DE2358561A1 - Female connector for cct. boards has spring-contact switch - is opened by slider driven axially by insertion of male connectors - Google Patents

Abstract

The female connector, for p.c. boards, has contact legs extending down through the p.c. board and formed into a leaf-spring switch at their inner ends. The springs are angled in towards one another so that they touch. An insulating slider runs along a keyway in the connector housing and has a wedge-shaped end that prises the two contacts apart. The contacts are opened out slightly to form a guide funnel for the wedge-shaped nose of the slider. Inserting the male connector drives the slider along to separate the leaf spring contacts whilst at the same time the male connector connects with the separated contacts.

Socket, in particular for printed circuit boards

The invention relates to a socket, in particular for printed circuit boards with an in or on Socket body arranged switch on one side clamped contact springs by means of - a plug over an actuating slide mounted in or on the socket body can be pivoted against a restoring force.

In the case of sockets equipped with switches, it is known to accommodate a slider in the area of an annular space receiving the connector sleeve, which can be moved longitudinally through the connector sleeve to pivot the contact springs of the switch _o In the case of sockets with an attached switch frame, the slide acts by means of attachments or the like. on the contact springs housed in the switch frame. With the well-known connector

The slide becomes bushing by exchanging or inserting it of sections adapted to the respective working lengths. All these sockets have one thing in common, that the connector sleeve makes movements of the slide in one direction, but not return movements makes possible. To apply restoring forces, springs are therefore used, which, as a disadvantage, increase the manufacturing costs and require a considerable amount of space. In addition, the spring force must be overcome with each plugging process.

It is the object of the invention to reduce the structural effort in sockets of this type. Furthermore is the aim of the invention is to reduce the insertion force to be applied to keep it low.

According to the invention, this is achieved in that the contact springs in the area of the actuating slide on the slide side About a part of the width are exhibited at an angle and protrude with the inclined surfaces in the path of movement of the actuating slide. The arrangement from both sides is expedient Symmetrical to the slide longitudinal axis on the socket body formed contact springs provided with their contact surfaces are permanently adjacent to each other due to pretensioning

and can be swiveled away by the actuating slide against the bias voltage. In a preferred embodiment, the actuating slide can bring to the bears with the Kontäktfedern to effect section, in particular at its free end with wedge surfaces _or the like od ₀ be provided which has a triangular shaped the slider in this area or enter trapezoidal cross-section "

In the case of the socket, this is the same as that of the contact springs applied spring force to generate the contact pressure and used to form the restoring force for the operating slide, which is under the influence of a transverse to Swivel plane of the contact springs on the inclined surfaces effective component of the spring force, e.g. the preload, is formed and the slide is removed when it is removed of the plug is automatically moved back from the socket into the starting position. It goes without saying that by more or less large exposure of the inclined surfaces and adaptation of the contact spring forces, especially the Preload, different sized contact and restoring forces are achievable.

It also corresponds to the invention that the contact springs attached directly to the socket body or in the switch frame.

are arranged, which firmly or detachably grip the socket body firmly and have access openings for the implementation of the actuating slide. In the application of switch frames, actuating slides of different lengths are to be provided, which is expedient by an exchangeable design and mounting of the actuating slide or by means of an operating slide can be achieved is made by inserting sections in length are changeable. When attaching several switch frames, the operating slide can also with approaches or the like. or be equipped at a distance formed wedge surfaces, which in turn with the contact springs Circuits come into effect.

How the invention can be carried out, shows with the essential features for these features das.in the drawing Embodiment, namely:

The socket body 1 takes in a known manner

Contact sleeves ", fork springs 2 .Od ₀ -dgl", which can be brought into effect with plug pins 4 of a plug 3. By soldering the angled lugs 2. · of the fork springs 2, the socket body 1 can be fixed to a circuit board 5 diant of the receptacle of a plug sleeve 3 'encompassing the plug pins 4. A switch frame 7 is attached to the socket body 1 (FIG have at the free ends contact surfaces 9. The deflection of the contact springs 8 takes place by means of an actuating slide 1.0, which is guided in a recess of the socket body 1 and protrudes with one end into the annular space 6 in such a way that when the plug sleeve 3 ^{1 is} pushed in the annular space 6 of the actuating slide 10 is pushed between the contact springs 8 (FIG. 3) and separates them from one another Contact springs 8 in the area of the side facing the actuating slide are bent over an angle of inclined surfaces 8 ′ to which, in the exemplary embodiment, basin surfaces 10 ′ on the actuating slide 10 are assigned. (Figure 4) The wedge surfaces 10 'extend essentially at the same angles as the inclined surfaces 8' to the slide ..

longitudinal axis. The Sohrägflachen 8 'have the task of exerting a restoring force on the actuating slide 10 pushed between the contact springs 8, under the influence of which the actuating slide 10 automatically returns to the front starting position when the connector sleeve 3' is removed from the annular space 6. The return movement of the actuating slide 10 continues until the contact spring 8 contacts the contact surfaces 9 again. It goes without saying that in the socket of Figure 1, several switch frames 7 one behind the other can attack the socket body 1 _o An actuating slide 10 of appropriate length, which is used by exchanging or by inserting sections, allows the simultaneous interaction with the contact springs.

In contrast, in the exemplary embodiment in FIG. 1, the contact springs 8 are firmly clamped in the socket body 1 held.

Finally, a ^{restoring force that can be applied by inclined surfaces 8 1 of} the contact spring 8 can also be achieved in the case of plug sockets with a single contact spring cooperating with a fixed contact.
