Description

Technical Field

[0001] The invention relates to a photoelectric device testing material box and photoelectric device testing equipment, belonging to the technical field of photoelectric device testing. Background Art

[0002] Optoelectronic devices are widely used in the fields of communication, imaging, measurement, etc., such as photodetectors and electro-optic modulators. Photodetectors are devices that can convert optical signals into electrical signals. Electro-optic modulators are devices that control optical signals through electrical signals based on the electro-optic effect to achieve transmission and processing of optical signals. In the production process of optoelectronic devices, the performance of optoelectronic devices needs to be tested to ensure their factory quality. At present, some optoelectronic device modules have optical fibers integrated inside and optical fiber extensions, such as Figure 1 The figure shows an electro-optic modulator in the prior art. The electro-optic modulator 100 is connected to an optical fiber 101. There is only one optical fiber 101 and it is connected from one side of the electro-optic modulator 100. A signal interface 102 is also provided on the side, and a power interface 103 is provided on the other side opposite to the side. Figure 2 Another electro-optic modulator in the prior art is shown. The electro-optic modulator 200 is connected to an optical fiber 201. There are two optical fibers 201 that extend from two sides of the electro-optic modulator 200. A signal interface 202 and a power interface 203 are provided on the other two sides of the electro-optic modulator 200.

[0003] At present, the optical fiber extension of optoelectronic devices is relatively long. Although the optical fiber has good flexibility, it may break if it is not handled properly. In addition, the movement of the optical fiber during the test is uncontrollable, which can easily interfere with other test equipment and the test process, affecting the smooth progress of the test process. Therefore, it is very necessary to pre-process the optoelectronic devices before the test begins and store the extended optical fiber.

[0004] The existing wire collection box is mainly used to store and wind cables. For example, a lead wire storage box disclosed in the Chinese utility model patent with the authorization announcement number CN220364190U includes a box body and a box cover. The box cover is provided with a round hole, a rotating disk is rotatably installed in the round hole, a connecting disk is installed on the lower end surface of the rotating disk, a wire clamping groove is provided on the connecting disk, and arc grooves are respectively provided in the radial direction of the mating surfaces of the box body and the box cover to form a through hole after mating. When in use, the middle part of the lead wire is clamped on the wire clamping groove, and the lead wire passes through the through holes on both sides. The rotating disk is rotated to drive the connecting disk to rotate, and the lead wire can be wound into the cavity between the connecting disk and the box cover.

[0005] The above-mentioned lead wire storage box cannot be used for the optoelectronic device to be tested because the signal interface and power interface of the optoelectronic device cannot be exposed, and thus the interface cannot be plugged into the detection device for testing operations. Even if an exposure opening is opened on the box cover, it cannot be used because the interface and the optical fiber are in the same plane. After the optical fiber is wound, the interface will inevitably be blocked and it cannot be plugged into the detection device. Therefore, the optical fiber must not only be able to be wound, but also avoid the interface. This is a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0006] The object of the present invention is to provide a photoelectric device testing material box to solve the problem that there is no material box suitable for photoelectric device testing in the prior art, which leads to the risk of optical fiber breakage during the testing process and easily interferes with other testing equipment and testing processes, thereby affecting the smooth progress of the testing process; the object of the present invention is also to provide a photoelectric device testing equipment to solve the above problems.

[0007] To achieve the above purpose, the optoelectronic device test kit of the present invention adopts the following technical solution: A photoelectric device testing material box comprises a base and a box body rotatable relative to the base, a placement groove for placing the photoelectric device is arranged on the box body, an exposure port penetrating the groove side wall to expose the interface of the photoelectric device and a threading port for the optical fiber of the photoelectric device to pass through are arranged on the groove side wall of the placement groove, an annular cavity connected with the threading port is formed between the base and the box body, the annular cavity is located below the exposure port, a hook is movably installed on the base and an elastic member is arranged between the base and the hook, the hook portion of the hook has an initial position corresponding to the position of the threading port for the optical fiber to enter the hook portion, and also has a hooking position that is pressed by the box body to move into the annular cavity after the box body and the base rotate relative to each other so as to hook the optical fiber into and wrap it in the annular cavity, and the elastic member is deformed by force during the movement of the hook portion to the hooking position.

[0008] The beneficial effects of the above technical scheme are as follows: the present invention is a pioneering invention, which provides a photoelectric device test box, which includes a base and a box body, a placement groove on the box body can accommodate the photoelectric device, and the exposure opening on the groove side wall of the placement groove can expose the interface of the photoelectric device so that the interface can be plugged into the detection device and then perform the test operation; the threading opening on the groove side wall can allow the optical fiber of the photoelectric device to pass through; in addition, an annular cavity connected to the threading opening is formed between the base and the box body, and a hook is movably installed on the base and an elastic member is arranged between the base and the hook, the hook portion of the hook has an initial position corresponding to the position of the threading opening for the optical fiber to enter the hook portion, and also has a hooking position that is pressed by the box body to move into the annular cavity after the box body and the base rotate relative to each other so as to hook the optical fiber into and wrap it around the annular cavity.

At this time, the optical fiber is hooked into the annular cavity, and as the base and the box body continue to rotate relative to each other, the optical fiber will be wound in the annular cavity to realize the storage of the extended optical fiber. At the same time, since the annular cavity is located below the exposure port, the stored optical fiber will not block the interface, thereby ensuring that the interface can be normally exposed for plugging with the detection device.

In addition, the elastic member is deformed by force during the movement of the hook. After the test is completed, the hook can be reset under the force of the elastic member through the reverse relative rotation of the base and the box body, which is convenient for repeated use.

DETAILED DESCRIPTION

[0031] In view of the technical problems existing in the prior art, the basic concept of the present invention is to provide a material box that can be used for testing optoelectronic devices, which can expose the interface of the optoelectronic device, and a hook is movably installed on the material box. The hook is forced to move through the relative rotation of the box body and the base, so as to hook the optical fiber into and wind it in the ring cavity, thereby avoiding the extension of the optical fiber and preventing the optical fiber from blocking the interface of the optoelectronic device during the winding process, thereby ensuring smooth testing.

[0032] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0033] Embodiment 1 of the photoelectric device test kit of the present invention: like Figure 3 and Figure 4 As shown, the photoelectric device test material box includes a base 1 and a box body 2 that can rotate relative to the base 1. The outer peripheral surfaces of the base 1 and the box body 2 are both cylindrical surfaces, and the outer diameters of the two are equal. The box body 2 is provided with a placement groove 2-1 for placing the photoelectric device. The placement groove 2-1 is arranged in the center relative to the box body 2. The placement groove 2-1 in this embodiment is used to place Figure 1 The electro-optic modulator 100 shown in FIG. 1 is a rectangular parallelepiped structure, so the placement slot 2-1 is a rectangular slot. Figure 5As shown, the placement slot 2-1 has four slot side walls and a slot bottom wall, one of the slot side walls is provided with a power interface exposure opening 2-2 that penetrates the slot side wall and is used to expose the power interface 103 of the electro-optic modulator 100, and the other opposite slot side wall is provided with a signal interface exposure opening 2-3 that penetrates the slot side wall and is used to expose the signal interface 102 of the electro-optic modulator 100. In fact, the size of the placement slot 2-1 is adapted to the main body size of the electro-optic modulator 100, and the horizontal movement of the electro-optic modulator 100 can be restricted after it is placed, so the power interface 103 extends into the power interface exposure opening 2-2, and the signal interface 102 extends into the signal interface exposure opening 2-3. A threading opening 2-4 for the optical fiber 101 of the power optical modulator 100 to pass through is also provided on the slot side wall on the same side as the signal interface exposure opening 2-3. Since the electro-optic modulator 100 has only one side for wire outlet, only one threading opening 2-4 is provided.

[0034] like Figure 4 and Figure 8 As shown, a ring cavity 5 connected to the threading port 2-4 is formed between the base 1 and the box body 2, and the ring cavity 5 is located below the power interface exposure port 2-2 and the signal interface exposure port 2-3. Figure 6 As shown, an annular groove 2-5 is provided on the back side of the box body 2 (i.e., the side facing away from the placement groove 2-1, i.e., the bottom side of the box body 2, and also the end side of the box body 2 facing the base 1). The annular groove 2-5 and the base 1 together form the above-mentioned annular cavity 5. The annular groove 2-5 is located at the edge of the box body 2 and is concentric with the box body 2. The annular groove 2-5 has a circumferential inner groove wall and a circumferential outer groove wall that are concentrically and spaced apart.

[0035] like Figure 7 and Figure 8 As shown, an annular convex edge 1-4 is provided on the base 1, and the annular convex edge 1-4 is located at the edge of the base 1 and is concentric with the base 1. When the base 1 and the box body 2 are assembled, the annular convex edge 1-4 extends into the annular groove 2-5 and contacts and slides with the inner wall of the circumference, thereby realizing the positioning between the base 1 and the box body 2 and facilitating the relative rotation between the two.

[0036] like Figure 3 , Figure 4 and Figure 7 As shown, a hook 3 is movably mounted on the base 1 and an elastic member is provided between the base 1 and the hook 3. Under the action of the elastic member, the hook portion 3-2 of the hook 3 has an initial position corresponding to the position of the threading port 2-4 for the optical fiber 101 to enter the hook portion 3-2, and also has a hooking position in which the optical fiber 101 is hooked into and wound around the ring cavity 5 by being pressed by the box body 2 after the box body 2 and the base 1 rotate relative to each other. During the movement of the hook portion 3-2 to the hooking position, the elastic member is deformed by force, thereby facilitating the resetting of the hook 3.

[0037] Specifically in the present embodiment, the hook 3 is hinged on the base 1, specifically, it is hinged on the end surface of the base 1 facing the box body 2 (i.e., the top surface of the base 1), and the hook 3 is located at the edge of the base 1 and on the outside of the annular convex edge 1-4. The hook 3 includes a rod portion 3-1, one end of the rod portion 3-1 is provided with a hinge shaft, and the hook portion 3-2 is provided at the other end of the rod portion 3-1. A hinge groove 1-1 is provided on the end surface of the base 1, and the hinge shaft of the hook 3 is installed in the hinge groove 1-1. Specifically, a socket for inserting the hinge shaft is provided on the groove wall of the hinge groove 1-1. The axis of the hinge shaft is perpendicular to the central axis of the base 1. The above-mentioned elastic member is a torsion spring (not shown in the figure) installed on the hinge shaft. Under the action of the torsion spring, the hinge shaft is connected to the base 1. Figure 7 For example, the hook 3 has only the freedom to rotate counterclockwise and cannot rotate clockwise. It should be noted that the installation of the torsion spring and the effects that can be achieved are well known to those skilled in the art and will not be described in detail in the present invention.

[0038] like Figure 4 As shown, the box body 2 is provided with a swing cavity 2-7 which is connected with the ring cavity 5 and the threading port 2-4 for the hook portion 3-2 of the hook 3 to swing to the hooking position, so that the box body 2 presses the hook portion 3-2 and makes the hook 3 swing. Figure 6 As shown, the cavity wall of the swing cavity 2-7 used to press the hook portion 3-2 to swing to the hook-in position is an arc-shaped wall 2-7-1, which makes the movement of the hook 3 smoother and avoids jamming. At the same time, a transition cavity 2-6 is also provided between the swing cavity 2-7 and the threading port 2-4 for keeping the hook 3 stationary in the initial stage of relative rotation between the box body 2 and the base 1. When the hook portion 3-2 is in the initial position, it is arranged toward the transition cavity 2-6 and the swing cavity 2-7. In this way, when in use, the hook portion 3-2 can first be adjusted to the initial position corresponding to the position of the threading port 2-4 by rotating the box body 2. At this time, the state of the hook 3 is as follows: Figure 3 , Figure 4 as well as Fig. 9 As shown in (a) in the figure; then the electro-optic modulator 100 is placed in the placement slot 2-1, the power interface 103 of the electro-optic modulator 100 is inserted into the power interface exposure port 2-2, the signal interface 102 is inserted into the signal interface exposure port 2-3, the optical fiber 101 passes through the threading port 2-4, and the optical fiber 101 can be manually assisted to enter the hook portion 3-2 of the hook 3. At this time, the state of the electro-optic modulator 100 is as follows: Fig.10 As shown in (a) in .

[0039] Then rotate the box body 2 clockwise, or rotate the base 1 counterclockwise, and the hook 3 can bring the optical fiber 101 into the transition cavity 2-6. Since the torsion spring has a certain pre-pressure, the hook 3 does not rotate during this process, which ensures that the optical fiber 101 can be smoothly brought into the annular cavity 5 later. When the box body 2 and the base 1 rotate relative to each other to a certain extent, the hook portion 3-2 of the hook 3 contacts the arc wall 2-7-1, as shown in FIG. Fig. 9 As shown in (b); thereafter, the arcuate wall 2-7-1 begins to press the hook portion 3-2 and causes the hook 3 to swing downward. During this process, the torsion spring is deformed by force, and the optical fiber 101 is always hooked by the hook portion 3-2 and gradually pulled downward until the hook 3 is separated from the arcuate wall 2-7-1 and enters the annular cavity 5, as shown in FIG. Fig. 9 As shown in (c) and (d) in FIG. 1 , the hook portion 3-2 moves to the hooking position, and the optical fiber 101 is also brought into the ring cavity 5; as the base 1 and the box body 2 continue to rotate relative to each other, the hook 3 continues to move into the ring cavity 5, as shown in FIG. Fig. 9 As shown in (e) in FIG. 1 , the optical fiber 101 is gradually wound in the ring cavity 5, and the optical fiber extending outward is gradually reduced, as shown in FIG. Fig.10 The base 1 and the box body 2 continue to rotate relative to each other until the optical fiber 101 almost completely enters the ring cavity 5, as shown in (b) in FIG. Fig.10 As shown in (c), at this time, only one end of the optical fiber 101 is left outside, thereby realizing the storage of the extended optical fiber.

[0040] Since the annular cavity 5 is located below the power interface exposure opening 2-2 and the signal interface exposure opening 2-3, the stored optical fiber will not block the two interfaces of the electro-optical modulator 100, ensuring that the interfaces can be normally exposed for plugging with the detection device. Thus, the present invention sets a movable hook 3 so that the optical fiber 101 can be stored away from the two interfaces of the electro-optical modulator 100, thereby reducing the protruding length of the optical fiber and avoiding optical fiber breakage due to improper operation. At the same time, it can also avoid interference with other test equipment and test processes, ensuring the smooth progress of the test process.

[0041] Since the torsion spring is deformed by force during the swinging process of the hook 3, after the test is completed, the hook 3 will be reset when it moves to the position corresponding to the swing cavity 2-7 through the reverse relative rotation of the base 1 and the box body 2, which is convenient for the reuse of the material box. During the reverse relative rotation of the base 1 and the box body 2, the end of the optical fiber 101 can be pulled by hand to assist the optical fiber 101 to exit the ring cavity 5 until it can be taken out from the threading port 2-4.

[0042] like Figure 4 , Figure 5 and Figure 6 As shown, the transition cavity 2-6 and the swing cavity 2-7 are located on the side of the threading port 2-4 away from the signal interface exposed port 2-3 to avoid interference with the signal interface exposed port 2-3. Obviously, the transition cavity 2-6 penetrates the side wall of the threading port 2-4, and the bottom wall of the threading port 2-4 is also penetrated, so that the hook portion 3-2 of the hook 3 can extend into the threading port 2-4 and can move into the transition cavity 2-6. In addition, since the hook 3 and the threading port 2-4 have certain sizes, in order to facilitate the adjustment of the hook portion 3-2 to switch to the initial position, as shown in FIG. Figure 4 , Figure 5and Figure 6 As shown, an avoidance cavity 2-8 is provided on the side wall on the other side of the threading port 2-4, so that when the hook 3 moves to this position, part of the structure can enter the avoidance cavity 2-8, so that the hook part 3-2 can be exposed, and at the same time the hook 3 can also be blocked by the cavity wall of the avoidance cavity 2-8, so as to clearly know that the hook 3 has been adjusted into place.

[0043] In this embodiment, if Figure 3 and Figure 4 As shown, the base 1 and the box body 2 are connected by screws 4. Specifically, a through hole 2-10 ( Figure 5 and Figure 6 As shown, the through hole 2-10 is located on the bottom wall of the placement groove 2-1 and penetrates the bottom wall of the groove. A threaded hole connected with the screw 4 is provided at the center of the base 1. The tightening degree of the screw 4 satisfies that the base 1 and the box body 2 can rotate relative to each other. This structure is relatively simple and convenient for processing, manufacturing and assembly.

[0044] Furthermore, if Figure 7 As shown, a boss 1-2 is provided at the center of the base 1, and the threaded hole is provided on the boss 1-2. Figure 5 As shown, the above-mentioned through-hole 2-10 is a stepped hole, including a large-diameter hole for the head of the screw 4 to sink into and a small-diameter hole for the boss 1-2 to insert, so as to prevent the head of the screw 4 from protruding and affecting the installation of the optoelectronic device. There is a matching gap between the boss 1-2 and the small-diameter hole, which can realize the positioning between the base 1 and the box body 2, and the connection between the base 1 and the box body 2, and also facilitate the relative rotation between the two.

[0045] In addition, if Figure 7 As shown, an annular positioning protrusion 1-3 is arranged on the top surface of the base 1, and the positioning protrusion 1-3 is arranged around the center of the base 1, located on the outside of the protrusion 1-2, and located on the inside of the annular protrusion 1-4. Figure 6 As shown, an annular positioning groove 2-9 is provided on the bottom surface of the box body 2, and the positioning groove 2-9 is provided around the center of the box body 2 and is located outside the through hole 2-10. When the base 1 and the box body 2 are assembled, the positioning protrusion 1-3 is inserted into the positioning groove 2-9 with a matching gap therebetween, so that the positioning between the base 1 and the box body 2 can be achieved, and the relative rotation between the base 1 and the box body 2 is also facilitated.

[0046] In addition, the base 1 and the box body 2 can also be built with high-attenuation magnetic materials, so that the upper and lower surfaces of the material box can locate and attract each other when they contact other material boxes, thereby realizing the combination of multiple material boxes and completing batch testing.

[0047] In other embodiments of the optoelectronic device test kit: the optoelectronic device test kit can also be used for other types of electro-optic modulators, such as Figure 2 As shown in the electro-optic modulator 200, since there are optical fibers 101 on both sides of the electro-optic modulator 200, two threading ports need to be set on the box body of the material box, and of course two hooks need to be installed. The specific form is the same as the previous embodiment, but it should be noted that the hook parts of the two hooks are facing opposite directions. In addition, since the power interface and signal interface of the electro-optic modulator 200 are located on the two side walls, the setting position of the exposure port is different from that of the previous embodiment. It is only necessary to design the position of the exposure port according to the shape and size of the electro-optic modulator 200.

[0048] In other embodiments of the optoelectronic device test box: the optoelectronic device test box can also be used for other types of optoelectronic devices, such as photoelectric detectors with optical fibers. The shape and size of the groove on the box and the position of the exposure port are determined according to the specific structure of the photoelectric detector.

[0049] In other embodiments of the photoelectric device test material box: instead of setting a boss at the center of the base and setting a threaded hole on the boss, a threaded hole can be directly set on the base, thereby eliminating the boss. In this case, the screw completely passes through the box body and is connected with the threaded hole on the base.

[0050] In other embodiments of the optoelectronic device test box: without affecting the placement of the optoelectronic device and the storage of the optical fiber, the screw holes on the box body may not be countersunk holes, and the screw heads protrude from the bottom of the placement slot.

[0051] In other embodiments of the photoelectric device test material box: the screw through hole can also be set on the base, and the threaded hole is set on the box body in this case, so that the tightening degree of the screw can also meet the relative rotation between the base and the box body.

[0052] In other embodiments of the optoelectronic device test material box: the positioning protrusion can be arranged on the bottom surface of the box body, and the positioning groove is arranged on the top surface of the base.

[0053] In other embodiments of the optoelectronic device test material box: the positioning protrusion and positioning groove may not be set. In this case, the positioning between the base and the box body is achieved by sliding cooperation between the annular protrusion on the base and the circumferential inner groove wall of the annular groove on the box body. In this case, the positioning of the protrusion and the perforation may be provided at the same time, or of course, there may be no positioning.

[0054] In other embodiments of the photoelectric device test material box: the annular ridge may not be provided, and the positioning of the base and the box body is achieved by relying on the positioning protrusions and positioning grooves on the base and the box body. In this case, the positioning of the protrusions and the through holes may be provided at the same time, or of course, there may be no positioning.

[0055] In other embodiments of the optoelectronic device test box: only the positioning protrusions and positioning grooves, or only the annular protrusion and the circumferential inner groove wall of the annular groove, or only the bosses and the through holes can be used to achieve the positioning fit between the base and the box body; of course, in other embodiments, these positioning measures may not be provided, and screws can be used to achieve the positioning fit between the base and the box body.

[0056] In other embodiments of the optoelectronic device test box: the rotational cooperation between the base and the box body may not be achieved by screws, for example, by relying on the appropriate interference between the positioning protrusion and the positioning groove and / or the appropriate interference between the annular protrusion and the circumferential inner groove wall of the annular groove, to ensure that the base and the box body can both rotate relative to each other and remain in a certain position after rotation.

[0057] In other embodiments of the optoelectronic device test material box: the cavity wall of the swing cavity used to press the hook portion to swing to the hooking position can also be an inclined surface arranged obliquely.

[0058] In other embodiments of the photoelectric device test material box: a transition cavity may not be provided between the swing cavity and the threading port, and when the base and the box body rotate relatively, the hook directly enters the swing cavity.

[0059] In other embodiments of the optoelectronic device test cartridge: the rod portion of the hook may not be directly provided with a hinge shaft, but may be provided with a through hole for the hinge shaft to pass through, so as to additionally install the hinge shaft.

[0060] In other embodiments of the optoelectronic device test material box: the hook portion can also be arranged to face away from the swing cavity when it is in the initial position. At this time, when the hook portion swings, the hook portion swings downward, and the optical fiber will not fall off the hook portion.

[0061] In other embodiments of the optoelectronic device test box: the swinging direction of the hook can also be adjusted, from only being able to swing counterclockwise to only being able to swing clockwise. At this time, a swinging cavity needs to be provided on the side of the threading port close to the exposed port of the signal interface, and the size of the swinging cavity is required not to interfere with the exposed port of the signal interface. At this time, there are also two possible directions of the hook, which can be facing the swinging cavity or facing away from the swinging cavity, as long as the size of the hook satisfies the requirement that the optical fiber will not fall off the hook during the swinging process.

[0062] In other embodiments of the optoelectronic device test box: for optoelectronic devices whose interfaces and optical fibers are not on the same side, the position of the swing cavity relative to the threading port can be set more flexibly and freely, and can be located on any side of the threading port.

[0063] In other embodiments of the optoelectronic device test box: the installation method of the hook may not be hinged, but may be installed on the base in a vertically movable manner. In this case, the elastic member is a tension spring or a compression spring. When the base and the box body rotate relative to each other, the box body will press the hook. The top pressure wall of the box body may be set as an inclined surface, so that the box body can generate a downward component force on the hook, forcing the hook to move downward, so that the hook leaves the threading port and enters the annular cavity. In this process, the tension spring or compression spring is deformed by the force.

[0064] In other embodiments of the optoelectronic device testing material box: an annular groove may be provided on the top surface of the base, and the annular groove and the box body together form an annular cavity.

[0065] An embodiment of the optoelectronic device testing equipment in the present invention is as follows: the optoelectronic device testing equipment includes a detection device and an optoelectronic device testing material box. The specific structure of the optoelectronic device testing material box is the same as that of the optoelectronic device testing material box in any of the above embodiments, which will not be repeated here.
