The terminal 120 is disposed along the front-rear direction of the sheet 110, and the terminal 120 is provided in plural numbers. They are arranged at a predetermined interval in the left and right direction.

The terminal 120 is mounted on the sheet body 110, and is in contact with and electrically connected to the flexible circuit 2 when the first connector 100 and the second connector 200 are combined. Specifically, the terminal 120 is mounted on a sheet After the body 110 is inserted into the inside of the sheet body 110, it is provided so that the end portion protrudes to the case accommodating portion 111. This will be explained in detail later.

The terminal 120 may be disposed to correspond to the terminal portion 2b of the flexible circuit 2 and the pitch (Pitch, P) of the board. For example, the terminals 120 may be disposed to be spaced apart corresponding to 0.5 mm, 1.0 mm, 1.25 mm, and 1.5 mm pitch, and the like.

The second connector 200 includes a housing 210 and a holder 220.

The housing 210 constitutes a main body of the second connector 200, and is formed of a synthetic resin material. The housing 210 can be formed by injection molding, 3D printing, or the like.

The housing 210 is moved to the circuit board 1 in the vertical direction and is received in the housing receiving portion 111 of the first connector 100, and is provided with a resilient arm 230 having a second connector 200 in the accommodating state. Combined locking projection 230'. This will be explained in detail later.

The flexible circuit 2 is inserted and mounted to the housing 210. To this end, a flexible circuit housing portion 211 is formed in the housing 210 for housing the flexible circuit 2. The flexible circuit housing portion 211 can be formed to extend downward from the upper portion and has a concave shape.

The casing 210 is formed with an opening portion 212 for electrically connecting the terminal portion 2b of the flexible circuit 2 and the terminal 120, and exposing the terminal portion 2b of the flexible circuit 2 housed in the flexible circuit housing portion 211. In other words, the opening portion 212 allows the case accommodating portion 111 and the flexible circuit accommodating portion 211 to communicate with each other. According to the above configuration, the terminal 120 is in contact with the terminal portion 2b of the flexible circuit 2 through the opening portion 212, so that the circuit board 1 can be electrically connected to the flexible circuit 2.

In the drawing, the opening portion 212 is formed on one surface of the lower end portion of the casing 210, and the elastic arm 230 is disposed on the upper surface of the other surface of the casing 210 opposite to the one surface.

The housing 210 is inserted and mounted to the sheet body 110. The housing 210 may be disposed to cover at least one surface of the sheet 110 to be supported by the sheet 110. It is shown in the drawing that one end portion of the casing 210 is inserted into the inside of the sheet body 110, and the lower surface of the casing 210 is disposed on one surface of the sheet body 110. The coupling relationship between the housing 210 and the sheet 110 will be described in detail later.

The holder 220 is formed in a plate shape and is inserted into the flexible circuit housing portion 211 to be fixed.

The detailed structure of the retainer 220 fixing the flexible circuit 2 will be described in detail later.

Hereinafter, the connection structure between the casing 210, the holder 220, and the flexible circuit 2 will be described in detail.

Fig. 8 is a schematic view showing the connection structure between the casing 210 and the flexible circuit 2 in detail; Fig. 9 is a schematic view showing the connection structure between the casing 210 and the holder 220 in detail.

First, the connection structure between the housing 210 and the flexible circuit 2 will be described.

The housing 210 is formed with an inner surface defining a flexible circuit housing portion 211, and an inner surface thereof is convexly formed with a locking protrusion 213.

The locking projections 213 are formed at the left and right end portions of the inner surface to face one surface of the flexible circuit 2 housed in the flexible circuit housing portion 211.

The locking projection 213 may be formed to cover at least one surface of the locking portion 2a of the flexible circuit 2. Referring to the drawing, the locking portion 2a is formed to protrude toward both sides of the flexible circuit 2, and the locking projection 213 can cover the upper surface of the locking portion 2a.

According to the above configuration, the locking portion 2a is caught by the locking projection 213, and the movement of the flexible circuit 2 is restricted. Thereby, the locking projection 213 can restrict the flexible circuit 2 from being drawn out from the flexible circuit housing portion 211.

The inner surface of the housing 210 is formed with an inclined surface 214. The inclined surface 214 is formed to protrude obliquely upward and extends to the locking projection 213. According to the above configuration, the flexible circuit 2 moves along the inclined surface 214 and can be easily inserted into the flexible circuit housing portion 211, and can be guided in such a manner that the locking portion 2a of the flexible circuit 2 can be caught by the locking projection 213.

According to the above configuration, when the flexible circuit 2 is inserted into the flexible circuit housing portion 211, the flexible circuit 2 moves along the inclined surface 214 of the housing 210, and the locking portion 2a of the flexible circuit 2 is stuck by the locking projection 213 of the housing 210. The soft circuit 2 can be easily inserted into the housing 210, and the extraction of the flexible circuit from the housing can be limited during the assembly of the connector.

Next, a connection structure between the holder 220 and the housing 210 will be described.

The holder 220 is disposed to cover one surface of the flexible circuit 2 and the locking protrusion 213 to prevent the flexible circuit 2 from being drawn out from the flexible circuit housing portion 211 and configured to be received in the flexible circuit housing portion 211 to be coupled and fixed to Housing 210.

To this end, the holder 220 includes a plate body portion 221 and a holder fastening portion 222.

The plate body portion 221 is formed in a rectangular shape so as to cover at least a part of one surface of the flexible circuit 2 provided in the flexible circuit housing portion 211.

Specifically, the first locking groove 215a is firstly locked by the holder first inclined surface S1 that is obliquely projected toward the inner side of the flexible circuit housing portion 211 and the holder that protrudes toward the outer side of the flexible circuit housing portion 211. The protrusion ST1 is formed.

The first inclined surface S1 of the holder guides the movement of the holder 220 so that the locking hook 222' can be inserted into the first locking groove 215a, and at the same time, the holder fastening portion 222 can be pressed and elastically deformed inward.

When the holder 220 passes the first inclined surface S1 of the holder, the holder fastening portion 222 is moved outward by the restoring force to be caught by the holder first locking projection ST1.

Thereby, the holder 220 can be moved downward, and the locking hook 222' can be inserted into the first locking groove 215a.

The second locking groove 215b may be spaced apart from the lower portion of the first locking groove 215a, and may be formed on the left and right inner side walls of the flexible circuit housing portion 211, respectively.

Referring to the drawings, the second locking groove 215b is formed by a second inclined surface S2 that is obliquely projected toward the inner side of the flexible circuit housing portion 211 and a second locking portion that protrudes toward the outer side of the flexible circuit housing portion 211. The protrusion ST2 is formed.

The second inclined surface S2 of the holder disengages the locking hook 222' from the first locking groove 215a by an external force applied in one direction (for example, the case where the drawing is pressed downward), and by holding The fastening portion 222 presses the inside to elastically deform.

When the holder 220 passes the second inclined surface S2 of the holder, the holder fastening portion 222 is moved outward by the restoring force to be caught by the holder second locking projection ST2.

Thereby, the holder 220 can be moved downward, and the locking hook 222' can be inserted into the second locking groove 215b.
