Abstract: For arranging an air mass meter at a flow channel, the flow channel has a housing section with a flange surrounding a receiving opening for the air mass meter. The air mass meter has a socket with a contact surface that is facing the flange. Fasteners are provided that attach the socket on the housing section. The socket and the housing section have elements for positioning the air mass meter free of play relative to a flow direction of a fluid flow that is guided in the flow channel.

Abstract: A pair of mated connector (11, 12) are latched together by a pair of studs (21) on a first connector that are inserted into a pair of sleeve assemblies (22) on the second connector, with each stud having a stud groove (40) that receives an inwardly projecting flange (32) of the sleeve assembly. The sleeve assembly includes an outer sleeve (54) with an internal sleeve groove (28), and a spring clip (23) lying in the sleeve groove. The spring clip is largely in the form of a cylinder with an axially-extending slot (31) that allows the cylinder to resiliently expand and contract. The spring clip is trapped in the sleeve groove and has an inwardly-projecting flange (32) that snaps into the stud groove when the stud is fully inserted.

Abstract: A connector assembly includes a first connector (2) with a forwardly-projecting pin (18) having a groove (32), and a second connector with a sleeve (20) having a passage (21) for receiving the pin. The second connector also has a spring clip (24) that deflects into the pin groove when the connectors are mated, to resist pullout of the pin and therefore unmating of the connectors. The groove in the pin has a radially-outward forward wall portion (36) which is angled to face at least 20.degree. from the pin axis, so that when the connectors are pulled apart, a portion of the clip lying in the pin groove can ride radially outwardly along the inclined wall to allow the connectors to be unmated. The clip is largely U-shaped with a base (72) and with bent arm free end portions (73) each lying in opposite recess portions (27, 26) of a circumferential slot (23) in the sleeve.

Abstract: A locking device is provided for an electrical connector system to hold two connectors, (1, 2) together. The locking device includes S-shaped sheet metal locking hooks (9) on a second connector that lock into cutouts (8) on a plate (7) of the first connector. One curved arch (14) of the S-shaped sheet metal hook snaps into the cutout and resists unmating.
