Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a connector with a lock lever, and more specifically, to a lock lever of a type in which the lock levers are swingably arranged at the left and right ends of the connector. The present invention relates to the improvement of a connector with a connector.

[Prior Art] Hereinafter, in this specification, the "neutral surface of the connector" means an imaginary surface extending in the connecting direction of the connector (corresponding to the axial direction of the cable) and parallel to the row of the contacts arranged in parallel. Say. Both sides of the center line of the contact along the plane are referred to as “left and right”, and the directions toward the neutral plane are “inside” and the directions are “outside”.

The connector with a lock lever generally has a cable side connector, a board side connector, and a lock lever for connecting and disconnecting these connectors. The lock levers are arranged at the left and right ends of the board-side connectors so as to be swingable in the direction of the neutral plane, and the respective connectors are brought into contact with and separated from each other by operating the lock levers with a finger.

The connector with a lock lever is roughly divided into one with a lock lever on the connector on the cable side,
It is classified into the type in which the lock lever is arranged on the board side connector.

In the case of a connector in which a lock lever is arranged on the cable side connector, as shown in FIGS. 8 and 9, a support shaft 67 provided at the end of the cable side connector 61 in a direction orthogonal to the neutral plane. A lock lever 65 is swingably installed on the. This lock lever 65 has a release projection 69 on the connection surface side.
The locking projection 71 is provided on the side opposite to the connection surface, and the operation portion 73 is provided further on the side opposite to the connection surface. The detachment protrusion 69 faces the detachment protrusion 75 formed on the board-side connector 63,
The lock protrusion 71 faces the lock portion 77 of the board-side connector 63. The board-side connector 63 is provided with a plurality of conductive contacts 83.

In the case of the connector in which the lock lever is arranged on the board side connector, as shown in FIGS. 10 and 11, the lock lever 65 is attached to the support shaft 67 similarly provided at the end of the board side connector 63.
Is arranged to be swingable. The lock lever 65 has a release projection 71 on the connection surface side and a lock projection 69 on the opposite connection surface side.
And further has an operation unit 73 in the vicinity thereof. The lock projection 69 faces the lock projection 81 formed on the cable side connector 61, and the release projection 71 faces the connection surface of the cable side substrate 63.

[Problems to be solved by the invention] By the way, in the case of a connector in which a lock lever is arranged on a board side connector, in order to disengage both connectors 61 and 63, lock levers 65 at both ends of the connectors 61 and 63 are to be disconnected. It is necessary to open it in the left-right direction as shown by the chain double-dashed line, but it is difficult to perform this work with one hand, and the operability is poor.

To disconnect the connectors 61 and 63 from the connector with the lock lever on the cable side connector,
It suffices to close the lock levers 65 at both ends of 61, 64 in the left-right direction as shown by the chain double-dashed line. Therefore, unless the distance between the left and right lock levers 65 is extremely large, it is possible to work with one hand, and there is no particular problem in terms of operability.

However, due to its structure, the locking protrusion 71 of the lock lever 65
Is protruding from the support shaft 67 to the board side connector 63,
Both ends of the board-side connector 63 are occupied by the lock lever 65. For this reason, there is an inconvenience that there is not enough room for providing another structure such as a substrate fixing structure.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a connector with a lock lever which has excellent operability and can sufficiently secure a room for providing another structure on the board-side connector.

[Means for Solving the Problems] According to the present invention, a first connector, a second connector fitted to the first connector so as to be contactable and separable via a connection surface, and the first connector described above. In a connector with a lock lever including a pair of lock levers arranged at the ends of the lock lever, the lock lever is supported by a spindle fixed to the end of the first connector in a direction orthogonal to the neutral plane. The lock lever includes a first releasing protrusion formed near the support shaft, an operating portion formed on the side opposite to the connecting surface of the first connector, the first releasing protrusion and the operating portion. And a first locking projection that is formed to protrude outwardly between the second connector and the second connector that faces inward to engage with the first locking projection in the groove formed in the connection surface. The protruding second locking protrusion and the first detaching member A second detachment protrusion formed in the groove to engage the protrusion,
When the first locking projections are disengaged from the second locking projections by operating the operation sections so that they approach each other and rotating the pair of lock levers about the support shaft, A connector with a lock lever is obtained in which the second detaching protrusion is arranged at a position pushed by the detaching protrusion.

[Operation] When the lock lever is opened to the left and right, the locking projection engages with the locking projection of the board-side connector to connect both connectors, and when the lock lever is closed, the disconnecting projection disconnects the board-side connector. Push the projecting part to disconnect both connectors.

[Embodiment] FIG. 1 shows an embodiment of a connector with a lock lever according to the present invention.

The connector with a lock lever shown in FIG. 1 has a cable side connector (first connector) 1 and a board side connector (second connector) 2 that comes in contact with and separates from the cable side connector 1. The cable side connector 1 is provided with a pair of lock levers 4 at left and right ends of the cable connector 1 in the longitudinal direction. A large number of contacts 3 are arranged in parallel on the side opposite to the connection surface of the board-side connector 2.

FIG. 2 shows a state in which the lock lever 4 is arranged on the cable side connector 1. At the end of the cable side connector 1,
An ear portion 11 is formed, and the ear portion 11 is provided with a support shaft 5 orthogonal to the neutral plane. A lock lever 4 having a substantially triangular shape is supported on the support shaft 5 at its apex.

The position of the support shaft 5 is set closer to the cable-side connector 1 than the connection surface with the board-side connector 2.

The lock lever 4 has a detachment protrusion (first detachment protrusion) 42 in the vicinity of the support shaft 5, and an operation portion 43 at the end on the side opposite to the connection surface. Further, a locking protrusion (first locking protrusion) 41 protruding outward is formed at a middle position between the detaching protrusion 42 and the operating portion 43.

Preferably, a small positioning protrusion 44 is formed on the detaching protrusion 42 so as to protrude outward, and a pair of recesses are appropriately formed in the cable-side connector 1 correspondingly. That is, when these are engaged with each other, a click feeling is given to the swing of the lock lever 4, and the lock lever 4 is positioned at the open position and the closed position. However, instead of this, a pair of small projections may be provided above and below in the figure with the lock lever 4 sandwiched between the ears 11 of the cable side connector 1 for positioning.

3 and 4 show an example of the board-side connector 2 connected to the cable-side connector 1 as described above by the lock lever 4. The board-side connector 2 has a large number of conductive contacts 3 arranged side by side on the side opposite to the connection surface for supporting, and a large groove 15 is formed on the connection surface. The rising portion 21 formed by the groove portion 15 is formed with a locking projection (second locking projection) 22 protruding inward. These locking projections 22 are attached to each connector 1, 2
In such a connected state, it is arranged to engage with the locking projection 41 of the lock lever 4. Further, a disengagement column body (second disengagement protrusion) 23 is formed in the groove portion 15, and this column body 23 faces the disengagement protrusion 42 of the lock lever 4 when the connectors 1 and 2 are connected. It is arranged like this.

FIGS. 5 and 6 show a state in which the respective connectors 1 and 2 are connected. In the figure, the solid line shows the lock lever 4 in the locked state,
The chain double-dashed line shows the lock lever 4 in the detached state.

In the locked state, the locking protrusion of the lock lever 4
41 engages with the locking projection 22 of the board-side connector 2 to keep the connectors 1 and 2 connected. To disconnect the connectors 1 and 2, push the operating part 43 with your finger and
Is closed as shown by the chain double-dashed line, the lock lever 4
The locking protrusion 41 of is the locking protrusion 22 of the board side connector 2.
As the detachment projection 42 pushes the column body 23 of the board-side connector 2 to the side opposite to the connection surface,
2 separate from each other. The pair of lock levers 4 is an operation unit.
By manipulating each of the parts 43 so that they approach each other, the support shaft 5 is rotated.

FIG. 7 shows another example of the connector with a lock lever, which replaces the columnar body 23 in the above-described embodiment and inwardly projects from the side wall defining the groove portion 15 of the board-side connector 2 (second connector). A detachment projection) 24 is provided. The disengagement protrusion 24 is arranged so as to be engaged with and pushed by the disengagement protrusion 42 of the lock lever 4 which swings when the connectors 1 and 2 are disengaged.

[Effects of the Invention] As described above with reference to the embodiments, when disconnecting each connector, the lock levers at the left and right ends of the connector can be closed with fingers, so that work can be performed with one hand except in special cases. Operability is very good.

In addition to this, since the locking protrusion of the lock lever is arranged on the side opposite to the connecting surface with respect to the support shaft, the structure is such that the space at both ends of the board-side connector is not invaded at all. Therefore, the left and right ends of the board-side connector can be freely used for a fixed structure or the like.
