Description

Technical Field

[0001] This application relates to the field of camera equipment technology, and specifically to a reflective fiber optic light guide assembly. Background Technology

[0002] When using a waterproof camera housing, during video recording, the flash signal inside the camera needs to be transmitted to the flash unit located outside the waterproof housing to control the flash action.

[0003] In existing technology, a light guide is connected to a waterproof housing and then to a flash unit, transmitting the flash signal from the camera to the flash unit. Since the camera's flash signal propagates perpendicular to the waterproof housing, the connector of the light guide is also perpendicular to the housing. This perpendicularity can easily cause the light guide to enter the lens's field of view, affecting the image quality. Furthermore, when mounting external lenses, the protruding connector caused by its perpendicularity to the housing may interfere with the installation of different lenses, potentially preventing lenses from being mounted on the waterproof housing. Utility Model Content

[0004] This application provides a reflective fiber optic light guide assembly, which aims to solve the problems of existing technology where light guides enter the lens field of view and affect lens installation.

[0005] In one embodiment, a reflective fiber optic light guide assembly is provided, comprising:

[0006] Light guide;

[0007] A connector for connection to a flash unit, the connector being connected to the light guide;

[0008] A connector for connecting to the outer casing, the connector having a first slot for the light guide to be inserted; the connector also having a second slot communicating with the first slot;

[0009] A reflective sheet; the reflective sheet is fixed in the second slot, and the plane of the reflective sheet is set at 135° with the extension direction of the first slot.

[0010] The outer shell is waterproof and has a slot for connecting to the connector. The plane of the reflector is set at a 45° angle to the direction of the camera flash signal propagation, so the flash signal is reflected at a 90° angle on the reflector and then enters the light guide.

[0011] In one embodiment, the connecting seat is fixedly connected to a pressure block by bolts, the pressure block covering the first slot and abutting against the light guide.

[0012] In one embodiment, the connector has a boss; both the first and second slots are disposed on the boss. The boss is used to engage and limit the connector within the housing.

[0013] In one embodiment, the second card slot is inclined, and the plane containing the inner wall of the second card slot is set at 135° to the extending direction of the first card slot, and the reflective sheet is attached and fixed to the inner wall of the second card slot.

[0014] Specifically, an opening is provided on one side of the second slot, that is, the opening is located on the side edge of the boss.

[0015] In one embodiment, the connecting seat has a protrusion located on the edge of the connecting seat and on the opposite side of the pressure block.

[0016] In one embodiment, the central side of the protrusion has a recess.

[0017] In one embodiment, there are two first card slots, which are arranged in parallel to each other.

[0018] In one design, the bottom of the second slot is arc-shaped.

[0019] In one embodiment, the connector includes a plug for connecting to a flash socket and a sealing portion for sealingly connecting to the flash socket. The shape of the sealing portion matches the shape of the flash socket, and the sealing portion has a sealing groove for a sealing ring to be inserted into. The sealing groove is arranged circumferentially around the sealing portion.

[0020] Specifically, the number of sealing grooves is two that are spaced apart from each other.

[0021] The beneficial effects of this application are:

[0022] By setting a reflector at a 135° angle, the flash signal is transmitted to the guide light through the reflector. Due to the reflector, the light inlet of the guide light can be parallel to the housing, thus reducing the amount of guide light entering the lens's field of view. At the same time, since the light inlet of the guide light is parallel to the housing, it avoids the protrusion of the guide light when it is connected to the housing, thereby preventing the guide light from protruding and affecting the lens installation.

[0036] This application proposes improvements and innovations, and presents the following embodiments.

[0037] In some implementations, please refer to Figures 1 to 4 A reflective fiber optic light guide assembly is provided, comprising:

[0038] Light guide 1;

[0039] Connector 2 is used to connect to the flash unit, and connector 2 is connected to the light guide 1;

[0040] The connector 3 is used to connect with the outer shell. The connector 3 has a first slot 31 for the guide light 1 to be inserted into. The connector 3 also has a second slot 32 that communicates with the first slot 31.

[0041] Reflector 4; The reflector 4 is fixed in the second slot 32, and the plane of the reflector 4 is set at 135° with the extension direction of the first slot 31.

[0042] The outer shell is waterproof and has a slot for connecting to the connector 3. The plane of the reflector 4 is set at a 45° angle to the direction of the camera flash signal propagation. Therefore, the flash signal is reflected at 90° on the reflector 4 and then enters the light guide 1.

[0043] By setting a reflector 4 at a 135° angle, the flash signal is transmitted to the guide light 1 through the reflector 4. Due to the setting of the reflector 4, the light inlet of the guide light 1 can be parallel to the outer shell, thus reducing the number of times the guide light 1 enters the lens field of view. At the same time, since the light inlet of the guide light 1 is parallel to the outer shell, the protrusion caused by the guide light 1 when connected to the outer shell is avoided, thereby avoiding the situation where the guide light 1 protrudes and affects the lens installation.

[0044] In one embodiment, the connector 3 is bolted to a pressure block 33, which covers the first slot 31 and abuts against the light guide 1. By setting the pressure block 33, the light guide 1 and the connector 3 can be more securely connected together.

[0045] In one embodiment, the connector 3 has a boss 34; both the first slot 31 and the second slot 32 are disposed on the boss 34. The boss 34 is used to lock and limit its position within the housing. The boss 34 ensures that the first slot 31 and the second slot 32 have sufficient depth and guarantees the strength of the connector 3. Furthermore, when the connector 3 is connected to the housing, the boss 34 engages with the connection opening of the housing, reducing the protrusion of the connector 3 relative to the housing and preventing interference with lens mounting.

[0046] In one embodiment, the second slot 32 is inclined, and the plane containing the inner wall of the second slot 32 is at a 135° angle to the extending direction of the first slot 31. The reflective sheet 4 is attached and fixed to the inner wall of the second slot 32. Inclining the second slot 32 and fitting it with the reflective sheet 4 reduces the size of the second slot 32 and ensures the structural strength of the connecting seat 3.

[0047] Specifically, the second slot 32 has an opening on one side, that is, the opening is located on the side edge of the boss 34. The opening on one side of the second slot 32 facilitates the installation and removal of the reflector 4.

[0048] In one embodiment, the connector 3 has a protrusion 35 located on its edge and opposite to the pressure block 33. The protrusion 35 facilitates the user's separation of the connector 3 from the housing. Simultaneously, the protrusion 35 provides sufficiently deep mounting holes for bolts, improving the stability of the pressure block 33 connected to the connector 3.

[0049] In one embodiment, the central side of the protrusion 35 has a recess 36. The recess 36 allows for easy insertion of a hand to facilitate separation of the connector 3 and the housing. Furthermore, the recess 36 reduces the weight of the connector 3, saving material usage.

[0050] In one design, there are two first card slots 31, arranged parallel to each other. Using two first card slots 31 increases the number of flash units that can be connected, thus improving shooting results.

[0051] In one design, the bottom of the second slot 32 is rounded. The rounded bottom of the second slot 32 facilitates the slotting process of the second slot 32.

[0052] In one embodiment, connector 2 includes a plug 21 for connecting to a flash socket and a sealing part 22 for sealingly connecting to the flash socket. The shape of the sealing part 22 matches the shape of the flash socket, and a sealing groove is provided on the sealing part 22 for a sealing ring 23 to engage. The sealing groove is arranged circumferentially around the sealing part 22. The sealing part 22 effectively seals the flash socket, preventing water from entering and affecting the normal operation of the flash. Connector 2 is used to transmit the flash signal to the flash lamp.

[0053] Specifically, there are two sealing grooves spaced apart from each other. Two sealing grooves can improve the sealing effect.

[0054] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this utility model.
