Description

The present invention relates to a type of connector. Especially flexible substrates (Flexible Printed
This is a type of connector that can effectively prevent circuit board (FPCB).

A flexible substrate is a basic component that must not be missing in electronic products. The combination has different characteristics when applied to an electric circuit of a certain “operation function”. For this reason, the industry has developed flexible substrates that are light in weight, thin in thickness, and can be rotated. The flexible board can further utilize the size and shape of the space according to the product, and can perform wiring in a three-dimensional space. Then, electronic, communication and military products that match the characteristics of light, thin and small must be used.

Since the flexible board is light and thin, and has a characteristic that it can be rotated, as shown in FIG. 1, it is connected to the knotted end of the flexible board 1 'through the other connector 2' when it is connected to the electric circuit. Increase the strength of the machine. The connector 2 'is provided with a plug hole 21' in the main body so that the terminal 22 'can be fixed. Further, the flexible substrate 1 ′ extends into the plug hole 21 ′, and the contact arms of the flexible substrate 1 ′ and the terminal 22 ′ are brought into close contact with each other according to the fastener 23 ′, and the flexible substrate is connected from the terminal 22 ′. An electrical circuit in which 1 'and a connector 2' are arranged is interconnected. Also, when the flexible board 1 'operates and moves together with the associated electric circuit, the flexible board 1' always forms a certain degree of pulling action between the connectors 2 ', resulting in a phenomenon of separating from each other; In the structure of the terminal 22 ′ at 2 ′, a convex portion 222 ′ is installed on one side where the contact arm 221 ′ and the flexible substrate 1 ′ are in contact with each other. Therefore, the flexible substrate 1 ′ extends between the contact arm 221 ′ and the fastener 23 ′ when the fastener 23 ′ of the connector 2 ′ is still hung on the contact arm 221 ′, and the fastener 23 ′ is directed toward the contact arm 221 ′. When restrained, the contact arm 221 'cooperates in producing an appropriate elastic deformation. This is useful for holding and positioning the fastener 23 '. Using the elastic action of the contact arm 221 ′, the convex portions 222 ′ are held down toward the flexible substrate 1 ′. Then, it can be expected that the bonding strength between the flexible substrate 1 ′ and the terminal 22 ′ is increased.

However, the learning connector 2 ′ forms a rotational spacing action from the support arm 223 ′ of the terminal 22 ′ to the fastener, and when the fastener 23 ′ is completely closed, the terminal 22 ′ is convex of the contact arm 221 ′. Although the suppressing action between the portion 222 ′ and the flexible substrate 1 ′ is formed, the suppressing action is constituted only by the elastic action of the contact arm 221 ′. Therefore, the suppressing action on the flexible substrate 1 ′ is still insufficient. It is. In addition, the elastic action of the contact arm 221 'decreases with time, and the suppression action formed by the contact arm 221' and the flexible substrate 1 'decreases. Then, in an unpredictable situation, the connection between the flexible substrate 1 'and the electric circuit may be poor, and the flexible substrate 1' may slip.

Based on the needs of flexible board connectors, the present inventor improves the above-mentioned drawbacks caused by the known connectors, and creates a connector to which the flexible board is applied, and provides it for industrial use.

The technical means adopted by the present invention is similarly provided with a support arm extending into the slot at the base of the terminal, and the fastener is provided with pivots at both ends to connect the connector body. A vacant hole is installed at a position relative to the support arm of the terminal, and the inner wall of the vacant hole floats and protrudes. The front end of the support arm of this terminal extends into the vacant hole in an arc shape. There are recesses that can cooperate with the compression part and the pivot that can be made, for example, when the fastener is completely closed, the pivot of the fastener just faces the recess of the support arm. Therefore, the arc-shaped pressure-resisting part and the concave part at the front end of the support arm closely approach each other to suppress the space and suppress the fastener from being pushed out, effectively preventing slippage of the flexible board. it can. That is the main purpose of the present invention.

As a secondary purpose of the present invention, the terminal structure is inserted into the plug hole of the connector so that it can be connected to the flexible board, and a guiding arm is further provided at the front end of the contact arm of the terminal. The guide arm has a first convex part and a second convex part of fixed length protruding from the inner wall of the flexible board and plug hole, respectively, and the flexible board is located between the contact arm and the fastener by the action of the guide arm. To accurately guide the extension. When the fastener is closed, it uses the appropriate elastic deformation action of the contact arm and the guide arm to help close and localize the fastener. In addition, when the fastener is completely closed, the first convex part of the guide arm and the flexible board are restrained and gripped, and the second convex part and the inner wall of the plug hole are leaned against each other. The Therefore, it is possible to limit the reverse deformation of the guide arm, and it is also possible for the first convex portion to maintain the suppressing action on the flexible substrate. If it does so, the strength of a flexible substrate and a terminal will be raised greatly, and the slip of a flexible substrate can be prevented effectively.

Another object of the present invention is that another bullet can be installed in the plug hole of this connector, and the bullet and fastener pivots are mutually suppressed, and the contact position between the bullet and pivots. After the fastener is closed, a concave fastener and a convex fastener are installed, and the pacing of the fastener is further enhanced by the concave fastener and the convex fastener. Then, when the elastic deformation of the contact arm and the support arm of the terminal is lost, the fastener does not yet receive the reversing rotational force, so that the fastener does not pop out and stably suppresses the flexible substrate and the terminal. Can give.

As another object of the present invention, a buffer area is formed between the arm surface of the support arm of the terminal and the wall surface of the plug hole, and when the flexible substrate is thicker, the contact arm is subjected to elastic deformation. In addition, the supporting arm can make two elastic deformations in the buffer area, and can avoid the fastener from being released and torn.

Install a fastener that can suppress each other, and in this terminal, there are a contact arm and a support arm inserted into the inside of the plug hole on the base, and a compression part and a recess are installed at the front end of the support arm. Further, it is characterized in that it is connected to the main body by installing pivots at both ends of the fastener, and a vacant hole is provided at a position corresponding to the support arm of the terminal, and a rotation pivot is provided on the inner wall of the vacant hole.
Further, according to the present invention, a guiding arm is installed at the front end of the contact arm of the terminal as described in claim 2, and the guiding arm protrudes and extends to the inner wall of the flexible substrate and the plug hole, respectively. There is a fixed first convex part and a second convex part, and the elastic part of the front end of the support arm of this terminal is in a tortuous state, so it can be extended into the vacant hole of the fastener, has an elastic deformation action, and The rotating pivot portion of the fastener is characterized by floating and protruding.
Further, according to the present invention, when the compression portion and the fastener at the front end of the support arm of the terminal are closed, the rotation portion of the fastener rotates according to the arc degree of the recess, and the fastener is completely When closing, the pressure-reducing part and the concave part closely suppress the rotation center of the fastener so as to suppress it and create a spacing after the fastener is hung, and it cannot be reversed unless an acting force is applied.
