[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0044] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0045] During the production process of optical modules, a power test process is usually required. In this process, the optical module needs to be operated into a test system and a test circuit is connected to the optical module. The conductive probes in the circuit socket of the existing test circuit are mostly exposed to the environment and are easily damaged by mechanical impact.

[0046] Analysis of the above reasons shows that the conductive probe is easily damaged by impact when exposed to the environment. It is possible to consider providing a protective component for it. When there is no need for conductive connection, the protective component can autonomously shield the conductive probe. When conductive connection is required, the protective component can autonomously move away to expose the conductive probe.

[0047] In view of this, the utility model proposes a circuit socket, a circuit quick-connect assembly and an optical module test system, aiming to solve the problem that the conductive probe of the circuit socket in the existing optical module test system is easily damaged by mechanical impact.

[0048] See also Figure 1 , Figures 4 to 6 In one embodiment of the utility model, the circuit socket 1 includes a power supply structure 13 and a protection structure 14. The power supply structure 13 is formed with a plurality of power supply parts 131. The power supply parts 131 are extended in a first direction to contact and conduct with a plurality of adapter parts 21 of the circuit plug 2; the protection structure 14 is movably arranged on the power supply structure 13 along the first direction, and a plurality of via holes 141 are formed on the protection structure 14. The plurality of via holes 141 and the plurality of power supply parts 131 are arranged in a counterposition. The protection structure 14 has a protection position and an exposure position within its activity range, and the protection structure 14 can be reset to the protection position autonomously; when the protection structure 14 is in the protection position, the plurality of power supply parts 131 are relatively retracted into the via holes 141; when the protection structure 14 is in the exposure position, the plurality of power supply parts 131 are relatively protruded from the via holes 141.

[0049] It should be noted that the circuit plug connector 2 mentioned in this embodiment is used as a set with the circuit plug socket 1, and an adapter portion 21 is arranged thereon, which is aligned with the multiple power supply portions 131 in the circuit plug socket 1. In the power test scenario of the optical module, the circuit plug socket 1 can be set on the operating platform of the optical module test system, and the circuit plug connector 2 can be set on the transfer cart. The circuit plug connector 2 can also be set on the operating platform of the optical module test system, and the circuit socket head can be set on the transfer cart, and the transfer cart is used to transport it to the test station of the operating platform to achieve basic conduction between the multiple power supply portions 131 on the circuit plug socket 1 and the multiple adapter portions 21 on the circuit plug connector 2. The use scenario of the circuit plug socket 1 is not limited to this, and can also be applied to any other scenario where power supply is required, and this embodiment does not limit it;

[0050] It should be noted that the protection structure 14 can move along the first direction, and it should also have a limiting resistance to movement in other directions, so that it can play a protective role on the multiple power supply parts 131. The protection structure 14 has various structural forms, and its specific form is related to the length of the power supply part 131. For example, when the length of the power supply part 131 is short, the thickness of the protection structure 14 should be set to be thinner, so that it can ensure that when it moves to the exposed position, the power supply part 131 can be protruded from its via 141. This embodiment does not limit its specific structure.

[0051] It should be noted that the specific structural form of the multiple power supply parts 131 can also be set in the form of probes or syringes, which is not limited in this embodiment.

[0052] According to the technical solution of the present utility model, the circuit socket 1 can be arranged on the working platform of the optical module testing system. When the transfer cart loaded with the optical module moves to the testing station of the working platform, it is squeezed by the circuit plug connector 2 on the transfer cart along the first direction, and the protection structure 14 of the circuit socket 1 can be squeezed to the exposed position, so that the multiple power supply parts 131 of the power supply structure 13 protrude from the through holes 141 of the protection structure 14, thereby contacting and conducting with the multiple adapter parts 21 of the circuit plug connector 2. After the optical module test is completed and the transfer cart leaves the testing station, due to the loss of the squeezing effect of the circuit plug connector 2, the protection structure 14 of the circuit socket 1 can be reset to the protection position autonomously, and the multiple power supply parts 131 are relatively retracted into the through holes 141 of the protection structure 14, thereby being timely shielded and protected by the protection structure 14, thereby preventing the multiple power supply parts 131 from being subjected to mechanical impact from the external environment.

[0053] See also Figure 4 and Figure 5 In one embodiment, a proximity switch 132 is further provided on the power supply structure 13, and the proximity switch 132 is used to trigger a proximity signal when contacting the circuit plug connector 2; and / or,

[0054] A guide and reset structure 133 is further provided between the power supply structure 13 and the protection structure 14 . A plurality of guide and reset structures 133 are provided and arranged along the circumference of the protection structure 14 .

[0055] It should be noted that the above two parallel technical features "a proximity switch 132 is also provided on the power supply structure 13, and the proximity switch 132 is used to trigger a proximity signal when contacting the circuit plug connector 2" and "a guide reset structure 133 is also provided between the power supply structure 13 and the protection structure 14, and a plurality of guide reset structures 133 are provided and arranged along the peripheral side of the protection structure 14" can be set selectively or simultaneously. Obviously, the effect of setting them simultaneously is better;

[0056] It should be noted that the functions of the guide reset structure 133 include providing a guiding function for the protective structure 14 along the second direction and providing a reset force for the protective structure 14 toward the protective position. The guide reset structure 133 has various forms, for example, it may include a reset spring and a guide assembly, the guide assembly includes a guide rod and a guide sleeve sleeved on the guide rod, one end of the guide rod is arranged on the power supply structure 13, the guide sleeve is arranged on the protective structure 14, and the reset spring is sleeved on the guide rod and is located between the power supply structure 13 and the guide sleeve. In this way, the guiding and resetting requirements of the guide reset structure 133 can be met. Of course, the guide reset structure 133 can also be other structural forms, which are not limited to this in this embodiment.

[0057] According to the above technical solution, the proximity switch 132 can be used to trigger a proximity signal when the circuit contact head is close to the power supply structure 13, which means that the power supply part 131 and the adapter part 21 are in contact with each other. When receiving the proximity signal, the power supply control device can control the power supply of the test circuit or control the relevant indicator light to light up; by arranging multiple guide and reset structures 133 on the surrounding side of the protective structure 14, it can provide guidance and reset effects for various positions of the protective structure 14, thereby ensuring the smooth movement of the protective structure 14 and its anti-impact ability.

[0058] In the power test process of the optical module, there is usually a position deviation when the optical module is moved to the test station of the test system by using a transfer cart. Therefore, it is usually connected to the power manually. However, the manual connection method has the problems of low efficiency and high labor cost. In view of this, please refer to Figures 1 to 3 and Figure 6 In one embodiment, the circuit socket 1 also includes a mounting structure 11, and a floating structure 12 is arranged on the mounting structure 11. The floating structure 12 can float in a floating plane toward the first direction to have an initial position and a floating position. The floating structure 12 can reset to the initial position autonomously. The floating structure 12 is formed with a positioning portion 121 extending toward the first direction, and the positioning portion 121 is used to position and plug with the mating portion 22 of the circuit plug 2; the power supply structure 13 is arranged on the floating structure 12.

[0059] It should be noted that the circuit plug connector 2 mentioned in the present embodiment is provided with a mating portion 22 aligned with the positioning portion 121 in the circuit socket 1 to realize the function of plug-in positioning; wherein, the floating plane is a virtual plane, which is used to limit the floating motion trajectory of the floating structure 12. For example, when the first direction is in the X direction, the floating plane belongs to the YZ plane, and the floating setting of the floating structure 12 in the floating plane can be understood as moving in any direction in the plane. The initial position belongs to the position where the floating structure 12 is automatically reset without being affected by any external force, and the floating position belongs to any position of the floating structure 12 in the floating plane except the initial position. Therefore, there are many floating positions. Through the positioning and guiding effect of the mating portion 22 and the positioning, the floating structure 12 can move to the floating position corresponding to the circuit plug connector 2.

[0060] According to the technical solution of the present utility model, the mounting structure 11 of the circuit connector 1 is arranged on the working platform of the optical module testing system. When the transfer cart loaded with the optical module moves to the testing station of the working platform, even if there is a certain position deviation, since the mating portion 22 of the circuit connector 2 on the transfer cart can pre-contact with the positioning portion 121 of the circuit connector 1 in the first direction, the floating structure 12 is driven to move to a floating position corresponding to the position of the circuit connector 2 through the positioning and guiding effect of the positioning portion 121 and the mating portion 22. Thereafter, the multiple power supply portions 131 on the power supply structure 13 are directly opposite to the multiple adapter portions 21 on the circuit connector 2 in the first direction. In the subsequent process of the power supply portions 131 and the adapter portions 21 moving toward each other, the power supply portions 131 can be directly contacted and connected with the adapter portions 21, which changes the current situation in which the power connection process of the optical module is completely completed manually in the existing optical module testing process, improves the power connection efficiency of the optical module, and reduces the cost of manpower.

[0061] There are many ways to realize the floating movement of the floating structure 12 in the floating plane. For example, by pulling the floating structure 12 along different radial directions in the floating plane on the circumferential side of the floating structure 12 through multiple tension springs, the floating structure 12 can be floated and reset. However, this type of structure is relatively complex, and the repetition accuracy of the initial position of the floating structure 12 is difficult to guarantee. In view of this, in one embodiment, the mounting structure 11 includes a transverse movable portion 1121 that moves along a second direction, and the transverse movable portion 1121 is provided with a longitudinal movable portion 1122 that can move along a third direction; the floating structure 12 is arranged on the longitudinal movable portion 1122; wherein the second direction and the third direction are two directions perpendicular to each other in the floating plane.

[0062] It should be noted that since the second direction and the third direction are two directions perpendicular to each other in the floating plane, and the transverse movable part 1121 and the longitudinal movable part 1122 can move relative to each other, according to the above technical solution, the floating structure 12 can be adjusted to any floating position in the floating plane under the coordinated action of the transverse movable part 1121 and the longitudinal movable part 1122. At the same time, the structural form of the mounting structure 11 is relatively simple, and the floating structure 12 can be reset to the initial position by controlling the resetting of the transverse movable part 1121 and the longitudinal movable part 1122, thereby ensuring the repeatability of the initial position and facilitating the accurate plugging of the circuit plug connector 2 and the circuit socket 1.

[0063] Specifically, see Figure 3 In one embodiment, the transverse movable portion 1121 has two transverse mounting side walls 1121a opposite to each other in the second direction, and the longitudinal movable portion 1122 is respectively mounted to the two transverse mounting side walls 1121a at both ends in the second direction; and / or

[0064] The mounting structure 11 has two longitudinal mounting side walls 112 a opposite to each other in the third direction, and the transverse movable portion 1121 is respectively mounted to the two longitudinal mounting side walls 112 a at two ends in the third direction.

[0065] It should be noted that the longitudinal movable portion 1122 is connected to the corresponding transverse mounting side wall 1121a by sliding along the third direction at the end in the second direction, and the transverse movable portion 1121 is connected to the corresponding longitudinal mounting side wall 112a by sliding along the second direction at the end in the third direction;

[0066] It should be noted that the above two parallel technical features "the transverse movable part 1121 has two transverse mounting side walls 1121a opposite to each other in the second direction, and the longitudinal movable part 1122 is respectively mounted to the two transverse mounting side walls 1121a at both ends of the second direction" and "the mounting structure 11 has two longitudinal mounting side walls 112a opposite to each other in the third direction, and the transverse movable part 1121 is respectively mounted to the two longitudinal mounting side walls 112a at both ends of the third direction" can be set selectively or simultaneously. Obviously, the effect of setting them simultaneously is better.

[0067] According to the above technical solution, by setting two transverse mounting side walls 1121a, it is possible to provide mounting bases for both ends of the longitudinal movable part 1122, so that the center of gravity of the longitudinal movable part 1122 is between the two transverse mounting side walls 1121a, which is beneficial to ensure the smoothness of the longitudinal movable part 1122 when it moves on the transverse movable part 1121. Similarly, by setting two longitudinal mounting side walls 112a, it is possible to provide mounting bases for both ends of the transverse movable part 1121, so that the center of gravity of the transverse movable part 1121 is between the two longitudinal mounting side walls 112a, which is beneficial to ensure the smoothness of the transverse movable part 1121 when it moves on the mounting structure 11.

[0068] Specifically, see Figure 3 In one embodiment, a first guide component 17 is provided between the end of the longitudinal movable portion 1122 in the second direction and the corresponding transverse mounting side wall 1121a to provide a guiding function along the third direction, and a second guide component 18 is provided between the end of the transverse movable portion 1121 in the third direction and the corresponding longitudinal mounting side wall 112a to provide a guiding function along the second direction.

[0069] Specifically, regarding the reset implementation form of the floating structure 12, in one embodiment, a first elastic member 1123 is arranged between the transverse movable part 1121 and the longitudinal movable part 1122; a second elastic member 1124 is arranged between the transverse movable part 1121 and the mounting structure 11; under the pushing action of the first elastic member 1123 and the second elastic member 1124, the floating structure 12 can autonomously reset to the initial position.

[0070] It should be noted that the first elastic member 1123 and the second elastic member 1124 may be in the form of elastic rubber or a spring, and this embodiment does not limit their specific structural forms.

[0071] According to the above technical solution, by setting the first elastic member 1123, a thrust can be provided for the resetting of the transverse movable part 1121, and by setting the second elastic member 1124, a thrust can be provided for the resetting of the longitudinal movable part 1122. With the cooperation of the first elastic member 1123 and the second elastic member 1124, it can be ensured that the floating structure 12 is accurately and quickly reset to the initial position.

[0072] The process of plugging the multiple power supply parts 131 of the circuit socket 1 and the multiple adapter parts 21 of the circuit plug connector 2 can be achieved by manually pushing the transfer cart, but the force of manual pushing is not easy to control, which may cause the multiple power supply parts 131 and the multiple adapter parts 21 to collide and be damaged. In view of this, please refer to Figure 1 and Figure 2In one embodiment, the mounting structure 11 includes a mounting seat 111 and a movable seat 112 . The movable seat 112 is movably disposed on the mounting seat 111 along a first direction. The transverse movable portion 1121 is disposed on the movable seat 112 .

[0073] It should be noted that the movement of the movable seat 112 relative to the mounting seat 111 can be completed by manpower or by other means. This embodiment only limits the movable seat 112 to be able to move along the first direction, and does not limit its movement form.

[0074] According to the above technical solution, through the movable adjustment of the movable seat 112, the multiple power supply parts 131 of the circuit socket 1 and the multiple adapter parts 21 of the circuit plug connector 2 can be easily connected to each other. Since the process is relatively controllable, it is not easy for the multiple power supply parts 131 to collide with the multiple adapter parts 21. Moreover, after the test is completed, the multiple power supply parts 131 can be driven to detach from the multiple adapter parts 21 through the movable seat 112, so that the transfer cart can be easily pulled away from the optical module testing system.

[0075] Further, in one embodiment, a driving device 15 is disposed on the mounting seat 111, and the driving device 15 has a driving part movable along the first direction, and the driving part is disposed on the movable seat 112; and / or,

[0076] A linear guide assembly 16 is disposed between the mounting seat 111 and the movable seat 112 , and the linear guide assembly 16 is used to provide guidance for the movable seat 112 in a first direction.

[0077] It should be noted that the specific structure of the driving device 15 can be a push rod motor or a driving cylinder, which is not limited in this embodiment. The specific structure of the linear guide assembly 16 can be a linear guide rail slider structure or a guide rod sleeve structure, which is also not limited in this embodiment.

[0078] It should be noted that the above two parallel technical features "a driving device 15 is arranged on the mounting seat 111, the driving device 15 has a driving part that moves along the first direction, and the driving part is arranged on the movable seat 112" and "a linear guide assembly 16 is arranged between the mounting seat 111 and the movable seat 112, and the linear guide assembly 16 is used to provide guidance for the movable seat 112 in the first direction" can be set one by one or at the same time. Obviously, the effect of setting them at the same time is better.

[0079] According to the above technical solution, a driving device 15 is provided to drive the movable seat 112 to move through the driving part, so as to automatically complete the mutual plugging of the power supply part 131 of the circuit socket 1 and the adapter part 21 of the circuit connector 2, thereby further reducing the labor intensity of manual labor and improving the plugging and unplugging efficiency of the power supply part 131 and the adapter part 21. The linear guide assembly 16 is provided to provide a connection basis for the movable seat 112 and the mounting seat 111, and also to provide guidance along the first direction, thereby ensuring the accurate plugging and connection between the adapter part 21 and the power supply part 131.

[0080] For details, please refer to Figure 3 In one embodiment, the movable seat 112 includes a first mounting frame, the horizontal movable portion 1121 includes a second mounting frame, the vertical movable portion 1122 includes a third mounting frame, the second mounting frame moves in a second direction within the first mounting frame, and the third mounting frame moves in a third direction within the second mounting frame. The first mounting frame includes two vertical mounting side walls 112a, the second frame includes two horizontal mounting side walls 1121a, and the floating structure 12 is arranged in the third frame.

[0081] Generally speaking, the test circuit needs to form a power supply loop, so at least two sets of circuit adapter components are required between the transfer cart and the optical module test system. The two sets of circuit adapter components can be set separately, but the separate setting will cause the power connection lines to occupy too much system space. In view of this, in one embodiment, the power supply structure 13 and the protection structure 14 are combined into a power supply protection group in a one-to-one correspondence. Two sets of power supply protection groups are set in the extension direction of the floating plane. The two sets of power supply protection groups are used to form a power supply loop with the two sets of adapter groups on the circuit plug 2. According to the above technical solution, a power supply loop can be formed by setting two power supply protection groups. At the same time, the two power supply protection groups are set on the same floating structure 12, which can ensure that the respective power connection lines extend in parallel, that is, the occupation of the system space by the power connection lines is reduced.

[0082] The position accuracy of the transfer cart usually has deviations. The floating structure 12 needs to be positioned to the corresponding floating position through the contact between the positioning part 121 and the matching part 22. Only then can the power supply part 131 and the adapter part 21 be contacted and connected. To ensure the order of positioning and connection, please refer to Figure 4 or Figure 5 In one embodiment, in the first direction, the end of the positioning portion 121 is disposed farther from the floating structure 12 than the power supply portion 131. Thus, the positioning portion 121 can contact the circuit plug 2 before the power supply portion 131, and the floating structure 12 can be positioned in advance.

[0083] It should be noted that the above two parallel technical solutions "the power supply structure 13 and the protection structure 14 are combined into a power supply protection group in a one-to-one correspondence, and two groups of power supply protection groups are arranged in the extension direction of the floating plane, and the two groups of power supply protection groups are used to form a power supply loop with the two groups of adapter groups on the circuit plug 2" and "in the first direction, the end of the positioning part 121 is arranged farther away from the floating structure 12 than the power supply part 131" can be set one by one or at the same time. Obviously, the effect of setting them at the same time is better.

[0084] See also Figure 1 The utility model also proposes a circuit quick-connect assembly 100, which includes a circuit plug connector 2 and any of the above-mentioned circuit sockets 1, wherein the circuit plug connector 2 has a plurality of adapter parts 21, and the circuit plug connector 2 can push the protective structure 14 of the circuit socket 1 to move to an exposed position, so that the plurality of adapter parts 21 can contact and conduct to a plurality of power supply parts 131. The specific structure of the circuit socket 1 refers to the above-mentioned embodiment. Since the circuit quick-connect assembly 100 adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be described one by one here. Among them, the application scenario of the circuit quick-connect assembly 100 is not limited to the optical module test system, but can also be any other scenario that requires power connection.

[0085] The utility model also proposes an optical module testing system, which includes an operating platform, a transfer cart and the above-mentioned circuit quick-connect assembly 100. The operating platform is formed with a test station; the transfer cart can be operated to the test station, and the transfer cart is used to transfer the optical module to be tested; the circuit socket 1 of the circuit quick-connect assembly 100 is set on the operating platform, and the circuit plug connector 2 of the circuit quick-connect assembly 100 is set on the transfer cart; when the transfer cart is operated to the test station, the multiple power connection parts of the circuit socket 1 can contact and conduct with the multiple adapter parts 21 of the circuit plug connector 2. The specific structure of the circuit quick-connect assembly 100 refers to the above-mentioned embodiment. Since the optical module testing system adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0086] According to the technical solution of the utility model, the circuit socket 1 is arranged on the working platform of the optical module testing system. When the transfer cart loaded with the optical module moves to the testing station of the working platform, the circuit socket 1 is squeezed along the first direction by the circuit plug connector 2 on the transfer cart, and the protection structure 14 of the circuit socket 1 can be squeezed to the exposed position, so that the multiple power supply parts 131 of the power supply structure 13 protrude from the through holes 141 of the protection structure 14, thereby contacting and conducting with the multiple adapter parts 21 of the circuit plug connector 2. After the optical module test is completed and the transfer cart leaves the testing station, the protection structure 14 of the circuit socket 1 can be reset to the protection position autonomously due to the loss of the squeezing effect of the circuit plug connector 2, and the multiple power supply parts 131 are relatively retracted into the through holes 141 of the protection structure 14, thereby being timely shielded and protected by the protection structure 14, thereby preventing the multiple power supply parts 131 from being subjected to mechanical impact from the external environment.
