Problems solved by technology

However, in the vicinity of the HDMI terminal configured in this way, when a screwdriver (driver, Phillips screwdriver) is used to assemble a substrate or the like with a screw, the front end of the screwdriver is likely to deviate from the screw and slide into the concave portion.
Therefore, there is such a problem that assembly is difficult and there is a possibility of damaging the function of the expensive HDMI terminal.

Embodiment Construction

[0049] Hereinafter, embodiments embodying the present invention will be described with reference to the drawings. In the embodiment, a projector mounting jig for mounting a control board (first board) and an interface board (second board) to a frame as a board mounted on a projector will be described with reference to the drawings as an example. . This projector is a projector equipped with an HDMI terminal (recessed terminal). It splits the light (beam) from the light source into red, blue, and green color lights, and the split lights are emitted to the liquid crystal panels for the respective colors. A method of synthesizing optical images modulated for each color light on a liquid crystal panel to generate a color image.

[0050] FIG. 1 is a perspective view showing the appearance of a projector. FIG. 2 is a perspective view showing the appearance of the projector viewed from the bottom of the rear. As shown in FIG. 1 , the projector 1 has a substantially rectangular par...

Abstract

The invention provides a clamp (50) used for assembling a projector, which does not damage the function of concave terminal, such as HDMI etc., and can be easy for assembling and fixing. The clamp (50) is provided with a support pin (53) supporting a control baseplate (20) and a frame (30), a protecting board (61) used for protecting the concave part (22a) of an HDMI terminal (22), the guide hole (62) of a rotating tool (70) which is arranged at the protecting board (61) and is used for guiding a stopping screw thread piece (28) to be used for fixing a stopping screw thread hole (25) and the frame (30) and a shaft support part (63) for a rotary shaft to support the protecting board (61). Under the condition that the frame (30) is supported in an approximately vertical direction, the protecting board (61) is departed from the position of the HDMI terminal (22). Under the condition that the clamp (50) rotates and supports the frame in an approximately horizontal direction, the protecting board (61) rotates and protects the HDMI terminal (22) so as to cover over the HDMI terminal (22).

Description

technical field [0001] The present invention relates to a projector assembling jig for assembling a concave terminal such as an HDMI terminal included in a projector. Background technique [0002] Conventionally, in a projector, as disclosed in Patent Document 1, a main board and an interface board are arranged substantially at right angles to effectively utilize an internal space. In further detail, both the main substrate and the interface substrate are fixed on the frame. Furthermore, a connector or the like for connecting to an external device is fixed to a frame surface or the like substantially parallel to the interface board while conducting and connecting to the main board. [0003] Patent Document 1: JP-A-2004-138911 [0004] In recent years, HDMI terminals, which have a smart function of mutual recognition between connectors, have gradually begun to be installed on projectors and the like. The HDMI terminal has a concave portion for inserting a convex connection...
