Detailed Description
The preferred mechanism and method of movement of the present invention will be further described with reference to the drawings and detailed description below, in which the fiber optic connector moving parts are specific to various types of fiber optic connectors for securing optical fibers.
As shown in fig. 2 to 19, an optical fiber connector tool includes a base 1, a detection end 2, a first movable member 3 and a second movable member 4.
The base 1 is provided with a groove 1-1 for fixedly arranging the optical fiber connector.
The groove 1-1 is mainly used for fixing the optical fiber connector main body 5-1 in a disassembled state in field installation, and the optical fiber connector in the disassembled state is provided with various types of groove 1-1 as shown in fig. 1, for example, the groove 1-1 matched with the outline of the optical fiber connector main body 5-1 in the disassembled state is arranged, so that the optical fiber connector main body 5-1 is fixed;
The optical fiber connector body 5-1 can be fixed by arranging a convex clamping point, clamping position or concave fixing hole position on the optical fiber connector 5, and arranging a corresponding structure such as a groove, clamping position or short column on the clamping point, clamping position or hole position by the groove part 1-1; the fixing can also be realized according to some structural characteristics of the optical fiber connector, for example, a boss 5-6 is naturally formed at the tail part of some optical fiber connector main bodies 5-1, a step 5-7 is necessary in structural design, and a clamping groove or a protruding ridge matched with the corresponding boss can be correspondingly designed in the groove part 1-1. Or the optical fiber connector main body 5-1 is provided with a small fixing hole which does not affect the main body structure, and the groove part 1-1 is correspondingly provided with a convex clamping pin which extends into the small fixing hole so as to fix the relative position of the optical fiber connector 5.
The direction in the slot 1-1 in which the fixation is required for the different connectors:
For the push-tube type optical fiber connector, the push-tube type optical fiber connector is characterized in that the optical fiber connector moving part of the push-tube type optical fiber connector 5 is pushed to advance or retreat in the axial direction so as to lock the optical fiber, so that the groove part 1-1 of the optical fiber connector tool has the main function of fixing the optical fiber connector 5 to be fixed in the longitudinal direction or the axial direction; meanwhile, because the bayonet of the optical fiber connector movable piece of the push tube type optical fiber connector is transversely arranged, even when the first step 3-1 of the first movable piece 3 is inserted into the optical fiber connector movable piece, the optical fiber connector tool can not influence the pushing of the optical fiber connector movable piece in the longitudinal direction even if the optical fiber connector 5 transversely slides in the groove part 1-1.
For the U-shaped clip spring type optical fiber connector, because the first step 3-1 of the key is flat when the key is inserted into the optical fiber connector 5, and the bayonet parts of the optical fiber connector 5 and the key are arranged along the longitudinal direction or the axial direction, in order to wedge the first step 3-1 of the first movable part 3 of the optical fiber connector tool into the bayonet of the movable part of the optical fiber connector, namely, the slot bayonet between the slot body and the cover body, the first step 3-1 is also designed along the longitudinal direction; so theoretically, as long as the bayonet is long enough, after the first step 3-1 of the first movable member 3 of the optical fiber connector fixture is inserted into the optical fiber connector movable member, the insertion of the optical fiber into the optical fiber connector 5 is not affected even if the optical fiber connector 5 slides back and forth in the longitudinal direction, so the groove portion 1-1 can be mainly used for limiting the lateral position of the optical fiber connector.
For box-laying type optical fiber connector, the optical fiber connector is locked by mainly inserting the optical fiber connector movable piece, namely the inserting piece or the box cover, into the optical fiber connector, so that the inserting piece or the box cover can be pressed in only by the step of the first movable piece.
The above is a possible way of limiting the fixation of the fiber optic connector by the groove portion 1-1, but the optimal fixation for three fiber optic connectors is still fixed both laterally and longitudinally.
The detection end 2 is arranged on the base body 1-1 and provides a light source for detecting the position of the optical fiber inserted into the optical fiber connector through the self or an externally connected light-emitting part. The detection end 2 is detachably integrated with the optical fiber connector 5 by a cylindrical structure combined with the optical fiber connector, namely, the detection end sleeve 2-2.
The main function of the detecting end 2 is to confirm that the optical fiber is inserted into the correct position when the optical fiber is inserted into the optical fiber connector 5, and then to lock the optical fiber by the movable member of the optical fiber connector. Because the optical fiber or the bare fiber is very fragile, if the pin of the optical fiber connector 5 is plugged only by the end cover, the operator needs to feel whether the optical fiber is inserted into the end of the pin by hand of the operator or whether the inserted optical fiber is bent, so that the optical fiber is easy to be excessively inserted or the optical fiber is broken when being inserted, and other adverse effects are easily caused, so that the position of the optical fiber is conveniently checked. Specifically, the principle is as follows:
the detection end 2 emits a light source, the light source emits to the end face of the optical fiber connector 5, if no optical fiber is inserted, the contact pin of the optical fiber connector 5 is in a hollow state, the light source is not coupled into the optical fiber, at the moment, the light source is in a scattering state due to radiation, and the brightness of light leaking out of the contact pin in the radial direction is higher; when the optical fiber is inserted into the end part of the contact pin, the optical fiber can be coupled with the light source if the optical fiber reaches the end part of the contact pin, and at the moment, most of light is transmitted due to the light guide characteristic of the optical fiber, so that the brightness of the contact part of the light source and the contact pin can be obviously reduced, whether the position of the optical fiber is in place can be judged through visual brightness, excessive insertion of the optical fiber or insufficient insertion length of the optical fiber is not easy to cause, and the optical fiber is particularly suitable for field installation.
The detecting end 2 may be only one housing for configuring the detachable connection head 12, and the form of the scheme is that another detachable connection head 12 specially providing a light source is configured, and the detachable connection head 12 may be another optical fiber connector specially providing a light source, and the optical fiber connector is directly connected with the light source through an optical fiber or through a tail fiber, that is, the optical fiber connector 5 fixed in the groove part 1-1 of the present patent is provided with a detecting light source through external light source luminescence. The design adopts the existing light source tool which is arranged on the present site for detecting whether the optical cable is good or not, the light source tool comprises a detachable connector 12, the detachable connector 12 is provided with a light-emitting part which is in butt joint with the optical fiber, and the condition of the optical fiber to be detected can be detected initially by inputting the light source into the optical fiber to be detected; therefore, the detection end 2 of the patent can be just a shell which is in butt joint with an existing light source tool on site, so that the reasonable utilization of the existing tool is realized.
Meanwhile, the detection end 2 can also be a self-contained light source, the structure of the detection end is similar to that of the existing portable light source, a shell of the detection end is provided with a switch and a light source assembly, a light outlet point of the light source assembly is arranged at a position opposite to a fiber channel of an optical fiber to be connected with the optical fiber connector limited on the base, and the light source assembly is powered by a battery of the light source assembly, so that the light source can be controlled to be started by a button in a serial connection mode. The light source assembly outputs a light source through the end part of the optical fiber positioned in the light source assembly and is opposite to the optical fiber in the optical fiber connector on the base body 1, and the scheme is equivalent to arranging the light source in the shell of the detection end, so that the position condition of the optical fiber connector 5 inserted into the optical fiber can be detected by using the light source of the tool.
When the optical fiber connector is configured on the base 1, the detection end 2 can be configured on the base 1 in a plug-in mode through the plug-in part from the outside, and the detection end can be matched with a boss matched with the channel only through the channel, as shown in fig. 2, 7 and 8, and meanwhile, the optimal mode provided by the patent is as follows: the detection end 2 is movably arranged on the seat body 1 through a pin shaft 2-1. Although the detection end 2 may be completely fixed, the optical fiber connector 5 may be damaged by being forcibly locked in such a manner, and the structure is not necessarily firm, which is disadvantageous in detecting the position of the optical fiber by the light source. For a general optical fiber connector 5, a gap is formed between the head part of the contact pin and the shell, so that the head part of the detection end 2 is provided with a detection end sleeve 2-2 matched with the gap, the detection end sleeve 2-2 is inserted into the head part of the optical fiber connector 5, so that the detection end 2 and the optical fiber connector 5 are connected into a whole, and the detection end 2 also follows the position of the optical fiber connector 5 to be fixed in a state that the optical fiber connector 5 is fixed in the groove part 1-1, and the optical fiber connector 5 is driven to move onto the base 1 along a fixed track by the action of the pin shaft 2-1 and combined with the groove part 1-1, so that the optical fiber connector 5 is accurately configured in the groove part 1-1.
The first movable member 3 is movably provided to the base 1 and is movable to be combined with or separated from the groove portion 1-1, and in a state that the first movable member 3 is combined with the groove portion 1-1 to restrict the optical fiber connector 5, the first movable member 3 is inserted through the first step 3-1 of the first movable member 3 or is inserted through the first step 3-1 and pushes the optical fiber connector movable member for fixing the optical fiber.
As shown in fig. 13, wherein the first step 3-1 of the first movable member 3 is flat, the first step 3-1 of the first movable member is laterally inserted into the push-tube type optical fiber connector; as shown in fig. 11 and 12, or inserted longitudinally into a clip-spring fiber optic connector.
The manner in which the first movable member 3 is movably disposed can be distinguished by the state: one of which is reversible and the other of which is detachable, specifically:
The turnover structure can be as shown in fig. 2, one side of the groove part 1-1 is provided with a suspended movable shaft lever 1-5, one side of the first movable part 3 is provided with a first shaft lever sleeve 3-2 which is matched with the movable shaft lever 1-5, so that turnover can be performed; meanwhile, as shown in fig. 9, the structure of the first shaft lever sleeve 3-2 matched with the movable shaft lever 1-5 can be correspondingly changed into a hinge structure 6, the hinge structure 6 can be formed by overturning a hinge part, one side of the hinge can be combined with the first movable part 3 into a whole, and the other side of the hinge is fixed on one side of the groove part 1-1 of the seat body 1, so that the hinge structure 6 can be used for overturning.
The detachable structure can be that one side or two sides of the groove part 1-1 are provided with movable shaft rods 1-5, as shown in fig. 11, one side or two sides of the corresponding side of the first movable part 3 are provided with strip-shaped clamping grooves 7 corresponding to the movable shaft rods 1-5, and the strip-shaped clamping grooves can be elastically clamped on the movable shaft rods 1-5 through the material of the first movable part 3, so that the first movable part 3 is fixed and detached; meanwhile, as shown in fig. 10, or a groove guide rail 8 is arranged on one side or two sides of the groove part 1-1, an opening part 9 is arranged on the guide rail, the opening part can be positioned on the top or the side part, as shown in fig. 13, a guide rail sliding part 10 which is downwards extended and matched with the groove guide rail is arranged on one side or two sides of the corresponding first movable part 3, the guide rail sliding part 10 is inserted into the guide rail at the opening part 9, and the first movable part 3 is pushed to enable the guide rail sliding part to be coupled with the groove guide rail, so that the detachable structure is realized.
For push-tube type optical fiber connectors, the length of the movable shaft rod 1-5 ensures that the first movable part 3 can move the optical fiber connector movable part positioned on the base body 1 to a locking position when moving, or the length of the guide rail 8 ensures that the first movable part 3 can move the optical fiber connector movable part positioned on the base body 1 to the locking position when moving.
The locking position refers to a position where the optical fiber is locked and fastened in the optical fiber connector by moving the optical fiber connector moving part from one end to the other end after the optical fiber is inserted into the optical fiber connector.
For the push-tube type optical fiber connector 5, since it is required to be inserted into the optical fiber connector movable member at the first step 3-1 of the first movable member 3 and push the optical fiber connector movable member to lock the optical fiber to the optical fiber connector 5, the first movable member 3 is required to be capable of being turned over and slid back and forth at this time.
