Definitions
- the invention relates to a contact element for pressing into a hole in a circuit board according to the preamble of claim 1.
- Press-in technology is a method for connecting electrical contacts to circuit boards without soldering.
- the press-in contact has a deformable (flexible) or solid press-in zone.
- the press-in zone is oversized compared to the corresponding hole in the PCB, which is coated with copper.
- the electrical contact between the press-in pin and the LP is made by pressing the pin into the sleeve with mechanical force, i.e. So no solder or other aids are used.
- the normal force required to maintain a stable and reliable connection is created by the elastic deformation of the press-in zone (flexible pin) or the LP (solid pin).
- the press-in zone has an elastically deformable area. Due to the deformation of the press-in zone in the pressed-in state, a normal force is exerted on the surrounding copper sleeve, which determines the holding force of the pin in the sleeve.
- the simplest possible form of an elastic press-in zone is the so-called needle-eye zone; i.e. the shape of the eye of a needle.
- the press-in legs have a continuous concave curvature on the outside. This geometry leads to a very uneven force distribution seen in the pressed-in state over the length of the press-in zone. High forces arise in a narrowly defined area in the middle of the press-in zone, while hardly increased forces occur above and below it and the press-in legs do not lie against the sleeve over a wide area.
- a modified needle-eye zone is known from published patent application DE 197 26 759 A1. This zone has a modified inner contour, which should lead to a more even distribution of force when pressed in.
- a contact element can already be gathered from the generic DE 19934709 in which the deformable area has a front and a rear area and the two areas each have a closed opening, which are separated by a transverse web running transversely to the direction of insertion of the contact element, i.e. the legs of this press-in zone are separated by the openings, but in turn connected by the crossbar.
- the contact element has a constriction in the region of the crosspiece and is designed to be narrower in the front region, as a result of which the thigh outer edges lying against the hole edge likewise do not touch the hole sufficiently over a large area and there is a strongly locally fluctuating uneven load.
- the crossbar runs perpendicular to the direction of insertion and can hardly be resilient.
- the object of the invention is therefore to present a contact element which enables the most secure and uniform fastening and contacting possible in the opening of the printed circuit board.
- This object is solved by the features of claim 1.
- Advantageous further developments can be found in the subclaims.
- the contact element has a front and a rear area, each with a closed opening, which are separated by a crosspiece to the direction of insertion of the contact element, ie the contact element has at least two legs, which are separated in the deformable area by the two openings and by the Crossbar are connected to each other.
- the crossbar divides the opening typical of needle-eye zones into two parts.
- the crossbar runs at least in a partial area with an acute angle between 5 and 85 degrees to the direction of insertion, so that when the legs are pressed in transversely to the direction of insertion, due to the acute angle, the crossbar is subjected to a bending load in this area and thus to a uniform increase in Drag comes.
- This crossbar supports the legs from the outside and thus ensures a uniform load due to its bending elastic deformation, in particular in the case of legs which are configured in the deformable area on their outer sides lying against the edge of the opening essentially parallel.
- the crosspiece is curved in a wave-shaped manner in the insertion direction, that is to say it has curved regions in the insertion direction or in a plane in which the insertion direction also lies, whereas in the prior art crosspieces were bent at most into the plane perpendicular to the insertion direction.
- transition area between cross bar and legs is approximately perpendicular to the direction of insertion and the central area of the cross bar is inclined accordingly to the direction of insertion, so that the bending load is not directly at the transition point between the leg and cross bar.
- the contact element preferably has a plane in which both the contact element with the transverse web and the direction of insertion lie and the contact element is symmetrical with respect to this plane.
- the thickness of the crossbar i.e. its dimensions in the direction of insertion as well as the degree of the acute angle and the shape of the crossbar, are strongly dependent on the application a and must be adapted to the requirements. Ultimately, an optimum can be found for a given hole diameter, where a cross bar that is too thin cannot generate sufficient counterforce and the legs therefore do not have sufficient contact pressure on the wall of the hole in the middle of the deformable region, while a cross bar that is too thick generate a counter force that is too strong and thus the legs are pressed sufficiently only in the middle of the deformable area.
- the aim is to ensure that the contact pressure is as large and uniform as possible, which enables high mechanical strength between the contact element and the printed circuit board and is also highly flow-conductive.
- Fig.1 first embodiment of the contact element in two views
- Fig. 2 second embodiment of the contact element in two views.
- Fig. 1 shows a contact element for pressing into a hole in a printed circuit board, the contact element having a pin-shaped press-in zone with an insertion region (L1) and a deformable region (L2, L3) adjoining it .
- the deformable area has a width (D 1) that is greater than the diameter of the hole, and the insertion area has a width (D2) that is smaller than the diameter of the hole, so that the contact element with the insertion area initially without effort in The direction of insertion F can be inserted and is thereby automatically aligned in the hole due to the oblique profile of the legs in the transition area L2.
- the deformable area has a front (1) and a rear area (2), both of which have a closed opening, which are separated by a crosspiece (3).
- the legs (4, 4a) are thus separated in the deformable area by an elongated hole which is divided into two openings by a crossbar connecting the legs.
- the crosspiece extends at least in a partial area with an acute angle () between 5 and 85 degrees to the insertion direction F, in this example approximately 45 degrees. This inclination leads to the fact that when the contact element is pressed into the opening of the printed circuit board and the legs 4, 4a are pressed together, the transverse web is subjected to bending elasticity in the deformable region.
- the legs are configured in the deformable region over the length L3 essentially parallel to one another and to the wall of the opening. When pressed into the The crossbar acts on the center of the deformable area and allows the legs to be pressed more evenly over the entire length L3.
- the two legs (4, 4a) of the contact element are thus separated in the deformable area by the two openings and in turn connected to one another by the crossbar, the crossbar having an approximately perpendicular transition area to the legs at an angle ⁇ , preferably between 75 and 90 degrees and an intermediate sloping central area with an acute angle between 5 and 85, for example approx. 45 degrees to the direction of insertion.
- the transitions from the crosspiece to the two legs can be formed at a height with respect to the insertion direction, as shown in FIG. 2, or offset by a distance, as shown in FIG. 1.
- the crosspiece (3) is preferably curved in a wave shape.
- the cross piece 3 according to FIG. 1 is essentially corrugated in the insertion direction (F) in such a way that the central region extends at an acute angle obliquely to the insertion direction F and with the edge regions continuously leads to a vertical transition region to the legs 4, 4a , This results in different transition areas to the legs on the two legs in the insertion direction F with distance from the tip.
- the crossbar 3 according to FIG. 2 on the other hand, has a V-shape corrugated in the insertion direction (F), at least in the central region. Both parts of the V-shape have an acute angle to the insertion direction F.
- the crossbar 3 according to FIG. 2 also has the advantage that it is designed symmetrically to the direction of insertion and so the transitions to the crossbar are at the same height.
- the contact element also preferably has a stop on the side facing away from the insertion area, which limits the insertable length L of the contact element.
- the contact element is designed to be flat overall, that is to say it has a plane E in which both the contact element with the transverse web and the insertion direction F lie.
- This level E corresponds to the drawing level in Figures 1 a and 2a.
- the contact element is symmetrical with respect to this plane, as the transverse views 1b and 2b show.
