Description

Technical Field

[0001] This application relates to the field of connector technology, specifically to a multi-channel connector, connector assembly, and electronic device. Background Technology

[0002] Currently, more and more connectors need to include other electronic components and require complex processes for assembly, such as thermal riveting and potting, which increases the difficulty of connector assembly and manufacturing costs, and affects the efficiency of connector assembly.

[0003] Therefore, how to design a connector structure that is simple, has low production cost, and high connection strength is a problem that we urgently need to solve. Utility Model Content

[0004] This application provides a multi-channel connector, connector assembly, and electronic device that simplifies the connector assembly process, reduces the difficulty of connector assembly, improves connector assembly efficiency, has a simple overall connector structure, reduces manufacturing costs, and is conducive to industrial production.

[0005] This application provides a multi-port connector, comprising: a base, connecting terminals, a first protrusion, a housing, a tongue, and a second protrusion. The base has opposing first and second surfaces; the connecting terminals include at least two, and the connecting terminals are disposed on the first surface of the base; the first protrusion is disposed on the connecting terminals; the housing has opposing third and fourth surfaces; the tongue is disposed on the fourth surface of the housing, and the tongue is used to connect the connecting terminals to fix the base to the housing; the second protrusion is disposed on the tongue; wherein, when the base is connected to the housing, the connecting terminals pass through the housing from the third surface and extend out from the fourth surface, and the first protrusion passes over the second protrusion and engages with it.

[0006] The beneficial effects of this application are as follows: During the assembly process of the base and the housing, the connecting terminal moves along the second protrusion of the tongue after passing through the housing.

When the first protrusion completely passes the second protrusion, it resets, and the first protrusion and the second protrusion abut against each other to achieve a locking connection. The first and second protrusions in the locking state can provide locking force for the base and the housing. A tight connection between the first and second protrusions can be achieved without using complex processes such as hot riveting and potting, which simplifies the connector assembly process, reduces the assembly difficulty of the connector, improves the assembly efficiency of the connector, and simplifies the overall structure of the connector, reduces manufacturing costs, and is conducive to industrial production.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0021] In this application, unless otherwise expressly specified and limited, the terms "connected," "linked," "stacked," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two elements or the interaction between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] Firstly, referring to Figure 1 This application provides a multi-channel connector, including: a base 10, a connection terminal 20, a first protrusion 30, a housing 40, a tongue 50, and a second protrusion 60.

[0023] Specifically, the base 10 has a first surface and a second surface; the base 10 is usually made of plastic, metal or ceramic, etc. The most suitable material can be selected according to the actual application scenario so that the assembled connector can have excellent performance in the corresponding application scenario.

[0024] The connecting terminal 20 includes at least two terminals, which are disposed on the first surface of the base 10. One end of the connecting terminal 20 is disposed inside the base 10, and the connecting terminals 20 are arranged along one side of the first surface of the base 10 to the other side. The connecting terminals 20 are generally made of materials with excellent conductivity. In some cases, in order to reduce resistance, gold or tin may be plated on the connecting terminals 20.

[0025] The first protrusion 30 is disposed on the connecting terminal 20; when the base 10 and the housing 40 are assembled, the first protrusion 30 faces the tongue 50, wherein the first protrusion 30 and the connecting terminal 20 can be an integral structure, which can improve the strength and integrity between the first protrusion 30 and the connecting terminal 20.

[0026] The housing 40 has opposing third and fourth surfaces; during multi-channel connector assembly, the third surface of the housing 40 corresponds to and fits against the first surface of the base 10. The housing 40 is made of the same material as the base 10, but can also be made of plastic, metal, or ceramic. The most suitable material can be selected based on the specific application scenario to ensure that the assembled connector exhibits excellent performance in the corresponding application.

[0027] The tongue 50 is disposed on the fourth side of the housing 40. The tongue 50 is used to connect the connecting terminal 20 to fix the base 10 to the housing 40. The tongue 50 is usually made of high-strength insulating materials such as PA10T and PPS, which can both support the connecting terminal 20 and prevent short circuits.

[0028] The second protrusion 60 is disposed on the tongue 50; when the base 10 and the housing 40 are assembled, the second protrusion 60 faces the connecting terminal 20, wherein the second protrusion 60 and the tongue 50 can be an integral structure, which can improve the strength and integrity between the second protrusion 60 and the tongue 50.

[0029] When the base 10 is connected to the housing 40, the connecting terminal 20 passes through the housing 40 from the third side and extends out from the fourth side, and the first protrusion 30 passes over the second protrusion 60 and engages with it.

[0030] In the above manner, during the assembly process of the base 10 and the housing 40, the connecting terminal 20 passes through the housing 40 and moves along the second protrusion 60 of the tongue 50. When the first protrusion 30 contacts the second protrusion 60, the base 10 and the housing 40 continue to move, and the connecting terminal 20 deforms, allowing the first protrusion 30 to pass through the second protrusion 60. When the first protrusion 30 completely passes over the second protrusion 60, it resets, and the first protrusion 30 and the second protrusion 60 abut against each other to achieve a locking engagement. The first protrusion 30 and the second protrusion 60 in the locked engagement state can provide locking force for the base 10 and the housing 40. A tight connection between the first protrusion 30 and the second protrusion 60 can be achieved without using complex processes such as hot riveting and potting, which simplifies the connector assembly process, reduces the assembly difficulty of the connector, improves the assembly efficiency of the connector, and simplifies the overall structure of the connector, reduces manufacturing costs, and is conducive to industrial production.

[0031] In one embodiment of this application, reference is made to Figure 2 and Figure 5 The housing 40 is also provided with an assembly channel 401, which extends through the housing 40 along the third and fourth surfaces. The assembly channel 401 is used for the connection terminal 20 to pass through the housing 40 when the base 10 is connected to the housing 40. The assembly channel 401 is rectangular or square when viewed from the third surface of the housing 40.

[0032] It should be noted that in other embodiments, the assembly channel 401 may also be of other shapes, but it is necessary to ensure that the shape of the assembly channel 401 is the same as or approximately the same as the cross-sectional shape of the connecting terminal 20 and the first protrusion 30, so that the connecting terminal 20 and the first protrusion 30 can pass through the housing 40 as a whole, and also to avoid the problem of the connected terminal 20 becoming loose in the assembly channel 401 after assembly.

[0033] In the above manner, when the base 10 and the housing 40 are assembled, the connecting terminal 20 can pass through the housing 40 through the assembly channel 401, and under the guidance of the tongue 50, the first protrusion 30 passes over the second protrusion 60 and is locked in place. With the help of the assembly channel 401, the connecting terminal 20 is fixed in the assembly channel 401, thereby realizing the rapid assembly of the base 10 and the housing 40.

[0034] In one embodiment of this application, reference is made to Figure 5 The tongue 50 is positioned adjacent to the assembly channel 401. The tongue 50 is positioned near the fourth surface of the housing 40 within the assembly channel 401, or it can be positioned at the edge of the fourth surface of the housing 40 within the assembly channel 401. In this way, the layout of the tongue 50 on the housing 40 can be made more reasonable, which is conducive to making the arrangement of the connecting terminal 20 and the tongue 50 after snap-locking more compact, and is conducive to reducing the size of the base 10 and the housing 40 after assembly.

[0035] In one embodiment of this application, reference is made to Figure 2 The assembly channel 401 has a third transition surface 402 at one end edge of the third surface of the housing 40; wherein, in this embodiment, the third transition surface 402 is a slope or an arc surface; in this way, when the connecting terminal 20 is inserted into the assembly channel 401, the third transition surface 402, which has a slope or arc surface structure and is arranged around one end of the assembly channel 401, helps the connecting terminal 20 to slide into the assembly channel 401, reduces the difficulty of inserting the connecting terminal 20 into the assembly channel 401, and improves the assembly efficiency of the base 10 and the housing 40.

[0036] It should be noted that in other embodiments, the third transition surface 402 can also be configured as a combination structure composed of multiple inclined surfaces and arc surfaces. The third transition surface 402 under this combination structure can also facilitate the insertion of the connection terminal 20 into the assembly channel 401.

[0037] Reference Figure 3 and Figure 4A connector 201 is provided at the end of the connecting terminal 20 away from the first surface of the base 10. In this embodiment, a first sliding portion 2011 and a second sliding portion 2012 are respectively provided at the end of the connector 201 away from the third surface of the base 10. The first sliding portion 2011 is a sloped or arc-shaped surface, and the second sliding portion 2012 is a sloped or arc-shaped surface. The end of the connector 201 away from the third surface of the base 10 is the insertion end, that is, the end of the connector 201 that first enters the assembly channel 401. Specifically, referring to… Figure 5 The connector 201 and the connecting terminal 20 can be an integral structure. The cross-section of the connecting terminal 20 can be rectangular or square. In this case, there are two first sliding parts 2011 and two second sliding parts 2012. The two first sliding parts 2011 are arranged opposite each other, and the two second sliding parts 2012 are arranged opposite each other. The first sliding parts 2011 and the second sliding parts 2012 are spaced apart at the insertion end of the connector 201. In this way, the edge of the connector 201 used for insertion into the assembly channel 401 can be set as a bevel or arc surface, so that the edge of the insertion end of the connector 201 has a uniform transition structure, which helps the connector 201 slide into the assembly channel 401, reduces the difficulty of inserting the connector 201 into the assembly channel 401, and improves the assembly efficiency of the base 10 and the housing 40.

[0038] In practical applications, refer to Figure 4 The first sliding part 2011 has an arc surface, and the second sliding part 2012 has an inclined surface. When the connecting terminal 20 is inserted into the assembly channel 401, the arc surface or inclined surface of the plug end of the plug 201 will guide the plug 201 after contacting the assembly channel 401, which helps the plug 201 to be inserted into the assembly channel 401.

[0039] It should be noted that in other embodiments, when a third transition surface 402 is provided at one end of the third surface of the assembly channel 401, and the connecting terminal 20 is provided with a plug 201 having a first sliding part 2011 and a second sliding part 2012, during the process of inserting the connecting terminal 20 into the assembly channel 401, the first sliding part 2011 or the second sliding part 2012 contacts and enters the assembly channel 401 along the third transition surface 402, making the process of inserting the connecting terminal 20 into the assembly channel 401 more convenient, and improving the assembly efficiency of the base 10 and the housing 40.

[0040] In one embodiment of this application, reference is made to Figures 1 to 3 The first protrusion 30 extends to one side along or near the middle of the connecting terminal 20, further referring to... Figure 3 The first convex body 30 has a first transition surface 301. (Referring to...) Figure 1When the base 10 is assembled with the housing 40, the first protrusion 30 is positioned toward the tongue 50. In this way, the first transition surface 301 helps the first protrusion 30 to pass over the second protrusion 60, reducing the difficulty of fitting the connecting terminal 20 and the tongue 50 together.

[0041] In one embodiment of this application, reference is made to Figure 3 The first transition surface 301 is located on the side of the first protrusion 30 away from the first surface of the base 10. After the connecting terminal 20 is inserted into the assembly channel 401, the first transition surface 301 of the first protrusion 30 first contacts the second protrusion 60, which helps the first protrusion 30 to pass over the second protrusion 60 and achieve the locking of the two.

[0042] The first transition surface 301 is a sloped or arc-shaped surface. When the first protrusion 30 comes into contact with the second protrusion 60, the first transition surface 301, which is a sloped or arc-shaped surface, interacts with the second protrusion 60, causing the connecting terminal 20 to deform and pass over the second protrusion 60, reducing the difficulty for the first protrusion 30 to pass over the second protrusion 60 and facilitating the assembly of the connector.

[0043] In one embodiment of this application, reference is made to Figure 1 , Figure 2 and Figure 5 The second protrusion 60 is located at or near one end of the tongue 50 away from the housing 40, further referencing... Figure 5 The second convex body 60 has a second transition surface 601. (Referring to...) Figure 1 When the base 10 is assembled with the housing 40, the second protrusion 60 is positioned toward the connecting terminal 20. In this manner, the second transition surface 601 helps the first protrusion 30 to pass over the second protrusion 60, reducing the difficulty of the connecting terminal 20 and the tongue 50 fitting together.

[0044] In one embodiment of this application, reference is made to Figure 5 The second transition surface 601 is located on the side of the second protrusion 60 near the third surface of the housing 40. After the connecting terminal 20 is inserted into the assembly channel 401, the first protrusion 30 first contacts the second transition surface 601 of the second protrusion 60, which helps the first protrusion 30 to pass over the second protrusion 60 and achieve a snap-fit ​​locking between the two.

[0045] The second transition surface 601 is a sloped or arc-shaped surface. When the first protrusion 30 comes into contact with the second protrusion 60, the second transition surface 601, which is a sloped or arc-shaped surface, interacts with the first protrusion 30, causing the connecting terminal 20 to deform and pass over the second protrusion 60, reducing the difficulty for the first protrusion 30 to pass over the second protrusion 60 and facilitating the assembly of the connector.

[0046] Secondly, this application provides a connector assembly including the aforementioned multi-channel connector.

[0047] During the assembly of the base 10 and housing 40, the connecting terminal 20 passes through the housing 40 and moves along the second protrusion 60 of the tongue 50. When the first protrusion 30 contacts the second protrusion 60, the base 10 and housing 40 continue to move, causing the connecting terminal 20 to deform and allowing the first protrusion 30 to pass through the second protrusion 60. After the first protrusion 30 completely passes the second protrusion 60, it resets, and the first protrusion 30 and the second protrusion 60 abut against each other to achieve a locking engagement. The first protrusion 30 and the second protrusion 60 in the locked engagement state can provide locking force for the base 10 and housing 40. A tight connection between the first protrusion 30 and the second protrusion 60 can be achieved without using complex processes such as hot riveting and potting, which simplifies the connector assembly process, reduces the assembly difficulty of the connector, and improves the assembly efficiency of the connector. The overall structure of the connector is simple, reducing manufacturing costs and facilitating industrial production. The connector assembly of the multi-port connector also has the above advantages, which will not be elaborated here.

[0048] Thirdly, this application also provides an electronic device including the connector assembly described above.

[0049] Since electronic devices include connector assemblies, they also possess the aforementioned advantages, which will not be elaborated upon here.

[0050] The multi-channel connector, connector assembly, and electronic device provided in this application have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
