Description

Technical Field

[0001] This utility model belongs to the field of optical modules, and specifically relates to an optical module housing. Background Technology

[0002] Optical modules are key devices in fiber optic communication, performing photoelectric and electro-optic conversion, and typically work in conjunction with switches. Optical modules generally have a pull ring, which is compatible with the locking / unlocking mechanism in the switch. By operating the pull ring, the optical module can be locked / unlocked from the switch.

[0003] Currently, optical module housings generally consist of a base and a top cover. The optical engine is installed inside the base (the specific type of optical engine depends on the type of optical module housing). A pull ring is installed at the connection between the base and the top cover. Spring holes are provided on both sides of the optical module housing to install compression springs. The compression springs act on the pull rings, using them to reset the pull rings. The current assembly structure of the optical module housing and pull ring has the following problems: 1) Insufficient limiting of the pull ring and compression spring, making them prone to misalignment during use, affecting long-term stability; 2) The assembly of the base, top cover, compression spring, and pull ring is relatively complex and time-consuming. Utility Model Content

[0004] The purpose of this invention is to provide an optical module housing that can be used stably for a long time and is easy to assemble.

[0005] The technical solution adopted in this utility model is: An optical module housing includes a base, a pull ring, and a top cover. The base has a positioning post, which is fitted with a torsion spring. The torsion spring has three force points: the middle force point is fitted onto the positioning post, and the two outer force points are extension arms extending in opposite directions on the same side. The pull ring includes a pair of unlocking tabs. The two unlocking tabs are connected at one end by a handle, at the other end by unlocking parts, and connected in the middle by a connecting part. The two unlocking tabs are slidably mounted on both sides of the base via a guide structure. The handle is used to pull the unlocking tabs outwards, and the unlocking parts are used to trigger unlocking when sliding outwards. The connecting part has a torsion spring stop plate, which extends into the base and abuts against the two extension arms. When the unlocking tab slides outwards, it causes the torsion spring stop plate to press against the extension arms. When the unlocking tab is released, the torsion spring causes the unlocking tab to return to its original position via the extension arms and the torsion spring stop plate. The top cover is mounted on the base.

[0006] Preferably, the extension arm includes a force-receiving section and a force-transmitting section, the torsion spring baffle abuts against the force-receiving section in line contact, the force-receiving section is connected to the torsion spring body through the force-transmitting section, and the force-transmitting sections of the two extension arms are arranged in a V-shape.

[0007] Preferably, the guide structure includes a side slide groove on the side of the unlocking slide and a side guide block on the side of the base, with the side guide block slidably engaged in the side slide groove.

[0008] Preferably, the guide structure further includes a bottom guide block located at the bottom of the unlocking slide and a bottom slide groove located at the bottom of the side of the base, with the bottom guide block slidably fitted within the bottom slide groove.

[0009] Preferably, the base is provided with a torsion spring baffle groove, and the torsion spring baffle extends into the base through the torsion spring baffle groove.

[0010] Preferably, after the top cover is installed on the base, the base works together to axially limit the torsion spring at the middle force point on the positioning post.

[0011] Preferably, the torsion spring baffle is formed by punching and bending directly on the connecting part, with the root of the torsion spring baffle connected to the connecting part and the remaining part separated from the connecting part by punching.

[0012] Preferably, the top cover and the base are connected by screws, and the top cover and the base are provided with corresponding threaded holes.

[0013] Preferably, the base is provided with mounting components for mounting the light engine.

[0014] Preferably, the unlocking part is an outwardly protruding structure.

[0015] The beneficial effects of this utility model are: The pull ring slides with the two sides of the base through the unlocking sliders on both sides. The torsion spring is sleeved on the positioning post and then held in place by the torsion spring stop plate to complete the positioning of position and direction. Both have sufficient limits and will not deviate, so it can be used stably for a long time. First, put the torsion spring on the positioning post, then install the pull ring on the base, and finally install the top cover on the base. The pull ring can be pre-assembled, and the key is that the assembly is convenient. Attached Figure Description

[0021] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0022] This embodiment discloses an optical module housing, such as Figures 1 to 4 As shown, it includes a base 300, a pull ring 100, and a top cover 200; wherein: the base 300 is provided with a vertical positioning post 303, the positioning post 303 is fitted with a torsion spring 310, the torsion spring 310 has three force points, the middle force point is sleeved on the positioning post 303, and the two side force points are extension arms 311 extending in opposite directions on the same side, see Figure 3 and Figure 4 The pull ring 100 includes a pair of unlocking slides 120. The two unlocking slides 120 are connected at one end by a handle 110, and at the other end by unlocking parts 122 respectively. They are connected in the middle by a connecting part 125. The two unlocking slides 120 are slidably mounted on both sides of the base 300 via a guide structure. The handle 110 is used to pull the unlocking slides 120 outwards. The unlocking parts 122 are used to trigger unlocking when sliding outwards. The connecting part 125 is provided with a torsion spring stop 123. The torsion spring stop 123 extends into the base 300 and abuts against the two extension arms 311 respectively. When the unlocking slides 120 slide outwards, the torsion spring stop 123 presses against the extension arms 311. When the unlocking slides 120 are released, the torsion spring 310 will drive the unlocking slides 120 to reset via the extension arms 311 and the torsion spring stop 123. Figures 1 to 4 The top cover 200 is mounted on the base 300, see... Figure 1 and Figure 2 .

[0023] The pull ring 100 slides with the two sides of the base 300 through the unlocking slides 120 on both sides. The torsion spring 310 is sleeved on the positioning post 303 and then held in place by the torsion spring stop 123 to complete the positioning of position and direction. Both have sufficient limit and will not deviate, and can be used stably for a long time. First, the torsion spring 310 is sleeved on the positioning post 303, then the pull ring 100 is installed on the base 300, and finally the top cover 200 is installed on the base 300. The pull ring 100 can be pre-assembled, and the key is that the assembly is convenient.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, preferably, the guide structure includes a side sliding groove 121 on the side of the unlocking slide 120, a side guide block 305 on the side of the base 300, a bottom guide block 124 at the bottom of the unlocking slide 120, and a bottom sliding groove 306 at the bottom of the side of the base 300. The side guide block 305 is slidably engaged in the side sliding groove 121, and the bottom guide block 124 is slidably engaged in the bottom sliding groove 306.

The root of the torsion spring baffle 123 is connected to the connecting part 125, and the remaining part is separated from the connecting part 125 by punching, which is convenient to manufacture.

[0026] like Figure 2 and Figure 4 As shown, in this embodiment, preferably, the upper cover 200 and the base 300 are connected by screws 320, and the upper cover 200 and the base 300 are provided with corresponding threaded holes 304.

[0027] like Figure 3 As shown, in this embodiment, preferably, the extension arm 311 includes a force-receiving section 311a and a force-transmitting section 311b. The torsion spring baffle 123 abuts against the force-receiving section 311a in line contact. The force-receiving section 311a is connected to the torsion spring 310 body through the force-transmitting section 311b. The force-transmitting sections 311b of the two extension arms 311 are arranged in a V-shape. This arrangement allows the torsion spring baffle 123 to stably abut against the extension arm 311 to limit the angle of the torsion spring 310, and also effectively transmits the restoring force of the torsion spring 310.

[0028] like Figure 3 As shown, in this embodiment, preferably, the base 300 is provided with a torsion spring baffle groove 302, and the torsion spring baffle 123 extends into the base 300 through the torsion spring baffle groove 302.

[0029] like Figure 4 As shown, in this embodiment, the base 300 is provided with a mounting member 301 for mounting the optical engine, and the unlocking part 122 is an outwardly protruding protrusion structure (adapted to the locking / unlocking mechanism in the switch).

[0030] In this embodiment, preferably, after the upper cover 200 is installed on the base 300, the base 300 works with the torsion spring 310 to axially limit the middle force point on the positioning post 303, so as to prevent the torsion spring 310 from coming out of the positioning post 303.
