Abstract

The utility model discloses a three -phase four -wire socket that experimental facilities was used, include: socket ontology 1 inlays on this socket ontology 1 and is equipped with 4 three -phase four -wire socket panel 2 that have A phase line terminal, B phase line terminal, C phase line terminal and ground wire terminal, its characterized in that, socket ontology 1 be the box body that the cross section is the cuboid form of rectangle, two external hitching leg holes 3 at this the box body back. Three -phase four -wire socket be fit for using when single supply socket gives the power cord length of two or above experimental facilities power supply and experimental facilities itself not enough simultaneously to can hang the experimental facilities nearby on the wall or other safe places, convenient to use.

Description

A kind of three-phase four-wire socket of experimental facilities

Technical field

The present invention relates to the field of experiment equipment of electric information laboratory, particularly to the three-phase four-wire socket of a kind of experimental facilities.

Background technology

At present, the laboratory of domestic many institution of higher learning is the most all after schoolhouse is built up, by relevant teacher or engineering, experiment skill Art personnel are arranged according to the teaching task that this special disciplines is undertaken and design, the electricity of some of them electrical experimental facility The most dilatory overlap joint in source, and be three-phase four-wire system, and the most only install the three-phase and four-line electricity of wall Supply socket, does not but have three-phase four-wire socket, be therefore frequently run onto install in advance the three-phase four-wire power socket number of wall not or The distance supply socket of person's experimental facilities putting position is farther out so that the problem such as the power line length of experimental facilities itself is inadequate；Even if having On wall, install the three-phase four-wire power got well enough, can use a bit according to experimental facilities quantity at that time than more elegant laboratory Socket, and the experimental facilities set up because of reasons such as teaching task changes later needs for overlapping temporary source, thus need Want a three-phase four-wire power socket to power to two or above experimental facilities simultaneously.

Summary of the invention

It is an object of the invention to the shortcoming overcoming prior art with not enough, it is provided that the three-phase four-wire socket of a kind of experimental facilities, Both the problem that experimental facilities power line length own is inadequate can have been solved, it is possible to solve two or above experimental facilities shares a three-phase The problem of four line supply sockets.

The purpose of the present invention is achieved through the following technical solutions: the three-phase four-wire socket of a kind of experimental facilities, including: socket is originally Body 1, this jack body 1 is embedded with 4 and has A phase terminal, B phase terminal, C phase terminal and the three of ground wire terminal Four line socket panel 2 mutually.

In the three-phase four-wire socket of described experimental facilities, 4 three-phase four-wire socket panels 2 are electrically being connected in parallel.

In the three-phase four-wire socket of described experimental facilities, external two hanging feet holes 3, its box body back side, it is possible to hang over experimental facilities On the wall nearby or place of other safety.

This utility model is suitable for single supply socket simultaneously to two or above experimental facilities is powered and the power supply of experimental facilities itself Use when line length is inadequate, preferably solve " single supply socket two for or how inadequate for, experimental facilities power line length own " Etc. problem.

This utility model can hang on experimental facilities wall nearby or the place of other safety, easy to use.

Accompanying drawing explanation

Fig. 1 is the overall schematic of the three-phase four-wire socket of a kind of experimental facilities；

Fig. 2 be the three-phase four-wire socket of a kind of experimental facilities electrically couple schematic diagram；

The most each parts labelling is as follows: 1 rectangular box, 2 three-phase four-wire socket panels, 3 external hanging feet holes, the box body back side, 4 socket panel installing holes.

Detailed description of the invention

Below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail, but embodiments of the present invention are not limited to this.

Referring to Fig. 1, Fig. 1 is the overall schematic of the three-phase four-wire socket of a kind of experimental facilities in the present embodiment.Fig. 1 institute The three-phase four-wire socket shown, connects as core with the power supply of experimental facilities, it is intended to solve single supply socket to two or above experiment Equipment is powered and the experimental facilities power line length problem such as not own.

Below in conjunction with Fig. 1 to Fig. 2, illustrate structure and the merit of the three-phase four-wire socket of a kind of experimental facilities in the present embodiment Energy.

Referring to Fig. 1, whole three-phase four-wire socket is made up of jack body 1 and 4 three-phase four-wire socket panels 2.

Referring to Fig. 2, jack body 1 is surrounded by the box body of the cuboid shape that cross section is rectangle, and wherein, front is provided with four Individual three-phase four-wire socket panel mounting hole 4, is embedded 1 three-phase four-wire socket panel the most at a glance in socket panel installing hole 4；The back of the body External two hanging feet holes 3, face.

Referring to Fig. 3 and combination sees Fig. 2, every three-phase four-wire socket panel 2 has A phase terminal, B phase terminal, C Phase terminal and ground wire terminal, 4 three-phase four-wire socket panels 2 are connected in parallel on A phase line, B phase line, C phase line and ground wire PE.

Above-described embodiment is the present invention preferably embodiment, but embodiments of the present invention being not restricted to the described embodiments, The change made under other any spirit without departing from the present invention and principle, modify, substitute, combine, simplify, all should For equivalence substitute mode, within being included in protection scope of the present invention.
