[0042] For the purposes of promoting an understanding of the principles of the application, reference will now be made to the embodiments illustrated in the drawings. It is expressly understood that the drawings are for illustration only and that the application can be embodied in many different forms. In the drawings:

[0043] It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. It is also possible in the present application that units operate as a common unit or units, and / or that one or more processing units may be used in connection with performing the operations of the example embodiments of the present application. Therefore, use of the terms "processor" or "controller" herein can also include the assumption that any one of a common processing unit or units and / or one or more processing units are used in a cooperative relationship with one another.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. All publications, patent applications, patents, and other references mentioned herein are incorporated by reference in their entirety for the purpose of disclosing and describing the compositions and / or methodologies that are described in the publications, which might be used in connection with the application. In addition, the materials, methods, and examples are illustrative only and not intended to be limiting.

[0045] This application provides a connector including a plug connector and a socket connector; the plug connector includes a first base and a plug terminal, the first base forming a first mounting groove and a first pair of cavities communicating with each other, the plug terminal passing through the first mounting groove and connected to the first base, the plug terminal having an abutment portion corresponding to the first pair of cavities; the socket connector includes a second base and a socket terminal, the second base forming a second mounting groove and a second pair of cavities communicating with each other, the inner wall of the second pair of cavities having a protruding tongue portion, the tongue portion forming a first fixing groove communicating with the second mounting groove, the socket terminal passing through the second mounting groove and connected to the second base, the socket terminal portion being located in the first fixing groove and connected to the tongue portion, the first base being located in the second pair of cavities and inserted into the second base, and the tongue portion being located in the first pair of cavities and inserted into the first base, the abutment portion abutting against the socket terminal in the second pair of cavities.

[0046] The aforementioned connector, because the first base has a connecting first mounting groove and a first pair of mating cavities, the plug terminal passes through the first mounting groove and connects to the first base, allowing the plug terminal to be installed on the first base. Furthermore, because the contact portion of the plug terminal is correspondingly positioned with the first pair of mating cavities, the first base is located within the second pair of mating cavities and is inserted into the second base. The tongue portion is located within the first pair of mating cavities and is inserted into the first base, allowing the plug connector and the socket connector to be inserted into each other. This interlocking connection between the plug connector and the socket connector provides good stability during floating. Because the socket terminal portion is located within the first fixing groove and connects to the tongue portion, and the contact portion abuts against the socket terminal within the second pair of mating cavities, combined with the interlocking connection between the plug connector and the socket connector, a reliable electrical connection between the plug connector and the socket connector is achieved, solving the problem of poor electrical connection stability in connectors.

[0047] To better understand the technical solution and beneficial effects of this application, the following detailed description is provided in conjunction with specific embodiments:

[0048] like Figures 1 to 2b As shown, one embodiment of the connector 10 includes a plug connector 100 and a socket connector 200, which are mated together. In one embodiment, the plug connector 100 includes a first base 100a and a plug terminal 100b. The first base 100a has a first mounting groove 102 and a first mating cavity 106 that communicate with each other. The plug terminal 100b passes through the first mounting groove 102 and is connected to the first base 100a, so that the plug terminal 100b is mounted on the first base 100a. The plug terminal 100b has an abutment portion 110, which is correspondingly disposed with the first mating cavity 106.

[0049] As shown in Figure 1 and Figure 2a In one embodiment, the socket connector 200 includes a second housing 200a and a socket terminal 200b. The second housing 200a is formed with a second mounting slot 202 and a second mating cavity 204 in communication. The inner wall of the second mating cavity 204 is provided with a tongue portion 204a. Referring to Figure 7 , the tongue portion 204a is formed with a first fixing slot 206 in communication with the second mounting slot 202. The socket terminal 200b is arranged in the second mounting slot 202 and connected with the second housing 200a. The socket terminal 200b is partially arranged in the first fixing slot 206 and connected with the tongue portion 204a, so that the socket terminal 200b is assembled with the second housing 200a and the tongue portion 204a, respectively. The first housing 100a is arranged in the second mating cavity 204 and connected with the second housing 200a, and the tongue portion 204a is arranged in the first mating cavity 106 and connected with the first housing 100a, so that the first housing 100a and the second housing 200a are inserted into each other. Thus, the plug connector 100 and the socket connector 200 are connected in a mating manner, and the mating interface of the plug connector 100 and the socket connector 200 has good stability during floating.

[0050] As shown in Figure 2a Further, the abutting portion 110 abuts against the socket terminal 200b in the second mating cavity 204, so that the plug terminal 100b and the socket terminal 200b abut and conduct electricity. Since the plug connector 100 and the socket connector 200 are connected in a mating manner, the mating interface of the plug connector 100 and the socket connector 200 has good stability during floating, and the plug terminal 100b and the socket terminal 200b are reliably electrically connected. Thus, the connector 10 has good electrical connection performance, and reliable signal transmission is achieved. Especially in high-temperature environments, high-vibration environments, or large-mechanical-impact environments, the connector 10 has stable floating connection performance.

[0051] The connector 10 described above, wherein the first base 100a has a first mounting groove 102 and a first pair of cavities 106 connected, the plug terminal 100b passes through the first mounting groove 102 and connects to the first base 100a, so that the plug terminal 100b is mounted on the first base 100a; and since the contact portion 110 of the plug terminal 100b is correspondingly provided with the first pair of cavities 106, the first base 100a is located in the second pair of cavities 204 and is inserted into the second base 200a, and the tongue portion 204a is located in the first pair of cavities 106 and is inserted into the first base 100a, so that the plug connector 100 and the socket connector are connected. The plug connector 100 and the socket connector 200 are inserted into each other, thus enabling the plug connector 100 and the socket connector 200 to be connected. This provides good stability of the plug-to-socket interface during floating. Since the socket terminal 200b is located in the first fixing groove 206 and connected to the tongue portion 204a, and the contact portion 110 abuts against the socket terminal 200b in the second mating cavity 204, coupled with the plug connector 100 and the socket connector 200 being connected, the plug connector 100 and the socket connector 200 are reliably electrically connected, solving the problem of poor electrical connection stability of the connector 10.

[0052] like Figure 2a As shown, in one embodiment, the connector 10 is a floating board-to-board connector 10, used to electrically connect two circuit boards 20. One plug connector 100 is installed on one circuit board, and the other plug connector 100 is installed on the other circuit board, realizing a floating electrical connection between boards.

[0053] like Figure 2a , Figure 3 and Figure 4As shown, in one embodiment, the first base 100a and the second base 200a are both frame fitting structures, i.e. the structure of the first base 100a fitting into the second base 200a and the structure of the second base 200a fitting into the first base 100a are both frame fitting structures. Specifically, the structure of the first base 100a fitting into the second base 200a is a first frame fitting structure, and the structure of the second base 200a fitting into the first base 100a is a second frame fitting structure. The first base 100a and the second base 200a are nested into each other, and the connection of the first base 100a and the second base 200a is more stable, which ensures the stability of the base during floating of the connector 10 and the ability to withstand high temperature, high vibration, and large mechanical impact. In this embodiment, the first base 100a is inserted into the second mating cavity 204 and fits into the second base 200a to form the first frame fitting structure. The tongue portion 204a is inserted into the first mating cavity 106 and fits into the first base 100a to form the second frame fitting structure. The first base 100a and the second base 200a are inserted into each other to form a stable frame nested structure. In one embodiment, the cross sections of the first frame fitting structure and the second frame fitting structure are both rectangular, which makes the first frame fitting structure and the second frame fitting structure better nested and floating, and the connection of the plug connector 100 and the socket connector 200 has a stable frame structure, which ensures the stability of the base during floating of the connector 10 and the ability to withstand high temperature, high vibration, and large mechanical impact. It should be understood that in other embodiments, the cross sections of the first frame fitting structure and the second frame fitting structure are not limited to be rectangular, but can also be square or other shapes.

[0054] As shown in Figure 2a , Figure 5 , Figure 6 and Figure 7 , in one embodiment, the number of plug terminals 100b is at least two, and the number of first mounting grooves 102 is at least two. Each first mounting groove 102 is in communication with the first mating cavity 106, and two plug terminals 100b are arranged in the two first mounting grooves 102, respectively, and are oppositely arranged on both sides of the tongue portion 204a. Meanwhile, referring to Figure 7In one of the embodiments, the number of the socket terminals 200b is at least two, the number of the second mounting slots 202 and the first fixing slots 206 is at least two, each of the second mounting slots 202 is in communication with the second pair of insertion cavities 204 and the corresponding first fixing slot 206, respectively, the two first fixing slots 206 are formed on the two sides of the tongue portion 204a, respectively, each of the socket terminals 200b is arranged in the corresponding second mounting slot 202 and connected with the second base 200a, each of the socket terminals 200b is partially arranged in the corresponding first fixing slot 206 and connected with the tongue portion 204a, so that each of the socket terminals 200b is assembled with the second base 200a and the tongue portion 204a. The abutting portions 110 of the two plug terminals 100b are in abutment with the two socket terminals 200b, respectively, so that the two plug terminals 100b are electrically connected with the two socket terminals 200b, respectively, so that the two plug terminals 100b are electrically connected with the two socket terminals 200b in one-to-one correspondence. Since the two plug terminals 100b are oppositely arranged on the two sides of the tongue portion 204a, and the two socket terminals 200b are arranged in the two first fixing slots 206 on the two sides of the tongue portion 204a and connected with the tongue portion 204a, respectively, the abutting portions 110 of the two plug terminals 100b are in abutment with the two socket terminals 200b, respectively, so that the abutting force generated by the abutting portions 110 of the two plug terminals 100b in abutment with the two socket terminals 200b, respectively, can be mutually cancelled out, and at the same time, the insertion of the tongue portion 204a and the first base 100a has better reliability, and thus the plug connector 100 and the socket connector 200 have better plugging force after being inserted and plugged, and thus the insertion of the plug connector 100 and the socket connector 200 has better reliability.

[0055] As Figures 7 to 9As shown in the figures, in one embodiment, the number of plug terminals 100b and the number of socket terminals 200b are both plural, and the plurality of plug terminals 100b are in one-to-one correspondence with the plurality of socket terminals 200b, so that each plug terminal 100b is in contact with a corresponding socket terminal 200b, and then each plug terminal 100b is electrically connected with the corresponding socket terminal 200b, so that the connector 10 can simultaneously realize the transmission of multiple signal channels. In this embodiment, the number of first mounting grooves 102, the number of first fixing grooves 206, and the number of second mounting grooves 202 are all plural, and the plurality of plug terminals 100b are arranged in two rows, and the two rows of plug terminals 100b are respectively located on the two sides of the tongue portion 204a. Correspondingly, the plurality of socket terminals 200b are arranged in two rows, and the two rows of socket terminals 200b are respectively located on the two sides of the tongue portion 204a. Each plug terminal 100b is arranged in the corresponding first mounting groove 102 and connected with the first base 100a, so that the plurality of plug terminals 100b are mounted on the first base 100a. Each socket terminal 200b is arranged in the corresponding second mounting groove 202 and connected with the second base 200a, and each socket terminal 200b is partially arranged in the corresponding first fixing groove 206 and connected with the tongue portion 204a.

[0056] As shown in the figures, Figure 2a , Figure 9 In one embodiment, the contact portions 110 of the plug terminals 100b are all bent towards the side close to the tongue portion 204a, so that the contact portions 110 better abut the socket terminals 200b. In this embodiment, the number of plug terminals 100b is at least two, and the contact portions 110 of the two plug terminals 100b are all bent towards the side close to the tongue portion 204a, so that the contact portions 110 of the two plug terminals 100b better abut the two socket terminals 200b respectively. In this embodiment, the contact portions 110 of the two plug terminals 100b are all bent towards the side close to the tongue portion 204a, and each plug terminal 100b is bent at the contact area from the frontmost portion of the terminal, so that the plug connector 100 and the socket connector 200 can each form a contact point on the left and right of the contact area, so that the plug connector 100 and the socket connector 200 have better plugging force after being plugged, and at the same time, the resistance of the plug connector 100 and the socket connector 200 when being plugged is smaller.

[0057] As shown in the figures, Figure 2a , Figure 6 , and Figure 9As shown, in one embodiment, the first base 100a is further formed with a through groove 104, which is respectively communicated with the first mounting groove 102 and the first mating cavity 106, so that the inner cavity of the first base is communicated with the peripheral space of the first base through the groove position of the through groove, avoiding the problem that the elastic deformation of the plug terminal is blocked when the plug connector and the socket connector are mated, and the through groove can effectively reduce the capacitance of the contact area of the plug terminal and the socket terminal, greatly improve the characteristic impedance of the contact area, and ensure that the characteristic impedance of the contact area meets the design requirements. In this embodiment, the second mounting groove 202 is communicated with the second mating cavity 204, and the second base 200a is a floating base 220, so that the socket terminal is inserted into the first fixed groove through the second mounting groove, and then the plug terminal reliably abuts and conducts with the socket terminal in the second mating cavity; in the use process, since the inner cavity of the first base is communicated with the peripheral space of the first base through the groove position of the through groove, the problem that the elastic deformation of the plug terminal is blocked when the plug connector and the socket connector are mated is avoided, and the through groove can effectively reduce the capacitance of the contact area of the plug terminal and the socket terminal, greatly improve the characteristic impedance of the contact area, and ensure that the characteristic impedance of the contact area meets the design requirements.

[0058] As shown in Figure 2a , Figure 6 and Figure 9 , further, the contact portion is correspondingly arranged with the through groove, that is, the contact portion 110 is located in the region where the first mounting groove 102 and the through groove 104 are correspondingly communicated, that is, the contact portion 110 is correspondingly arranged at the position where the first mounting groove 102 and the through groove 104 are communicated, so that the inner cavity of the first base is communicated with the peripheral space of the first base through the groove position of the through groove, avoiding the problem that the elastic deformation of the plug terminal is blocked when the plug connector and the socket connector are mated, and the through groove can effectively reduce the capacitance of the contact area of the plug terminal and the socket terminal, greatly improve the characteristic impedance of the contact area, and ensure that the characteristic impedance of the contact area meets the design requirements. Meanwhile, referring to Figure 9aIn addition, the first base 100a is formed with a through groove 104 in the region corresponding to the abutting portion 110, so that the abutting portion 110 can reliably elastically deform when abutting against the socket terminal 200b, i.e. the plug terminal 100b has a reliable deformation space at the position corresponding to the through groove 104 when abutting against the socket terminal 200b, thus avoiding the problem that the elastic deformation of the plug terminal 100b is hindered by the first base 100a, i.e. the plug terminal 100b is compressed without hindrance when pressed, the through groove 302 penetrates the inner cavity of the plug connector 100 and the peripheral space, exposes the abutting portion 110 of the plug terminal 100b to the air, the terminal can be observed from the outside of the connector 10, which serves as a compression avoidance space for the elastic wall, and greatly improves the characteristic impedance of the electrical connection of the connector 10 after the plug connector 100 and the socket connector 200 are plugged together. In one embodiment, the abutting portion 110 is partially protruding in the first plugging cavity 106, so that the abutting portion 110 can reliably abut against the socket terminal 200b when the plug connector 100 and the socket connector 200 are plugged together.

[0059] As shown in Figure 7 In one embodiment, the second base 200a includes a fixed base 210 and a floating base 220, the fixed base 210 is formed with a receiving groove 203, and the floating base 220 is located in the receiving groove 203 and movably connected with the fixed base 210.
