ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to a female contact for an electrical connector and more specifically relates to a female contact which has a lance that engages with a housing in which this female contact is mounted.
BACKGROUND
Conventionally, female contacts mounted inside the cavities of connector housings are known to have lances that engage with the inside walls of the cavities. The contacts described in Japanese Utility Model Registration No. 2542184 and Japanese Patent Application Kokai No. H 11-16629, are universally known as examples of such female contacts. The connector disclosed in Japanese Utility Model Registration No. 2542184 is shown as one example in FIG.

. This connector
200
has a housing
202
that has a cavity
204
, and a socket contact
210
which is disposed inside the cavity
204
. The socket contact
210
has on its front part a contact section
206
that accommodates a mating pin contact (not shown in the figures) and has an electrical wire connection section
212
that is connected to a cable
208
. A lance
214
is formed between the contact section
206
and the electrical wire connection section
212
and this lance
214
engages with a recessed groove
216
in the housing
202
, so that the socket contact
210
is anchored inside the housing. The lance
214
is separated in the axial direction from the contact section
206
.
Similarly, in a relay connector disclosed in the latter Japanese Patent Application Kokai No. H 11-16629, the contact section and lance of the contact are disposed so that they are separated in the axial direction of the contact.
In the connector
200
disclosed in Japanese Utility Model Registration No. 2542184, the positions of the contact section
206
and lance
214
are separated in the axial direction thus increasing the dimensions of the socket contact
210
and the size of the housing
202
. The same problem exists with the relay connector disclosed in the latter Japanese Patent Application Kokai No. H 11-16629.
SUMMARY
An object of the present invention is therefore to provide a compact female contact and a compact electrical connector. A female contact is provided having a main body for receiving a pin. The female contact has a resilient contact section positioned at a front end and an embossment also positioned at the front end opposite the resilient contact section such that a mating pin is receivable between the embossment and the resilient contact section. The embossment also has a lance extending outward away from the resilient contact section.
