[Industrial applications]

 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a connector having a connecting portion configured to be rotatable.

[0002]

[Prior Art]

 Conventionally, a so-called swing connector having a connecting portion configured to be rotatable as shown in FIG. 4 has been known.

The swing connector 1 has a stator 5 made of an insulating synthetic resin having a cylindrical shaft portion 2 and an insulating synthetic material having bearing portions 4 a and 4 b engaging with both ends of the shaft portion 2. The rotor 3 is made of resin. The rotor 3 is A with respect to the stator 5. ₁ -A₂It can be rotated in any direction. A rotor contact 7, which is a copper-molded product and extends inside the rotor 3 and projects from the rotor 3, is arranged around the shaft portion 3.

Further, the copper molded product contact 8 provided so as to project from the lower end of the stator 5 in the drawing extends inside the stator 5 so as to come into contact with the rotor contact 7 around the shaft 2. It is configured. Therefore, even if the rotor 3 and the stator 5 rotate with respect to each other, the electrical connection between the rotor contact 7 and the stator contact 8 is maintained.

Therefore, for example, by connecting the rotor contact 7 protruding from the rotor 3 to a circuit board by soldering, and the stator contact 8 protruding from the stator 5 to another circuit board by soldering, two circuit boards are formed. Are electrically connected to each other in a rotatable state.

The stator contact 8 is connected to the circuit board by soldering, and the rotor contact 7 on the rotor 3 side is connected to a socket connector from the outside to connect to the socket connector. The device and the circuit board are connected.

[0007]

[Problems to be solved by the device]

 However, according to the conventional swing connector described above, the rotor contact and the stator contact are configured to protrude from the rotor or the stator, and the circuit board is connected to each of the protruding contacts, or the rotor contact is, for example, a socket from the outside. A connector (2 mm pitch is standard) is attached and connected.

Therefore, there is a problem that it is difficult to reduce the pitch of the rotor contacts, and particularly, in the case of a socket connector having a multi-pin structure, a considerable mounting force is required and workability is low. Further, when both contacts are directly soldered to the circuit board, there is a drawback that it is difficult to replace the circuit components arranged on the circuit board connected via the swing connector.

In view of the above points, an object of the present invention is to provide a connector that can be easily connected to the outside, has high workability, and has a narrow pitch.

[0010]

[Means for Solving the Problems]

 The above problem can be solved by configuring as follows.

That is, the first conductive member arranged on the fixed portion and the first conductive member arranged on the rotating portion rotatably connected to the fixed portion are brought into contact with the first conductive member to be electrically connected to each other. In a connector having a second conductive member to be connected, the connector is provided by being engaged with a rotating portion, and the second conductive member and a third conductive member from the outside are brought into contact with each other to be electrically connected. Therefore, a holding member for detachably holding the third conductive member is provided.

[0012]

According to the present invention having the above-described structure, the third conductive member from the outside is detachably held by the holding member to maintain the electrical connection with the second conductive member, and the second conductive member is maintained. And electrically connect to the first conductive member via the.

【Example】

 1 and 2 are vertical cross-sectional views of an essential part of one embodiment of the present invention, and FIG. 3 is a three-sided view of one embodiment of the present invention, in which (A) is a plan view and (B) is a front view. Figure, (C) is a side view.

In FIG. 3, a swing connector 11 is generally referred to as a rotor 13 (rotating member) which is rotatably connected to a stator 12 (fixed portion) and a stator 12 in the A ₁ -A ₂ direction in FIG. And the moving part).

The rotor 13 is a holding member provided with the rotor mold 14 so as to be slidably engaged with the rotor mold 14 in the B ₁ -B ₂ directions in FIGS. 15 and a plurality of rotor contacts 17 which are the second conductive members arranged on the rotor mold 14.

The rotor mold 14 is a molded product made of an insulating PBT (polybutylene terephthalate) resin, the rotor cover 15 is a molded product made of an insulating nylon resin, and the rotor contact 17 is a copper alloy metal. Molded product is gold selective plated.

On the surface of the rotor mold 14 facing the rotor cover 15, a plurality of guide grooves 16 are formed in parallel with each other at an equal pitch of 1.25 mm, and the rotor contacts 17 are guided by the guide grooves 16. Further, bearing portions 19a and 19b having circular holes 18a and 18b, respectively, are formed at both left and right ends of the rotor mold 14 in FIGS.

The stator 12 is composed of a stator mold 20 which is a PBT resin molded product, and a stator contact 21 which is a first conductive member made of a copper alloy plated with gold selective. At both ends of the stator 12, screw-fastened portions 23a and 23b having circular holes 22a and 22b, respectively, are formed, so that the stator 12 can be screwed and fixed to, for example, a circuit board.

Further, the stator 12 is formed with a stopper 23 that projects rightward in FIG. 1C and restricts the rotational position of the rotor 13. Further, the stator 12 is formed with a cylindrical portion 24 extending in the left-right direction in FIG.

Cylindrical shaft portions 25 a and 25 b are formed on both left and right ends of the cylindrical portion 24 so as to project in the longitudinal direction of the cylindrical portion 24, and the shaft portions 25 a and 25 b are formed on the bearing portions 19 a of the rotor mold 14. The circular holes 18a and 18b formed in 19b are engaged and supported. As a result, the rotor 13 and the stator 12 are rotatably connected to each other.

On the circumferential surface of the cylindrical portion 24, a plurality of guide grooves 26 are formed in parallel with each other at an equal pitch of 1.25 mm 2, like the guide grooves 26. The guide groove 26 is provided with a stator contact 21 formed in a "U" shape as described later, and is configured to come into contact with the rotor contact 17 so as to be electrically connected thereto. The stator contacts 21 are further bent by 90 °, extend into the inside of the stator 12, and are arranged on the bottom surface 27 of the stator 12 in a staggered manner and protrude.

Next, the connection between the rotor contact 17 and the stator contact 21 and the connection between the rotor contact 17 and the outside will be described in detail with reference to FIGS. 1 and 2.

1 and 2 are longitudinal sectional views of the swing connector taken along the line I-I in FIG. 3, and FIG. 1 shows the rotor 13 rotating in the A ₁ direction (clockwise direction) in FIG. 2A and 2B show the rotor 13 rotated in the A ₂ direction (counterclockwise direction) in FIG. 2C.

In both figures, reference numeral 30 shows a known FPC (Flexible Printed Circuit Board) in which a copper foil is printed and formed on a base film, and the FPC 30 has the same pitch as the 1.25 mm pitch of the rotor contacts 17. Thus, a plurality of copper foils 31 which are third conductive members are arranged in parallel with each other. A space 32 is formed between the rotor cover 15 and the rotor mold 14, and a film-shaped FPC 30 is externally inserted into the space 32 as shown in the drawing.

The rotor contact 17 is arranged in the guide groove 16 of the rotor mold 14 as described above. As shown, the rotor contact 17 is molded so as to have an FPC-side convex portion 17a protruding toward the FPC 30 and a stator-contact-side convex portion 17b protruding toward the stator contact 17 at both ends.

The stator contact side convex portion 17 b is formed in a “U” shape of the stator contact 21 and abuts on a portion of the cylindrical portion 24 provided in the guide groove 26. Each of the protrusions 17a and 17b is made of a copper alloy having an elastic force, and is configured to have a function as a leaf spring for ensuring contact.

By the way, in FIG. 1, the state where the rotor cover 15 is pulled out in the B ₁ direction is shown by a solid line. When the rotor cover 15 is slid in the B ₂ direction and locked by the rotor mold 14 as shown in FIG. 2 (shown by the one-dot chain line in FIG. 1), the FPC 30 is tapered near the center of the rotor cover 15. It is pressed toward the rotor mold 14 by the step portion 15a formed on the.

As a result, as shown in FIG. 2, the FPC 30 is brought into contact with the FPC-side convex portion 17a of the rotor contact 17 to conduct electricity, and is sandwiched by the rotor mold 14 and the rotor cover 15 to maintain electrical connection. .. As a result, the FPC 30 comes into contact with the rotor contact 17 to conduct electricity, and the rotor contact 17 comes into contact with the stator contact 21 to conduct electricity.

As described above, by inserting the FPC 30 into the gap 32 between the rotor mold 14 and the rotor cover 15 and sliding the rotor cover 14 in the B ₁ direction, the stator contact 21 and the FPC 30 can be easily and surely connected. It is electrically connected via the rotor contact 17.

In this manner, the portion of the stator contact 21 that protrudes from the bottom surface 27 of the stator mold 20 is soldered and connected to a circuit board (not shown), so that, for example, a motor connected to one end of the FPC 30 not shown in the figure can be connected. Can be connected to a circuit board.

At this time, as described above, the rotor 13 is configured to be rotatable with respect to the stator 12, and the FPC 30 mounted on the rotor 13 is bendable as is well known. It is possible to pull out the FPC 30.

As described above, since the film-shaped FPC 30 is sandwiched by inserting the FPC 30 into the space 32 and sliding the rotor cover 15, the FPC 30 can be easily rotated without requiring excessive force regardless of the number of pins. It can be attached to 13.

Further, the FPC 30 can be easily removed from the rotor 13 by sliding the rotor cover 15 in the B ₂ direction, which results in high workability. Therefore, the parts arranged on the circuit board can be easily replaced by removing the FPC 30 from the rotor 13.

Further, in the present embodiment, the structure is not such that the socket connector is connected to the rotor 13 as in the conventional connector, but the structure is such that the FPC which can easily narrow the pitch can be connected. Therefore, although each contact has a 1.25 mm pitch configuration in the above-described embodiment, the contact pitch is not limited to this, and the swing connector 11 having a further narrowed pitch may be configured in response to higher density of the circuit board. Is also possible.

Further, although the FPC 30 is connected to the rotor 13 in the above-described embodiment, it may be a wiring member having a film shape or a flat plate shape and the conductive members arranged at the same pitch as the rotor contacts 16. However, it is not limited to the FPC, and it is conceivable to connect an FFC (Flexible Flat Cable; so-called tape electric wire) or the like, and the same effect as the above-described embodiment can be obtained.
