Description

Technical Field

[0001] This application relates to the field of optical communication technologies, and particularly to an electrical port module. Background Art

[0002] An electrical port module, also known as an optical port to electrical port module, is an optoelectronic conversion module and a frequently used module type in optical communication. It is used to transmit electrical signals and has a wide range of applications. For example, on an optical network terminal, it is used to connect a network cable to a host device such as an optical network terminal.

[0003] An electrical port module usually includes an unlocking component. The unlocking component can make the electrical port module be caught by an inner bayonet in the cage when inserted into the cage of the host computer to prevent it from loosening and falling out, realizing the clamping connection between the electrical port module and the host computer. The unlocking component can also release the clamping connection between the electrical port module and the host computer, enabling the electrical port module to be easily pulled out of the cage. Summary of the Invention

[0004] This application provides an electrical port module, which realizes or releases the connection relationship between the electrical port module and the host computer through a self - contained unlocking component.

[0005] The electrical port module provided by this application includes:

[0006] An upper shell with a clamping component on its surface;

[0007] An unlocking handle is arranged at the end of the upper shell. One end of the unlocking handle is rotatably connected to the upper shell. On both sides of the end of the unlocking handle connected to the upper shell, a notch and a groove are respectively formed. The notch and the groove rotate with the rotation of the unlocking handle;

[0008] An unlocker is slidably connected to the upper shell. The unlocker includes a body structure. On the end face of the body structure facing the unlocking handle, a first arm and a second arm respectively extend. A bent portion is formed at the end of the second arm. The first arm is arranged in the notch. The length of the first arm is less than the length of the second arm. Wherein, with the rotation of the notch, the first arm slides along the inner wall of the notch to disengage from the notch, and then abuts against the side wall connected to the notch, so that the first arm drives the body structure to move towards the clamping component. With the movement of the first arm, the bent portion enters the groove. During the rotation of the groove, the inner wall of the groove presses the bent portion, so that the second arm drives the body structure to move towards the clamping component.

[0009] In the electrical interface module provided by this application, it includes an upper housing, an unlocking handle, and an unlocker. The surface of the upper housing has a engaging component, which is engaged and connected with the elastic piece of the host computer through the engaging component, so as to engage the electrical interface module in the host computer. The unlocking handle is arranged at the end of the upper housing, and one end of the unlocking handle is rotatably connected to the upper housing. Notches and grooves are respectively formed on both sides of the end of the unlocking handle connected to the upper housing, and both the notch and the groove rotate as the unlocking handle rotates. The unlocker is slidably connected to the upper housing. The unlocker includes a body structure. First and second arms respectively extend from the end face of the body structure facing the unlocking handle, and a bending portion is formed at the end of the second arm. The first arm is arranged in the notch. When the unlocking handle is rotated, the notch rotates accordingly. The first arm is squeezed by the inner wall of the notch at the beginning of the rotation of the notch, so that the first arm slides along the inner wall of the notch until it slips out of the notch, and then continues to be abutted by the side wall connected to the notch, so that the first arm drives the body structure to move towards the engaging component. When the electrical interface module is in the locked state, the first arm is arranged in the notch. In order to avoid the unlocker acting on the elastic piece and the engaging component at this time, the length of the first arm is short, so that the unlocker is as far away from the elastic piece and the engaging component as possible in the current state, so as to maintain the current locked state. When the length of the first arm is short, during the movement process, the connection between the first arm and the notch is disconnected due to misalignment, and until the connection between the first arm and the abutting side wall is also disconnected due to misalignment, resulting in the first arm no longer being squeezed and no longer generating an unlocking stroke. Therefore, as the first arm moves, the bending portion of the second arm enters the groove. During the rotation of the groove, the inner wall of the groove squeezes the bending portion, so that the second arm drives the body structure to move towards the engaging component, and continues to generate an unlocking stroke until the elastic piece is lifted, so that the engaging component is separated from the elastic piece, thereby releasing the engaging connection between the electrical interface module and the host computer. In this application, exemplarily, before the first arm slips out of the notch, the second arm is squeezed by the groove, so that after the first arm is disconnected from the notch, the second arm continues to drive the body structure to move, thereby generating a longer unlocking stroke. In this application, the first arm and the second arm are respectively stressed, so as to drive the body structure to move respectively, providing a continuous and sufficient unlocking stroke to completely separate the electrical interface module from the host computer and realize the unlocking of the electrical interface module.

[0035] In an optical communication system, an optical signal is used to carry information to be transmitted, and the optical signal carrying the information is transmitted to an information processing device such as a computer through an information transmission device such as an optical fiber or an optical waveguide to complete the information transmission. Since light has a passive transmission characteristic when transmitted through an optical fiber or an optical waveguide, low-cost and low-loss information transmission can be achieved. In addition, the signal transmitted by an information transmission device such as an optical fiber or an optical waveguide is an optical signal, while the signal that an information processing device such as a computer can recognize and process is an electrical signal. Therefore, in order to establish an information connection between an information transmission device such as an optical fiber or an optical waveguide and an information processing device such as a computer, it is necessary to realize the mutual conversion between electrical signals and optical signals.

[0036] The electrical port module realizes the above-mentioned function of mutual conversion between optical signals and electrical signals in the field of optical communication technology. The electrical port module includes an optical port and an electrical port. The electrical port module realizes optical communication with information transmission devices such as optical fibers or optical waveguides through the optical port, and realizes electrical connection with an optical network terminal (for example, an optical modem) through the electrical port. The electrical connection is mainly used for power supply, I2C signal transmission, data information transmission, grounding, etc.; the optical network terminal transmits electrical signals to information processing devices such as computers through a network cable or Wi-Fi technology.

[0037] Figure 1 It is a connection relationship diagram of an optical communication system according to some embodiments. As Figure 1 shown, the optical communication system includes a remote server 1000, a local information processing device 2000, an optical network terminal 100, an optical module 200, an optical fiber 101, and a network cable 103.

[0038] One end of the optical fiber 101 is connected to the remote server 1000, and the other end is connected to the optical network terminal 100 through the optical module 200. The optical fiber itself can support long-distance signal transmission, such as signal transmission over several kilometers (6 kilometers to 8 kilometers). On this basis, if a repeater is used, theoretically infinite-distance transmission can be achieved. Therefore, in a general optical communication system, the distance between the remote server 1000 and the optical network terminal 100 can usually reach several kilometers, dozens of kilometers, or hundreds of kilometers.

[0039] One end of the network cable 103 is connected to the local information processing device 2000, and the other end is connected to the optical network terminal 100. The local information processing device 2000 can be any one or several of the following devices: router, switch, computer, mobile phone, tablet computer, television, etc.

[0040] The physical distance between the remote server 1000 and the optical network terminal 100 is greater than the physical distance between the local information processing device 2000 and the optical network terminal 100. The connection between the local information processing device 2000 and the remote server 1000 is completed by the optical fiber 101 and the network cable 103; the connection between the optical fiber 101 and the network cable 103 is completed by the optical module 200 and the optical network terminal 100.

[0041] The optical module 200 includes an optical port and an electrical port. The optical port is configured to be connected to the optical fiber 101, so that the optical module 200 establishes a bidirectional optical signal connection with the optical fiber 101; the electrical port is configured to be connected to the optical network terminal 100, so that the optical module 200 establishes a bidirectional electrical signal connection with the optical network terminal 100. The optical module 200 realizes the mutual conversion between optical signals and electrical signals, so that an information connection is established between the optical fiber 101 and the optical network terminal 100. For example, the optical signal from the optical fiber 101 is converted into an electrical signal by the optical module 200 and then input into the optical network terminal 100, and the electrical signal from the optical network terminal 100 is converted into an optical signal by the optical module 200 and input into the optical fiber 101. Since the optical module 200 is a tool for realizing the mutual conversion between optical signals and electrical signals and does not have the function of processing data, the information does not change in the above-mentioned photoelectric conversion process.

[0042] The optical network terminal 100 includes a housing that is roughly in the shape of a rectangular parallelepiped, and an optical port module interface 102 and a network cable interface 104 arranged on the housing. The optical port module interface 102 is configured to access the optical module 200, so that the optical network terminal 100 establishes a bidirectional electrical signal connection with the optical module 200; the network cable interface 104 is configured to access the network cable 103, so that the optical network terminal 100 establishes a bidirectional electrical signal connection with the network cable 103. The optical module 200 and the network cable 103 are connected through the optical network terminal 100. For example, the optical network terminal 100 transmits the electrical signal from the optical module 200 to the network cable 103, and transmits the electrical signal from the network cable 103 to the optical module 200. Therefore, the optical network terminal 100, as the host computer of the optical module 200, can monitor the operation of the optical module 200. In addition to the optical network terminal 100, the host computer of the optical module 200 can also include an optical line terminal (Optical Line Terminal, OLT) and the like.

[0043] The remote server 1000 establishes a bidirectional signal transmission channel with the local information processing device 2000 through the optical fiber 101 , the optical module 200 , the optical network terminal 100 and the network cable 103 .

[0044] To facilitate access to the network cable 103, the network cable interface 104 of the optical network terminal 100 includes an electrical port module, on which a network port terminal is provided, and the network port terminal is connected through a connector of the network cable 103. In the embodiment of the present application, the electrical port module is not only used for the optical network terminal 100, but also for host devices such as routers and switches.

[0045] Figure 2 FIG. 1 is a partial structural diagram of an optical network terminal according to some embodiments. Figure 2As shown, the optical network terminal 100 further includes a PCB circuit board 105 disposed inside the housing, a cage 106 disposed on the surface of the PCB circuit board 105, a radiator 107 disposed on the cage 106, and an electrical connector disposed inside the cage 106. The electrical connector is configured to access the electrical port of the electrical port module; the radiator 107 has raised structures such as fins to increase the heat dissipation area.

[0046] The electrical port module is inserted into the cage 106 of the optical network terminal 100, and the cage 106 fixes the electrical port module. The heat generated by the electrical port module is conducted to the cage 106 and then dissipated through the radiator 107. After the electrical port module is inserted into the cage 106, the electrical port of the electrical port module is connected to the electrical connector inside the cage 106, thereby establishing a two-way electrical signal connection between the electrical port module and the optical network terminal 100. In addition, the optical port of the electrical port module is connected to the optical fiber 101, thereby establishing a two-way optical signal connection between the electrical port module and the optical fiber 101.

[0047] Figure 3 FIG. is a structural diagram of an electrical port module according to some embodiments; Figure 4 FIG. is an exploded view of an electrical port module according to some embodiments. As Figure 3 and Figure 4 shown, the electrical port module 300 includes a shell, a circuit board disposed inside the shell, and devices electrically connected to the circuit board.

[0048] The shell includes an upper shell 310 and a lower shell 320. The upper shell 310 covers the lower shell 320 to form the above shell with two openings; the outer contour of the shell generally presents a rectangular body. Exemplarily, the two openings include openings 330 and 340.

[0049] The direction of the line connecting the two openings 340 and 350 may be consistent with the length direction of the electrical port module 300 or may not be consistent with the length direction of the electrical port module 300. For example, the opening 340 is located at the end of the electrical port module 300 ( Figure 3 the right end), and the opening 350 is also located at the end of the electrical port module 300 ( Figure 3 the left end). Alternatively, the opening 340 is located at the end of the electrical port module 300, while the opening 350 is located at the side of the electrical port module 300. The opening 340 is the electrical port, and the gold fingers of the circuit board extend from the electrical port and are inserted into the host computer (for example, the optical network terminal 100); the opening 350 is the optical port and is configured to access the external network cable 103 so that the network cable 103 is connected to the network port terminal inside the electrical port module 300.

[0050] Adopting the assembly method of combining the upper housing 310 and the lower housing 320 facilitates the installation of devices such as circuit boards into the housing, and the upper housing 310 and the lower housing 320 form a package protection for these devices. In addition, when assembling devices such as circuit boards, it is convenient for the deployment of the positioning components, heat dissipation components, and electromagnetic shielding components of these devices, which is conducive to the implementation of automated production.

[0051] In some embodiments, the upper housing 310 and the lower housing 320 are generally made of metal materials, which is conducive to achieving electromagnetic shielding and heat dissipation.

[0052] In some embodiments, the electrical port module 300 further includes an unlocking component 400 located outside its housing. The unlocking component 400 is configured to achieve a fixed connection between the electrical port module 300 and the host computer, or to release the fixed connection between the electrical port module 300 and the host computer.

[0053] Exemplarily, the unlocking component 400 is located on the outer wall of the electrical port module 300 and has a engaging component that matches the host computer cage (for example, the cage 106 of the optical network terminal 100). When the electrical port module 300 is inserted into the cage of the host computer, the engaging component of the electrical port module 300 fixes the electrical port module 300 in the cage of the host computer; when the unlocking component 400 is pulled, the engaging relationship between the electrical port module 300 and the host computer can be released, so that the electrical port module 300 can be withdrawn from the cage of the host computer.

[0054] In some embodiments, the unlocking component 400 includes an unlocking handle 410 and an unlocker 420. In the present application, the unlocking handle 410 is rotatably connected to the upper housing 310, and the unlocker 420 is slidably connected to the upper housing 310. When it is necessary to unlock the electrical port module 300, when the unlocking handle 410 is pulled, the unlocker 420 can be driven to slide along the upper housing 310. Through the sliding of the unlocker 420, the engaging component of the electrical port module 300 is disengaged from the cage of the host computer, thereby releasing the engaging relationship between the electrical port module 300 and the host computer and realizing the unlocking of the electrical port module 300.

[0055] In some embodiments, the engaging component of the electrical port module 300 can be provided on the surface of the unlocker 420; in some embodiments, the engaging component of the electrical port module 300 can be provided on the surface of the upper housing 310. In the present application, taking the engaging component of the electrical port module 300 being provided on the surface of the upper housing 310 as an example for exemplary illustration, exemplarily, an engaging component 318 is formed on the surface of the upper housing 310.

[0056] To cooperate with the unlocking component 400 in the present application, a corresponding structure for setting the unlocking handle 410 is formed at the end of the upper housing 310. A space for setting the unlocker 420 is formed on the surface of the upper housing 310, and the unlocker 420 can slide along the upper housing 310 to relatively approach the engaging component 318 to achieve unlocking. In some embodiments, on the surface of the upper housing 310, for example, the surface at one end of the upper housing 310 near the optical port is disconnected to respectively form a first flat plate 311 and a second flat plate 312 on both sides. The first flat plate 311 and the second flat plate 312 are oppositely arranged and not connected, and there is a gap 319 therebetween. The gap 319 is used to accommodate the unlocker 420. A first guide rail 313 is formed on the side wall of the first flat plate 311 facing the gap 319, and a second guide rail 314 is formed on the side wall of the second flat plate 312 facing the gap 319. The first guide rail 313 and the second guide rail 314 are oppositely arranged and not connected, and they are respectively used to enable the unlocker 420 to slide along them. A first rotating shaft 315 is formed on one side of the first flat plate 311, and a second rotating shaft 316 is formed on one side of the second flat plate 312. The first rotating shaft 315 and the second rotating shaft 316 are used to nest and set the unlocking handle 410, and provide a rotating shaft for the rotation of the unlocking handle 410, so as to realize the rotational connection between the unlocking handle 410 and the upper housing 310. For example, the first rotating shaft 315 and the first flat plate 311 are connected by a connecting arm, and the second rotating shaft 316 and the second flat plate 312 are also connected by a connecting arm. For example, the first rotating shaft 315 and the second rotating shaft 316 face the same direction to facilitate nesting the unlocking handle 410.

[0057] Figure 5 Structural diagram of an optical network terminal cage according to some embodiments. As Figure 5 shown, in some embodiments, at the port of the cage of the host computer, such as the cage 106 of the optical network terminal 100, there is a spring piece 1061 that matches the engaging component of the unlocking component 400. The spring piece 1061 includes a fixed end and a free end. The fixed end is used to be fixed on the cage 106, and the free end can move up and down. A card interface 1062 is opened on the surface of the free end, and the card interface 1062 matches the engaging component 318. When the engaging component 318 is engaged in the card interface 1062, the electrical port module 300 is fixed in the host computer, thereby realizing the locking of the electrical port module 300; when the engaging component 318 disengages from the card interface 1062, the electrical port module 300 is detached from the host computer, thereby realizing the unlocking of the electrical port module 300.

[0058] In some embodiments, when the spring piece 1061 remains relatively stationary, its free end is inclined relative to the fixed end. At this time, the surface of the spring piece 1061 is an inclined plane. The spring piece 1061 in the form of an inclined plane is more conducive to realizing the unlocking of the electrical port module 300 than the spring piece in the form of a flat plane.

[0059] When unlocking the electrical interface module 300, there are many ways to release the engagement relationship between the electrical interface module 300 and the host computer. In some embodiments, while keeping the host computer cage relatively fixed, the engaging component 318 sinks, so that the electrical interface module 300 actively disengages from the elastic piece 1061, realizing the disconnection between the electrical interface module 300 and the host computer; in some embodiments, while keeping the engaging component 318 relatively fixed, the elastic piece 1061 is pushed upward, causing the electrical interface module 300 to passively disengage from the elastic piece 1061, realizing the disconnection between the electrical interface module 300 and the host computer. In the present application, since the engaging component 318 is provided on the surface of the upper housing 310 and not on the surface of the unlocker 420, in some embodiments, the electrical interface module 300 can be unlocked by keeping the engaging component 318 relatively fixed and pushing the elastic piece 1061 upward.

[0060] In some embodiments, when the unlocking handle 410 remains in the natural hanging state, the unlocker 420 remains relatively stationary, and there is a certain distance between the unlocker 420 and the engaging component 318. Then the unlocker 420 cannot act on the engaging component 318 and the elastic piece 1061, and thus cannot disengage the two, so that the electrical interface module 300 remains in the locked state.

[0061] In some embodiments, when unlocking the electrical interface module 300, in the direction of the upper housing 310, that is, when pulling the unlocking handle 410 upward, the unlocker 420 can slide along the upper housing 310 towards the engaging component 318 and the elastic piece 1061 under the action of the thrust. Then the sliding unlocker 420 gradually approaches the engaging component 318 and the elastic piece 1061, and then gradually pushes up the elastic piece 1061 until the elastic piece 1061 is disengaged from the engaging component 318, thus realizing the unlocking of the electrical interface module 300.

[0062] Figure 6 It is a structural diagram of an unlocking component according to some embodiments. As Figure 6 shown, in some embodiments, the unlocking component 400 includes an unlocking handle 410 and an unlocker 420 which are connected to each other. The unlocking handle 410 is rotatably connected to the upper housing 310, and the unlocker 420 is slidably connected to the upper housing 310. When pulling the unlocking handle 410 upward along the side wall of the upper housing 310, the unlocking handle 410 rotates relative to the upper housing 310. During the rotation of the unlocking handle 410, the unlocker 420 is driven to move along the first guide rail 313 and the second guide rail 314 towards the engaging component 318 and the elastic piece 1061. The gradually moving unlocker 420 slowly acts on the elastic piece 1061, slowly pushes up the elastic piece 1061 until the elastic piece 1061 is disengaged from the engaging component 318, and the engaging component 318 is passively disengaged from the elastic piece 1061, thus realizing the unlocking of the electrical interface module 300.

[0063] In some embodiments, in order to limit the unlocking handle 410 to the side wall of the upper housing 310, first nesting holes 414 and second nesting holes 415 are respectively formed on both sides of the surface of the unlocking handle 410. The first nesting hole 414 is nested on the first rotating shaft 315, and the second nesting hole 415 is nested on the second rotating shaft 316, thereby limiting the unlocking handle 410 to the side wall of the upper housing 310 and enabling it to rotate along the first rotating shaft 315 and the second rotating shaft 316.

[0064] In some embodiments, the unlocker 420 includes a body structure 421, and the body structure 421 is disposed between the first flat plate 311 and the second flat plate 312. In order to enable the unlocker 420 to be pushed toward the engaging member 318 and the elastic piece 1061 when the unlocking handle 410 is rotated, a boss 411 is formed on the surface of the unlocking handle 410. The boss 411 is disposed between the first nesting hole 414 and the second nesting hole 415. When the unlocking handle 410 is rotated, the boss 411 rotates accordingly, and a thrust is applied to the end face of the body structure 421 during the rotation of the boss 411, thereby pushing the unlocker 420 to move, so that the unlocker 420 gradually approaches the engaging member 318 and the elastic piece 1061, thereby acting on the elastic piece 1061 to lift the elastic piece 1061, and further realizing the unlocking of the electrical port module 300. Exemplarily, in order to increase the smoothness of the acting force during the movement of the unlocker 420 pushed by the boss 411 during the rotation process, the surface of the boss 411 in contact with the unlocker 420 is a smooth curved surface, thereby reducing the friction between the two and increasing the smoothness.

[0065] In some embodiments of the present application, when the boss 411 cooperates with the body structure 421, whether the surfaces of the boss 411 and the body structure 421 are flush affects the fit. Due to machining errors and assembly errors, there is a certain height difference between the surfaces of the boss 411 and the unlocker 420, which affects the interaction between the two. When the contact area between the boss 411 and the unlocker 420 is large, this effect is particularly obvious. At the same time, when the contact area between the boss 411 and the body structure 421 is large, the acting force is more dispersed, which is not conducive to generating an effective unlocking stroke. Therefore, in some embodiments, the end of the body structure 421 extends the first arm 422 towards the unlocking handle 410. To cooperate with the first arm 422, a notch 412 is formed by recessing one surface of the boss 411. The notch 412 rotates as the unlocking handle 410 rotates. As the notch 412 rotates, the notch 412 exerts pressure on the first arm 422. Under the pressure, the first arm 422 slides along the inside of the notch 412. When the first arm 422 slips out of the notch 412, it continues to be abutted by the side wall 418 connected to the notch 412, causing the first arm 422 to move towards the engaging member 318, thereby pushing the unlocker 420 towards the position where the elastic piece 1061 is located, generating a certain unlocking stroke. The contact area between the first arm 422 and the notch 412 is relatively smaller than the contact area between the boss 411 and the body structure 421, thereby reducing the influence of the non-flush surfaces of the boss 411 and the body structure 421 on the interaction. At the same time, the acting force is concentrated on the acting surface between the first arm 422 and the notch 412, making the acting force more concentrated and conducive to generating an effective unlocking stroke. At the same time, due to the setting of the notch 412, when the electrical port module 300 is in the locked state, the unlocker 420 is closer to the unlocking handle 410, and thus farther away from the engaging member 318 and the elastic piece 1061, so it will not act on the elastic piece 1061 and will not damage the engagement relationship between the elastic piece 1061 and the engaging member 318, thereby keeping the electrical port module 300 in the locked state.

[0066] When the shape of the notch 412 is L-shaped, it has good openness, so that when the notch 412 and the first arm 422 are separated, the unlocker 420 can be disengaged from the notch 412 and is no longer restricted by the notch 412.

[0067] In some embodiments, when the electrical port module 300 is in the locked state, a certain distance should be maintained between the unlocker 420 and the elastic piece 1061. Otherwise, the electrical port module 300 will be unlocked, destroying the current locked state. Exemplarily, when the electrical port module 300 is in the locked state, a relatively long distance is maintained between the unlocker 420 and the elastic piece 1061. To ensure that a relatively long distance is maintained between the unlocker 420 and the elastic piece 1061 when the electrical port module 300 is in the locked state, the first arm 422 is of a relatively short length, so as to shorten the relative length of the unlocker 420 when the electrical port module is in the locked state, thereby lengthening the distance from the elastic piece 1061, so as to avoid acting on the elastic piece 1061 and maintaining the locked state of the electrical port module. Correspondingly, the notch 412 is located on the side of the boss 411 facing the engaging component 318, and the notch 412 is relatively closer to the engaging component 318.

[0068] In some embodiments, sufficient unlocking travel should be provided when unlocking the electrical port module 300, so that the unlocker 420 can completely lift the elastic piece 1061, thereby completely separating the elastic piece 1061 from the engaging component 318 to achieve successful unlocking. When the first arm 422 is a short arm with a relatively short length, when the unlocking handle 410 is pulled to a certain height, the notch 412 and the first arm 422 will be staggered from each other and no longer in contact and connection. The first arm 422 is no longer squeezed, and at this time, no further unlocking travel will be generated. Exemplarily, at a certain moment, the first arm 422 will disengage from the notch 412, and the two will be disconnected from contact, so that the notch 412 will no longer continue to push the first arm 422 to generate unlocking travel.

[0069] In some embodiments, in order to generate a continuous and sufficient unlocking stroke, in the boss 411, a groove 413 is formed by recessing one surface opposite to the surface where the notch 412 is located. Exemplarily, one surface of the boss 411 is recessed towards the inside of the boss 411 to form the notch 412, and the other surface of the boss 411 is also recessed towards the inside of the boss 411 to form the groove 413. The groove 413 and the notch 412 are located at the diagonal positions of the boss 411, and the groove 413 is farther from the engaging member 318 than the notch 412. The recessed directions of the groove 413 and the notch 412 are opposite to each other, and the opening directions of the groove 413 and the notch 412 are different. Exemplarily, the opening of the notch 412 faces the side where the engaging member 318 is located, and the opening of the groove 413 faces away from the side where the engaging member 318 is located. Matching with the groove 413, a second arm 423 also extends from the end face of the body structure 421 towards the unlocking handle 410. For the convenience of extension, the second arm 423 extends from the side wall of the body structure 421, and the second arm 423 is provided on the side of the body structure 421. Since the groove 413 is farther from the engaging member 318 than the notch 412, that is, the groove 413 is farther from the body structure 412 than the notch 412, the second arm 423 extends from the side wall of the body structure 421, and a bending portion 424 is formed by bending the end of the second arm 423. The length of the second arm 423 is relatively long. Exemplarily, it has a preset length such that the bending portion 424 crosses the side surface of the boss 411 until it reaches the position where the groove 413 is located, so as to extend the bending portion 424 to the groove 413. Exemplarily, the second arm 423 is bent and connected to the bending portion 424, and the end of the second arm 423 is bent inward to form the bending portion 424.

[0070] The groove 413 is farther from the engaging member 318 than the notch 412. Correspondingly, the bending portion 424 is farther from the engaging member 318 than the first arm 422. The second arm 423 extends the bending portion 424 at its end to the position where the groove 413 is located, so that the groove 413 and the bending portion 424 interact with each other, and the notch 412 and the first arm 422 interact with each other. Since the notch 412 is closer to the groove 413, the length of the first arm 422 is relatively shorter than the length of the second arm 423.

[0071] As the unlocking handle 410 rotates, the notch 412 rotates accordingly. The rotating notch 412 exerts pressure on the first arm 422, thereby pushing the first arm 422 to move. Since the length of the first arm 422 is relatively short, for example, the length of the first arm 422 is less than the length of the second arm 423, during the rotation of the notch 412, the connection between the first arm 422 and the notch 412 will be disconnected due to misalignment, and the connection between the first arm 422 and the side wall 418 will also be disconnected due to misalignment. At this time, the first arm 422 is no longer under force, and the unlocker 420 cannot be moved further. In order to completely lift the elastic piece 1061 and completely separate the elastic piece 1061 from the engaging component 318, in this application, through the cooperation of the groove 413 and the bending portion 424, as the first arm 422 moves, the bending portion 424 enters the groove 413. The groove 413 rotates as the unlocking handle rotates. At this time, the inner wall of the groove 413 exerts pressure on the bending portion 424, causing the second arm 423 to move towards the engaging component 318. Even if the notch 412 no longer acts on the first arm 422 to generate an unlocking stroke, the unlocking process can still continue until the elastic piece 1061 is completely lifted and the electrical port module is disengaged from the host computer.

[0072] In this application, the first arm 422 is squeezed by the notch 412 at the very beginning of the rotation of the unlocking handle 410, driving the movement of the body structure 421. During the movement of the first arm 422, the bending part 424 enters the groove 413. At this time, the bending part 424 is squeezed by the groove 413, driving the movement of the second arm 423, and the movement of the second arm 423 drives the movement of the body structure 421. In this application, through the force on the first arm 422 and the bending part 424, an unlocking stroke is continuously generated, thereby increasing the unlocking stroke and achieving complete unlocking. The first arm 422 is relatively short, and then the second arm 423 extends from the side over the boss 411. This design can make the first arm 422 and the second arm 423 more concentrated, which is beneficial to the miniaturization of the size. At the same time, when in the locked state, it is far away from the engaging component 318 and maintains a certain distance from the engaging component 318, thus avoiding acting on the elastic piece and destroying the locked state. Assuming that only the first arm 422 is used for unlocking, the length of the first arm 422 is relatively long, which is not conducive to the miniaturization of the size and cannot keep a long distance from the engaging component 318. Assuming that only the second arm 423 is used for unlocking, the second arm 423 has to be stressed at the very beginning of the rotation of the unlocking handle 410, which is not conducive to generating a long unlocking stroke. In this application, through the progressive force of the relatively short first arm 422 and the second arm 423 extending from the side, a progressive unlocking stroke is generated, providing a continuous and sufficient unlocking stroke. The design of this application is ingenious, which is beneficial to the miniaturization of the size; and a long unlocking stroke is generated, thus achieving complete unlocking. In some embodiments, the progressive unlocking can be that when the first arm 422 stops being stressed, the bending part 424 is stressed; in some embodiments, the progressive unlocking can also be that before the first arm 422 stops being stressed, the bending part 424 has already started to be stressed.

[0073] The shape of the groove 413 can be U-shaped, which has good wrapping property to prevent the bending part 424 from slipping out of the groove 413, increasing the moving time of the bending part 424 in the groove 413, thereby generating a long unlocking stroke and achieving complete unlocking of the electrical interface module 300.

[0074] When the electrical interface module 300 is in the locked state, the bending part 424 does not contact the groove 413 to maintain the locked state of the electrical interface module 300. When the unlocking handle 410 is rotated to a certain height, the bending part 424 starts to contact the groove 413. As the unlocking handle 410 rotates, the extrusion between the groove 413 and the bending part 424 will push the unlocker 420 towards the engaging component 318 and the elastic piece 1061, thereby increasing the unlocking stroke, providing a continuous and sufficient unlocking stroke until the elastic piece 1061 is completely lifted and the electrical interface module is disengaged from the host computer.

[0075] Figure 7The structure of an unlocking handle according to some embodiments Figure 1 ; Figure 8 The structure of an unlocking handle according to some embodiments Figure 2 . As Figure 7 and Figure 8 shown, in some embodiments, the unlocking handle 410 includes a fixed end and a free end. The fixed end is fixed to the upper housing 310. The fixed end is the end of the unlocking handle 410 that is connected to the upper housing 310. On both sides of this end, a notch 412 and a groove 413 are respectively formed. The free end of the unlocking handle 410 is freely arranged relative to the upper housing 310. When the free end is pulled upward, the unlocking handle 410 rotates along the side wall of the upper housing 310. The boss 411 is located at the fixed end of the unlocking handle 410. The notch 412 and the groove 413 are respectively provided on two different surfaces of the boss 411. Exemplarily, the notch 412 is farther from the engaging component than the groove 413.

[0076] In order to limit the unlocking handle 410 to the side wall of the upper housing 310, first nested holes 414 and second nested holes 415 are respectively formed on both sides of the surface of the fixed end of the unlocking handle 410. The first nested hole 414 is nested on the first rotating shaft 315, and the second nested hole 415 is nested on the second rotating shaft 316, thereby limiting the unlocking handle 410 to the side wall of the upper housing 310. At the same time, the unlocking handle 410 can rotate along the first rotating shaft 315 and the second rotating shaft 316. In order to avoid some structures, a first avoidance portion 416 is formed on one side of the second nested hole 415, and a second avoidance portion 417 is formed on one side of the first nested hole 414.

[0077] In some embodiments, in order to increase the smoothness of unlocking, the notch 412 includes a first accommodating cavity 4121 and a first rounded corner 4122. The first accommodating cavity 4121 is used to accommodate the first arm 422. The first rounded corner 4122 is located at the top of the first accommodating cavity 4121. As the unlocking handle 410 rotates, the opening of the notch 412 rotates downward. During the rotation, the first rounded corner 4122 comes into contact with the first arm 422, and the inner wall of the notch 412 presses the first arm 422. During the pulling process, the first rounded corner 4122 acts tangentially with the first arm 422, and with the tangent point of the two as the fulcrum, thereby pushing the unlocker 420 forward. "Pushing the unlocker 420 forward" means pushing the unlocker 420 in the direction towards the engaging component 318 and the elastic piece 1061. When the first rounded corner 4122 is separated from the first arm 422, the side wall 418 connected to the notch 412 will abut against the first arm 422 until the side wall 418 is separated from the first arm, and the first arm 422 will no longer be stressed and thus cannot drive the body structure to move. Due to the smooth surface of the first rounded corner 4122, the tangential movement friction between the first rounded corner 4122 and the first arm 422 is smoother, and thus the unlocking process is smoother.

[0078] In some embodiments, to increase the smoothness of unlocking, the groove 413 includes a second receiving cavity 4131, a second rounded corner 4132, and a curved surface 4133. As the unlocking handle 410 rotates, the opening of the groove 413 rotates upward, and the curved surface 4133 begins to contact the bent portion 424. The curved surface 4133 presses the bent portion 424, thereby pushing the bent portion 424 toward the second rounded corner 4132. As the unlocking handle 410 continues to rotate, the bent portion 424 contacts the second rounded corner 4132, and the two also perform a tangential movement. Taking the tangent point of the two as the fulcrum, the bent portion 424 is moved toward the second receiving cavity 4131. The second receiving cavity 4131 presses the bent portion 424, thereby causing the bent portion 424 to push the unlocker 420 toward the engaging component 318 and the elastic piece 1061 until the unlocker 420 completely lifts the elastic piece 1061 and completely disengages the elastic piece 1061 from the engaging component 318, thereby releasing the engagement relationship between the electrical port module 300 and the host computer and disengaging the electrical port module 300 from the host computer to achieve the unlocking of the electrical port module 300.

[0079] In some embodiments, to ensure that an unlocking stroke occurs when the notch 412 presses the first arm 422, the inner wall dimension of the notch 412 along the height direction of the upper housing 310 is greater than the inner wall dimension of the notch 412 along the length direction of the upper housing 310. Among them, the inner wall dimension of the notch 412 along the height direction of the upper housing 310 is Figure 7 the line segment H marked in Figure 7 ; the inner wall dimension of the notch 412 along the length direction of the upper housing 310 is

[0080] Figure 9 The structure of an unlocker according to some embodiments Figure 1 ; Figure 10 The structure of an unlocker according to some embodiments Figure 2 ; Figure 11 The sectional structure diagram of an unlocker according to some embodiments. As Figures 9 - 11 shown, in some embodiments, the bent portion 424 is a hemispherical arm, the top surface of the bent portion 424 is a plane, and a hemispherical surface is formed downward around the top surface, so that the force-bearing surface between the bent portion 424 and the groove 413 is more concentrated and other force-bearing surfaces are avoided.

[0081] In some embodiments, both the second arm 423 and the first arm 422 extend relative to the end surface of the body structure 421. Exemplarily, the length by which the second arm 423 extends relatively is greater than the length by which the first arm 422 extends relatively. Since the second arm 423 extends a longer length, it can ensure that the bent portion 424 crosses the side surface of the boss 411 and thus extends to the groove 413. The length by which the second arm 423 extends relatively is like the line segment n marked in Figure 9 and the length by which the first arm 422 extends relatively is like the line segment m marked in Figure 9 . Obviously, the length of the line segment n is greater than the length of the line segment n. In this application, two arms with different extended lengths result in a progressive unlocking path, which is beneficial for miniaturization of the size and can provide a longer unlocking stroke.

[0082] In some embodiments, the extending directions of the first arm 422 and the bent portion 424 are different. The extending direction of the first arm 422 is consistent with the length direction of the body structure 421, and the extending direction of the bent portion 424 is consistent with the width direction of the body structure 421.

[0083] In some embodiments, the lengths of the first arm 422 and the second arm 423 can be designed according to the expected unlocking stroke, so as to achieve the expected unlocking stroke and realize the complete unlocking of the electrical interface module 300.

[0084] In some embodiments, in order to enable the unlocker 420 to slide along the upper housing 310 and thus move towards the engaging component 318 and the elastic piece 1061, a first sliding groove 426 and a second sliding groove 425 are respectively formed on both sides of the body structure 421. As described above, the end surface of the upper housing 310 near the optical port is disconnected to respectively form a first flat plate 311 and a second flat plate 312 on both sides. The first flat plate 311 and the second flat plate 312 are arranged opposite to each other and not connected, and there is a gap 319 therebetween. The gap 319 is used to accommodate the unlocker 420. A first guide rail 313 is formed on the side wall of the first flat plate 311 facing the gap 319, and a second guide rail 314 is formed on the side wall of the second flat plate 312 facing the gap 319. The first sliding groove 426 is slidably connected to the first guide rail 313, and the second sliding groove 425 is slidably connected to the second guide rail 314. Therefore, when the unlocking handle 410 is pulled upward, under the action of the thrust force, the first sliding groove 426 slides along the first guide rail 313 towards the engaging component 318 and the elastic piece 1061, and the second sliding groove 425 slides along the second guide rail 314 towards the engaging component 318 and the elastic piece 1061, so that the unlocker 420 acts on the surface of the elastic piece 1061 and jacks up the elastic piece 1061, thereby realizing the unlocking of the electrical interface module 300. Exemplarily, the lengths of the first sliding groove 426 and the second sliding groove 425 depend on the unlocking stroke required for the electrical interface module 300 to achieve unlocking.

[0085] When the electrical interface module 300 is in the locked state, to prevent the electrical interface module 300 from being unlocked, a certain distance should be maintained between the electrical interface module 300 and the engaging component 318 at this time. Then the unlocker 420 should have a preset length. To ensure the unlocking stroke, the lengths of the first chute 426 and the second chute 425 should also have preset lengths. As a result, the length left for the first arm 422 is limited, and the end of the first arm 422 is connected to the surface of the boss 411. Therefore, the first arm 422 is limited between the boss 411 and the body structure 421, which also leads to a relatively short set length of the first arm 422, making it a short arm. At the same time, it is necessary to ensure that the unlocker 420 is relatively closer to the unlocking handle 410 to increase the distance between the unlocker 420 and the engaging component 318 when the electrical interface module 300 is in the locked state, so the set length of the first arm 422 cannot be too long. Therefore, whether from the mechanical setting relationship or the unlocking principle, the length of the first arm 422 cannot be too long.

[0086] In some embodiments, one end of the body structure 421 is respectively formed with a first arm 422 and a bent portion 424, and the other end is formed with a connection plane 428. The two ends of the connection plane 428 are respectively formed with a first inclined surface 429a and a second inclined surface 429b. When it is necessary to unlock the electrical interface module 300, rotate the unlocking handle 420, and at the same time drive the unlocker 420 to move towards the positions where the engaging component 318 and the elastic piece 1061 are located. Then the first inclined surface 429a and the second inclined surface 429b also move towards the positions where the engaging component 318 and the elastic piece 1061 are located. During the movement, the first inclined surface 429a and the second inclined surface 429b respectively come into contact with both sides of the elastic piece 1061. The thrust applied by the unlocking handle 410 acts on the first inclined surface 429a and the second inclined surface 429b. According to the decomposition of the acting force, the thrust on the first inclined surface 429a and the second inclined surface 429b can be decomposed into horizontal and vertical component forces perpendicular to each other. Under the action of the horizontal component force, the unlocker 420 moves forward, and under the action of the vertical component force, the elastic piece 1061 is pushed upward. As the unlocking handle 410 rotates, the unlocker 420 is pushed forward. During the pushing process, the first inclined surface 429a and the second inclined surface 429b come into contact with the elastic piece 1061 and act on the elastic piece 1061. The contact surfaces of the two inclined surfaces with the elastic piece 1061 gradually rise as the unlocker 420 moves forward. Then the free end of the elastic piece 1061 can be pushed up through the gradually rising contact surfaces until the elastic piece 1061 is disengaged from the engaging component 318. At the same time, exemplarily, the first inclined surface 429a and the second inclined surface 429b are not connected and have a certain gap to avoid the engaging component 318 when disengaging from the engaging component 318.

[0087] In some embodiments, the elastic piece 1061 is in an inclined state. Exemplarily, the height of the free end of the elastic piece 1061 is higher than the height of the fixed end of the elastic piece 1061. In order to enable the first inclined surface 429a and the second inclined surface 429b to contact the elastic piece 1061 starting from its bottom, so as to act on the elastic piece 1061, the height of the connection plane 428 should be lower than the height of the body structure 421, so as to sink the surface where the first inclined surface 429a and the second inclined surface 429b are located, so that the first inclined surface 429a and the second inclined surface 429b are in contact with the elastic piece 1061 from the very beginning, extending the contact duration with the elastic piece 1061, so as to ensure that the elastic piece 1061 is effectively lifted and completely lifted until the elastic piece 1061 is separated from the engaging component 318, so as to unlock the electrical port module 300 from the host computer. For this purpose, a connecting inclined surface 427 is connected between the body structure 421 and the connection plane 428, and the body structure 421 and the connection plane 428 are connected by the connecting inclined surface 427, so as to ensure effective action on the elastic piece 1061. Exemplarily, the connecting inclined surface 427 is inclined so that the surface of the body structure 421 is higher than the surface of the connection plane 428, and the inclination angle of the connecting inclined surface 427 can be determined according to the position of the engaging component 318.

[0088] Figure 12 It is a structural diagram of an upper shell according to some embodiments. As Figure 12 shown, in some embodiments, a first rotating shaft 315 is formed on one side of the first flat plate 311, and a second rotating shaft 316 is formed on one side of the second flat plate 312. Both the first rotating shaft 315 and the second rotating shaft 316 bend and extend relative to the side wall of the upper shell 310. Exemplarily, their extending directions are the same to facilitate nesting the unlocking handle 410. In order to limit the unlocking handle 410, a limiting groove 3161 is formed on the second rotating shaft 316, and a limiting structure is arranged on the surface of the limiting groove 3161 to limit and fix the unlocking handle 410. Exemplarily, the limiting structure can be a limiting piece.

[0089] Figure 13 It is a sectional view of an electrical port module according to some embodiments. As Figure 13As shown, in some embodiments, the body structure 421 of the unlocker 420 is disposed between the first flat plate 311 and the second flat plate 312. A first guide rail 313 is formed on the side wall of the first flat plate 311 facing the gap 319, and a second guide rail 314 is formed on the side wall of the second flat plate 312 facing the gap 319. A first sliding groove 426 and a second sliding groove 425 are respectively formed on both sides of the body structure 421. The first sliding groove 426 is slidably connected to the first guide rail 313, and the second sliding groove 425 is slidably connected to the second guide rail 314. Therefore, when the unlocking handle 410 is pulled upward, under the action of the thrust, the first sliding groove 426 slides along the first guide rail 313 toward the engaging member 318 and the elastic piece 1061, and the second sliding groove 425 slides along the second guide rail 314 toward the engaging member 318 and the elastic piece 1061, so that the unlocker 420 acts on the surface of the elastic piece 1061 to lift the elastic piece 1061, thereby realizing the unlocking of the electrical port module 300.

[0090] Figure 14 A structural diagram of the end of an electrical port module according to some embodiments. As Figure 14 shown, in some embodiments, in order to limit the unlocking handle 410, a limiting groove 3161 is formed on the second rotating shaft 316, and a limiting piece 317 is disposed on the surface of the limiting groove 3161 to limit the unlocking handle 410 on the upper housing 310 and prevent the unlocking handle 410 from slipping out of the upper housing 310.

[0091] A first avoidance portion 416 is formed on one side of the second nested hole 415 for avoiding the limiting piece 317; a second avoidance portion 417 is formed on one side of the first nested hole 414 for avoiding the side wall of the upper housing 310.

[0092] Figure 15 An unlocking process diagram of an unlocking component according to some embodiments. As Figure 15 shown, in some embodiments, when the unlocking handle 410 is rotated upward, the unlocking handle 410 pushes the unlocker 420 to move forward to approach the engaging member 318 and the elastic piece 1061, and the first inclined surface 429a and the second inclined surface 429b of the unlocker 420 are respectively in contact with both sides of the elastic piece 1061; during the forward movement of the unlocker 420, the surfaces of the first inclined surface 429a and the second inclined surface 429b gradually act on the elastic piece 1061, and the free end of the elastic piece 1061 can be lifted by the gradually rising contact surface until the elastic piece 1061 is separated from the engaging member 318, realizing the unlocking of the electrical port module 300. Herein, "forward movement" means that the unlocker 420 moves toward the position where the engaging member 318 is located.

[0093] When the unlocking handle 410 is in the natural drooping state, the electrical port module 300 is inserted into the cage of the host computer. At this time, since the distance between the unlocker 420 and the elastic piece 1061 is relatively far and cannot act on the elastic piece 1061, the locking state of the electrical port module 300 is maintained at this time. When the unlocking handle 410 is pulled to a relatively high height, the unlocker 420 contacts the elastic piece 1061 and acts on the elastic piece 1061 until the elastic piece 1061 is pushed up to unlock the electrical port module 300.

[0094] Figure 16 The unlocking principle of an unlocking component according to some embodiments Figure 1 . As Figure 16 shown, the process shown is the process of the interaction between the notch 412 and the first arm 422 during the unlocking process of rotating the unlocking handle 410. Before the unlocking handle 410 is pulled, the first arm 422 is disposed in the notch 412 to maintain the stability of the unlocker 420. As the unlocking handle 410 is gradually lifted, the opening of the notch 412 gradually moves downward. During this movement process, the first rounded corner 4122 of the notch 412 abuts against the first arm 422 and moves it forward. The notch 412 exerts extrusion on the first arm 422. Under the extrusion, the first arm 422 moves forward until it disengages from the notch 412, and then is abutted by the side wall 418 and moves forward. When the first arm 422 no longer contacts the side wall 418, the first arm 422 is no longer under extrusion and cannot continue to push the first arm 422 forward. Exemplarily, at a certain moment, the notch 412 and the first arm 422 may be offset up and down, such as the first arm 422 being located obliquely above the notch 412, and the connection relationship is disconnected, so that the unlocker 420 cannot be pushed forward continuously.

[0095] Figure 17 The unlocking principle of an unlocking component according to some embodiments Figure 2 . As Figure 17As shown, the process shown is the process of interaction between the groove 413 and the bent portion 424 during the process of pulling the unlocking handle 410 to unlock. Before the unlocking handle 410 is pulled, the groove 413 and the bent portion 424 cannot contact each other, otherwise a certain unlocking stroke will be generated for the electrical port module 300, destroying the locked state of the electrical port module 300 at this time. As the unlocking handle 410 is gradually lifted, the opening of the groove 413 rotates upward, and the curved surface 4133 begins to contact the bent portion 424, pushing the bent portion 424 to move toward the second fillet 4132. As the unlocking handle 410 continues to rotate, the bent portion 424 contacts the second fillet 4132, and the two also make tangential motion. With the tangent point of the two as the fulcrum, the bent portion 424 is moved toward the second accommodating cavity 4131. The rotating second accommodating cavity 4131 squeezes the bent portion 424, thereby causing the second arm 423 to move forward and driving the main body structure 421 to move at the same time, until the unlocking device 420 completely lifts the spring piece 1061 and completely separates the spring piece 1061 from the engaging component 318, thereby releasing the engaging relationship between the electrical port module 300 and the host computer, separating the electrical port module 300 from the host computer, and realizing the unlocking of the electrical port module 300.

[0096] In some embodiments, as the unlocking handle 410 is gradually lifted, the curved surface 4133 begins to contact the bending portion 424. At this time, the first arm 422 is still connected to the notch 412, that is, the time point when the notch 412 is disconnected from the first arm 422 is later than the time point when the curved surface 4133 and the bending portion 424 are in contact with each other, so as to ensure the continuity of unlocking.

[0097] Figure 18 The unlocking initial state of an unlocking component according to some embodiments Figure 1 ; Figure 19 The unlocking initial state of an unlocking component according to some embodiments Figure 2 .like Figure 18 and Figure 19 As shown, before the unlocking handle 410 is pulled, the first arm 422 is disposed in the notch 412 to maintain the stability of the unlocking device 420. Before the unlocking handle 410 is pulled, the groove 413 and the bent portion 424 cannot come into contact with each other, otherwise a certain unlocking stroke will be generated for the electrical port module 300, destroying the locked state of the electrical port module 300 at this time.

[0098] Figure 20 An unlocking intermediate state of an unlocking component according to some embodiments Figure 1 ; Figure 21 An unlocking intermediate state of an unlocking component according to some embodiments Figure 2 .like Figure 20 andFigure 21 As shown, as the unlocking handle 410 rotates, the opening of the groove 413 rotates upward, and the curved surface 4133 begins to contact the bent portion 424. The curved surface 4133 presses against the bent portion 424, thereby pushing the bent portion 424 toward the second rounded corner 4132. As the unlocking handle 410 continues to rotate, the bent portion 424 contacts the second rounded corner 4132, and the two also perform a tangential movement. Taking the tangent point of the two as the fulcrum, the bent portion 424 is moved toward the second receiving cavity 4131. The second receiving cavity 4131 presses against the bent portion 424, thereby causing the bent portion 424 to push the unlocker 420 in the direction of the engaging member 318 and the elastic piece 1061.

[0099] Figure 22 The final unlocking state of an unlocking component according to some embodiments Figure 1 ; Figure 23 The final unlocking state of an unlocking component according to some embodiments Figure 2 ; Figure 24 The final unlocking state of an unlocking component according to some embodiments Figure 3 . As Figures 22 - 24 shown, when the unlocking is completed, the bent portion 424 is within the groove 413. At this time, the first arm 422 has disengaged from the notch 412 and is no longer connected.

[0100] In the electrical interface module provided by the present application, it includes an upper housing and an unlocking component. The surface of the upper housing has a clamping component, which is clamped and connected to the elastic piece of the host computer through the clamping component, so as to clamp the electrical interface module in the host computer. The unlocking component includes an unlocking handle and an unlocker. Among them, the unlocking handle is arranged at the end of the upper housing and is rotatably connected to the upper housing. One end of the unlocking handle forms a notch, and the other end forms a groove. Both the notch and the groove rotate as the unlocking handle rotates. The unlocker is slidably connected to the upper housing. The unlocker includes a body structure, and a first arm and a second arm respectively extend from the end face of the body structure facing the unlocking handle. The first arm is arranged in the notch. The second arm includes an extension arm and a bending part formed by bending the end of the extension arm. As the notch rotates, the notch applies pressure to the first arm, so that the first arm slides along the inner wall of the notch until it slips out of the notch, and then continues to abut against the side wall connected to the notch, causing the first arm to move towards the clamping component. When the electrical interface module is in the locked state, the first arm is arranged in the notch. In order to avoid the unlocker acting on the elastic piece and the clamping component at this time, the length of the first arm is short, so that the unlocker is as far away from the elastic piece and the clamping component as possible in the current state, so as to maintain the current locked state. When the length of the first arm is short, during the movement process, the connection between the first arm and the notch will be disconnected due to misalignment, until the connection between the first arm and the abutting side wall will also be disconnected due to misalignment, resulting in the first arm no longer being squeezed and no longer generating an unlocking stroke. Therefore, as the first arm moves, the bending part of the second arm enters the groove. During the rotation of the groove, the inner wall of the groove squeezes the bending part, causing the second arm to move towards the clamping component and continue to generate an unlocking stroke until the elastic piece is lifted, so that the clamping component is separated from the elastic piece, thereby releasing the clamping connection between the electrical interface module and the host computer. In the present application, the first arm and the second arm are respectively stressed to provide a continuous and sufficient unlocking stroke to completely separate the electrical interface module from the host computer and realize the unlocking of the electrical interface module. It can be understood that the optical module belongs to a type of electrical interface module, and the unlocking component provided by the present application is also applicable to the optical module, that is, the optical module can also adopt the unlocking component provided by the present application.
