Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an improvement of a connection device for video equipment.

[Known technology]

FIG. 1 is a schematic perspective view of a conventional video set, in which 1 is a tuner, 2 is a VTR body, 3 is a front cover, and 1a is a connector cord. In conventional video equipment connection devices, the tuner connector was completely fixed in order to determine the connection position between the VTR connector on the VTR body 2 side and the tuner connector on the tuner 1 side. . When connecting the VTR main body 2 to the tuner 1, press the VTR main body 2 in the direction of arrow C from the other end to the end on the connector installation side where the VTR main body 2 is attached to the tuner 1. I was trying to connect. In order to remove the VTR main body 2 from this state, the VTR main body 2 could not be removed unless it was pressed in the direction of arrow D, opposite to the above-mentioned pressing direction, from the end side of the connector attachment position. In addition, when the front side of the VTR main body 2 is lifted at the A position, a load is placed on the connector section, resulting in poor contact and damage.

[Purpose of the invention]

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a connection device for video equipment that is easy to connect and disconnect and can prevent damage to the connector and poor contact.

[Summary of the idea]

The video equipment connection device of this invention is connected to a tuner.
The VTR main body is attached separably and the tuner and the connector of the VTR main body are formed so as to be connectable, and when the engaging member of the VTR main body is inserted and guided, the guide groove provided on the tuner and the guide groove are connected. The protrusion is pressed by the weight of the VTR body placed on the tuner, and the connector holder of the tuner is attached to the VTR.
A connecting rod formed to lock the connector holder at a position facing the VTR main body connector of the main body, and a tuner connector of the connector holder rotatably attached to the VTR main body connector are press-connected to the VTR main body connector. The connector holder is provided with a spring that biases the connector holder to rotate.

[Embodiment of the invention] Hereinafter, the connection device for video equipment of the present invention will be explained using one embodiment and referring to Figs. 2 to 4, with the same parts as the conventional one denoted by the same reference numerals and the explanation of the structure of the same parts omitted. . 2 is a plan view of the tuner with the VTR main body 2 removed, FIG. 3 is a sectional view taken along the - arrow in FIG. 2, and FIG. 4 is a front view of FIG. 2. Chuyuna 1
The mounting part of the VTR body 2 has one end (rear side)
A connector holder 4 is rotatably attached to the
On the other end side (front side), there is a guide groove 1b into which a foot (engaging member, not shown) formed on the back side of the VTR main body 2 is inserted and guided, and a guide groove 1b to make it easy to insert fingers when holding the VTR main body. An escape groove 1c is provided.
The connector holder 4 is rotatably attached via a fulcrum rod 4c, and is rotated counterclockwise via a torsion spring 4b in the direction of arrow B where the tuner connector 8 contacts the VTR main body connector 9 shown in FIG. Forced. Reference numeral 4a indicates a guide rib formed on the tuner 1 so as to stop the rotation of the connector holder 4 at a position of 90 degrees with respect to the mounting surface of the VTR main body 2 of the tuner 1, and 4d indicates a connection cord. Chiyuna 1's
On the back side of the VTR main body 2 mounting surface, a protrusion 5 is fixed at one end so as to protrude onto the VTR main body 2 mounting surface, and the other end is formed so as to face the contact portion 10 of the connector holder 4. A connecting rod is rotatably attached via a fulcrum 11 and urged to rotate clockwise by a torsion spring 6.

FIG. 5 shows a state in which the VTR main body 2 is placed on the upper surface of the tuner 1, and the protrusion 5 of the connecting rod 7 is pressed by the weight of the VTR main body 2, and the connecting rod 7 resists the tension of the spring 6 and moves counterclockwise. The end of the rotated connecting rod 7 faces the contact portion 10 of the connector holder 4, and the clockwise rotation of the connector holder 4 is prevented. By pushing it in the direction of arrow E, tuner connector 8 and VTR main body connector 9 are connected.

FIG. 6 shows a state in which when removing the VTR main body 2 from the state in which the VTR main body 2 is connected as shown in FIG. Therefore, the contact portion 10 is released and the connector holder 4 becomes free to rotate and moves in the same manner as the VTR main body 2. That is, when removing the VTR main body 2, the displacement of the VTR main body 2 after inserting a finger into the relief 1c of the tuner 1 until the end of the connecting rod 7 comes off from the contact part 10 of the connector holder 4 is determined by the spring 4b.
The connector holder 4 is within the range in which it can be rotated by the tension, and thereafter, it comes to rotate integrally to the state shown in FIG. Therefore, poor contact and damage can be prevented without applying excessive force to the connector holder 4.

In this way, the video equipment connection device of this embodiment is
Since the VTR body is configured to be mounted on the tuner, it can be removed from the rear side of the set without pushing in the direction of arrow D in Figure 1 when removing the VTR body, and the connector can be contacted using spring pressure. By doing so, it is possible to prevent damage to the connector and poor contact during removal without applying excessive force to the connector portion, and therefore, operability can be improved.

[Effect of idea]

As described above, the video equipment connection device of the present invention is easy to connect and disconnect, prevents damage to the connector and poor contact, and has the effect of improving operability.
