Description

Technical Field

[0001] This invention relates to a detection device and a probe module used in the detection device, and more specifically, to a detection device and probe module for battery detection. Background Technology

[0002] Qualified batteries need to undergo charge-discharge testing to ensure that the manufactured batteries meet safety specifications. The probe module of the testing device provides electrical connections to the battery under test for the testing procedure to be performed.

[0003] Each probe has one end for connecting to its corresponding cable, and the other end for the electrical connection to the battery under test. These cables are housed within the testing device and connected one by one to their respective probes. However, when consumable probes need to be replaced, the large number of cables significantly increases the difficulty of the replacement process. For example, with numerous probes in the testing device, if the corresponding cables are not individually tested during rewiring after replacing with new probes, connection errors can easily occur. However, the procedure of testing each cable individually is quite time-consuming and therefore difficult to perform. Summary of the Invention

[0004] One of the objectives of this invention is to reduce the difficulty of replacing the probe module in the detection device.

[0005] The second objective of this invention is to ensure the reliability of the probe module.

[0006] To achieve the above and other objectives, this invention proposes a probe module for providing electrical connection paths between the first and second electrode regions of a battery testing holder and the battery under test. The module includes: a base, a first polarity plate, a second polarity plate, a first upper connection group, a second upper connection group, at least one first lower connector, and at least one second lower connector. Both the first and second polarity plates are supported on the upper surface of the base, with the second polarity plate spaced apart from the first polarity plate. The first upper connection group provides the electrical connection path between the battery testing holder and the first polarity plate. The second upper connection group provides the electrical connection path between the battery testing holder and the second polarity plate. The first lower connector penetrates the base and is coupled to the first polarity plate. The first lower connector protrudes downward from the lower surface of the base and is retractable to movably provide the electrical connection path between the battery under test and the first polarity plate. The second lower connector passes through the base and is coupled to the second polarity plate. The second lower connector protrudes downward from the lower surface of the base and is retractable to provide an electrical connection path between the battery under test and the second polarity plate.

The contact section abuts against a first electrode area, wherein one end of each first pin opposite to the contact section is coupled to the first extension piece. The first fixing unit penetrates the first extension piece and fixes one end of the first extension piece to the front surface of the first floating connection seat. One end of each first elastic support is disposed in the base body through the first polar plate, and the other end is disposed in the first floating connection seat. Each first elastic support provides a restoring force to the first floating connection seat when subjected to downward external force, so as to increase the stable connection between the contact section of the first pin and the first electrode area.

[0011] According to one embodiment of the present invention, the second upper connection assembly includes: a second floating connection seat, a second extension plate, a plurality of second pins, at least one second fixing unit, and two second elastic supports. The second floating connection seat has supporting portions extending from both sides. The second extension plate extends from the upper surface of the second polar plate, extends towards the first polar plate through a first bend, extends below the second floating connection seat, and extends to the front surface of the second floating connection seat through the second bend. The second pins are disposed on the second floating connection seat and have a contact section exposed on the top surface of the second floating connection seat. The contact section abuts against the second electrode area, wherein one end of each second pin opposite to the contact section is coupled to the second extension plate. The second fixing unit penetrates the second extension plate and fixes one end of the second extension plate to the front surface of the second floating connection seat. One end of each second elastic support penetrates the second polar plate and is disposed on the seat body, and the other end is disposed on the second floating connection seat. Each second elastic support provides a restoring force to the second floating connection seat when subjected to downward external force, thereby increasing the stable connection between the contact section of the second pin and the first electrode area.

[0012] According to one embodiment of the present invention, a battery testing fixture includes a first insert piece serving as a first electrode region. A first upper connection group includes: a first connector, at least one first fixing unit, a first clamping piece, and a plurality of first pins. The first connector is disposed on the upper surface of a first polarity plate. The first clamping piece is disposed on the front side of the first connector via the first fixing unit, and a first slot for insertion of the first insert piece is formed between the first clamping piece and the first connector. Each first pin is disposed on the first connector and has a contact section protruding from the front side of the first connector. The contact section of each first pin is used to abut against the first insert piece inserted into the first slot, wherein one end of each first pin opposite to the contact section is coupled to the first polarity plate.

[0013] According to one embodiment of the present invention, a battery testing bracket is provided with a second insert piece serving as a second electrode region. The second upper connection group includes: a second connector, at least one second fixing unit, a second clamping piece, and a plurality of second pins. The second connector is disposed on the upper surface of the second polarity plate. The second clamping piece is disposed on the front side of the second connector via the second fixing unit, and a second slot for the second insert piece to be inserted is formed by a gap between the second clamping piece and the second connector. The second pins are disposed on the second connector and have a contact section protruding from the front side of the second connector. The contact section of each second pin is used to abut against the second insert piece inserted into the second slot, wherein one end of each second pin opposite to the contact section is coupled to the second polarity plate.

[0014] According to one embodiment of the present invention, the second polar plate has two circumferential portions extending toward both sides of the seat body on the upper surface of the seat body, and the two circumferential portions surround the first polar plate.

[0015] According to one embodiment of the present invention, there is a plurality of second lower connectors, including two second lower connectors that are respectively connected to the ends of the two circumferential portions and at least one second lower connector that is connected to the middle portion of the second polar plate, wherein the first lower connector is connected to a position of the first polar plate near a front end of the second polar plate.

[0016] According to one embodiment of the present invention, a first upper connection group is disposed on a first polar plate and is used to couple a first electrode region after the base is fixed to the battery testing frame, and a second upper connection group is disposed on a second polar plate and is used to couple a second electrode region after the base is fixed to the battery testing frame.

[0017] According to one embodiment of the present invention, the first lower connector and the second lower connector may also be spring probes.

[0018] To achieve the above and other objectives, the present invention further provides a testing device comprising: a battery testing frame and a plurality of the aforementioned probe modules. The battery testing frame includes a plurality of electrode portions of the battery to be tested, coupled one-to-one via cables, each electrode portion having a first electrode region and a second electrode region. The probe modules are fixed to the battery testing frame to provide an electrical connection path between the battery testing frame and the battery under test.

[0019] In this way, the probe module serves as the electrical connection interface between the battery testing rack and the battery under test, and all cables only need to be fixed to the battery testing rack. When the probe module needs to be replaced, there is no need to deal with the cables already fixed to the battery testing rack; the probe module can be easily replaced.

[0020] Furthermore, in the probe module, since each polarity has a dedicated coupling element corresponding to the battery test holder and the battery under test (for example, for one polarity, the first upper connection group corresponds to the first electrode area of ​​the battery test holder, and the first lower connection member corresponds to the battery under test), when the test procedure is performed, only the first and second lower connections are frequently pressed against and compressed (coupled to the battery under test) or disengaged and reset (removed from the battery under test). This ensures that the first and second electrode areas of the battery test holder are not affected, and the electrical contacts are not prone to degradation and damage due to frequent re-pressing, thus ensuring the reliability of the probe module.

Detailed Implementation

[0022] To fully understand the purpose, features, and effects of the present invention, the present invention will now be described in detail with reference to the following specific embodiments and accompanying drawings:

[0023] In this application, the terms "a" or "an" are used to describe units, components, structures, devices, modules, systems, parts, or regions, etc. This is used merely for ease of explanation and to provide a general meaning for the scope of the invention. Therefore, unless it is obvious otherwise, this description should be understood to include one or at least one, and the singular also includes the plural.

[0024] In this application, the terms "comprising," "including," "having," or any other similar terms described mean not only limited to the elements listed in this application, but may include other elements not expressly listed but which are generally inherent in the unit, component, structure, device, module, system, part, or region.

[0025] In this application, the terms "first" or "second" and similar ordinal numbers are used to distinguish or refer to elements, structures, parts or regions that are related to the same or similar entities, and do not necessarily imply a spatial order of such elements, structures, parts or regions. It should be understood that, in certain situations or configurations, ordinal numbers may be used interchangeably without affecting the implementation of the invention.

[0026] In this application, the term "coupled" may refer to two or more elements or devices making direct physical contact with each other, or making indirect physical contact with each other, or two or more elements or devices operating or acting with each other, or direct or indirect electrical (electrical or electrical signal) connection.

[0027] Please refer to the following at the same time Figure 1 and Figure 2 , Figure 1 This is a schematic diagram illustrating the electrical connection between a detection device and a battery under test according to an embodiment of the present invention. Figure 2 This is a perspective view of a detection device according to an embodiment of the present invention.

[0028] The testing device includes a battery testing rack 100 and multiple probe modules 300. For ease of explanation, Figure 2 This example only shows one battery testing rack 100 and one probe module 300. Figure 2 For example, a pair of electrode areas (110, 120) on the battery testing rack 100 can correspond to a set of cables (not shown, for example, one cable for each electrode area). One end of the cable is electrically connected to the corresponding electrode area (110 or 120), and the other end of the cable is extended to a cable connection area 130 located at one end of the battery testing rack 100. Each pair of electrode areas (110, 120) corresponds to a probe module 300. Figure 2 This refers to one of the probe modules, 300, as an example. Figure 2 In this example, the cables extending from each pair of electrode areas (110, 120) are gathered at one end of the elongated battery testing rack 100 and then connected to a power supply source at that end, for example, to an external power supply device. However, this is not a limitation; other configurations of the cable connection area 130, such as its location on the side of the battery testing rack 100, are also applicable.

[0029] Each probe module 300 serves as an electrical connection path between the battery testing rack 100 and a battery under test 200. The battery under test 200 has a first polarity electrode 210 and a second polarity electrode 220 for outputting electrical energy (discharging) or drawing electrical energy (charging). Through the probe module 300, the first polarity electrode 210 of the battery under test 200 can be coupled to the first electrode region 110 of the battery testing rack 100, and the second polarity electrode 220 of the battery under test 200 can be coupled to the second electrode region 120 of the battery testing rack 100.

[0030] like Figure 1 As shown, the probe module 300 includes: a base 303, a first polarity plate 301, a second polarity plate 302, a first upper connecting group 310, a second upper connecting group 320, a first lower connector 319, and a second lower connector 329. The first polarity plate 301 and the second polarity plate 302 are spaced apart from each other, and both the first polarity plate 301 and the second polarity plate 302 are supported on the upper surface of the base 303. The first polarity plate 301 and the second polarity plate 302 each occupy different areas on the upper surface of the base 303.

[0031] The first upper connection group 310 provides an electrical connection path between the battery detection holder 100 and the first polarity plate 301; on the other hand, the second upper connection group 320 provides an electrical connection path between the battery detection holder 100 and the second polarity plate 302.

[0032] A first lower connector 319 extends through the base 303 to couple to the first polarity plate 301. Furthermore, the first lower connector 319 is configured to protrude downwards from the lower surface of the base 303 and employs a retractable component, for example, but not limited to, a pogo pin, for abutment against the first polarity electrode 210 of the battery under test 200. The first lower connector 319 thereby movably provides an electrical connection path between the first polarity electrode 210 of the battery under test 200 and the first polarity plate 301.

[0033] Similarly, the second lower connector 329 may be configured to penetrate the base 303 and couple to the second polarity plate 302. The second lower connector 329 protrudes downward from the lower surface of the base 303 and may employ a retractable component, for example, but not limited to, a spring probe, for abutment against the second polarity electrode 220 of the battery under test 200 below. The second lower connector 329 thereby movably provides an electrical connection path between the second polarity electrode 220 of the battery under test 200 and the second polarity plate 302.

[0034] The number of first lower connectors 319 and second lower connectors 329 can be configured depending on the required current. When the current is larger, a larger number of first lower connectors 319 and second lower connectors 329 can be configured. These first lower connectors 319 are used to couple between the first polarity plate 301 and the first polarity electrode 210. Similarly, these second lower connectors 329 are used to couple between the second polarity plate 302 and the second polarity electrode 220.

[0035] The probe module 300 serves as the electrical connection interface between the battery testing rack 100 and the battery under test 200. The probe module 300 is detachably mounted on the battery testing rack 100. Each cable on the battery testing rack 100 is fixed and coupled to its corresponding probe module 300 via the corresponding first electrode area 110 and second electrode area 120. Therefore, the probe module 300 can be easily replaced for maintenance without affecting the cables mounted on the battery testing rack 100. These cables, unless damaged, can be securely attached to the battery testing rack 100 and remain independent of the probe module 300.

[0036] In terms of electrical connection, when the probe module 300 is placed on the battery testing rack 100 (e.g., via the locking hole 304 and the corresponding locking element), the first upper connection group 310 and the second upper connection group 320 of the probe module 300 can be coupled to the corresponding first electrode area 110 and second electrode area 120. By moving the battery testing rack 100 and / or the battery under test 200, the battery under test 200 abuts against the corresponding first lower connection member 319 and second lower connection member 329 of the probe module 300, allowing the testing procedure to proceed.

[0037] Generally, when one end of a single connector is pressed against, because it is the same component, it easily causes the other end to exert additional pressure on its electrical connection point, which can easily lead to poor contact over time. In contrast, in this embodiment, since the upper connecting group (310, 320) and the lower connecting members (319, 329) are separate, individually coupled polarized plates (301, 302), the pressure generated when the lower connecting members (319, 329) are coupled will not affect the upper connecting group (310, 320). Therefore, the stability of the electrical connection of the upper connecting group (310, 320) of the normally coupled battery testing bracket 100 can be ensured.

[0038] Next, please refer to the following: Figure 3 and Figure 4 , Figure 3 This is a three-dimensional schematic diagram of the probe module according to the first embodiment of the present invention. Figure 4 This is a partial cross-sectional schematic diagram of the probe module according to the first embodiment of the present invention.

[0039] In the first embodiment, the first upper connecting group 310 includes a first connecting seat 311 and a first upper connecting member 312; on the other hand, the second upper connecting group 320 includes a second connecting seat 321 and a second upper connecting member 322. Figure 4 As shown, the first connector 311 is disposed on the upper surface of the first polarity plate 301. For example, but not limited to this, the first connector 311 can be fixed to the base 303 by a fastener passing through the first polarity plate 301, so that the first connector 311 can be maintained on the first polarity plate 301. In addition, a first upper connector 312 is disposed on the first connector 311, and the upper end of the first upper connector 312 is used to abut against the first electrode area 110 of the battery detection holder 100 (which can be used simultaneously). Figure 2 The lower end of the first upper connector 312 is used to couple to the first polar plate 301.

[0040] In the first embodiment, the configuration of the second connecting seat 321 and the second upper connecting member 322 is similar to the configuration of the first connecting seat 311 and the first upper connecting member 312, so the second upper connecting group 320 will not be described in detail here.

[0041] In addition, such as Figure 3 and Figure 4 As shown, the position where the first lower connector 319 is coupled to the first polar plate 301 is different from the position where the first upper connector 312 is coupled to the first polar plate 301. When the first lower connector 319 is abutted, it will not affect the first upper connector 312. Similarly, the position where the second lower connector 329 is coupled to the second polar plate 302 is different from the position where the second upper connector 322 is coupled to the second polar plate 302. When the second lower connector 329 is abutted, it will not affect the second upper connector 322. Furthermore, the first upper connector 312 and the second upper connector 322 can be made of retractable components, for example, but not limited to, such as a spring probe. And, as... Figure 3 and Figure 4 As shown, the first connecting seat 311 and the second connecting seat 321 may be provided with protruding limiting portions on both sides of the top surface, which can limit the shortest distance between the battery detection frame 100 and the probe module 300.

[0042] Next, please refer to the following: Figure 5 and Figure 6 , Figure 5 This is a three-dimensional schematic diagram of the probe module according to the second embodiment of the present invention. Figure 6 This is a partial cross-sectional schematic diagram of the probe module according to the second embodiment of the present invention.

[0043] In the second embodiment, the first upper connecting group 310 includes: a first floating connecting seat 311', a first extension sheet 313', a plurality of first pins 314', a first fixing unit 315', two first elastic supports 316', a support portion 3111', a contact segment 3141', a first bending portion 3131', and a second bending portion 3132'; on the other hand, the second upper connecting group 320 includes: a second floating connecting seat 321', a second extension sheet 323', a plurality of second pins 324', a second fixing unit 325', two second elastic supports 326', a support portion 3211', a contact segment 3241', a first bending portion 3231', and a second bending portion 3232'. The front surfaces of the first floating connecting seat 311' and the second floating connecting seat 321' are configured to face each other.

[0044] The first pin 314' is disposed on the first floating connector 311', and has a contact section 3141' exposed on the top surface of the first floating connector 311'. The contact section is used to abut against the first electrode area 110 of the battery test holder 100 (which can be used simultaneously). Figure 2 The ends of each first pin 314' opposite to the contact segment 3141' are used to couple to the first extension piece 313'. For example, the first pin 314' can be indirectly electrically connected to the first extension piece 313' via solder or the first pin 314' can be directly electrically connected to the first extension piece 313'.

[0045] like Figure 6 As shown, the first extension piece 313' is configured to extend from the upper surface of the first polar piece 301, and can extend in the direction of the second polar piece 302 through the first bend 3131' and extend below the first suspension connector 311', and further extend to the front of the first suspension connector 311' through the second bend 3132'.

[0046] The first fixing unit 315' penetrates the first extension plate 313' and fixes one end of the first extension plate 313' to the front of the first suspension connector 311'. The first suspension connector 311' has a support portion 3111' extending from each side. One end of each first elastic support member 316' penetrates the first polarity plate 301 and is disposed in the seat 303, and the other end of each first elastic support member 316' is disposed in the first suspension connector 311', thereby providing support for the first suspension connector 311'. In addition, each first elastic support member 316' is used to withstand the external force from the first electrode area 110 of the battery detection holder 100 when the first suspension connector 311' is subjected to external force (which can be used in conjunction with) Figure 2 It provides a restoring force to increase the stability of the electrical connection between the contact segment 3141' of the first pin 314' and the first electrode region 110.

[0047] In the second embodiment, the configuration of the second upper connection group 320 is similar to that of the first upper connection group 310, and the second upper connection group 320 will not be described in detail here.

[0048] In addition, such as Figure 5 and Figure 6 As shown, the position where the first lower connector 319 is coupled to the first polar plate 301 is different from the position where the first extension plate 313' is coupled to the first polar plate 301. When the first lower connector 319 is abutted, it will not affect the contact segment 3141' of the first pin 314' used to abut the first electrode area 110 of the battery test holder 100 (which can be used simultaneously). Figure 2(For reference). Also, the position where the second lower connector 329 is coupled to the second polarity plate 302 is different from the position where the second extension plate 323' is coupled to the second polarity plate 302. When the second lower connector 329 is abutted, it will not affect the contact segment 3241' of the second pin 324' used to abut the second electrode region 120 of the battery testing holder 100 (which can be used simultaneously). Figure 2 (For reference).

[0049] Next, please refer to the following: Figure 7 and Figure 8 , Figure 7 This is a three-dimensional schematic diagram of the probe module according to the third embodiment of the present invention. Figure 8 This is a partial cross-sectional schematic diagram of the probe module according to the third embodiment of the present invention.

[0050] Can be paired with Figure 2 In comparison, in the third embodiment, the battery testing rack 100 is provided with a first plug-in piece 111 serving as a first electrode region 110 and a second plug-in piece 121 serving as a second electrode region 120.

[0051] The first upper connection group 310 includes: a first connecting seat 311”, a first fixing unit 315”, a first clamping piece 317”, a plurality of first pins 314”, a first slot 318”, and a contact section 3141”; on the other hand, the second upper connection group 320 includes: a second connecting seat 321”, a second fixing unit 325”, a second clamping piece 327”, a plurality of second pins 324”, a first slot 328”, and a contact section 3241”.

[0052] like Figure 7 and Figure 8 As shown, the first connecting seat 311” is disposed on the upper surface of the first polar plate 301. The first clamping piece 317” is fixed to the first connecting seat 311” by the first fixing unit 315” and is located on the front side of the first connecting seat 311”. In addition, by matching the relative positions of the first clamping piece 317” and the first connecting seat 311”, a gap can be formed between the first clamping piece 317” and the first connecting seat 311”, which forms the first slot 318” for the insertion of the first insert piece 111. The upper section of the first clamping piece 317” may also be provided with an inclined portion with a guiding function to facilitate the correct insertion of the first insert piece 111 into the first slot 318”.

[0053] The first pin 314” is disposed on the first connector 311” and has a contact segment 3141” protruding from the front of the first connector 311”. The contact segment 3141” of each first pin 314” is used to abut against the first plug piece 111 inserted into the first slot 318”. The end of each first pin 314” opposite to the contact segment 3141” is used to couple to the first polarity plate 301. For example, the first pin 314” can be indirectly electrically connected to the first polarity plate 301 by solder or directly electrically connected to the first polarity plate 301.

[0054] Therefore, when the probe module 300 is placed on the battery testing rack 100, the first connector 111 will be inserted into the first slot 318”, forming a coupling relationship between the first connector 111 and the first polarity plate 301 for subsequent testing procedures.

[0055] In the third embodiment, the configuration of the second upper connection group 320 is similar to that of the first upper connection group 310, and the second upper connection group 320 will not be described in detail here.

[0056] In addition, such as Figure 7 and Figure 8 As shown, the position of the first lower connector 319 coupled to the first polarity plate 301 is different from the position of each first pin 314” coupled to the first polarity plate 301. When the first lower connector 319 is abutted, it will not affect the contact segment 3141” of the first pin 314” used to abut the first plug piece 111. Similarly, the position of the second lower connector 329 coupled to the second polarity plate 302 is different from the position of the second pin 324” coupled to the second polarity plate 302. When the second lower connector 329 is abutted, it will not affect the contact segment 3241” of the second pin 324” used to abut the second plug piece 121.

[0057] Next, please refer to Figure 9 This is a schematic diagram of a polarized sheet on a probe module according to an embodiment of the present invention. The second polarized sheet 302 has two encircling portions 3021 and 3022 extending toward both sides of the base 303 on the upper surface of the base 303. These two encircling portions 3021 and 3022 surround a portion of the first polarized sheet 301.
