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.

[0037] Name Explanation: In the connector field, "Housing" refers to the outer shell of the connector, usually made of plastic. Its main function is protection, housing and protecting the internal terminals and other components of the connector from external environmental influences, while ensuring the stability of the electrical connection.

[0038] Example 1

[0039] Please refer to Figures 1-3 One embodiment of this utility model provides a fixing structure and connection device for a RAST connector after wire crimping, including a Housing 1, a PCB board 2, and connection terminals 3:

[0040] The front of the Housing 1 is provided with a mounting slot 11, and the PCB board 2 is inserted into the mounting slot 11;

[0041] The mounting slot 11 has a plurality of insertion holes 12 arranged at equal intervals. The connecting terminal 3 is fixedly disposed in the insertion hole 12 and is connected to the PCB board 2.

[0042] The upper surface of the Housing 1 is provided with a wire hole 13 corresponding to the plug hole 12. The wire hole 13 is in communication with the plug hole 12. The wire harness 4 is inserted into the wire hole 13 and connected to the connection terminal 3.

[0043] A receiving groove 14 is provided at the center of the lower surface of the Housing 1. An elastic locking structure 5 is provided in the receiving groove 14. The elastic locking structure 5 is snapped together with the PCB board 2 so that the Housing 1 is fixedly connected to the PCB board 2.

[0044] Understandably, in this embodiment, by inserting the PCB board 2 into the mounting slot 11 on the front of the Housing 1, the PCB board 2 and the Housing 1 are initially mechanically connected. The insertion holes 12 arranged at equal intervals in the Housing 1 are fixed with connecting terminals 3, which are electrically connected to the PCB board 2 to establish a path for signal transmission. The wire harness 4 is inserted from the wire hole 13 on the upper surface of the Housing 1 corresponding to the insertion hole 12 and connected to the connecting terminal 3 to complete the electrical connection between the wire harness 4 and the PCB board 2. Finally, the elastic locking structure 5 in the receiving groove 14 on the lower surface of the Housing 1 is fastened to the PCB board 2 to achieve a firm fixation of the Housing 1 and the PCB board 2, ensuring the stability of the entire connector structure.

[0045] Among them, the connecting terminal 3 serves as a conductive medium, with one end in close contact with a specific pad or connection point on the PCB board 2 to form a low-resistance electrical path, and the other end connected to the wire in the wire harness 4, enabling the electrical signal to be transmitted efficiently and stably between the wire harness 4 and the PCB board.

[0046] The fixing structure of the RAST connector after wire crimping provided by this utility model can achieve the following technical effects:

[0047] 1. The design of the elastic locking structure 5 enables the Housing1 to be tightly fixed to the PCB board, effectively preventing the connector from loosening when the equipment is running or subjected to external interference, ensuring the reliability of the connection, and reducing the probability of connection instability caused by the connector being prone to loosening.

[0048] 2. The overall structure is simple and reasonable, with a relatively small number of parts. During assembly, simply insert the PCB board, connect the wire harness 4, and complete the snap-fit ​​fixation in sequence. The operation is simple and quick. At the same time, when maintenance or replacement of parts is required, it can be quickly disassembled and reassembled, reducing the difficulty and cost of maintenance.

[0049] Example 2

[0050] Please refer to Figure 3 In one embodiment of this utility model, the connecting terminal 3 has a three-section structure: front, middle and rear. The front section of the connecting terminal 3 is configured as a piercing structure 31, which is used to pierce the insulation sheath of the wire harness 4 so that the wire harness 4 is electrically connected to the connecting terminal 3. The rear section of the connecting terminal is configured as an elastic clip 32, which is used to fix the PCB board 2 and electrically connect to the contacts on the PCB board 2.

[0051] The middle section of the connecting terminal 3 is also provided with a backstop structure 33, and the Housing 1 is provided with a positioning groove corresponding to the backstop structure 33, so that when the connecting terminal 3 is inserted, the backstop structure 33 is engaged in the positioning groove.

[0052] The elastic locking structure 5 includes a locking body 51, a connector 52, and a guide 53. The locking body 51 is rotatably mounted in the receiving groove 14 through the connector 52. The two ends of the locking body 51 are respectively provided with a contact part and a locking part, and the guide 53 is provided on the locking part.

[0053] The PCB board 2 has an alignment notch on one side that is inserted into the mounting slot 11.

[0054] Understandably, in this embodiment, the front end of the connecting terminal 3 is set as a piercing structure 31. This design enables the connecting terminal 3 to firmly pierce and fix the wire harness 4, thereby achieving mechanical fixation and circuit connection. The rear end of the connecting terminal 3 is an elastic clip 32. When the PCB board 2 is inserted into the mounting slot 11, the elastic clip 32 will make close contact with the contacts on the PCB board 2, thereby achieving electrical connection and fixing the PCB board 2.

[0055] In addition, a retaining structure 33 is provided in the middle section of the connecting terminal 3. When the connecting terminal 3 is inserted into the insertion hole 12 of the Housing 1, the retaining structure 33 will be locked into the positioning groove on the Housing 1 to prevent the connecting terminal 3 from loosening or falling off due to vibration or other external forces during use.

[0056] In the elastic locking structure 5, the locking body 51 is rotatably installed in the receiving groove 14 via the connector 52. When the PCB board 2 is inserted into the mounting slot 11, the contact part of the locking body 51 first contacts the PCB board 2. As the PCB board 2 is further inserted, the locking body 51 rotates around the connector 52, and finally the engaging part is engaged with the PCB board 2. The guide 53 is provided on the engaging part, which helps to guide the locking body 51 to engage correctly with the PCB board 2 and ensure the stability of the connection.

[0057] Furthermore, the PCB board 2 has an alignment notch on one side that is inserted into the mounting slot 11. This alignment notch matches the structure on the Housing 1, ensuring that the PCB board 2 can be accurately inserted into the designated position, preventing reverse insertion or incorrect insertion, and improving the accuracy and efficiency of assembly.

[0058] The fixing structure of the RAST connector after wire crimping provided by this utility model can achieve the following technical effects:

[0059] 1. The three-section structure design of the connecting terminal 3 includes the piercing structure 31 and the elastic clip 32, which ensure the stable connection between the wire harness 4 and the PCB board 2 from both mechanical and electrical aspects.

[0060] 2. The cooperation between the anti-retraction structure 33 and the positioning groove further enhances the fixation of the connecting terminal 3 within the Housing 1, effectively preventing loosening or falling off, and the precise alignment of the alignment notch makes the fixation between the Housing 1 and the PCB board 2 more secure, reducing connection instability caused by external forces or vibrations.

[0061] Example 3

[0062] Please refer to Figures 1-5 In one embodiment of this utility model, the connector 52 is a rotating shaft. The connector 52 is disposed at the center of the latch body 51 and connected to the side wall of the receiving groove 14 so that the force arm formed by the contact part and the engaging part is the same.

[0063] An elastic element is provided between the contact portions, and the elastic element is used to keep the guide 53 in an engaged state with the PCB board 2.

[0064] Understandably, when the PCB board 2 is inserted, the engaging part is pressed, and the locking body 51 rotates around the rotating axis. After installation, the engaging part is stably engaged on the PCB board 2 to ensure a stable connection. At the same time, an elastic element is provided between the contact part receiving grooves 14 to keep the guide 53 in the engaging state with the PCB board 2. The elastic element provides elastic force to counteract the influence of external force or vibration and maintain stable engagement.

[0065] The fixing structure of the RAST connector after wire crimping provided by this utility model can achieve the following technical effects:

[0066] 1. The installation position design of the rotating shaft and the combined effect of the elastic force of the elastic element make the locking body 51 and the PCB board 2 more secure, effectively preventing the connection from loosening due to external force or vibration, and improving the reliability of the connection; when maintenance is required, the locking can be released by overcoming the elastic force of the elastic element, and the PCB board 2 can be quickly disassembled, improving maintenance efficiency.

[0067] Example 4

[0068] Please refer to Figures 1-4 , Figures 6-7 In one embodiment of this utility model, the connector 52 consists of two spaced elastic support piles connected to the bottom of the receiving groove 14, so that the guide 53 is kept in an engaged state with the PCB board 2.

[0069] A limiting block is also provided at the opening of the receiving groove 14 to limit the contact part.

[0070] Understandably, the connector 52 uses two spaced-apart elastic support posts installed at the bottom of the receiving groove 14. When the PCB board 2 is inserted into the mounting slot 11, the engaging part of the latching body 51 contacts the PCB board 2, and the elastic support posts undergo elastic deformation, generating elastic support force. This allows the guide 53 of the latching body 51 to fit tightly against the PCB board 2, maintaining the engaging state and ensuring the stability of the connection. A limiting block is also included to restrict the range of motion of the contact part of the latching body 51. When the latching body 51 rotates around the elastic support posts, the limiting block prevents excessive movement of the contact part, preventing the latching body 51 from coming out of the receiving groove 14. Simultaneously, it ensures that the contact force between the latching body 51 and the PCB board 2 is moderate, avoiding damage or poor contact due to excessive compression.

[0071] The fixing structure of the RAST connector after wire crimping provided by this utility model can achieve the following technical effects:

[0072] 1. The elastic support force of the elastic support pile ensures that the locking body 51 and the PCB board 2 are tightly fitted. Even under vibration or external force, it can maintain a stable locking state, effectively preventing the connection from loosening or falling off, and improving the reliability of the connection.

[0073] Example 5

[0074] One embodiment of this utility model also discloses a connection device, including a fixing structure after the RAST connector wire is crimped as described in any of the above embodiments.

[0075] The connection device provided by this utility model can achieve the following technical effects:

[0076] 1. The design of the elastic locking structure 5 enables the Housing1 to be tightly fixed to the PCB board, effectively preventing the connector from loosening when the equipment is running or subjected to external interference, ensuring the reliability of the connection, and reducing the probability of connection instability caused by the connector being prone to loosening.

[0077] 2. The overall structure is simple and reasonable, with a relatively small number of parts. During assembly, simply insert the PCB board, connect the wire harness 4, and complete the snap-fit ​​fixation in sequence. The operation is simple and quick. At the same time, when maintenance or replacement of parts is required, it can be quickly disassembled and reassembled, reducing the difficulty and cost of maintenance.
