Embodiment Construction

[0019] FIG. 1 shows a fuel pump with a pump stage 2 of a fuel car driven by an electric motor 1, and the fuel pump also has a connecting piece 4 fixed to the body 3. The connecting piece 4 has a connecting pipe 5 for a fuel supply pipe leading to the internal combustion engine of the automobile. Furthermore, the connecting piece 4 has electrical contacts 6 for the electric motor 1 of the fuel pump.

[0020] Fig. 2 shows the connecting member 4 enlarged in a partial sectional view. The electric contact 6 is installed on the plug 7. The plug 7 has a plastic housing 8 with a choke 9 protruding from it, and the plug 7 also has two brushes 10 for a collector of the electric motor 1 in FIG. 1. The brush 10 moves in the long guide rail of the connecting piece 4 and exerts a pretensioning force in the direction of the motor 1 shown in FIG. 1 by means of elastic parts. The plug 7 is fixed in a socket 12 of the connector by the positioning mechanism 11 and passes through the groove 14 of th...

Abstract

In the case of a fuel pump, a plug for fixing electric contacts is manufactured from a material which is capable of swelling with fuel, and is inserted into a receptacle of a connecting piece by being fitted therein. Furthermore, the plug and the connecting piece have latching means for simplifying the pre-assembly. The connecting piece requires a particularly low number of components and can be manufactured cost-effectively.

Description

Technical field [0001] The invention relates to a connecting piece for a fuel pump. The connecting piece is provided with a socket for a plug with an electric contact, which is connected to the electric motor of the fuel pump and the power grid. Background technique [0002] For today's automobile fuel pumps, such connectors are used in the common body of a closed motor and a pump stage, which is already well known in practical applications. The electrical contacts are assembled and fastened through the sealing lip assembled on the connector. In this way, the fuel supply pressure generated by the fuel pump is absorbed by the connecting piece and transmitted to the connecting pipe of the fuel supply pipe. The disadvantage of the known connectors is that they are laborious to install. In addition, the plastic connector may be damaged during the installation of the electrical contact. [0003] In practical applications, a connector is also known in which the plug is encapsulated by ...
