Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a connector device into which a conductor such as a flexible cable is inserted and connected.

[Prior Art] FIG. 7 shows an example of a connector device to which a flexible cable is connected. The flexible cable 10 has a plurality of conductors 71 arranged in parallel on the surface of a thin plate-like insulator 72,
The conductor 71 is further covered with an insulator 13. When connecting such a cable 10 to the connector device 80, the insulation 72, 73 at the end of the cable is removed to expose the conductor 11.

Inside the housing 81 of the connector device 80, a plurality of connection terminals 82 are arranged at intervals corresponding to the arrangement of the conductors 71 of the cable 10. Each connection terminal 82 is formed of a highly elastic metal plate, and has a base 83 . and an elastic contact portion 84 extending from this base portion 83 and a bottle portion 8
5. The tip 84a of the elastic contact portion 84 is connected to the base 8.
It is in contact with 3. The bottle part 85 protrudes outside the housing 81, and its tip 85a is inserted into a through hole of a printed circuit board, for example, and connected to an electric circuit of the board.

When connecting the cable 70 to the connector assembly [80, the conductor 71 of the cable is pushed between the tip 84a and the base 83 of the elastic contact portion 84 of the connection terminal 82. FIG. 8 shows the state in which the cable 70 is inserted into the connector device 80, and the conductor 71 is connected to the bent portion 84b of the contact portion 84.
is pressed against the base 83 by the elastic restoring force of the connecting terminal 8
A connection is made between the two.

In such a connector device, the cable is inserted by forcing the conductor itself to force open the space between the tip and base of the elastic contact portion. Therefore, when the conductor is inserted, it pushes up the tip 84a of the elastic contact portion of the connecting terminal, and is therefore rubbed by this tip 84a. Therefore, the surface of the conductor is bent, and strong force is required to push open the tip 84a, which may deform the conductor itself. Furthermore, when the number of conductors and therefore the number of connection terminals is large, the necessary pushing force is added to each terminal, and a large insertion force is required as a whole, making it difficult to perform the connection work efficiently. be.

[Problems to be Solved by the Invention] Therefore, it is an object of the present invention to provide a connector device in which the insertion force of the cable is small and the conductor of the cable is not subjected to any loss.

[Means for Solving the Problems] That is, in the connector device according to the present invention, a connecting terminal is arranged in an opening of a housing, a movable member to be inserted into this opening is prepared, and the movable member is inserted into the opening of the housing. A cam protrusion having a width and length is formed on the member at the end thereof to be inserted into the opening, and the elastic contact portion is pressed by the cam protrusion when the movable member is inserted into the opening of the housing. so that a gap is formed into which a conductor can be inserted. Further, the length and height of the cam protrusion are selected so that the movable member comes into contact with and presses the elastic contact portion at an initial stage when the movable member is inserted into the opening of the housing.

[Operation] In the connector device configured as described above, when the movable member is inserted into the opening of the housing to a depth thereof, the cam protrusion pushes open the elastic contact portion and connects the conductor such as a cable. form a space in which the material can be inserted. When the conductor is inserted, by completely inserting the movable member, the engagement between the cam protrusion and the elastic contact portion is released, and the elastic contact portion comes into elastic contact with the conductor of the inserted cable. be.

[Embodiment] A connector device according to an embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows a connector assembly M10 and a cable 50 connected thereto, and the connector assembly 10 is composed of two parts: a housing 20 and a movable member 30.

The housing 20 is provided with an opening 21, and a plurality of connection terminals 40 are arranged in parallel inside this opening. As shown in an enlarged view in FIG. 2, the connection terminal 40 is provided at one end with an elastic contact portion 41 folded back into a figure 7 shape. This elastic contact portion 41 can press the conductor 51 of the cable 50 inserted into the housing 20 in a direction perpendicular to its insertion direction. In this embodiment, the tip of the elastic contact portion 41 is further curved inward, and is configured to contact the conductor 51 at the top surface 41a of this curved surface. At the other end of the connection terminal 4o,
A bottle portion 42 extending to the outside of the housing 20 is formed.

The tip 42a of the bottle portion 42 can be connected to a printed circuit board or the like.

The movable member 30 is formed with a frame portion 32 having an opening 31 corresponding to the opening 21 of the housing 20, and a flat body portion 33 extending from the bottom side 32a of the frame in a direction perpendicular to the frame. ing. The main body portion 33 is configured to have a size that allows it to be inserted into the opening 21 of the housing. A surface 34 of the main body portion 33 on the side of the frame portion 32 is a flat surface. However, on the surface of the main body part 33 on the side to be inserted into the housing 20, a plurality of cam protrusions 35 extending toward the frame part 32 from the end part 33a on the housing side are arranged at regular intervals. The bottom surface of the elongated passageway 36 between each cam projection 35 is flush with the flat surface 34 of the body portion 33 . The spacing between the cam projections 35 is selected such that the tips of the plurality of conductors 51 of the cable 50 are located in each passage 36, respectively.

A wall 37 higher than the cam projection 35 is formed on the surface of each cam projection 35 . When the movable member 30 is inserted into the housing 20, this wall 37 becomes a partition wall that is located between two adjacent connection terminals 400 in the housing and isolates these connection terminals 40 one by one.

FIG. 3 shows a portion of the distal end of the movable member 30 attached to the housing 20.
The state in which it is inserted into the opening 21 is shown. As shown in this figure, the bending angle 41b of the elastic contact portion 41 of the connection terminal 40 is such that when no force is applied to the connection terminal 40, the contact surface 41a is the upper surface of the cam protrusion 35 of the movable member. 35a, and is selected so that when the conductor 51 is placed on the flat surface 34, it can come into contact with the surface with sufficient pressing force.

In the connector device 1o configured in this way, when the movable member 30 is further pushed into the housing 20, the contact surface 41 of the elastic contact portion 41 of the connection terminal 40 is moved as shown in FIG.
When the upper surface 35a of the cam projection 35 of the movable member is used, the conductor 51 can be inserted below the contact surface 41a without touching the connection terminal 40 at all. Thereafter, when the movable member 30 is pushed further, the upper surface 35a of the cam protrusion 35 touches the contact surface 41.
At the same time as it finishes passing under a, the contact surface 41a presses the conductor 51 due to the elastic force of the elastic contact portion 41, and comes into contact with the conductor 51 as shown in FIG. electrical connections are made.

Since the conductor 51 is not moved between the time when the insertion of the conductor shown in FIG. 5 is completed and the time when the insertion of the movable member shown in FIG. 6 is completed,
When the contact portion 41 and the conductor 51 are in contact with each other, they do not move relative to each other, and therefore there is no J between the contact portion and the conductor.
No IJ rubbing occurs and the conductor is not damaged. In addition, the contact portion 41 is pressed by the cam protrusion 35 provided on the pressing member, and the conductor 51 is inserted while a sufficient space (in the case of this embodiment, the passage 36) is secured for the insertion of the conductor 51. The force may be very small.

From both sides of the frame of the movable member, the two frames 38 formed on both sides of the main body, together with the two protrusions 23 and 24 formed on the side surfaces of the housing, prevent the movable member from separating from the housing. Used for correction. That is, one side 39 of the frame 38 close to the housing is connected to two protrusions 23.2.
4 prevents the movable member 30 from separating from the housing 20, and by engaging with the protrusion 23, the movable member can be fixed to the housing.

Further, in the case of the above embodiment, a cutout 43 is provided at the tip of the contact portion, and the conductor 51 having a circular cross section is pressed by the portions on both sides of this cutout portion, but the shape of the cross section of the conductor and the contact portion The shape of is not limited to this. Further, the conductor connected to this connector device is not limited to a bottle-shaped conductor, but may be a twisted wire, and can be used not only as a flexible cable but also as a general conducting wire.

Further, the cam projections do not need to be provided on both sides of the groove 36 that serves as a passage for the conductor 51, but may be provided on one side. Also, the space for inserting the conductor does not need to be a passage between the cam protrusions; for example, each cam protrusion may be formed to be located directly below the contact terminal, and each cam protrusion may have a tunnel-like passage. The conductor may be inserted into the passage while the elastic contact portion of the connection terminal is in contact with the surface of the cam projection.

[Effects] As described above, the connector device according to the present invention includes a housing in which a connecting terminal having an elastic contact portion that makes elastic contact with a conductor is fixed, and a movable member inserted into this housing. is formed with a cam protrusion so that when the movable member is inserted into the opening of the housing, the cam protrusion presses the elastic contact portion to ensure a gap in which the conductor of the cable can be inserted. . Therefore, by inserting the conductor of the cable into this gap, the conductor can be inserted without touching the elastic contact portion. Therefore, the insertion force is very small, and the conductor is not damaged by friction with the contact portion.
