Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a contact spring strip in which each contact spring is disposed in parallel chambers of an insulator, the insulator being one of the contact springs. The contact spring is composed of an upper part and a lower part which can be connected to each other when viewed in the extending direction, and the contact spring has a columnar connecting member projecting from the lower part.

In contact spring strips such as those described in "Prior Art", the column-shaped connecting elements are inserted into the .xi. turns of the conductor plate. This method uses soldering T to connect the connecting member and the conductor plate.
This is a connection technology to avoid the use of However, in this case, /? Pushing the connecting member into the turn hole
It is necessary to ensure that the contact spring leg of each contact spring located in each chamber of the contact spring strip does not undergo deformation due to the action of the intrusion pressure on the connecting member, which occurs at one time.

OBJECTS OF THE INVENTION It is therefore an object of the present invention to improve a contact spring strip of the type mentioned at the outset so that it can safely and reliably absorb the forces that occur during the pushing of the connecting element, and that in this case the function of the contact spring element is improved. It is to provide something that is not a hindrance.

According to the present invention, there is provided a first position and a second position perpendicular to the extension of each contact spring between the part and the lower part. An insulating material plate is disposed slidably supported between the insulating material plate and the insulating material plate is surrounded by each bar-shaped wall portion which overlaps the upper Ω chamber in a first position, and each of the insulating material plates has an aperture. one of the bar-shaped walls in the second position of the insulating plate is positioned over the contact spring side end of the connecting member, thereby Resolved.

Effect: In the first position of the insulation plate, each opening of the insulation plate is aligned with a respective chamber of the part, so that the insulation phase plate slides over the connecting member of the contact spring located in the upper part. It is thereby possible to move smoothly within the second part.

Embodiments According to one embodiment of the invention, the lower part has at least one projection at the edge of the plate that projects into the area of the plate and locks the plate in the second position. , the protrusion and the plate have inclined surfaces adjusted to each other.

Advantageously, the insulating phase plate automatically slides into the second position when the upper part and the lower part are connected by means of the screw and is secured in this second position.

According to another embodiment of the invention, the contact spring has a plurality of contact spring legs attached to a longitudinal strip extending in the direction of extension of the contact spring, which longitudinal strip is attached to the upper part and the plate. is disposed outside the projection range of each wall in the second plate position and is supported by the upper step with the end on the contact spring side, and further The ends of the longitudinal strips, which are bent towards the connecting element in the lower region, are welded to the connecting element with the section that rests against the connecting element.

In this construction of the contact spring, the longitudinal strips serve for the precise positioning of the contact spring in the upper part and prevent the welding process between the contact spring part and the connecting part of the contact spring. It is advantageous to shift the contact point within a range that does not adversely affect the spring action of the spring leg.
A vertical strip is also supported in the upper crotch area, forming a stop to ensure that each contact spring remains in the correct position when the insulation plate is moved from the first position to the second position. Sa1. ing.

According to a further embodiment of the invention, the end of the connection part supported on the wall is enlarged in the region of the lower part, at least in a direction parallel to the insulation plate, and Formed by expanding the connecting member within this lower area.
The step of the connecting member rests on a corresponding corresponding contour of the lower part.

This provides, on the one hand, a better supporting effect of the connecting part to the insulation plate and, on the other hand, that the contact spring is not locked in the strip body of the contact spring strip even in the direction opposite to the direction of installation of the contact spring. There is.

DESCRIPTION OF THE PREFERRED EMBODIMENTS As can be seen from the drawings, the contact spring strip has an insulator consisting of an upper part 1 and a lower part 2, which insulator has a plurality of chambers 3 for receiving the individual contact springs. There is. individual room 3
is arranged with a predetermined chisel turn and is formed through the contact spring strip between its front face 5 and its lower face 6. A column-shaped connecting element 7 projects from the lower side 6 of the contact spring strip and from the lower part 2, that is to say from the strip housing.

This connecting element 7 forms, together with the contact spring element δ, an individual contact spring.

The column-shaped connection member 7 of the contact spring is pushed into the ξ turn hole 9 of the conductor plate 10 and is formed so as to cover it (
Figure 2). In this case, the force necessary to force the connecting member 7 into the ξ-turn hole 9 can sometimes damage the contact spring member 8 of the contact spring, and the connecting member 7 It must be possible to communicate to others. For this purpose an insulating material 1-]-1 is arranged in the strip body between the part 1 and the lower part 2 which is engageable with the second part 1, and this insulating material Play 1-1. ]- are arranged within the strip body at right angles to the direction of extension of the contact spring. A plate 11 is slidably supported between the upper part 1 and the lower part 2.

An opening 12 surrounded by a bar-shaped wall 13 is formed in the insulating plate 11 . This opening 12
The insulating material plate 11 is connected to the contact spring of the connecting member 7
Place it over the top and fit it inside the upper part 1. In this case the insulation plate 11 is in the first position. In this position the opening 12 is aligned with the chamber 3 in the upper part 1.

The contact spring 4 has two contact spring legs 14 in the area of the contact spring element 8, which legs 14 are located opposite each other and extend in the direction of extension of the contact spring. A contact gap is formed at the free ends of both contact spring legs 14 adjacent to the upper surface 5, into which a contact knife or contact pin can be introduced. Contact spring leg 1
The other end of the contact spring 4 transitions into a U-shaped leg, each of which extends at right angles to the extension of the contact spring 4 and is joined within a longitudinal strip 15. The longitudinal strip 15 is of the chamber 3,
contacting the unjoined and opposite bright parts of both U-shaped legs, thereby positioning said contact gap in a precise position with respect to the opening in the upper part 1;
Through this opening a contact knife or contact pin is guided into the upper part 1 λ1. Get it. The free end of the longitudinal strip 15 on the side of the contact spring abuts against the step 16 of the upper part 1;
The depth of insertion of the contact spring Φ into the second part 1 is determined by .

Each longitudinal strip 15 passes through an opening 12 in plate 11 and
Bend portion 17 within the lower part 2 of the lower side of the sillage 1-11
The warp 5 forms a section 18 that is even transverse to the extension of the longitudinal strip 15, and this section 18 allows the longitudinal strip 15 to form a columnar connection section 7. He is proud of his connection.

When the insulating material plate 11 is slid in the longitudinal direction of the contact spring strip from the first position to the second position, the insulating material plate 11 is slid in the par-shaped wall 13 of the insulating material plate 11. t
The first piece is moved over the free end 19 of the connecting member 7. As a result, the force acting on the connecting element 7 in the axial direction and directed towards the upper part l is reduced by the insulating plate 1.
The plate 11 is transmitted to the wall 13 of the plate 11, and the plate 11 is
Since the air is supported by the plate 11, the air is further transmitted from the plate 11 to the upper part 1. On the contrary, the upper part 1 transmits the pressure acting on the upper part 1 with a line of action directed in the direction of extension of the contact spring to the insulating plate 11, from which the pressure is further transmitted. Via the free end 19, the contact spring is transmitted to the connecting member 7 of the connector.

When the lower part 2 engages the upper part 1 after the insulation plate 11 has been inserted into the receiving contour provided in the upper part 1, the narrow side of the plate 11 of the lower part 2 A wedge-shaped projection 2o provided along the plate 11 and projecting into the area of the plate 11 is compressed, during which the wedge-shaped portion is compressed between the plate 11 and the upper part 1. , co-operating with the corresponding chamfers of said plate 11, the plate 11 is moved from a predetermined first position to a second position by means of a stroke, during which the wall 1-3 automatically closes the free end 19. Second, let's slide.

An enlarged part 21 is arranged on the connecting part 7 in the area of the lower part 2, by means of which a free end 19 to the wall part 13 is connected on the one hand.
The support surface of the lower part 2 is enlarged, and on the other hand, steps 22 located within the region of the lower part 2 are formed at appropriate points along the entire length of the connecting member 7, with the corresponding steps of the lower part 2 facing each other. There is. By the engagement of the lower part 2 and the upper part 1 following the fitting of the lower part 2 to the connecting member 7 and the pulling, the lower part 20 is brought into contact with the stepped part 22 of the connecting member 7.
