Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a connector structure. Background Technology

[0002] Connectors are widely used in computers, mobile phones, home appliances, automobiles, and other fields, and are one of the key components for signal transmission between electronic devices. As electronic products develop towards miniaturization and lightweighting, connector design faces higher requirements.

[0003] In connector design, it is often necessary to set resistors inside the connector for thermal protection and impedance matching. Resistors are usually mounted on the PCB board in the form of surface mount, which often occupies a lot of space, affecting the spatial distribution of the entire connector and resulting in low utilization of the internal space of the connector. Utility Model Content

[0004] The purpose of this application is to overcome the above-mentioned technical problems and provide a connector structure.

[0005] A connector structure, comprising:

[0006] A terminal assembly includes a detachably connected upper terminal plate and a lower terminal plate, wherein terminal blocks are fixed on the same side of the upper terminal plate and the lower terminal plate, and the two terminal blocks are spaced apart. The lower terminal plate includes a bearing surface and a protrusion protruding from the bearing surface.

[0007] A shielding sheet is disposed on the bearing surface and sandwiched between the upper terminal plate and the lower terminal plate. Both the shielding sheet and the upper terminal plate expose the protrusion. The protrusion is provided with a resistor electrically connected to the terminal block included in the lower terminal plate.

[0008] The housing is fitted with the terminal assembly, and the end of the housing has a terminal hole, each terminal hole corresponding to a terminal block including one terminal.

[0009] By adopting the above solution, the resistor is placed on the protruding part and soldered at this part, saving internal space of the connector.

[0010] In one embodiment, two opposing surfaces of the shielding sheet are respectively provided with spring contacts, which are electrically connected to the terminal block.

[0011] By adopting the above solution, the shielding sheet is connected to the terminal block via a spring contact to achieve ground connection.

[0012] In one embodiment, the upper terminal plate has wings extending along the length direction on opposite sides, the terminal group is located between the two wings, the wings are embedded with U-shaped buckles, the housing has a guide groove, and the buckle portion is located in the guide groove and protrudes out of the housing.

[0013] By adopting the above solution, a snap-fit ​​mechanism is installed on the connector to make the connection more stable.

[0014] In one embodiment, the housing includes an inner shell and an outer shell. The inner shell has the terminal hole and the guide groove. The outer shell is fitted onto the inner shell. The end of the buckle away from the wing is provided with a hook and a supporting arm located on the same side as the buckle. The supporting arm and the hook are both located outside the outer shell.

[0015] By using the above method, the buckle can be pressed vertically into the inner shell by pressing the holding arm.

[0016] In one embodiment, the connector structure further includes a connector located at one end of the terminal assembly, the connector being capable of fixing the upper terminal plate and the lower terminal plate.

[0017] By adopting the above solution, the upper terminal plate and the lower terminal plate are fixed together.

[0018] In one embodiment, the connector further includes a rear housing that is fitted onto the connector and fixed to the terminal assembly.

[0019] The terminal assembly is protected by adopting the above solution.

[0020] In one embodiment, the surfaces of the upper terminal plate and the lower terminal plate opposite to each other are provided with clearance holes, and the resistor is located in the clearance holes.

[0021] By adopting the above solution, the resistor is exposed on the surface of the terminal assembly, saving internal space of the terminal assembly. The clearance hole serves to avoid contact with the resistor, preventing accidental contact.

[0022] In one embodiment, the terminal block of the lower terminal plate includes a protruding end that is electrically connected to the resistor.

[0023] By adopting the above scheme, the terminal blocks in the upper terminal board and the lower terminal board can be connected by resistance.

[0024] In one embodiment, the protrusion extends toward the clearance hole and its surface is flush with the bottom surface of the resistor.

[0025] By adopting the above solution, the protruding part supports the resistor and prevents displacement between the resistor and the terminal block, which could lead to poor contact.

[0026] In one embodiment, the protrusion extends along the direction of the protruding end to fix the protruding end, and the contact surface between the protruding end and the resistor exposes the protrusion.

[0027] By adopting the above solution, the protruding part fixes the protruding end, preventing deformation of the protruding end that could lead to poor contact with the resistor.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By using the protruding ends to overlap the terminal blocks, a solder pad is formed between the upper and lower terminal blocks. The resistor is soldered to this part, thus eliminating the need to connect the resistor through the PCB board and improving the internal space layout of the connector.

[0030] 2. By setting clearance holes on the upper terminal block, the resistor is placed inside the clearance holes, exposing the resistor to the surface of the terminal assembly. The clearance holes serve to avoid contact with the resistor, preventing accidental contact, and also saving internal space of the terminal assembly.

[0031] 3. By setting "U"-shaped buckles on both sides of the upper terminal block, the buckles can deform to fix the connector in the socket, making the connection of the connector more stable and reliable and preventing the connector from loosening in the socket. Attached Figure Description

[0038] Therefore, it is necessary to provide a connector structure with high internal space utilization.

[0039] Please see Figure 1-2 , Figure 1 A schematic diagram of a connector structure provided in this application includes: a terminal assembly 1, a shielding sheet 2, and a housing 3.

[0040] Please also refer to Figure 3 , Figure 3 This is a schematic diagram of the terminal assembly 1. The terminal assembly 1 includes an upper terminal plate 11 and a lower terminal plate 12. A connector 6 is sleeved on one end of the terminal assembly 1, fixing the upper terminal plate 11 and the lower terminal plate 12, thus achieving a detachable connection between the upper terminal plate 11 and the lower terminal plate 12. A rear shell 7 is also sleeved on the surface of the connector 6. The rear shell 7 can be made of plastic to improve the mechanical strength and reliability of the connector. The rear shell 7 is snapped and fixed to the terminal assembly 1, making the connection between the terminal assembly 1 and the connector 6 tighter.

[0041] Please also refer to Figure 4 , Figure 4 This diagram illustrates the connection between terminal block 13 and shielding plate 2. The upper terminal plate 11 and lower terminal plate 12 are integrally injection molded to fix terminal block 13 inside. Terminal block 13 extends a lead as a protruding end 131, which overlaps with the opposite terminal block 13, forming a solder pad. Resistor 5 is soldered to this solder pad, connecting protruding end 131 to the terminal block 13 on the other side. This design allows resistor 5 to be directly soldered to the overlapping part 122 without requiring an additional PCB board, thus saving internal space in the connector structure.

[0042] The lower terminal plate 12 is provided with a bearing surface 121 and a protrusion 122. The bearing surface 121 is located below the edge of the lower terminal plate 12, forming a groove structure with the edge of the lower terminal plate 12. The protrusion 122 protrudes from the bearing surface 121. The shielding sheet 2 is placed on the bearing surface 121 and sandwiched between the upper terminal plate 11 and the lower terminal plate 12, providing good electromagnetic shielding and preventing external electromagnetic interference from affecting the normal operation of the connector. Two opposing surfaces of the shielding sheet 2 are provided with spring contacts 21. The spring contacts 21 and the upper terminal plate 11 are both exposed in the protrusion 122. The spring contacts 21 abut against the terminal block 13 for electrical connection, realizing the connection between the shielding sheet 2 and ground. The shielding sheet 2 can be made of metal foil or other conductive materials to shield electromagnetic interference and improve the electromagnetic compatibility of the connector. The shielding sheet 2 can be connected to the terminal block 13 by welding, bonding, or crimping to ensure good electrical connection.

[0043] In this application, the upper terminal block 11 has a clearance hole 112 on its surface, and the resistor 5 is located within the clearance hole 112. The clearance hole 112 is designed so that the resistor 5 can be exposed on the surface of the terminal assembly 1, avoiding occupying internal space. The shape and size of the clearance hole 112 can be adjusted according to the size of the resistor 5 to ensure that the resistor 5 can be smoothly inserted into the clearance hole 112. The clearance hole 112 is chamfered to prevent finger scratches and accidental finger contact with the resistor 5. The protrusion 122 extends along the protrusion 131 toward the clearance hole 112. The surface of the protrusion 122 is flush with the bottom surface of the resistor 5, providing support for the resistor 5 and preventing displacement between the resistor 5 and the upper and lower terminal blocks 13, which could lead to poor contact. The contact surface between the protrusion 131 and the resistor 5 is exposed in the protrusion. The protrusion 122 positions the protrusion 131, effectively preventing deformation of the protrusion 131 and ensuring a stable connection between the protrusion 131 and the resistor 5. The length and width of the protruding part 122 can be adjusted according to actual needs.

[0044] Please also refer to Figure 5 , Figure 5This diagram illustrates the connection between the inner shell 31 and the latch 4. The upper and lower terminal plates 12 have wings 111 extending along their length on opposite sides. The terminal assembly is located between the two wings 111. A U-shaped latch 4 is embedded within each wing 111. The shell 3 includes an inner shell 31 and an outer shell 32. The outer shell 32 is made of metal and provides stable protection for the terminal assembly 1. The inner shell 31 is made of rubber and possesses good elasticity and insulation. The outer shell 32 is fitted onto the inner shell 31. The latch 4 has a hook 41 and a supporting arm 42 on the same side as the hook 41 at the end furthest from the wing 111. The inner shell 31 has terminal holes 311 and guide grooves 312. Each terminal hole 311 on the inner shell 31 corresponds one-to-one with a terminal in the terminal block 13. The size and shape of the terminal holes 311 can be adjusted according to the size and shape of the terminals to ensure smooth insertion and removal of the terminals.

[0045] Both the holding arm 42 and the hook 41 of the buckle 4 are located outside the housing 32. By pressing the holding arm 42, the buckle 4 can be pressed vertically into the guide groove 312. The size and shape of the guide groove 312 can be adjusted according to the size and shape of the buckle 4 to ensure that the buckle 4 can smoothly enter the guide groove 312. The hook 41 of the buckle 4 can adapt to sockets or other connectors of different specifications.

[0046] When in use, when the connector needs to be plugged into a socket or other connectors, first press the holding arm 42 of the buckle 4 so that the hook 41 is embedded in the guide groove 312. After inserting the connector into the socket, release the holding arm 42 so that the hook 41 of the buckle 4 engages with the socket, making the connector more stable and reliable during insertion and removal, and preventing the connector from loosening in the socket.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
