Abstract
Description
Technical Field
[0001] This application relates to the field of signal transmission technology, and in particular to a male connector, a female connector, and a connector assembly. Background Technology
[0002] In the prior art, Pogo pin connectors (spring probe connectors) can provide pre-pressure to the metal probe through a spring, enabling the spring probe connector to maintain stable contact performance even when subjected to external force. Therefore, Pogo pin connectors are widely used in consumer electronics products such as mobile phones, tablets, and wearable devices to realize functions such as battery connection, charging, and data transmission.
[0003] However, because Pogo pin connectors typically contain multiple closely spaced pins, these pins are prone to electromagnetic coupling. When a high-frequency signal passes through a pin, it may affect adjacent pins through electromagnetic coupling, resulting in crosstalk. Consequently, Pogo pin connectors are generally unable to transmit high-speed signals. Utility Model Content

[0048] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.
[0049] To address the technical problem that existing spring probe connectors cannot be used for high-speed signal transmission due to high-frequency signal crosstalk, this application provides a male connector, a female connector, and a connector assembly. The male connector has a first groove 211 on the side wall of the communication probe holding hole 21, which creates an air gap between the outer wall of the spring probe 1 used for signal transmission and the inner wall of the communication probe holding hole 21. This increases impedance and reduces energy loss. The high impedance and low loss characteristics result in less signal attenuation and lower waveform distortion during transmission, reducing the impact of crosstalk on the quality of high-frequency signals. This allows the male connector and the connector assembly with the male connector to meet the requirements of high-speed data transmission.
[0050] Please see Figures 1 to 10 The first aspect of this application provides a male connector, including spring probes 1 and a first connector body 2. The number of spring probes 1 is multiple, and each spring probe 1 includes a metal probe 11, a conductive ball 12, an elastic element 13, and a metal sleeve 14, all made of metal material, and can be used to realize signal and current transmission. Multiple spring probes 1 can simultaneously connect to multiple contacts or circuits, and different spring probes 1 can be assigned to different signal types, such as power, ground, data transmission, and control signals, which can be used to achieve multi-point electrical conduction between devices.
[0051] The first connector body 2 serves as a fixing base for multiple spring probes 1. It is typically made of insulating material (such as plastic) to effectively isolate electrical interference between the spring probes 1 and avoid short-circuit risks. Figure 1 As shown.
[0052] The first connector body 2 is provided with multiple communication probe holding holes 21 and multiple functional probe holding holes 22; each of the multiple communication probe holding holes 21 and multiple functional probe holding holes 22 is provided with a spring probe 1, such as Figures 1 to 4 As shown. Among them, the spring probe 1 set in the communication probe holding hole 21 can be used to realize the data transmission function, and the spring probe 1 set in the functional probe holding hole 22 can be used to realize other key functions, such as grounding, obtaining power, connection detection, etc.
[0053] A first groove 211 is formed on the side wall of the communication probe holding hole 21, which allows an air gap to be formed between the outer wall of the spring probe 1 used for signal transmission and the inner wall of the communication probe holding hole 21. Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown. On the one hand, since the dielectric constant of the air gap is much smaller than that of the solid insulating material (i.e., the manufacturing material of the first connector body 2), and capacitance is directly proportional to dielectric constant while capacitive reactance is inversely proportional to capacitance, the dielectric constant of the slotted area around the spring probe 1 can be reduced by opening the first groove 211. The reduced capacitance can increase the capacitive reactance, thereby increasing the total impedance. On the other hand, since the dielectric loss of air is also much smaller than that of solid insulating material, the presence of the air gap can significantly reduce the energy loss of high-frequency signals in the dielectric. The characteristics of high impedance and low loss result in less signal attenuation and lower waveform distortion during transmission, reducing the impact of crosstalk on the quality of high-frequency signals. This allows the male connector and the connector assembly with the male connector to meet the requirements of high-speed data transmission.
[0054] In some embodiments of this application, please refer to Figure 2 , Figure 6 and Figure 7 The first groove 211 extends axially along the communication probe holding hole 21, which can form a relatively uniform air gap along the axial direction of the spring probe 1, so that the axially extended air gap forms a uniform low dielectric constant dielectric layer, and maintains a consistent impedance characteristic along the entire length of the spring probe 1.
[0055] In some embodiments of this application, please refer to Figure 3 and Figure 4 The functional probe holding hole 22 is a countersunk hole, and the communication probe holding hole 21 is provided with a limiting countersunk 212 inside, both of which can be used to achieve limiting cooperation with the metal sleeve 14 of the spring probe 1.
[0056] In some embodiments of this application, please refer to Figure 2 and Figure 3The multiple communication probe holding holes 21 include multiple sets of signal hole pairs. Each set of signal hole pairs includes two communication probe holding holes 21 arranged side by side along a first direction. The two spring probes 1 arranged in the same set of signal hole pairs can be used to transmit and receive data, respectively. The first groove 211 is arranged on both sides of the communication probe holding holes 21 in the first direction, which can avoid crosstalk between the two spring probes 1 arranged in the same set of signal hole pairs when transmitting and receiving high-frequency signals.
[0057] As a specific embodiment of this application, please refer to Figure 2 The first direction is Figure 2 In the left and right direction, the communication probe holding hole 21 has a first groove 211 on both the left and right sides, which can form two air gaps between the same group of signal holes, thus avoiding crosstalk between the two spring probes 1 set in the same group of signal holes when sending and receiving high-frequency signals.
[0058] In some embodiments of this application, please refer to Figure 2 The alternating arrangement of multiple signal hole pairs and multiple functional probe holding holes 22 can avoid the concentration of multiple signal hole pairs on the first connector body 2. The functional probe holding holes 22 form isolation between adjacent signal hole pairs, thus avoiding crosstalk between the four spring probes 1 in two adjacent signal hole pairs.
[0059] As a specific embodiment of this application, please refer to Figure 2 When the first connector body 2 has 6 sets of signal hole pairs, in Figure 2 In the left-right direction, three sets of signal apertures are alternately spaced with four functional probe holding apertures 22. Figure 2 In the vertical direction, two sets of signal hole pairs are alternately spaced with a functional probe holding hole 22, thereby avoiding multiple sets of signal hole pairs being concentrated on the first connector body 2.
[0060] In some embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 3 Multiple spring probes 1 are arranged in a matrix on the first connector body 2, that is, in the form of M rows × N columns, where M and N are both positive integers greater than 1. This maximizes the utilization of the surface space of the first connector body 2 and reduces the volume occupied. Furthermore, a first spacing is formed between two adjacent spring probes 1 in each row, and a second spacing is formed between two adjacent spring probes 1 in each column. By setting the spacing appropriately, better impedance characteristics can be obtained.
[0061] Please refer to some preferred embodiments of this application. Figure 2 and Figure 5The first spacing between two adjacent spring probes 1 in each row is 2-2.5 mm, and the second spacing between two adjacent spring probes 1 in each column is 2-3 mm.
[0062] In some embodiments of this application, please refer to Figure 2 and Figure 5 Multiple communication probe holding holes 21 are arranged symmetrically on the first connector body 2; multiple functional probe holding holes 22 are arranged symmetrically on the first connector body 2, which is conducive to realizing the positive and negative insertion of the male connector, so that the male connector can achieve accurate electrical connection with the female connector whether it is inserted positively or negatively.
[0063] In some embodiments of this application, the communication probe holding hole 21 includes a transmission probe holding hole, a receiving probe holding hole, and a signal detection probe holding hole. The spring probe 1 disposed in the transmission probe holding hole is used to transmit data, the spring probe 1 disposed in the receiving probe holding hole is used to receive data, and the spring probe 1 disposed in the signal detection probe holding hole is used to perform signal detection, thereby improving signal integrity and transmission reliability.
[0064] In some embodiments of this application, the spring probe 1 disposed in the transmission probe holding hole is defined as the TX terminal, the spring probe 1 disposed in the receiving probe holding hole is defined as the RX terminal, and the spring probe 1 disposed in the signal detection probe holding hole is defined as the DD terminal.
[0065] In some embodiments of this application, the functional probe holding hole 22 includes a ground probe holding hole, a power probe holding hole, an auxiliary probe holding hole, and a configuration channel probe holding hole. The spring probe 1 disposed in the ground probe holding hole is used to provide a ground reference point for the circuit. The spring probe 1 disposed in the power probe holding hole is used to provide the power required by the device. The spring probe 1 disposed in the auxiliary probe holding hole is used for other auxiliary functions or as a spare signal line. The spring probe 1 disposed in the configuration channel probe holding hole is used for connection detection.
[0066] As a specific embodiment of this application, when the first connector is provided with 30 spring probes 1, the pin-out method of the male connector (i.e., the method of defining the pin arrangement and function of the connector) is shown in Table 1 below:
[0067] Table 1: Pin Out Methods of Male Connectors
[0068]
[0069] The male connector has six pairs of signal holes (i.e., twelve communication probe holding holes 21). The first pair is the communication probe holding holes 21 corresponding to TX1+ and TX1- (specifically, transmission probe holding holes). The second pair is the communication probe holding holes 21 corresponding to DD1+ and DD1- (specifically, signal detection probe holding holes). The third pair is the communication probe holding holes 21 corresponding to RX2+ and RX2- (specifically, receive probe holding holes). The fourth pair is the communication probe holding holes 21 corresponding to RX1+ and RX1- (specifically, receive probe holding holes). The fifth pair is the communication probe holding holes 21 corresponding to DD2+ and DD2- (specifically, signal detection probe holding holes). The sixth pair is the communication probe holding holes 21 corresponding to TX2+ and TX2- (specifically, transmission probe holding holes).
[0070] The twelve spring probes 1 in the six signal hole pairs are centrally symmetrically arranged on the first connector body 2; among them, TX1+ and TX2+ are centrally symmetrically arranged and are both positive terminals for data transmission, while TX1- and TX2- are centrally symmetrically arranged and are both negative terminals for data transmission. TX1+, TX1- and TX2+, TX2- are two pairs of differential signal pairs used for data transmission, and high-speed signal transmission is achieved by changing the positive and negative polarity voltage.
[0071] RX1+ and RX2+ are arranged symmetrically at the center and are both positive terminals for data reception. RX1- and RX2- are arranged symmetrically at the center and are both negative terminals for data reception. RX1+, RX1- and RX2+, RX2- are two pairs of differential signal pairs used for receiving data. The received signal is analyzed by the change of positive and negative polarity voltage.
[0072] DD1+ and DD2+ are arranged symmetrically at the center and are both positive terminals of the differential data line test points. DD1- and DD2- are arranged symmetrically at the center and are both negative terminals of the differential data line test points. DD+ and DD- are the positive and negative terminals of the differential data signal, used for high-speed anti-interference transmission.
[0073] The other eighteen holding holes are functional probe holding holes 22. Among them, six spring probes 1 for grounding are distributed in the six ground probe holding holes on both sides of the first connector body 2 to form six ground terminals (i.e., GND). Six spring probes 1 for providing power are set in the six power probe holding holes in the fourth and sixth columns to form six power terminals (i.e., Vbus). Through the design of six pairs of Vbus+GND, the current is shared and the isolation effect is also increased.
[0074] Two spring probes 1, used for other auxiliary functions or as backup signal lines, are symmetrically arranged in two auxiliary probe holding holes on both sides of the first connector body 2, forming two auxiliary terminals (i.e., SBU1 and SBU2), which can be connected to different devices or functional modules as needed.
[0075] Two spring probes 1 for connection detection are symmetrically arranged in two configuration channel probe holding holes on both sides of the first connector body 2, forming two configuration channel terminals (i.e., CC1 and CC2), which can be used to detect the correct insertion, detect the USB connection status, identify the power and current supply capabilities, and manage the establishment of data and Vbus connections between USB devices.
[0076] Two spring probes 1 (i.e., TBDs) are reserved on the first connector body 2 for definition, which can be flexibly defined as needed.
[0077] It should be noted that, in the above embodiments, the first groove 211 can also be formed inside the functional probe holding hole 22, so that the pin arrangement and functional allocation of the male connector are not restricted, which is not limited here.
[0078] Please see Figures 1 to 10 The second aspect of this application provides a female connector for mating with the male connector described in the above embodiments, including contact terminals 3 and a second connector body 4. There are multiple contact terminals 3, which are made of metal, and each contact terminal 3 corresponds to a multiple spring probes 1, enabling multi-point electrical conduction.
[0079] The second connector body 4 is provided with multiple limiting holes 41, and multiple contact terminals 3 are respectively arranged in the multiple limiting holes 41 to achieve limiting and fixing of multiple contact terminals 3. The second connector body 4 is usually made of insulating material (such as plastic), which can effectively isolate electrical interference between contact terminals 3 and avoid short circuit risk.
[0080] In some embodiments of this application, please refer to Figures 7 to 10 The outer wall of the contact terminal 3 is provided with a second groove 31, which is set towards the inner wall of the limiting hole 41. This can form an air gap between the contact terminal 3 and the inner wall of the limiting hole 41, thereby increasing impedance, reducing energy loss, and reducing crosstalk when the signal is transmitted through the contact terminal 3.
[0081] In some embodiments of this application, please refer to Figure 9 and Figure 10 The second groove 31 is an annular groove provided on the outer periphery of the contact terminal 3, which can form a uniform annular air gap on the outer periphery of the contact terminal 3, thereby increasing the impedance and reducing the coupling capacitance and mutual inductance between adjacent contact terminals 3, thus reducing high-frequency signal crosstalk.
[0082] Please see Figures 1 to 10The third aspect of this application provides a connector assembly, including the male connector and the female connector described in the above embodiments, which can meet the requirements for high-speed signal transmission.
[0083] In some embodiments of this application, the connector assembly further includes a connection structure for connecting the male connector and the female connector. Specifically, the connection structure allows the first connector body 2 and the second connector body 4 to fit tightly together, so that the metal probe 11 of the spring probe 1 abuts tightly against the abutment end 32 of the contact terminal 3 under the elastic force of the elastic member 13. Figure 6 and Figure 7 As shown, a stable and reliable connection can be achieved between the male connector and the female connector.
[0084] It should be noted that the connection structure can be a snap-fit structure, a magnetic structure, etc. As long as the metal probe 11 can be tightly pressed against the contact end 32 of the contact terminal 3 under the elastic force of the elastic element 13, the purpose of this application can be achieved.
[0085] As a specific embodiment of this application, please refer to Figure 1 , Figure 3 and Figure 8 The connection structure includes buckles 23 disposed on both sides of the first connector body 2 and slots 42 disposed on both sides of the second connector body 4. Through the connection of buckles 23 and slots 42, the first connector body 2 and the second connector body 4 can be tightly fitted together.
[0086] In some embodiments of this application, please refer to Figure 6 The metal sleeve 14 of the spring probe 1 extends out of the first connector body 2 from the end opposite to the contact terminal 3, and the end of the contact terminal 3 opposite to the spring probe 1 (i.e. the connection end 33) extends out of the second connector body 4. They can be used to connect with other terminals or circuit boards respectively, so as to realize signal transmission between different devices through the connector assembly.
[0087] In some embodiments of this application, the above-described connector assembly is simulated and tested to meet the requirements of the USB4 Gen3×2 connector.
