Description

Connector for board connection

technical field

The present invention relates to a connector electrically connected to a plurality of connected terminals fixed on one side of a substrate.

Background technique

Module substrates such as LEDs are mounted on one side of the substrate, and a plurality of module substrates of a predetermined length are electrically connected in the horizontal direction to be used as long-sized LED lamps and the like.

As shown in FIG. 7 , sockets 140 , 140 are fixed to one surface near the ends of the substrates 40 , 40 , and the sockets 140 , 140 are connected by a connector 110 having plate-shaped connection terminals.

However, in recent years, the demand for high-density LED lamps with a small distance between LEDs has increased. The connection method shown in FIG. 8, the sockets 140A and 140A are respectively fixed on both sides of the substrate 40 by sandwiching the LED2 between them as shown in FIG.

However, if the plug connectors are provided for each corresponding socket in this way, the plug connectors must be operated twice in the assembly operation, and in the case of 3-pole connection, the operations must be performed three times, which increases the assembly man-hours.

In addition, since the size of the plug connector is reduced, it is easy to make it difficult to confirm the connection direction.

In addition, there is a problem that the allowable range capable of absorbing the center shift and inclination of the substrates becomes smaller.

For example, Patent Document 1 discloses a connector for connecting substrates in the horizontal direction, but this connector also corresponds to the structure shown in FIG. 7 .

The connected terminals fixed on the above-mentioned substrate are elastically connected.

The present invention has the following beneficial effects.

When the present invention connects a plurality of substrates to each other in the horizontal direction, or when a plurality of cables are drawn out from one side of the substrate, a plug portion that is electrically connected to each of a plurality of connected terminals fixed on the substrate is formed, and the elastic deformation is allowed. The coupling portion connects the plurality of plug portions, thereby absorbing mounting misalignment of the connected terminals mounted on one surface of the substrate and mounting misalignment of the substrate.

A configuration example of the connector of the present invention will be described using FIGS. 1 to 3 .

This embodiment is an example in which the socket is fixed on the board side and the connector part is a plug connector, but the connection structure of the plug and the socket may be reversed.

On the substrate 40, a plurality of LEDs 2 are mounted at equal intervals in the longitudinal direction, and two socket terminals as the first connected terminal 41 and the second connected terminal 42 are fixed (mounted) near the end of one side of the substrate with solder or the like. .

The receptacle terminals (41, 42) fixed on the same surface of the two substrates are arranged in a horizontal direction so as to face each other, and are fitted into the connector 1 from above to be electrically connected.

As shown in FIG. 2 , the connector 1 connects the first connector part 10 and the second connector part 20 in a direction perpendicular to the connection terminals by using the joint part 30, and the first connector part 10 is fixed in the horizontal direction as The first connection terminal 12 of the shaft of the thin round rod is constituted by the first case 11, and the second connector part 20 is constituted by the second case 22 for fixing the second connection terminal which is also in the shape of a shaft in the horizontal direction.

In this embodiment, the first connector part 10 and the second connector part 20 have the same structure, and are fixed shafts in the plug receiving parts 11b, 21b provided on the first and second housings in the horizontal direction. Examples of (12, 22).

The coupling part 30 connects the first connection part 31 and the second connection part 32 with an elastic part 33 which deforms elastically.

The shape of the elastic portion 33 is not particularly limited as long as it can be elastically deformed left, right, and up and down. The present embodiment is an example formed by arranging arcuate coupling pieces 33 a and 33 b facing each other.

In this embodiment, the coupling part 30 is formed separately from the first and second connector parts 10 and 20, and the second housing 21 is used as a representative for illustration. The locking part 21c on the housing side and the connecting part The inner locked portion 32a is locked and combined.

Furthermore, the joint 30 can be made as a joint 30a integrally formed on the housing as shown in Figure 5(a), and the joint part can also be integrally formed, and now as shown in Figure 5(b) By serializing the length of the joint portion 30b, it is possible to use a common connector portion for substrates with different intervals between the socket terminals.

In addition, as long as the shape of the joint portion 30c is a shape that allows elastic deformation, as in the shape of the joint portion that is alternately folded left and right as shown in FIG. 5( c ), the shape is not limited.

The first and second socket terminals (41, 42) have the same shape. If the socket terminals on the substrate side as shown in FIG. Two pairs of contact terminals 41a, 41a and contact terminals 41b, 41b facing each other) and a pair of locking pieces 41c, 41c locked to locking claws 21a provided inside the case.
