Definitions

  • the invention relates to a clamping body component for connecting an electrical conductor to a printed circuit board according to the preamble of claim 1.
  • Such a clamp body component has at least one contact element which is integrally formed (for example punched out) from the material of the clamp body component and which serves for the electrical and, if appropriate, mechanical contacting of a printed circuit board, and an opening formed during the production (molding) of the contact element.
  • a clamping member component in the form of a one-piece, made of a piece of spring ribbon material, loop-shaped electrical spring clamp which has a clamping leg and a plant leg. At the plant legs while means for electrical and mechanical connection of the spring terminal are formed with a circuit board. These means comprise a punched out of the plant leg of the spring terminal contact element in the form of a solder pin, which is angled from the plant leg. When punching out the solder pin from the spring terminal a corresponding with the contour of the solder pin opening (in particular in the form of a passage opening) is formed in the plant leg. If such a clamp body component is supplied as bulk material for further processing, snagging of clamp body components can occur in that the solder pin of a clamp body component penetrates into the corresponding opening in another clamp body component.
  • a sprag member is described in the form of a current bar, which forms a multi-part spring terminal together with an associated clamping spring and a clamping spring and the current bar surrounded housing.
  • At a first leg of the current bar are substantially perpendicular from two pins, which are integrally formed on each one end of said current bar leg.
  • the invention is based on the problem of further improving a sprag component of the aforementioned type.
  • the dimensions and the opening cross-section of the opening resulting in the clamping body component do not correspond to the dimensions of the contact element produced under the original formation of that opening, but are reduced in comparison, so that the contact element of a clamping body component that the contact element of another (identical) clamping body component (with identical dimensions) associated opening can not pass. A snagging of the sprag components is thereby avoided.
  • the clamping body component on the boundary wall of the opening has at least one formation which reduces the cross section of the opening.
  • a corresponding shaping can be provided on at least one of two opposite wall sections of the boundary wall of the opening to be reduced in cross-section (thus also on both wall sections), e.g. such that the opening tapers in the region of a respective shaping.
  • a deformation of the clamping body component in the region of the opening, in order to reduce the cross section of the opening formed in this case after the production of the contact element, can be effected in particular by embossing or pressing.
  • an insertion element is inserted into the opening to reduce the opening cross-section.
  • This may be e.g. a substantially rigid (can be pressed into the opening) insert or act a spring-elastic component or to a curable, pasty filling material, such as an adhesive.
  • the contact element is elongate (designed as a contact pin, eg soldering pin) and the corresponding opening in the clamping body component is accordingly also elongated (slot-shaped).
  • the (slot-shaped) opening limiting longitudinal sides of the boundary wall is formed such that the opening is narrowed in the region of a molding.
  • the contact element and the opening corresponding thereto may be formed on a base portion of the clamping body component which (via the contact element) the preparation of a connection with a circuit board is used.
  • the clamp body member may further comprise a clamping portion for clamping a conductor to be connected to the printed circuit board.
  • a sprag component, z. B. in the form of a current bar can be used, which forms one of several components of a multi-part clamp body, in particular in the form of a spring clamp.

  • Fig. 3 is a sectional view of the first clamping body component in the form of a
  • FIGS. 1 and 2 shows a current bar according to FIGS. 1 and 2 together with slides for forming a shape on the current bar;
  • FIG. 4B shows the current bar of FIG. 4A after formation of the shaping
  • FIG. 5 shows a current bar according to Figure 1 and 2 with an insert for at least partially closing an opening of the current bar.
  • FIG. 1 shows a metallic first clamping body component in the form of a current bar 1 (designed as a pressure piece) and a second clamping body component in the form of a clamping spring 2, which in the assembled state, as shown in FIG. 2, form a clamping body in the form of a spring-loaded terminal.

  • the contact element 140 can be inserted into an opening provided therefor of a printed circuit board and connected by soldering to make an electrical contact with this.
  • the contact element 140 has been formed out of the base section 10 of the current bar 1 to form an opening 14 (through-opening). This can be done for example by punching or Ausscheren of the contact element 140 of the material of the base portion 10, so that it is at the current bar 1 is a stamped and bent part. Due to the design of the contact element 140 as an elongate contact pin, the corresponding opening 14 formed in the production of the contact element 140 in the base section 10 of the current bar 1 is also elongate (formed as a slot-shaped opening).
  • a projection 13 is arranged (integrally formed). Of the Projection 13 is spaced from the (slot-shaped) opening 14 in the base portion 10, in the embodiment along the longitudinal direction of the opening 14. The projection 13 faces from the base portion 10 in the direction of the opposite clamping portion 15 of the current bar. 1
  • the two sections 1 1, 12 of the base portion 10 are in this case angled to form an obtuse angle to each other.
  • the clamping portion 15 of the current bar 1 defines a clamping surface 16 which faces the base portion 10 of the current bar 1 in the embodiment and on which (by means of the clamping spring 2) an electrical conductor can be clamped to connect via the contact element 140 of the current bar 1 with a circuit board is.
  • the clamping surface 16 is provided with a plurality of transverse recesses 16a, in the embodiment in the form of beads.
  • the second clamping body in the form of a clamping spring 2 is configured such that it can be arranged in the space surrounded by the (C-shaped) first clamping body in the form of the current bar 1, as shown in FIG.
  • the clamping spring 2 is supported on the one hand with a contact portion 20 (in the form of a support leg) on the base portion 10 of the current bar 1 and on the other hand with a clamping portion 25 (in the form of a clamping leg) on the clamping surface 16 of the current bar 1 a.
  • the clamping spring 2 is present under bias on or taken in the current bar 1, which can be achieved by a corresponding dimensioning of the clamping spring 2 relative to the dimensions of the space surrounded by the current bar 1 space.
  • the abutment portion 20 of the clamping spring 2 has two sections 21, 22, which are each associated with one of the two sections 1 1, 12 of the base section 10 of the current bar 1.
  • the two sections 21, 22 of the clamping spring 2 are - as well as the associated sections 1 1, 12 of the current bar 1 - angled to form an obtuse angle to each other, so that when the arrangement of the clamping spring 2 within the space surrounded by the current bar 1 each of the two sections 21, 22 of the contact portion 20 of the clamping spring 2 is flat against a portion 1 1 and 12 of the base portion 10 of the current bar 1.
  • the Clamping portion 25 of the clamping spring 2 has for this purpose at its free end 26 a clamping portion 26 a, in the embodiment in the form of a clamping edge, which presses against the clamping surface 16 under bias.
  • the abutment portion 20 and the clamping portion 25 of the clamping spring 2 are connected to each other via a connecting portion 28 such that the clamping portion 25 (at an acute angle) inclined to the base portion 20 extends.
  • the clamping spring 2 in the area enclosed by the current bar 1 space is therefore on the one hand, as described, the contact portion 20 flat on the base portion 10 of the pressure beam 1, while the clamping portion 25 at its free end 26 via the clamping portion 26a in the form of a clamping edge the clamping surface 16 of the current bar 1 acts.
  • the clamping spring 2 is dimensioned such that it is slightly compressed between the clamping portion 15 and the base portion 10 of the current bar 1, whereby the bias voltage is generated, which holds the abutment portion 20 of the clamping spring 2 and the base portion 10 of the current bar 1 in Appendix.
  • the clamping spring 2 and the current bar 1 are in the region of the clamping spring-side abutment portion 20 and the current bar side base portion 10 additionally positively engaged to ensure a reliable, permanent fixation under the action of the bias generated at the clamping spring 2.
  • a (circular) mounting opening 23 is formed in the first section 21 of the contact section 20 of the clamping spring 2, which rests on the first section 1 1 of the base portion 10 of the current bar 1. In this engages the at the base portion 10 of the current bar 1, more precisely at the first portion 1 1, provided (cylindrical) projection 13, when the clamping spring 2, as shown in Figure 2, intended use in the current bar 1 is arranged.
  • the engagement is advantageously substantially free of play.
  • a projection in the form of a spring tongue 24 is arranged on the contact section 20 of the clamping spring 2, more precisely on the second section 22, which engages in the opening 14 formed in the base section 10 of the current bar 1 when the contact element 140 is formed.

  • this opening 14 would have a width b throughout which corresponds to the width b of the contact element 140 produced to form the opening 14 - which just causes the above-described problem of hooking the current bars 1.
  • the cross section of the opening 14 is reduced by an embossing process (carried out after the production of the contact element 140).
  • an embossing punch has acted on the inner surface 10a of the base section 10 in the region of the opening 14 there.
  • a recess 3 is formed on both sides of the opening 14 on the inner surface 10a and the material removed when the recess is formed has been displaced against wall sections 14a, 14b of the lateral boundary wall of the opening 14 to produce a corresponding shaping or deformation 4a, 4b.
  • the wall sections 14a, 14b taper along the wall thickness d, namely from the outer surface 10b of the base section 10 to the inner surface 10a of the wall Base section 10.
  • the reduction of the cross section of the opening 14 in the base portion 10 of the current bar 1 does not necessarily have to be done by embossing, but other suitable forming or deformation techniques can be used for this purpose.
  • pressing by means of slides (bending punches) acting laterally (in the opposite direction) on the current bar 1 is used as a deformation technique in order to reduce the cross section of the opening 14 in the base section 10 of the current bar 1 or, more precisely, the opening 14 by partially closing the lateral wall sections 14a, 14b.
  • a respective lateral wall section 14a, 14b of the boundary wall of the opening 14 (on which each one of the slides S1, S2 has acted) has a formation 5a, 5b pointing in the direction of the opposite wall section 14b, 14a.
  • the formation of the formations 5a, 5b can be carried out in a simple manner directly in the punching and bending tool, in which the current bar 1 is produced by bending in its shape shown in the figures and by punching out of the contact element 140. For this purpose, only correspondingly movable slides S1, S2 need to be provided on or in that tool.
  • the final deformation of the current bar 1 does not have to, as shown in the exemplary embodiment, lead to a material deformation being present on two opposite lateral wall sections 14a, 14b of the boundary wall of the opening 14. Rather, it is basically sufficient to deform the material of the base section 10 only in the region of a lateral wall section 14a or 14b of the boundary wall of the opening 14 in such a way that the cross section of the opening 14 is thereby reduced. It is important that the material of the base portion 10 of the current bar 1 is formed in the region of the opening 14 (formed when the contact element 140 is formed) in order to reduce the opening cross-section and to prevent the contact element of a structurally identical current bar from penetrating.
  • the opening 14 in the base section 10 of the current bar 1 is at least partially closed by insertion of an insertion element 6 and thus its Cross-section such (possibly down to zero) reduces that the penetration of the contact element of another, identical current bar is prevented.
  • the insertion element 6 may be configured to be (as an insert) such that it is to be pressed into the opening 14 to form a press fit; or it may be fixed thereto by a bonding agent, in particular an adhesive.
  • a filling compound to be introduced in pasty form, such as an adhesive can be used as the insertion element in order to reduce the opening cross section.
