ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to a multiple-contact micron connector, and more particularly to a micron connector in which the first type terminal resiliently tightly clamps two sides of the second type terminal to form two electric contacts.
2. Description of the Prior Art
FIGS. 1 and 2
show an existent micron connector applied to telecommunication products. The micron connector includes a base seat main body
91
, a socket main body
92
, first type terminals
93
and second type terminals
94
. Two sides of the base seat main body
91
are respectively parallelly formed with multiple terminal receptacles
911
. A fixing seat
912
is disposed on outer side of each terminal receptacle
911
. An insertion cavity
912
a
is formed in the fixing seat
912
. A fixing pin
931
of the first type terminal
93
is correspondingly inserted in the insertion cavity
912
a
of the fixing seat
912
. A tail end contact pin
932
of the first type terminal
93
extends into the terminal receptacle
911
. The socket main body
92
has two sidewalls
921
. The distance H
1
between the two sidewalls
921
is equal to or slightly smaller than the distance H
2
between inner sides of the fixing seats
912
on two sides of the base seat main body
91
. Accordingly, the socket main body
92
can be correspondingly inserted in the base seat main body
91
. The inner sides of the two sidewalls
921
of the socket main body
92
are respectively parallelly formed with multiple terminal cavities
922
for firmly inserting the second type terminal
94
therein. When the socket main body
92
is inserted into the base seat main body
91
, a rear section
941
of the second type terminal
94
correspondingly resiliently contacts with one side of the tail end contact pin
932
of the first type terminal
93
to electrically connect the first type and second type terminals
93
,
94
.
The above micron connector has very small volume. The length of such micron connector is about 5~40 mm (varied with the number of accommodated terminals). The width of such micron connector is about 4 mm. The pitch between adjacent terminals is only below about 0.5 mm. Therefore, the tail end contact pin
932
of the first type terminal
93
can be only resiliently micro-biased to lean against outer side of the rear section
941
of the second type terminal
94
to electrically connect the first type and second type terminals
93
,
94
. The base seat main body
91
and the socket main body
92
are made of plastic material. Due to contraction of the material, in manufacturing, the distance H
2
between the fixing seats
912
of the base seat main body
91
or the distance H
1
between the two sidewalls
921
of the socket main body
92
is often unequal to the originally designed size. Therefore, it often takes place that the distance is too long and the tail end contact pin
932
of the first type terminal
93
can hardly resiliently tightly lean against outer side of the rear section
941
of the second type terminal
94
. This leads to poor contact.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide a multiple-contact micron connector including: a base seat main body, a longitudinal insertion channel being formed on upper end face of the base seat main body, a central partitioning board being disposed at a center of the insertion channel, two sides of the partitioning board being respectively parallelly formed with multiple terminal receptacles; a socket main body, two sides of the socket main body being parallelly formed with multiple terminal receptacles, whereby the socket main body can be correspondingly inserted in the insertion channel of the base seat main body; multiple first type terminals respectively inserted in the terminal receptacles of the base seat main body, each first type terminal having a U-shaped section bridged over a support board on outer side of the terminal receptacle, a rear end of a first leg of the U-shaped section being radially bent to form a connecting pin for connecting with a circuit board, a resilient arm extending from a rear end of a second leg of the U-shaped section, a contact pin upward extending from a rear end of the resilient arm; and multiple second type terminals each having a U-shaped section inserted in and bridged over the terminal receptacle of the socket main body, a top end of a first leg of the U-shaped section being bent to form a horizontal connecting section for connecting with another circuit board, a resilient section being integrally connected with a second leg of the U-shaped section, a contact section upright integrally extending from a rear end of the resilient section, whereby when the socket main body is correspondingly inserted into the insertion channel of the base seat main body, the second leg of the U-shaped section of the first type terminal resiliently abuts against the first leg of the U-shaped section of the second type terminal to form a first electric contact and the contact pin of the rear end of the first type terminal resiliently contacts with the contact section of the rear end of the second type terminal to form a second electric contact.
