Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a printed circuit board connector to which a socket for connecting a flat cable is connected.

[Background technology]

This type of printed circuit board connector generally has a socket for connecting a flat cable.
A' are arranged in a line so as to be substantially parallel to the periphery of the printed circuit board 6, as shown in FIG. By the way, in the conventional connector A', the lever 7' for unlocking and detaching the socket 1 is rotatable in a plane parallel to the longitudinal direction of the connector A', and the lever 7' is rotatable in a plane parallel to the longitudinal direction of the connector A'. It was necessary to set the distance l to ensure rotation of the lever 7' in the direction indicated by the arrow. Therefore, there was a problem that the connectors A' could not be disposed closely together. Furthermore, if the lever 7' is made longer in order to increase the detachment force of the socket 1 by the lever 7', the distance l becomes larger.
There was a problem that it was difficult to increase the withdrawal force of socket 1.

[Purpose of invention]

The present invention was developed in view of the above points, and it is possible to reduce the distance between the printed circuit board connectors arranged in a row, thereby saving space and easily reducing the detachment force of the socket. The purpose of this invention is to provide a printed circuit board connector that can be made larger.

[Disclosure of invention]

(Embodiment 1) Fig. 2 shows an embodiment of the present invention, in which 1 is a socket for connecting the flat cable 5, and 2 is a socket for connecting the flat cable 5 to the socket 1.
This is a holder that connects the housing 10 of the socket 1 and holds the flat cable 5.
Holder 2 is attached to a convex portion 11 protruding from the longitudinal end surface of
The holder 2 is fitted onto the socket 1 by engaging the protrusion 21 of the arm 20. 3 is an elongated box-shaped header with an open top, 4 is a post protruding from the bottom of the header 3, and when the socket 1 is inserted into the header 3, the connecting fitting (not shown) of the socket 1 is connected to the post 4. Each wire of the flat cable 5 is electrically connected to the post 4. Reference numeral 7 denotes a lever that is removably pivoted to the longitudinal end of the header 3 and is rotatable in a plane perpendicular to the longitudinal direction.
The housing 10 of the socket 1 is provided with a cam portion 7a that engages with a protrusion 12 projecting from the longitudinal end of the housing 10. 31 is a shaft hole into which the shaft portion 7b of the lever 7 is inserted; 32 is a lock protrusion into which the hook 22 provided at the tip of the arm 20 of the holder 2 is engaged; when the socket 1 is inserted into the connector A; The hooking pawl 32 engages with the lock protrusion 32 and the socket 1 is closed.
It is now possible to prevent this from falling out. 33 in the figure is a notch groove into which the positioning protrusion 14 of the socket 1 is inserted, and the positioning protrusion 14 and the notch groove 33
Since the socket 1 cannot be inserted unless the two are engaged, reverse insertion of the socket 1 can be prevented.

(Operation of Embodiment 1) When inserting the socket 1 into the connector A, insert the socket 1 into the header 3 with the lever 7 removed, so that the connection fitting of the socket 1 is attached to the post 4. Each line of the flat cable 5 is connected to the post 4 by elastic contact. At this time, the hook 22 at the tip of the arm 20 of the holder 2 engages with the lock protrusion 32 of the header 3, and the socket 1
This will prevent it from coming off. Next, when detaching the socket 1 from the connector A, insert the shaft portion 7b of the lever 7 into the shaft hole 31 of the header 3 and remove the lever 7.
is attached to the header 3, and when the lever 7 is turned in the direction of the arrow Y in a plane perpendicular to the longitudinal direction of the header 3, the cam part 7a moves into the protrusion 12 protruding from the end surface of the socket 1.
is pushed up, and the socket 1 is driven in the detachment direction. In addition, when installing the lever 7, the arm 20
is pushed outward, and the hook 22 and lock protrusion 3
The lock caused by 2 is now released. In addition, since the lever 7 is made into a jig so that it can be attached to and detached from the header 3, if one set of levers 7 (one for the left end and one for the right end) is prepared, a large number of connectors A can be connected.
The socket 1 can be disconnected and the connector
Compared to the conventional example in which the lever 7 is incorporated in A', the structure is simpler, the size can be reduced, and the cost can be reduced.

(Embodiment 2) Fig. 3 shows another embodiment, in which the structure of the shaft attachment part of the lever 7 is changed, and an arcuate bearing recess 35 is provided at both ends of the header 3, and a protrusion is provided. A retaining wall 37 with a lever 7 protruding from the lever 7
A shaft portion 7c having a semicircular cross section is provided at the lower end of the holder, and a recess 7d into which the protrusion 36 is fitted is bored on the side surface.
When the lever 7 is press-fitted between the end surface of the header 3 and the retaining wall 37, the shaft portion 7c fits into the bearing recess 35, and the protrusion 36 of the retaining wall 37 engages the lever 7.
The lever 7 is engaged with the recess 7d of the header 3, and the lever 7 is rotatably attached in a plane orthogonal to the longitudinal direction of the header 3.
Here, the upper surface of the cam portion 7a that engages with the protrusion 12 of the socket 1 is an ellipsoidal surface, so that the socket 1 remains unchanged even when the lever 7 is rotated in any direction from the vertical position.
is driven in the detachment direction. Further, by simply press-fitting the lever 7 between the end face of the header 3 and the retaining wall 37, the protrusion 36 is engaged with the recess 7d, thereby preventing the lever 7 from falling off. Parts such as shaft pins can be omitted.

[Effect of idea]

As described above, the present invention has a plurality of posts that are in elastic contact with the connection fittings of the socket arranged in a row in an elongated box-shaped header with an upper opening into which a socket for connecting a flat cable is inserted, and the longitudinal direction of the header is In a printed circuit board connector that is arranged in a row on a printed circuit board so as to be substantially parallel to the periphery of the printed circuit board, a cam portion that engages with a protrusion protruding from the housing end of the socket is provided at the longitudinal end of the header. A lever equipped with a header is pivoted so as to be rotatable in a plane orthogonal to the longitudinal direction of the header, and the socket is driven in the detachment direction by rotating the lever in a plane orthogonal to the longitudinal direction of the header. This makes it possible to reduce the distance between the connectors arranged in a row along the periphery of the printed circuit board, saving space, and by increasing the length of the lever appropriately. This has the effect of easily increasing the detachment force.
