ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates to an electrical connector, and more particularly to a mobile phone cable connector with means for strengthening guiding posts thereof.
An electrical connector is often desired to engage with a mating electrical connector, in which guiding means is required to facilitate the mating and to ensure positioning. A conventional electrical connector is illustrated in U.S. Des. Pat. No. 351,136, as shown in FIG.
5
. The electrical connector comprises an insulative housing
20
and a plurality of contacts
30
received in a middle portion of the housing
20
. A pair of guiding posts
21
respectively forwardly extends from opposite sides and beyond a front face
22
of the housing
20
for guiding an insertion of a mating electrical connector (not shown) into the electrical connector.
The guiding posts
21
are relatively slender and have no shielding, and therefore are of weak strength. The weak nature of the guiding posts causes them to be readily broken if the connector is carelessly connected with the mating connector.
BRIEF SUMMARY OF THE INVENTION
A main object of the present invention is to provide an electrical connector which has guiding means with improved strength.
Another object of the present invention is to provide shells used in a mobile phone connector which can strengthen and shield guiding posts of the connector.
An electrical connector in accordance with the present invention comprises an insulative housing, a plurality of contacts received in the housing, an upper shell, a lower shell, a base, a cover and a pair of latches. The housing comprises a projecting portion forwardly extending from a front thereof for receiving contact portions of the contacts. The base includes a pair of lateral walls defining a cavity therebetween for receiving the housing. A pair of guiding posts is respectively formed projecting forwardly from a front end of the lateral walls. Each guiding post and associated lateral wall longitudinally defines a slit in a middle thereof for receiving a corresponding latch therein. The upper shell comprises an upper wall, two side walls, a rear upper flap and an upper enclosing portion. The lower shell comprises a bottom wall, a lower flap upwardly extending from a rear edge of the bottom wall and a lower enclosing portion. A pair of side retaining arms extends upward from opposite edges of the lower enclosing portion. A front retaining arm inwardly extends from a forward edge of each side retaining arm. The side retaining arms and the front retaining arms shroud the guiding posts for strengthening and shielding the guiding posts.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
