[0034] Example 1:

[0035] like Figures 1-2 As shown, this embodiment provides a single-hole sintered connector, which includes:

[0036] The shell 1 is a hollow cylindrical structure and can be made of insulating materials such as plastic;

[0037] The connecting seat 2 is sleeved with the housing 1, and the housing 1 and the connecting seat 2 are coaxially arranged. At the same time, the connecting seat 2 has several axial through holes 21 in the axial direction; preferably, the housing 1 and the connecting seat 2 are detachably connected.

[0038] A plurality of pins 3, and each pin 3 is inserted into an axial through hole 2, further, the pin 2 can be prepared by milling, drilling and other processes of conductive materials such as copper bar, and can be inserted into other electrical equipment to realize electrical connection, and the number of pins 3 is greater than or equal to 10;

[0039] The filler is filled in the gap between the pin 3 and the axial through hole 21, and in this embodiment, the filler is an insulating material such as glass, which can be obtained by injecting liquid glass into the gap between the pin 3 and the axial through hole 2, and cooling and sintering;

[0040] The burning control unit 4 is detachably connected to the connecting seat 2 and accommodated in the shell 1;

[0041] The foolproof structure 5 is connected to the shell 1 and the burning control unit 4, and is designed as an asymmetric structure, so that the uniqueness of the connector during installation and use can be ensured by the foolproof structure 5 to prevent installation and use errors;

[0042] And at least one functional module, in this embodiment, the functional module is at least 2, and the functional module can be set according to actual needs, such as completing electrical signal transmission control, electrical signal processing and the like;

[0043] At the same time, the burning control unit 4 is connected to the corresponding pin 3 and the functional module through the welding wire and the like, for completing the program burning of the corresponding functional module, and in this embodiment, the burning control unit 4 and the functional module can be integrated on the assembly structure such as the PCB assembly.

[0044] The connector in this embodiment is provided with a plurality of pins 3 as pins, when burning and communication updating are needed, the positive, negative and communication leads of the burning control unit 4 are respectively electrically connected to the corresponding pin 3 through the welding wire, and the program burning can be completed through the burning emulator and the like,

[0045] For example, as shown in the figure, Figures 5-6 When the functional module includes functional module one 100 and functional module two 101, if the pin 3 numbered 1, 2 and 3 and the functional module one 100 are connected to the burning control unit 4, the program burning of the functional module one 100 can be completed, and if the pin 3 numbered 14, 15 and 16 and the functional module two 101 are connected to the burning control unit 4, the program burning of the functional module two 101 can be completed.

[0046] Thus, in the embodiment, the corresponding pins 3, function modules and burning control units 4 can be connected according to actual scene use requirements, that is, the requirements of different program burning can be met, so as to greatly expand the application range. At the same time, only the assembly gap between each pin and the axial through hole is fixed by glass sintering, and glass sintering is not required at other positions, so as to reduce the cost by single-hole sintering.

[0047] Further, as shown in Figure 3 , a stepped portion 111 extending towards the inside of the axial through hole 21 is formed on the inner wall surface of each axial through hole 21, and the outer wall surface of each pin 3 is formed as an extension portion 31. When the pin 3 is inserted and matched with the axial through hole 21, the stepped portion 111 and the extension portion 31 abut each other to realize the axial positioning of the pin 3 and prevent the pin position from deviating.

[0052] Embodiment 2:

[0053] The difference between the embodiment and the embodiment 1 is that, as shown in Figures 4-5 , the outer wall surface of the connecting seat 22 is provided with a mounting groove 222 for accommodating an O-shaped sealing ring 7. Thus, after the connecting seat 22 and the shell 1 are sleeved and matched, sealing can be realized by the O-shaped sealing ring 7 to achieve good waterproof and dustproof effects.

[0054] In addition, in order to enhance the connection and fixing effect, as shown in Figure 1 , the outer wall surface of the shell 1 is provided with a clamping groove 12; correspondingly, as shown in Figure 4As shown, the outer peripheral surface of the cover 1 is connected with a clamping block 211 connected with the clamping groove 12, in the embodiment, the clamping block 211 and the cover 1 can be integrally formed, and the clamping groove 12 and the clamping block 211 can be multiple, thus, when the adapter seat 22 and the shell 1 are sleeved and matched, the clamping groove 12 and the clamping block 211 are matched with each other to strengthen the fixing effect.

[0057] As can be seen from the above, the connector in the utility model is provided with multiple pins, when burning and communication updating are needed, the burning control unit is electrically connected with the corresponding pin and the functional module through soldering, and the program burning can be completed through a module such as a burning emulator, thereby meeting the program burning demand of different functional modules to greatly expand the application range, and only the assembly gap between each pin and the axial through hole is fixed through glass sintering, and other positions do not need to be sintered through glass, so that the cost is reduced through single-hole sintering.

[0058] In addition, the connector further enhances the connection strength through fastening structures such as clamping grooves, clamping blocks and mounting holes, and increases the sealing effect through a sealing ring, and the foolproof structure can ensure the uniqueness of the connector in the process of component installation and use to prevent installation and use errors.
