Description

[Detailed Description of the Invention] The present invention relates to a coupling device between a relay and a socket in which each terminal of the relay is inserted into the terminal hole. Or, there is less risk of misdirection or mistake when attaching the socket to the printed circuit board, and it is easy to attach and detach the relay to the socket, as well as a relay and socket that allows the relay to be attached to the socket reliably. It is to provide a coupling device for.

The present invention will be described in detail below based on the illustrated embodiment. In the figure, reference numeral 1 denotes a relay, and a protrusion 2 is provided protruding from the lower part of one side in the longitudinal direction of the relay, from which a plurality of terminals 3 protrude from the lower surface. Reference numeral 4 in the figure is a socket having a plurality of terminal holes 5 on the upper surface and a blade receiving spring 8 protruding from the lower surface for attachment to a printed circuit board (not shown). Locking claws 6 and 7 are provided upright. The upper ends of each of the locking claws 6 and 7 are bent toward the opposite side, and one of the locking claws 6 is made considerably lower than the other of the locking claws 7. When installing the relay 1 into the socket 4 by inserting each terminal 3 of the relay 1 into the terminal hole 5 of the socket 4, first bend the tall locking claw 6, then bend the short locking claw 7. Since the height of both the locking claws 6 and 7 is the same, it is smoother than when both the locking claws 6 and 7 have to be bent at the same time. It can be worn easily.

As described above, in the present invention, since a pair of locking claws of different heights are provided upright from both ends of the upper surface of the socket, the socket has directionality, and therefore, it is possible to attach the socket to a printed board, etc. This reduces the risk of making mistakes when installing, and at the same time, when installing a relay in a socket, it will not be possible to install the relay unless the two sides are aligned, and the relay itself will also be difficult to install due to the protrusions on the side. Since it is directional, it is possible to install the relay into the socket without making a mistake.Furthermore, since both locking claws are locked, the relay can be installed securely. Since the heights of the two locking claws are different, when installing the relay into the socket, first bend the taller locking claw, then bend the shorter locking claw, and then insert the relay terminal into the socket. It is only necessary to insert the relay into the socket, and there is no need to bend both locking claws at the same time.Therefore, the relay can be smoothly attached to the socket.
