TECHNICAL FIELD
[0001] The present application relates to the technical field of flexible circuit board production, in particular to a detection and identification device and system for a flexible circuit board connector. BACKGROUND
[0002] At present, new energy vehicles have higher requirements for power battery packs in terms of specific energy, volume density, lightweight, safety and the like. In order to meet the requirements, the power battery is usually composed of multiple battery modules under the premise of ensuring the safety of the power battery, and the battery module is composed of multiple single batteries. The power battery adopts a circuit board to sample the single batteries in the battery module to monitor the working condition of the single batteries in real time. The use of single battery sampling and other means improves the integration of the power battery pack, thereby improving the specific energy and volume density of the power battery pack. At the same time, due to the use of single battery sampling, the safety, lightweight and other performances of the power battery pack are improved, and the cost is reduced.
[0003] The existing single battery sampling is to design a connector at the end of an FPC (Flexible Printed Circuit, also known as flexible circuit board), and to convert the voltage, temperature and other information of the sampled single batteries to a sampling wire harness through the connector. The sampling wire harness cooperates with the connector on the battery management system control board to complete the transmission of information.
[0004] Most power battery packs are not one, and each set of battery pack needs to be welded with an FPC circuit board to detect signals. At the same time, the interface positions of each set of battery pack are not completely symmetrical, so different types of connectors are needed to distinguish them, that is, the connectors need to be distinguished according to the differences in their appearances.
[0005] However, the existing flexible circuit board connector still relies on manual visual inspection in the appearance distinguishing inspection process. This manual identification and inspection method is not only low in efficiency but also has a high error rate. SUMMARY
[0006] The present application aims to solve the problem of low efficiency and high error rate of manual identification and inspection of the existing flexible circuit board connector. The present application provides a detection and identification device and system for a flexible circuit board connector, which can quickly and accurately identify different types of connectors without affecting the function test of the circuit.
[0007] To solve the above technical problems, the embodiments of the present application provide a detection and identification device for a flexible circuit board connector, comprising:
[0008] foolproof probe and identification probe;
[0009] The first fixed module is internally provided with a first fixed hole for inserting the fool-proof probe;
[0010] The second fixed module is internally provided with a second fixed hole for inserting the identification probe. When the first fixed module is connected with the second fixed module, the first fixed hole and the second fixed hole are in communication.
[0011] The limiting unit is arranged between the first fixed hole and the second fixed hole to limit the fool-proof probe from entering the second fixed hole or limit the identification probe from entering the first fixed hole.
[0012] The limiting hole of the limiting unit is arranged in the first fixed module and axially communicated with the first fixed hole.
[0013] The limiting hole is a planar hole.
[0014] The inner diameter of the limiting hole is greater than the diameter of the end of the fool-proof probe opposite to the identification probe and less than the diameter of the end of the identification probe opposite to the fool-proof probe.
[0015] The first fixed module is detachably connected with the second fixed module through the fastener.
[0016] The two fool-proof probes and the two identification probes are respectively inserted into the two first fixed holes and the two second fixed holes.
[0017] The first fixed hole is provided with a first observation part, and / or the second fixed hole is provided with a second observation part.
[0018] The fool-proof probe is threadedly connected with the first fixed hole.
[0019] The embodiments of the present application also provide a detection and identification system of a flexible circuit board connector, which comprises:
[0020] The detection and identification device of the flexible circuit board connector as described above;
[0021] The fool-proof probe pushing device is in contact with the fool-proof probe of the detection and identification device and pushes the fool-proof probe along the first fixed hole of the detection and identification device towards the second fixed hole.
[0022] The probe identification module is electrically connected with the identification probe of the detection and identification device.
[0023] Compared with the prior art, the detection and identification device and the detection and identification system of the flexible circuit board connector have the following advantages:
[0024] By arranging the first fixing module and the second fixing module, the first fixing hole and the second fixing hole are arranged in the first fixing module and the second fixing module respectively, the foolproof probe and the identification probe are inserted into the first fixing hole and the second fixing hole respectively, the first fixing hole and the second fixing hole are communicated when the first fixing module and the second fixing module are connected. And by arranging the limiting unit between the first fixing hole and the second fixing hole, the first fixing hole and the second fixing hole are separated, so that the foolproof probe and the identification probe can be separated, and the foolproof probe is limited to enter the second fixing hole or the identification probe is limited to enter the first fixing hole, so that the foolproof probe and the identification probe are in a non-contact state before detection, and the foolproof probe and the identification probe are in a contact state when detection is performed. One end of the foolproof probe is used to contact the identification probe, and the other end of the foolproof probe contacts the corresponding position of the connector. If the connector is correctly mounted, the foolproof probe and the identification probe are in a conduction state when the detection and identification of the connector are performed, and then whether the probes are in a conduction state is used to quickly and accurately judge different models of the connector.

[0031] The present application is explained by specific embodiments, and other advantages and effects of the present application can be easily understood by those skilled in the art from the contents disclosed in the specification.
[0032] Reference will now be made to the drawings to describe the exemplary embodiments of the present application in detail.

[0034] It is also to be noted that the relational terms herein such as first and second and the like are used solely to distinguish one entity or action from another, without necessarily requiring or implying any actual such relationship or order between or among the entities or actions. Also, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.
[0035] The inventor found that in the prior art, the connector of the flexible circuit board is provided with a protrusion as a fool-proof structure in appearance, but the fool-proof protrusions provided between different types of connectors are small in difference, and the mark part is not obvious, so that when relying on manual visual inspection, it is easy to make mistakes, and such manual identification method is inefficient.
[0036] As Figs. 1-3 shown, Figs. 1-3 A structure diagram of a detection and identification device of a flexible circuit board connector according to an embodiment of the present application is shown. In the present embodiment, the detection and identification device of the flexible circuit board connector comprises:
[0037] The foolproof probe 1 and the identification probe 2;
[0038] The first fixed module 3 is internally provided with a first fixed hole 311 for inserting the foolproof probe 1.
[0039] The second fixed module 4 is internally provided with a second fixed hole 411 for inserting the identification probe 2, and when the first fixed module 3 is connected with the second fixed module 4, the first fixed hole 311 and the second fixed hole 411 are in communication.
[0040] The limiting unit is arranged between the first fixed hole 311 and the second fixed hole 411 to limit the foolproof probe 1 from entering the second fixed hole 411 or limit the identification probe 2 from entering the first fixed hole 311.
[0041] The first fixed module 3 and the second fixed module 4 are arranged, the first fixed hole 311 and the second fixed hole 411 are arranged in the first fixed module 3 and the second fixed module 4 respectively, the foolproof probe 1 and the identification probe 2 are inserted into the first fixed hole 311 and the second fixed hole 411 respectively, the first fixed hole 311 and the second fixed hole 411 are in communication when the first fixed module 3 is connected with the second fixed module 4, and the limiting unit is arranged between the first fixed hole 311 and the second fixed hole 411 to separate the first fixed hole 311 and the second fixed hole 411, so that the foolproof probe 1 and the identification probe 2 can be separated, and the foolproof probe 1 is limited from entering the second fixed hole 411 or the identification probe 2 is limited from entering the first fixed hole 311, so that the foolproof probe 1 and the identification probe 2 are in a non-contact state before detection, and the foolproof probe 1 and the identification probe 2 are in a contact state when detection is performed. One end of the foolproof probe 1 is used to contact the identification probe 2, and the other end of the foolproof probe 1 contacts a corresponding position of the connector, if the connector is correctly mounted, the foolproof probe 1 and the identification probe 2 are in a conduction state when the connector is detected and identified, and then whether the probes are in a conduction state is used to quickly and accurately judge different models of the connector.
[0042] Specifically, the front end of the foolproof probe 1 contacts the end face of the connector, and the tail end is inserted into the first fixed hole 311; the front end of the identification probe 2 is connected with the PCB circuit board through a wire, and the tail end is inserted into the second fixed hole 411.
[0043] More specifically, the end face of the first fixing module 3 connected to the second fixing module 4 is flat, and the end face of the second fixing module 4 connected to the first fixing module 3 is also flat. The first fixing module 3 includes a first probe mounting portion 31 and a first connecting portion 32. Optionally, the first connecting portion 32 is plate-shaped, and the first connecting portion 32 is integrally formed with the first probe mounting portion 31. The first probe mounting portion 31 is along a first direction (e.g., ...). Fig. 1 The first connecting portion 32 extends along a second direction perpendicular to the first direction (as shown in the x-direction), and extends along a second direction perpendicular to the first direction (as shown in the x-direction). Fig. 1 (As shown in the y-direction). The first probe mounting portion 31 has a first fixing hole 311, which extends along the first direction and is used to insert the foolproof probe 1. The second fixing module 4 includes a second probe mounting portion 41 and a second connecting portion 42. Optionally, the second connecting portion 42 is plate-shaped and integrally formed with the second probe mounting portion 41. The second probe mounting portion 41 extends along the first direction, and the second connecting portion 42 extends along a second direction perpendicular to the first direction. The second probe mounting portion 41 has a second fixing hole 411, which extends along the first direction and is used to insert the identification probe 2.
[0044] Furthermore, the first fixing module 3 is detachably connected to the second fixing module 4 via fasteners. Specifically, in one embodiment of this invention, the first connecting portion 32 is provided with a first threaded hole 321, and the second connecting portion 42 is provided with a second threaded hole 421. When the first fixing module 3 and the second fixing module 4 are connected, the first fixing module 3 and the second fixing module 4 are fixedly connected together by inserting fasteners, such as screws, into the first threaded hole 321 and the second threaded hole 421. This facilitates disassembly, thereby making it easier to maintain or replace the probe. It is worth noting that the connection method of the first fixing module 3 and the second fixing module 4 is not limited to this; for example, a plug-in or snap-fit connection method can also be used.
[0045] It is worth noting that in this invention, the limiting unit can be a limiting hole 5, which is a cylindrical hole that axially communicates with the first fixing hole 311 and is located inside the first fixing module 3. Of course, the limiting unit can also be other structures that limit and separate the foolproof probe 1 and the identification probe 2. The specific configuration can be made according to actual needs.
[0046] Optionally, in one specific embodiment of the present invention, in order to simplify the structure and facilitate assembly and processing, the limiting hole 5 is a planar hole. In the present invention, in the initial state, the anti-foolproof probe 1 and the identification probe 2 can be separated by the limiting hole 5, and the two are in a non-contact state; in the working state, the anti-foolproof probe 1 passes through the limiting hole 5 to contact the identification probe 2.
[0047] Further, in the embodiment, the inner diameter of the limiting hole 5 is greater than the diameter of the end of the fool-proof probe 1 opposite to the identification probe 2, and is less than the diameter of the end of the identification probe 2 opposite to the fool-proof probe 1.
[0048] Specifically, the fool-proof probe 1 is inserted into the first fixed hole 311, wherein the front end of the fool-proof probe 1 is exposed outside and is responsible for contacting the connector, and the tail end of the fool-proof probe 1 is inserted into the first fixed hole 311 and can reach the position near the end face of the limiting hole 5. The identification probe 2 is inserted into the second fixed hole 411, wherein the front end of the identification probe 2 is inserted into the second fixed hole 411 and does not exceed the end face of the second fixed module 4, and the tail end of the identification probe 2 is connected to the PCB circuit board through a wire.
[0049] Since the inner diameter of the limiting hole 5 is less than the diameter of the tail end of the fool-proof probe 1 and is greater than the diameter of the front end of the identification probe 2, the tail end of the fool-proof probe 1 can pass through the limiting hole 4 to contact the front end of the identification probe 2, and the identification probe 2 is prevented from being outside the limiting hole 5. Therefore, the identification probe 2 is fixed in the second fixed hole 411, and in the working state, the fool-proof probe 1 can contact the identification probe 2, and in the initial state or non-working state, the fool-proof probe 1 does not contact the identification probe 2.
[0050] Optionally, the diameter of the middle section of the identification probe 2 is greater than the diameter of the front end, so as to limit the identification probe 2 from being withdrawn backward.
[0051] Further, the fool-proof probe 1 and the identification probe 2 each include two, the first fixed hole 311 and the second fixed hole 411 each include two, and the two fool-proof probes 1 are respectively inserted into the two first fixed holes 311, and the two identification probes 2 are respectively inserted into the two second fixed holes 411.
[0052] Specifically, the number of probes can be set according to the difference of the connector. Optionally, the number of probes is set to be even. In the embodiment, two fool-proof probes 1 and two identification probes 2 are provided, wherein one fool-proof probe 1 and one identification probe 2 form a group, and the other fool-proof probe 1 and the other identification probe 2 form another group. The front ends of the fool-proof probes 1 in the two groups contact the connector, wherein the fool-proof probe 1 in one group is inserted into the groove of the connector and is not compressed, and the fool-proof probe 1 in the other group contacts the surface of the connector and is compressed. Therefore, by compressing one fool-proof probe 1, the other fool-proof probe 1 is not compressed, the difference of the connector can be identified, and the model of the connector can be identified.
[0053] Further, the fool-proof probe 1 is threadedly connected to the first fixed hole 311.
[0054] Optionally, in this embodiment, the foolproof probe 1 includes a housing and a spring and probe body disposed within the housing. The first fixing hole 311 is configured with an internal thread, and the foolproof probe 1 is fixed within the first fixing hole 311 by being threadedly connected to it. Since the foolproof probe 1 is provided with a spring, when the foolproof probe 1 contacts the surface of the connector, the probe body is pushed in the direction of the identification probe, thereby contacting the identification probe 2. After the detection is completed, when the pushing of the probe body stops, the spring force allows the probe body to return to its initial state.
[0055] Furthermore, the first fixing hole 311 is provided with a first observation part 312, and / or the second fixing hole 411 is provided with a second observation part 412.
[0056] Specifically, such as Figs. 1-3 As shown, a portion of the first probe mounting portion 31 is hollowed out in the first fixing hole 311 within the first probe mounting portion 31 to expose the foolproof probe 1, facilitating observation of the insertion status of the foolproof probe 1. Optionally, the first observation portion 312 may be located in the middle portion of the first probe mounting portion 31. Furthermore, a portion of the second probe mounting portion 41 is hollowed out in the second fixing hole 411 within the second probe mounting portion 41 to expose the identification probe 2, facilitating observation of the insertion status of the identification probe 2. Optionally, the second observation portion 412 may be located at the right end of the second probe mounting portion 41.
[0057] According to the detection and identification device for flexible circuit board connectors provided by the present invention, a foolproof probe 1 and an identification probe 2 are respectively inserted into the first fixing hole 311 of the first fixing module 3 and the second fixing hole 411 of the second fixing module 4, and the outer shell of the foolproof probe 1 is fixed in the hole by threaded connection with the first fixing hole 311. The tail end of the foolproof probe 1 extends into the vicinity of the limiting hole 5, and the tail end face of the identification probe 2 is flush with the side of the second fixing module 4 opposite to the first fixing module 3. The first fixing module 3 and the second fixing module 4 are fixedly connected by fasteners, so that the first fixing hole 311, the limiting hole 5, and the second fixing hole 411 are axially connected. The front end of the identification probe 2 is connected to the PCB circuit board through a wire. The front end of the foolproof probe 1 is connected to the connector, one of the foolproof probes 1 contacts the end face of the connector and is compressed, so that the probe body of the foolproof probe 1 contacts the tail end of the identification probe 2. The other foolproof probe 1 is inserted into the groove of the connector and is not compressed. When in operation, if the circuit between the foolproof probe 1 and the identification probe 2 is connected, the connector is correctly mounted; if not connected, the connector is incorrectly mounted. Therefore, the flexible circuit board connector detection and identification device provided by this invention can quickly and accurately identify different types of connectors.
[0058] The embodiment of the present application further provides a detection and identification system of a flexible circuit board connector, comprising:
[0059] The detection and identification device of the flexible circuit board connector as described above;
[0060] The connector is in contact with the fool-proof probe 1 of the detection and identification device;
[0061] The probe identification module is electrically connected with the identification probe 2 of the detection and identification device, and is used for identifying whether the fool-proof probe 1 and the identification probe 2 are conductive.
[0062] Specifically, upper and lower limits (0.01Ω, 10Ω) are set at the resistance value when the fool-proof probe 1 and the identification probe 2 are conductive, and whether the flexible circuit board connector to be detected belongs to a correct qualified product is judged based on the upper and lower limits. When the connector is correctly mounted, the probe gap is in contact, the circuit is in a conductive state, the measured resistance value is in the interval, and the identification detection is determined as PASS. When the connector is incorrectly mounted, the probe gap is not in contact, the circuit is in an open state, the measured resistance value is 99999 infinity, and the identification detection is determined as NG.
[0063] The above embodiment only exemplarily illustrates the principle and effect of the present application, and is not used for limiting the present application. Any person skilled in the art can modify or change the above embodiment without departing from the spirit and scope of the present application. Therefore, all equivalent modifications or changes completed by those skilled in the art without departing from the spirit and technical thought disclosed by the present application should be covered by the claims of the present application.
