Description

Technical Field

[0001] This invention relates to the field of optical communication technology, and in particular to an optoelectronic hybrid connector and its usage method. Background Technology

[0002] Optical fiber communication is a communication method that uses light waves as the information carrier and optical fibers as the transmission medium. The field of optical communication technology typically involves devices such as connectors, optical modules, and adapters.

[0003] Connectors are passive optical devices that enable connections between optical fibers. They function to connect optical fibers to each other, to active devices, to equipment, to other passive devices, and to instruments. Optical modules, as crucial optical signal interface devices in fiber optic communication, have both optical and electrical interfaces. The optical interface connects to the optical fiber to transmit optical signals, while the electrical interface connects to external communication terminal equipment. Adapters are used to convert between two connectors. Especially in fiber optic equipment such as 5G base stations and FTTR devices, where wideband communication requires remote power supply, numerous optoelectronic lines are involved. Because optoelectronic connections are separate, the number of connectors is large and divided into two categories, requiring correct pairing. This makes installation and maintenance cumbersome and prone to errors.

[0004] On the other hand, in Fiber To the Home (FTTH) networks, traditional copper wires at the network's terminal end not only transmit network signals but also provide power to the terminal. However, as FTTH optical networks evolve into FTTR optical networks, such as in-vehicle terminals requiring autonomous driving and AI interaction, the bandwidth demands at the terminal end are increasing, and traditional copper wire signal transmission capabilities can no longer meet these requirements. FTTR, with its terminal end signal transmission medium shifting from copper to optical fiber and power supplied by cables, is becoming the norm. To connect these composite cables, one existing solution is to design separate optical and electrical connectors. The optical connector is plugged into the optical adapter to achieve optical signal coupling, while the electrical connector is plugged into the electrical adapter to achieve electrical signal coupling. However, using separate optical and electrical connectors requires two plugging and unplugging cycles to complete the connection with the adapter. The solution is to use optoelectronic hybrid connectors and optoelectronic hybrid adapters. However, in some existing solutions, the electrical terminals of the connectors are exposed to the outside, which poses a certain risk of electric shock and human safety issues during actual use. Other solutions use claw-type terminals, which have problems such as large space occupation, high friction, low reliability of electrical terminal coupling, and insufficient current carrying capacity.

[0005] Furthermore, fiber optic connectors require micron-level alignment precision for their optical fibers. Any force applied outside the optical axis during coupling will affect both the coupling efficiency and accuracy. Existing electrical terminals are asymmetrically distributed in their fiber coupling structure. This asymmetry increases friction during connector insertion and removal, creating insertion and removal stress that impacts the coupling accuracy of the connector's optical channel. Moreover, existing male and female electrical terminals use a parallel multi-pin structure, which is space-consuming and material-intensive. In vibration scenarios, this parallel structure cannot guarantee contact between the male and female terminals, thus compromising the reliability of electrical coupling under vibration.

[0006] Therefore, overcoming the shortcomings of the existing technology is an urgent problem to be solved in this technical field. Summary of the Invention

[0007] The technical problem to be solved by the present invention is that the electrical terminals of existing optoelectronic hybrid connectors and optoelectronic hybrid adapters are asymmetrically distributed in the optical fiber coupling structure, resulting in low optical fiber coupling efficiency and coupling accuracy, and insufficient reliability of electrical terminal coupling.

[0008] The present invention adopts the following technical solution: In a first aspect, the present invention provides an optoelectronic hybrid connector, comprising a male connector 1 and a female connector 2 mated to its front end; The male connector 1 is internally configured with two male electrical terminals 14 arranged around the central axis. The two male electrical terminals 14 are symmetrically distributed. At least two spring claws 140 are arranged at the front end of the male electrical terminals 14, and the spring claws 140 are set at a preset angle. The female connector 2 is internally configured with two female electrical terminals 25 symmetrically distributed about the central axis. The rear end of the female electrical terminal 25 is provided with a spring piece 250. The spring piece 250 includes at least two planes 251 set at a preset angle. The male terminal 14 and the female terminal 25 correspond one-to-one. When the connector is working, at least one spring claw 140 abuts against the plane 251 to transmit electrical signals.

[0009] Furthermore, the male connector 1 includes a male ferrule assembly 11, and the male electrical terminals 14 are symmetrically arranged about the male ferrule assembly 11; The female connector 2 includes an optical coupling alignment member 22, and the female electrical terminals 25 are symmetrically arranged about the optical coupling alignment member 22. The male end ferrule assembly 11 is provided with an elastic retainer 110, which is used to apply axial elastic force to the male end ferrule assembly 11 and abut against the optical coupling alignment member 22.

[0010] Furthermore, a female ferrule assembly 21 is provided on the front side of the optical coupling alignment member 22, and the male ferrule assembly 11 and the female ferrule assembly 21 correspond one-to-one; The elastic retainer 110 is compressed and stores rebound force. Under the action of the rebound force, the male end ferrule assembly 11, the optical coupling alignment member 22, and the female end ferrule assembly 21 abut together in sequence to realize the coupling and transmission of optical signals.

[0011] Furthermore, the male connector 1 also includes a male housing 10, which is disposed at the front end of the male ferrule assembly 11. The male housing 10 includes a housing body 15 and a sleeve 16 at its front end. The outer casing body 15 has at least one stop window 150 on both sides. The male end insert assembly 11 is accommodated in the rear housing 13. The rear housing 13 has at least one snap-fit ​​platform 131 on both sides. The stop window 150 is used to snap the snap-fit ​​platform 131 to fix the outer casing body 15 and the rear housing 13.

[0012] Furthermore, a coupling support 151 is provided inside the outer shell body 15, and a through hole is provided in the center of the coupling support 151 for accommodating the front end of the male end ferrule assembly 11. The coupling support 151 is provided with first guide grooves 153 on both sides, and the male terminal 14 can be inserted into the first guide grooves 153 from the front end of the male housing 10. Alternatively, the male terminal 14 and the male housing 10 can be integrally injection molded using an insert molding method.

[0013] Furthermore, a first snap-fit ​​plate 142 is provided between the two spring claws 140 to fix it inside the outer shell body 15. The front end of the first snap-fit ​​plate 142 is provided with an abutment portion 141, the length of the front end of the abutment portion 141 being less than the length of the spring claw 140.

[0014] Furthermore, a limiting block 143 is provided on the upper surface of the abutment portion 141. The upper surface of the limiting block 143 is set as a slope at a preset angle to limit the axial movement distance of the male terminal 14 in the first guide groove 153.

[0015] Furthermore, the female terminal 25 includes a second snap-fit ​​plate 252 for fixing inside the female housing 20, and a connecting plate 253 extends perpendicularly to the second snap-fit ​​plate 252. The spring piece 250 is arranged perpendicularly to the plane 251 of the connecting plate 253.

[0016] Furthermore, the female end housing 20 is provided with an inner sleeve 26, and the inner sleeve 26 is provided with a second guide groove 207 for accommodating the female end electrical terminal 25, and the female end electrical terminal 25 can be inserted into the second guide groove 207 from the front end of the female end housing 20; Alternatively, the female terminal 25 and the female housing 20 can be integrally injection molded by insert molding.

[0017] Secondly, the present invention provides a method for using an optoelectronic hybrid connector, applicable to the aforementioned optoelectronic hybrid connector, comprising: The male terminal 14 is snapped into the interior of the housing body 15, and the female terminal 25 is also snapped into the interior of the female housing 20. Align the front end of male connector 1 and the tail end of female connector 2, and push male connector 1 horizontally forward to snap male connector 1 and female connector 2 together to achieve optical signal coupling. The male connector 1 and the female connector 2 are mated together, so that the male electrical terminal 14 and the female electrical terminal 25 abut together, that is, the spring claw 140 abuts against the inner surface of the spring piece 250, thereby achieving electrical terminal coupling.

[0018] The beneficial effects of this invention are as follows: By symmetrically arranging the electrical terminals, each contact is evenly distributed around the central optical axis in an approximately circular manner, resulting in a more balanced force on the optical coupling unit during coupling and docking, preventing lateral forces on the central optical axis, and improving the coupling efficiency and accuracy of the optical fiber. Furthermore, the electrical terminals employ a non-parallel structure, making the contact more reliable and stable. The male terminal uses a double-claw layout with a certain included angle, which, compared to the multiple-pin layout used in existing conventional technologies, reduces terminal pressure, saves metal materials, improves space utilization, and optimizes component costs.

[0026] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0027] Example 1: Embodiment 1 of the present invention provides an anti-accidental disconnection optoelectronic connector, see reference. Figure 1and Figure 2 The anti-accidental removal optoelectronic connector includes a male connector 1, a female connector 2, and an anti-accidental removal locking block 3. The male connector 1 includes a male housing 10, and an elastic cantilever 100 is provided on the upper surface of the male housing 10. The anti-accidental removal locking block 3 is slidably disposed on the upper surface of the male housing 10. The anti-accidental removal locking block 3 includes a locking block body 31 and at least one connecting arm 30 disposed at the front end of the locking block body 31. The male connector 1 and the female connector 2 are detachably snapped together by the elastic cantilever 100, and the connecting arm 30 slides to the locking protrusion 104 of the elastic cantilever 100 (e.g., ...). Figure 7 As shown below, the pressable stroke of the elastic cantilever 100 is less than the unlocking stroke.

[0028] See Figure 1 and Figure 2 In order to lock and unlock the male connector 1 and the female connector 2, the front end of the male connector 1 is provided with a male housing 10, and the upper surface of the male housing 10 is provided with an elastic cantilever 100. The elastic cantilever 100 extends backward, and the extension length is less than the length of the male housing 10.

[0029] In one embodiment, pressing down on the tail end of the elastic cantilever 100 causes the elastic cantilever 100 to elastically deform, aligning the male end housing 10 with the female end connector 2, and pushing the male end connector 1 forward; the male end housing 10 is provided with a fixing member 101, and the male end connector 1 is pushed forward until the fixing member 101 is in contact with the female end connector 2, the elastic cantilever 100 is released, the elastic cantilever 100 returns to its deformation, and is engaged with the female end connector.

[0030] After the male connector 1 is engaged with the female connector 2, at least one connecting arm 30 is pressed inward by the female connector 2. If external force is continued to be applied to the anti-mistake locking block 3, the anti-mistake locking block 3 can continue to slide towards the female connector 2, causing the connecting arm 30 to slide to the locking protrusion 104 of the elastic cantilever 100 (e.g., ...). Figure 7 As shown below, the pressable stroke of the elastic cantilever 100 is less than the unlocking stroke.

[0031] In one embodiment, pulling the anti-misoperation locking block 3 backward causes the connecting arm 30 to move away from below the locking protrusion 104 of the elastic cantilever 100. Pressing down on the tail end of the elastic cantilever 100 causes the elastic cantilever 100 to undergo elastic deformation. Pulling the male connector 1 backward causes the elastic cantilever 100 to disengage from the female connector 2, thus completing the unlocking process.

[0032] It should be noted here that, with Figure 1Taking a specific perspective as an example, the front end of the male connector 1 refers to the left end of the male connector 1. In this embodiment, the front end is based on... Figure 1 The orientations shown are described only for the purpose of illustrative purposes and are not intended to require the invention to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0033] by Figure 2 For example, the front end of the lock block body 31 is provided with two oppositely arranged connecting arms 30 to ensure the stability of the lock. Figure 10 For example, inward squeezing refers to squeezing the connecting arm 30 along the direction close to the axis of the anti-misoperation lock block 3.

[0034] The anti-accidental disconnection optoelectronic connector of the present invention achieves the anti-accidental disconnection function by adding an anti-accidental disconnection locking block 3 to restrict the downward movement of the elastic cantilever 100. Operation is simple, and the anti-accidental disconnection function is achieved by adding only one component, saving component costs. Furthermore, the anti-accidental disconnection locking block 3 is detachable; when the anti-accidental disconnection function is not required, this component can be removed to further reduce costs.

[0035] Combination Figure 2 To ensure overall structural stability and optimize component costs, in the preferred embodiment, the number of connecting arms 30 is set to two. When the connecting arm 30 is not deformed, the front side of the stop protrusion 301 on the connecting arm 30 abuts against the fixing member 101, preventing further forward pushing of the anti-mistaken removal locking block 3; that is, the anti-mistaken removal locking block 3 is in the first preset position. During the aforementioned process of snapping the male connector 1 onto the female connector 2, the connecting arm 30 undergoes elastic deformation due to the pressure from the inner wall of the female connector 2. The connecting arm 30 deforms, and the front side of the stop protrusion 301 no longer abuts against the fixing member 101, allowing the anti-mistaken removal locking block 3 to continue sliding forward until the unlocking protrusion 302 at the front end of the connecting arm 30 (e.g., ...) is reached. Figure 3 (As shown) Move to below the locking protrusion 104 of the elastic cantilever 100, so that the downward movement distance of the elastic cantilever 100 is reduced, and the pressable stroke of the elastic cantilever 100 is less than the unlocking stroke, so as to realize the function of preventing accidental removal.

[0036] In this embodiment, the anti-accidental removal lock block 3 is also detachably mounted on the male end tail sleeve 12. When the anti-accidental removal lock block 3 is not needed, it can be removed from the male end tail sleeve 12.

[0037] Continue reading Figure 2 and Figure 4A male end sleeve 12 is provided at the rear of the locking block body 31, and a limiting boss 105 is provided on the upper surface of the male end sleeve 12; a baffle 305 is provided below the locking block body 31, and the tail end of the baffle 305 abuts against the front side wall of the limiting boss 105 to fix the anti-mistake locking block 3 in the fixing groove 106.

[0038] The male connector 1 has a male tail sleeve 12 at its tail end. The upper surface of the male tail sleeve 12 has a limiting boss 105 to restrict the rearward movement of the anti-accidental removal locking block 3. The upper surface of the male tail sleeve 12 also has a strip-shaped boss 120, which is located on both sides of the limiting boss 105 to form a fixing groove 106. A baffle 305 is provided below the locking block body 31. The tail end of the baffle 305 abuts against the front side of the limiting boss 105 to fix the anti-accidental removal locking block 3 in the fixing groove 106.

[0039] The male end sleeve 12 is provided with a male end cable 121 at its tail end for transmitting optical signals and electrical signals. The male end sleeve 12 is used to buffer the cable when it is bent, so as to prevent the cable from being damaged by sharp bends.

[0040] Continue reading Figure 4 A baffle 305 is provided below the lock block body 31. The length of the baffle 305 is less than the length of the lock block body 31. The front end of the baffle 305 extends upward and is fixed together with the lower surface of the lock block body 31 to form an integral whole. There is a gap between the baffle 305 and the lock block body 31, so that the baffle 305 can undergo elastic deformation, which facilitates the installation and removal of the anti-accidental removal lock block 3.

[0041] In one embodiment, the baffle 305 is designed in an L-shape. When the anti-accidental removal lock block 3 is installed, the lock block body 31 slides forward from the limiting boss 105, and the lower surface of the baffle 305 abuts against the limiting boss 105. The limiting boss 105 lifts the baffle 305 upward to make it elastically deformed. When the anti-accidental removal lock block 3 is accommodated in the fixing groove 106, the baffle 305 and the limiting boss 105 no longer abut against each other, the elastic deformation of the baffle 305 is restored, and the anti-accidental removal lock block 3 is installed.

[0042] If the anti-accidental removal function is not required, the anti-accidental removal lock block 3 can be removed from the fixing groove 106. In one embodiment, when removing and installing the anti-accidental removal lock block 3, lift the tail end of the baffle 305 upward to make it elastically deform, pull the anti-accidental removal lock block 3 backward, and place the lower surface of the baffle 305 against the limiting boss 105. Continue to pull the anti-accidental removal lock block 3 backward, so that the baffle 305 continues to elastically deform until the anti-accidental removal lock block 3 is removed from the fixing groove 106.

[0043] See Figure 3The upper surface of the anti-accidental removal lock block 3 is provided with a stop platform 303. When the anti-accidental removal lock block 3 is pushed forward to realize the anti-accidental removal function, the stop platform 303 is used to limit the forward movement distance of the anti-accidental removal lock block 3. In actual use scenarios, the stop platform 303 can be rectangular, trapezoidal or triangular. In order to ensure uniform force and overall structural stability, in the preferred embodiment, the stop platform 303 is designed as a rectangle.

[0044] In high-density scenarios, to facilitate unlocking, the upper surface of the lock block body 31 is provided with a mark 304. In one embodiment, the mark 304 can be an "unlock arrow" to indicate the unlocking direction; the mark 304 can also be a "lock arrow" to indicate the locking direction.

[0045] As mentioned earlier, the anti-mistake-removal locking block 3 has a first preset position and a second preset position relative to the male connector 1. Before the male connector 1 is engaged with the female connector 2, the anti-mistake-removal locking block 3 is in the first preset position. After the male connector 1 is engaged with the female connector 2, because the connecting arm 30 is pressed inward by the female connector 2, if external force is continued to be applied to the anti-mistake-removal locking block 3, the anti-mistake-removal locking block 3 can continue to slide towards the female connector 2, thereby moving to the second preset position and achieving locking. The following mainly describes the relationship between the various structures when the anti-mistake-removal locking block 3 is in the first preset position and the second preset position relative to the male connector 1, in conjunction with specific structures.

[0046] See Figure 5 The connecting arm 30 is provided with a stop protrusion 301 on its outer side; the male end housing 10 is provided with at least one fixing member 101, the fixing member 101 is provided on the side of the elastic cantilever 100, and the fixing member 101 abuts against the stop protrusion 301 to restrict the anti-misoperation lock block 3 from moving forward.

[0047] At least one fixing member 101 is provided on the male end housing 10. The fixing member 101 is located on the side of the elastic cantilever 100 and corresponds one-to-one with the connecting arm 30. Before the male end connector 1 and the female end connector 2 are connected, in order to prevent the connecting arm 30 from sliding under the elastic cantilever 100 and causing the elastic cantilever 100 to be unable to press down, thereby preventing the male end connector 1 and the female end connector 2 from engaging, a stop protrusion 301 is provided on the outer side of the connecting arm 30. The front side (i.e., the stop surface) of the stop protrusion 301 abuts against the fixing member 101 to fix the position of the anti-mistake locking block 3. That is, the anti-mistake locking block 3 is in a first preset position relative to the male end connector 1.

[0048] It should be noted that the connection arm 30 is located below the elastic cantilever 100 when there is an overlapping area between the two in the horizontal projection. If there is no overlapping area between the two in the horizontal projection, even if the spatial relative positions are vertical, the connection arm 30 is not considered to be located below the elastic cantilever 100.

[0049] In practical applications, the contact surface of the stop protrusion 301 can be rectangular, circular, or triangular. To ensure uniform force distribution during contact, the contact surface of the stop protrusion 301 is set to a rectangle to avoid damage to the parts due to uneven force distribution during contact.

[0050] It should be noted here that, with Figure 5 Taking a specific perspective, the outer side of the connecting arm 30 refers to the side closer to the fixing member 101, and the inner side of the connecting arm 30 refers to the side farther from the fixing member 101. In this embodiment, the outer and inner sides are based on... Figure 5 The orientations shown are described only for the purpose of illustrative purposes and are not intended to require the invention to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention.

[0051] Combination Figure 3 and Figure 5 The connecting arm 30 has an unlocking protrusion 302 at its front end, which is located on the front side of the stop protrusion 301. The unlocking protrusion 302 abuts against the front side of the fixing member 101, that is, the anti-accidental removal locking block 3 is located in the first preset position to restrict the anti-accidental removal locking block 3 from moving backward.

[0052] The connecting arm 30 is provided with an unlocking protrusion 302 at its front end, which is located on the front side of the stop protrusion 301. The unlocking protrusion 302 is detachably abutted against the surface of the fixing member 101, which can restrict the anti-accidental removal lock block 3 from moving backward.

[0053] The unlocking protrusion 302 is provided at the front end of the connecting arm 30. The unlocking protrusion 302 protrudes from the outer surface of the connecting arm 30 and faces the outer side of the connecting arm 30. The distance between the outer surfaces of the unlocking protrusion 302 is greater than the distance between the inner surfaces of the fixing member 101.

[0054] In practical applications, the unlocking protrusion 302 can be trapezoidal, circular, or rectangular, etc. For ease of disassembly, the unlocking protrusion 302 is designed as a trapezoid. The front side of the unlocking protrusion 302 is beveled, matching the beveled opening at the tail end of the female connector 2, so that when the anti-mistaken removal locking block 3 is pushed forward, the unlocking protrusion 302 can slide into the interior of the female connector 2.

[0055] See Figure 6The inner surface of the fixing member 101 is provided with a stop groove 102 for accommodating the connecting arm 30, and the front end of the stop groove 102 is provided with a stop step 103 that abuts against the stop protrusion 301.

[0056] The fixing member 101 corresponds one-to-one with the connecting arm 30. The number of fixing members 101 is set to 2, which are symmetrically arranged about the elastic cantilever 100. The stop step 103 matches the stop protrusion 301. The outer side of the stop protrusion 301 slides forward against the inner side wall of the stop groove 102 until the stop surface of the stop protrusion 301 abuts against the rear side of the stop step 103 to restrict the movement of the anti-misoperation lock block 3 towards the front end of the outer shell 10.

[0057] To ensure that the anti-accidental removal lock block 3 is centered and does not shift, refer to... Figure 7 The upper surface of the male end housing 10 is provided with a sliding groove 107, which is used to accommodate the baffle 305. When installing and removing the anti-accidental removal lock block 3, the baffle 305 is aligned with the sliding groove 107 to facilitate determining the position of the anti-accidental removal lock block 3. The baffle 305 moves back and forth against the lower surface of the sliding groove 107 to avoid uneven force and damage to the parts.

[0058] See Figures 7-9 After locking the anti-misoperation locking block 3 in the first preset position, an external force is applied to the male connector 1 to engage the male connector 1 and the female connector 2. To ensure the stability of the engagement, the female connector 2 is provided with a female housing 20 at its tail end. The upper surface of the female housing 20 is provided with a first observation window 201. The elastic cantilever 100 is provided with locking protrusions 104 on both sides. The locking protrusions 104 engage in the groove formed by the protrusion below the first observation window 201.

[0059] Below the first observation window 201, there is a first protrusion 203 and a second protrusion 204 protruding from the female end housing 20. The locking protrusion 104 is engaged in the groove formed by the first protrusion 203 and the second protrusion 204. When the male end connector 1 and the female end connector 2 are mated, the engagement position of the locking protrusion 104 can be confirmed through the first observation window 201.

[0060] The first observation window 201 corresponds one-to-one with the locking protrusion 104. In actual use, the first observation window 201 can be rectangular, circular, or triangular, etc. In order to ensure the fixing effect, the first observation window 201 is set as rectangular. When the male connector 1 and the female connector 2 are connected, the elastic cantilever 100 is pressed down to push the male connector 1 forward. When the locking protrusion 104 is aligned with the bottom of the first observation window 201, the elastic cantilever 100 is released and the elastic cantilever 100 springs up, so that the locking protrusion 104 is engaged in the first observation window 201.

[0061] To limit the downward stroke of the elastic cantilever 100 and achieve the anti-accidental removal function, the locking protrusion 104 is engaged within the first observation window 201, and the anti-accidental removal locking block 3 is pushed forward to the second preset position. (See reference...) Figure 10 During the forward movement of the anti-accidental removal lock block 3, the unlocking protrusion 302 is squeezed by the inner wall of the female end shell 20, causing the connecting arm 30 to undergo elastic deformation. The stop protrusion 301 separates from the stop step 103, and the stop surface of the stop protrusion 301 no longer abuts against the rear side of the stop step 103, allowing the anti-accidental removal lock block 3 to continue moving forward.

[0062] See Figure 11 and Figure 12 The female end housing 20 has a locking window 200 coupled to the unlocking protrusion 302 on its side, and the locking window 200 is located to the side of the first observation window 201. During the process of the male end connector 1 engaging with the female end connector 2, at least one connecting arm 30 is pressed inward by the female end connector 2, and the anti-accidental removal locking block 3 can continue to slide towards the female end connector 2. The stop protrusion 301 passes over the stop step 103, so that the unlocking protrusion 302 slides below the locking protrusion 104 and is partially accommodated in the locking window 200 to fix the position of the anti-accidental removal locking block 3.

[0063] In this state, the unlocking protrusion 302 is accommodated in the locking window 200, and the rear side of the stop protrusion 301 abuts against the front side of the fixing member 101, that is, the anti-accidental removal lock block 3 is set in the second preset position.

[0064] In actual use, the anti-accidental removal lock block 3 continues to move forward, so that the unlocking protrusion 302 is accommodated in the locking window 200. The unlocking protrusion 302 is no longer squeezed by the inner wall of the female end shell 20. The connecting arm 30 restores its elastic deformation, and the stop protrusion 301 is set on the front side of the fixing member 101 and abuts against each other to restrict the anti-accidental removal lock block 3 from moving backward.

[0065] Combination Figure 11 When the anti-accidental removal lock block 3 is set in the second preset position, the unlocking protrusion 302 is pushed to below the locking protrusion 104. In one embodiment, the unlocking protrusion 302 partially falls below the locking protrusion 104 to limit the downward stroke of the elastic cantilever 100.

[0066] Continue reading Figure 12 The rear sides of the unlocking protrusion 302 and the stop protrusion 301 are set as slopes at a preset angle to facilitate unlocking the anti-mistaken removal lock block 3 from the second preset position.

[0067] To facilitate unlocking the anti-mistaken removal lock block 3, the rear sides of the unlocking protrusion 302 and the stop protrusion 301 are set as slopes. The slopes are set at a preset angle. In actual application scenarios, the angle between the slope and the longitudinal axis of the connector is set to 45°~60°, so that when the anti-mistaken removal lock block 3 is pulled backward, the locking relationship between the anti-mistaken removal lock block 3 and other components can be released.

[0068] Combination Figure 12 and Figure 13 If it is necessary to pull the male connector 1 out from the tail end of the female connector 2, it is only necessary to unlock the anti-mistaken removal locking block 3 from the second preset position. The front side apex angle of the fixing member 101 is defined as the first apex angle 109, and the rear side wall apex angle of the locking window 200 is defined as the second apex angle 205; the rear side of the stop protrusion 301 is defined as the first slope 306, and the rear side of the unlocking protrusion 302 is defined as the second slope 307.

[0069] Pull the anti-mistake lock block 3 horizontally backward, so that the first slope 306 slides backward against the first apex 109 and the second slope 307 slides backward against the second apex 205. The connecting arm 30 undergoes elastic deformation inward, and the unlocking protrusion 302 separates from the female end housing 2. Continue to pull the anti-mistake lock block 3 horizontally backward, so that it slides to the first preset position. The downward stroke of the elastic cantilever 100 is restored, the elastic cantilever 100 is unlocked, and the male end connector 1 is pulled out from the tail end of the female end connector 2.

[0070] Example 2: In order to achieve the coupling of optical signals and electrical signals, the male ferrule assembly 11 and the female ferrule assembly 21 are provided with electrical terminal mounting positions. The electrical terminals are detachably mounted around the optical contact to achieve electrical signal transmission.

[0071] Embodiment 2 of the present invention provides an optoelectronic hybrid connector, such as Figure 1 , Figures 14-15 As shown, the connector includes a male connector 1 and a female connector 2 mating at its front end. The male connector 1 has two male electrical terminals 14 arranged around a central axis, which are symmetrically distributed. The front end of each male electrical terminal 14 has at least two spring claws 140, which are set at a preset angle. The female connector 2 has two female electrical terminals 25 arranged symmetrically about a central axis. The rear end of each female electrical terminal 25 has a spring piece 250, which includes at least two planes 251 set at a preset angle. The male electrical terminals 14 and female electrical terminals 25 are one-to-one. When the connector is working, at least one spring claw 140 abuts against the plane 251 to transmit electrical signals.

[0072] This invention utilizes symmetrically arranged electrical terminals, with each contact distributed approximately circularly around the central optical axis. This ensures more balanced force on the optical coupling unit during coupling, preventing lateral forces on the central optical axis and improving fiber coupling efficiency and accuracy. Furthermore, the non-parallel structure of the electrical terminals enhances reliable and stable contact, improving coupling reliability under vibration. The male terminal employs a double-claw 140° layout with a specific angle, reducing terminal pressure and saving metal materials compared to the multiple spring-pin layouts used in conventional technologies. This optimizes space utilization and reduces component costs.

[0073] Combination Figure 14 In the figure, the dashed line AA is the central axis of the male connector 1. The two male electrical terminals 14 are symmetrically arranged about the central axis as the positive and negative poles for electrical signal transmission. The spring claw 140 at the front end of the male electrical terminal 14 is at a preset angle with the horizontal plane 251 to ensure the stability of electrical coupling. The preset angle is determined according to the actual application scenario.

[0074] Combination Figure 15 In the figure, the dashed line BB is the central axis of the female connector 2. The two female electrical terminals 25 are symmetrically arranged about the central axis, serving as the positive and negative poles for electrical signal transmission. After the male connector 1 and the female connector 2 are connected, the dashed line AA coincides with the dashed line BB and is located on the plane 251 to abut against the corresponding spring claw 140. The plane 251 and the spring claw 140 correspond one-to-one.

[0075] The contact point is the position where the spring claw 140 abuts against the plane 251. In one embodiment, in order to save material costs, the number of spring claws 140 is set to 2, the number of planes 251 is set to 2, and the number of contacts is 4. In a vibration scenario, the electrical terminals may vibrate in any direction. The spring claws 140 abut against the inner side of the plane 251. Since the spring claws 140 and the plane 251 are set as non-parallel structures, there is at least one contact point to realize electrical signal transmission.

[0076] A male end sleeve 12 is provided at the rear of the rear housing 13, and the male end sleeve 12 includes a male end cable 121; a female end sleeve 23 is provided in front of the female end electrical terminal 25, and the female end sleeve 23 includes a female end cable 24. In one embodiment, the male end cable 121 includes a male end optical cable and a male end electrical cable, and the female end cable 24 includes a female end optical cable and a female end electrical cable. If it is not necessary to transmit electrical signals, the electrical terminal and cable can be removed or the injection-molded electrical terminal can be eliminated during the overall injection molding process.

[0077] like Figures 14-16As shown, the male connector 1 includes a male ferrule assembly 11, and the male electrical terminals 14 are symmetrically arranged with respect to the male ferrule assembly 11; the female connector 2 includes an optical coupling alignment member 22, and the female electrical terminals 25 are symmetrically arranged with respect to the optical coupling alignment member 22; the male ferrule assembly 11 is provided with an elastic retainer 110, which is used to apply axial elastic force to the male ferrule assembly 11 and abut against the optical coupling alignment member 22.

[0078] The optical coupling alignment member 22 is provided with a female end ferrule assembly 21 on its front side, and the male end ferrule assembly 11 and the female end ferrule assembly 21 correspond one to one; the elastic retainer 110 is compressed and stores rebound force. Under the action of the rebound force, the male end ferrule assembly 11, the optical coupling alignment member 22, and the female end ferrule assembly 21 abut together in sequence to realize the coupling and transmission of optical signals.

[0079] To achieve optical coupling between the male connector 1 and the female connector 2, the male connector 1 is provided with a male ferrule assembly 11, the central axis of which is the central optical axis, which coincides with the central axis of the male connector 1. An elastic retainer 110 is arranged around the middle of the male ferrule assembly 11. After the male connector 1 and the female connector 2 are mated, the front end of the male ferrule assembly 11 and the tail end of the optical coupling alignment member 22 can always abut together through the elastic retainer 110. The tail end of the female ferrule assembly 21 and the front end of the optical coupling alignment member 22 also abut together under the action of elasticity to achieve coupling.

[0080] Specifically, see Figure 16 The male ferrule assembly 11 has an annular boss 111 in the middle. An elastic retainer 110 is disposed behind the annular boss 111 and surrounds the male ferrule assembly 11. The rear housing 13 has a rear housing opening 135 at its front end. A predetermined distance exists between the annular boss 111 and the rear housing opening 135 to form a mounting groove 130. The length of the mounting groove 130 is less than the axial length of the elastic retainer 110 when not under stress. The 0 is set in the mounting groove 130. When the rear housing 13 is engaged with the male housing 10, the rear side wall of the annular boss 111 presses the elastic retainer 110 backward, and the rear side wall of the rear housing opening 135 presses the elastic retainer 110 forward. The elastic retainer 110 is compressed and stores a rebound force. The rebound force pushes the male ferrule assembly 11 forward, so that the male ferrule assembly 11, the optical coupling alignment member 22 and the female optical alignment member are always in contact, realizing the coupling and transmission of optical signals.

[0081] like Figure 17 and Figure 18As shown, the male connector 1 further includes a male housing 10, which is disposed at the front end of the male ferrule assembly 11. The male housing 10 includes a housing body 15 and a sleeve 16 at its front end. At least one stop window 150 is provided on both sides of the housing body 15. The male ferrule assembly 11 is accommodated in the rear housing 13. At least one first snap-fit ​​platform 131 is provided on both sides of the rear housing 13. The stop window 150 is used to snap the first snap-fit ​​platform 131 to fix the housing body 15 and the rear housing 13.

[0082] The rear housing 13 has a first cable conduit 132 inside, which protrudes from the rear side of the rear housing 13. The tail end of the male ferrule assembly 11 is accommodated in the first cable conduit 132. Square grooves 133 are provided on both sides of the rear housing 13 for accommodating the tail end of the male electrical terminal 14. At least two first snap-fit ​​platforms 131 are provided on both sides of the square grooves 133 for fixing the rear housing 13 inside the outer housing body 15. A snap-fit ​​block 134 is provided behind the first snap-fit ​​platform 131 to limit the axial movement distance of the rear housing 13.

[0083] like Figure 18 As shown, in order to fix the male connector 1 and the female connector 2 together, at least one snap-fit ​​strip 108 is provided on the side of the male housing 10. In one embodiment, in order to ensure the overall stability of the structure, the snap-fit ​​strips 108 are symmetrically arranged about the elastic cantilever 100, with three on one side to ensure the fixing effect.

[0084] See Figure 19 The inner wall of the female connector 20 is provided with at least one first snap-fit ​​groove 202, which corresponds one-to-one with the snap-fit ​​strip 108. The front end of the first snap-fit ​​groove 202 is closed and the rear end is open, for accommodating the snap-fit ​​strip 108. When the male connector 1 and the female connector 2 are mated, the snap-fit ​​strip 108 is pushed forward from the open end of the first snap-fit ​​groove 202 until the front end of the snap-fit ​​strip 108 is in contact with the closed end of the first snap-fit ​​groove 202.

[0085] Continue reading Figure 18 and Figure 19 The upper surface of the female end housing 20 is provided with a locking window 200, and the elastic cantilever 100 is provided with locking protrusions 104 on both sides, and the locking protrusions 104 are engaged in the locking window 200.

[0086] The locking window 200 corresponds one-to-one with the locking protrusion 104. In actual use, the locking window 200 can be rectangular, circular, or triangular, etc. To ensure the fixing effect, the locking window 200 is set to a rectangle. When the male end socket is connected to the female end connector 2, press down on the elastic cantilever 100 to push the male end socket forward. When the locking protrusion 104 is aligned below the locking window 200, release the elastic cantilever 100. The elastic cantilever 100 springs up, so that the locking protrusion 104 is engaged in the locking window 200.

[0087] like Figure 20 As shown, in order to snap the rear housing 13 together with the outer shell body 15, at least two stop windows 150 are provided behind the snap-fit ​​strip 108. The stop windows 150 correspond one-to-one with the first snap-fit ​​platform 131 and are used to accommodate the first snap-fit ​​platform 131. The tail end of the outer shell body 15 is provided with a second snap-fit ​​groove 154. The second snap-fit ​​groove 154 is provided on the inner wall of the outer shell body 15 and corresponds one-to-one with the snap-fit ​​block 134. The second snap-fit ​​groove 154 is used to accommodate the snap-fit ​​block 134.

[0088] In one embodiment, the upper surface of the first locking platform 131 is set as a slope. The rear housing 13 is aligned with the tail end of the outer shell body 15, and the rear housing 13 is pushed forward horizontally. The inner wall of the rear housing 13 presses the first locking platform 131 inward, causing the first locking platform 131 to undergo elastic deformation. The inner wall of the rear housing 13 slides backward along the slope of the first locking platform 131, so that the rear housing 13 can continue to move forward until the rear side of the first locking platform 131 moves to the stop window 150. The first locking platform 131 restores its elastic deformation and locks into the stop window 150.

[0089] like Figure 21 As shown, a coupling support 151 is provided inside the main body 15 of the outer shell. The coupling support 151 has a first through hole 152 at its center for accommodating the front end of the male ferrule assembly 11. The coupling support 151 has first guide grooves 153 on both sides, and the male electrical terminal 14 can be inserted into the first guide groove 153 from the front end of the male outer shell 10. Alternatively, the male electrical terminal 14 and the male outer shell 10 are integrally injection molded by insert molding.

[0090] The first through hole 152 is used to accommodate the annular boss 111 at the front end of the male end ferrule assembly 11, so as to fix the male end ferrule assembly 11 on the coupling support 151. The tail end of the male end electrical terminal 14 is aligned with the front end of the first guide groove 153, and the male end electrical terminal 14 is pushed backward so that it is accommodated in the first guide groove 153. An arc-shaped protrusion 144 is provided on the inner surface of the male end electrical terminal 14. The inner wall of the front end of the first snap-fit ​​groove 202 is set as an arc-shaped opening, which fits against the arc-shaped protrusion 144.

[0091] In one embodiment, such as Figure 22 As shown, the male terminal 14 can be selected according to the actual use scenario. For example, the male terminal 14 can be inserted into the male housing 10, or it can be integrally injection molded with the male housing 10 or the rear housing 13 by insert molding.

[0092] like Figure 23 As shown, the female end housing 20 is provided with an inner sleeve 26 inside, and the inner sleeve 26 is provided with a second guide groove 207 for accommodating the female end electrical terminal 25. The female end electrical terminal 25 can be inserted into the second guide groove 207 from the front end of the female end housing 20; or, the female end electrical terminal 25 and the female end housing 20 are integrally injection molded by insert molding.

[0093] The inner sleeve 26 has a second through hole 206 at its center. The second through hole 206 is used to accommodate the female end ferrule assembly 21 so as to fix the female end ferrule assembly 21 on the inner sleeve 26. The spring piece 250 is aligned with the front end of the second guide groove 207 and pushed forward to be inserted into the second guide groove 207 so that the female end electrical terminal 25 is fixed in the second guide groove 207.

[0094] In one embodiment, the female terminal 25 can be selected according to the actual application scenario. For example, the female terminal 25 can be inserted into the female housing 20, or it can be integrally injection molded with the female housing 20 by insert molding.

[0095] like Figure 24 As shown, a first snap-fit ​​plate 142 is provided between the two spring claws 140 to fix it inside the outer shell body 15. The front end of the first snap-fit ​​plate 142 is provided with an abutment portion 141, the length of the front end of the abutment portion 141 being less than the length of the spring claw 140.

[0096] The front end of the male terminal 14 is a forked double spring claw 140, with the two spring claws 140 distributed at a certain angle; the width of the rear end of the terminal is greater than the width of the front spring claw 140. An abutment portion 141 is provided between the two spring claws 140, and the length of the front end of the abutment portion 141 does not exceed the length of the spring claw 140. During automated assembly, the abutment portion 141 can be clamped by an assembly jig to assemble the male terminal 14.

[0097] Combination Figure 24 The upper surface of the abutment portion 141 is provided with a limiting block 143. The upper surface of the limiting block 143 is set as a slope at a preset angle to limit the axial movement distance of the male terminal 14 in the first guide groove 153.

[0098] A limiting block 143 is provided at the front end of the arc-shaped protrusion 144. The height of the top of the limiting block 143 is the same as the height of the arc-shaped protrusion 144. When the male terminal 14 is pulled backward, the top of the limiting block 143 abuts against the arc-shaped opening, so that the male terminal 14 cannot move backward.

[0099] In one embodiment, see Figure 24 The spring claw 140 can be designed as a forward-extending spring claw.

[0100] In one embodiment, see Figure 25 The spring claw 140 can also be designed as a reverse-folding spring claw.

[0101] like Figure 26 As shown, the female terminal 25 includes a second snap-fit ​​plate 252 for fixing inside the female housing 20, and a connecting plate 253 extends perpendicularly to the direction of the second snap-fit ​​plate 252. The spring piece 250 is arranged perpendicular to the plane 251 of the connecting plate 253.

[0102] The two spring contacts 250 of the female terminal 25 are L-shaped with a preset angle, which is determined according to the actual application scenario. The two planes 251 of the L-shape are in contact with the two spring claws 140 of the male terminal 14, and the two spring contacts 250 are approximately symmetrically distributed around the central optical axis. After the female terminal 25 and the male terminal 14 are coupled, the positive force of the male spring contact 250 is evenly distributed on the central optical axis and cancels each other out, so the central optical axis will not wobble.

[0103] In one embodiment, when the product is in a vibrating environment, since the female terminal 25 and the male terminal 14 are distributed at a preset angle, the two contacts of the female terminal 25 and the male terminal 14 will not simultaneously lose contact, thus improving the stability of the electrical contact.

[0104] Example 3: To ensure the sealing effect of the coupling positions of the male terminal 14 and the female terminal 25, as well as the coupling positions of the male ferrule assembly 11 and the female ferrule assembly 21, Embodiment 3 of the present invention provides a high-sealing optoelectronic hybrid connector. (See attached document.) Figure 1 and Figure 27 The high-sealing optoelectronic hybrid connector includes a male connector 1, a female connector 2, and a sealing ring 4 disposed at the mating point of the male connector 1 and the female connector 2. The sealing ring 4 has elastic deformation capability. The male connector 1 has a male outer shell 10 at its front end, which includes an outer shell body 15 and a sleeve 16 disposed at the front end of the outer shell body 15. The female connector 2 has a female outer shell 20 at its rear end, which contains an inner sleeve 26. The inner sleeve 26 includes an inner sleeve body 260 and a coupling tube 261 at its rear end. The sealing ring 4 is disposed at the rear end of the inner sleeve body 260 and fits against the rear surface of the inner sleeve body 260. The sealing ring 4 wraps around the coupling tube 261 and the sleeve 16 to achieve sealing performance.

[0105] This invention avoids damage to the sealing ring 4 during operation by adding a built-in sealing ring 4 to the connector body. Compared with the sealing method of extruding the circular sealing ring 4 with an external sealing shell, it optimizes space utilization and is more suitable for high-density scenarios. The built-in sealing ring 4 is manufactured by one-piece molding, avoiding mold gaps, improving sealing performance and reliability. Moreover, the sealing ring 4 is easy to install and can be flexibly selected according to actual conditions.

[0106] After the male connector 1 and the female connector 2 are mated, the front end of the sleeve 16 presses against the sealing ring 4, as shown. Figure 27 As shown, the sealing ring 4 has a certain elastic deformation capacity. When squeezed, it can undergo radial elastic deformation, so that the outer surface of the sleeve 16 is tightly fitted with the sealing ring 4. At the same time, the sealing ring 4 wraps around the coupling tube 261 to achieve sealing performance and protect the optical coupling point and electrical coupling point from damage caused by external influences.

[0107] See Figure 28 and Figure 29 The sealing ring 4 has at least one thread 41 on at least one side surface to ensure that it can generate an effective compression amount when compressed by the sleeve 16; the female end outer shell 20 also includes a guide tube 27, and the inner sleeve body 260 is accommodated in the guide tube 27.

[0108] In one embodiment, if the elastic deformation capability of the sealing ring 4 is required to be small, the thread 41 on the sealing ring 4 can be set as a single thread; if the elastic deformation capability of the sealing ring 4 is required to be large, the thread 41 on the sealing ring 4 can be set as a continuous wavy thread.

[0109] In one embodiment, if the elastic deformation capability of the sealing ring 4 is less required, the thread 41 on the sealing ring 4 can be provided on one side of the inner ring or the outer ring; if the elastic deformation capability of the sealing ring 4 is more required, the thread 41 on the sealing ring 4 can be provided on both the inner ring and the outer ring.

[0110] In order to fix the inner sleeve 26 and the female end outer shell 20 together, the outer diameter of the inner sleeve body 260 is the same as the inner diameter of the guide tube 27, so that the outer side of the inner sleeve body 260 is tightly fitted with the inner sidewall of the guide tube 27 to fix them together.

[0111] See Figure 29 and Figure 30 The inner sleeve body 260 is provided with at least one stop protrusion 262 on its side. In order to ensure the fixing effect, the number of stop protrusions 262 is set to 2, which are arranged symmetrically on the top and bottom. The inner side wall of the guide tube 27 is also provided with a stop 263. The rear side of the stop protrusion 262 abuts against the front side of the stop 263 to limit the axial movement distance of the inner sleeve 26.

[0112] Continue reading Figure 30 The inner wall of the guide tube 27 is provided with a limiting step 270. There is a preset distance between the front side of the limiting step 270 and the rear side of the inner sleeve body 260 to form the sealing groove 40. The sealing groove 40 is used to accommodate the sealing ring 4.

[0113] A limiting step 270 is provided on the inner wall of the guide tube 27. There is a preset distance between the front side of the limiting step 270 and the rear side of the inner sleeve body 260 to form the sealing groove 40. The sealing groove 40 is used to accommodate the sealing ring 4. In this embodiment of the invention, the preset distance is the width of the sealing ring 4. The sealing ring 4 can be flexibly selected according to the actual situation, and the preset distance can be adjusted.

[0114] The diameter of the sleeve 16 is the same as the inner diameter of the limiting step 270, and the outer wall of the sleeve 16 abuts against the inner wall of the limiting step 270 to fix the sleeve 16 in the guide tube 27.

[0115] See Figures 31-33 The female connector 2 further includes a coupling support 29, which includes a support body 290 and a support post 291 disposed at its front end. To engage the coupling support 29 with the female housing 20, a snap-fit ​​seat 294 is disposed on the upper surface of the support body 290, and a second snap-fit ​​platform 295 is disposed on the surface of the snap-fit ​​seat 294. A sealing ring 28 (e.g., ...) is disposed at the front end of the female housing 20. Figure 27As shown), the sealing ring 28 includes two sealing platforms 280 arranged vertically. Two second observation windows 281 are provided on the sealing platform 280. The second observation window 281 corresponds one-to-one with the second snap-fit ​​platform 295, and the second snap-fit ​​platform 295 is coupled in the second observation window 281.

[0116] The inner wall of the sealing platform 280 is provided with a third protrusion 282 and a fourth protrusion 283. The third protrusion 282 is located on the front side of the second observation window 281, and the fourth protrusion 283 is located on the rear side of the second observation window 281 to form a locking groove 284, which is used to engage the second locking platform 295 to fix the coupling support 29 and the female end housing 20.

[0117] Combination Figure 31 and Figure 32 The female end housing 20 is provided with a sealing ring 28 at its front end, and the support base body 290 is disposed inside the sealing ring 28. The sealing ring 28 is provided with U-shaped openings on both sides. The female end electrical terminal 25 is disposed on both sides of the support base body 290, and its front end protrudes from the rear end of the U-shaped opening. The U-shaped opening is used to accommodate the electrical connector 240 at the front end of the female end cable. When the female end tail sleeve 23 includes the sealing ring 28, the electrical connector 240 can fit with the tail end of the second snap plate 252 to transmit electrical signals.

[0118] In one embodiment, the female terminal 25 can be selected according to the actual use scenario. For example, the female terminal 25 can be inserted into the inner sleeve 26, or it can be integrally injection molded with the inner sleeve 26 by insert molding. In this embodiment of the invention, the female terminal 25 is integrally injection molded with the inner sleeve 26 by insert molding.

[0119] Continue reading Figure 33 and Figure 34 The inner wall of the female end housing 20 is symmetrically provided with two first sliding grooves 265, one above the other. Each first sliding groove 265 corresponds to a stop boss 262 and is used to accommodate the stop boss 262. At least two positioning bosses 264 are symmetrically provided between the two stop bosses 262 to determine the connection position between the inner sleeve 26 and the female end housing 20. The inner wall of the female end housing 20 is also symmetrically provided with at least two second sliding grooves 266, one below the other. Each second sliding groove 266 corresponds to a positioning boss 264 and is used to accommodate the positioning boss 264.

[0120] In one embodiment, when it is necessary to fix the inner sleeve 26 and the female end outer shell 20, the stop boss 262 is aligned with the first slide groove 265 one by one, and the positioning boss 264 is aligned with the second slide groove 266 one by one. The inner sleeve 26 is pushed backward so that the inner sleeve 26 and the female end outer shell 20 are engaged together.

[0121] The inner sleeve 26 has a second through hole 206 at its center, which is used to accommodate the female end ferrule assembly 21. The inner sleeve body 260 has a snap-fit ​​post 267 on its front side to fix the female end ferrule assembly 21.

[0122] Combination Figure 33 and Figure 34 The inner sleeve 26 has a second through hole 206 at its center, which is used to accommodate the female ferrule assembly 21. The front side of the inner sleeve body 260 has two locking posts 267, which are symmetrically arranged vertically. To ensure structural stability, the locking posts 267 are located on the central axis of the connector. In a preferred embodiment, the locking posts 267 are designed to be semi-circular, with one side of their plane tangent to the second through hole 206 and abutting against the female ferrule assembly 21 to fix the female ferrule assembly 21 on the inner sleeve 26.

[0123] The outer surface of the female insert assembly 21 is provided with a second annular boss 212; the inner wall of the support post 291 protrudes from the inner wall of the support body 290, and there is a preset distance between the front side of the snap-fit ​​post 267 and the rear side of the support post 291 to form an annular groove 268 for accommodating the second annular boss 212.

[0124] See Figure 35 The female ferrule assembly includes a ferrule tube 210 and a ferrule 211 housed therein. The front end of the ferrule tube 210 is provided with a second annular boss 212. The tail end of the ferrule 211 is housed in an optical coupling alignment member 22. The front end of the ferrule tube 210 is housed in a support post 291. The inner wall of the support post 291 protrudes from the inner wall of the support body 290. The snap-fit ​​post 267 is located behind the support body 290. There is a preset distance between the front side of the snap-fit ​​post 267 and the rear side of the support post 291 to form an annular groove 268. The annular groove 268 is used to accommodate the second annular boss 212 to limit the axial movement distance of the female ferrule assembly.

[0125] The inner sleeve body 260 is provided with a sealing groove 40 on the rear side for accommodating the sealing ring 4. The sealing ring 4 is capable of elastic deformation. In one embodiment, the width of the sealing ring 4 is greater than or equal to the width of the sealing groove 40. When the sealing ring 4 is placed into the sealing groove 40, the front and rear side walls of the sealing groove 40 compress the sealing ring 4, so that the sealing ring 4 is compressed and stores elastic force to fix it in the sealing groove 40.

[0126] The inner sleeve body 260 is provided with a coupling support seat 29 at its front end. The coupling support seat 29 includes a support seat body 290 and a support column 291. The upper and lower surfaces of the support seat body 290 are each provided with two snap-fit ​​seats 294. The two snap-fit ​​seats 294 are spaced apart by a preset distance to form a third guide groove 296. The front surface of the inner sleeve body 260 is provided with two third snap-fit ​​plates 269. The third snap-fit ​​plates 269 are snapped into the third guide groove 296 to fix the inner sleeve body 260 and the coupling support seat 29 together.

[0127] See Figure 36 The support body 290 has at least one locking seat 294 on its upper and lower surfaces. To ensure overall structural stability, in a preferred embodiment, each surface has two locking seats 294, and each locking seat 294 corresponds one-to-one with the second observation window 281. The upper surface of each locking seat 294 has a second locking platform 295. In practical applications, the second locking platform 295 can be trapezoidal or triangular. To ensure a secure hold, in a preferred embodiment, the second locking platform 295 is designed as a trapezoid and is accommodated within the locking groove 284.

[0128] In one embodiment, when fixing the support body 290 and the female outer casing 20, the tail end of the snap-fit ​​seat 294 is aligned with the front end of the sealing ring 28, so that the upper surface of the snap-fit ​​seat 294 is in contact with the lower surface of the third protrusion 282. The support body 290 is then pushed horizontally backward until the inclined edge of the second snap-fit ​​platform 295 abuts against the front end of the third protrusion 282. The support body 290 is then pushed horizontally backward, and the second snap-fit ​​platform 295 undergoes elastic deformation under compression. Block 282 slides on the inclined side, continuously pressing the second locking platform 295. The movement position of the second locking platform 295 can be confirmed through the second observation window 281. When the second locking platform 295 is fully accommodated in the locking groove 284, the second locking platform 295 is no longer compressed and restores its elastic deformation. The right-angled side of the second locking platform 295 abuts against the front side wall of the locking groove 284, and the rear side of the coupling body abuts against the front side of the inner sleeve 26 to limit the axial movement distance of the support body 290.

[0129] Continue reading Figure 36 and Figure 37To fix the support body 290 and the inner sleeve 26, the two snap-fit ​​seats 294 are spaced apart by a preset distance to form a third guide groove 296. Two third snap-fit ​​plates 269 are provided on the front surface of the inner sleeve body 260. The two third snap-fit ​​plates 269 are arranged symmetrically above and below, and their width is the same as the width of the third guide groove 296. Two snap-fit ​​posts 267 are provided between the two third snap-fit ​​plates 269. In order to ensure structural stability, the third snap-fit ​​plates 269 and the two snap-fit ​​posts 267 are all located on the central axis of the connector.

[0130] In one embodiment, when the coupling seat body 290 is pushed backward, the third snap-fit ​​plate 269 is attached to the inner wall of the third guide groove 296 on both sides, the third snap-fit ​​plate 269 is accommodated in the third guide groove 296, and the snap-fit ​​post 267 is accommodated inside the support seat body 290.

[0131] In one embodiment, combined Figure 36 The coupling seat body 290 has coupling grooves 297 on both outer surfaces. The coupling grooves 297 are used to partially accommodate the second snap-fit ​​plate 252, so that the second snap-fit ​​plate 252 can contact the electrical connector 240 to achieve electrical coupling.

[0132] See Figure 38 The female end outer casing 20 is provided with a sealing ring 28 at its front end. The female end tail sleeve 23 is formed by insert molding, so that the height of the inner cavity of the female end tail sleeve 23 is equal to the distance between the upper and lower outer surfaces of the sealing ring 28, and the width of the inner cavity of the female end tail sleeve 23 is equal to the distance between the two outer surfaces of the sealing ring 28. The inner surface of the female end tail sleeve 23 and the outer surface of the sealing ring 28 can fit tightly together to fix them together.

[0133] Combination Figure 35 and Figure 38 To ensure that the female cable 24 is not squeezed in the female end sleeve 23, a second cable conduit 292 is provided inside the support column 291 to accommodate the female cable 24. This conduit acts as a buffer when the female cable 24 bends, preventing the cable from being damaged by sharp bends.

[0134] The outer surface of the support post 291 is uniformly provided with a fish scale pattern; the female connector 2 also includes a pressure ring 293, the axial cross section of the pressure ring 293 is "Y" shaped, and the inner wall of the tail end of the pressure ring 293 is provided with a thread. In one embodiment, the support post 291 is inserted from the tail end of the pressure ring 293, the thread is wavy, and radial pressure is applied to the pressure ring 293 by using ring tweezers, so that the thread is locked with the fish scale pattern, and the pressure ring 293 is fixed together with the support post 291.

[0135] The sealing ring 4 is fixed in the sealing groove 40 by the triaxial compression of the rear side wall of the inner sleeve body 260, the inner wall of the guide tube 27, and the front side wall of the limiting step 270. When the male connector 1 and the female connector 2 are mated, the sealing ring 4 is also compressed by the outer wall of the sleeve 16. The sealing ring 4 generates radial elastic deformation and stores rebound force, wrapping the sleeve 16 and the coupling tube 261 inside to achieve sealing performance.

[0136] Example 4: Embodiment 2 of the present invention provides a method for using an optoelectronic hybrid connector, such as... Figure 38 As shown, the optoelectronic hybrid connector applicable to Embodiment 1 includes: In step 101, the male terminal 14 is snapped into the interior of the housing body 15, and the female terminal 25 is also snapped into the interior of the female housing 20.

[0137] Align the tail end of the first snap-fit ​​plate 142 with the front end of the first guide groove 153, push the first snap-fit ​​plate 142 backward so that it is accommodated in the first guide groove 153, continue to push the first snap-fit ​​plate 142 backward so that the arc-shaped protrusion 144 is accommodated in the square groove 133 until the arc-shaped opening is in contact with the arc-shaped protrusion 144; align the spring piece 250 with the front end of the second guide groove 207, push it forward and insert it into the second guide groove 207 so that the female terminal 25 is fixed in the second guide groove 207.

[0138] In step 102, the front end of the male connector 1 and the tail end of the female connector 2 are aligned, and the male connector 1 is pushed forward horizontally to snap the male connector 1 and the female connector 2 together to achieve optical signal coupling.

[0139] Pressing down on the elastic cantilever 100 pushes the male socket forward. The rear wall of the mounting groove 130 presses forward against the elastic retainer 110. The elastic retainer 110 is compressed and stores a rebound force. This rebound force pushes the male ferrule assembly 11 forward, ensuring that the male ferrule assembly 11, the optical coupling alignment member 22, and the female optical alignment member are always in contact, achieving optical signal coupling and transmission. Continuing to push the male socket forward, when the locking protrusion 104 is aligned below the locking window 200, the elastic cantilever 100 is released. The elastic cantilever 100 springs upward, causing the locking protrusion 104 to engage within the locking window 200.

[0140] In step 103, the male connector 1 and the female connector 2 are mated together, so that the male electrical terminal 14 and the female electrical terminal 25 abut together, that is, the spring claw 140 abuts against the inner surface of the spring piece 250, thereby achieving electrical terminal coupling.

[0141] The two planes 251 of the female terminal 25 are in contact with the two spring claws 140 of the male terminal 14 respectively. After the female terminal 25 and the male terminal 14 are coupled, the positive force of the male spring 250 is evenly distributed on the central optical axis and cancels each other out. The central optical axis will not be deflected. In the vibration scenario, there is at least one contact point to realize the transmission of electrical signals.

[0142] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
