[0020] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0022] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0023] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0025] See also Figures 1 to 4 As shown, the utility model provides a plug-in relay, including a relay body 1, a plug-in piece 3 connected to the lead end of the relay body 1 for inserting into the chassis 2 of the electric meter, a protrusion 4 arranged on the plug-in piece 3 and abutting against the chassis 2 of the electric meter, and a cotter pin 5 cooperating with the protrusion 4 to fix the relay body 1 to the chassis 2 of the electric meter.

[0026] Each of the plug-in relays includes two inserts 3 arranged in parallel and at intervals, the inserts 3 including a fixing portion 31 and a plate-shaped inserting portion 32 integrally formed with the fixing portion 31, the fixing portion 31 is connected to the relay body 1, and the inserting portion 32 is used to be inserted into the meter chassis 2. The fixing portion 31 of the insert 3 is fixed to the relay body 1 by welding.

[0027] Specifically, the insertion portion 32 includes a first surface 321 , a second surface 322 disposed opposite to the first surface 321 , and a third surface 323 connecting the first surface 321 and the second surface 322 .

[0028] There are two protrusions 4, and the two protrusions 4 are respectively arranged in parallel on the first surface 321 and the second surface 322. Specifically, the two protrusions 4 are located at one end of the insertion portion 32 adjacent to the fixing portion 31, and are respectively arranged at the left and right ends along the width direction of the first surface 321 and the second surface 322. A plurality of grooves 3231 are formed on the third surface 323, and the grooves 3231 are located on the side of the protrusion 4 away from the fixing portion 31.

[0029] The plug 3 is also provided with a through hole 6 penetrating the first surface 321 and the second surface 322. The through hole 6 is located below the protrusion 4 and is used for inserting the split pin 5. After the plug is inserted into the meter chassis, the protrusion and the split pin are clamped on the upper and lower sides of the meter chassis. The protrusion abuts against the meter chassis to position the plug to prevent the plug from moving randomly. On this basis, the split pin is inserted and clamped with the meter chassis to fix the relay body and the meter chassis.

[0030] In the specific implementation, the A-phase relay and the B-phase relay are installed in the chassis of the meter, and the cotter pins are inserted into the bottom surface.
