Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and more particularly to a connector and a circuit board assembly adapted to the connector. Background Art

[0002] Connectors are widely used in various fields, including automobiles, communications, computers, consumer electronics, industry, and transportation. Applicable vehicle types include new energy vehicles, electric bicycles, electric motorcycles, and electric scooters. Connector plugs and sockets, as key components, bridge communication between circuits, allowing current to flow and enabling the circuit to perform its intended function. Existing connectors have one end for insertion and the other end with a solder cup for bonding wires to the circuit board. However, the connector mounting holes are relatively small, and the internal wiring may not be precisely positioned within the mounting hole. If misaligned, disassembly is impossible, requiring the entire circuit board to be removed for replacement, leading to inconvenient repairs and high costs. Utility Model Content

[0003] The purpose of this application is to provide a connector.

[0004] This application provides a connector, comprising a connector core and at least one first conductive terminal. The connector core has at least one first mounting hole, which extends through both ends of the connector core along the insertion / removal direction of the connector. The first conductive terminal is positioned in the first mounting hole and includes a first sleeve and a first pin located at opposite ends thereon. The first sleeve is located at one end of the first mounting hole and includes a resilient first gripping portion. The first pin is located at the opposite end of the first mounting hole and includes a resilient first insertion portion. The first sleeve is used to mate with an external end to be inserted, and the first gripping portion positions the end to be inserted. The first pin is used to mate with an external hole to be inserted, and the first insertion portion is positioned against the wall of the hole to be inserted.

[0005] This application also provides a circuit board assembly, which includes a connector and a circuit board. The connector is electrically connected to and fixedly connected to the circuit board. The connector has a connection hole, and the first insertion portion of the first conductive terminal of the connector is inserted into the connection hole.

[0006] The connector of this application can be used in electronic products, such as batteries.

[0052] In this design, the outer peripheral surface of the second barb 313 sealably abuts against the inner peripheral surface of the second mounting hole 112, the second positioning boss 311 is positioned on the second positioning step 1123, and the second adhesive receiving groove 312 is positioned on the potting cavity 131, with the second adhesive receiving groove 312 communicating with the potting cavity 131. By providing the second barb 313 to sealably abut against the inner peripheral surface of the second mounting hole 112, and by providing the second positioning boss 311 to be positioned on the second positioning step 1123, the second conductive terminal 300 can be more firmly fixed to the connector core 100, and the sealing performance between the second conductive terminal 300 and the connector core 100 is improved. In other embodiments, the second positioning boss 311, the second positioning step 1123, and the second barb 313 can all be omitted.

[0053] The third conductive terminal 400 is positioned in the third mounting hole 113, the third sleeve 420 is located at one end of the third mounting hole 113, and the third pin 430 is located at the opposite end of the third mounting hole 113. Specifically, the third conductive terminal 400 passes through the potting cavity 131 and the third mounting hole 113 in sequence. The third sleeve 420 is positioned in the third mounting hole 113, a portion of the third positioning part 410 is positioned in the third mounting hole 113, and another portion is positioned in the potting cavity 131. The third pin 430 is positioned on the outside of the potting cavity 131.

[0054] In this design, the outer peripheral surface of the third barb 413 sealably abuts against the inner peripheral surface of the third mounting hole 113, the third positioning boss 411 is positioned on the third positioning step 1133, and the third adhesive receiving groove 412 is positioned within the potting cavity 131, communicating with the potting cavity 131. By providing the third barb 413 to sealably abut against the inner peripheral surface of the third mounting hole 113, and by providing the third positioning boss 411 to be positioned on the third positioning step 1133, the third conductive terminal 400 can be more firmly fixed to the connector core 100, and the sealing performance between the third conductive terminal 400 and the connector core 100 is improved. In other embodiments, the third positioning boss 411, the third positioning step 1133, and the third barb 413 can all be omitted.

[0055] The following describes the assembly method of connector 1000: First, insert the first sleeve 220 of the first conductive terminal 200 into the first mounting hole 111 and push the first conductive terminal 200 until the first positioning boss 211 abuts against the first positioning step 1113; Second, insert the second sleeve 320 of the second conductive terminal 300 into the second mounting hole 112 and push the second conductive terminal 300 until the second positioning boss 311 abuts against the second positioning step 1123; Third, insert the third sleeve 420 of the third conductive terminal 400 into the third mounting hole 113 and push the third conductive terminal 400 until the third positioning boss 411 abuts against the third positioning step 1133; Fourth, inject glue into the glue potting cavity 131.

[0056] After the adhesive solidifies, it forms a positioning adhesive 500, which allows the first conductive terminal 200, the second conductive terminal 300, and the third conductive terminal 400 to be more securely installed on the connector core 100. Additionally, when the adhesive enters the potting cavity 131, it also fills the first adhesive reservoir 212 of the first conductive terminal 200, the second adhesive reservoir 312 of the second conductive terminal 300, and the third adhesive reservoir 412 of the third conductive terminal 400. The solidified positioning adhesive 500, after entering the first adhesive reservoir 212, the second adhesive reservoir 312, and the third adhesive reservoir 412, provides a limiting effect on the first conductive terminal 200, the second conductive terminal 300, and the third conductive terminal 400, further securing them to the connector core 100. In other embodiments, the positioning colloid 500, the first glue container 212, the second glue container 312, the third glue container 412, and the glue filling cavity 131 can all be omitted.

[0057] In this embodiment, the first sleeve 220 is adapted to an external end to be inserted, and the first gripping part 221 positions the end to be inserted. The first pin 230 is adapted to an external hole to be inserted, and the first clamping part 231 is positioned on the wall of the hole to be inserted. The second sleeve 320 is adapted to another external end to be inserted, and the second gripping part 321 positions the other end to be inserted. The second pin 330 is adapted to another external hole to be inserted, and the second clamping part 331 is positioned on the wall of the other hole to be inserted.

The third pin 430 is adapted to another external hole to be inserted, and the third clamping part 431 is positioned on the wall of the other hole to be inserted.

[0058] For example, one end of connector 1000 is used to plug into a socket of an external power source, and the other end of connector 1000 is used to plug into the circuit board assembly 2000 of the battery of an electronic product, so as to realize the electrical connection between the battery and the power source, thereby realizing the charging of the battery.

[0059] The first connecting portion 110 of the connector 1000 is inserted into the socket of the power supply end. The first plug-in end of the socket of the power supply end is inserted into the first plug-in hole 2212 of the first sleeve 220 and abuts against a plurality of first elastic gripping strips 2211. The plurality of first elastic gripping strips 2211 expand outward to generate elastic force. The plurality of elastic forces act on the first plug-in end, that is, the plurality of first elastic gripping strips 2211 elastically clamp the first plug-in end, so that the first plug-in end and the first sleeve 220 are electrically connected and fixedly connected. It can be understood that the end to be plugged in (i.e., the first plug-in segment of the socket of the power supply end) can be positioned in the first plug-in hole 2212 of the first sleeve 220.

[0060] By setting the first elastic gripping bar 2211, the structure is simple and the cost is low. When multiple first elastic gripping bars 2211 are arranged at even intervals around the circumference of the first sleeve 220, the elastic force generated by the multiple first elastic gripping bars 2211 is more uniform, making the connection of the connector 1000 more stable.

[0061] The second plug-in end of the power socket is inserted into the second plug-in hole 3212 of the second sleeve 320 and abuts against multiple second elastic gripping strips 3211. The multiple second elastic gripping strips 3211 expand outward to generate elastic force, which acts on the second plug-in end, that is, the multiple second elastic gripping strips 3211 elastically clamp the second plug-in end, so that the second plug-in end and the second sleeve 320 are electrically connected and fixedly connected. It can be understood that another plug-in end (i.e., the second plug-in end of the power socket) can be positioned in the second plug-in hole 3212.

[0062] By incorporating the second elastic gripping bar 3211, the structure is simple and the cost is low. When multiple second elastic gripping bars 3211 are arranged at even intervals around the circumference of the second sleeve 320, the elastic force generated by the multiple second elastic gripping bars 3211 is more uniform, making the connection of the connector 1000 more stable.

[0063] The third plug-in end of the power socket is inserted into the third plug-in hole 4212 of the third sleeve 420 and abuts against multiple third elastic gripping strips 4211. The multiple third elastic gripping strips 4211 expand outward to generate elastic force, which acts on the third plug-in end, that is, the multiple third elastic gripping strips 4211 elastically clamp the third plug-in end, so that the third plug-in end and the third sleeve 420 are electrically connected and fixedly connected. It can be understood that another plug-in end (i.e., the third plug-in end of the power socket) can be positioned in the third plug-in hole 4212.

[0064] By incorporating a third elastic gripping bar 4211, the structure is simple and the cost is low. When multiple third elastic gripping bars 4211 are arranged at even intervals around the circumference of the third sleeve 420, the elastic force generated by the multiple third elastic gripping bars 4211 is more uniform, making the connection of the connector 1000 more stable.

[0065] Please refer to Figure 8 and Figure 9 The first pin 230, the second pin 330, and the third pin 430 of the connector 1000 are inserted into the circuit board assembly 2000 to achieve electrical and fixed connection between the connector 1000 and the circuit board assembly 2000. Specifically, the circuit board assembly 2000 includes a circuit board 2100, a connector 2200, and an adapter 2300. The circuit board 2100 is provided with a signal hole 2101, a power hole 2102, and a current hole 2103. The signal hole 2101 penetrates the circuit board 2100 along its thickness direction, and a conductive contact pad 2104 is provided on the inner peripheral surface of the signal hole 2101. In this embodiment, the number of signal holes 2101 is five. In other embodiments, the number of signal holes 2101 can be one, two, three, four, six, or more.

[0066] A power supply hole 2102 penetrates the circuit board 2100 along its thickness direction. A connector 2200, which is a copper sleeve, is provided within the power supply hole 2102. The connector 2200 includes a connecting section 2201 and a positioning section 2202 that are fixedly connected. The connecting section 2201 and the positioning section 2202 are coaxially designed, and a stepped surface 2203 is provided between them. Specifically, the diameter of the connecting section 2201 is larger than the diameter of the positioning section 2202, thus forming the stepped surface 2203 between them. The connector 2200 also has a connecting hole 2204. One end of the connecting hole 2204 penetrates the end face of the connecting section 2201 facing away from the positioning section 2202, and the other end of the connecting hole 2204 penetrates the end face of the positioning section 2202 facing away from the connecting section 2201. The positioning segment 2202 of the connector 2200 extends into the power hole 2102 and is soldered to the pad on the back of the power hole 2102 to achieve electrical and fixed connection. This design is simple in structure, easy to assemble, and thus reduces cost. In other embodiments, the positioning segment 2202 of the connector 2200 can be interference-fitted with the power hole 2102. This design also has the advantages of simple structure, easy assembly, and low cost. The stepped surface 2203 of the connector 2200 abuts against the surface of the circuit board 2100 for positioning. In this embodiment, there are two power holes 2102 and two connectors 2200. In other embodiments, there can be one, three, or more power holes 2102 and connectors 2200.

[0067] A current via 2103 penetrates the circuit board 2100 along its thickness direction. An adapter 2300, which is a copper sleeve, is housed within the current via 2103. The adapter 2300 includes a fixedly connected adapter section 2301 and a mounting section 2302. The adapter section 2301 and the mounting section 2302 are coaxially designed, and a positioning surface 2303 is provided between them. Specifically, the diameter of the adapter section 2301 is larger than the diameter of the mounting section 2302, thus forming the positioning surface 2303 between them. The adapter 2300 also has an adapter hole 2304. One end of the adapter hole 2304 penetrates the end face of the adapter section 2301 facing away from the mounting section 2302, and the other end of the adapter hole 2304 penetrates the end face of the mounting section 2302 facing away from the adapter section 2301. The mounting section 2302 of the adapter 2300 extends into the current via 2103 and is soldered to the pad on the back of the current via 2103 to achieve electrical and fixed connection. This design is simple in structure, easy to assemble, and thus reduces cost. In other embodiments, the mounting section 2302 of the adapter 2300 can be interference-fitted with the current via 2103; this design also offers the advantages of simple structure, easy assembly, and low cost. The positioning surface 2303 of the adapter 2300 abuts against the surface of the circuit board 2100 for positioning. In this embodiment, there is one current via 2103 and one adapter 2300. In other embodiments, there can be two or more current vias 2103 and adapters 2300.

[0068] The pins of connector 1000 are inserted into connection holes 2204. Specifically, the first insertion portion 231 of the first pin 230 of connector 1000 is inserted into the connection hole 2204 of connector 2200. Since the diameter of the first insertion portion 231 is larger than the diameter of the connection hole 2204, and there are first clearance holes 2312 and second clearance grooves 2313 between the plurality of first elastic clamping strips 2311, when the first insertion portion 231 is inserted into the connection hole 2204, the first insertion portion 23... The multiple first elastic clamping strips 2311 of component 1 retract toward the first clearance hole 2312 and the second clearance groove 2313. Each of the multiple first elastic clamping strips 2311 generates elastic force, which acts on the wall of the connecting hole 2204. That is, the multiple first elastic clamping strips 2311 elastically abut against the wall of the connecting hole 2204 to achieve electrical and fixed connection between the first pin 230 and the connector 2200, thereby achieving electrical connection between the first pin 230 and the circuit board 2100. The outer diameter of the first clamping portion 231 at the end away from the first sleeve 220 is larger than the outer diameter of the first clamping portion 231 at the end near the first sleeve 220. In this embodiment, the outer diameter of the first clamping portion 231 gradually increases from the end near the first sleeve 220 to the end away from the first sleeve 220. It is understandable that when the first insertion part 231 is positioned on the wall of the hole to be inserted (i.e., the connecting hole 2204), the first elastic insertion bar 2311 elastically abuts against the wall of the hole to be inserted (i.e., the connecting hole 2204), and the outer diameter of the first insertion part 231 becomes smaller.

[0069] By setting the first elastic clamping bar 2311, the structure is simple and the cost is low. When multiple first elastic clamping bars 2311 are arranged evenly around the circumference of the first pin 230, the elastic force generated by the multiple first elastic clamping bars 2311 is more uniform, making the connection of the connector 1000 more stable.

[0070] The second insertion portion 331 of the second pin 330 of connector 1000 is inserted into the signal hole 2101 of circuit board 2100. Since the diameter of the second insertion portion 331 is larger than the diameter of the signal hole 2101, and there are second clearance holes 3312 and fourth clearance grooves 3313 between the multiple second elastic insertion strips 3311, when the second pin 330 is inserted into the signal hole 2101, the multiple second elastic insertion strips 3311 of the second insertion portion 331 will shrink toward the second clearance holes 3312 and the fourth clearance grooves 3313. The multiple second elastic insertion strips 3311 generate elastic force, and the multiple elastic forces act on the conductive contact plate 2104 of the signal hole 2101. That is, the multiple second elastic insertion strips 3311 elastically abut against the conductive contact plate 2104 of the signal hole 2101 to realize the electrical connection and fixed connection between the second pin 330 and circuit board 2100. It is understandable that when the second insertion part 331 is positioned on the wall of another insertion hole (i.e., signal hole 2101), the second elastic insertion bar 3311 elastically abuts against the wall of the other insertion hole (i.e., signal hole 2101), and the outer diameter of the second insertion part 331 becomes smaller.

[0071] By incorporating a second elastic clamping bar 3311, the structure is simple and the cost is low. When multiple second elastic clamping bars 3311 are arranged at even intervals around the circumference of the second pin 330, the elastic force generated by the multiple second elastic clamping bars 3311 is more uniform, making the connection of the connector 1000 more stable.

[0072] The third insertion portion 431 of the third pin 430 of connector 1000 is inserted into the adapter hole 2304 of adapter 2300. Since the diameter of the third insertion portion 431 is larger than the diameter of the adapter hole 2304, and there are third clearance holes 4312 and sixth clearance grooves 4313 between the multiple third elastic insertion strips 4311, when the third insertion portion 431 is inserted into the adapter hole 2304, the multiple third elastic insertion strips 431 of the third insertion portion 431... 11 will retract toward the third clearance hole 4312 and the sixth clearance groove 4313, and multiple third elastic clamping strips 4311 will generate elastic force. Multiple elastic forces act on the hole wall of the adapter hole 2304, that is, multiple third elastic clamping strips 4311 elastically abut against the hole wall of the adapter hole 2304, so as to realize the electrical connection and fixed connection between the third pin 430 and the adapter 2300, and thus realize the electrical connection between the third pin 430 and the circuit board 2100. It can be understood that when the third clamping part 431 is positioned on the hole wall of another hole to be inserted (i.e., adapter hole 2304), the third elastic clamping strip 4311 elastically abuts against the hole wall of the other hole to be inserted (i.e., adapter hole 2304), and the outer diameter of the third clamping part 431 becomes smaller.

[0073] By incorporating a third elastic clamping bar 4311, the structure is simple and the cost is low. When multiple third elastic clamping bars 4311 are arranged at even intervals around the circumference of the third pin 430, the elastic force generated by the multiple third elastic clamping bars 4311 is more uniform, making the connection of the connector 1000 more stable.

[0074] In this embodiment, the connector 1000 eliminates the solder cup structure, and both ends of the connector 1000 are provided with plug-in structures, so both ends can be plugged in. Therefore, the connector 1000 and the circuit board assembly 2000 can be electrically connected and fixedly connected through plugging in, which is easy to disassemble and convenient for maintenance, thereby reducing costs.

[0075] In this embodiment, the first conductive terminal is provided with an elastic first gripping part and an elastic first insertion part at both ends. When the first gripping part is inserted into the insertion end of the socket, the first gripping part undergoes elastic deformation and generates elastic force. When the first insertion part is inserted into the insertion hole of the circuit board assembly, the first insertion part undergoes elastic deformation and generates elastic force, making the connection between the connector and the socket and circuit board assembly 2000 at the power end more stable, and the structure is simple and the cost is low.

[0076] In some other embodiments, the first insertion portion 231 of the first conductive terminal 200, the second insertion portion 331 of the second conductive terminal 300, and the third insertion portion 431 of the third conductive terminal 400 can all be configured as a fisheye structure or a twisted elastic pin.

[0077] In this embodiment, by designing a second conductive terminal 300 for signal transmission and setting a third conductive terminal 400 for small current transmission, the connector 1000 becomes more functional.

[0078] In this embodiment, when the first insertion part 231 of the first conductive terminal 200 is inserted into the connection hole 2204, the first guide surface 2314 of the first insertion part 231 is guided; when the second insertion part 331 of the second conductive terminal 300 is inserted into the signal hole 2101, the second guide surface 3314 of the second insertion part 331 is guided; and when the third insertion part 431 of the third conductive terminal 400 is inserted into the adapter hole 2304, the third guide surface 4314 of the third insertion part 431 is guided, making it easier for the connector 1000 to be inserted.

[0079] In this embodiment, since the second conductive terminal 300 is directly plugged into the signal hole 2101 on the circuit board 2100, the structure is simple and the cost is low. Since both the power hole 2102 and the current hole 2103 adopt copper sleeve structure power sockets, the raw material cost and processing cost of the power sockets are significantly reduced. Furthermore, since a part of the connector 2200 and a part of the adapter 2300 are embedded in the circuit board 2100, it is beneficial to reduce the coupling height between the connector 1000 and the circuit board assembly 2000.

[0080] In this embodiment, since the outer diameter of the first insertion part 231 gradually increases from the end near the first sleeve 220 to the end away from the first sleeve 220, when the first insertion part 231 is positioned on the wall of the hole to be inserted (i.e. the connection hole 2204), the deformation of the end with the larger diameter of the first insertion part 231 is larger, which makes the elastic force generated by the first insertion part 231 greater, thereby making the connection stability of the connector 1000 better.

[0081] The design of the outer diameter of the second insertion part 331 gradually increasing from the end near the second sleeve 320 to the end away from the second sleeve 320, and the design of the outer diameter of the third insertion part 431 gradually increasing from the end near the third sleeve 420 to the end away from the third sleeve 420, have the same technical effect, and will not be elaborated on here.

[0082] In this embodiment, the diameter of the fixing hole 121 can be set to be relatively large. Since the connector 1000 and the circuit board assembly 2000 are positioned by terminal coupling, and the circuit board assembly 2000 and the connector 1000 mounting panel are usually two pieces, due to machining accuracy errors, it is not easy for the connector 1000 mounting panel and the circuit board assembly 2000 to be aligned. If the fixing hole 121 of the connector 1000 cannot compensate for the positional deviation between the circuit board assembly 2000 and the connector 1000 mounting panel, it will cause the terminals of the connector 1000 and the circuit board assembly 2000 to be stressed, which will greatly reduce the service life of the product.

[0083] In some embodiments, please refer to Figure 10 The connector 1000 also includes a sealing gasket 600, which is a rectangular plate. The sealing gasket 600 has a through hole 601 in the middle and through holes 602 at the four corners. The second connecting part 130 passes through the through hole 601. The sealing gasket 600 is attached to the surface of the fixing part 120 facing the second connecting part 130. The four through holes 602 of the sealing gasket 600 are respectively aligned with the four fixing holes 121 of the fixing part 120.

[0084] When using connector 1000, connector 1000 is installed in the housing of electronic device. The second connecting portion 130 of connector 1000 extends into the housing. Sealing gasket 600 is clamped between the housing and fixing portion 120. Four locking fasteners pass through the four fixing holes 121 of fixing portion 120 and the four through holes 602 of sealing gasket 600 respectively and are then locked to the housing. Sealing gasket 600 can seal the gap between fixing portion 120 and housing.
