Definitions

  • the invention relates to a one piece Sheet metal shaped base clamp with one each on one geometric thru axle arranged and in opposite Directional female and male contact part, the female contact part by two clamping tabs is formed, which in a central area of one laterally arranged connector are bent, so that in a section through the Central area the connector the base and the Clamping tabs form the two legs of a U, and which Clamping tabs in the direction of the thru-axle against their free ends towards each other as elastic contact flags.
  • the invention also relates to a base with a Base body made of insulating plastic, with in the base body trained terminal chambers and one base clamp each called genus.
  • the invention also relates to a method for Manufacture of base clamps of this type, in which Move the two sides of the connector Pre-bent clamping tabs and parallel to the direction of the thru axles and bent at right angles to the connector, and at most the male contact part twice across Thru-axis direction is bent approximately at right angles.
  • a socket clamp for one is now on the market Relay base known, which consists of a bent piece of sheet metal is made and a female and a male side having.
  • the female side is through two jaws formed which is U-shaped with a connector are connected.
  • the jaws point in the area of Connector a distance.
  • To the female The jaws run with a plug-in end Bias towards each other, touch on a line perpendicular to the direction of insertion and run again by one Distance apart.
  • a pin can be between the jaws be performed.
  • the maximum leg thickness is through that Insert opening in the relay base.
  • the male end is formed by a pin, which formed in the extension of a jaw and is bent twice at a right angle.
  • the pin is in a middle plane between the two jaws of the Jaws away, in the same direction and same level, in which a pin between the jaws should be performed.
  • the base body has a pit or chamber for each terminal.
  • the dimensions of the clamp and pit are matched so that the clamp is light can be introduced.
  • the open side of the pit is towards the relay pin directed and the clamp must be in the
  • the base body is inserted into the pit with the terminal pin first become.
  • An opening is provided in the pit floor through which of the terminal pins when inserting the terminal must be put through. So that the clamps in the base are held, the base is provided with a lid, which can be snapped onto the base body, and which with rectangular insertion openings for the relay pins is provided.
  • the length of the jaws is less than the distance between the pit floor and the lid, so that the used clamps have scope.
  • a disadvantage of such a base is that the Insert the base into a circuit board due to the Insertion resistance on the terminal force over the Jaws are transferred to the lid. Hence the Clamping jaws when inserting the base into a board like on the lid and can subsequently be touched by this touch be unable to move.
  • Disadvantage of the Terminal is also that the electrical load asymmetrical and therefore the heat distribution in an under Current load standing terminal is unequal. Can continue at least as long as the clamp is not through a base is protected, the connector by inserting a Object between the jaws are deformed. In the As a result, the clamping force of the clamp is reduced. For a stable electrical contact between terminals and However, a terminal needs a specific pin surface minimal clamping pressure.
  • the object of the invention is a socket clamp and to create a base in which the disadvantages mentioned are overcome.
  • the mobility of the contact flags should be included Security can be guaranteed.
  • the clamp should be in front of and during insertion into the base before bending and be protected from damage. It should continue less be sensitive to thermal energy occurring than that State of the art mentioned.
  • Another object of the invention is the possibility of simple and inexpensive Manufacture of the clamp and the base.
  • a Protective tab which is arranged on the connecting part and from the central area in the same direction as that Contact flags extends and with their free end over the free ends of the contact tabs extends.
  • This so-called protective tab fulfills several Functions. Firstly, by adding the Protective strap the mass and weight of the clamp by about 30% enlarged so that a larger amount of heat from the clamp can be included. Their dimensions are only slightly larger. This is e.g. when immersing the male contact part in the liquid solder advantageous because the This makes the clamp less sensitive to the immersion time is. On the other hand, by protruding the protective tab Protection of the latter beyond the contact flags and reached during the assembly of the base. For the third thanks to the protrusion of the protective flap, the force e.g. due to the insertion resistance when inserting the Socket in a board acts on the clamp, not over the Clamping tabs, but over the insensitive protective tab transferred to the base body.
  • the clamp since the protective tab is not bent during production are needed and protrude from the contact springs, from one Sheet metal strip are manufactured and only after the clamp has been manufactured the clamp by separating the free end of the protective tab and Ribbon can be detached from the ribbon. Thanks to this tab, therefore the clamp with a symmetrically arranged male Contact part are manufactured.
  • the protective tab advantageously has a free end Width, which the distance between the two jaws in Central area corresponds. This allows the clamp to be Terminal chamber with parallel walls can be inserted and is over the longest possible length by the Interaction of the chamber wall with the protective flap as well guided in the central area of the clamp with the clamping tabs. Hence the possible deviation of the clamp from its Ideal position with regard to the terminal chamber minimal.
  • the male contact part e.g. one pin, one Solder connection lug, a plug connection lug or the like
  • the male contact part attaches to the U-shaped central area and twice in the opposite direction by about 90 degrees across Thru-axis direction is bent, then the male sets Contact part with advantage on the connector.
  • the Start at the connector in contrast to the known one Starting at one of the clamping tabs is the current flow distributed more evenly over the two contact flags. Therefore the heat development in the clamping tabs is more even. Thanks to the symmetry of the current and heat load, the Clamp performance increases because of a smaller local Stress occurs. In addition, the heat is dissipated the symmetrically arranged protective tab better.
  • Another Advantage of the symmetrical arrangement of the male Contact part is that the clamping tabs and the male Contact part bent at the same time in one operation can be. This is made possible by the protective tab which is expediently still with the Sheet metal strip from which the clamp is made, connected is.
  • the arrangement of the male also has an effect Contact part on the connector positive on the rigidity of the connector.
  • To be as high as possible To achieve bending stiffness of the connecting piece, expediently runs the first bending edge of the male contact part practically over the entire width of the Connector. This stiffens the bending edge Connector across its entire width, making the undesirable additional spring action of the connector is largely canceled.
  • the outline of the clamp in is advantageous
  • the maximum direction of insertion is with a rotation of the outline 180 degrees again congruent.
  • the outline is preferred rectangular or clearly shaped in terms of orientation. This allows the clamp to be in at most two orientations the base body can be used. With both orientations the clamping direction is correct. Due to this outline shape can align the terminal correctly with regard to its alignment the female contact part inserted into the base be what, for example, in a round or square outline is not possible.
  • This larger dimension corresponds to the distance between the two opposite Chamber walls with openings for insertion on the one hand a pin in the female contact part and on the other hand for the penetration of the base wall with the male Contact part of the terminal.
  • the remaining external dimensions of the female contact part the other two inner dimensions of the Chamber.
  • the width of the protective tab or Distance between the clamping tabs in the base area plus the Material thickness of the two clamping tabs corresponds advantageously the one inside dimension of the terminal chamber. As a result, the clamping tabs in the central area are covered by the Chamber wall prevented from spreading.
  • the walls are advantageous double between the chambers, so that on Fastener formed ribs after assembling from the base body and the closing part into the gaps reach between the double walls. Thereby the air and creepage distances between the individual Clamps inside the base increased and the closing part is stiffened by the cross-shaped ribs.
  • the closing part on the side of the Male contact parts arranged so that the terminals with the female end first are inserted into the terminal chambers and, if necessary by a robot, on the male Contact part can be held.
  • Such a base can be used as a base for relays, sensors, Display elements or electronic circuits etc. serve. It can be plugged in with the pins of the terminals be, but also e.g. with tabs and / or clamps on Base body or be equipped on the closing part, so that the plastic part can be screwed on somewhere, glued on or can be clamped. If the base does not have the Legs of the terminals, but on the plastic part attached, so the male connectors are usually expediently as solder connection lugs, Plug connection lugs, screw connection lugs etc. educated.
  • the Clamps can also be guided to the point on the belt, where they should be inserted into the base. There can Clamp on the male contact part by a machine can be caught when it is detached from the tape and are guaranteed to be in the correct position Terminal chamber are introduced. This enables transports of loose clamps can be avoided. It can be a Saved shakers and damage to the clamp before Use largely avoided.
