The elastic piece 122 may be made of metal material, and in some embodiments of the present disclosure, it may be made of sheet metal material that is convenient for processing and shaping. The stop wall is used to prevent the movement of the object. For example, when an object that can move in a single direction touches the stop wall, it is blocked by the stop wall and stops moving.

悬梁13，桥接在两个悬臂之间，用于连接两个悬臂12，悬梁13至少部分覆盖于第一凹陷部的顶端可以保证安装在第一凹陷部内的弹性件206不易滑落，同时也可以降低弹性件处于压缩状态时被弹出的风险。悬梁的上表面设置有通孔131，通孔位131的孔径大于弹性件206的宽度，以使得弹性件可以穿过通孔131。在一可行性实施例中可以在悬梁13的侧壁上设置卡勾让位部132，卡勾让位部132在水平方向上的深度大于卡勾的厚度，将卡勾14设置于卡勾让位部132内可以对卡勾14起到保护作用，防止卡勾14磨损。悬梁13的材质可以采用金属材质，在本公开的某些实施例中可以采用便于加工成型的钣金材质。The cantilever beam 13 is bridged between the two cantilever arms and is used to connect the two cantilever arms 12. The cantilever beam 13 at least partially covers the top end of the first recessed portion to ensure that the elastic member 206 installed in the first recessed portion is not easy to slip off, and can also be lowered There is a risk that the elastic member will be ejected when it is in a compressed state. The upper surface of the cantilever beam is provided with a through hole 131, and the aperture of the through hole 131 is larger than the width of the elastic member 206 so that the elastic member can pass through the through hole 131. In a feasible embodiment, a hook giving way portion 132 may be provided on the side wall of the suspension beam 13, and the depth of the hook giving way portion 132 in the horizontal direction is greater than the thickness of the hook.

下面将结合附图，详细说明本公开实施例的光模块的装配过程作以说明，具体的可以参阅图18～图20。The assembly process of the optical module of the embodiment of the present disclosure will be described in detail below in conjunction with the accompanying drawings. For details, please refer to FIGS. 18-20.

步骤一：将上壳体201倾斜放置，上壳体201的第一壳体21在垂直方向上的高度高于上壳体201的第二壳体22在垂直方向上的高度，此时弹性件206的一端与第一凹陷部221的内壁限位接触。然后将上壳体放平。此时，上壳体201与弹性件206形成的装配体可以参阅图18，图18为一可行性实施例提供的上壳体201与弹性件206形成的装配体的示意图。Step 1: Place the upper housing 201 at an angle. The height of the first housing 21 of the upper housing 201 in the vertical direction is higher than the height of the second housing 22 of the upper housing 201 in the vertical direction. One end of the 206 is in positional contact with the inner wall of the first recess 221. Then lay the upper case flat. At this time, the assembly formed by the upper housing 201 and the elastic member 206 can be referred to FIG. 18, which is a schematic diagram of the assembly formed by the upper housing 201 and the elastic member 206 according to a feasible embodiment.

步骤二：调整解锁部件203的位置，使得解锁部件203的卡勾14位于上壳体201的第一凹陷部221的正上方，具体的可以参阅图19。图19为本公开实施例提供的装配时上壳体201与解锁部件203形成的装配结构的剖视图。此时，上壳体201的第二壳体22位于解锁部件203的悬梁13的下方，解锁部件203的卡勾14位于上壳体201的第一凹陷部221的正上方。Step 2: Adjust the position of the unlocking component 203 so that the hook 14 of the unlocking component 203 is located directly above the first recess 221 of the upper housing 201. For details, refer to FIG. 19. FIG. 19 is a cross-sectional view of the assembly structure formed by the upper housing 201 and the unlocking component 203 during assembly according to an embodiment of the disclosure. At this time, the second housing 22 of the upper housing 201 is located below the suspension beam 13 of the unlocking member 203, and the hook 14 of the unlocking member 203 is located directly above the first recess 221 of the upper housing 201.

步骤三：将解锁部件203自上而下与上壳体201扣合，此时，解锁部件203的悬梁13位于第一凹陷部221的上表面，同时解锁部件203的卡勾14伸入上壳体201的第一凹陷部221内，具体的结构可以参阅图20和图21。图20为本公开实施例提供的装配时上壳体201与解锁部件203形成装配结构的示意图；图21为图20示出的装配体的剖视图。从图21中可以看出，此时弹性件206的固定端与第一凹陷部221的内壁限位接触，弹性件206的移动端与卡勾14接触。Step 3: Fasten the unlocking component 203 with the upper casing 201 from top to bottom. At this time, the cantilever 13 of the unlocking component 203 is located on the upper surface of the first recess 221, and the hook 14 of the unlocking component 203 extends into the upper casing. In the first recess 221 of the body 201, the specific structure can refer to FIG. 20 and FIG. 21. 20 is a schematic diagram of an assembly structure formed by the upper housing 201 and the unlocking member 203 during assembly provided by an embodiment of the disclosure; FIG. 21 is a cross-sectional view of the assembly shown in FIG. 20. It can be seen from FIG. 21 that, at this time, the fixed end of the elastic member 206 is in contact with the inner wall of the first recess 221 in a limit position, and the moving end of the elastic member 206 is in contact with the hook 14.

至此完成装配。This completes the assembly.

下面将结合附图，详细说明本公开实施例提供的光模块的复位过程作以说明。Hereinafter, the reset process of the optical module provided by the embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

当将光模块插入交换机时，交换机笼内的卡片位于弯折件的上表面，并与第三凹陷部211的止位壁211a卡接，进而实现光模块在笼内的锁紧，此时光模块处于锁紧状态。当光模块从交换机笼内拔出断开时，向弹性件压缩方向拉动手柄11，手柄11带动悬臂12、弯折121、弹片122向压缩弹性件的方向移动，由于弹片122的凸起部122a向外凸起，在移动的过程中凸起部122a挤压交换机的卡片，使得交换机的卡片与第三凹陷部211脱离。此时上壳体201与解锁部件203形成装配结构可以参阅图22。释放拉动手柄11的拉力，弹性件206将弹性势能转换为动能，进而对解锁部件施加一个作用力，解锁部件在这个力的作用下，向弹性件206伸展的方向移动，进而实现解锁部件203的复位，此时，上壳体201与解锁部件203形成装配结构可以参阅图20。When the optical module is inserted into the switch, the card in the switch cage is located on the upper surface of the bending piece, and is snapped with the stop wall 211a of the third recess 211, so as to realize the locking of the optical module in the cage. At this time, the optical module In a locked state. When the optical module is pulled out and disconnected from the switch cage, pull the handle 11 toward the compression direction of the elastic member. The handle 11 drives the cantilever 12, the bend 121, and the elastic piece 122 to move in the direction of compressing the elastic piece, due to the protrusion 122a of the elastic piece 122 Protruding outward, the raised portion 122a squeezes the card of the switch during the movement, so that the card of the switch is separated from the third recessed portion 211. At this time, the upper housing 201 and the unlocking component 203 form an assembly structure, which can be seen in FIG. 22. Releasing the pulling force of pulling the handle 11, the elastic member 206 converts the elastic potential energy into kinetic energy, and then applies a force to the unlocking member. Under the action of this force, the unlocking member moves in the direction in which the elastic member 206 extends, thereby realizing the unlocking member 203. Reset, at this time, the upper housing 201 and the unlocking component 203 form an assembly structure, which can be referred to FIG. 20.

本公开实施例示出的光模块包括上壳体和下壳体。其中，上壳体和下壳体形成的腔体，在腔体内设置有用于承载及连接光电器件的电路板。上壳体的侧壁上设置有用于与交换机相互锁紧的解锁部件。上壳体的上表面设置有第一凹陷部。弹性件位于第一凹陷部内，其固定端与第一凹陷部的内壁限位接触，其移动端与解锁部件接触，以实现解锁时弹性件将弹性势能转换为动能，驱动解锁部件复位。本公开实施例示出的解锁部件包括两个悬臂，分别与上壳体的侧壁贴合进而实现锁紧部件与上壳体的可移动式连接。锁紧部件还包括用于连接两个悬臂的悬梁，悬梁至少部分覆盖在弹性件的上方。锁紧部件还包括卡勾，卡勾的连接端设置在悬梁的侧壁上，卡勾的自由端向下弯曲以实现自由端可以伸入第一凹陷部。可见本公开实施例提供的光模块，由于悬梁覆盖弹性件的长度是固定的，当卡勾带动弹性件移动时弹性件逐渐被压缩，相应的弹性件的长度逐渐减小，弹性件未被覆盖的长度逐渐缩短，进而可以降低弹性件压缩过程中被弹出的风险。The optical module shown in the embodiment of the present disclosure includes an upper housing and a lower housing. Wherein, the cavity formed by the upper shell and the lower shell is provided with a circuit board for carrying and connecting optoelectronic devices in the cavity. The side wall of the upper shell is provided with an unlocking component for mutual locking with the switch. The upper surface of the upper casing is provided with a first recess. The elastic member is located in the first recessed portion, its fixed end is in contact with the inner wall of the first recessed portion in a limit contact, and its moving end is in contact with the unlocking member, so that the elastic member converts the elastic potential energy into kinetic energy when unlocking, and drives the unlocking member to reset. The unlocking component shown in the embodiment of the present disclosure includes two cantilevers which are respectively attached to the side wall of the upper housing to realize the movable connection between the locking component and the upper housing. The locking component further includes a cantilever beam for connecting the two cantilever arms, and the cantilever beam at least partially covers the elastic member. The locking component further includes a hook, and the connecting end of the hook is arranged on the side wall of the suspension beam, and the free end of the hook is bent downward to realize that the free end can extend into the first recessed portion. It can be seen that in the optical module provided by the embodiments of the present disclosure, since the length of the cantilever beam covering the elastic member is fixed, the elastic member is gradually compressed when the hook drives the elastic member to move, and the length of the corresponding elastic member is gradually reduced, and the elastic member is not covered. The length of the elastic member is gradually shortened, thereby reducing the risk of the elastic member being ejected during the compression process.
