DETAILED DESCRIPTION

[0024] This specific embodiment is a multi-parameter integrated measuring instrument, and its structural diagram is as follows Figures 1-6As shown, the tester 1 includes a fixed terminal 2, a modular terminal 3 is provided on one side of the fixed terminal 2, a wiring slot 4 is provided on the side wall of the modular terminal 3, a locking piece 5 is rotatably connected to the side wall of the modular terminal 3, a snap-on assembly is provided between the modular terminal 3 and the fixed terminal 2, a conducting piece 9 is provided between the modular terminal 3 and the fixed terminal 2, the conducting piece 9 is U-shaped, and a through slot 13 is provided on the side wall of the conducting piece 9.

[0025] Among them, the tester 1 can adopt the ADW2xx series rail-type multi-circuit circuit meter, which can directly or indirectly measure voltage, current, power, power factor, phase angle and other parameters. The instrument is an existing technology, and its internal structure and principle will not be described in detail in this scheme. This scheme mainly optimizes the wiring terminals of the instrument.

[0026] like Figure 3 and Figure 4 As shown, the snap-on assembly includes rectangular grooves 6 respectively opened on the side walls of the fixed terminal 2 and the modular terminal 3, the side walls of the rectangular grooves 6 are fixedly connected to two blocks 7, and the rear side walls of the modular terminal 3 are fixedly connected to a diamond ring 8, which is adapted to the rectangular grooves 6.

[0027] Among them, the diamond ring 8 is made of flexible materials, such as metal elastic sheets, plastic elastic sheets, etc., which can quickly rebound and reset after being squeezed. When the diamond ring 8 is forced into the inside of the rectangular groove 6, it quickly expands and is limited by the block 7. Since the modular terminal 3 is not heavy, this structure can achieve the purpose of stable connection.

[0028] like Figure 4 As shown, the blocks 7 are symmetrically distributed on both sides, and are all arc-shaped structures. The arc-shaped arrangement facilitates the insertion or removal of the diamond ring 8, so that the diamond ring 8 is subjected to balanced force and has better stability.

[0029] like Figure 5 As shown, the conductive piece 9 is located on one side of the through-slot 13 and is fixedly connected to an insulating layer 10. The exposed sidewalls of the conductive piece 9 are all wrapped with the insulating layer 10, which can effectively reduce the safety of live working and prevent short circuits during use. In addition, the conductive piece 9 is made of conductive materials such as copper and aluminum, which has a certain degree of flexibility and can be bent arbitrarily during assembly.

[0030] like Figure 4 and Figure 5 As shown, a first tooth block 11 is fixedly connected to the side wall of the conducting piece 9 , and a second tooth block 12 is fixedly connected to the side wall of the wiring slot 4 . The first tooth block 11 is adapted to the second tooth block 12 .

[0031] Specifically, when the conducting piece 9 is assembled, the first tooth block 11 and the second tooth block 12 are engaged, and combined with the squeezing force of the locking piece 5, the conducting piece 9 is in a clamped state and will not be easily pulled out or fall off, ensuring stable conduction on the same terminal.

[0032] like Figure 4 As shown, the locking member 5 is fixedly connected to a plurality of protrusions 14 on the side wall close to the wiring slot 4. The protrusions 14 can increase the friction between the wires and further improve the stability of the wire connection.

[0033] Working principle: When it is necessary to connect multiple wires of the same voltage and current to the tester 1, select an appropriate number of modular terminals 3 according to the number of wires, first insert one end of the conductive piece 9 into the fixed terminal 2, then connect a wire to the fixed terminal 2 and fix it, and squeeze the conductive piece 9 at the same time, then install the modular terminal 3 on the corresponding position of the fixed terminal 2, align the diamond ring 8 on the modular terminal 3 with the rectangular groove 6 and insert it, and press it slightly. The diamond ring 8 contacts the stopper 7 and is deformed by the force, so that the width of the diamond ring 8 becomes narrower, so that it enters the rectangular groove 6, and then the modular terminal 3 is against the fixed terminal 2, and the force on the diamond ring 8 disappears and resets. The stopper 7 is used to block the diamond ring 8 to prevent the modular terminal 3 from detaching, which plays a role of convenient fixation. Then the other end of the conductive piece 9 and the wire are inserted into the modular terminal 3, and fixed with the locking piece 5, so that the terminals at the same position are in a connected state.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
