Abstract

A novel bus-bar clamp device belongs to power transmission and distribution devices and comprises a bus-bar clamp, a regulation module and a mounting bracket, wherein the bus-bar clamp includes an upper seat and a lower seat, a bus-bar cavity for clamping bus bars is formed between the upper seat and the lower seat, the regulation module is arranged in the bus-bar cavity between the upper seat and the lower seat to regulate specifications of bus bars, the mounting bracket is connected with the frame of a distribution cabinet, and the bus-bar clamp is mounted on the mounting bracket. The novel bus-bar clamp device has the advantages of enabling the bus-bar clamp to be adapted to bus bars with different specifications, greatly improving the commonality of products, modulization-designing the bus-bar clamp, assembling the bus-bar clamp according to requirements of different occasions, and reducing manufacturing costs.

Description

Novel bus-bar clamp device

Technical field

The utility model belongs to the low pressure equipment for power transmission and distribution, particularly a kind of novel bus-bar clamp device of low-voltage distribution cabinet.

Background technology

The bus-bar clamp device of conventional low power distribution cabinet, volume are big, installation is inconvenient, intensity is not high, when particularly the bus of different size is changed mutually, need the bus clip integral replacing, and this has also caused the great wasting of resources.In addition, angle from the mode of connection, mainly contain two kinds of modes of connection of three-phase and four-line and phase three-wire three in the market, for existing traditional bus device, because the integrated design of bus clip can not form independently installed module, has caused the increase of manufacturing cost, and also bring the shortcoming of selecting inconvenience for use, can not satisfy the needs of modern industry design simultaneously.

Summary of the invention

The purpose of this utility model is the design deficiency at prior art, and a kind of novel bus-bar clamp device is provided, and it can adapt to different specifications and apart the bus and the bus connected mode of the different numbers of phases, highly versatile, low cost of manufacture.

The purpose of this utility model reaches like this, a kind of novel bus-bar clamp device, comprise bus clip, adjustment module 3 and mounting bracket 4, described bus clip is made of the seat of honour 2 and following 1, is formed with the bus chamber that is used for clamping bus 5 between the seat of honour 2 and following 1; Described adjustment module 3 places in the bus chamber between the seat of honour 2 and following 1, is used to regulate bus specification; Described mounting bracket 4 is connected with distributing cabinet frame, is fixed with described bus clip on it.

It is the bus chamber that centre described in the utility model following 1 is formed with " U " shape cavity, is formed with a pair of dovetail groove 12 on the sidewall in described bus chamber.

Adjustment module described in the utility model 3 both sides are formed with a pair of pin 31 that matches with dovetail groove 12 of being used for.

Be provided with the groove 32 that is used to install bus 5 in the middle of the upper surface of adjustment module 3 described in the utility model.

Following 1 bottom described in the utility model is provided with fixing feet 11.

Mounting bracket 4 described in the utility model is provided with and is used for the installing hole 41 that matches with fixing feet 11.

The utility model is because after adopting said structure, one of advantage that has, with respect to traditional bus clip, the utility model has increased by one and has been used for the adjustment module that cooperates with bus, can improve the versatility of product greatly so that bus clip can adapt to the bus of different size by this adjustment module; Advantage two, with the bus clip modularized design, according to the needs of different occasions, come the composite assembly bus clip, reduced manufacturing cost.

Embodiment

See also Fig. 1 and in conjunction with Fig. 3, Fig. 4 and Fig. 5, the novel bus-bar clamp device of the utility model comprises bus clip, adjustment module 3 and mounting bracket 4, described bus clip is made of with following 1 the seat of honour 2, between the seat of honour 2 and following 1, be formed with the bus chamber that is used for clamping bus 5, described adjustment module 3 places in the bus chamber between the seat of honour 2 and following 1, with the seat of honour 2, following 1 and adjustment module 3 three's assembly units and by acting in conjunction after the screw of both sides in bus 5, use making bus 5 firm must being held in the bus clip.And screw inserts in the screw of mounting bracket 4 as shown in Figure 3 after passing whole bus clip, and bus clip is fixed on the mounting bracket 4.Simultaneously for bus clip is fixed on the mounting bracket 4 better, be provided with a pair of fixing feet 11 in described following 1 bottom, correspondingly, on described mounting bracket 4, be provided with a pair of installing hole 41, described fixing feet 11 is inserted in the corresponding installing hole 14, makes bus clip to be installed on well on the mounting bracket 4.

Please continue to consult Fig. 1 and in conjunction with Fig. 6, Fig. 7 and Fig. 8, it is the bus chamber that centre described in the utility model following 1 is formed with " U " shape cavity, on the sidewall in described bus chamber, be formed with a pair of dovetail groove 12, correspondingly, be formed with a pair of pin 31 that matches with dovetail groove 12 of being used in described adjustment module 3 both sides, cooperating of pin 31 by dovetail groove 12 and adjustment module 3, make adjustment module 3 better must be fixed in the bus clip, when needs are regulated the thickness of bus 5, bus 5 can increase or reduce the quantity of adjustment module 3, till can be clamped in the bus chamber securely.
