The installation frame adopts the conductive elastic sheet 11, the electrified connection of the electric power instrument 100 at the position 10 can be completed through the plugging of the conductive elastic sheet 11 and the wiring port 101, and due to the abutting action of the conductive elastic sheet 11, the good and reliable conductive contact between the conductive elastic sheet 11 and the wiring port 101 can be ensured, the workload of operators can be reduced, the efficiency of the ageing procedure of the electric power instrument 100 can be improved, and the production speed can be accelerated.

In other embodiments, when the connection port 101 is plugged with the conductive elastic sheet 11, the tightening piece 112 can elastically deform toward the connection piece 111 to generate elastic force.

Referring to fig. 5 and 7, the abutting piece 112 includes a guiding portion 1121, the guiding portion 1121 is connected to the connecting piece 111 and is inclined with respect to the connecting piece 111, and the guiding portion 1121 is used for providing guiding function for plugging the connection port 101 with the conductive elastic piece 11. Specifically, when the top end of the conductive spring 11 just enters the wiring port 101, the inner wall of the wiring port 101 contacts with the guide portion 1121, and during the continuous insertion process, the inner wall of the wiring port 101 slides along the side wall of the guide portion 1121, during which the connecting piece 111 and/or the abutting piece 112 are deformed (e.g. elastically deformed) by pressing the guide portion 1121, and after the insertion is completed, the abutting piece 112 can contact with the inner wall of the wiring port. In this embodiment, in the process that the inner wall of the connection port 101 presses the guiding portion 1121, the connecting piece 111 and/or the abutting piece 112 elastically deforms, so that the conductive elastic piece 11 has elastic force, and after the conductive elastic piece 11 is plugged in place, the abutting piece 112 can abut against the inner wall of the connection port 101 under the elastic force of the conductive elastic piece 11.

Further, the abutting piece 112 further includes a contact portion 1122, the contact portion 1122 is connected to an end of the guiding portion 1121 away from the connecting piece 111, and the contact portion 1122 is used for electrically contacting with an inner wall of the connection port 101. Optionally, the contact portion 1122 has an arc surface for contacting the inner wall of the connection port 101, so as to avoid a sharp point at the contact position of the abutting piece 112 with the connection port 101, and prevent the contact portion 1122 from scratching the inner wall of the connection port 101 during the process of plugging the power meter 100.

The mounting piece 113 and the carrier plate 12 have larger contact area, so that the mounting stability is ensured. Furthermore, the fastener 13 is also used to connect the wires in the burn-in circuit to connect the conductive dome 11 into the burn-in circuit.

Specifically, referring to fig. 7, the fastener 13 includes a fastening bolt 131 and a lock nut 132, and the fastening bolt 131 passes through the mounting plate 113 and the carrier plate 12 downward in the Z direction and is screwed with the lock nut 132 to fix the conductive elastic sheet 11. When connecting the wires, the copper lugs at the ends of the wires can be penetrated at the lower ends of the fastening bolts 131, and then the wire connecting nuts are screwed on the fastening bolts 131, so that the copper lugs at the ends of the wires are clamped between the locking nuts 132 and the wire connecting nuts.

Alternatively, referring to fig. 7, a mounting groove 121 is provided on the carrier plate 12, a mounting piece 113 is fixed to the bottom of the mounting groove 121, and one end of the connecting piece 111 connected to the abutting piece 112 protrudes out of the mounting groove 121. On the one hand, the lower end of the connecting piece 111 extends to the bottom of the mounting groove 121, so that the length of the connecting piece 111 can be increased, the connecting piece 111 is easier to elastically deform, and excessive labor is avoided when the electric instrument 100 is plugged in; on the other hand, the head of the fastening bolt 131 may be hidden in the mounting groove 121, so that the bottom of the electric power meter 100 cannot contact with the carrier plate 12 due to interference between the head of the fastening bolt 131 and the wiring port 101 is avoided.

Optionally, in this embodiment, the conductive spring 11 is integrally bent and formed, so that the manufacturing efficiency is high and the strength can be ensured. Further, the conductive spring piece 11 is formed by bending a copper sheet, so that the copper sheet has excellent conductivity, and good conductivity between the conductive spring piece 11 and the wiring port 101 is ensured.

Further, the first limiting plate 14 is used for being connected with the frame assembly 2 (can be connected with the frame assembly 2 through screws), and plays a role in fixing the whole installation assembly 1. The dimension of the first limiting plate 14 along the Z direction is larger, so that a sufficient connection area exists between the first limiting plate 14 and the frame assembly 2. The size of the second limiting plate 15 along the Z direction is relatively smaller, and the upper end of the second limiting plate slightly exceeds the upper surface of the carrier plate 12 by a certain distance, for example, 1cm, so that the second limiting plate 15 can play a role in limiting the electric power instrument 100, and a sufficient space is provided above the second limiting plate 15, so that the electric power instrument 100 can be smoothly placed on the position meter 10 between the first limiting plate 14 and the second limiting plate 15.

One end of the wire is connected to the fastener 13, and the other end is led out through the port position of the wiring channel 16. The wires can be hidden through the wiring channel 16, so that the wires are prevented from being disordered.

Specifically, a bottom plate 17 is disposed at a bottom of the carrier plate 12 at intervals, two sides of the bottom plate 17 along the Y direction are respectively connected to the first limiting plate 14 and the second limiting plate 15, and the bottom plate 17, the first limiting plate 14, the second limiting plate 15 and the carrier plate 12 enclose to form the routing channel 16.

The material of the carrier plate 12 is an insulating material, so that the electrical connection between the wiring port 101 and the conductive spring plate 11 is not disturbed. Since a large amount of heat is generated during the aging process of the electric power meter 100, the temperature resistance value of the insulating material needs to be greater than the set temperature threshold value, so as to avoid the damage of deformation, melting, even burning, etc. of the carrier plate 12 caused by the high temperature. The temperature threshold is the highest temperature that can be reached during the aging test of the electric power instrument, in this embodiment, the electric power instrument is taken as a three-phase guide rail meter, and the highest temperature that can be reached during the aging test of the three-phase guide rail meter is 65±3 ℃, that is, the temperature threshold range is 65±3 ℃. Illustratively, the carrier plate 12 is fabricated using high temperature resistant wood.

Further, since the electric power meter 100 in the embodiment is in contact with the first limiting plate 14 and the second limiting plate 15, and the wires generate heat in the routing channel 16, the whole installation assembly 1 is made of high-temperature-resistant wood, so that the installation assembly 1 is prevented from being adversely affected by high temperature.

Specifically, as shown in fig. 2, M mounting assemblies 1 are disposed on opposite sides of the rack assembly 2 along the Y direction, the M mounting assemblies 1 on each side are arranged along the Z direction, and n placement bits 10 are distributed on each mounting assembly 1 along the X direction, so that one side of the rack assembly 2 has m×n placement bits 10 distributed in an array, and the total number of M. Furthermore, since the two sides of the frame assembly 2 are provided with M epitope locations 10, the capacity is further enlarged.

Illustratively, the housing assembly 2 has a dimension in the X-direction of 1600mm and a dimension in the Z-direction of 1560mm.
