Description

Sunken plate type easy lock and unlock connector

The present invention relates to the technical field of connectors, in particular to a sunken plate type easy-to-lock and easy-to-unlock connector that can be locked and unlocked on a printed circuit board and a flexible circuit board.

Traditionally, the sunken plate type easy lock and release connector is locked on the printed circuit board, so that the cables connected to the sunken plate type easy lock and release connector, such as single-core copper wires or copper stranded wires, can be electrically connected to the electrodes on the printed circuit board through the sunken plate type easy lock and release connector.

In view of this, the present invention proposes a sunken plate type easy-lock and easy-unlock connector that can be used to solve problems that cannot be solved by traditional methods.

The first purpose of the present invention is to provide a sunken type easy-lock and easy-unlock connector that can connect a printed circuit board and a flexible circuit board and is embedded in the printed circuit board, for example, for use in a backlight module, etc.

The second purpose of the present invention is to provide a single or multiple fasteners based on the above-mentioned sunken type easy lock and unlock connector to fix the sunken type easy lock and unlock connector on the printed circuit board.

The third purpose of the present invention is to provide a latch to lock and unlock the flexible circuit board based on the above-mentioned sunken plate type easy-lock and easy-unlock connector.

The fourth purpose of the present invention is to provide a pressing part of the buckle on the visible surface of the above-mentioned sunken plate type easy-lock and easy-unlock connector, so that the operator can easily assemble and unlock it.

The fifth purpose of the present invention is to expose a relatively low-height rubber core and buckle portion on the sinking plate surface (i.e., the second surface mentioned in the present invention) based on the above-mentioned sinking plate type easy-lock and easy-unlock connector.

The sixth purpose of the present invention is to make the surface of the pressing piece no higher than the surface of the main body according to the above-mentioned sunken plate type easy-lock and easy-unlock connector, so as to avoid the problem of unlocking due to accidental touch.

In order to achieve the above-mentioned and other purposes, the present invention provides a sunken plate type easy-lock and easy-release connector for connecting a printed circuit board and a flexible circuit board. Among them, the printed circuit board forms an opening and the two sides of one end of the flexible circuit board respectively form a snap hole. The printed circuit board has a first surface and a second surface. The sunken plate type easy-lock and easy-release connector includes a rubber core, a plurality of snap parts, a plurality of first terminals and a plurality of second terminals. The rubber core includes a main body, a plurality of action parts, a plurality of snap parts, a plurality of first terminal grooves, a plurality of stop parts and a plurality of second terminal grooves. The main body can be arranged in the opening of the printed circuit board so that a part of the rubber core is exposed on the first surface and a part of the rubber core is exposed on the second surface. The main body forms an insertion port and a accommodating space to be able to insert the flexible circuit board. The action parts are formed on two sides of the body. The buckle parts are formed on two sides of the accommodating space. The first terminal grooves are formed on a front edge of the accommodating space and the second terminal grooves are formed on a rear edge of the accommodating space. The stopper parts are arranged to protrude from the body to stop the rubber core at the opening. The buckle parts respectively include a buckle block, a connecting part, a pressing part, an elastic part and a base. The connecting part connects the pressing part and the buckle block, and the elastic part connects the connecting part and the base. The buckle block can be arranged corresponding to the buckle hole and the pressing part can receive an action force to generate deformation in the elastic part. Among them, the base includes an insert and a fixing part. The insert can be arranged on the printed circuit board by inserting the snap parts into the body and the fixing part. The first terminals are arranged in the first terminal slots. The second terminals are arranged in the second terminal slots. The second terminals are the same as or different from the first terminals. When the flexible circuit board is inserted into the insertion port, the snap blocks lock the snap holes, and the pressing part generates a force through a press or a slide to deform the elastic part to unlock the locking state of the snap block and the snap holes.

Compared with the traditional sunken plate type easy-lock and easy-unlock connector, the present invention proposes a sunken plate type easy-lock and easy-unlock connector, which can be applied to printed circuit boards and flexible circuit boards, for example, to backlight modules that provide multiple light-emitting units.

The body 1022 can be set in the opening of the printed circuit board 2 so that a part of the rubber core 102 is exposed on the first surface and a part of the rubber core 102 is exposed on the second surface. In addition, the body 102 forms an insertion port 1021 and a receiving space SP to be able to insert the flexible circuit board 4. Here, the insertion port 1021 can also form a chamfer 10218 so that the flexible circuit board 4 can smoothly enter the insertion port 1021.

The action parts 1024 are formed on two sides of the body 1022, and the side surface here refers to the surface indicated in Figure 2(b).

The buckle portions 1028 are formed on two sides of the accommodation space SP, where the side faces refer to the faces indicated in FIG. 2(c).

The first terminal grooves 10210 are formed at a front edge of the accommodation space SP (the side surface here refers to the surface indicated by FIG. 2(d)), and the second terminal grooves 10212 are formed at a rear edge of the accommodation space SP (the side surface here refers to the surface indicated by FIG. 2(c)). Here, the first terminal grooves 10210 and the second terminal grooves 10212 can be arranged alternately to reduce the volume of the sunken plate type easy-lock and easy-unlock connector 10.

Referring to Figures 3(a) to 3(b), they are three-dimensional schematic diagrams of the buckle of Figures 1(a) and 1(b) of the present invention at different angles. Figure 3(a) is a three-dimensional schematic diagram of the buckle of Figures 1(a) and 1(b) of the present invention, and Figure 3(b) is a three-dimensional schematic diagram of the buckle of Figures 1(a) and 1(b) of the present invention.

The buckle 104 includes a buckle block 1042, a connecting member 1044, a pressing member 1046, an elastic member 1048 and a base 10412. The connecting member 1044 connects the pressing member 1046 and the buckle block 1042, and the elastic member 1048 connects the connecting member 1044 and the base 10412. The buckle block 1042 can be set corresponding to the buckle hole and the pressing member 1046 can receive a force to generate deformation in the elastic member 1048.

Here, the base 10412 includes an insert 104122 and a fixing member 104124. The insert 104122 is inserted into the body 1022 and the fixing member 104124 through the buckle portion 1028 and can be set on the printed circuit board 2 (for example, the fixing member 104124 can be welded to the third welding point 30). In addition, the number of inserts 104122 can be one or more structural designs, for example, there is another insert 104122 in Figure 3 (a). The notch 10282 formed by the buckle portion 1028, such as Figure 2 (e), allows the insert 104122 to be inserted into the notch 10282, so that the buckle 104 is fixed to the buckle portion 1028.

Here, the buckle 104 further includes a stopper 10410 and the action portion 1024 further includes an action groove 10242 and an operating portion 10244. For example, the stopper 10410 is in a T-shaped shape to correspond to the action groove 10242 having a concave T-shaped shape, and the operating portion 10244 can be an inclined surface. The stopper 10410 is connected to the pressing member 1046. The stopper 10410 is disposed in the action groove 10242. When the pressing member 1046 is actuated to slide along the operating portion 10244, the pressing member 1046 is linked to the stopper 10410, so that the stopper 10410 moves in the action groove 10242, and the pressing member 1046 is exposed on the second surface.

In one embodiment, the base 10412 further includes a stopper 104126, 104126'. The number of stoppers can be single or multiple, and two are used as an example for illustration. After the buckle 104 is combined with the buckle portion 1028, the stopper 104126, 104126' can be fixed to the buckle 104 on the rubber core 102 by covering the rubber core 102 with the stopper 104.

Refer to FIG. 5, which is a three-dimensional schematic diagram of the first terminal and the second terminal of FIG. 1 (a) and FIG. 1 (b) of the present invention.

The first terminal 1062 is disposed in the first terminal groove 10210. Here, the first terminal 1062 further includes a first soldering portion 10622, a first connecting portion 10624, a first bending portion 10626 and a first contact portion 10628. The first connecting portion 10624 connects the first bending portion 10626 and the first soldering portion 10622. The first contact portion 10628 extends from the first bending portion 10626 to be electrically connected to the flexible circuit board 4, and a first avoidance structure 106210 is provided between the first soldering portion 10622 and the first connecting portion 10624. In another embodiment, the first contact portion 10628 may further include at least one contact point protruding from the surface of the first contact portion 10628, which ensures that the first contact portion 10628 can be smoothly electrically connected to the flexible circuit board 4, especially when the flexible circuit board 4 has an uneven condition or other conditions that make it impossible to smoothly electrically connect.

The second terminal 1064 is disposed in the second terminal groove 10212. Here, the second terminal 1064 and the first terminal 1062 have the same structural design. In other embodiments, the second terminal 1064 and the first terminal 1062 may also have different structural designs. Here, the second terminal 1064 further includes a second welding portion 10642, a second connecting portion 10644, a second bending portion 10646 and a second contact portion 10648. The second connecting portion 10644 connects the second bending portion 10646 and the second welding portion 10642. The second contact portion 10648 extends from the second bending portion 10646 to be able to electrically connect to the flexible circuit board 4, and a second avoidance structure 106410 is provided between the second welding portion 10642 and the second connecting portion 10644. In another embodiment, the second contact portion 10648 may further include at least one contact point protruding from the surface of the second contact portion 10648, which ensures that the second contact portion 10648 can be smoothly electrically connected to the flexible circuit board 4, especially when the flexible circuit board 4 has an uneven condition or other conditions that make it impossible to smoothly electrically connect.

In the above, the first avoidance structure 106210 and the second avoidance structure 106410 are used to keep the first terminal 1062 and the second terminal 1064 away from the opening of the printed circuit board 2 to avoid short circuit caused by electrical conduction with the metal layer (not shown) formed by the opening. Taking FIG. 5 as an example, the first connecting portion 10624 and the first avoiding structure 106210 are bent so that the first avoiding structure 106210 is lower than the first connecting portion 10624 on the same horizontal plane. The first avoiding structure 106210 and the first welding portion 10622 are also bent so that the first avoiding structure 106210 is lower than the first connecting portion 10624 on the same horizontal plane. In other words, the first avoiding structure 106210 is lower than both the first connecting portion 10624 and the first welding portion 10622. In the three-dimensional bottom view of FIG. 1( b ), the first avoiding structure 106210 is higher than both the first connecting portion 10624 and the first welding portion 10622 on the same horizontal plane, so that the first terminal 1062 can avoid direct electrical contact with the metal layer located on the inner side wall of the opening. Similarly, the description of the first terminal 1062 can also be applied to the second terminal 1064, so that the second avoidance structure 106410 is lower than the second connecting portion 10644 and the second welding portion 10642.

Therefore, when the flexible circuit board 4 is inserted toward the insertion port 1021, it can refer to FIG4(a), which is a side view of the sunken plate type easy lock and unlock connector showing that the buckle block 1042 of FIG3(a) locks the buckle hole of the flexible circuit board 4 of FIG1(a). It can also refer to FIG4(b), which is a side view of the sunken plate type easy lock and unlock connector showing that the pressing member 1046 of the buckle member 104 of FIG3(a) generates a force through a sliding motion to cause the elastic member 1048 of FIG3(a) to deform and unlock the buckle block 1042 to lock the buckle hole of the flexible circuit board 4 of FIG1(a). In addition, FIG. 4(b) shows that the pressing member 1046 is subjected to a vector force between the positive X-axis and the positive Y-axis, so that the pressing member 1046 slides in an arc. When the operating portion 10244 below the pressing member 1046 is an inclined surface, the pressing member 1046 will slide along the operating direction OD of the inclined surface to achieve the purpose of sliding unlocking. It is worth noting that the height of the surface of the pressing member 1046 is not higher than the height of the surface of the body 1022. Among them, the surface of the body 1022 is exposed on the second surface to prevent accidental contact with the pressing member 1046 and unlocking.
