Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a USB connector with built-in detection function. Background Technology

[0002] With the rapid development of computer hardware, peripheral devices are increasing daily. Currently, USB electrical connectors are widely used in electronic products, serving as connectors or backup interfaces between components.

[0003] Existing USB connectors generally consist of a metal shell, a plastic body, and a signal terminal. When using them, users often encounter problems because the male connector cannot be effectively recognized when inserted, i.e., it is not inserted properly or there is no normal contact. This leads to abnormal recognition, making the connection between the male and female connectors unreliable and unsafe. As a result, users may mistakenly believe that there is a problem with the USB male connector in the connected device and discard it directly, which is detrimental to normal use.

[0004] Therefore, it is necessary to propose a USB connector with built-in detection function to detect the USB male connector during insertion, so as to effectively identify whether the insertion is in place and improve the reliability of the insertion. Utility Model Content

[0005] To address the aforementioned issues, this invention proposes a USB connector with built-in detection capabilities to detect the USB male connector during insertion, thereby effectively identifying whether the insertion is complete and improving the reliability of the insertion.

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a USB connector with built-in detection function, including a plug terminal board, a detection pin assembly, a protective shell assembly, and a PCB board. The protective shell assembly has a plug slot. The plug terminal board is fixedly connected to the protective shell assembly, and a portion of the plug terminal board is housed in the plug slot. The detection pin assembly is fixedly connected to both sides of the plug terminal board and extends into the plug slot. The PCB board is fixedly connected to one end of the protective shell assembly. The plug terminal board and the detection pin assembly are both electrically connected to the PCB board.

[0008] Furthermore, the detection pin assembly includes two contact pins, which are respectively fixedly connected to both sides of the plug-in terminal block. One end of each contact pin extends into the plug-in slot, and the other end of each contact pin passes through the protective shell assembly and is electrically connected to the PCB board.

[0009] Furthermore, both sides of the plug-in terminal block are provided with clamping and fixing parts, and the two clamping and fixing parts correspond one-to-one with the two contact pins, and one side of the contact pin is fixedly connected to the clamping and fixing parts.

[0010] Furthermore, the clamping and fixing part is provided with a clamping groove, and the contact pin is provided with a connecting plate, which is received in the clamping groove and abuts against the groove wall of the clamping groove.

[0011] Furthermore, the clamping and fixing part is provided with an embedding groove, which is connected to the clamping groove, and the connecting plate is provided with an embedding post, which is received in the embedding groove and abuts against the groove wall of the embedding groove.

[0012] Furthermore, the clamping groove is provided with a boss, and the connecting plate is provided with a snap-fit ​​protrusion structure, which abuts against the boss.

[0028] PCB board 4. Detailed Implementation

[0029] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model.

[0030] Please refer to Figures 1-5 This utility model proposes a USB connector with built-in detection function, including a plug terminal board 1, a detection pin assembly 2, a protective shell assembly 3, and a PCB board 4. The plug terminal board 1 can be a 4-pin terminal board or a 5-pin terminal board, depending on the requirements. The protective shell assembly 3 has a plug slot 301. The plug terminal board 1 is fixedly connected to the protective shell assembly 3, and a part of the plug terminal board 1 is housed in the plug slot 301. The detection pin assembly 2 is fixedly connected to both sides of the plug terminal board 1 and extends into the plug slot 301. The PCB board 4 is fixedly connected to one end of the protective shell assembly 3. The plug terminal board 1 and the detection pin assembly 2 are both electrically connected to the PCB board 4.

[0031] In this embodiment, detection pin assemblies 2 are installed on both sides of the connector terminal block 1. Then, the connector terminal block 1 with the detection pin assemblies 2 is installed inside the protective housing assembly 3, which protects the connector terminal block 1. The PCB board 4 serves as the electrical connection structure between the connector terminal block 1 and the detection pin assemblies 2. After electrical connection, the detection pin assemblies 2 and the PCB board 4 form a conductive loop to be contacted. A module for monitoring this loop is provided on the PCB board 4, or a module for monitoring this loop is provided on the device side. (USB public...) When the USB male connector is inserted into the socket 301 and contacts the terminal block 1, the detection pin assembly 2 will contact the metal shell of the USB male connector and form a conductive circuit. At this time, it is confirmed that the USB male connector has been successfully inserted into place, and the power supply of the terminal block 1 will be turned on to enable power supply and signal transmission with the USB male connector. If the USB male connector does not contact the detection pin assembly 2 and does not form a circuit, the power supply of the terminal block 1 will not be turned on, which means that the USB male connector is not inserted into place.

[0032] In summary, this USB connector with built-in detection function can effectively detect the USB male connector during insertion, thereby effectively identifying whether the insertion is in place and improving the reliability of the insertion.

[0033] In this embodiment, the detection pin assembly 2 includes two contact pins 21, which are symmetrically arranged and fixedly connected to both sides of the plug-in terminal board 1. One end of each contact pin 21 extends into the plug-in slot 301, and the other end of each contact pin 21 passes through the protective shell assembly 3 and is electrically connected to the PCB board 4. The two contact pins 21 are used to contact the outer shell of the USB male connector to form a conductive circuit. When the USB male connector is successfully inserted into place, both sides of the outer shell of the USB male connector contact the two contact pins 21 respectively. At this time, the power supply of the plug-in terminal board 1 will be turned on to power on the USB male connector and transmit signals.

[0034] In this embodiment, the plug-in terminal block 1 is provided with clamping and fixing parts 11 on both sides. The two clamping and fixing parts 11 correspond one-to-one with the two contact pins 21. One side of the contact pin 21 is fixedly connected to the clamping and fixing part 11. When installing the two contact pins 21, the contact pins 21 need to be pressed towards the clamping and fixing part 11 so that the contact pins 21 are fixed in the clamping and fixing part 11.

[0035] In this embodiment, the clamping and fixing part 11 is provided with a clamping groove 111, and the contact pin 21 is provided with a connecting plate 211. The connecting plate 211 is received in the clamping groove 111 and abuts against the groove wall of the clamping groove 111. When the contact pin 21 is installed on the clamping and fixing part 11, the connecting plate 211 is aligned with the clamping groove 111 and pressed, so that the connecting plate 211 is embedded in the clamping groove 111. At this time, the contact pin 21 is successfully installed and fixed.

[0036] In this embodiment, the clamping and fixing part 11 is provided with an embedding groove 112, which is connected to the clamping groove 111. The connecting plate 211 is provided with an embedding post 2111, which is received in the embedding groove 112 and abuts against the groove wall of the embedding groove 112. In order to increase the stability of the installation of the connecting plate 211, an embedding post 2111 is required for auxiliary fixing. During installation, the embedding post 2111 needs to be aligned with the embedding groove 112 and then pressed down so that the embedding post 2111 is inserted into the embedding groove 112 for fixing.

[0037] In this embodiment, a boss 1111 is provided in the clamping groove 111, and a snap-fit ​​protrusion 2112 is provided on the connecting plate 211. The snap-fit ​​protrusion 2112 abuts against the boss 1111. After the connecting plate 211 is embedded in the clamping groove 111, in order to ensure that the contact pin 21 has a certain elasticity, the snap-fit ​​protrusion 2112 is provided to abut against the boss 1111, so that one end of the contact pin 21 is slightly raised, which improves the elasticity of one end of the contact pin 21. This facilitates elastic recovery when the contact pin 21 contacts the outer shell of the USB male connector, and elastic restoration when the outer shell of the USB male connector is pulled out.

[0038] In this embodiment, the clamping and fixing part 11 is provided with a receiving groove 113, and one end of the contact pin 21 is provided with an elastic contact plate 212. A part of the elastic contact plate 212 is received in the receiving groove 113, and the other part of the elastic contact plate 212 extends into the insertion groove 301. After the contact pin 21 is fixed in the clamping and fixing part 11, the elastic contact plate 212 will be received in the receiving groove 113 and extend into the insertion groove 301. The receiving groove 113 is used to provide a space for the elastic retraction or elastic recovery of the elastic contact plate 212.

[0039] In this embodiment, the elastic contact plate 212 is provided with a bent structure 2121, which extends into the insertion slot 301. The bent structure 2121 facilitates the extension into the insertion slot 301 and also facilitates contact with the housing of the USB male connector.

[0040] In this embodiment, the protective shell assembly 3 includes a fixed shell 31, a first wrapping shell 32, and a second wrapping shell 33. The insertion slot 301 is located inside the fixed shell 31. The insertion terminal board 1 is fixedly connected inside the fixed shell 31. One end of the insertion terminal board 1 and one end of the detection pin assembly 2 both penetrate the fixed shell 31. The first wrapping shell 32 wraps around one side of the fixed shell 31 and forms a snap-fit ​​connection with the fixed shell 31. The second wrapping shell 33 wraps around one side of the first wrapping shell 32 and forms a snap-fit ​​connection with the first wrapping shell 32. When assembling this utility model on the production line, the insertion terminal board 1 is first installed inside the fixed shell 31. Then, the first wrapping shell 32 is wrapped around one side of the fixed shell 31 by a bending device. Then, the second wrapping shell 33 is wrapped around one side of the first wrapping shell 32 by a bending device. Under the double wrapping of the first wrapping shell 32 and the second wrapping shell 33, the stability of the protective shell assembly 3 is improved, which is conducive to the stable insertion of the USB male connector.

[0041] In this embodiment, the fixed housing 31 is provided with an embedded mounting part 311, and the plug-in terminal board 1 is provided with a connecting part 12. The connecting part 12 is fixedly connected to the embedded mounting part 311. The embedded mounting part 311 is provided with a plurality of fixing grooves 3111 and a plurality of clearance grooves 3112. The connecting part 12 is provided with a plurality of embedded bosses 121. The plurality of embedded bosses 121 correspond one-to-one with the plurality of fixing grooves 3111. The embedded bosses 121 are embedded in the fixing grooves 3111 for fixation. When the plug-in terminal board 1 is installed on the fixed housing 31, the plurality of embedded bosses 121 are aligned with the plurality of fixing grooves 3111 and then embedded and fixed. During the embedding and fixing process, the plurality of pins on the plug-in terminal board 1 pass through the plurality of clearance grooves 3112 respectively. One end of the two contact pins 21 also passes through the two clearance grooves 3112. Then, they are all fixedly connected and electrically connected to the PCB board 4 by soldering.

[0042] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
