Technical Field
[0001] This application relates to the technical field of sockets, and more particularly to a socket with a USB connector. Background Technology
[0002] A socket is a power connection interface device used by electrical appliances to connect to the power grid and obtain electrical energy. Sockets usually have circuit boards, which are used to connect electrical components in the circuit. Circuit boards usually have switching power supply chips and MOSFETs.
[0003] In related technologies, the socket includes a housing, a placement cavity is provided inside the housing, a circuit board is provided inside the housing, and a chip and a MOSFET are provided on the circuit board. The MOSFET and the chip can abut against the inner wall of the placement cavity.
[0004] Because the chip and MOSFET generate heat when they are working, and both the chip and MOSFET are in contact with the inner wall of the placement cavity, it is difficult for the chip and MOSFET to dissipate heat directly, resulting in poor heat dissipation of the circuit board and making it difficult for the socket to be used for a long time. Utility Model Content
[0005] To improve the heat dissipation problem of MOSFETs, this application provides a socket with a USB connector.
[0006] This application provides a socket with a USB connector, which adopts the following technical solution:
[0007] A socket with a USB connector includes a housing with a placement cavity, a USB connector on the housing, a circuit board on the housing, a MOSFET and a switching power supply chip on the circuit board, and thermal silicone on the housing that abuts against the MOSFET and the switching power supply chip.
[0008] By adopting the above technical solution, the heat in the MOSFET and the switching power supply chip is dispersed by the thermal silicone, which prevents the MOSFET from overheating and affecting the performance of the switching power supply chip, thus ensuring the normal use of the socket.
[0009] Optionally, the housing is provided with heat dissipation holes that communicate with the placement cavity.
[0010] By adopting the above technical solution, the heat in the thermal silicone can be directly exchanged with the outside air through the heat dissipation holes connected to the placement cavity, thereby further improving the heat dissipation efficiency of the thermal silicone.
[0011] Optionally, the housing includes an upper shell and a lower shell, the upper shell is assembled on the lower shell, the upper shell has a mounting groove, the lower shell has a mounting hole, and the lower shell has a mounting bolt; when the mounting bolt passes through the mounting hole and is threaded into the mounting groove, the upper shell and the lower shell are fixed to each other.
[0012] By adopting the above technical solution, the mounting bolts are threaded through the mounting holes and connected to the mounting grooves, thereby fixing the upper and lower shells and making the upper and lower shells more secure.
[0013] Optionally, the lower shell is provided with a guide block, and the upper shell is provided with a guide groove for the guide block to be inserted; when the guide block is located in the guide groove, the mounting hole is aligned with the mounting groove.
[0014] By adopting the above technical solution, the guide block is inserted into the guide groove so that the mounting hole can be aligned with the mounting groove, so that the upper shell and the lower shell can be pre-fixed, allowing the workers to quickly assemble the upper shell and the lower shell.
[0015] Optionally, the upper shell includes a panel, a protective shell, and a fixing shell. The protective shell is located between the panel and the fixing shell, and the fixing shell is disposed on the lower shell. The mounting groove is formed on the protective shell, and the fixing shell has a through hole for the mounting bolt to pass through. The protective shell has a limiting hole, and the wall of the limiting hole has a limiting groove. The panel has an elastic limiting block. When the limiting block is located in the limiting groove, the panel is fixed to the protective shell.
[0016] By adopting the above technical solution, workers can first install the circuit board and other structures on the fixed shell, and then assemble the protective shell and the fixed shell. The protective shell and the fixed shell protect the circuit board and other structures, reducing external damage to the circuit board. Because the limiting block is elastic, it can move smoothly from the limiting hole to the limiting groove, so that the panel is fixed on the protective shell, increasing the reliability between the panel and the protective shell.
[0017] Optionally, the protective shell is provided with a receiving strip, and the panel is provided with a placement groove for inserting the protective shell and a receiving groove for inserting the receiving strip; when the protective shell is located in the placement groove, the receiving strip is located in the receiving groove.
[0018] By adopting the above technical solution, when the panel is installed on the protective shell, the protective shell is located in the placement groove, and the receiving strip is located in the receiving groove, so that the receiving strip limits the panel, reduces the possibility of the panel sliding on the protective shell, and increases the reliability between the panel and the protective shell.
[0019] Optionally, the fixing shell is provided with a fixing spring, the protective shell is provided with a fixing hole for the fixing spring to pass through, and the protective shell is provided with a groove for the fixing spring to be inserted; when the fixing spring passes through the fixing hole and is inserted into the groove, the fixing shell and the protective shell are fixed to each other.
[0020] By adopting the above technical solution, the fixing spring passes through the fixing hole. Due to the elasticity of the fixing spring, it can be smoothly inserted into the groove, thereby allowing the fixing spring to position the protective shell and reducing the possibility of the fixing spring directly detaching from the fixing hole. This enables the fixing spring to fix the fixing shell and the protective shell to each other.
[0021] Optionally, a stop block is slidably connected to the panel, and the insertion path of the receiving strip and the movement path of the stop block intersect; when the receiving strip is inserted into the receiving groove, the stop block abuts against the side of the fixing spring away from the groove.
[0022] By adopting the above technical solution, when the receiving strip is inserted into the receiving groove, the insertion path of the receiving strip and the moving path of the stop block intersect, so that the receiving strip can drive the stop block to move, and the stop block is located on the side of the fixing spring away from the groove, so that the stop block restricts the fixing spring from detaching from the groove, and further increases the reliability between the fixing spring and the protective shell.
[0023] Optionally, a receiving slope is formed on the surface of the receiving strip facing the stop block, and the distance between the receiving slope and the fixed shell gradually decreases along the direction from the receiving strip to the stop block, and the receiving slope can abut against the stop block.
[0024] By adopting the above technical solution, the distance between the receiving inclined surface and the fixed shell gradually decreases along the direction from the receiving strip to the stop block. When the receiving strip is inserted into the receiving groove, the receiving inclined surface can drive the stop block to move, allowing the stop block to move smoothly to the side of the fixed spring piece away from the bottom wall of the groove.
[0025] Optionally, the switching power supply chip and the MOSFET are separate components, with a gap between them.
[0026] By adopting the above technical solution, both the switching power supply chip and the MOSFET generate heat when the socket is working. By separating the switching power supply chip and the MOSFET and spacing them together, the impact of the MOSFET on the switching power supply chip is reduced. In addition, the MOSFET can be replaced with a MOSFET with lower internal resistance to reduce the temperature.
[0027] In summary, this application includes at least one of the following beneficial technical effects:
[0028] 1. By using thermal silicone to contact the MOSFET and the switching power supply chip, the heat in the MOSFET and the switching power supply chip can be dispersed by the thermal silicone, so that the MOSFET is less likely to overheat and affect the performance of the switching power supply chip, thus ensuring the normal use of the socket.
[0029] 2. The staff can first install the circuit board and other structures on the fixed shell, and then assemble the protective shell and the fixed shell. The protective shell and the fixed shell protect the circuit board and other structures, reducing external damage to the circuit board. Because the limiting block is elastic, the limiting block can move smoothly from the limiting hole to the limiting groove, so that the panel is fixed on the protective shell, increasing the reliability between the panel and the protective shell.

[0038] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0039] Example 1
[0040] This embodiment discloses a socket with a USB connector. (Refer to...) Figure 1 and Figure 2 A socket with a USB connector includes a housing 1, which comprises an upper housing 11 and a lower housing 2. The upper housing 11 includes a panel 3, a protective housing 4, and a fixing housing 5. The panel 3 is mounted on the protective housing 4, the protective housing 4 is mounted on the fixing housing 5, and the fixing housing 5 can be mounted on the lower housing 2, i.e., the protective housing 4 is located between the panel 3 and the fixing housing 5. The panel 3 has an interface for inserting a USB connector, which is also provided on the protective housing 4 and the fixing housing 5.
[0041] Reference Figure 2 and Figure 3 A circuit board 12 is mounted on the housing 1, and the circuit board 12 is fixedly connected to the fixed housing 5, with the interface communicating with the circuit board 12. A MOSFET and a switching power supply chip are fixedly connected to the circuit board 12, wherein the MOSFET and the switching power supply chip are separately configured and have a certain spacing between them. The heat generated by the MOSFET can also be reduced by replacing it with a MOSFET with a lower internal resistance.
[0042] Reference Figure 2 and Figure 3 The lower shell 2 has a placement cavity 21 for housing the circuit board 12 and the fixing shell 5. Thermal silicone 22 is fixedly connected to the inner wall of the placement cavity 21, and the thermal silicone 22 abuts against the circuit board 12. Multiple heat dissipation holes 23 are formed on the lower surface of the lower shell 2, all of which connect to the placement cavity 21. When the circuit board 12 is located inside the placement cavity 21, the MOSFETs and chips in the circuit board 12 can abut against the thermal silicone 22, at which time the thermal silicone 22 can dissipate heat through the heat dissipation holes 23.
[0043] Reference Figure 2 and Figure 4 The fixed shell 5 has multiple guide grooves 51 and multiple through holes 53 connected to the guide grooves 51. The lower shell 2 has multiple mounting holes 24, and a plug 25 is fixedly connected to the surface of the lower shell 2 facing the fixed shell 5, with the mounting holes 24 extending through to the surface of the plug 25. The plug 25 can be inserted into the through holes 53 to achieve pre-fixation of the lower shell 2 and the fixed shell 5. The protective shell 4 has multiple guide blocks 41 fixedly connected, which can be inserted into the guide grooves 51, and the surface of the guide blocks 41 has mounting grooves 42.
[0044] Reference Figure 2 and Figure 4The lower shell 2 is provided with multiple mounting bolts 26. The mounting bolts 26 can pass through the mounting holes 24 and through holes 53 and be inserted into the mounting groove 42, and the mounting bolts 26 can be threaded into the mounting groove 42. When the guide block 41 is inserted into the guide groove 51, the through holes 53 are aligned with the mounting groove 42, and at this time the mounting bolts 26 can pass through the mounting holes 24 and through holes 53 and be threaded into the mounting groove 42.
[0045] Reference Figure 4 and Figure 5 The panel 3 has a slot 31 for inserting the protective shell 4. Multiple limiting strips 32 are fixedly connected to the wall of the slot 31, and limiting blocks 321 are fixedly connected to the surface of each limiting strip 32. Both the limiting strips 32 and the limiting blocks 321 have a certain degree of elastic deformation capability. The protective shell 4 has multiple limiting holes 43 for inserting the limiting strips 32. The walls of the limiting holes 43 have limiting grooves 431 for inserting the limiting blocks 321. When the limiting strip 32 is located within the limiting hole 43, the limiting block 321 can be located within the limiting groove 431, thus fixing the panel 3 and the protective shell 4.
[0046] Reference Figure 4 and Figure 5 The protective shell 4 protrudes away from the fixed shell 5, and the protrusion of the protective shell 4 can be located within the placement groove 31 of the panel 3. Four receiving strips 44 are integrally formed on the protective shell 4, and the four receiving strips 44 are arranged in a circumferential array along the protective shell 4. Four receiving grooves 33 are formed on the side of the panel 3, and the receiving grooves 33 are connected to the placement groove 31, and the receiving grooves 33 allow the receiving strips 44 to be inserted. When the protrusion in the protective shell 4 is located within the placement groove 31, the receiving strip 44 is located within the receiving groove 33, and the limiting block 321 can be located within the limiting groove 431.
[0047] The implementation principle of Example 1 is as follows: the operator installs the circuit board 12 on the fixed shell 5, inserts the guide block 41 into the guide groove 51, and then inserts the limiting block 321 into the limiting groove 431 to fix the panel 3, the protective shell 4 and the fixed shell 5 to each other. Finally, the heat dissipation silicone 22 is placed on the placement cavity 21, and the lower shell 2 and the upper shell 11 are assembled by the mounting bolts 26.
[0048] Example 2
[0049] Reference Figure 6 and Figure 7The difference between this embodiment and Embodiment 1 is that two fixing spring pieces 52 are fixedly connected to the fixing shell 5, and the fixing spring pieces 52 deform towards the other fixing spring piece 52. The protective shell 4 has two fixing holes 45 for the fixing spring pieces 52 to pass through. Grooves 46 are formed on the opposite sides of the protrusions in the protective shell 4, allowing the fixing spring pieces 52 to be inserted. When the fixing spring piece 52 passes through the fixing hole 45 and is inserted into the groove 46, the guide block 41 is located in the guide groove 51, thus achieving mutual fixation between the protective shell 4 and the fixing shell 5.
[0050] Reference Figure 6 and Figure 7 The panel 3 has two sliding grooves 34, which connect to the receiving groove 33 extending along the length of the protective shell 4. A stop block 341 is slidably connected within the sliding groove 34, and the stop block 341 can move from the receiving groove 33 into the sliding groove 34. A receiving inclined surface 441 is formed on the surface of the receiving strip 44 facing the stop block 341. The distance between the receiving inclined surface 441 and the fixed shell 5 gradually decreases from the receiving groove 33 along the length of the protective shell 4 to the sliding groove 34 on the same side, and the receiving inclined surface 441 is located on the moving path of the stop block 341.
[0051] Reference Figure 6 and Figure 7 When panel 3 is assembled on protective shell 4, and protective shell 4 is assembled on fixed shell 5, receiving strip 44 is located in receiving groove 33. At this time, receiving strip 44 drives stop block 341 to move to the side of fixed spring piece 52 away from bottom wall of groove 46 through receiving inclined surface 441, so as to limit the stop block 341 on fixed spring piece 52.
[0052] The implementation principle of Example 2 is as follows: First, the protective shell 4 is assembled on the fixed shell 5, and the fixing spring piece 52 passes through the fixing hole 45 and is located in the groove 46. Then, the panel 3 is assembled on the protective shell 4, and the receiving strip 44 drives the stop block 341 to move through the receiving inclined surface 441, so that the stop block 341 is located on the side of the fixing spring piece 52 away from the bottom wall of the groove 46, thereby limiting the fixing spring piece 52 by the stop block 341.
