Description

Technical Field

[0001] This application relates to the field of laser technology, and in particular to optical module testing fixtures. Background Technology

[0002] Fiber lasers are lasers that use rare-earth-doped glass fibers as the gain medium. They have found wide applications in industrial manufacturing, medical fields, and military defense. Fiber lasers can be developed based on fiber amplifiers. Under the action of pump light, high power density can easily be formed within the fiber, causing population inversion of the laser energy levels in the laser gain medium. By appropriately adding a positive feedback loop, laser oscillation output can be generated. They are now widely used in industrial processing, such as cutting and welding.

[0003] In the manufacturing process of lasers, they are generally first assembled into optical modules. Then, the optical modules are powered on by optical module testing fixtures to check whether the relevant parameters of the optical modules meet the standards. Only optical modules that meet the standards are then assembled.

[0004] However, existing optical module testing fixtures require connecting the optical module's terminals to the power cord using screws, which is cumbersome and affects the testing efficiency of the optical module. Utility Model Content

Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0035] This application provides an optical module testing fixture. The following provides a detailed description of each embodiment of the optical module testing fixture.

[0036] Figure 1 This is a schematic diagram of one embodiment of the optical module testing fixture provided in this application. Figure 1 As shown, the optical module testing fixture 100 includes a support 110 and a conductive structure 120. The conductive structure 120 is mounted on the support 110 and is used to electrically connect to a power supply. The conductive structure 120 is also used to electrically connect to the wiring terminals of the optical module, so that the power supply supplies power to the optical module through the conductive structure 120, enabling the optical module to operate and facilitating the detection of whether the relevant parameters of the optical module meet the standards.

[0037] like Figure 1 and Figure 2 As shown, the support member 110 includes a support surface 111 located on one side of the support member 110 along the first direction X. The conductive structure 120 includes at least two conductive elements 121 connected to the support member 110. The conductive elements 121 are used for electrical connection with a power source and for electrical connection with the wiring terminals of the optical module, thereby connecting the power source to the optical module.

[0038] The number of conductive elements 121 can be even, with each pair of conductive elements 121 used for electrical connection to the two terminals of an optical module with opposite polarities. The number of conductive elements 121 can be 2, 4, 6, etc. The more conductive elements 121 there are, the more the conductive structure 120 of the optical module test fixture 100 can simultaneously connect the power supply to multiple optical modules.

[0039] In some embodiments, the conductive member 121 may include a conductive post 1211 protruding from the support surface 111, the conductive post 1211 extending along the first direction X, the conductive post 1211 being used to insert into the wiring terminals of the optical module and electrically connect with the wiring terminals of the tube module. The optical module testing fixture 100 also includes an abutment member 130, the abutment member 130 being located on one side of the support member 110 along the first direction X, and the abutment member 130 being movable relative to the support member 110 between an abutment position and a disengagement position. When the abutment member 130 is in the abutment position (e.g., ...), Figure 1 When the contact member 130 is in the separated position, it abuts against the terminal block on one side along the first direction X, thereby maintaining stable contact between the terminal block of the optical module and the conductive post 1211, improving the conductivity stability between the power supply and the optical module. When the contact member 130 is in the separated position, the contact member 130 is separated from the terminal block of the optical module, and there is a gap between the contact member 130 and the conductive post 1211 for the terminal block of the optical module to pass through, so as to remove the terminal block of the optical module from the conductive post 1211, or to sleeve the terminal block of the optical module onto the conductive post 1211.

[0040] The optical module testing fixture 100 provided in this application embodiment allows the conductive post 1211 of the conductive member 121 to protrude from the conductive post 1211 of the support surface 111 and extend along the first direction X, and allows the abutment member 130 to be between the abutment position and the separation position relative to the support member 110, so that the wiring terminals of the optical module can be stably electrically connected to the conductive post 1211, and the wiring terminals of the optical module can also be easily sleeved on or removed from the conductive post 1211, which is very convenient to operate and helps to improve the testing efficiency of the optical module.

[0041] In some embodiments, as Figure 1 and Figure 2 As shown, a clearance hole 131 can be provided in the abutment member 130. When the abutment member 130 is in the abutment position, the conductive post 1211 is at least partially inserted into the clearance hole 131. Thus, when the abutment member 130 abuts against the wiring terminal of the optical module on one side of the first direction X, the part of the abutment member 130 extending out of the wiring terminal on the side of the first direction X will not interfere with the wiring terminal.

[0042] The number of clearance holes 131 can be the same as the number of conductive posts 1211, and they correspond one-to-one. When the abutment member 130 is in the abutment position, at least part of the multiple conductive posts 1211 are inserted into the multiple clearance holes 131 in a one-to-one correspondence.

[0043] In some embodiments, at least two conductive elements 121 of the conductive structure 120 may be sequentially distributed along the second direction Y, wherein the second direction Y is substantially perpendicular to the first direction X, so that the conductive posts 1211 of at least two conductive elements 121 of the conductive structure 120 can be connected to the wiring terminals of the optical module.

[0044] The conductive post 1211 of the conductive element 121 can pass through the support member 110. The conductive element 121 also includes a terminal post 1213, one end of which is connected to the end of the conductive post 1211 away from the abutment member 130, and the terminal post 1213 extends along the third direction Z. The first direction X, the second direction Y, and the third direction Z are substantially perpendicular to each other, thereby making it easier to connect the terminal post 1213 to the power supply.

[0045] The conductive post 1211 and the terminal post 1213 can be made of the same or different materials, as long as they are conductive. Alternatively, the terminal post 1213 and the conductive post 1211 can be an integral or separate structure, as long as they are electrically connected.

[0046] Specifically, the support member 110 is plate-shaped. The support surface 111 of the support member 110 is the plate surface on one side of the support member 110 in the thickness direction. The support surface 111 of the support member 110 is substantially perpendicular to the first direction X. The conductive post 1211 of the conductive member 121 passes through the support member 110 along the first direction X. The two ends of the conductive post 1211 are located on both sides of the support member 110.

[0047] In some embodiments, as Figure 1 and Figure 2 As shown, the optical module testing fixture 100 also includes a first support plate 140 and two second support plates 150. The first support plate 140 is basically perpendicular to the third direction Z. The first support plate 140 is connected to the support member 110 on the side opposite to the third direction Z. The two second support plates 150 are connected to the support member 110 on both sides along the second direction Y, and the two second support plates 150 are respectively basically perpendicular to the second direction Y.

[0048] By providing second support plates 150 on both sides of the support member 110 along the second direction Y, and providing a first support plate 140 on the side of the support member 110 along the third direction Z in the opposite direction, the support member 110 can be stably supported, making the position of the support member 110 more stable.

[0049] The terminal 1213 can be extended from the support member 110 on the Z-direction side to facilitate electrical connection between the terminal 1213 and the power supply line.

[0050] In other embodiments, such as Figure 3 and Figure 4 As shown, a wiring hole 141 extending in a third direction Z can also be provided in the first support plate 140, and the terminal 1213 can extend from the conductive post 1211 toward the first support plate 140. Thus, the power cord can pass through the wiring hole 141 and be electrically connected to the terminal 1213 of the conductive member 121.

[0051] In some embodiments, the optical module testing fixture 100 may further include a base plate 160, which is located on the side of the support member 110 opposite to the first direction X, and the base plate 160 is connected to the first support plate 140 and two second support plates 150, thereby making the structure of the optical module testing fixture 100 more stable. A cavity is formed between the support member 110 and the base plate 160, and the terminal block 1213 is located within the cavity between the support member 110 and the base plate 160.

[0052] In some embodiments, the first support plate 140 and the second support plate 150 are made of insulating material to improve the safety performance of the optical module testing fixture 100. Alternatively, the base plate 160 may also be made of insulating material.

[0053] In some embodiments, as Figure 1 and Figure 2 As shown, the abutment 130 can be slidably connected to the support 110 along the first direction X, allowing the abutment 130 to slide relative to the support 110 between an abutment position and a disengaged position. Specifically, when the abutment 130 slides toward the support 110 to abut against the terminal sleeved on the conductive post 1211, the abutment 130 is in the abutment position. When the abutment 130 slides away from the support 110 to a position disengaged from the terminal, and the gap between the abutment 130 and the conductive post 1211 allows the terminal to be removed from the conductive post 1211, the abutment 130 is in the disengaged position.

[0054] The abutment 130 includes an abutment surface opposite to the support surface 111 of the support member 110. One of the support surface 111 and the abutment surface of the support member 110 is provided with a guide post 112 extending along the first direction X. The other of the support surface 111 and the abutment surface is provided with a guide hole 132 extending along the first direction X. The guide post 112 is slidably installed in the guide hole 132 along the first direction X so that the abutment 130 is stably slidably connected to the support member 110 along the first direction X.

[0055] It is understood that a guide post 112 extending in the first direction X can be protruded from the support surface 111 of the support member 110, and a guide hole 132 extending in the first direction X can be formed on the abutment surface of the abutment member 130 at a position corresponding to the guide post 112. Alternatively, a guide post 112 extending in the first direction X can be protruded from the abutment surface of the abutment member 130, and a guide hole 132 extending in the first direction X can be formed on the support surface 111 of the support member 110 at a position corresponding to the guide post 112.

[0056] In this design, at least two conductive elements 121 of the conductive structure 120 are sequentially distributed along a second direction Y, which is substantially perpendicular to the first direction X. Simultaneously, there are multiple guide posts 112 distributed at both ends of the support member 110 along the second direction Y. Correspondingly, there are multiple guide holes 132, the number of which is equal to the number of guide posts 112, and they correspond one-to-one. By sliding the multiple guide posts 112 one-to-one with the multiple guide holes 132, the sliding connection stability between the abutment member 130 and the support member 110 can be further improved.

[0057] In some embodiments, as Figure 1 and Figure 2 As shown, the optical module testing fixture 100 may also include a pressing mechanism 170. When the abutting member 130 is in the abutting position, the pressing mechanism 170 abuts against the abutting member 130 on one side along the first direction X, thereby increasing the abutting force applied by the abutting member 130 to the terminal block and making the connection between the terminal block and the conductive post 1211 more stable.

[0058] The pressing mechanism 170 can be multiple, and each pressing mechanism 170 is used to abut against the abutment member 130 on one side along the first direction X, so as to further increase the abutment force applied by the abutment member 130 to the terminal. Specifically, there are two pressing mechanisms 170, which are respectively connected to the side of the first support plate 140 away from the support member 110, and the two pressing mechanisms 170 are distributed sequentially along the second direction Y.

[0059] In some embodiments, the pressing mechanism 170 can be an elbow clamp. The pressing mechanism 170 includes a first handle 171, a first linkage structure 172, and a pressing member 173. The first handle 171 is connected to the pressing member 173 via the first linkage structure 172. The pressing member 173 includes a pressing portion 1731 for abutting against one side of the abutment member 130 along the first direction X. The first handle 171 is rotatable relative to the support member 110, thereby driving the pressing member 173 to move via the first linkage structure 172, causing the pressing portion 1731 of the pressing member 173 to displace in the first direction X, thus causing the pressing portion 1731 to abut against or separate from the abutment member 130 along the first direction X.

[0060] In other embodiments, such as Figure 3 and Figure 4 As shown, the optical module testing fixture 100 may further include a drive mechanism 180, which is connected to the abutment member 130 and is used to drive the abutment member 130 to move between an abutment position and a separation position. The operator can more conveniently drive the abutment member 130 between the abutment position and the separation position using the drive mechanism 180.

[0061] The drive mechanism 180 may include a second handle 181, a second linkage structure 182, and a connector 183. The second handle 181 is connected to the connector 183 through the second linkage structure 182, and the connector 183 is connected to the pressing member 173. The second handle 181 can rotate relative to the support member 110 to drive the connector 183 to move along the first direction X through the second linkage, so that the connector 183 drives the pressing member 173 to move along the first direction X.

[0062] In some embodiments, the outer periphery of the conductive post 1211 is provided with an abutment portion 1212, which is used to abut against the side of the wiring terminal opposite to the first direction X. By providing the abutment portion 1212 on the outer periphery of the conductive post 1211, when the abutment member 130 abuts against the side of the wiring terminal of the optical module along the first direction X, the wiring terminal can be stably contacted with the abutment portion 1212, which is beneficial to improving the conductivity between the wiring terminal and the conductive post 1211.

[0063] The contact portion 1212 can extend circumferentially along the conductive post 1211 in a ring structure to further increase the contact area between the contact portion 1212 and the terminal, thereby improving the conductivity between the conductive post 1211 and the terminal.

[0064] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
