Description

Technical Field

[0001] This utility model relates to the field of electrified rail transit, and in particular to the joint of the contact rail. Background Technology

[0002] The contact rail system is a conductive system that transmits electrical energy to the vehicle through power receiving shoes, laid along the running rail. This system consists of multiple contact rail sections connected by intermediate joints to ensure continuity. Existing contact rail basic structures include C-shaped rails and I-shaped rails. The joint of the I-shaped rail, as disclosed in Chinese Utility Model Publication No. CN 223290702U, involves two symmetrically arranged connecting grooves that cover and fix the bottom of the I-shaped rail. The two grooves are connected and fixed together by fasteners through mounting holes. This method of fastening requires the bolts to be completely removed before the joint can be disassembled, which is very inconvenient for disassembly. Utility Model Content

[0003] To provide an I-shaped contact rail connector that is easy to disassemble, the technical solution adopted by this utility model is as follows:

[0004] An I-shaped contact rail connector includes a pair of mounting bases that can be combined and spliced ​​to cover the bottom of an I-shaped contact rail, and a fastener connecting the pair of mounting bases together. The mounting bases are provided with mounting grooves for mounting the fasteners. The mounting grooves are semi-open structures with the opening located on one side of the mounting base. The fasteners are provided with a locking plate that can engage with the mounting bases to prevent the fasteners from moving toward the opening.

[0005] Furthermore, the mounting groove is L-shaped.

[0006] Furthermore, the card holder is provided with a card slot for inserting the card plate.

[0007] Furthermore, a through hole is provided on the side of one of the card holders.

[0008] Furthermore, the end of the threaded connector in the through hole can abut against the screw on the opposite side of the mounting bracket.

[0009] Furthermore, the card holder is provided with a spring piece that contacts the bottom of the I-shaped contact rail and provides elastic support.

[0010] By adopting the above technical solution, since the mounting groove of the fastener is a semi-open structure with an opening on one side, the bolt can be loosened and then pulled out from the opening along the mounting groove for removal. The operation is convenient and quick. The clamping plate can also limit the bolt after tightening, preventing the bolt from automatically exiting from the opening position, so that the connection is stable and reliable.

[0015] To better understand the concept of this invention, the technical solution of this invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 The connector shown includes a pair of card holders 1, such as Figure 4 As shown, by placing the pair of card holders 1 on both sides of the bottom of the I-shaped contact rail and connecting them with fasteners 2, a covering and clamping fixation is formed on the bottom of the I-shaped contact rail. The connection part of the two I-shaped contact rails is connected through this joint. Therefore, after the pair of card holders 1 are spliced ​​and combined, the inside has a groove shape that basically matches the contour of the rail bottom.

[0017] like Figure 2 As shown, to connect the two card holders 1 via fasteners 2 and facilitate the removal of fasteners 2 from the card holders 1, a mounting groove 3 is provided on the card holder 1 for inserting the fasteners 2. The mounting groove 3 is a semi-open structure with one side open. Specifically, in this embodiment, the opening 3-1 of the mounting groove 3 is located on the bottom surface of the card holder 1. The mounting groove 3 is generally L-shaped. The fastener 2 is inserted through the opening 3-1 and moves along the groove to the inside for fastening. The removal process is the reverse. To prevent the fastener 2 from moving around in the mounting groove 3 after installation, a retaining plate 4 is also provided on the fastener 2. The retaining plate 4 can be engaged with the opening of the mounting groove 3. Thus, when the fastener 2 moves towards the opening of the mounting groove 3, it is restricted by the retaining plate 4. In other directions, it is restricted not only by the retaining plate 4 but also by the inner wall of the mounting groove, thereby preventing the fastener 2 from moving around in the mounting groove 3. Of course, a retaining groove 5 can also be provided on the card holder 1 so that the retaining plate 4 can be embedded therein to form a limiting position for the fastener 2. This will be explained in conjunction with other embodiments later.

[0018] The L-shaped mounting groove 3 facilitates the engagement of the clamping plate 4, and its complex channel structure also prevents the fastener 2 from easily detaching from the mounting groove 3 if it accidentally loosens. Therefore, the mounting groove 3 can also be in a more complex C-shape, etc., to better prevent bolts from accidentally loosening and detaching from the mounting groove.

[0019] Of course, for easier disassembly, mounting slot 3 can also be configured as follows: Figure 3As shown in the straight groove form, in this structure, in order to facilitate the snap-fit ​​of the clamping plate 4, a clamping groove 5 can be set on the clamping seat 1. After the fasteners 2 are tightened, the clamping plate 4 is embedded in the clamping groove 5, which limits the fasteners 2. The opening position of the mounting groove 3 can also be adjusted according to the actual layout. For example, when the mounting groove 3 of the straight groove form is located at both ends of the clamping seat, the opening 3-1 can be set on the end face of the clamping seat 1.

[0020] The structural forms of the mounting groove 3 based on the above two embodiments can be combined, such as a combination of L-shaped and straight grooves.

[0021] Since the clamping seat 1, secured to the contact rail by the fastener 2, may become stuck on the contact rail during removal, a through hole 6 is provided on the side of one of the clamping seats 1 to facilitate removal. The clamping seat 1 can be removed from the contact rail by inserting a pin into the through hole 6 and tapping it, or as... Figure 2 As shown, a screw rod 7 is threaded onto the through hole 6. By screwing the screw rod 7, one end of the screw rod is pressed against the opposite side of the retaining seat 1, thus disengaging the retaining seat 1 from the contact rail.

[0022] To ensure full contact between the inner cavity of the card holder 1 and the contact surfaces of the contact rail bottom, it is also possible to... Figure 2 As shown, a spring sheet 8 is provided on the inner surface of the card holder 1 to form an elastic support for the bottom surface of the rail, thereby applying elastic force to the rail bottom so that each surface of the rail bottom can fully contact the inner surface of the card holder 1, thus achieving better conductivity.
