Users can determine current flow of the socket board by means of observing the length of a luminous post of the LED light post display (3), thereby preventing potential safety hazards due to over-heavy current of the socket board.

Description

A kind of terminal block that shows the magnitude of current

Technical field

The utility model relates to a kind of terminal block, especially a kind of terminal block that shows the magnitude of current.

Background technology

Most of in the market terminal blocks include shell and socket; Described socket is installed on the same horizontal plane, such structure causes inserting plug in the described socket and all places on same plane and cause the plug mutual extrusion, need guarantee to use a plurality of electrical appliances simultaneously by the area of plane that increases terminal block, and the electric wire of attachment plug be intertwined easily; Simultaneously, can not monitor terminal block electric current use amount device on the terminal block, be not easy to the user and understand terminal block whether use the magnitude of current to use excessive, be easy to generate hidden danger.

A kind of is the fixed terminal block of a kind of disjunctor of CN 2495040Y in China's mandate and notification number; The fixed terminal block of described disjunctor by plastic casing and metallic interconnect, binding post, plug in folder etc. and form; In the described plastic casing metal assembly is arranged, described metal assembly is fastened on the plastic insulation plate, and being that both are firm connects into an assembly board; Described assembly board combines with shell again, makes the overall structure of terminal block firmly be not easy to become flexible; The jack of described terminal block all is arranged on the same plane, causes the plug mutual extrusion easily, and the area that needs to increase terminal block guarantees that a plurality of plugs can insert simultaneously, and the electric wire of attachment plug twines generation hidden danger; Simultaneously, do not have the device of monitoring current use amount on the described terminal block, can't show the magnitude of current of terminal block in real time.

The utility model content

In order to solve the problem that the used magnitude of current was placed and can't be shown on the same plane of most of terminal block sockets, the utility model provides a kind of socket to separate both sides and has placed, and can be the terminal block that the user provides the real-time current use amount.

In order to reach a kind of terminal block that shows power consumption that above-mentioned technical goal the utility model provides, include shell and some sockets, described shell is that the cross section is trapezoidal strip structure, described socket divides two groups of both sides that are installed in described shell respectively; Trapezium structure top at described shell is provided with the LED bar graphic display; Described LED bar graphic display links to each other with setting ammeter in the enclosure.

Described socket separates both sides to be installed, and being convenient to the user can insert plug from two different angles, and but the electric wire of attachment plug is not easy to twine, and also gives electrical appliance more placing direction; Simultaneously, trapezoidal column structure can be saved the space, can guarantee that when need not to increase the terminal block area of plane a plurality of electrical appliances can use simultaneously; In addition, described ammeter is set on described shell can shows the magnitude of current that inserts this terminal block electrical appliance in real time, and use the LED bar graphic display to send visible light and show the real-time current amount, be convenient to the user from the remote magnitude of current that uses of observing, more obvious than the ammeter demonstration of common quantity and total indicator reading.

As further prioritization scheme, described shell is made by plastic material; Plastic material is placed the circuit electric leakage in the shell or is produced static as the insulation physical efficiency user is produced hidden danger.

As further prioritization scheme, the both sides height of described shell is identical, and the angle of both sides is not less than 60 °; The both sides height is identical has guaranteed that whole casing square is placed on the balance on the horizontal plane; Described angle can reduce terminal block and put in the plane space, has guaranteed that simultaneously different electrical appliances can use simultaneously.

As further prioritization scheme, the socket of telling is a Three-hole socket for one group, and another group is the diplopore socket, is installed in the both sides of described shell respectively; Described socket separately two groups place respectively and can be convenient to the user and plug is separated both sides insert in the different sockets, give space enough between the plug, prevent the plug mutual extrusion and can't put into socket, and prevented that also the electric wire that links to each other with plug from producing winding hidden danger takes place.

This realization is novel to have such beneficial effect; Be that socket branch both sides are arranged on the utilization rate that has improved socket on the shell, prevented that plug from can't use simultaneously owing to pressurizeing mutually, also prevented that the electric wire that links to each other with plug from winding taking place produce hidden danger simultaneously; Simultaneously, the ammeter of band LED bar graphic display allows the user can be from the magnitude of current of remote this terminal block of monitoring in real time, the purpose of arriving reminding user's electrical energy saving.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described further.

As shown in Figure 1, terminal block described in the utility model includes the cross section and is trapezoidal strip shell 1; And the angle on described shell 1 both sides is not less than 60 °, and both sides are contour and be provided with two groups of sockets 2, and is provided with a LED bar graphic display 3 in the trapezoidal top of shell 1 side; Described LED bar graphic display 3 links to each other with an ammeter, and its described ammeter is arranged in the shell 1 and connects with the terminal block internal circuit.

As described in Figure 2, socket 2 is divided into two groups of both sides that are installed in shell 1 respectively, is provided with Three-hole socket 2 in a side of shell 1; As shown in Figure 3, the opposite side at shell 1 is provided with diplopore socket 2.

The user is when using terminal block; The user can select to insert different sockets 2 according to the different size of plug, and simultaneously, the ammeter in the terminal block can be monitored the power consumption of whole terminal block in real time; Digital to analog converter in the described ammeter converts the simulation model of the electric current collected to digital model; Also be provided with a single-chip microcomputer in the described ammeter and be used to receive the good digital signal of conversion, and one group of contrast signal is compared; Single-chip microcomputer shows by LED bar graphic display 3 comparative result the electric current use amount of terminal block with the luminous length of LED light beam.

Specifically, the electrical appliance that connect on terminal block increases, and when the magnitude of current increased, the magnitude of current in the circuit increased, and the reading of the magnitude of current converts the discernible digital signal of single-chip microcomputer to by analog to digital converter, with described single-chip microcomputer in contrast signal compare; The result of contrast adjusts the light beam of LED bar graphic display 3 again by single-chip microcomputer, make the LED light beam elongated, reminds the increase of user's ammeter use amount.

When the magnitude of current that uses on the terminal block was excessive, the brightness of LED bar graphic display 3 was shown to the brightest, reminded the magnitude of current on user's terminal block excessive, needed to reduce the electrical appliance on this terminal block, guaranteed not because the excessive generation potential safety hazard of the magnitude of current. ?
