FIELD OF THE INVENTION
The present invention relates to a connector that includes two removable plates with a spring biased therebetween and the two release plates release the terminal board by pushing them toward each other.
BACKGROUND OF THE INVENTION
A conventional connector used in electrical or electronic equipment generally includes a flexible case which is squeezed to force the contact terminals to be connected with the terminal board. It requires a lot of force to engage the connector with or disengaged from the terminal board. Often, the contact terminals of the connector are bent or even broken. It is inconvenient for the assemblers to proceed connection between the connectors and the terminal boards.
The present invention intends to provide a quick release connector which has two release plates each have a hook for engaging with the terminal board and a spring is biased toward the two release plates so that when pushing the two release plates toward with each other, the two hooks are moved away from the terminal board and the connector is disengaged from the terminal board.
SUMMARY OF THE INVENTION
The present invention relates to a connector that includes a base having a plurality of contact terminals extending through a rear frame thereof and two side frames are connected to the rear frame so that one of two ends of the contact terminals are located between the two side frames. Each side frame has a slot defined therein so as to receive one of two release plates respectively. Each release plate has a hook so as to hook one of two recesses of a terminal board respectively. A spring is connected between the two release plates so that the two hooks can pull each other. The two hooks are removed from the terminal board simply by pushing the two release plates.
The present invention is described at the following drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 2 is an exploded view showing the connector of the present invention;
FIG. 3 shows that the terminal board is to be inserted in the connector;
FIG. 4 shows that the terminal board is hooked by the two hooks of the two release plates; and
FIG. 5 shows that the two hooks are disengaged from the terminal board by pushing the release plates.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 and 2, a connector 1 in accordance with the present invention comprises a case 11 having a top plate, a bottom plate and a front plate connected between the top plate and the bottom plate. An elongated hole 111 is defined through the front plate. A base 12 is engaged with a space 11 between the top plate and the bottom plate of the case 11 and has a plurality of contact terminals 15 extending through holes 123 defined through a rear frame of the base 12. A first end of each contact terminal 15 extends from an outside of the rear frame that the contact terminals 15 extend so as to be connected to a part, which is not shown. Two side frames are connected to the rear frame and the second ends of the contact terminals 15 are located in a space 17 between the two side frames of the base 12. Each contact terminal 15 has a bent portion which conveniently contacts with contacted points on a terminal board 2. The second ends of the contact terminals 15 can be accessible from the elongated hole 111.
Each side frame has a slot 122 defined therein and two release plates 13, 14 extend through the two slots 122 of the two side frames respectively and each have a hook 132/142 which may hook one of two recesses 21 of the terminal board 2 respectively as shown in FIG. 4. A guide groove 121 is defined in each of the two side frames of the base 12 so as to guide two sides of the terminal board 2 to be inserted in the case 11. The two release plates 13, 14 are overlapped with each other and each release plate 13/14 has a protrusion 133/143 extending from a mediate portion thereof. The two protrusions 133, 143 extend toward with each other and a spring 16 is biased toward the two protrusions 133, 143 so as to pull the two hooks 132, 142 toward each other. Each of the two release plates 13, 14 has a pushing end 131/141 which is exposed on an outside of the base 12 and can be conveniently pushed.
As shown in FIG. 3 to 5, each of the two hooks 132, 142 includes an inclined leading edge so that when the terminal board 2 is inserted through the elongated hole 111, the two hooks 132, 142 are pushed aside by the terminal board 2 pushing the inclined leading edges, till the hooks 132, 142 are engaged with the two recesses 21 of the terminal board 2. As shown in FIG. 5, when the user pushes the two pushing ends 131, 141 of the two release plates 13, 14, the spring 16 is compressed and the two hooks 132, 142 are moved away from the recesses 21 of the terminal board 2. By this way, the connector 1 is easily disengaged from the terminal board 2.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
