Abstract
Description
Technical Field
[0001] The utility model relates to an insert core installation structure, in particular to an insert core module fixing frame. Background Art
[0002] Ferrules are widely used in the field of data transmission, especially in the field of optical fiber communication technology. As an important part of the optical fiber connector, the ferrule precisely connects the two end faces of the optical fiber and aligns the axes of the two optical fibers accurately, so that the light energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent and the impact on the system is minimized. In order to prevent the ferrule core from being affected by the external environment during use, a shell is usually set outside the ferrule core to protect the internal circuit.
[0003] The fixing structure of the existing plug-in module mostly adopts the method of directly fixing and locking two shells. Although the shells of the two shells fit as closely as possible, there will still be some gaps, and it is extremely easy for water and dust to accumulate at the locking position of the two shells. This gap not only easily causes water to enter the interior of the frame, but also easily causes dust to be retained. If water brings dust into the fixed frame, it will greatly affect the normal use of the plug-in module.
[0004] Therefore, this case aims to provide a plug-in module fixing frame, which can not only effectively protect the fitting gap between the two shells, but also seal the connection position of the two shells to prevent water and dust from being retained at this position, thereby making the two shells more integrated after being locked. Utility Model Content
[0005] The utility model provides a core insertion module fixing frame, which can effectively solve the above problems.
[0006] The utility model is achieved in this way:
[0007] A plug module fixing frame, comprising: an upper connection cover and a lower mounting seat, the lower mounting seat is locked on a mounting surface, a threaded hole is provided on the lower mounting seat, a through hole is provided on the upper connection cover, and a screw rod penetrating the through hole and cooperating with the threaded hole is provided, and the plug module fixing frame also includes:
[0008] A double-position sealing structure, wherein the upper connecting cover and the lower mounting seat are provided with a giveway groove in the directions facing each other, and the first connecting ear seat and the second connecting ear seat are respectively provided on both sides of the upper connecting cover and the lower mounting seat, and the double-position sealing structure comprises a first sealing strip arranged on the giveway groove in the upper connecting cover, and a second sealing strip is arranged on the giveway groove in the lower mounting seat, an outward expansion structure is arranged in the first connecting ear seat, and a spring sheet structure is arranged in the second connecting ear seat, and when the upper connecting cover is connected to the lower mounting seat, the first sealing strip is pressed against the second sealing strip, and the outward expansion structure squeezes the spring sheet structure and makes the spring sheet structure overflow from the outer side surface of the lower mounting seat.
[0009] As a further improvement, the spring sheet structure is glued to the inner spring sheet in the second connecting ear seat, and the outer side of the inner spring sheet is glued to the outer side of the inner spring sheet. When the outward expansion structure is pressed down, the outward expansion structure applies pressure on the inner spring sheet and causes the outer spring sheet to overflow.
[0010] As a further improvement, the outward expansion structure includes a pressing plate fixedly connected to the middle section of the outer portion of the screw rod, and when the screw rod is rotated downward, the pressing plate is pressed against the inner elastic plate.
[0011] As a further improvement, a plurality of springs are provided on the top of the pressing sheet, and the tops of the springs are locked to the top of the inner side of the first connecting ear seat.
[0012] As a further improvement, the through hole is an elliptical hole.
[0013] The beneficial effects of the utility model are:
[0014] Although the existing plug-in fixing structure has a simple seal, in fact, the fit between the upper connecting cover and the lower mounting seat is not strict, and there are often gaps in the connecting area, allowing water and dust to accumulate. Therefore, the utility model sets a double-position sealing structure. First, the position of the upper connecting cover and the lower mounting seat is preliminarily sealed by the first sealing strip and the second sealing strip to prevent water and dust from directly entering the interior of the fixed frame. Secondly, when the screw is matched with the threaded hole, the height of the outward expansion structure decreases, which will directly press the spring structure on the second connecting ear seat. After the screw is completely locked, the spring structure will overflow, directly making up for the height difference between the first connecting ear seat and the second connecting ear seat and the upper connecting cover and the lower mounting seat, so that the sealing degree of the first connecting ear seat and the second connecting ear seat reaches the same as the sealing degree of the upper connecting cover and the lower mounting seat, achieving an IP68 waterproof effect.

[0023] In the description of the present invention, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0024] Reference Figure 1 to Figure 6 As shown, a plug module fixing frame includes: an upper connecting cover 1 and a lower mounting seat 2, the lower mounting seat 2 is locked on the mounting surface, a threaded hole 21 is opened on the lower mounting seat 2, a through hole is opened on the upper connecting cover 1 and a screw 22 that penetrates the through hole and cooperates with the threaded hole 21, and the plug module fixing frame also includes: a double-position sealing structure, the upper connecting cover 1 and the lower mounting seat 2 are both provided with a clearance groove in the direction facing each other, and the upper connecting cover 1 and the lower mounting seat 2 are respectively provided with a first connecting ear seat 4 and a second connecting ear seat 4 on both sides. The connecting ear seat 5, the double-position sealing structure includes a first sealing strip 31 arranged on the give-way groove in the upper connecting cover 1, a second sealing strip 32 is arranged on the give-way groove in the lower mounting seat 2, an outward expansion structure 6 is arranged in the first connecting ear seat 4, and a spring structure 7 is arranged in the second connecting ear seat 5. When the upper connecting cover 1 is connected to the lower mounting seat 2, the first sealing strip 31 is pressed against the second sealing strip 32, and the outward expansion structure 6 squeezes the spring structure 7 and makes the spring structure 7 overflow the outer side surface of the lower mounting seat 2.
[0025] In the existing structure, a fixed frame often includes two parts, namely the upper connecting cover 1 and the lower mounting seat 2 in this embodiment. The upper connecting cover 1 and the lower mounting seat 2 together constitute a structure that can accommodate the plug assembly, and the upper connecting cover 1 and the lower mounting seat 2 can achieve closed and disassembled states.
[0026] In this embodiment, the upper connection cover 1 and the lower mounting seat 2 are initially matched with each other through the matching of the screw rod 22 and the threaded hole 21 .
[0027] Although the existing plug-in fixing structure has a simple seal, the matching between the upper connection cover 1 and the lower mounting seat 2 is not strict, and there is often a gap in the connection area, allowing water and dust to accumulate. Therefore, this embodiment uses a double-position sealing structure to firstly perform a preliminary seal on the position of the upper connection cover 1 and the lower mounting seat 2 through the first sealing strip 31 and the second sealing strip 32 to prevent water and dust from directly entering the interior of the fixing frame;
[0028] Furthermore, when the screw 22 cooperates with the threaded hole 21, the height of the outward expansion structure 6 decreases, which will directly press the spring structure 7 on the second connecting ear seat 5. After the screw 22 is completely locked, the spring structure 7 will overflow, directly making up for the height difference between the first connecting ear seat 4 and the second connecting ear seat 5 and the upper connecting cover 1 and the lower mounting seat 2, so that the sealing degree between the first connecting ear seat 4 and the second connecting ear seat 5 reaches the same as the sealing degree between the upper connecting cover 1 and the lower mounting seat 2, achieving an IP68 waterproof effect.
[0029] In this embodiment, the spring sheet structure 7 is glued to the inner spring sheet 71 in the second connecting ear seat 5, and the outer side of the inner spring sheet 71 is glued with the outer spring sheet 72. When the outward expansion structure 6 is pressed down, the outward expansion structure 6 applies pressure on the inner spring sheet 71 and causes the outer spring sheet 72 to overflow. The inner spring sheet 71 and the outer spring sheet 72 are actually glued into an integral structure. Therefore, when the inner spring sheet 71 is pressed, it will directly squeeze the outer spring sheet 72 and cause the outer spring sheet 72 to move outward. The outer spring sheet 72 will fill the entire gap between the first connecting ear seat 4 and the second connecting ear seat 5 due to the squeezing effect of the first connecting ear seat 4 and the second connecting ear seat 5.
[0030] The outward expansion structure 6 that cooperates with the spring sheet structure 7, specifically, includes a pressing sheet 61 fixedly connected to the middle section of the outer portion of the screw rod 22. When the screw rod 22 is rotated downward, the pressing sheet 61 is pressed against the inner spring sheet 71. There is no need to separately set a positioning structure for the pressing sheet 61. The pressing sheet 61 only needs to be tightened into place, and the pressing sheet 61 will automatically reach its preset position. In order to prevent the position of the entire screw rod 22 from requiring separate alignment when locking, a plurality of springs 62 are provided on the top of the pressing sheet 61. The top of the spring 62 is locked to the top of the inner side of the first connecting ear seat 4. Since the pressing sheet 61 is fixed on the screw rod 22, the position of the screw rod 22 is always not easy to change, thereby reducing the difficulty of cooperation.
[0031] Furthermore, the through hole is an elliptical hole.
[0032] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
