Definitions
- the invention relates to a contact contact type electric contact device with a high current rating
- FIG. 1 A first known example of embodiment of a contact finger type electrical contact between a first part 10 and a second part 11 is illustrated in FIG. 1.
- the electrical contact is made by a contact pad 12 applied to a conducting surface of the second part 11 following a contact zone 13, metal blades 14 and a flexible rod 15. These blades which are connected to a mechanical and electrical connection element 16 to the first part 10 ensure the passage of current between the contact pad 12 and this element 16.
- the flexible rod 15 provides a spring function and makes it possible to achieve the contact force without ensuring the passage of electric current.
- a second known example of producing a contact-type electrical contact consists of a monoblock contact whose three functions of electrical contact, electrical current flow and spring described above are made in one element obtained for example by machining or stamping.
- This second example constitutes an economic embodiment.
- a difficulty remains because of the joint dimensioning of the current flow function and the spring function.
- the current flow function involves a choice of materials having satisfactory conductive properties to limit heating: typically copper, aluminum or their alloys. But the use of such materials to ensure the spring function causes significant limits on the contact dimensions, especially because of the constraints and the resulting effort, in particular because of a maximum stress not to be exceeded in the material . It follows that for a given size, this second example has a limit value of nominal current.
- the invention aims to modify such a monobloc contact, or design close to such a monobloc contact, to increase the nominal current in a given space.
- the invention relates to a contact contact type electric contact device with a high nominal current between a first part which is conductive and a conductive surface of a second part, this device comprising a flexible rod connected to a first mechanical joining element and to the first piece, a contact portion applied to the conductive surface of the second piece and at least one metal contact blade disposed at a first end between a first end of the shank and the first piece characterized in that the flexible shank is conductive and in that the at least one metal blade is at its second end connected to the second end of the flexible rod with a second mechanical and electrical connection element.
- the first joining element may comprise a screw or a rivet.
- the second joining element may comprise a rivet.
- the second joining element can be made by crimping and deformation of a prominent part of a contact pad.
- the first joining element can be connected to the first part by screwing.
- the flexible rod and the contact portion form a single piece.
- the flexible rod and the contact portion are made of copper, aluminum or one of their alloys.
- the device of the invention makes it possible to increase the nominal current for a given size.
- FIG. 1 illustrates an exemplary contact device of the known art.
- Figures 2 and 3 illustrate two embodiments of the device of the invention.
- Figures 4 to 6 illustrate features of the device of the invention as illustrated in Figures 2 and 3.
- a conductive flexible elongate contact element 20 which is the main conductor of the electric current, provides a spring function and a contact pad function. It can be made in one piece, as illustrated in FIG. 2, or in two pieces, as illustrated in FIG. 3. At least one metal blade 21 forms a complement of section for the passage of electric current so as to obtain a finger of simple structure in a given space allowing the passage of a maximum of nominal current.
- the contact element 20 comprises a first portion 22 in the form of a rod and a second portion 23 in the form of contact pads which can be part of the same part or two separate parts.
- a first end of the at least one blade 21 is disposed between the first part 10 and the first end of the first part of the conductive part 20, itself connected to this first part 10 via the joining element 16.
- a second end of the at least one blade 21 is connected to the second end of the first portion 22 of the contact element 20 by a mechanical and electrical connecting element 24.
- the at least one contact blade makes it possible to increase the nominal current without increasing the contact force.
- the reference 25 represents the contact zone between the second part 23 of the contact element 20 and the conductive surface 26 of the second part 11.
- Figures 4 to 6 illustrate exemplary embodiments of the first and second junction elements 16 and 24.
- first joining element 16 illustrated in FIG. 4:
- This first joining element 16 can be made using a screw or a rivet 30 connecting the contact element 20 and the contact blade or blades 21 to the first part 10. A single connection then ensures the junction of the three elements: first part 10, metal blades 21 and contact element 20.
- a force distribution washer 31 disposed under the head screw or rivet.
- the second junction of the blade or blades 21 and the contact element 20 can be made either by rivet 40, as shown in Figure 5, or by crimping and deformation of a prominent portion of a contact pad 50 inserted into the blade (s) 21 and the contact element 20, as shown in Figure 6.
- Another effective solution uses a screw for both variants considered above. In all cases the same rules as the second point concerning the first connecting element with the first part apply.
- the contact element 20 may have a length of between 3 and 15 cm, a thickness in its first portion 22 of between 3 and 20 mm.
- Each metal blade may have a thickness of between 0.1 mm and 1 mm.
- the contact element 20 and the blades may be made of copper, aluminum or one of their alloys.
