Definitions
- the present invention relates to a spring intended in particular for making an electrical connection.
- a connection spring is found for example in a connection terminal for conductor electric.
- connection terminals It is known to use springs to maintain the end of a stripped conductor against a current supply rail in a connection terminal.
- Documents DE-37 27 091 or DE-42 37 733 describe for example connection terminals of this type. These documents contain a connection spring produced in a flat elastic material having a general shape of a loop.
- the connection spring has a support branch intended to come to rest against the current supply rail and a pinch branch folded back from the rear part of the spring, extending substantially transversely to the current supply rail, as well as an elastic arc connecting the rear part and the supporting branch together from the rear.
- a device of this type can also be used to carry out a self-stripping connection of an electric cable.
- the spring is used to accumulate the energy necessary to strip a cable electric and come to wedge it in a connection slot, and to restore this energy when the time comes.
- Such a spring has at its pinch branch a window through which the current supply rail passes and which receives also the stripped end of a conductor to be connected.
- This driver is kept in abutment on the current supply rail, on the opposite face to that against which the support branch rests.
- this window has a rectangular shape. Its width, which influences the maximum connectable section, is constant. In addition, this width is limited by the mechanical strength of the spring. Indeed, the widening of the window weakens the pinch branch of this spring.
- the object of the present invention is to provide a spring for connection which, for a space identical to that of the springs of prior art, allows to connect a conductor of larger diameter important while retaining good mechanical properties.
- the invention provides a spring, in particular a spring connection, made from an elastic blade folded so as to have a supporting branch and a movable branch connected by an arc elastic to the supporting branch, an opening being made in the branch mobile near its free end and being intended to receive a end of conductor to be connected.
- the opening has transversely a variable width, this width being greater on the end side free from the mobile branch.
- the opening has a elongated trapezoidal shape.
- the large base of the trapezium is is of course on the side of the free end of the movable branch of the spring.
- the opening has two zones of different widths connected by a connecting area.
- the area of connection has an arcuate outline and is arranged so that a conductor corresponding to the maximum connectable diameter comes follow the outline of the bonding area when it is introduced into the opening. This variant of embodiment makes it possible to optimize the resistance mechanical spring at its movable branch.
- Figure 1 shows a spring 2 according to the invention. This spring is intended to make an electrical connection in a terminal connection.
- the spring 2 has a loop shape and has a fixed support branch 4 and a movable branch 6.
- An elastic arc 8 connects the two branches 4 and 6 forming a loop.
- Spring 2 is produced in a strip of flat material, for example a strip of steel sheet.
- the fixed branch 4 is intended to come into abutment against a part electrically conductive fixed link such as the supply rail current 10 shown in the drawing.
- the support branch 4 follows the shape of the supply rail of current 10.
- another form of support branch or rail power supply is possible.
- the movable branch 6 has a bent shape. It involves a first substantially flat portion 12, a bend 14 and a second part 16.
- the first flat part of the movable branch 6 is substantially perpendicular to the support branch 4.
- An opening 18 is done in this first part. It is intended to allow the passage of the end of a conductor to be connected as well as the rail current supply 10.
- the elbow 14 folds the movable branch at an angle of about 90 °, the second part 16 of the movable branch 6 connects the elbow 14 with an elastic arc 8.
- the present invention relates in particular to the form of the opening 18.
- this opening has an elongated trapezoid shape.
- the two basics of the trapezoid are perpendicular to the strip of material used for make spring 2.
- the large base is located on the side of the free end of the second part 12 of the mobile branch 6.
- FIG. 3 shows the spring according to the invention in the position of rest. The large base of the opening 18 is then in abutment against the rail current supply 10.
- Figure 4 shows this spring when conductor 20 of maximum connectable diameter is connected. We see on FIG. 4 that the spring 2 keeps the conductor 20 in abutment against the current supply rail 10, as conventionally carried out with a connection spring.
- Figures 5 and 6 show a second embodiment of the spring 2.
- the opening 18 has on the side of the free end of the first part 12 of the movable branch 6 a relatively wide large corresponding to the maximum diameter of a cable that can be connected in this spring 2.
- the opening 18 On the side opposite the free end of the first part 12 of the movable branch 6, the opening 18 has a lesser width. This other end is substantially shaped rectangular.
- the connection of the wider area of the opening 18 with the narrower area of this opening is made by arcs of a circle whose radius corresponds to half the maximum diameter of a conductor which can be connected. This connection area is arranged so that when a conductor of maximum diameter is introduced into the opening 18, they conform to the shape of these connecting zones.
- Figure 6 shows the case of connecting a maximum size conductor.
