[0039] Embodiment 1

[0040] Please refer to Figures 1 - 3 , one embodiment of the present invention provides a fixing structure and a connection device after wire pressing for a RAST connector, including a Housing 1, a PCB board 2, and a connection terminal 3:

[0041] An installation slot 11 is provided on the front surface of the Housing 1, and the PCB board 2 is inserted into the installation slot 11;

[0042] A plurality of insertion holes 12 are equidistantly arranged in the installation slot 11, the connection terminal 3 is fixedly arranged in the insertion holes 12, and the connection terminal 3 is connected to the PCB board 2;

[0043] A wire passing hole 13 corresponding to the insertion holes 12 is provided on the upper surface of the Housing 1, the wire passing hole 13 communicates with the insertion holes 12, the wire harness 4 is inserted into the wire passing hole 13, and is connected to the connection terminal 3;

[0044] A receiving groove 14 is provided at the center of the lower surface of the Housing 1, an elastic locking structure 5 is arranged in the receiving groove 14, and the elastic locking structure 5 is snap - connected to the PCB board 2 to fixedly connect the Housing 1 and the PCB board 2;

[0045] Wherein, the PCB board 2 is provided with connection contacts for electrically connecting to the connection terminal 3.

[0046] Understandably, in this embodiment, the PCB board 2 is inserted into the installation slot 11 on the front side of the Housing 1, enabling a preliminary mechanical connection between the PCB board 2 and the Housing 1. Connection terminals 3 are fixed in the equally spaced insertion holes 12 within the Housing 1. These connection terminals 3 are electrically connected to the PCB board 2, establishing a path for signal transmission. The wire harness 4 is inserted through the wire passing holes 13 corresponding to the insertion holes 12 on the upper surface of the Housing 1 and connected to the connection terminals 3, completing the electrical connection between the wire harness 4 and the PCB board 2. Finally, relying on the snap connection between the elastic locking structure 5 within the accommodation groove 14 on the lower surface of the Housing 1 and the PCB board 2, the firm fixation of the Housing 1 and the PCB board 2 is achieved, ensuring the stability of the entire connector structure.

[0047] Among them, as a conductive medium, one end of the connection terminal 3 is in close contact with specific pads or connection points on the PCB board 2, forming a low-resistance electrical path, and the other end is connected to the wires in the wire harness 4, enabling efficient and stable transmission of electrical signals between the wire harness 4 and the PCB board.

[0048] The fixed structure of the RAST connector provided by the present invention after wire pressing can achieve the following technical effects:

[0049] 1. The design of the elastic locking structure 5 enables the Housing 1 and the PCB board to be firmly fixed, effectively preventing the connector from loosening during equipment operation or under external interference, ensuring the reliability of the connection, and reducing the probability of unstable connection caused by the easy loosening of the connector.

[0050] 2. The overall structure design is simple and reasonable, and the number of components is relatively small. During assembly, it is only necessary to insert the PCB board, connect the wire harness 4, and complete the snap fixation in sequence, with simple and fast operation. At the same time, when maintenance or component replacement is required, it can also be quickly disassembled and reassembled, reducing the maintenance difficulty and cost.

[0051] Embodiment 2

[0052] Please refer to Figure 3 , in one embodiment of the present invention, the connection terminal 3 has a three-section structure of front, middle, and rear. The front section structure of the connection terminal 3 is set as a piercing structure 31 for piercing the insulation jacket of the wire harness 4 to electrically connect the wire harness 4 to the connection terminal 3. The rear section structure of the connection terminal is set as an elastic clip 32 for fixing the PCB board 2 and electrically connecting with the contacts on the PCB board 2.

[0053] The middle section structure of the connection terminal 3 is further 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 connection terminal 3 is inserted, the backstop structure 33 is snapped into the positioning groove.

[0054] The elastic locking structure 5 includes a locking body 51, a connecting member 52, and a guiding member 53. The locking body 51 is rotatably mounted in the accommodating groove 14 through the connecting member 52. Contact portions and engaging portions are respectively provided at two ends of the locking body 51, and the guiding member 53 is disposed on the engaging portion.

[0055] The PCB board 2 is provided with a alignment notch on one side when inserted into the installation slot 11.

[0056] It can be understood that in this embodiment, the front section of the connection terminal 3 is provided with a piercing structure 31. This design enables the connection terminal 3 to firmly pierce and fix the wire harness 4, achieving mechanical fixation and electrical connection; the rear section of the connection terminal 3 is an elastic clip 32. When the PCB board 2 is inserted into the installation slot 11, the elastic clip 32 will be in close contact with the contacts on the PCB board 2, thereby achieving electrical connection and fixing the PCB board 2;

[0057] In addition, a anti-retreat structure 33 is provided in the middle section of the connection terminal 3. When the connection terminal 3 is inserted into the insertion hole 12 of the Housing 1, the anti-retreat structure 33 will snap into the positioning groove on the Housing 1, preventing the connection terminal 3 from loosening or falling off due to vibration or other external forces during use;

[0058] In the elastic locking structure 5, the locking body 51 is rotatably mounted in the accommodating groove 14 through the connecting member 52. When the PCB board 2 is inserted into the installation slot 11, the contact portion 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 connecting member 52, and finally the engaging portion is snap-connected to the PCB board 2. The guiding member 53 is disposed on the engaging portion, which helps to guide the correct engagement of the locking body 51 and the PCB board 2, ensuring the stability of the connection;

[0059] Moreover, the PCB board 2 is provided with an alignment notch on one side when inserted into the installation 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 incorrect insertion or misalignment, and improving the accuracy and efficiency of assembly.

[0060] The fixed structure of the RAST connector after wire pressing provided by the present invention can achieve the following technical effects:

[0061] 1. In the three-section structure design of the connection terminal 3, the piercing structure 31 and the elastic clip 32 designs respectively ensure the stable connection between the wire harness 4 and the PCB board 2 from both mechanical and electrical aspects;

[0062] 2. The cooperation between the anti-retreat structure 33 and the positioning groove further enhances the fixation of the connection terminal 3 in the Housing 1, effectively preventing loosening or detachment, and the precise alignment of the alignment notch makes the fixation between the Housing 1 and the PCB board 2 more firm, reducing the problem of unstable connection caused by external force or vibration.

[0063] Embodiment 3

[0064] Please refer to Figures 1 - 5 , in one embodiment of the present invention, the connecting member 52 is a rotating shaft, the connecting member 52 is arranged at the center of the latch body 51, and is connected to the side wall of the accommodating groove 14, so that the force arms formed by the contact portion and the engaging portion are the same.

[0065] An elastic member is arranged between the contact portions, and the elastic member is used to keep the guiding member 53 in a clamped state with the PCB board 2.

[0066] It can be understood that when the PCB board 2 is inserted, the engaging portion is pressed, the latch body 51 rotates around the rotating shaft, and after being installed in place, the engaging portion is stably clamped on the PCB board 2 to ensure stable connection. At the same time, an elastic member is arranged between the contact portion and the accommodating groove 14 to keep the guiding member 53 in a clamped state with the PCB board 2. The elastic member provides an elastic force to offset the influence of external force or vibration and maintain the clamped state stably;

[0067] The fixed structure of the RAST connector provided by the present invention after wire pressing can achieve the following technical effects:

[0068] 1. The combined action of the installation position design of the rotating shaft and the elastic force of the elastic member makes the clamping between the latch body 51 and the PCB board 2 more firm, effectively preventing connection loosening caused by external force or vibration and improving the connection reliability; when maintenance is required, the clamping can be released by overcoming the elastic force of the elastic member, and the PCB board 2 can be quickly disassembled, improving the maintenance efficiency.

[0069] Embodiment 4

[0070] Please refer to Figures 1 - 4 , Figures 6 - 7 , in one embodiment of the present invention, the connecting member 52 is two elastic support piles arranged at intervals, and is connected to the bottom of the accommodating groove 14 to keep the guiding member 53 in a clamped state with the PCB board 2.

[0071] A limiting block is further arranged at the opening of the accommodating groove 14 for limiting the contact portion.

[0072] Understandably, the connecting member 52 adopts two elastically supporting piles arranged at intervals and is installed at the bottom of the accommodating groove 14. When the PCB board 2 is inserted into the installation slot 11, the engaging portion of the locking body 51 contacts the PCB board 2, and the elastically supporting piles undergo elastic deformation to generate an elastic supporting force, enabling the guiding member 53 of the locking body 51 to closely fit the PCB board 2, maintaining the engaging state, and ensuring the stability of the connection; and a limiting block is used to limit the movement range of the contact portion of the locking body 51. When the locking body 51 rotates around the elastically supporting pile, the limiting block prevents the contact portion from moving excessively, preventing the locking body 51 from disengaging from the accommodating groove 14, and at the same time ensuring that the contact force between the locking body 51 and the PCB board 2 is appropriate, avoiding damage or poor contact caused by excessive extrusion.

[0073] The fixed structure after wire pressing of the RAST connector provided by the present invention can achieve the following technical effects:

[0074] 1. The elastic supporting force of the elastically supporting piles ensures that the locking body 51 is closely attached to the PCB board 2. Even under vibration or external force, it can maintain a stable engaging state, effectively preventing the connection from loosening or falling off, and improving the reliability of the connection.

[0075] Embodiment 5

[0076] In one embodiment of the present invention, a connecting device is further pointed out, including the fixed structure after wire pressing of the RAST connector as described in any one of the above-mentioned multiple embodiments.

[0077] The connecting device provided by the present invention can achieve the following technical effects:

[0078] 1. The design of the elastic locking structure 5 enables the Housing 1 and the PCB board to be tightly fixed, effectively preventing the connector from loosening during the operation of the device or under external interference, ensuring the reliability of the connection, and reducing the probability of connection instability caused by the easy loosening of the connector.

[0079] 2. The overall structure design is simple and reasonable, and the number of components is relatively small. During assembly, only need to insert the PCB board in sequence, connect the wire harness 4 and complete the snap fixation, which is simple and fast to operate; at the same time, when maintenance or component replacement is required, it can also be quickly disassembled and reassembled, reducing the maintenance difficulty and cost.

[0080] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly.
