and aging resistance, so as to improve the adaptability of the protective pad 130 and extend the service life of the protective pad 130.

[0056] Example 3

[0057] An embodiment of the present invention also provides a rail transit system, which may be an electrified railway rail transit system or other types of rail transit systems, including the connecting wire clamp structure 100 in Example 1 or Example 2. The rail transit system including the connecting wire clamp structure 100 has all the beneficial effects of the connecting wire clamp structure 100, which will not be described in detail here.

[0058] In all examples shown and described herein, any specific values should be interpreted as merely exemplary and not limiting, and thus other examples of the exemplary embodiments may have different values.

[0059] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
