Definitions

  • the moveable contact has an end plate that falls into recesses in the first and second surface and which prevents the moveable contact to be retracted from between the first end and the first further end.
  • the moveable contact is mounted on the moveable contact with a bolt, the head of which protrudes between the first surface and the second surface.
  • a plug contact for connecting a first contact to a second contact, comprising a first contact finger comprising a first surface, a second contact finger comprising a second surface, the second surface facing the first surface;
  • the inventors realised that with a current flowing through the first contact finger and the second contact finger in the same direction, the first contact finger and the second contact finger attract each other and that the smaller the distance between the first contact finger and the second contact finger, the larger the attraction. At the ends the distance obviously needs to be large enough to clamp the first contact and the second contact between them. Because the distance in the area between the first supply end and the first load end is smaller than at the first supply end and the first load end, the attractive force between the first contact finger and the second contact finger is larger than if it would have had the same distance at the first supply end and the first load end or a larger distance, such as in the prior art. Therefore, as the attractive force is larger, the chances that the plug contact will explode are smaller.
  • a plug contact according to the first embodiment comprising a resilient member arranged to force the first surface and the second surface against each other at the middle area in absence of the first contact and the second contact.
  • a plug contact according to the first or second embodiment, arranged to retractably receive the first contact and the second contact.
  • the plug contact being arranged such that the first contact and the second contact may be received and retracted in any order.
  • the first contact and the second contact can be received and retracted in any order, the contact plug does not have to be clamped on the first or the second contact before the other contact is received.
  • This is advantageous, for instance when used in a switchgear cabinet where the plug contact may be brought into contact with a bus bar (say the first contact) first and with a drawer (with say the second contact) later.
  • the plug contact is welded on the contact of the drawer, the other contact may be retracted first.
  • a plug contact according to any of the preceding embodiments, wherein the first contact finger and the second contact finger are arranged to in use be laterally displaced with respect to each other when in use both the first contact and the second contact are received.
  • Figure 2 depicts a plug contact according to the invention in with a first contact and a second contact are plugged
  • a first supply end (17) of the first surface (15) and a second supply end (18) of the second surface (16) form a fork that is aligned with the distribution bus bar (7).
  • the distribution bus bar (7) is received in the space between the first supply end (17) and the second supply end (18).
  • the first supply end (17) and the second supply end (18) are biased against the distribution bus bar (7) by a resilient member (12), here a spring (12), to make an electrically conducting contact and thereby clamping the distribution bus bar (7).
  • the legs (30) extend in the z-direction and clamp around the first contact finger (13) and the second contact finger (14).
  • the legs (30) have equal width in the y-direction.
  • the legs (30) are curved such that the contact surface with the first contact finger (13) and the second contact finger (14) is small, corresponding to a high local pressure.
  • the curvature is such that one of the legs (30) makes contact to the first contact finger (13) along a line in the y-direction, i.e. parallel to the direction in which the first contact finger (13) is elongated.
  • the point where the line intersects the plane of symmetry perpendicular to the y-direction is the centre of the resilient force (32).
  • the first surface (15) also has a first load end (19) that is at the other side of the elongated first contact finger (13).
  • the second surface (16) also has a second load end (20) that is at the other side of the elongated second contact finger (14).
  • the distance between the first supply contact area (24) and the centre of the resilient force (32) is smaller than the distance between the first load contact area (26) and the centre of the resilient force (32) by a factor f.
  • the factor f for instance is smaller than 1/3 or 1/4.
  • the middle area (22) and the further middle area (23) area abutting i.e. the distance between the first surface (15) and the second surface (16) at the middle area (22) is zero.

Abstract

L'invention concerne un plot (10) destiné à connecter un premier contact (7) à un second contact (21). Le plot comprend un premier doigt (13) de contact contenant une première surface (15), un second doigt (14) de contact contenant une seconde surface (16), la seconde surface faisant face à la première surface (15); le plot (10) étant agencé pour recevoir le premier contact (7) entre une première extrémité d'alimentation (17) de la première surface (15) et une seconde extrémité d'alimentation (18) de la seconde surface (16) et agencé pour recevoir le second contact (21) entre une première extrémité de charge (19) de la première surface (15) et une seconde extrémité de charge (20) de la seconde surface (16), le premier doigt (13) de contact et le second doigt (14) de contact étant disposés pour connecter le premier contact (7) au second contact (21), caractérisé en ce que la distance entre la première surface (15) et la seconde surface (16) est plus petite au niveau d'une zone centrale (22) entre la première extrémité d'alimentation (17) et la première extrémité de charge (19) qu'au niveau de la première extrémité d'alimentation (17) et la première extrémité de charge (19).
