Description

TECHNICAL FIELD

[0001] The utility model relates to electronic instrument technical field, specifically, relate to a terminal seat subassembly and electric energy meter. BACKGROUND

[0002] At present, electric energy meter is used for electric power and quantity measurement instrument equipment, and each electric energy meter is configured with a terminal seat. The electric energy meter is divided into built-in meter and external meter according to the condition that load switch is in meter or outside meter. The built-in meter internally has a relay, and the current sampling signal is realized through the manganese copper on the meter relay. The internal meter does not equip the relay, and the sampling signal is directly sampled through the manganese copper. The sampling signal of the manganese copper output of the built-in meter and the external meter is connected with the PCB (Printed Circuit Board) by the mode of hard needle. Therefore, in order to ensure that the built-in meter and the external meter can use the same PCB layout, it is necessary to ensure that the manganese copper hard needle position of the built-in meter and the external meter is consistent. The current internal and external compatible structure mainly considers the convenience of the relay, so the sampling needle adopts the vertical arrangement mode, which leads to that the manganese copper cost of the external meter is very high. At the same time, the vertical arrangement of the sampling needle also brings certain difficulty to the layout of the PCB hardware.

[0003] Therefore, how to design a terminal seat subassembly which can keep the consistency of the sampling needle position of the built-in meter and the external meter, effectively reduce the manganese copper cost of the external meter and simplify the PCB layout becomes the problem to be solved at present. SUMMARY

In view of the high cost of the existing external manganese copper, the spatial layout of the relay relative to the terminal block is changed, the position of the relay relative to the terminal block is appropriately moved to the right from directly above, and the arrangement direction of the voltage sampling pin and the current sampling pin is adjusted from the original vertical arrangement to a horizontal arrangement, thereby simplifying the manganese copper structure, reducing the amount of manganese copper material, and achieving the purpose of reducing cost.

[0104] 2. By changing the arrangement direction of the voltage sampling pin and the current sampling pin, the influence of the voltage sampling pin and the current sampling pin on the PCB layout is reduced, the utilization rate of the PCB is improved, and the layout design of the hardware PCB is more convenient.

[0105] The beneficial effects of the present application are as follows:

[0106] 1. The problem of high cost of external meter manganese copper caused by vertical arrangement of sampling needles relative to terminal block is solved: the current internal and external compatible structure is mainly for the convenience of the relay, which makes the arrangement of the live sampling needle adopt a vertical arrangement relative to the terminal block. However, this arrangement results in high cost of manganese copper required for hard connection of external meter.

[0107] 2. The problem of difficult PCB layout caused by vertical arrangement of sampling needles is solved: the current live sampling needle adopts a vertical arrangement, which occupies a lot of PCB space and brings difficulties to the layout of the PCB.

[0108] Through the above two improvements, the cost of external manganese copper can be effectively reduced without increasing the cost of the relay, and the most effective layout space is provided for the layout of the PCB.
