[0001] This application relates to the field of connector technology, and in particular to a connector. Background Technology
[0002] Currently, connectors used to electrically connect coaxial cables to printed circuit boards (PCBs) generally include a coaxial cable connection assembly and a board-end connection assembly. When electrically connecting a coaxial cable to a first conductive part on a PCB, the coaxial cable connection assembly connected to the coaxial cable needs to be mated with a board-end connection assembly mounted on the PCB. After mating, the first conductive terminal in the coaxial cable connection assembly contacts the second conductive terminal in the board-end connection assembly. The coaxial cable is only fixed by the end connected to the coaxial cable connection assembly, while the other part of the coaxial cable is suspended above the PCB. During use, the shaking of the coaxial cable or the movement of the coaxial cable connection assembly can easily affect the connection between the coaxial cable connection assembly and the board-end connection assembly, which may lead to contact failure between the first and second conductive terminals, thus hindering the improvement of the connector's contact stability.

[0036] 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 herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
[0037] like Figures 1 to 17 As shown, it is a connector 100 according to one embodiment of this application.
[0038] like Figures 1 to 4 As shown, the connector 100 includes: a first connecting component 11, a second connecting component 12, and a housing 13.
[0039] The connector 100 is used to electrically connect the printed circuit board 20 and the coaxial cable 30.
[0040] Specifically, please refer to Figure 4 As shown, a first conductive part 21 is provided on the printed circuit board 20.
[0041] Specifically, please refer to Figure 3 As shown, the two ends of the coaxial cable 30 along its length are its ends 31, and the coaxial cable 30 is connected to the second connecting assembly 12 through its ends 31. The section between the two ends 31 of the coaxial cable 30 is its cable body 30a, and the section of cable adjacent to the ends 31 is the joint 32. The joint 32 extends from the ends 31, and the free end 311 of the ends 31 is connected to the second connecting assembly 12.
[0042] The first connecting component 11 is disposed on the printed circuit board 20 and is a board-end connecting component; the second connecting component 12 is connected to the coaxial cable 30 and is a coaxial cable connecting component; through the docking of the first connecting component 11 and the second connecting component 12, the electrical connection between the first conductive part 21 of the printed circuit board 200 and the coaxial cable 300 is realized.
[0043] Please see Figures 11 to 15As shown, a first connecting component 11 is disposed on a printed circuit board 20. The first connecting component 11 includes a first contact terminal 111, which is connected to a first conductive portion 21 of the printed circuit board 20. A second connecting component 12 is mated with the first connecting component 11. The second connecting component 12 includes a second contact terminal 121, which includes a contact portion 1211 and a wiring portion 1212. The contact portion 1211 contacts the first contact terminal 111, and the wiring portion 1212 contacts the free end 311 of one end 31 of the coaxial cable 30. In other words, the first conductive portion 21, the first contact terminal 111, the second contact terminal 121, and the free end 311 of the coaxial cable 30 are connected sequentially, realizing the electrical connection between the first conductive portion 21 of the printed circuit board 20 and the coaxial cable 30.
[0044] Please refer to Figure 1 , Figure 6 as well as Figure 11 and Figure 12 As shown, the housing 13 is used to accommodate the second connecting component 12 and the end 31 of the coaxial cable 30. The housing 13 includes a housing body 131 and a support portion 132 connected to the housing body 131. The second connecting component 12 and the end 31 of the coaxial cable 30 are accommodated in the housing body 131. The support portion 132 is correspondingly provided with the joint portion 32 of the coaxial cable 30. The support portion 132 includes two fixing portions 1321 that are respectively fixed to the printed circuit board and a bending portion 1322 that connects the two fixing portions 1321. The two fixing portions 1321 are respectively located on both sides of the joint portion 32, and the bending portion 1322 surrounds the joint portion 32.
[0045] The support portion 132 secures the joint portion 32 of the coaxial cable 30, and the main body portion 131 of the housing 13 secures the second connecting assembly 12 and the end portion 31 of the coaxial cable 30. The housing 13 is fixed to the printed circuit board 20 by the support portion 132, thereby improving the connection strength between the housing and the printed circuit board.
[0046] In this embodiment, the second connecting component and the end of the coaxial cable are simultaneously housed within the housing. The support portion of the housing is fixedly connected to the printed circuit board via its fixing portion, which improves the connection strength between the housing and the printed circuit board. During use, the housing is less prone to movement. Due to the constraint of the housing on the end and joint of the second connecting component and the coaxial cable, the displacement of the second connecting component and the coaxial cable is relatively reduced. This reduces the impact of the movement of the second connecting component and the coaxial cable on the docking between the first connecting component and the second connecting component, which helps to maintain the relative stability of the first connecting component and the second connecting component. Consequently, the contact between the first contact terminal and the second contact terminal becomes stable, which helps to improve the contact stability of the connector.
[0047] As one implementation method, please refer to Figure 1 , Figure 6 as well as Figure 11 and Figure 12 As shown, the bending portion 1322 includes a connecting plate 13221 and two bending plates 13222. The connecting plate 13221 is disposed opposite to the side of the printed circuit board 20 that has the first conductive portion 21. The two bending plates 13222 are formed by bending from the edge of the connecting plate 13221 toward the printed circuit board 20. The side of the two bending plates 13222 that is close to the printed circuit board 20 is connected to the two fixing portions 1321 respectively.
[0048] In this embodiment, one bending plate 13222, the connecting plate 13221 and the other connecting plate 13221 are sequentially connected to form a bending portion 1322 surrounding the joint portion 32. The bending portion 1322 has a certain constraint effect on the joint portion 32. During use, the joint portion 32 can be constrained within the constraint space formed by the bending portion 1322 and the printed circuit board 20, thereby reducing the displacement of the joint portion 32.
[0049] In some implementations, please refer to [the relevant documentation]. Figure 1 As shown, the bent plate 13222 is provided with a reinforcing rib 13223, which is formed by recessing from the side of the bent plate 13222 away from the joint 32 to the side of the bent plate 13222 facing the joint 32.
[0050] In this embodiment, the addition of the reinforcing rib 13223 helps to increase the support strength of the bent plate 13222.
[0051] In some implementations, please refer to [the relevant documentation]. Figure 1 as well as Figure 6 As shown, the fixing part 1321 has a fixing hole 1323, and the fixing part 1321 is fixed to the printed circuit board 20 by a locking member 22 that passes through the fixing hole 1323 and the printed circuit board 20 in sequence. For example, the locking member 22 can be a locking screw.
[0052] As one implementation method, please refer to Figures 11 to 15As shown, the first contact terminal 111 includes a contact plate 1111, a contact ring 1112, and a contact post 1113. The contact plate 1111 and the contact ring 1112 are disposed on the side of the printed circuit board 20 where the first conductive part 21 is provided. The contact plate 1111 is in contact with the first conductive part 21. The contact ring 1112 is connected to the contact plate 1111 and placed on the printed circuit board 20. The contact post 1113 is connected to the contact ring 1112. The contact post 1113 includes a contact sidewall 1113a extending from the inner periphery of the contact ring 1112 in a direction away from the contact ring 1112 and a contact top wall 1113b disposed on the side of the contact sidewall 1113a away from the contact ring 1112. The contact post 1113 is connected to the contact part 1211.
[0053] For example, the second connecting component 12 can be inserted into the first connecting component 11 along the first insertion direction S1. The first insertion direction S1 can be perpendicular to the side of the printed circuit board 20 where the first conductive part 21 is provided. The contact sidewall 1113a of the contact post 1113 can extend along the first insertion direction S1.
[0054] In this embodiment, by setting the contact post 1113, the contact post 1113 comes into contact with the contact portion 1211 of the second contact terminal 121, which helps to increase the contact area between the two.
[0055] In some implementations, please continue to refer to Figure 7 And reading Figures 11 to 15 As shown, the first connecting assembly 11 further includes a first insulator 112 and a connecting shell 113 sleeved on the first insulator 112. The first insulator 112 includes a first insulating body 1121, which has a first receiving cavity 1121a. The first insulating body 1121 has a first opening 1121b communicating with the first receiving cavity 1121a. The side of the first insulating body 1121 facing the printed circuit board 20 is connected to the printed circuit board 20. At least a portion of the contact plate 1111 and the contact ring 1112 are housed in the first receiving cavity 1121a. The contact post 1113 extends out of the first insulator 112 through the first opening 1121b.
[0056] The connecting shell 113 includes an annular connecting seat 1131 and a connecting base 1132. The annular connecting seat 1131 surrounds the contact post 1113 and is spaced apart from the contact post 1113. The connecting base 1132 is formed by bending from the edge of the annular connecting seat 1131 on the side close to the printed circuit board 20 in a direction away from the annular connecting seat 1131. The connecting base 1132 is sleeved on the first insulating body 1121 and connected to the printed circuit board 20.
[0057] In this embodiment, the first insulator 112 is provided to more firmly connect the contact plate 1111 and the contact ring 1112 to the printed circuit board 20; the first insulator 112 is more firmly connected to the printed circuit board 20 by the connection base 1132; thus improving the connection strength between the first connection component 11 and the printed circuit board 20.
[0058] In some implementations, please refer to [the relevant documentation]. Figure 11 as well as Figure 14 As shown, the first insulator 112 further includes an abutting flange 1121c formed on the side of the first insulating body 1121 facing away from the printed circuit board 20, at least one first connector 1121d formed on the outer edge of the first insulating body 1121 and connected to the printed circuit board, and a second opening 1121e communicating with the first receiving cavity 1121a. The annular connecting seat 1131 has a first notch 1131a formed on the edge near the printed circuit board 20 to avoid the abutting flange 1121c. The abutting flange 1121c abuts against the inner wall of the first notch 1131a. The connecting base 1132 has a second notch 1132a formed to avoid the first connector 1121d. One side of the contact plate 1111 extends out of the first insulator 112 through the second opening 1121e.
[0059] In this embodiment, the engagement of the abutting flange 1121c and the first notch 1131a, as well as the engagement of the first connector 1121d and the second notch 1132a, helps to improve the connection strength between the first insulator 112 and the connecting shell 113.
[0060] In some implementations, please refer to Figure 11 and Figure 12 As shown, the coaxial cable 30 is connected to the second connecting component 12 along the second insertion direction S2. The second insertion direction S2 is parallel to the extension direction of the coaxial cable 30 and perpendicular to the first insertion direction S1. The second contact terminal 121 also includes a contact connection portion 1213 connecting the contact portion 1211 and the wiring portion 1212. The contact connection portion 1213 can be arranged along the second insertion direction S2. The contact portion 1211 and the wiring portion 1212 are respectively located at both ends of the contact connection portion 1213 along the second insertion direction S2. The contact portion 1211 includes two contact springs 1211a arranged opposite to each other in a third direction S3. The third direction S3 is perpendicular to the first insertion direction S1 and perpendicular to the second insertion direction S2. The contact springs 1211a extend from one side edge of the contact connection portion 1213 toward the contact ring 1112. The two contact springs 1211a are arranged opposite to each other to lock the contact post 1113 between the two contact springs 1211a. The contact springs 1211a abut against the contact sidewall 1113a of the contact post 1113.
[0061] The wiring portion 1212 includes two contact hangers 1212a disposed opposite to each other in the third direction S3. The contact hangers 1212a extend from the other edge of the contact connection portion 1213 toward the side of the printed circuit board 20 where the first conductive portion 21 is provided. The two contact hangers 1212a are disposed opposite to each other to engage the free end 311 of the end 31 between the two contact hangers 1212a. The contact hangers 1212a are in contact with the free end 311 of the end 31.
[0062] In this embodiment, when the second contact terminal 121 is displaced along the second insertion direction S2, even if the contact portion 1211 and the contact post 1113 move relative to each other along the second insertion direction S2, they can still make contact with each other within a certain range of movement; even if the wiring portion 1212 and the free end 311 of the end 31 move relative to each other along the second insertion direction S2, they can still make contact with each other within a certain range of movement; this is beneficial to improving the contact stability of the first contact terminal 111 and the second contact terminal 121 as well as the contact stability of the second contact terminal 121 and the coaxial cable 30.
[0063] As one implementation method, please refer to Figure 11 and Figure 12 as well as Figure 16 and Figure 17 As shown, the second connecting assembly 12 further includes a second insulator 122, which includes an insertion insulating portion 1221 that is inserted into the first connecting assembly 11. The insertion insulating portion 1221 has a third receiving cavity 12211 for receiving the contact portion 1211 and a third opening 12212 communicating with the third receiving cavity 12211.
[0064] When the insertion insulating part 1221 is inserted into the first connecting assembly 11, the insertion insulating part 1221 is inserted into the annular connecting seat 1131, and the contact post 1113 of the first contact terminal 111 extends into the third receiving cavity 12211 through the third opening 12212 and contacts the contact part 1211. For details, please refer to... Figure 7 As shown, the contact post 1113 extends into the third receiving cavity 12211 through the third opening 12212 and is inserted between the two contact springs 1211a. The contact springs 1211a are pressed along the third direction S3 in a direction away from the contact post 1113, and the contact springs 1211a abut against the contact post 1113.
[0065] In some implementations, please refer to Figure 11 and Figure 12 as well as Figure 16 and Figure 17As shown, the second insulator 122 also includes a wiring insulation portion 1222 connected to the plug-in insulation portion 1221. The wiring insulation portion 1222 has a fourth receiving cavity 1222a for accommodating the wiring portion 1212 and a fourth opening 1222b communicating with the fourth receiving cavity 1222a. The fourth receiving cavity 1222a communicates with the third receiving cavity 12211.
[0066] When the end 31 of the coaxial cable 30 is connected to the wiring insulation part 1222, the free end 311 of the end 31 extends into the fourth receiving cavity 1222a through the fourth opening 1222b and contacts the wiring part 1212. Specifically, the free end 311 of the end 31 is inserted between the two contact suspension pieces 1212a along the second insertion direction S2 and contacts the two contact suspension pieces 1212a respectively.
[0067] In some embodiments, the housing body 131 of the housing 13 includes a first outer shell 1311 sleeved on the insertion insulating portion 1221 and at least a portion of the first connecting assembly 11, a second outer shell 1312 sleeved on the wiring insulating portion 1222, and a third outer shell 1313 connected between the second outer shell 1312 and the support portion 132. The first outer shell 1311, the second outer shell 1312, the third outer shell 1313, and the support portion 132 are sequentially connected along the second insertion direction S2.
[0068] For details, please continue reading Figure 7 , Figure 9 as well as Figure 11 and Figure 12 As shown, the first outer shell 1311 includes a first top 1311a and a first side portion 1311b formed by bending from the outer edge of the first top 1311a in a direction close to the printed circuit board 30. The first side portion 1311b is sleeved on the annular connector 1131, and a first snap-fit structure 1311c is formed on the inner wall of the first side portion 1311b. A second snap-fit structure 1131b that mates with the first snap-fit structure 1311c is provided on the outer wall of the annular connector 1131. When the first outer shell 1311 is sleeved on the insertion insulating part 1221 and the annular connector 1131, the first snap-fit structure 1311c and the second snap-fit structure 1131b snap together to fix the first outer shell 1311 and the annular connector 1131.
[0069] The second housing 1312 includes a second top 13121 and a clamping portion 13122 disposed on the outer edge of the second top 13121. The second top 13121 and the clamping portion 13122 together enclose a space for accommodating the wiring insulation portion 1222, so as to constrain and fix the wiring insulation portion 1222.
[0070] In some implementations, please refer to Figure 4 and Figure 7 as well as Figures 13 to 15 As shown, the printed circuit board 20 has a second conductive part 23 on the side where the first conductive part 21 is provided. The second conductive part 23 is spaced apart from the first conductive part 21. The portion of the connecting base 1132 connected to the printed circuit board 20 contacts the second conductive part 23. That is, in the first insertion direction S1, the second conductive part 23 is located between the printed circuit board 20 and the connecting base 1132. Due to the provision of the first insulator 112, any contact between the first contact terminal 111 and the connecting shell 113 can be avoided, thereby preventing the first conductive part 21 and the second conductive part 23 from forming a short circuit due to electrical connection.
[0071] Please see Figure 6 , Figure 8 and Figure 18 As shown, the coaxial cable 30 includes a conductor 301, an insulating layer 302, a braided layer 303, and an insulating outer layer 304 arranged radially from the inside to the outside. The conductor 301 and the braided layer 303 are both conductive layers, and the braided layer 303 is made of several small fine wires braided together.
[0072] The core 301 in the coaxial cable 30 is connected to the connector 1212 to achieve electrical connection with the first conductive part 21. That is, the free end 311 of the end 31 of the coaxial cable 30 is part of the core 301. The other three parts on the free end 311 are stripped. The core 301, which is the free end 311, can be constructed to fit the connector 1212 for better contact with the connector 1212.
[0073] The braided layer 303 is connected to the housing 13, that is, the braided layer 303 can be connected to the third outer shell 1313, so that the braided layer 303 and the second conductive part 23 are electrically connected through the contact between the first outer shell 1311 and the annular connecting seat 1131. Exemplarily, the housing 13 and the connecting shell 113 can be made of conductive materials, for example, the housing 13 and the connecting shell 113 can both be made of metal materials.
[0074] In some implementations, please refer to Figure 8As shown, the third outer shell 1313 includes a third top 1313a and a first clamping portion 1313b and a second clamping portion 1313c disposed on the outer edge of the third top 1313a. The first clamping portion 1313b and the second clamping portion 1313c are arranged sequentially along the second insertion direction S2. The third top 1313a contacts the braided layer 303, that is, the portion of the end 31 of the coaxial cable 30, excluding the free end 311, contacts the third top 1313a. The original insulating outer layer 304 on the portion of the end 31 located inside the third outer shell 1313 and in contact with the third top 1313a is peeled off to achieve contact between the braided layer 303 and the third outer shell 1313. The first clamping portion 1313b clamps the end 31 circumferentially along the coaxial cable 30, and the second clamping portion 1313c clamps the end 31 circumferentially along the coaxial cable 30.
[0075] In some implementations, please refer to Figure 6 As shown, the connecting plate 13221 of the support portion 132 can also contact the braided layer 303, that is, the joint portion 32 of the coaxial cable 30 contacts the connecting plate 13221. The original insulating outer layer 304 on the part of the joint portion 32 located in the bend portion 1322 and in contact with the connecting plate 13221 is peeled off, so as to achieve contact between the braided layer 303 and the connecting plate 13221.
[0076] For example, the first top 1311a, the second top 13121, the third top 1313a and the connecting plate 13221 can be parallel to the side of the printed circuit board 20 where the first conductive part 21 is provided, and the first top 1311a, the second top 13121, the third top 1313a and the connecting plate 13221 can be connected in sequence to form an integral structure.
