[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board-mounted connector mounted on a board for connecting a board to a cable.

[0002]

2. Description of the Related Art With the miniaturization or high density of electric products, there is an increasing demand for high density of connectors used in the housing of the product. In accordance with the demand, a board horizontal mounting type two-stage connector is supplied to the market as one of the connectors corresponding to the high density. This two-stage connector was one in which two single connectors were molded or one in which the two connectors were split vertically. In this vertical split type, the upper and lower connectors are simply fixed with screws or split pins. (See FIG. 3).

[0003]

However, in the above-described two-stage connector for horizontal mounting on a board, the individual connectors are integrally formed or, as shown in FIG. 3, the individual connectors 1 ', 2' are formed. It was not possible to adjust the spacing between the single connectors in order to fix them together with screws, split pins and the like. A single integrated or co-molded connector does not work, as it is often necessary to adjust the space to accept a secure connection.

The present invention has been made in view of the above-mentioned conventional problems, and provides a board-mounted connector which can easily change the interval between a plurality of juxtaposed single connectors. The purpose is to do so.

[0005]

In order to achieve the above object, a board mounted connector of the present invention is mounted on a board.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments will be described below with reference to the drawings. 1 and 2 show a board-mounted connector according to an embodiment of the present invention. As shown in FIG. 2, reference numerals 1 and 2 denote a single connector for connecting a commonly used board and a cable, 3 denotes a spacer located between the single connectors 1 and 2, and 4 denotes a single connector of these single connectors. It is a joint block for engaging with the spacer 2 and the spacer 3, respectively, to integrate them. The unitary connectors 1 and 2 have the same shape and dimensions, respectively. At least one end thereof has engaging holes 12 and 22 for positioning, and a connector formed of a two-step groove located at the end face of the end. Mating grooves 14 and 24 are provided. In addition, a spacer 3 sandwiched between these single connectors 1 and 2
Are formed at opposing positions on the upper and lower surfaces thereof and are engaged with the engaging holes 12 and 22 of the unitary connectors 1 and 2 in a state of being sandwiched therebetween (only the upper surface in FIG. 3 is shown); Locking portion 34 having a claw, and a single connector 1,
A pinched portion 36 that determines the interval between the two is provided by molding. And the joint block 4 is attached to these unitary connectors 1 and 2 and the spacer 3,
At a distance corresponding to the distance between the individual connectors 1 and 2 with the spacer 3 interposed therebetween, the individual connectors 1 and 2
At a distance corresponding to the engaging grooves 14 and 24 of the single connector 1 and the fitting protrusions 42 and 44 formed in two steps of large and small steps corresponding to the engaging grooves 14 and 24 of the unitary connectors 1 and 2, respectively. A locking member 46 having a claw or the like for locking to the claw of the locking portion 34 of the spacer 3 is formed by integral molding. By these fitting projections 42 and 44 and the locking member 46,
The joint block 4 is a detachable single connector
-1, 2 and the spacer 3 are separated in the opposite direction of the upper and lower surfaces.
Can be fixed integrally so as to prevent

With the above-described configuration, positioning of the single connectors 1 and 2 and the spacer 3 is performed by press-fitting the projection 32 of the spacer 3 into the engaging holes 12 and 22 of the single connectors 1 and 2. . For this reason, assembly can be performed accurately and easily. The upper and lower portions of the single connectors 1 and 2 are fixed by fitting the fitting projections 42 and 44 of the joint block 4 with the engagement grooves 1 of the single connectors 1 and 2.
It is performed by being inserted and fitted into the 4, 24. At the same time, the joint block 4
2 and the spacer 3, the locking member 46 is locked to the locking portion 34 of the spacer 3 by a claw or the like, and the joint block 4 is connected to the unitary connector 1, 2.
Further, it is prevented from coming out of the assembly of the spacer 3 in the vertical direction, that is, in the facing direction. In this way, the board-mounted connector as shown in FIG. 1 is assembled integrally, and is mounted perpendicularly to the board by the mounting pins (not shown) formed on the connector. If the height of the spacer 3 and the dimensions of the joint block 4 are changed, the joint block 4

Because it is flexible, the spacing between the single connectors 1 and 2 can be changed as necessary, and the spacing between the single connectors 1 and 2 can be easily changed without considering the design change of the connector itself. Can be.

In the above-mentioned board-mounted connector, the connector mounted on the board such that the connection direction axis of the single connector is perpendicular to the board surface is also 2 times.
Although the case where the layers are stacked has been described, it goes without saying that the present invention can also be applied to a connector arranged to be mounted in a direction other than the direction perpendicular to the substrate surface. In addition, even in a substrate in which single connectors are stacked in two or more stages, a corresponding number of spacers are used, and a corresponding number of fitting projections and locking members corresponding to the single connector intervals are integrally formed in the joint block. It is possible by forming or using multiple joint blocks.

In the above-mentioned board-mounted connector, in order to simplify the assembly process and reduce the number of parts, the positioning of the single connectors 1 and 2 and the spacer 3 and the fixing between the upper and lower portions are performed by the engagement holes and the engagement holes. The fitting projection, the engaging part, the locking part, and the fitting projection of the joint block 3 that engages with and locks them are fixed by the locking member. However, screwing, split pinning, press-fitting of the boss, ribs May be performed by fitting the groove and the like.
