[0002] In current projects, the equipment terminal boards on both sides of the cross-circuit fittings are generally divided into three phases, as shown in the attached manual. Figure 1 As shown, there are three-way pipe mothers. Because the distances a and b between the three phases A, B, and C of the devices 1 and 2 on both sides are different, a distance difference and angle will also be generated in the direction perpendicular to the pipe mother. It is necessary to match the tube mother angle through the transition of the cross-road hardware.

[0003] Therefore, a cross-circuit fitting is needed to be compatible with the angle and height between the terminal boards of the two devices. Utility Model Content

[0004] The utility model aims to provide a cross-circuit fitting to accommodate the angle and height between two equipment terminal boards.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] The first tube female hardware component includes a first fixing frame connected to the left fixing plate through a first telescopic joint, a first tube female clamp fixed to the first fixing frame, a first screw fixed to the left fixing plate, two first nuts threadedly sleeved on the top surface of the first screw, and a first universal joint connecting the first screw and the first fixing frame;

[0008] One end of the first universal joint is sleeved on the first screw rod and is placed between two first nuts;

[0009] The second tube mother hardware component includes a second fixing frame connected to the right fixing plate through a second telescopic joint, a second tube mother wire clamp fixed to the second fixing frame, a second screw rod and a sliding rod connected to the right fixing plate;

[0011] The second screw rod is connected with two second nuts through thread sleeves, and the right fixing plate is placed between the two second nuts, so that the distance between the sliding sleeve and the right fixing plate is adjustable;

[0012] The first busbar clamp and the second busbar clamp clamp the horizontal busbar;

[0013] It also includes a right angle plate, one end of which is overlapped with the right end of the right fixed plate and connected through a fastener, and the other end of the right angle plate is fixedly connected to the terminal plate of the right device.

[0014] Furthermore, the right angle plate includes a first angle plate and a second angle plate arranged at an angle; the first angle plate is attached to the right fixed plate, and the second angle plate is attached to the terminal plate of the right device.

[0015] Furthermore, the right angle plate includes a first angle plate attached to the right fixed plate and a vertical second angle plate, and the first angle plate and the terminal plate of the right device are respectively welded to both sides of the second angle plate.

[0016] Furthermore, the left device and the right device are respectively an isolating switch and a circuit breaker, or the left device and the right device are respectively a circuit breaker and an isolating switch.

[0017] Furthermore, the fasteners are a plurality of matching bolts and nuts.

[0018] In the above technical solution, the utility model has the following beneficial effects:

[0019] On the one hand, the left fixed plate connected to the terminal board of the left device and the first fixed frame of the fixed pipe mother are connected through an expansion joint, so that the height between the left fixed plate and the first fixed frame is adjustable; similarly, the height between the right fixed plate and the second fixed frame is adjustable.

[0020] On the other hand, one end of the first universal joint is sleeved on the first screw rod and placed between the two first nuts, so that the position of the first universal joint connected to the first fixed frame can be fine-tuned vertically; at the same time, the second screw rod is connected to two second nuts through threaded sleeves, and the right fixed plate is placed between the two second nuts, so that the distance between the sliding sleeve and the right fixed plate can be adjusted.

[0021] Both aspects have been achieved, and the cross-circuit fittings are compatible with equipment terminal boards of different heights on both sides.

[0022] Finally, the right angle plate is used to connect the gap between the right fixed plate and the right device. This gap is caused by the different angles of the terminal plates of the left and right devices. Different from the prior art, the right fixed plate is not directly fixed on the terminal plate of the right device, but the right angle plate is used to connect the two.

Similar expressions are only for the purpose of illustration, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention; in addition, the terms "one part", "two parts", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0034] like Figure 1-5 The cross-circuit fitting shown in the figure comprises, from left to right, a left fixing plate 1 connected to a terminal board of a left device, a first tube mother fitting component, a second tube mother fitting component, and a right fixing plate 8.

[0035] The first tube mother hardware component includes a first fixing frame 2 connected to the left fixing plate 1 through a first telescopic joint, a first tube mother wire clamp 3 fixed on the first fixing frame 2, a first screw rod 4 fixed on the top surface 1 of the left fixing plate, two first nuts 5 threadedly sleeved on the first screw rod 4, and a first universal joint 7 connecting the first screw rod 4 and the first fixing frame 2.

[0036] One end of the first universal joint 7 is freely sleeved on the first screw rod 4 and placed between the two first nuts 5; by adjusting the positions of the two first nuts 5 screwed on the first screw rod 4, the height of one end of the first universal joint 7 can be fine-tuned. Adjust the thermal expansion and contraction of the tube mother and fine-tune the position of the tube mother.

[0037] The second tube mother hardware component includes a second fixing frame 10 connected to the right fixing plate 8 through a second telescopic joint, a second tube mother wire clamp fixed to the second fixing frame 10, a second screw rod 11 connected to the right fixing plate 8, and a sliding rod 13;

[0038] The left end of the slide rod 13 is sleeved in the slide sleeve at the top end of the second screw rod 11, and the right end thereof is fixedly connected to the second fixing frame 10;

[0039] The second screw rod 11 is threadably sleeved with two second nuts 14, and the right fixing plate 8 is placed between the two second nuts 14, so that the distance between the sliding sleeve and the right fixing plate 8 is adjustable;

[0040] The first busbar clamp 3 and the second busbar clamp clamp the horizontal busbar;

[0041] The invention also includes a right angle plate 9, one end of which is overlapped with the right end of the right fixing plate 8 and connected by a fastener, and the other end of which is fixedly connected to the terminal plate of the right device. Different from the prior art, the right fixing plate is not directly fixed to the terminal plate of the right device, but is as follows: Figure 5 As shown, a right angle plate is used to achieve an angled connection between the two.

[0042] In addition to adjusting the angle of the terminal boards of the left and right devices, the right angle plate 9 can also adjust the height.

[0043] The first tube mother hardware component is the fixed end of the hardware, and the fixed end cannot move in the horizontal direction of the tube mother. The second tube mother hardware component is the sliding end of the hardware, and the sliding end slides through the action of the second telescopic joint. The height difference between the first fixing frame 2 and the second fixing frame is designed in advance to ensure the level of the tube mother, and the level of the tube mother is adjusted on site through the first screw and the second screw.

[0044] In general, if Figure 2 and Figure 5As shown, the right angle plate 9 is a flat plate structure. Because the terminal board of the device is generally placed horizontally or vertically, the right fixed plate 8 can be connected to the right angle plate 9. However, if the terminal board of the device involves multiple angles, the right angle plate 9 can include two plates with different planes, such as the following two right angle plates 9.

[0045] Preferably, Figure 3 As shown, a right angle plate 9 includes a first angle plate 91 and a second angle plate 92 arranged at an angle; the first angle plate 91 is attached to the right fixed plate 8, and the second angle plate 92 is attached to the terminal plate of the right device. The first angle plate 91 and the second angle plate 92 can be formed in one piece. In this way, the normal of the right fixed plate 8 is perpendicular to the ground, and the normal of the terminal plate of the right device is inclined to the ground and can also be connected by the right angle plate 9. The second angle plate 92 and the terminal plate of the right device can be connected using common fasteners such as bolts and nuts.

[0046] Preferably, Figure 4 As shown, another right angle plate 9 includes a first angle plate 91 attached to the right fixed plate 8 and a vertical second angle plate 92, and the first angle plate 91 and the terminal plate of the right device are respectively welded to both sides of the second angle plate 92. When the interval between the right fixed plate 8 and the terminal plate of the right device is relatively large, the existing terminal plate of the right device can be welded to the right angle plate 9. The second angle plate 92 plays the role of providing a welding operation surface and strengthening the edge strength of the right angle plate 9.

[0047] Preferably, the left device and the right device are respectively an isolating switch and a circuit breaker, or the left device and the right device are respectively a circuit breaker and an isolating switch.

[0048] Preferably, the fasteners are a plurality of matching bolts and nuts.

[0049] After the right end of the fixed plate 8 is overlapped, the mounting hole for the mounting bolt can be processed on site, or a waist-shaped hole for the mounting bolt can be directly opened on one end of the right angle plate 9, so that one end of the right angle plate 9 and the right end of the right fixed plate 8 are not completely overlapped, but are staggered and overlapped to achieve overlap of different angles between the two.

[0050] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
