[0001] DESCRIPTION [0002] RELEASE LOCKING BOARD TO BOARD CONNECTOR [0003]

The present invention relates to a structure of a board-to-board connector, and more particularly, to a board-to-board connector structure that allows a user to feel a click to recognize completion of a fastening when a board- Type board connector so as not to be separated arbitrarily.

In general, the board to board (BtoB) connector is used to connect boards with various circuit printed boards. As shown in FIG. 1, the B-to-B connector includes a male connector 10 and a female connector 20, and the male connector 10 is fitted to the female connector 20 so that the female connector 20 can be coupled to each other.

After the male connector 10 and the female connector 20 are once inserted and fastened, they must be maintained in a coupled state. However, the male connector 10 and the female connector 20 may be separated from each other by an external force. In order to prevent this, as shown in the figure, the terminals 12 and 14 are provided with protruding portions facing each other, so that these portions are mutually overtightly engaged with each other to generate a bonding force.

However, since the terminals 12 and 14 have the elastic characteristics of metal, when the external force is applied to the terminals 12 and 14 even when they are coupled to each other, they can be easily separated from each other while being elastically deformed again . In this case, the male and female connectors can be easily separated at the time of a slight impact or drop. Also, there is a disadvantage in that it is difficult to recognize whether the mutual coupling is completely completed by vibration or noise, that is, a so-called clicking feeling.

In order to prevent this, it is possible to deform the size and shape of the engaged protrusions more sharply so as to induce more rigid coupling, impact, and noise generating operation. In this case, however, the coupling itself becomes very difficult, There is a problem that breakage is caused, so that when the male and female connectors are to be removed for repairing the parts, the connector may be broken or the soldered portion on the board such as the PCB may be separated.

At this time, a coupling part 220 is formed in both sides of the room, and a pair of coupling members 300 are inserted into the coupling part 220 and are seated.

The fastening part 220 is formed with an opening part 222 which is opened upward in the central part and a support part 226 is formed on both sides of the opening part 222. [ Below the support portion 226, a horizontally horizontally open seating portion 224 is formed. A spacing portion 223, which is an open space spaced apart from the portion to which the second terminal 202 is coupled, is formed inside the support portion 226.

The fastening member 300 has a rectangular basic shape in which a locking hole 320 is formed inside as in the shape of a shaft and includes a shaft portion 330 and a pair of side portions facing upward from both ends of the shaft portion 330 310, and a side portion 310 of the fixing portion 340. [

The pressing part 350 is protruded from the shaft part 330 at an angle of about 90 degrees with respect to the side part 310 so as to face the center of the second base 210. The pushing portion 350 is positioned so as to be exposed upward in the opening portion 222.

The fitting portion 360 protruding toward the outside of the second base 210 is formed in the fixing portion 340. The fitting portion 360 can be fitted in the fitting seat portion 228 located at the upper end of the outer outer frame of the opening portion 222. [

It is preferable that the fastening member 300 is formed in a rectangular frame shape in which a latching hole 320 is formed on the inner side as shown in the figure. In some cases, the fastening member 300 is formed by bending or deforming the shape of the plate, The same function may be performed.

The fastening member 300 is moved downward from the upper part of the spacing part 223 so that the shaft part 330 is positioned at the lower side and the shaft part 330 pulled through the spacing part 223 is pushed outward from the lower end, . At this time, the upper portion of the shaft portion 330 is supported by the support portion 226, so that it can be pivoted while keeping its position.

The pushing portion 350 positioned on the center side of the shaft portion 330 is exposed to be viewed from above through the opening portion 222. When the fastening member 300 is seated in the seating portion 224, The pushing portion 350 is positioned at an obliquely upward position toward the inside of the second base 210.

4 and 5 are views showing the state before and after the engagement of the first and second connectors according to the present invention. Referring to FIG. 4, in a state before assembling, the fastening member 300 has an open shape. Referring to FIG. 5, in a state after the fastening member 300 is assembled, ) To hold the shape.

8, when the operator rotates the fastening member 300 outward and provides the side portion 310 with an external force capable of overtaking the support protrusion 227, the shaft portion 330 in the seat portion 224 is positioned at the center The fastening member 300 is pivoted by pushing the pressing portion 111 and the fixing portion 340 is pulled out from the outside of the fastening portion 116 by the principle of the lever. As a result, the first connector 100 can be freely discharged upward. A pivotal fixing portion 225 protruding downward from the upper support portion 226 is formed at a boundary portion between the seating portion 224 and the spacing portion 223 so that the shaft portion 330 seated in the seating portion 224 can be easily It helps to prevent it from falling out and helps it to rotate in place.

Figs. 9 and 10 are diagrams showing a preparation state in which the fastening members according to the present invention are arranged in the second connector before fastening. Fig. Referring to FIGS. 9 and 10, the fastening member 300 should be maintained in a state in which the pushing portion 350 is lifted up through the opening 222 in the state before the fastening. To this end, a latching protrusion 227 for supporting the side portion 310 of the side is provided and supported in a state as shown in FIG.

In addition, a fitting portion 360 extending downward outward is formed in the fixing portion 340 of the fastening member 300, and an upper end of the outer portion of the fastening portion 220, that is, Shaped fitting portion 228 is provided. The fitting portion 360 is inserted into the fitting seating portion 228 with interference so that the initial position of the coupling member 300 can be maintained by the frictional force.

The present invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
