Technical Field

[0001] This utility model relates to the field of electrical connector technology, specifically to a CAN bus connector that prevents mis-mating. Background Technology

[0002] With its high reliability, strong real-time performance, and excellent anti-interference capabilities, the CAN bus has been widely used in many fields such as automotive electronics, industrial automation, aerospace, and intelligent transportation. Taking automotive electronics as an example, a large number of electronic devices in a vehicle, such as the engine control unit, transmission controller, airbag system, and in-vehicle entertainment system, rely on the CAN bus to achieve communication and collaborative operation.

[0003] For example, Chinese Patent Publication No. CN206364329U discloses an anti-misinsertion interlocking rectangular connector, relating to the field of electrical connector technology. It includes a rectangular plug and a rectangular socket, wherein: a rotating screw is provided on one side of the rectangular plug, and a rotating long nut is provided on the other side; a fixed long nut is provided on one side of the rectangular socket, and a fixed screw is provided on the other side; during insertion, the rotating screw and the fixed long nut interlock, and the rotating long nut and the fixed screw interlock. This utility model designs a rotating screw on one side of the rectangular plug and a rotating long nut on the other side; correspondingly, a fixed long nut is provided on one side of the rectangular socket, and a fixed screw is provided on the other side. Thus, during the insertion of the rectangular plug into the rectangular socket, it can only be inserted when the rotating screw corresponds to the fixed long nut and the fixed screw corresponds to the rotating long nut, effectively preventing misinsertion, protecting the plug pins, and thus ensuring the accuracy of data transmission.

[0004] Currently, there are still some shortcomings in the anti-misfit interlocking rectangular connector. For example, when it is necessary to replace the connector and the connecting wire, a special connector needs to be customized to match the use, which increases maintenance costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a CAN bus connector that prevents mis-insertion, thus solving the problems mentioned in the background art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A CAN bus connector designed to prevent mis-insertion includes: a bus connector, wherein a plurality of connectors are provided on one side of the bus connector, a connector head is movably snapped onto one side of the connector head, an upper outer shell and a lower outer shell are provided on the outside of the connector head, a shaped block is fixedly installed on one side of the upper outer shell, and a shaped groove is provided on one side of the connectors; and a connecting assembly, wherein the connecting assembly is provided on both sides of the upper outer shell for connecting the upper outer shell and the connector head.

[0008] Preferably, the connecting assembly includes: a plurality of connecting blocks, the plurality of connecting blocks being fixedly installed on both sides of the upper outer shell and the lower outer shell respectively, the top surface of the connecting blocks having connecting holes, a connecting rod being movably fitted inside every two connecting holes, and limit blocks being fixedly installed at both ends of the connecting rod, with a spring provided between the limit blocks and the connecting blocks.

[0009] Preferably, a rubber pad is fixedly adhered to one side of the inner surface of the upper outer shell and the lower outer shell.

[0010] Preferably, a transparent shell is fixedly installed on the top surface of the upper outer shell, a color card is placed inside the transparent shell, and color matching paper is fixedly adhered to the top surface of the connecting joint.

[0011] Preferably, two magnetic blocks are provided on one side of both the upper and lower outer shells, and several magnetic holes are opened on one side of the connecting joint, so that the magnetic blocks are attracted to the magnetic holes.

[0012] Preferably, a number of indicator lights are provided on one side of the bus connector.

[0013] In summary, the present invention has the following main advantages:

[0014] By incorporating connecting blocks, when a connector needs replacement, workers can pull the upper and lower outer shells up and down. This compresses the springs, causing the upper and lower outer shells to expand upwards and downwards respectively, allowing them to be removed from the damaged connector. The new connector can then be fitted onto it. Loosening the upper and lower outer shells causes the springs to close them, securing them to the new connector. Rubber pads prevent over-tightening, which could damage the connector's outer shell and cause deformation. This avoids the need for custom-made connectors and reduces maintenance costs.

[0015] By setting up magnetic blocks, when the operator brings the connector close to the connector, the magnetic blocks will automatically attract to the magnetic holes, generating a certain pulling force to guide the connector to quickly and accurately align with the connector and complete the initial connection. This eliminates the need for manual fine-tuning by the operator, effectively saving connection time. At the same time, it can resist a certain degree of external force pulling, vibration and other interference, preventing the connector from accidentally loosening or falling off.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] refer to Figures 1-4 A CAN bus connector designed to prevent mis-insertion includes: a bus connector 1, with a plurality of connectors 2 on one side of the bus connector 1, a connector 3 movably latched onto one side of the connectors 2, an upper outer shell 5 and a lower outer shell 6 on the outside of the connector 3, a shaped block 7 fixedly installed on one side of the upper outer shell 5, and a shaped groove 8 opened on one side of the connectors 2; and a connection assembly, which is disposed on both sides of the upper outer shell 5 and is used to connect the upper outer shell 5 to the connector 3.

[0023] By setting the irregular block 7, when the operator connects the connector 3 to the connector 2, the irregular block 7 can only be inserted into the corresponding irregular slot 8 and cannot be inserted into other irregular slots 8. This prevents the operator from accidentally inserting the connector and avoids damage to the bus connector 1, which would affect the service life of the bus connector 1.

[0024] As a further embodiment of this utility model, the connecting assembly includes: a plurality of connecting blocks 9, which are respectively fixedly installed on both sides of the upper outer shell 5 and the lower outer shell 6. The top surface of the connecting block 9 is provided with a connecting hole 10, and a connecting rod 11 is movably sleeved inside every two connecting holes 10. Both ends of the connecting rod 11 are fixedly installed with limit blocks 12, and a spring 13 is provided between the limit block 12 and the connecting block 9.

[0025] By setting the connecting block 9, when the connector 3 needs to be replaced, the operator can pull the upper outer shell 5 and the lower outer shell 6 up and down. At this time, the spring 13 is in a compressed state, and the upper outer shell 5 and the lower outer shell 6 expand upward and downward respectively, so that they can be removed from the damaged connector 3. Then, they can be put into the new connector 3. When the upper outer shell 5 and the lower outer shell 6 are released, the spring 13 drives the upper outer shell 5 and the lower outer shell 6 to close and assemble, and fix them on the new connector 3. This avoids the need to customize special connectors 3 and reduces maintenance costs.

[0026] As a further embodiment of this utility model, a rubber pad 14 is fixedly adhered to one side of the inner surface of the upper outer shell 5 and the lower outer shell 6.

[0027] By setting the rubber pad 14, when the upper outer shell 5 and the lower outer shell 6 are assembled on the connector 3, the rubber pad 14 prevents over-tightening, which could damage the outer shell of the connector 3, causing deformation of the outer shell of the connector 3 and affecting its use.

[0028] As a further embodiment of this utility model, a transparent shell 15 is fixedly installed on the top surface of the upper outer shell 5, a color card is placed inside the transparent shell 15, and a color matching paper 16 is fixedly adhered to the top surface of the connecting connector 2.

[0029] By setting a transparent shell 15, when the operator inserts the connector 3 into the connector 2, they can compare the color card with the color matching paper 16 in the connector 2, which makes it convenient for the operator to quickly insert the connector 3.

[0030] As a further embodiment of this utility model, two magnetic blocks 17 are provided on one side of the upper outer shell 5 and the lower outer shell 6, and several magnetic holes 18 are opened on one side of the connecting joint 2, and the magnetic blocks 17 are attracted to the magnetic holes 18.

[0031] By setting up the magnetic block 17, when the staff brings the connector 3 close to the connector 2, the magnetic block 17 will automatically be attracted to the magnetic hole 18, generating a certain pulling force to guide the connector 3 to quickly and accurately align with the connector 2 and complete the initial connection. There is no need for the staff to manually make fine position adjustments, which effectively saves connection time. At the same time, it can resist a certain degree of external force pulling, vibration and other interference, and prevent the connector 3 from accidentally loosening or falling off.

[0032] As a further embodiment of this utility model, a number of indicator lights 4 are provided on one side of the bus connector 1;

[0033] By setting indicator light 4, when connector 3 is correctly inserted into connector 2 and the entire CAN bus system is connected normally and data transmission is smooth, indicator light 4 can light up a stable green light. Staff can confirm at a glance that the connection is correct without having to troubleshoot using complex testing equipment or professional software. Conversely, if there is a problem with the connection, such as poor contact or incorrect insertion, indicator light 4 may light up red or flash to warn staff of abnormal conditions, enabling them to quickly detect the abnormality, improve work efficiency, and reduce the workload of technicians.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
