Abstract: 1. A device for assembly and electrical connection of modular switchgear units, such as circuit breakers, each module housing at least one breaking unit of a phase or of the neutral, fixed on a support rail and having cases adjoined side by side, said device comprising a connecting means, such as a comb, for connecting all the switchgear units, extending parallel to the longitudinal direction of the rail and having a series of teeth successively distributing several phases 1, 2, etc., in repetitive manner along the rail, with a tooth distributing the neutral interposed between two successive phase teeth or arranged facing each of the phase teeth, said teeth being designed to be inserted in corresponding terminals of said switchgear units, characterized in that each switchgear unit A comprises on its connection face for connection to the comb, a combination formed by connection terminals b and locations 1, said terminals b being designed to receive the used teeth D and the locations (e, I) the unused teeth of the comb P. 2. The device according to claim 1, characterized in that the each switchgear unit A comprising at least one module (m, n, o, p), each of the modules comprises on its connection face a combination with two elements formed by terminals b and/or locations (e, I), the distance separating two successive teeth D corresponding to one half-module. 3. The device according to claim 1 or 2, characterized in that the distance between two successive teeth, corresponding to the pitch of the switchgear units, is appreciably 9 mm. 4. The device according to any one of the claims 1 to 3, characterized in that the above-mentioned comb P distributes three phases and the neutral. 5. The device according to any one of the claims 1 to 4, characterized in that the teeth (Dn) distributing the neutral have a different position in the depthwise direction<:> of the switchgear units A with respect to the teeth (Dph) distributing a phase, so as to avoid a staggered assembly of the comb P. 6. The device according to any one of the foregoing claims, characterized in that the above-mentioned modular switchgear units comprise differential or not circuit breakers or switches (9, 10, 11, 12, 13, 16), associated or not to auxiliary units (57) and/or control units (59). 7. The device according to any one of the foregoing claims, characterized in that each module (n, o, p) of the switchgear units houses a single breaking unit of a phase or of the neutral. 8. The device according to any one of the claims 1 to 6, characterized in that at least one module (m) of the switchgear units houses two breaking units respectively of the neutral and of a phase. 9. The device according to any one of the claims 1 to 8, characterized in that the terminals comprise connecting elements internal to the switchgear units, and the locations are formed by housings (I) arranged in the case of said switchgear units. 10. The device according to any one of the claims 1 to 8, characterized in that the terminals comprise connecting elements (75) protruding out from the switchgear units, and that the locations comprise spaces (e) left free between the terminals at the level of the unused teeth. 11. A switchgear unit comprising on its connection face a combination of connection terminals b and locations (e, I) so as to be able to be supplied and electrically connected to other switchgear units A of the same type by a device according to any one of the claims 1 to 10. 12. The switchgear unit according to claim 11, characterized in that it is a three-pole circuit breaker (41) and that it comprises three modules (m, n, o), said modules each comprising, successively, from one side of the switchgear unit A to the other, a location (44) and a terminal (45). 13. The switchgear unit according to claim 11, characterized in that it is a three-pole plus neutral circuit breaker (38) and that it comprises three modules (m, n, o), said modules successively comprising from one side of the switchgear unit A to the other, two terminals (46, 47) for the first module (m), and a location (48, 50) and a terminal (49, 51) for the other two modules (n, o). 14. The switchgear unit according to claim 11, characterized in that it is a single-pole plus neutral circuit breaker and that it comprises two modules (m, n) comprising on their connection face, respectively, a terminal (62) and a location (63) for the first module (m), and a location (64) and a terminal (65) for the second module. 15. The switchgear unit according to claim 11, characterized in that it is a three-pole plus neutral circuit breaker (52) and that it comprises four modules (m, n, o, p), said modules successively comprising from one side of the comb P to the other, a terminal (66) and a location (67) for the first module (m) and a location (68, 70, 72) and a terminal (69, 71, 73) for the other three modules (n, o, p). 16. A switchgear unit comprising at least one module (m, n, o, p), each of the modules comprising on its connection face a combination of two elements formed by terminals b and/or locations (e, l), the distance separating two successive teeth D corresponding to one half-module.
