Technical Field

[0001] The embodiments of the present application relate to the field of connector technology, and in particular to a connector device and an electronic device. Background Art

[0002] With the advancement of science and technology, electronic products such as mobile phones, tablets, computers, monitors, and smart wearable devices are significantly improving people's quality of life and bringing more and more convenience in more and more aspects. Electronic products often have connectors such as USB ports and Type-C ports to facilitate the transmission of electrical signals between electronic products and the outside world.

[0003] Although connectors in the prior art control arc generation during plugging and unplugging by controlling the length of the terminals, arc generation still occurs during rapid plugging and unplugging of the connectors due to limitations on the length of the terminals, posing a risk of damage to the safety and performance of electronic products. Utility Model Content

[0004] The main technical problem solved by the embodiments of the present application is to provide a connector device and an electronic device, which can effectively solve the problem of arcing generated during the rapid plugging and unplugging of the connector and improve its safety performance.

The middle clamping plate includes a first part and a second part that are separated from each other. The first detection terminal is arranged on the first part through the first base. The first detection terminal and the second part are connected in series on the first circuit board. The second connector includes a second base, a second detection terminal, a first clamping arm, and a second circuit board. The second detection terminal is arranged on the second base. The first clamping arm is arranged on the side of the second base. The second detection terminal and the first clamping arm are connected in series on the second circuit board. The first detection terminal is used to electrically connect to the second detection terminal, and the second part is used to electrically connect to the first clamping arm, so that the first connector and the second connector form a detection circuit.

[0006] In some embodiments, when the first connector and the second connector are plugged in, the connection between the first detection terminal and the second detection terminal occurs before the connection between the second part and the first clamping arm; when the first connector and the second connector are separated, the separation of the second part and the first clamping arm occurs before the separation of the first detection terminal and the second detection terminal.

[0007] In some embodiments, along the plugging direction of the first connector and the second connector, when the first detection terminal and the second detection terminal are in contact, the spacing distance D1 between the first clamping arm and the second portion satisfies: 0.3 mm ≤ D1 ≤ 0.7 mm; when the first clamping arm and the second portion are in contact, the overlapping distance D2 between the first detection terminal and the second detection terminal satisfies: 0.3 mm ≤ D2 ≤ 0.7 mm.

[0008] In some embodiments, the first connector further includes a third detection terminal. Along the thickness direction of the first base, the first detection terminal and the third detection terminal are respectively located on both sides of the first part. After the first detection terminal and the third detection terminal are connected in parallel on the first circuit board, they are connected in series with the second part.

[0009] In some embodiments, the second connector also includes a fourth detection terminal. Along the thickness direction of the second base, the second detection terminal and the fourth detection terminal are respectively located on both sides of the second base. After the second detection terminal and the fourth detection terminal are connected in parallel on the second circuit board, they are connected in series with the first clamping arm.

[0010] In some embodiments, the second connector also includes a second clip arm, and the second clip arm and the first clip arm are respectively arranged on both sides of the second base along its width direction, and the width direction of the second base is perpendicular to the thickness direction of the second base; the first clip arm and the second clip arm are connected in parallel on the second circuit board, and one of the first clip arm and the second clip arm is plugged into the second part, so that the first connector and the second connector can form a detection loop.

[0011] In some embodiments, the first detection terminal may be electrically connected to one of the second detection terminal and the fourth detection terminal, and the third detection terminal may be electrically connected to the other of the second detection terminal and the fourth detection terminal.

[0012] In some embodiments, the first connector further includes a first ground terminal electrically connected to the second portion.

[0013] In some embodiments, the first snap-fit arm is provided with a first snap-fit portion, the first part is provided with a second snap-fit portion, and the first snap-fit portion is used to snap-fit and connect with the second snap-fit portion; and / or, the first connector also includes a first shell, and the first shell is grounded to the first part.

[0014] Another technical solution adopted in an embodiment of the present application is: providing an electronic device including a connector device.

[0015] The beneficial effects of the embodiments of the present application are as follows: the connector device of the embodiment of the present application sets the middle clamping plate of the first connector into a first part and a second part that are separated from each other, and the second part and the first detection terminal are connected in series on the first circuit board. At the same time, the first clamping arm and the second detection terminal of the second connector are connected in series on the second circuit board. When the first connector and the second connector are plugged in, the first detection terminal and the second detection terminal are connected, and the second part is connected to the first clamping arm. In this way, compared with the structure in which only the first detection terminal and the second detection terminal constitute a switch, the above-mentioned structure of the present application further adds a second switch structure consisting of the second part and the first clamping arm, and the two switches are set in series, that is, only when the first detection terminal and the second detection terminal are connected and the second part and the first clamping arm are also connected, will the power-on signal be triggered, so that the first connector and the second connector are powered on. The structure of the second part and the first clamping arm connected in the present application can effectively prolong the reaction time of power on and off, thereby effectively preventing the arc phenomenon during the process of rapid plugging or separation, and improving the safety performance of the connector device.

[0024] In order to facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that when an element is described as being "fixed on" another element, it can be directly on the other element, or there can be one or more centered elements therebetween. When an element is described as being "connected to" another element, it can be directly connected to the other element, or there can be one or more centered elements therebetween. The terms "upper", "lower", "inside", "outside", "vertical", "horizontal", etc. used in this specification indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0025] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the relevant listed items.

[0026] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0027] A connector assembly typically includes two connectors, such as a plug connector and a receptacle connector. For example, the plug connector is attached to a data cable, while the receptacle connector is attached to an electronic device such as a mobile phone or computer. These two connectors enable functions such as charging and data transmission. When the plug and receptacle connectors are quickly connected or disconnected, arcing can occur during the instantaneous power on or off, potentially degrading the performance of the plug and receptacle connectors.

[0028] To prevent arcing, the prior art typically designs detection terminals in the socket and plug connectors. By controlling the length of the detection terminals to be shorter than the length of the power terminals, when the socket and plug connectors are plugged together, the power terminals are connected first, followed by the detection terminals, which trigger a power-on signal. At this point, the two connectors are electrically connected. When the socket and plug connectors are separated, the detection terminals are disconnected first and trigger a power-off signal. At this point, the two connectors are powered off, followed by the power terminals. This allows the socket and plug connectors to be powered on only after they are safely plugged together, and to be powered off before being safely separated. However, the user's actions of plugging or unplugging connectors are milliseconds, and due to the connector's size, the length of the detection terminals on the connectors is relatively small compared to the length of the power terminals. Consequently, the reaction time between powering on and off during the plugging and unplugging process is very short, making it impossible to effectively prevent arcing.

[0029] Based on the above problems, the present application provides a connector device, which divides the middle plate of the socket connector into two separate parts, one of which retains the original function of the middle plate to isolate and shield the upper and lower terminals from interfering with each other, and the other part, in addition to having the isolation and shielding functions, is also connected in series with the detection terminal. Since the middle plate of this part can form a significant length difference with the power terminal, the reaction time of power on and off is effectively extended, thereby preventing the occurrence of arcing.

[0030] See also Figures 1 to 4 The embodiment of the present application provides a connector device 100, which includes a first connector 10 and a second connector 20. The first connector 10 and the second connector 20 can be plugged in or separated along the length direction X. The first connector 10 includes a first base 11, a first terminal group 12, a middle clamping plate 13 and a first circuit board 14. Figure 4 The first terminal group 12 includes a first detection terminal 121, a first power terminal 122, and a plurality of first signal terminals 125. The middle clamping plate 13 is disposed on the first base 11. The middle clamping plate 13 includes a first portion 131 and a second portion 132 that are separated from each other. The first detection terminal 121 and the first power terminal 122 are correspondingly disposed on the first portion 131 through the first base 11. The first detection terminal 121 and the second portion 132 are connected in series on the first circuit board 14. The first power terminal 122 and the first signal terminal 125 are both electrically connected to the first circuit board 14.

[0031] The second connector 20 includes a second base 21, a second terminal group 22, a first clamping arm 23, and a second circuit board 24, wherein the second terminal group 22 includes a second detection terminal 221, a second power terminal 222, and a second signal terminal 224. The second detection terminal 221, the second power terminal 222, and the second signal terminal 224 are all arranged on the second base 21. The first clamping arm 23 is arranged on the side of the second base 21 along its width direction Y. The second detection terminal 221 and the first clamping arm 23 are connected in series on the second circuit board 24. The second power terminal 222 and the second signal terminal 224 are both electrically connected to the second circuit board 24. The first detection terminal 121 is used to electrically connect to the second detection terminal 221, and the second part 132 is used to electrically connect to the first clamping arm 23, so that the first connector 10 and the second connector 20 form a detection circuit of "first detection terminal 121-second detection terminal 221-first clamping arm 23-second part 132" (such as Figure 6 The first power terminal 122 is used to connect to the second power terminal 222, thereby electrically connecting the first connector 10 and the second connector 20 for power transmission. The first signal terminal 125 is used to connect to the second signal terminal 224, thereby electrically connecting the first connector 10 and the second connector 20 for data transmission.

[0032] The connector device 100 of the embodiment of the present application sets the middle clamping plate 13 of the first connector 10 into a first part 131 and a second part 132 that are separated from each other, and the second part 132 and the first detection terminal 121 are connected in series on the first circuit board 14. At the same time, the first clamping arm 23 and the second detection terminal 221 of the second connector 20 are connected in series on the second circuit board 24. When the first connector 10 and the second connector 20 are plugged in, the first detection terminal 121 and the second detection terminal 221 are connected, and the second part 132 and the first clamping arm 23 are connected to form a detection circuit. Figure 6 Compared to the prior art detection circuit structure in which only the first detection terminal 121 and the second detection terminal 221 form a switch K1, the structure of the present application further adds a second switch K2 formed by the second portion 132 and the first clamping arm 23. The two switches K1 and K2 are arranged in series. That is, only when the first detection terminal 121 and the second detection terminal 221 are connected and the second portion 132 and the first clamping arm 23 are also connected will the detection circuit trigger the power-on signal, conductively connecting the first power terminal 122 and the second power terminal 222, thereby energizing the first connector 10 and the second connector 20. The structure in which the second portion 132 and the first clamping arm 23 are connected in the present application can effectively extend the response time of power on and off, thereby effectively preventing arcing during rapid plugging and unplugging, and improving the safety performance of the connector device 100.

[0033] It is worth noting that the length direction X, width direction Y and thickness direction Z described in this application can be applied to any component, and the length direction X, width direction Y and thickness direction Z are perpendicular to each other.

[0034] In some embodiments, see Figure 4 and Figure 5 When the first connector 10 and the second connector 20 are plugged together along the length direction X, the connection between the first detection terminal 121 and the second detection terminal 221 occurs first before the connection between the second portion 132 and the first clamping arm 23. Figure 5 In the first connector 10, with the first detection terminal 121 extending from the first base 11 as the starting reference, along the length direction X of the first base 11, the exposed length L2 of the first detection terminal 121 is shorter than the exposed length L1 of the first power terminal 122, and the exposed length L3 of the second portion 132 of the middle clamping plate 13 is shorter than the exposed length L2 of the first detection terminal 121; and in the second connector 20, with the second detection terminal 221 extending from the second base 21 as the starting reference, the exposed length L4 of the second detection terminal 221 and the exposed length L5 of the second power terminal 222 are shorter than the exposed length L1 of the first detection terminal 121. The first portion 132 and the second portion 133 are almost equal, and the extended length L6 of the first clamping arm 23 is almost equal to the exposed length L4 of the second detection terminal 221, or the extended length L6 of the first clamping arm 23 is shorter than the exposed length L4 of the second detection terminal 221. Therefore, during the plugging process of the first connector 10 and the second connector 20, the first power terminal 122 and the second power terminal 222 are first contacted and connected, then the first detection terminal 121 and the second detection terminal 221 are contacted and connected, and finally the second portion 132 and the first clamping arm 23 are contacted and connected. At this point, the detection circuit is closed, thereby triggering the power-on signal.

[0035] Through the above structure setting, combined with Figure 6 After the first power terminal 122 and the second power terminal 222 of the present application are connected, the first switch K1 formed by the first detection terminal 121 and the second detection terminal 221, and the second switch K2 formed by the second portion 132 and the first clamping arm 23 must be closed in sequence before the power-on signal can be triggered. In this way, the reaction time from physical connection to electrical connection between the first power terminal 122 and the second power terminal 222 can be greatly extended, avoiding the occurrence of arcing when the first connector 10 and the second connector 20 are plugged in. It is worth noting that the physical connection between the first power terminal 122 and the second power terminal 222 means that the two are only in contact with each other, and no electrical connection is formed between them.

[0036] When the first connector 10 and the second connector 20 are separated, the second portion 132 and the first clamping arm 23 separate before the first detection terminal 121 and the second detection terminal 221 separate. Specifically, the second switch K2 formed by the second portion 132 and the first clamping arm 23 opens first, triggering a power-off signal, de-energizing the first power terminal 122 and the second power terminal 222. The first switch K1 formed by the first detection terminal 121 and the second detection terminal 221 then opens, ultimately separating the first power terminal 122 and the second power terminal 222 while still de-energized. This significantly shortens the reaction time from de-energization to separation of the first power terminal 122 and the second power terminal 222, thus preventing arcing when the first connector 10 and the second connector 20 separate.

[0037] In further embodiments, see Figure 5 In the length direction X of the first connector 10, with the point where the first detection terminal 121 extends from the first base 11 as the starting point, the exposed length L2 of the first detection terminal 121 is approximately 0.5±0.2 mm shorter than the exposed length L1 of the first power terminal 122. Furthermore, the exposed length L3 of the second portion 132 of the middle clamping plate 13 is approximately 0.5±0.2 mm shorter than the exposed length L2 of the first detection terminal 121. Consequently, the exposed length L3 of the second portion 132 is approximately 1±0.4 mm shorter than the exposed length L1 of the first power terminal 122.

[0038] When the first connector 10 and the second connector 20 are plugged in and the first power terminal 122 and the second power terminal 222 are just in contact, along the length direction X, the distance between the first detection terminal 121 and the second detection terminal 221 is approximately 0.5±0.2 mm, and the distance between the second portion 132 and the first clamping arm 23 is approximately 1±0.4 mm.

[0039] When the first connector 10 and the second connector 20 continue to be plugged in and the first detection terminal 121 and the second detection terminal 221 are just in contact, the overlap length between the first power terminal 122 and the second power terminal 222 is approximately 0.5±0.2mm, and the distance D1 between the first clamping arm 23 and the second portion 132 satisfies: 0.3mm≤D1≤0.7mm.

[0040] When the first connector 10 and the second connector 20 are further plugged in and the second portion 132 and the first clamping arm 23 are just in contact, the overlapping distance D2 between the first detection terminal 121 and the second detection terminal 221 satisfies: 0.3mm≤D2≤0.7mm, and the overlapping length between the first power terminal 122 and the second power terminal 222 is approximately 1±0.4mm.

[0041] It is worth noting that the spacing distance D1 between the first clamping arm 23 and the second part 132 refers to the spacing distance between the portion of the first clamping arm 23 used to abut against the second part 132 and the end of the second part 132 close to the second connector 20. For example, when the first clamping arm 23 is provided with a first snap-fit portion 231 or a first abutting portion, the spacing distance D1 refers to the distance between the first snap-fit portion 231 or the first abutting portion and the end of the second part 132.

[0042] Through the above-described structural arrangement, when the first power terminal 122 and the second power terminal 222 are in contact, the distance between the first snap arm 23 and the second portion 132 is at least 1±0.4 mm. This exponential increase in distance doubles the power-on response time when the first connector 10 and the second connector 20 are plugged together. Furthermore, when the first snap arm 23 and the second portion 132 are in contact, the overlapping distance D2 between the first detection terminal 121 and the second detection terminal 221 satisfies the following: 0.3 mm ≤ D2 ≤ 0.7 mm. In this case, the overlapping distance between the first power terminal 122 and the second power terminal 222 is at least 1±0.4 mm. In other words, the above-described structure ensures that when the first power terminal 122 and the second power terminal 222 are securely plugged together, the contact between the first snap arm 23 and the second portion 132 triggers a power-on signal, thereby electrically connecting the first power terminal 122 and the second power terminal 222.

[0043] During the process of separation of the first connector 10 and the second connector 20, when the first clamping arm 23 and the second part 132 are just separated and the power-off signal is triggered, the overlapping distance between the first power terminal 122 and the second power terminal 222 is at least 1±0.4mm. In this way, the reaction time of the first power terminal 122 and the second power terminal 222 from power off to physical separation is multiplied, so that the first power terminal 122 and the second power terminal 222 can be separated in the power-off state, effectively preventing the occurrence of arcing.

[0044] In some embodiments, see Figure 6The first connector 10 also includes a third detection terminal 123. Along the thickness direction Z of the first base 11, the first detection terminal 121 and the third detection terminal 123 are centrally symmetrically located on either side of the first portion 131, respectively. This ensures both forward and reverse insertion of the first connector 10 into the second connector 20. After being connected in parallel on the first circuit board 14, the first detection terminal 121 and the third detection terminal 123 are connected in series with the second portion 132. The structure in which the first detection terminal 121 and the third detection terminal 123 are respectively located on either side of the first portion 131 and connected in parallel allows the second detection terminal 221 to connect to the first detection terminal 121 when the second connector 20 is plugged into the first connector 10 from the front, and the second detection terminal 221 to connect to the third detection terminal 123 when the second connector 20 is plugged into the first connector 10 from the back. In other words, regardless of whether the first connector 10 and the second connector 20 are plugged into the front or back, the detection terminals can be connected, thereby closing the first switch in the circuit loop.

[0045] In some embodiments, see Figure 6 The second connector 20 further includes a fourth detection terminal 223. Along the thickness direction Z of the second base 21, the second detection terminal 221 and the fourth detection terminal 223 are symmetrically located on both sides of the second base 21 to meet the requirements of both forward and reverse insertion of the first connector 10 and the second connector 20. After the second detection terminal 221 and the fourth detection terminal 223 are connected in parallel on the second circuit board 24, they are connected in series with the first clamping arm 23. Through the above structure, when the second connector 20 is plugged into the first connector 10 from the front, the first detection terminal 121 is connected to the second detection terminal 221, or the third detection terminal 123 is connected to the fourth detection terminal 223. Only one of these two situations or both situations need to be realized to close the first switch in the circuit loop. Similarly, when the second connector 20 is plugged into the first connector 10 from the reverse side, the first detection terminal 121 is connected to the fourth detection terminal 223, or the second detection terminal 221 is connected to the third detection terminal 123. Only one of these two situations needs to be realized, or both situations need to be realized, and the first switch in the circuit loop can also be closed.

[0046] In some embodiments, see Figure 4The second connector 20 further includes a second snap-fitting arm 25. The second snap-fitting arm 25 and the first snap-fitting arm 23 are respectively disposed on either side of the second base 21 along its width direction Y, wherein the width direction Y of the second base 21 is perpendicular to the thickness direction Z of the second base 21. The first snap-fitting arm 23 and the second snap-fitting arm 25 are connected in parallel on the second circuit board 24. When one of the first snap-fitting arm 23 and the second snap-fitting arm 25 is plugged into the second portion 132, a detection loop is formed between the first connector 10 and the second connector 20. Since the second part 132 of the middle clamping plate 13 is arranged on one of the side parts of the first part 131, the first clamping arm 23 needs to be located on the same side as the second part 132 to achieve plug-in connection. When the second connector 20 has a first clamping arm 23 and a second clamping arm 25 respectively located on both sides and the two are arranged in parallel, when the second connector 20 is plugged into the first connector 10 from the front, the first clamping arm 23 and the second part 132 are connected to close the second switch K2. When the second connector 20 is plugged into the first connector 10 from the back, the second clamping arm 25 and the second part 132 are connected to close the second switch K2.

[0047] In some embodiments, see Figure 7 The first snap-fitting portion 231 is provided on the side of the first clamping arm 23 facing the first portion 131. A second snap-fitting portion 1311 is provided at the end of the first portion 131 near the second connector 20 along the length direction X of the first portion 131. The second snap-fitting portion 1311 protrudes along the width direction Y of the first portion 131. The first snap-fitting portion 231 is configured to snap-fit with the second snap-fitting portion 1311. It is understood that in some embodiments, the size of the first snap-fitting portion 231 is sufficiently large so that while the first snap-fitting portion 231 and the second snap-fitting portion 1311 are snap-fitted together, the first snap-fitting portion 231 can also abut against the second portion 132 of the middle clamping plate 13. In other words, the first snap-fitting portion 231 not only has the function of snapping and fixing to prevent the first connector 10 and the second connector 20 from falling off naturally, but also has the function of electrically connecting the second portion 132, allowing the detection circuit to be turned on, thereby triggering the power-on signal. In other embodiments, when the distance between the second snap-fitting portion 1311 on the first part 131 and the second part 132 is large, a first abutting portion may also be provided on the first clamping arm 23, and the first abutting portion is located at one end of the first snap-fitting portion 231 close to the first connector 10. At this time, the first snap-fitting portion 231 is used to snap-fit and connect with the second snap-fitting portion 1311, and the first abutting portion is used to contact and electrically connect with the second part 132.

[0048] In some embodiments, see Figure 4The first terminal group 12 of the first connector 10 further includes a first grounding terminal 124. The first grounding terminal 124 is disposed on the first base 11 in correspondence with the second portion 132 of the middle clamping plate 13, and the first grounding terminal 124 is electrically connected to the second portion 132. By electrically connecting the first grounding terminal 124 to the second portion 132, the second portion 132 is also grounded, thereby enhancing the shielding performance of the second portion 132 and thus enhancing the anti-crosstalk capability of the second portion 132.

[0049] In some embodiments, see Figure 2 The first connector 10 further includes a first housing 15, which is grounded to the first portion 131. The first housing 15 is a metal shell. Grounding the first housing 15 to the first portion 131 can, on the one hand, enhance the shielding performance of the first portion 131, thereby enhancing the anti-crosstalk capability of the first portion 131; on the other hand, it can shorten the grounding path of the first portion 131, thereby allowing interference signals (abnormal current) to be transmitted to the outside world more quickly, thereby improving the data transmission performance between the first connector 10 and the second connector 20.

[0050] The present application further provides an embodiment of an electronic device, which includes the above-mentioned connector device 100. The specific structure and function of the connector device 100 can be found in the above-mentioned embodiment and will not be described in detail here.

[0051] In the connector device 100 of the present embodiment, the center plate 13 of the first connector 10 is configured into a separate first portion 131 and a second portion 132. The second portion 132 and the first detection terminal 121 are connected in series on the first circuit board 14. Simultaneously, the first snap-fit arm 23 and the second detection terminal 221 of the second connector 20 are connected in series on the second circuit board 24. When the first connector 10 and the second connector 20 are plugged in, the first detection terminal 121 and the second detection terminal 221 are connected, and the second portion 132 is connected to the first snap-fit arm 23. Thus, compared to a structure in which only the first detection terminal 121 and the second detection terminal 221 form a single switch, the aforementioned structure of the present application also adds a second switch formed by the second portion 132 and the first snap-fit arm 23. These two switches are arranged in series. That is, the power-on signal is triggered only when the first detection terminal 121 and the second detection terminal 221 are connected, and the second portion 132 and the first snap-fit arm 23 are also connected, thereby energizing the first connector 10 and the second connector 20. The structure of connecting the second part 132 and the first clamping arm 23 provided in the present application can effectively extend the reaction time of power on and off, thereby effectively preventing arcing during rapid plugging or separation, and improving the safety performance of the connector device 100.

[0052] The above description is merely an embodiment of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
