technical field

The utility model relates to an auxiliary facility for testing a watt-hour meter, in particular to a watt-hour meter test connection assembly for connecting a measurement and control station and a watt-hour meter.

Background technique

When testing the watt-hour meter, one end of the used connecting wire has a connecting plug to connect with the measurement and control console, and the other end is a plurality of clips, which are respectively connected to the corresponding terminals of the watt-hour meter. The connection terminal of the watt-hour meter is generally a screw, the contact area is very small, the clip is not firm after being clamped, and it is easy to fall off; there is also a small connection piece on the connection terminal, because the connection piece is very short, the contact area between the clip and the connection piece Small, the clip is not firm after being clamped, and it is easy to fall off. The voltage under the clip is 380V, and the clip falls on these devices, which brings certain safety hazards to the testers; on the other hand, the measurement and control console connected to the other end of the clip is a 24V weak current device, which is easy to break down the device; Because individual clips fall off, it is necessary to stop the test and fix the clips before retesting, which is a waste of time.

In order to solve the above-mentioned problems, people have been looking for an ideal technical solution to seek a watt-hour meter test connection assembly that is firmly connected during testing, is convenient to use, and saves time and effort.

Utility model content

The purpose of the utility model is to aim at the deficiencies of the prior art, and provide a watt-hour meter test connection assembly which is firmly connected, convenient to use and saves time and effort.

In order to achieve the above object, the technical solution adopted by the utility model is: a watt-hour meter test connection assembly, including a connection terminal and a connection wire, the connection terminal includes a base plate and a connection socket arranged on the base plate, the The wiring socket is in the shape of a tube, and a connection jack is provided on the base plate for connecting the watt-hour meter; one end of the connection line is provided with a measurement and control plug for connection to the measurement and control console, and the other end is divided into multiple signal lines, each of which is The outer end of the signal line is provided with pins, the pins are arranged corresponding to the wiring socket, the side wall of the pin is provided with a radially outward elastic protrusion or the inner wall of the wiring socket is provided with a radial direction Elastic protrusions inside.

Based on the above, an insulating sheath is provided on the pin outer cover, and the inner diameter of the insulating sheath is not smaller than the outer diameter of the connection socket.

Based on the above, the colors of the outer insulating layers of different signal lines are different.

Based on the above, the color of the insulating sheath is the same as that of the outer insulating layer corresponding to the signal line.

Based on the above, the connection terminal is a red copper connection terminal.

Compared with the prior art, the utility model has substantive features and progress. Specifically, the utility model uses pins and wiring sockets to connect the measurement and control console and the watt-hour meter, which is convenient to use. The pins or the wiring sockets are provided with elastic The protrusions make the connection between the two firm and not easy to fall off. Furthermore, the outer side of the contact pin is provided with an insulating sheath, which is less prone to short-circuit accidents and has high safety. Furthermore, the outer insulating layers of the signal lines are of different colors, which are easy to distinguish, convenient to connect, and save time and effort. The watt-hour meter test connection assembly has the advantages of being easy to use, not easy to fall off, and safe and reliable.

detailed description

The technical solutions of the present invention will be further described in detail through specific implementation methods below.

As shown in Fig. 1, a kind of watt-hour meter test connection assembly comprises terminal block and connecting line 4, and described terminal block comprises base plate 1 and the connection socket 2 that is arranged on the base plate, and described connection socket is tubular, so The bottom sheet 1 is also provided with a connection jack 3 for connecting with the watt-hour meter, and the connecting terminal is fixed on the watt-hour meter through the bottom sheet 1 . One end of the connection line 4 is provided with a measurement and control plug 5 for connecting to the measurement and control console, and the other end is divided into a plurality of signal lines 6 for respectively connecting the connection terminals, and the outer end of each of the signal lines 6 is provided with a pin 7 , the pins 7 are arranged correspondingly to the wiring socket 2 , and the side walls of the pins 7 are provided with radially outward elastic protrusions 8 . When the two are connected, the contact pin 7 is inserted into the connection socket 2, and the inner wall of the connection socket 2 is provided with a radially inward elastic protrusion 9, so that the contact force between the contact pin 7 and the connection socket 2 Increased, the connection is firm, the pin 7 is not easy to fall off, and the safety is high. In other embodiments, radially inward elastic protrusions may also be provided on the inner wall of the wiring socket, so that the contact force between the pins and the wiring socket is increased and the connection is firm.

The test terminals of the watt-hour meter are relatively close to each other. In order to prevent short circuit, the associated pins 7 are covered with an insulating sheath 8 , and the inner diameter of the insulating sheath 8 is larger than the outer diameter of the connecting socket 2 .

For convenience of distinction and connection, the outer insulating layers of different signal lines 6 have different colors.

For convenience of distinction, the color of the insulating sheath 8 is the same as that of the outer insulating layer corresponding to the signal line 6 .

In order to enhance the electrical conductivity of the utility model, the connecting terminal is a red copper connecting terminal.
