Abstract

The utility model relates to a slide terminal box belonging to the electrical connection device technical field. The terminal box comprises a case body, wherein, the cross section of the case body is in the shape of U; the inside of the case body is fixed with an insulated bracket; the insulated bracket is provided with an open line bank groove facing upwards towards a busbar line bank; the inside of the line bank groove is provided with a metal line bank with the shape matched with that of the line bank groove; an elastic part is arranged between the lower part of the metal line bank and the bottom of the line bank groove; both sides of the upper part of the case body are provided with two rows of inward horizontal roller wheels matched with the corresponding guide track of a bus duct; moreover, a conducting wire with one end in electrical connection with the metal line bank is led out from the perforation arranged on the case body. Therefore, under the action of the elastic part, the metal line bank and the bus line bank maintains reliable electric contact; meanwhile, the two rows of roller wheels ensure that the terminal box can move freely along the guide track of the bus duct under the action of pulling force, thereby meeting the use requirements of a slide electrical apparatus used in a product line.

Description

The slip terminal box

Technical field

The utility model relates to a kind of termination, and especially a kind of architecture advances of the terminal box of sliding belongs to the arrangements of electric connection technical field.

Background technology

Understand according to the applicant, the consuming device that many production lines are equipped with needs displacement in use.In the past, the lead that this type of consuming device is often very long in tow was to satisfy the needs of displacement power supply.This mode of dragging line to power not only hinders the operation of consuming device, makes the operator feel burdensome, and causes accident, safety inadequately easily.For this reason, people have designed the slip terminal box, utilize the mode of similar electric car power supply to satisfy the needs that the consuming device displacement is powered on the production line.Yet existing slip junction box structure is unreasonable, therefore exists to electrically contact reliable inadequately, the nimble inadequately problem of sliding.

The utility model content

The purpose of this utility model is: at the problem that above prior art exists, proposes a kind ofly can electrically contact under the reliable premise the nimble slip terminal box of sliding in assurance.

In order to reach above purpose, slip terminal box of the present utility model comprises box body, described box body cross section is the U type, described box body internal fixation insulating support, described insulating support is shaped on upwards recessed facing to bus row's unlimited bank, the metal bank of assigning shape to coincide with it during described bank is recessed, the bottom of described metal bank and bank are recessed to be equipped with elastic component between low, the inside horizontal roller of two rows that corresponding guide rail with bus duct matches is equipped with in both sides, described box body top, and the lead that an end is electrically connected with the metal bank is drawn in the perforation on the described box body.

Like this, under the effect of elastic component, can guarantee that metal bank and bus row remains reliable electrical contact, and two row's rollers can guarantee that terminal box is when receiving drag force, guide rail along bus duct is shifted freely, thereby satisfies the instructions for use of slip consuming device on the production line.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the structural representation of a preferred embodiment of the utility model.

Fig. 2 is the end view of Fig. 1.

Embodiment

Embodiment one

The slip terminal box of present embodiment as depicted in figs. 1 and 2, box body 5 is made by the steel plate bending, the cross section is the U type.The perforation wing plate to the both sides inclination is extended at two ends, box body 5 bottom respectively, and being used for bolt is hauling rope, and being convenient to draw box body or caring for need be with the small articles of terminal box slip.Bottom fixed plastics insulating support 7 in the box body 5.This insulating support top extends upward three rows and is shaped on the upright row who upwards faces corresponding bus row 3.It is recessed to have two adjacent rectangle cross section banks that open wide on each upright row up, the square-section copper bank 4 of assigning shape to coincide with it during each bank is recessed.Welding lead 8 in the middle of the bottom of each metal bank, this lead are drawn external consuming device power supply after passing the perforation of the center of spring 6 and insulating support and box body bottom.Spring 6 be contained in copper bank and bank recessed low between, copper bank 4 is remained to the trend that rises.The inside horizontal bearing roller 1 of two rows that matches with bus duct 2 corresponding guide rails is equipped with in both sides, box body top.

The plastic material of bus duct 2 usefulness hollows is made, and is not only light and handy but also have enough intensity.As shown in Figure 2, its both sides, top are shaped on depression, form guide rail along its length, the bottom is shaped on three emissions grooves down along its length, the two side of every emissions groove becomes dentation, thereby make every emissions groove become three layers of slot, insert fixing transmission of electricity bus row 3 among Fig. 2 in the superiors' slot, also the bus socket can be located in the slot of lower floor as required.Each bus row's lower surface contacts with the upper surface of corresponding copper bank 4, thereby electric energy transmitting is arrived copper bank 4.

Facts have proved, under spring action, metal bank and bus row remain reliable electrical contact, and roller is along the rolling of guide rail, can guarantee that terminal box is when receiving drag force, guide rail along bus duct easily is shifted, thus the slip terminal box of present embodiment very the occasion of needs slip power supply such as suitable various production lines adopt.

In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
