Description

[Detailed description of the invention] [Industrial application field] This invention is a connector, more specifically, a connector that connects electrical or electronic circuit terminals between devices,
The present invention relates to a connector for disconnecting and disconnecting, and particularly to a connector for simultaneously attaching and detaching a plurality of contacts and pins.

[Prior Art] Recently, with the remarkable development of electronics and its related technical fields, the number of terminals to be connected between the circuits of electric or electronic equipment applied to various devices has increased, and so-called It is becoming multipolar.

If the number of terminals to be connected is large in this way, the contact force between the terminals becomes strong, and there is a limit to the number of terminals. Therefore, in order to avoid this, so-called "zero force" is used, which is configured so that there is no friction between the contacts and pins of the connector when they are mated or disengaged.
are required.

However, the zero-force connector requires many two- or three-stroke actions to connect and disconnect, such as operating a lever, rotating a cam, and moving a slider. As described above, when the fitting operation of the connector becomes complicated, it takes time to attach and detach the connector, and there are many disadvantages such as making it difficult to fit the connector accurately.

[Purpose of the invention] Taking into account the problems mentioned above, the main purpose of this invention is very simply the so-called "one-touch"
The purpose is to provide a connector that can be connected and disconnected.

A further object of this invention is to provide a connector that can easily insert and remove multi-core terminals with low insertion force, has a simple structure, and can be fitted accurately.

[Structure of the invention] A preferred embodiment of this invention will be described with reference to the drawings. The socket 10 of the connector is a rectangular block made of an insulator. The socket 10 is formed with a plurality of rows and stages of cavities 16 extending parallel to each other at intervals from each other and extending from the front surface 12 to the rear surface 14, and contacts 18 are housed in the cavities 16.

The contact 18 is formed as an integral structure from an elastic thin metal plate commonly used in this type of connector, as shown in FIG. That is, the contact 18 is composed of a clamp portion 22 for tightening and attaching the base 20 and the conductor 21, a short contact piece 24 that branches into two, and a long contact piece 26. The short contact piece 24 and the long contact piece 26 are curved close to each other about the base 20 and extend forward.

When the contact 18 is accommodated in the cavity 16 of the socket 10, the short contact piece 24 of the contact 18
terminates inside the front face 12 of the socket 10, and the elongated contact piece 26 projects further outwardly from the front face 12.
As shown in FIG. 7, this contact 18 has a long contact piece 26 on the left side from the center when viewed from the front surface 12 of the socket 10, and a long contact piece 26 on the left side from the center and the long contact piece 26 on the right side from the center. Place it so that it protrudes to the right.

The upper and lower surfaces of this socket 10 close to the front surface are provided with narrow grooves 28 at positions parallel to the front surface 12, respectively.
is formed.

As shown in FIG.
A pair of laterally symmetrical drive plate members 30 are attached to the drive plate members 30 . Each drive plate member 30 is made of an insulator like the socket, and is mounted on the front surface of the socket 10 so that both drive plate members 30 can slightly slide relative to each other. That is, for this purpose, each drive plate member 30 has both upper and lower ends facing the front surface of the socket 10 protruding inward, and is fitted into the narrow groove 28 of the socket 10, as shown in FIGS. 3 and 5. It is formed into a protrusion 32 that is slidably fitted. To attach each drive plate member 30 to the socket 10, the protrusion 32 may be slightly opened outward and fit into the slot 28 of the socket 10.

Drive plate member 30 has an aperture 34 formed therein at a location that is aligned with cavity 16 of socket 10. The side edges 36 of the front surface 12 of the socket 10 are aligned so that the cavity 16 of the socket 10 and the opening 34 of the drive plate member 30 are aligned with each other when the pair of drive plate members 30 are mounted in the socket 10. An elastic member 40, such as a leaf spring, is disposed between the side end faces 38 of the drive plate member 30 and the opposite side end faces 38 of the drive plate member 30, and presses the pair of mounted drive plate members 30 in a direction toward each other. There is. Further, a stopper 44 is provided at the center of the front surface 12 of the socket 10 to prevent the adjacent end surfaces 42 of both drive plate members 30 from coming into contact with each other.
is formed to protrude. That is, when the pair of drive plate members 30 are attached to the front surface 12 of the socket 10, the drive plate members 30 are held against the stopper 4 by the elastic member 40.
4, the cavity 16 of the socket 10 and the opening 34 of the drive plate member 30 are aligned.

The opening 34 of the drive plate member 30 is provided with a pin, which will be described later.
It penetrates from the front surface 46 of the drive plate member 30 to the rear surface 48 so that when the pin 66 of the connector 60 is inserted, it penetrates and protrudes. On the rear surface 48 of the drive plate member, a partition defining adjacent openings 34 for the pins 66 is provided with a recess for receiving the protruding end of the long contact piece 26 protruding outwardly from the contact 18 attached to the socket 10. 50 are formed. Since the height of the recess 50 is greater than the height of the opening 34, the recess 50 is larger than the height of the adjacent opening 34.
A side wall 51 having a step difference above and below is formed, and the side edge of the long contact piece 26 engages with this side wall 51.

A lever 52 is attached to one end of the drive plate member 30 so as to extend rearward. Lever 52
can be constructed integrally with the drive plate member 30, or may be constructed separately. This lever 52 extends rearwardly along the side 54 of the socket 10 when the drive plate member 30 is installed in the socket 10. The side surface 54 of the socket 10 is provided with an outwardly projecting protrusion 56 near the front surface 12 of the socket 10, and when the drive plate member 30 is attached to the socket 10 as described above, the protrusion 5
6 contacts the inner surface of the lever 52 and acts to project the free end side of the lever 52 outward. An engaging portion 58 protruding outward from the surface of the lever 52 is provided at a position close to the free end side of the lever 52.

A pin is attached to the assembly of the socket 10 and the pair of drive plate members 30 described above as a mating member.
The connector 60 has a rear opening 62 as shown in FIG.
The socket 10 and the drive plate member 30 are fitted into this rear opening 62. A plurality of conductor pins 66 are fixed to the front wall 64 of the pin connector 60 so as to protrude toward the rear opening 62, and are aligned with the opening 34 of the drive plate member 34 attached to the socket 10. The forward portion of pin 66 that projects forward of front surface 64 connects to circuit conductors on other associated circuit boards (not shown), as is well known in the art.

Each side wall 68 of pin connector 60 includes:
An opening 70 is provided in which the engaging portion 52 can freely fit into the lever 52 of the drive plate member 30 when the pin connector 60 is fitted into the assembly of the socket 10 and the drive plate member 30. .

[Operations and effects of the invention] Since the connector of this invention is constructed as explained in detail above, one
When the pair of drive plate members 30 is installed, the elastic members 40 disposed between the opposite ends of the pair of drive plate members 30 and both ends of the socket 10 cause the drive plate members 30 to close together. The members 30 each have their adjacent end surfaces 42 connected to a stopper 4 provided at the center of the front surface of the socket 10.
4 and stop. Then insert the contact 18 into the empty space 16 from behind the socket 10.
When inserted, the short contact piece 2 of the contact 18
4 ends in the cavity 16 of the socket 10, and the long contact piece 26 projects forward from the cavity 16 and enters a recess 50 in the rear face of the drive plate member 30, forming a step with the opening 34 for the pin 66. Without contacting the side wall 51, the curved portions of the short contact piece 24 and the long contact piece 26 remain in close proximity to form an assembly disposed on the socket 10 and drive plate member 30.

The pins 66 are brought into contact with the contacts 18 by inserting the rear openings 62 of the pin connector 60 into the above assembly. That is, the opening 62 of the pin connector 60 is connected to the socket 10 and the drive plate member 3.
0 assembly, the pin connector 6
The side walls 68 of the socket 10 press the levers 52 of the pair of drive plate members 30 inwardly, and the levers 52 press against the socket 10.
actuated using the protrusion 56 of the side surface 54 as a fulcrum, and moves each of the driving plate members 30 so as to open toward the side edge 36 of the socket 10 against the force of the elastic member 40. Due to this movement, the portions of the long contact pieces 26 in the recesses 50 of the drive plate member 30 come into contact with the side walls 51, and further move slightly in the direction of the side edges 36 of the sockets 10, so that they approach each other. contact 18
The short contact piece 24 and the long contact piece 26 are opened.

In this state, the pin connector 60 is pushed in, so the pin 66 of the pin connector 60 fits between the open contact pieces 24 and 26 of the contact 18 without any resistance and with zero insertion force. can do.

As the pin connector 60 continues to be fitted, the protruding engaging portions 58 of the levers 52 of the pair of drive plate members 30 enter the openings 70 in the side walls 68 of the pin connector 60 and are pressed inward until then. The free end of the lever 52, which had been
0, the lever 52 operates using the protrusion 56 on the side surface 54 of the socket 10 as a fulcrum, and both drive plate members 30
are moved back toward the central stoppers 44, which are closer to each other. As a result, the long contact piece 26 of the contact 18 is released from the side wall 52, the contact 18 is restored by its own elasticity, and the curved portions of both the contact pieces 24 and 26 approach each other, and the contact piece 26 is inserted between them. The pin 66 is securely contacted.

The engaging portion 58 of the lever 52 of the drive plate member 30 fits into the opening 70 of the side wall 68 of the pin connector 60, which means that the engagement portion 58 of the lever 52 of the drive plate member 30 fits into the opening 70 of the side wall 68 of the pin connector 60. Acts as a lock. Therefore, the pin connector 60 fitted in this manner reliably maintains its fitted state, and there is no risk of it coming off even if vibration or other external force is applied.

To release pin connector 60 from the assembly of socket 10 and drive plate member 30, the free end of lever 52 is pressed to release drive plate member 3.
0 outward, pull out the engaging portion 58 of the lever 52 from the opening 70 in the side wall 68 of the pin connector 60, and pull the pin connector 60 forward.
The pin 66 can be freely and easily removed from the contact 18 without any resistance.

As can be fully understood from the above description, the connector of this invention allows the pin connector 60 to be fitted into the assembly of the socket 10 and the drive plate member 30 with great ease. It is a simple operation of fitting the rear opening 62 of 60 into the assembly. Further, when the contact 18 and the pin 66 are attached and detached, no resistance or friction is caused between the two. Further, after the pin connector 60 is connected to the assembly of the socket 10 and the drive plate member 30, there is no danger that the two may fall off due to vibration or other external force unless a particular removal operation is performed.

Moreover, this invention has the excellent effect of being economical in all respects, including assembly and manufacturing, because it does not require rotating members or devices unlike conventional zero-force mechanism connectors. It is something that has.
