Problems solved by technology

The problem with such non-releasable electrical connectors is that the cable can snag obstacles, possibly causing the rider to lose control of the bike and severely damage the cable
However, when the electrical connector is exposed to various temperature changes, this causes the components of the electrical connector to expand or contract according to the temperature change
This is a particular problem when electrical connectors are snap-fit
In particular, the engaging force and snapping feeling between mated connectors deteriorates when exposed to various temperature changes for a long time

Abstract

Various electrically controlled devices of a bicycle are electrically coupled together by multi-conductor electrical cords. Preferably, the ends of the electrical cords have an electrical connector that mates with a corresponding electrical connector of an electrically controlled device. The electrical connectors are designed to be coupled together by a snap fit. Each electrical connector attached to the end of the electrical cord has an electrical contact housing with electrical contacts and an outer casing molded about the electrical contact housing to form a tubular portion radially spaced from the outer end of the electrical contact housing. A retaining ring is located in an annular groove formed in an exterior surface of the outer casing to provide an additional coupling force. Preferably, an annular sealing member formed of a resilient and compressible material is located in an annular space formed between the tubular portion and the electrical contact housing.

Description

technical field [0001] The invention relates to an electrical connector. In particular, the present invention relates to an electrical connector that mates with other electrical connectors by snap fit. Background technique [0002] Cycling has gradually become a popular recreational activity and a mode of transportation. In addition, cycling has become a very popular competitive sport for both amateurs and professional athletes. Whether the bicycle is used for recreational activities, transportation or competition, the bicycle industry is constantly improving the various components of the bicycle. In particular, manufacturers of bicycle components are constantly improving the performance, reliability and appearance of individual components. [0003] In recent years, bicycles have come with electronically driven transmissions with smoother shifting. These electronic drive transmissions include a rear multi-stage sprocket assembly with a motorized rear derailleur and a fro...
