Abstract
Abstract A multiway connector comprising a support part and a cover part including plugs. The plugs with the first electrically conducting contact elements and electrical conductors are arranged on the support part. The two-part construction of the multiway connector permits a problem-free mounting of the electrical conductors in the vicinity of a support part front face, for example, in guide grooves of the support part. The construction of the multiway connector is particularly suitable for the joint electrical contacting of electrically operable fuel injection valves.

Claim 1
Independent Claim
183 words
A multiway connector (1) for joint electrical contacting of several electrically energizable units of internal combustion engines, which comprises separate plugs (8) arranged in said multiway connector, each of said separate plugs have at least two plug apertures (9), a separate first electrically conducting contact element (11) is arranged in each of said plug apertures which is connected at one end (11") to separate electrically conducting contact elements of a separate electrically energizable unit by means of a plug contact connection, and a second end (11') of each of said first electrically conducting contact elements is connected with one of at least two separate electrical conductors which electrically connect the first electrically conducting contact elements of the separate plugs to at least one electrical contact of an electrical connection plug (14) moulded onto the multiway connector and which are arranged within the multiway connector, the multiway connector (1) is formed of a support part (2), a cover part (3), the plugs (8) and the electrical conductors (12) whereby said plugs (18) and said electrical conductors (12) are arranged on the support part (2).
Claim 2
Dependent Claim
183 words
A multiway connector (1) for joint electrical contacting of several electrically energizable units of internal combustion engines, which comprises separate plugs (8) arranged in said multiway connector, each of said separate plugs have at least two plug apertures (9), a separate first electrically conducting contact element (11) is arranged in each of said plug apertures which is connected at one end (11") to separate electrically conducting contact elements of a separate electrically energizable unit by means of a plug contact connection, and a second end (11') of each of said first electrically conducting contact elements is connected with one of at least two separate electrical conductors which electrically connect the first electrically conducting contact elements of the separate plugs to at least one electrical contact of an electrical connection plug (14) moulded onto the multiway connector and which are arranged within the multiway connector, the multiway connector (1) is formed of a support part (2), a cover part (3), the plugs (8) and the electrical conductors (12) whereby said plugs (18) and said electrical conductors (12) are arranged on the support part (2).
Claim 3
Dependent Claim
55 words
A multiway connector in accordance with claim 1, in which the support part (2); the plugs (8), having the first electrically conducting contact elements arranged on that support part; the electrical conductors (12) arranged on the support part (2), form a pre-assembled rigid assembly which is at least partially covered by the cover part (3).
Claim 4
Dependent Claim
34 words
A multiway connector in accordance with claim 2, in which the cover part (3) covers a front face (29) of the support part (2), in the vicinity of which the electrical conductors (12) extend.
Claim 5
Dependent Claim
31 words
A multiway connector in accordance with claim 2, in which the cover part (3) is designed in a `U` shape and that the support part (2) is covered on three sides.
Claim 6
Dependent Claim
31 words
A multiway connector in accordance with claim 1, in which the cover part (3) and the support part (2) are connected which each other by means of an elastic snap-type connection.
Claim 7
Dependent Claim
29 words
A multiway connector in accordance with claim 1, in which the support part (2) and the cover part (3) are connected to each other by means of ultrasonic welding.
Claim 8
Dependent Claim
25 words
A multiway connector in accordance with claim 1, in which the cover part (3) is constructed as a plastic shell around the support part (2).
Claim 9
Dependent Claim
22 words

Claim 10
Dependent Claim
26 words
A multiway connector in accordance with claim 1, in which the plugs (8) are connected floatably in horizontal and vertical directions with the support part (2).
Claim 11
Dependent Claim
59 words
A multiway connector in accordance with claim 9, in which the support part (2) has fixing domes (17) along a support part longitudinal axis (15), the number of which corresponds to the number of plugs, with which the plugs (8) are floatably connected in the direction of a dome longitudinal axis (18) and vertically in relation to the same.
Claim 12
Dependent Claim
146 words
A multiway connector in accordance with claim 10, in which each fixing dome (17) has at least one transverse groove (22) which extends in the direction of the dome longitudinal axis (18), which is open towards a dome front face (20) provided on the free dome end (19) and towards the dome circumference (21), this groove permitting an elastic compression of the free dome end (19) in a radial direction when the plug (8) is pushed onto the fixing dome (17), so that a snap-in nose (25) provided on the plug (8) or on the fixing dome (17) can engage with a locating groove (26) provided on the plug (8) or on the fixing dome (17), such that the plug (8) is movable in relation to the fixing dome (17) in the direction of the dome's longitudinal axis (18) and vertically in relation to the same.
Claim 13
Dependent Claim
