Abstract
The utility model discloses an infrared touch screen frame structure, which comprises four frames with circuit boards inside thereof are arranged at the periphery of a touch screen; a right angle connecting component is arranged between two adjacent frames; positive guide rail shafts are respectively arranged at two ends of the right angle connecting component; and sliding guide rail grooves matched with the positive guide rail shafts are formed in the frames. The infrared touch screen frame structure has the advantages of firm structure, easy installation, good stability of connected integral structure and good appearance and visual effects.
Description
Technical field
The utility model relates to a kind of framed structure of infrared touch panel.
Background technology
The employed framed structure that is used for fixing the touch-screen framework of infrared, circuit board for receiving in existing infrared touch panel, it is made up of the frame that is provided with along touch-screen four limits, circuit board is set respectively in each frame, corresponding infrared ray Transmit-Receive Unit is set on it.The dislocation mode is adopted in splicing between adjacent two frames at four jiaos of places of touch-screen usually, and promptly one of them frame is pressed on the termination of adjacent frame.Framed structure is compact, not attractive in appearance inadequately like this, need repeatedly cut frame, step complexity during installation.
Summary of the invention
The purpose of this utility model provides a kind of framed structure of infrared touch panel of simple in structure, easy for installation and good looking appearance.
Technical solution of the present utility model is: a kind of framed structure of infrared touch panel, comprise that inside is provided with the frame of circuit board, between two adjacent described frames, be respectively equipped with the right angle coupling assembling, the two ends of this right angle coupling assembling are respectively equipped with positive lead rail axis, in described frame, be provided with the rail plate groove that cooperates with positive lead rail axis, and this rail plate groove is parallel with described circuit board.
The positive lead rail axis at coupling assembling two ends, right angle is inserted respectively in the interior rail plate groove of adjacent frame, adjacent like this two frames are pegged graft by the right angle coupling assembling and are spliced into one, easy for installation, need not tool using cutting, the right angle coupling assembling can use the material consistent with the frame profile, touch-screen framed structure overall appearance degree height, good visual effect.
Be respectively equipped with the bonder terminal of electrical connection at the two ends of described right angle coupling assembling, be respectively equipped with the connector row pin that cooperates with bonder terminal on the circuit board in described frame, by bonder terminal the circuit board in adjacent two frames is coupled together, the convenient installation, also conveniently be made into simultaneously standard component, reduce the operation of field fabrication.
On described positive lead rail axis, be provided with screw, be used for the right angle coupling assembling is fixed on frame, can improve the firmness of connection.
The utility model has the advantages that: sound construction, install easily, connect back one-piece construction good stability, the outward appearance visual effect is good.

Embodiment
Embodiment:
Consult Fig. 1-5, a kind of framed structure of infrared touch panel comprises the frame 1 of one-body molded hollow, and its inside is provided with the circuit board 4 that has infrared ray Transmit-Receive Unit 3, and frame 1 is provided with optical filter 2, is used for protecting infrared ray Transmit-Receive Unit 3.During installation, circuit board 4 is last, and infrared ray Transmit-Receive Unit 3 is down, and the precision of touch recognition can be improved in the gap that can reduce infrared ray Transmit-Receive Unit and touch screen surface like this.Between two adjacent described frames 1, be provided with right angle coupling assembling 6, the two ends of this right angle coupling assembling 6 are respectively equipped with positive lead rail axis 7, be respectively equipped with the rail plate groove 5 that cooperates with positive lead rail axis 7 in the frame 1, and this rail plate groove 5 is parallel with described circuit board 4.
Be respectively equipped with the bonder terminal 9 of electrical connection at the two ends of right angle coupling assembling 6, be respectively equipped with the connector row pin 10 that cooperates with bonder terminal 9 on the circuit board 4 in frame 1, the circuit board in adjacent two frames 44 be electrically connected by bonder terminal 9.
The positive lead rail axis 7 of right angle coupling assembling 6 is provided with screw 8, can use screw to be fixed on the frame 1.
Above-listed detailed description is specifying at one of the utility model possible embodiments, this embodiment is not in order to limit claim of the present utility model, allly do not break away from the equivalence that the utility model does and implement or change, all should be contained in the claim of this case.
