Abstract
The invention relates to a single-phase intelligent electric energy meter relay with a full-hard-pin structure, which is structurally optimized in the traditional magnetic latching relay, and all welding points with a PCB are connected by hard pins on the premise of ensuring all performances. The hard pin connection can accurately position the position of a hard pin, and the position of the hard pin can accurately position the position of a PCB pad hole. The design of the invention can accurately match the positions of the welding needle and the welding hole, and realizes the automatic installation of a production line. Meanwhile, the semi-circular shock absorption hard needle structure of the sampling needle is more reliable in connection, is not easy to damage, and prolongs the service life of the relay.
Description
Technical Field
The invention relates to a single-phase intelligent electric energy meter relay with a full-hard-pin structure, and belongs to the field of magnetic latching relays for intelligent electric energy meters.
Background
The magnetic latching relay uses permanent magnet or iron core with high remanence property to make the armature of relay still keep the state of last coil when it is electrified after the coil is cut off. The relay has the advantage that the conducting state of the relay can be changed in real time through the direction of the current driven by the coil.
The existing intelligent electric energy meter is complex in fixed installation, and is mostly connected with a PCB (printed circuit board) in a mode of combining a flexible wire and a terminal seat. The pencil is many, and installation operation space is narrow and small, is unfavorable for personnel's operation, very easily makes mistakes. The requirement on operators is extremely high during mass production, and therefore the single-phase intelligent electric energy meter relay with the full-hard-pin structure is provided.
Disclosure of Invention
The invention aims to provide a single-phase intelligent electric energy meter relay with a full-hard-pin structure, which is novel in design, facilitates installation of the relay by production personnel, and can realize automatic production, reduce repair and maintenance cost.
In order to solve the problems, the invention adopts the technical scheme that:
the single-phase intelligent electric energy meter relay with the full-hard-pin structure ensures all performances of the magnetic latching relay, and all connecting wires are changed into hard pins.
Furthermore, the number of the hard needles is 6, so that the on-off state control and detection of the relay can be met.
Furthermore, the connection mode of the hard needle and the metal part of the relay is riveting and welding.
Further, riveting can be earlier accurate fixed in hard needle position.
Furthermore, welding is a processing technology after riveting of the hard needle, and the hard needle connection is ensured to be more reliable
Furthermore, a semicircular arc structure is added on the hard needle, so that stress can be effectively released, and the influence of external impact on a welding position is reduced.

Fig. 1 is a schematic diagram of a single-phase intelligent electric energy meter relay with a full-hard-pin structure.
Detailed Description
To make the structure and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings.
As shown in fig. 1, the single-phase intelligent electric energy meter relay with the full-hard-pin structure comprises 6 hard pins.
Wherein the hard pins (1) and (2) are relay control pins, and the state of the relay is controlled by the flow direction of input current; the hard needle (3) is a relay live wire power supply needle and provides mains supply voltage for the electric energy meter; the hard needle (4) is a relay voltage detection needle and is used for detecting the opening and closing state of the relay; the hard pins (5) and (6) are relay current sampling pins and are used for detecting the current passing through the relay.
As shown in figure 1, the position of the hard needle is fixed, the relay can be easily installed on a PCB during production, and both manual installation and automatic board falling installation can improve the efficiency and reduce the manual installation errors.
The above description is of the principal features and advantages of the invention. The present invention is not limited to the above-described embodiments, which are merely illustrative of the principles of the present invention, but various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which is defined by the appended claims. The scope of the invention is defined by the appended claims and equivalents thereof.
