Description

Technical Field

[0001] The present invention relates to the technical field of optical modules, and in particular to an optical module. Background Art

[0002] Currently, the commonly used unlocking methods for optical modules are straight-pull and rotary, which are relatively complicated. They are both exposed at the optical port of the module, taking up space, which can easily cause the rubber-coated pull ring to interfere with external parts such as fiber jumpers, tail sleeves, and dust plugs, making it inconvenient to plug and unplug and connect optical fibers. According to research, the tolerances and angles of the assembly fit between the sheet metal pull ring and the various components of the base are related to the stability of the unlocking function. Any slight error can easily lead to unlocking failure. Therefore, suppliers need to strictly control the process standards, and the manufacturing cost will be relatively high. In addition, the existing optical module pull ring unlocking sheet metal is basically exposed, and a limiting structure cannot be designed on the outside. This makes it easy for the pull ring sheet metal unlocking parts to be squeezed and deformed or scratched during circulation, which may affect product quality and cause customer complaints.

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-8 The present invention provides an optical module, comprising: an upper cover 100 and a base 200, which are spliced together and have mounting grooves 101 symmetrically distributed on both sides, and a first notch 101a and a second notch 101b are respectively provided at both ends of the mounting groove 101; The cage 300 has a tongue 301 thereon, and the cage 300 is plugged into and matched with the assembled upper cover 100 and base 200; The unlocking link 400 is disposed in the space formed by the joint of the mounting groove 101 on the upper cover 100 and the base 200 after splicing. The two ends of the unlocking link 400 extend to the first notch 101a and the second notch 101b respectively. The unlocking link 400 includes a rotating portion 401; When one end of the unlocking link 400 is pressed, the unlocking link 400 rotates around the rotating portion 401 so that the other end pushes the tongue 301 to move and unlock the device.

[0019] This embodiment uses a push-type unlocking method, combined with a labor-saving unlocking link 400, which changes according to the size of the applied force. The height can be adjusted to adapt to the assembly differences caused by the dimensional tolerance chain of multiple components, solving the problem of dimensional chain matching of conventional straight-pull and rotary pull rings and unlocking parts, avoiding the risk of unlocking failure, and improving unlocking stability.

[0020] The core component unlocking link 400 of the present invention can also be made by various production processes and materials such as die casting, injection molding, and extrusion, which can provide more and better choices during product development and design, and can ensure stable and reliable product quality and reduce costs and increase efficiency.

[0021] In one embodiment, the mounting groove 101 includes an axis groove 101 c located between the first notch 101 a and the second notch 101 b , and the rotating portion 401 is rotatably engaged with the axis groove 101 c .

[0022] This embodiment is configured such that the shaft groove 101c is integrally formed on the upper cover 100 and the base 200, and the structure of the upper cover 100 and the base 200 body is directly utilized, which can reduce the difficulty of processing and assembly, so that after the unlocking link 400 is installed, it can rotate around the rotating part 401, and then press one end of the unlocking link 400 to drive the other end to push the tongue 301 to complete the optical module unlocking function.

[0023] It should be noted that the cooperation between the rotating part 401 and the shaft groove 101c is only a preferred embodiment. The unlocking link 400 can also be realized by passing a rotating shaft through it or other methods of making the unlocking link 400 rotate around the fulcrum are all within the scope of protection of this application.

[0024] In one embodiment, the unlocking link 400 also includes a straight rod 402 and an oblique rod 403 connected together at one end. Specifically, the rotating portion 401 is provided at the connection between the straight rod 402 and the oblique rod 403, and the rotating portion 401 is integrally formed with the straight rod 402 and the oblique rod 403; the other end of the straight rod 402 is provided with a first protrusion 404, and the first protrusion 404 is connected to an unlocking key 405, and the other end of the oblique rod 403 is provided with an unlocking boss 406.

[0025] This embodiment is configured such that when unlocking, the unlocking button 405 is pressed, the straight rod 402 and the inclined rod 403 rotate around the rotating part 401, and the unlocking boss 406 presses against the tongue 301 and pushes it, thereby realizing the unlocking function.

[0026] In one embodiment, the inclined rod 403 has a slide 407 connected to the unlocking boss 406 , and the slide 407 is in an inclined shape.

[0027] This embodiment is configured in such a way that, through the configuration of the slide 407, when the tolerance chain of the matching dimensions of multiple components is large, the protrusion can be brought into contact with the slide 407 when the unlocking stroke is large. Since the unlocking link 400 is in a rotating state during the unlocking process, the inclined surface of the slide 407 can better adapt to the movement of the unlocking link 400, making the unlocking process smoother and with less resistance.

[0028] In one embodiment, the straight rod 402 is provided with a second protrusion 408 disposed opposite to the first protrusion 404. An elastic member 409 is provided on the path of the second protrusion 408 when the optical module is unlocked. Specifically, the elastic member 409 can be a spring.

[0029] This embodiment is configured such that, through the provision of the elastic member 409, during the unlocking process of the unlocking link 400, the second protrusion 408 contacts and compresses the elastic member 409. After the unlocking is completed, the unlocking key 405 is released, so that the unlocking link 400 is quickly reset under the action of the elastic member 409, facilitating the subsequent unlocking operation. At the same time, the provision of the elastic member 409 can improve the operator's linear operation feel during the unlocking process, improve the unlocking accuracy, and avoid the problem of unlocking difficulty or failure due to the difficulty in controlling the applied force.

[0030] In one embodiment, the length ratio of the straight rods 402 to the oblique rods 403 is 2:1.

[0031] This embodiment is configured to reduce the difficulty of operation during the unlocking process as much as possible while taking into account the unlocking function. That is, only a small force needs to be applied during unlocking, and the unlocking function can be easily achieved through the leverage effect.

[0032] In one embodiment, see Figure 9 The inner surface of the shaft groove 101c has a built-in groove 101d, and the rotating part 401 has an elastic protrusion 4011. When the unlocking link 400 is installed, the elastic protrusion 4011 slides from the shaft groove 101c into the built-in groove 101d, wherein the elastic protrusion 4011 is in a compressed state when contacting the inner surface of the shaft groove 101c, and is in a completely released state when contacting the built-in groove 101d.

[0033] This embodiment is configured such that when installing the unlocking link 400, the unlocking link 400 is aligned with the installation groove 101 and pressed in. During the pressing-in process, the elastic protrusion 4011 contacts the inner wall of the shaft groove 101c and is in a compressed state. When the unlocking link 400 is installed, the elastic protrusion 4011 slides into the built-in groove 101d and is in an unstressed state. At this time, in the subsequent unlocking process, as the unlocking link 400 rotates, the elastic protrusion 4011 moves in the built-in groove 101d to limit it, thereby avoiding the problem of deviation between the rotating part 401 and the shaft groove 101c after repeated unlocking, resulting in difficulty or failure in unlocking.

[0034] In one embodiment, the elastic protrusion 4011 is spherical and can rotate freely about its center. A stopper 101d1 is provided at the end of the internal groove 101d. Specifically, the rotating portion 401 has a groove for mounting the elastic protrusion 4011. The elastic protrusion 4011 is embedded in a support block, which slides in the groove. A spring connected to the support block is also provided within the groove.

[0035] This embodiment is configured such that the elastic protrusion 4011 is configured to be a spherical structure that can rotate freely around its center, so that during the unlocking process, as the unlocking link 400 rotates, the elastic protrusion 4011 rolls in the built-in groove 101d, thereby reducing the friction between the rotating part 401 and the shaft groove 101c, and reducing the consumption between the rotating part 401 and the shaft groove 101c, thereby improving the service life of the unlocking link 400.

[0036] In one embodiment, see Figure 10 The unlocking button 405 is provided on one side of the base 200 and is connected to a pressure rod 4051 extending to the opposite side. The end of the pressure rod 4051 abuts against one end of a rocker plate 4052, and the other end of the rocker plate 4052 abuts against the unlocking link 400 provided on the same side. Specifically, the pressure rod 4051 passes through the second protrusion 408 and extends to the other side opposite the unlocking button 405. The rocker plate 4052 is provided with a rotation fulcrum.

[0037] This embodiment is configured such that, when unlocking, it is only necessary to press the unlock button 405 provided on one side, and the unlock button 405 presses the end of the unlock link 400 on the same side, and simultaneously pushes the pressure rod 4051 to move, so that the end of the pressure rod 4051 pushes the rocker 4052 to move, and the end of the rocker 4052 pushes the end of the unlock link 400 on the other side, thereby realizing the unlocking of the optical module by pressing the unlock button 405 on one side, so that the unlocking function can adapt to operation in a narrow space, thereby improving the adaptability of the unlocking function in various environments.

[0038] In one embodiment, when the optical module is in the locked state, the second protrusion 408 is spaced apart from the elastic member 409. Specifically, when the optical module is in the locked state, the distance between the second protrusion 408 and the elastic member 409 is the minimum travel required for the unlocking link 400 to move when the optical module is unlocked.

[0039] This embodiment is configured such that, when unlocking, the operator can easily drive the unlocking link 400 to the nearest position required to unlock the optical module. During the process, the operator will not be subject to resistance from the elastic member 409 and can drive the unlocking link 400 into place more quickly. Subsequently, according to the assembly differences caused by the tolerance chain of the matching dimensions of multiple components, the unlocking key 405 is pressed again in a timely manner. At this time, the second protrusion 408 compresses the elastic member 409 until the unlocking function is completed, so that the operator can be given two hand feedbacks during the unlocking process, and there is no need to maintain the position of the unlocking link 400 throughout the process, which reduces the difficulty of unlocking and improves the unlocking efficiency.

[0040] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or suggesting their 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 at least one of such features. In addition, the meaning of "and / or" appearing throughout the text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or schemes in which A and B are satisfied at the same time. In addition, "multiple" refers to more than two.
