Definitions
- the present invention relates to a conductor clamping device for equipping a low voltage device clamping terminal.
- a conductor clamping device for equipping a low voltage device clamping terminal.
- a tool is usually used to move the clamping spring away.
- the stiffness of the resilient clamping spring must be adapted to allow both to keep the conductor in contact with the connecting bar and to introduce the conductor against the elastic force.
- a clamping terminal comprising a device in which the bar is fixed or held in position by clamping, the device comprising several different constituent elements are used, in particular elements constituting a driver's accommodation cage and a spring.
- the width of the elastic member is constrained by the dimensions of the cage. Consequently, it is necessary to obtain the desired stiffness of the spring in an acceptable space, to use different materials for the elastic member and for the cage.
- the spring can not have the desired stiffness.
- the present invention aims to provide a clamping device for a clamping terminal whose assembly and manufacture are simplified, while providing the desired stiffness characteristics.
- the present invention relates to a clamping device for a connection terminal by clamping a conductive wire to a conductive connection bar, comprising: a portion forming a conductor housing, comprising at least one upward opening intended to receive at least one conductive wire to be connected, as well as the conductive connection bar,
- a clamping spring for holding in position the conductor wire introduced into the housing portion against the connecting bar by applying an elastic force
- the clamping spring having a first connecting leg formed by an extension of a portion of a wall delimiting the housing portion, connected by a bend to a second clamping leg having a free clamping end, characterized in that the bend between the first connecting branch and the second clamping branch is located at least partly from the opposite side to the opening of the housing, relative to the plane of the portion of a wall defining the housing portion of which the first connecting leg forms the extension, and in that the opening for receiving at least one conductive wire is located on the opposite side of the wall portion defining the housing portion relative to the clamping leg.
- the housing portion comprises a housing housing having a side wall defining at least one opening upwards.
- the housing portion comprises a bearing portion located in the extension of a second wall portion of the cage opposite to the first wall portion whose extension forms the clamping spring.
- an opening is formed in the support portion.
- the free end of the tightening leg of the clamping spring is located in the opening in the rest position of the spring.
- the clamping spring comprises at least one portion having a width greater than that of the cage.
- the spring comprises at least two portions of different widths.
- the device is formed in one piece, by folding.
- the device is made from a cut material comprising a first strip intended to form the housing portion and a second portion substantially transverse to the first intended to form the spring by bending and folding.
- a cage is formed by folding a strip of material having two portions of complementary shapes intended to be housed one inside the other.
- the present invention also relates to a low voltage device comprising a clamping device as described above.
- FIG. 1 is a perspective view of a clamping device according to one embodiment.
- FIG. 2 is a front view of the element of FIG. 1
- Figure 3 is a sectional view of the element of Figure 1, a connecting bar being inserted into the housing portion.
- Figure 4 is a sectional view of the element of Figure 1, a connecting bar being inserted into the housing portion, a conductor being connected.
- Figure 5 is a front view of the profile of a cut plate for forming the device of Figure 1 after folding.
- FIGS. 1 to 6 are perspective views of the device of Figure 1 and a portion of low voltage apparatus for receiving it.
- a clamping device 2 for a connection terminal by clamping a conductive wire 3 to a conductive connection strip 4 comprises a housing part 5 intended to receive the conductor to connect 3 comprising: - a cage 6 having a side wall of substantially rectangular section open upwards, - A support portion 7 protruding from the cage, in the extension thereof.
- the support portion includes:
- the housing portion 5 is also intended to receive the connecting bar 4, which is arranged against the first flat bearing face 8 of the wall 6 of the housing part 5.
- An opening 12 is formed in the bearing face 8 at the level of the bearing portion 7.
- the device also comprises a clamping spring 13 intended to maintain in position against its elastic force a conductor 3 introduced into the housing part 5.
- the clamping spring 13 is constituted by an extension of a second plane face 14 of the wall of the housing part 5, located opposite the first planar face 8.
- This clamping spring 13 comprises: a first connecting branch connected by a first end to the second face of the housing part 5, forming the extension thereof, a bend 16 connected to the second end of the housing; first connecting branch 15, and - a second clamping branch 17, connected to the bend 16 by its first end and having a second free end 18 clamping.
- the bend 16 between the first connecting branch and the second clamping branch is located on the opposite side to the opening of the housing, with respect to the plane A of the second plane face 14.
- the opening of the housing portion 5 upwards, intended to receive at least one conductive wire, is located on the opposite side of the second face 14, with respect to the clamping branch 17.
- the clamping end 18 is intended to hold in position a conductor 3 introduced into the housing part 5 against the connecting bar 4.
- This arrangement makes it possible to increase the prestressing of the spring with respect to the position occupied when the bar is in position in the housing, the inclination of the clamping leg of the spring relative to the bar serving as a bearing surface being increased. Thus, the stiffness of the spring is increased.
- the clamping end 18 of the spring is located in the rest position of the spring in the opening 12 of the bearing portion 7.
- clamping spring comprises a boss 19 directed towards the outside of the spring 13, and making it possible to form a stop for the screwdriver or other tool intended to push the spring in order to pull out the connected conductor 3 by means of device 2.
- the clamping branch 17 of the spring comprises two portions 20 and 22 separated by the boss 19, the second portion 22 located near the end 18 having on its end portion a restricted width for accommodating the clamping end 18 between the side faces 9, 10 of the bearing portion 7.
- the spring is formed in the extension of a face of the housing portion, and thus that the spring, with the exception of the end portion, is located outside the housing portion, allows to make a spring whose width is greater, because it is not limited by the width of the housing portion. It is thus easily possible to obtain the desired stiffness for the spring, without using a specific material.
- the device 2 is made in one piece from a plate-shaped material.
- the portion constituting the cage is formed of a strip 25 having at each of its ends respectively a trapezoid-shaped lug 26 and a complementary shaped housing 27, in order to form, by folding, a closure by complementarity of form.
- FIG. 6 represents a part of the insulating body of a low-voltage device 28, comprising a housing 29 intended to receive a device 2, as well as a connecting bar 4.
- the body of the apparatus comprises a conductor insertion opening 30 and an insertion opening 32 of a tool 33, used to remove the conductor from the terminal thus formed.
- the invention is not limited to the preferred embodiment described above, by way of non-limiting examples; it encompasses all the variants in the context of the claims below.
