ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a fixing structure for connecting a connector and a printed circuit board (P.C.B.).
2. Description of the Related Art
A conventional connector in accordance with the prior art shown in
FIG. 11
comprises an insulator
40
, and multiple board locks
41
. The insulator
40
has multiple receptacles (not shown) for receiving multiple conductors (not shown). The housing
41
has two sides defining two opposite sockets each defining a through hole. Each board lock
41
has a pivot portion
42
inserted into the through hole of the socket of the insulator
40
, and an insertion portion
43
inserted into a printed circuit board
44
, such that the connector may be secured on the printed circuit board
44
. The outer sides of each of the pivot portion
42
and the insertion portion
43
are formed with outward protruded shoulders
45
for providing a locking positioning effect when the board lock
41
is inserted into the insulator
40
or the printed circuit board
44
. The shoulders
45
are rested on the two opposite inner walls of the socket of the insulator
40
when the pivot portion
42
of the board lock
41
is inserted into the insulator
40
. However, the urging force of the shoulders
45
is not efficient enough, so that the board lock
41
is easily released and detached from the insulator
40
. Alternatively, if the urging force is too large, the structure of the insulator will be broken.
SUMMARY OF THE INVENTION
The primary objective of the present invention is to provide a fixing structure for connecting a connector and a printed circuit board, wherein the housing and the board of the connector may be integrally combined rigidly and stably without detachment.
Another objective of the present invention is to provide a fixing structure for connecting a connector and a printed circuit board which may simplify the parts and reduce the cost.
A further objective of the present invention is to provide a fixing structure for connecting a connector and a printed circuit board that may enhance the quality of the product.
In accordance with the present invention, there is provided a fixing structure, comprising:
an insulator, having multiple receptacles for mounting multiple conductors, the insulator having one side having an end face protruded with a chamfered latch boss, and having two sides formed with opposite longitudinal recessed sockets each having a bottom side and an adjoining side formed with a substantially inverted T-shaped through hole; and
multiple board locks, integrally formed to include an upper portion defining a substantially inverted U-shaped pivot portion, and a lower portion defining a slender forked insertion portion, each of the pivot portion and the insertion portion having outer sides formed with outward protruded shoulders, the pivot portion having a middle formed with a flexible locking tab that is slightly protruded outward.
Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.
