Abstract

PROBLEM TO BE SOLVED: To provide a high electric current transmitting contact which can bridge mutual contact pieces being connecting objects in a very large tolerance range in a limited installing width by a limited space requirement. SOLUTION: A contact 100 has parallel plural contact webs 105 arranged so as to cross at a right angle to the axis 110 while extending along the axis 110, and these contact webs 105 mutually connect its end part to a base surface 6, and raise up a central part by a height (j) from the base surface 6. Large tolerance bridging for a minimum installing space is attained by substantially bending the contact webs 105 in a V shape. The respective contact webs 105 are divided into two rectilinear leg parts 107 and 112 having the same length, and these two leg parts form a bending angle α smaller than 180 degrees, and an electric contact point to a contact surface 2 is formed in a curved area of the contact webs 105.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of electrical contact technology, and more specifically, a contact element for electrically connecting two contact pieces with their contact surfaces opposed to each other. Regarding This contact is
A plurality of mutually parallel contact webs extending perpendicularly to the axis and extending perpendicularly to the axis.
tact web), the contact web being configured to interconnect its ends in the base plane and to raise the central section from the base plane at a constant height.

[0002]

2. Description of the Related Art A contact of this type is disclosed in European Patent Publication
It is disclosed in EP-A2-202 564. However, the contacts disclosed therein are only suitable if, due to their geometry, the bridging tolerance between the contact pieces is in the range of a few tenths of a millimeter.

[0003]

In electrical engineering,
Whether the two contact surfaces are flat or curved, and also
Even if they are surfaces separated from each other, it is often used to bring them into contact with each other by using a contact having an elastic structure. High currents often have to be transmitted through such contacts.

In particular, the contact surface spacing of the two contact strips in high current transmission systems, relay systems and other electrical installations can be significant as a result of deviations in manufacturing tolerances and / or deviations in existing shapes and positions. fluctuate. Therefore, the ideal electrical contact is the conductive cross section of the contact piece.
ive cross-section There is a minimum space requirement of minimizing loss and contact mounting width.
The maximum tolerance range of e) must be filled.

At the same time, while considering the above-mentioned maximum tolerance and change in position, it is necessary to ensure current transmission that actually occurs not only during normal operation but also during failure (short circuit). The manufacturing costs of the contacts are low, their installation is simple and the limited processing of the contact pieces must also be clearly guaranteed.

Although the weights of their roles are different, various contactors satisfying at least some of the above requirements are known. In many cases, known contacts are based on spring elements made by stamping. For example, German Published Patent Specification DE-OS 1 665 132 discloses a contact having two parallel, straight side edge strips between which a contact web separated from each other by a slit is arranged. ing. The two ends of the contact are formed in an arc shape so as to be mirror-symmetrical near the center part, and when the contact web is folded back with respect to the axis of the contact surface, the arc-shaped end of the contact piece is formed. It is configured to contact the adjacent contact surface. The maximum bridgeable spacing between the contact surfaces (tolerance briding) depends decisively on the contact web width. The width of the contact web is limited in order to store a sufficient number of contact webs in a given width of the contact current for the target transmission current per unit length of contact, and as a result the tolerance bridges have corresponding limits. Is done.

By increasing the spacing of the grids, ie by increasing the center spacing of the contact webs, it is possible to increase the width of the contact webs and thus the tolerance bridge.
However, this leads to a reduction in the number of contact webs per contact length unit and presupposes a wider contact width. However, German published patent specification DE-OS 2243
As disclosed in 034, contact webs per unit length of contact can be obtained even with a certain tolerance bridge as long as the contact webs partially overlap and the side edge strips are undulated. It is possible to increase the number of. But,
Such contacts add manufacturing complexity and cost. Furthermore, the overlapped side edge strips also constitute a mechanical weakness.

Another structural solution is described in European Patent Publication EP-A1-520 950. When the grid spacing is narrow and the contact width is moderate, the upper and lower boundaries of the contact webs are brought into mutual engagement near the center, resulting in a larger effective contact web width and a larger tolerance bridge. It becomes possible to obtain a connection.

However, considering the two main requirements of minimum mounting space and sufficient current transmission, the proposed solution does not guarantee a high tolerance bridge in the desired millimeter range. Therefore, precise preparation for attaching the contact piece to the contact piece, i.e. refinishing of the contact piece, is required. Furthermore, all the contacts produced by the stamping process described above are complicated in their installation (see, for example, FIGS. 1 and 2 of German Patent Publication DE-OS 1 665 132 and European Patent Publication EP- Figure 1 of A1-520 290
And the holes formed in Fig. 2) must be provided,
If the shape is large, another fixing element must be prepared to fix the contactor in the hole.

Another technical solution uses electrical contacts which are formed in the form of coil springs using wires. British Patent 1 542 102 describes a contact of this kind for round or flat contact strips. German patent specification DD-A1-244 438 proposes an additional position-stabilizing element for this type of contact. A spiral contact element using a wire is described in EP-A1-314 229 and EP-A1-573 690 for a cylindrical contact piece. The advantage of the contacts belonging to this group is that a considerable tolerance bridge is obtained if the number of contact webs per length unit is sufficiently large.

It is certainly possible for the contact according to the coil spring principle to meet the main requirement, namely the requirement of a large tolerance bridge with sufficient current transmission. However, the considerable loss of the conductive cross section of the contact piece associated with the proposal of such a solution must also be taken into account. Therefore, an unavoidable prerequisite for the use of these contacts is that there is a large enough mounting space to compensate for the problem of conductive cross section reduction such as narrow passages. This requires a significant increase in contact size compared to the required conductive cross section for current transmission, which is a requirement in the case of relay systems, which is also one of the fields of use of contacts.
Due to its limited installation conditions, it is not easily accepted.

Finally, European patent publication EP-A2-202 56
No. 4 discloses a contact in which a parallel contact web is not folded back about its axis, but instead is arched from the substrate surface (see in particular FIGS. 1 and 6 thereof).
One of the contact surfaces is in contact with the curved central region of the contact web and the other contact surface is in contact with a web bridge interconnecting the ends of the contacts. But,
As a result of the uniform curvature, when pressure is applied, a deformation of the contact element with respect to the contact web occurs, which on the one hand does not provide sufficient spring deflection and, on the other hand, a distinction in the central region of the web. The number of contacts will not be limited.

Therefore, an object of the present invention is to transmit high-current transmission capable of bridging within a very large tolerance range between contact pieces to be connected in a limited mounting width with a limited space requirement. Is to provide a contactor.

[0014]

This contactor solves the above-mentioned problems as follows. That is, the contact webs are bent into a substantially V-shape to divide each contact web into two substantially linear legs of equal length, the legs forming a bend angle of less than 180 degrees with each other. Thus, electrical contact to one contact surface is made in the curved region of the contact web. Clearly defined contact is V
Obtained through the bent part in the mold. The straight legs form a spring element which is clearly optimized with regard to the spring properties, in particular the flexibility of the spring, as well as the transmission of current.

The first preferred embodiment of the contact according to the invention is characterized by the following points. That is, the contact web is constituted by a metal strip, the contact web having its maximum width in the curved region, each leg having a taper increasing towards its center, the minimum width of that part being the web. Is narrower than the maximum width. By appropriately selecting the ratio of the leg length to the minimum web width and the thickness of the metal strip material, it is possible to change the spring area and the current transmission property in a wide range and adapt it to specific use requirements. can do.

A second preferred embodiment of the contact according to the invention is characterized by the following points. An arch is formed in the curved region of the contact web in a direction opposite to the bending direction of the contact web and the contact web further comprises a taper near the arch. As a result, it is possible to increase the number of contacts in a clearly defined form without giving any great change to the spring characteristics of the contact.

In another preferred embodiment, a plurality of side edge beads (b) are provided parallel to the axis in the contact area of the contact web.
Preferably, eads) are formed and the side edge beads face away from each other with respect to the V-curve of the contact web. When attaching a contact of limited length that does not connect the ends by this side edge bead to the straight hole,
This is possible without the use of additional fixing elements.
Furthermore, a single line contact is formed which is located at least in strips along the axis of the contact.

Yet another preferred embodiment of the contact according to the invention is characterized by the following points. The contact web is
A pair of web bridges parallel to the axis are alternately connected to each other on the left and right sides. As a result of this alternating connection or alternating free cut provided between the contact webs, the contactor becomes spring-like in its axial direction. The nature of this spring is utilized to form a locking element for sockets or plugs of any shape by connecting the end webs (connecting webs) of finite length contacts.

Yet another preferred embodiment of the contact according to the present invention is characterized by the following points. The bent contact is inclined at an average inclination angle of 90 degrees or less with respect to the base surface,
Alternately connected on the left and right sides by respective web joints, the contact webs and web joints are made of wire and the contacts are made of hammer bent wire, or they are made of metal strip material And the contacts are formed by punching and bending the strip material.

[0020]

As described above, the above contactor has a simple structure, is easy to process, and can be flexibly applied to various uses in a connected state. Further embodiments will be apparent from the claims which follow.

[0021]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail with reference to the embodiments of the present invention and the accompanying drawings.

The embodiments of the contact according to the invention described below can be divided into three basic forms. The contacts of the first basic type (FIGS. 1 to 3) and the second basic type (FIGS. 4 to 6) are
It can be manufactured by subjecting a metal strip to a simple punching and bending process, and the contactor of the third basic form (FIGS. 7 to 9) can be formed by bending a wire with an inexpensive hammer. It is possible. The fact that the first basic type and the second basic type contacts have a large spring area with a minimum mounting space is derived from the optimum geometrical dimensions of the contact web,
Also, the fact that the third basic form has a large spring area in the smallest mounting space results from the optimum torsion-bending connection due to the simultaneous tilting of the contact web with respect to the base surface.

Providing an optimal grid spacing with respect to the width of the contacts makes the first to third basic type contacts particularly suitable for use as high current contacts. The first basic type contactor has an open end. The contacts are pressed into webs on both sides of the edge (web bridges) and through the side edges of the beads that form the leg contacts, the straight holes of the large diameter sockets and plugs (ie, without dovetail guides: without a dovetailguide) without additional holding elements.

In the case of a contact having a loop or chain shape, that is, a contact having both ends connected and closed in an annular shape, the second basic type and the third basic type contacts can fold back themselves and take time-consuming pre-rolling. It can be applied to sockets and plugs without prerolling or refinishing. Further, since the second basic type and the third basic type contacts are in a chain state, the contact piece can be provided with a straight hole that does not require manufacturing time and cost. Moreover, chained contacts do not require the additional retainer elements for contact locking normally used with larger diameter plugs and sockets, due to the nature of their axial springs. This axial elasticity allows the use of contacts for plugs and sockets of various diameters.

[0025]

FIG. 1 shows a contactor 100 made into a sawtooth shape (jig saw) by punching and bending from a strip material. A contact 100 extending along the axis 110 comprises a contact web 105 having a plurality of thicknesses c arranged at right angles to the axis 110 with a grid spacing f.
The contact webs are connected at their opposite edges to each other by a continuous web bridge 104 or 106 of width k (FIG. 1b). The contact web 105 is bent into a front V shape so as to have a top with a radius R3 (FIG. 1).
a). Thus, each contact web 105 is divided into two equal length legs 107 or 112 between the curved region and the web bridge 106 or 104. As a result of this bending process, the two legs 107, 112 form a bending angle α of less than 180 degrees. The curved region is the base surface 6

It is derived from the planned tapered portions 109 and 111. 3. By appropriately selecting the ratio b / a of the leg length to the minimum web width and the web thickness c, it is possible to change the spring area and the current transmission in a significant range. 4. Each contact web 105 has two leg contacts 102, 1
03 and one top contact 101. 5. The radius R2 (FIG. 1a) of the leg contacts 102, 103 curved in a bead shape so that the leg height is about h ensures a line contact area along all the contacts, and the side edge beads. By varying the depth and width of 115, 116, different usability possibilities can be determined. 6. Also, radius R3, maximum web thickness e, and α <18

The maximum web width e, the cut width g between the contact webs 105 (FIG. 1b), the web thickness c, etc. are taken into consideration and selected as small as possible. 8. The width i and the height j of the contact can be variously set by selecting the leg length and the bending angle α. 9. The radius R4 (FIG. 2) for laterally rounding the contact web 105 allows the contactor 100 to be used at any angle relative to the axis 110 and occurs when used perpendicular to the axis. Reduce scratches. 10. The width k of the web bridge has various radii of curvature R5,

Each of these contact webs 105 is V-bent and divided into linearly extending legs 407, 412 of equal length with corresponding tapered portions 409, 411.

Contact web 405 has the same geometry, contact angle, stamping 408 as contact webs 105 and 305 shown in FIGS.

However, because the web bridges 404, 406 are short, the line contact areas 414 are not formed through the web bridges, but at regular zones (FIG. 5).

The characteristics of the contact 400 can be summarized as follows. 1. The contact web 405 of the contact 400 is based on the principle of a leaf spring and therefore acts like an ideal spiral spring. 2. A spring having a large deflection width of the contact web 405 has a minimum web width a, a leg length b, and a taper portion 409.

The lattice spacing f is selected to be as small as possible corresponding to the maximum web width e, the cut width g between the contact webs 405, and the web thickness c. 8. The width i and the height j of the contact can be variously set by selecting the leg length and the bending angle α. 9. Radius of curvature R4 on both sides of contact web 405 (FIG. 5)

b) gives the contactor 400 a spring characteristic in the direction of the axis 410. 12. The geometric shapes of the free cuts 419 and 420 are determined by various amounts such as the double web width d, the lattice spacing f, and the radius of curvature R5. 13. With the shape described above, the contact 400 can be made in a limited length. 14.

In this case, the dimensioning is performed by replacing the wire diameter a with the web width a. The stamped contact web is provided with a radius of curvature R4 according to FIG. 9 so that the contact can be used at any angle with respect to its axis and to reduce scratches when used at right angles.
