Description

Technical Field

[0001] The utility model relates to a relay and a new energy charging device. Background Art

[0002] A relay is an electronic control device that is usually used in automatic control circuits. It is actually an "automatic switch" that uses a smaller current to control a larger current. Therefore, it plays the role of automatic adjustment, safety protection, and circuit conversion in the circuit.

[0003] A conventional relay has multiple lead terminals extending from at least one side of its housing. Each lead terminal is used to connect to a wiring terminal. The mating surface of the lead terminal is a connecting piece, and the mating surface of each connecting piece is perpendicular to the arrangement of the multiple lead terminals. The connecting piece is typically connected to the wiring terminal using screws. When the screws are turned or the product is impacted or dropped, the wiring terminal is prone to deflection, making it difficult to maintain electrical clearance between adjacent wiring terminals.

[0006] Furthermore, the limiting portion includes a first limiting portion, and the first limiting portion is located at one end of the connecting piece in the arrangement direction of the plurality of lead terminals.

[0007] Furthermore, the first limiting portion is provided on the lead-out piece.

[0009] Furthermore, the limiting portion also includes a second limiting portion, which is located at the other end of the connecting piece in the arrangement direction of the multiple lead terminals; the connecting terminal connected to the connecting piece is limited between the first limiting portion and the second limiting portion.

[0010] Furthermore, the second limiting portion is provided on the connecting piece, and the second limiting portion is formed by folding the other end of the connecting piece in the arrangement direction of the plurality of lead terminals toward one side of the mating surface along the thickness direction thereof.

[0011] Furthermore, a connecting portion is integrally formed on a side of the connecting piece facing away from the mating surface, and the connecting portion is provided with a threaded hole passing through the connecting piece, and the threaded hole is used for threaded connection with a screw to lock the terminal block on the connecting piece.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Since the lead terminal is provided with a limiting portion, the limiting portion limits the connection terminal connected to the lead terminal to limit the connection terminal from deflecting toward the adjacent lead terminal.

[0017] 2. The limiting portion includes a first limiting portion and a second limiting portion.

DETAILED DESCRIPTION

[0030] In the present invention, the terms "first", "second", etc. are only used to distinguish similar objects, rather than to describe a specific order or sequence, and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, "plurality" means two or more. In the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "setting", "connection", etc. should be understood in a broad sense. For example, "connection" 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 a connection between the two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0031] See Figures 1-9 As shown, a relay of the present invention includes a housing 1, from at least one side of which extend a plurality of lead terminals 2 arranged in parallel and spaced apart. The lead terminals 2 include lead tabs 22 and connecting tabs 21 provided on the lead tabs 22 and used to connect to the wiring terminals 3. The thickness direction of the lead tabs 22 is consistent with the arrangement direction of the plurality of lead terminals 2. The surface where the connecting tabs 21 contact the wiring terminals 3 is a mating surface 212. The mating surface 212 of each connecting tab 21 is oriented perpendicular to the arrangement direction of the plurality of lead terminals 2. The lead terminals 2 are provided with a limiting portion that protrudes from the mating surface 212 and limits the wiring terminals 3 connected to the lead terminals 2 to prevent the wiring terminals 3 from deflecting toward adjacent lead terminals 2, thereby preventing the electrical gap between adjacent wiring terminals 3 from being reduced.

[0032] In this embodiment, multiple lead terminals 2 extend from opposite sides of the housing 1. Specifically, multiple lead terminals 2 extend from both sides of the housing 1 along its width. Two lead tabs 22 are located on the same side of the housing 1. The connecting tabs 221 on the two lead tabs 22 extend toward opposite sides of the two lead tabs 22. The mating surfaces of the connecting tabs 21 face the same direction. Therefore, the relay of the present invention has a total of four lead terminals 2 located on the outside of the housing 1, but this is not limited to this embodiment.

[0033] In this embodiment, the limiting portion includes a first limiting portion 221, which is located at one end of the connecting piece 21 in the arrangement direction of the plurality of lead terminals 2, and the first limiting portion 221 is provided on the lead piece 22. Specifically, the first limiting portion 221 is formed by a portion of the lead piece 22 extending in a direction perpendicular to the mating surface 212, and there are two first limiting portions 221, which are located at both ends of the connecting piece 21 in the length direction of the lead piece 22, and the length direction of the lead piece 22 is perpendicular to the outer side surface of the housing 1 where the lead piece 22 is located.

[0034] In this embodiment, the limiting portion further includes a second limiting portion 211, which is located at the other end of the connecting piece 21 in the arrangement direction of the multiple lead terminals 2. The terminal 3 connected to the connecting piece 21 is limited between the first limiting portion 221 and the second limiting portion 211. Specifically, the second limiting portion 211 is provided on the connecting piece 21 and is formed by folding the other end of the connecting piece 21 in the arrangement direction of the multiple lead terminals 2 toward one side of the mating surface 212 along its thickness direction. In this embodiment, a connecting portion 213 is integrally formed or fixedly connected to the side of the connecting piece 21 facing away from the mating surface 212. The connecting portion is provided with a threaded hole 214 that passes through the connecting piece 21. The threaded hole 214 is used to threadably connect with a screw to lock the terminal 3 to the connecting piece 21. Therefore, when the connecting piece 21 is connected to the terminal 3, no additional nut is required, which helps reduce costs, improves the assembly efficiency of the terminal 3, and reduces the loss of parts.

[0035] In this embodiment, some lead-out pieces 22 are integrally formed with the connecting piece 21, and some lead-out pieces 22 include a main lead-out piece 222 and an auxiliary lead-out piece 223. The main lead-out piece 222 is led out from the outside of the shell 1, and the auxiliary lead-out piece 223 is integrally formed with the connecting piece 21, and the auxiliary lead-out piece 223 is superimposed and connected with the main lead-out piece 222, and the first limiting portion 221 is provided on the auxiliary lead-out piece 223.

[0036] When connecting each lead terminal 2 to a terminal 3 of the relay of the present invention, the terminal 3 is first placed on the mating surface 212 of the connecting piece 21, between the first stopper 221 and the second stopper 211, and then tightened with a screw. The first stopper 221 and the second stopper 211 prevent the terminal 3 from deflecting left or right, thereby preventing the electrical gap between adjacent terminals 3 from being reduced.

The wiring terminals correspond to the lead-out terminals one by one, and each wiring terminal is respectively connected to the connecting piece of the corresponding lead-out terminal.

[0038] The utility model provides a relay and a new energy charging device, and the unrelated parts are the same as those in the prior art or can be implemented by using the prior art.
