ABSTRACT:

FIELD OF THE INVENTION
The present invention is related to a battery connector, and especially to a battery connector mounted on a printed circuit board and having a housing with improved rigidity.
BACKGROUND OF THE INVENTION
An electrical connector has a plurality of contacts for electrically transmitting signals and a housing for receiving the contacts. The art related to the present invention is disclosed in Taiwan Patent Application Nos. 84210634, 83107591, 83209060 and 85213851 and U.S. Pat. No. 5,674,078.
Referring to
FIG. 1
, a conventional electrical connector
100
includes a plurality of contacts
102
(only one shown for simplicity) and a housing
104
for receiving the contacts
102
. The housing
104
includes a plurality of partitions
105
and thin connecting walls
107
to define cavities
106
between a rear surface
108
and a front surface
110
thereof for receiving the contacts
102
. A right sidewall
112
of each cavity
106
forms a notch
114
exposed to the rear surface
108
. Each contact
102
has a base portion
116
and a blade portion
118
extending from the base portion
116
. A tab
120
perpendicularly extends from the base
116
and forms two barbs
122
for being interferentially fit into the notch
114
.
However, since the cavities
106
are laterally defined through the housing
104
, the housing
104
can be easily warped around a direction M and the partitions
105
can be easily deformed thereby complicating assembly of the contacts
102
into the cavities
106
. Furthermore, since each right sidewall
112
of the cavity
106
forms a notch
114
, the rigidity of the partition
105
is reduced and the engagement between the contact
102
and the housing
104
is weakened.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an electrical connector having a housing with improved rigidity thereby ensuring reliable assembly of contacts attached therein.
An electrical connector of the present invention comprises a housing and a plurality of contacts received in the housing. The housing has a base portion forming a mounting surface, a closed rear face and a front face. A plurality of cavities is defined in the mounting surface and is exposed to the front surface. A partition, extending along a front-rear direction of the housing, is formed in each cavity to divide the cavity into a first chamber and a second chamber. Each contact includes a blade portion, a fixing post and a contact tail substantially parallelly extending from an edge of the blade portion. The fixing post forms at least one barb extending toward the contact tail to interferentially engage with the partition to secure the contact in the housing. The contact tail is received in the first chamber and forms a terminating portion perpendicularly extending from a free end thereof for electrically connecting with a printed circuit board.
Other objects of the present invention can be drawn from the following description.
