[0035] It should be noted that the features in the embodiments of the present invention can be combined with each other without conflict.

[0036] Please refer to Figure 1 , in the embodiment of the present application, a solderless connector 10 is provided. The solderless connector 10 is used to connect to a PCB board and is used to connect to a cable, so as to achieve the purpose of electrically connecting the cable and the PCB board. Among them, the solderless connector 10 can solve the problem that the rotation during the cable assembly process in the prior art may cause the pads on the PCB board to be torn off.

[0037] In this embodiment, please refer to Figure 2 and Figure 3 , the solderless connector 10 includes a connector base 100, a double-female adapter 200, and a locking member 300. The connector base 100 includes a first connection body 110 and a second connection body 120; the first connection body 110 is used to fit on the PCB board, and a through hole is provided on the first connection body 110 for a screw 111 to pass through to achieve the fixed connection between the first connection body 110 and the PCB board when the screw 111 is connected to the PCB board; the second connection body 120 is cylindrical, and the first connection body 110 is provided at one end of the axial direction of the second connection body 120; assembly grooves 121 and receiving grooves 122 are respectively provided at both axial ends of the second connection body 120. Please refer toFigure 3 and Figure 5 , a connection terminal 1211 is provided in the assembly groove 121, and a pin core 1221 is provided in the receiving groove 122. The pin core 1221 is used for electrically connecting with the PCB board. The double-female adapter 200 is assembled in the assembly groove 121; both ends of the double-female adapter 200 along its axial direction are respectively provided with a first groove 210 and a second groove 220. Referring to Figure 3 and Figure 4 , a first electrical connection terminal 211 is provided in the first groove 210, and a second electrical connection terminal 221 is provided in the second groove 220; the first electrical connection terminal 211 is electrically connected with the connection terminal 1211, and the second electrical connection terminal 221 is used for externally connecting a cable. The locking member 300 is detachably connected to the double-female adapter 200 to lock the double-female adapter 200 and the second connection body 120.

[0038] Please refer to FIG. 2. The steps for the solderless connector 10 to be assembled on the PCB board to achieve electrical connection of the cable can be as follows: First, attach the first connection body 110 to the PCB board, and realize the fixed connection between the first connection body 110 and the PCB board by passing the screw 111 through the first connection body 110. Then, screw the double-female adapter 200 into the assembly groove 121, and at the same time realize the electrical connection between the first electrical connection terminal 211 and the connection terminal 1211. Next, screw the locking member 300 into one end of the double-female adapter 200 close to the second connection body 120, so that the locking member 300 is close to the second connection body 120 to realize the locking of the double-female adapter 200. Finally, the cable can be screwed into the end of the double-female adapter 200 far from the second connection body 120, so that the cable is electrically connected with the second electrical connection terminal 221, and the electrical connection between the cable and the PCB board is realized.

[0039] As described above, when the solderless connector 10 is assembled on the PCB board, since the first connection body 110 is attached to the PCB board and fixed by the screw 111, it is thus made that the whole connector base 100 is firmly connected to the PCB board. Based on this, in the case of screwing the cable onto the double-female adapter 200, the situation that the connector base 100 rotates along with it can be avoided, and the situation that the pin core 1221 on the second connection body 120 rotates and causes the pads on the PCB board to be torn off can also be avoided. Based on this, the solderless connector 10 provided by the present invention can improve the problem that the rotation during the cable assembly process in the prior art causes the pads on the PCB board to be torn off.

[0040] In this embodiment, the locking member 300 is threadedly connected to the double-female adapter 200.

[0041] Further, a plurality of spaced third grooves 310 are provided on one side of the locking member 300 away from the second connection body 120.

[0042] In this embodiment, the first connection body 110 is plate-shaped, and planes are formed on both sides in the thickness direction of the first connection body 110, and one of the planes is used to fit onto the PCB board. Setting the first connection body 110 to be plate-shaped can facilitate the fitting connection between the first connection body 110 and the PCB board.

[0043] To further improve the connection stability between the first connection body 110 and the PCB board, optionally, in this embodiment, the solderless connector 10 further includes a clamping plate 112. The clamping plate 112 is connected to the screw 111 and jointly clamps the PCB board with the first connection body 110. That is to say, during the process of assembling the first connection body 110 onto the PCB board, the PCB board can be first clamped by the first connection body 110 and the clamping plate 112, and then the screw 111 is sequentially passed through the first connection body 110, the PCB board, and the clamping plate 112, so that the clamping plate 112 and the first connection body 110 jointly clamp the PCB board. Among them, by jointly clamping the PCB board by the clamping plate 112 and the first connection body 110, the connection stability between the first connection body 110 and the PCB board can be further improved, preventing the pin core 1221 from rotating during the process of screwing in the cable, and further preventing the solder pads on the PCB board from being torn off.

[0044] It should be noted that the first connection body 110 and the clamping plate 112 can be adapted to PCB boards of various thicknesses. In other words, through the clamping action of the clamping plate 112 and the first connection body 110, the solderless connector 10 can be assembled and connected to PCB boards of various thicknesses, improving the versatility of the solderless connector 10.

[0045] Optionally, please refer to Figure 2 and Figure 6 , a viewing window 113 is further opened on the first connection body 110. The viewing window 113 penetrates the first connection body 110, and the pin core 1221 is arranged corresponding to the viewing window 113. The pin core 1221 being arranged corresponding to the viewing window 113 means that when the viewing window 113 is in an open state, the operator can see the pin core 1221 through the viewing window 113, thereby facilitating the operator to observe the pin core 1221 through the viewing window 113 and thus facilitating the judgment of whether the pin core 1221 is aligned.

[0046] Furthermore, the solderless connector 10 further includes a plugging member 1131, and the plugging member 1131 is detachably connected to the viewing window 113. Generally, the viewing window 113 can be plugged by the plugging member 1131 to prevent other substances from the outside from entering through the viewing window 113 and affecting the pin core 1221, providing a protection effect for the pin core 1221. When it is necessary to observe the pin core 1221 through the viewing window 113, the plugging member 1131 can be taken out from the viewing window 113.

[0047] It should be noted that in some embodiments, the plugging member 1131 can be set to a transparent structure, so that while providing protection to the needle core 1221, it is convenient for the operator to observe the needle core 1221 through the visual window 113.

[0048] In other embodiments, the setting of the plugging member 1131 can also be cancelled.

[0049] In addition, in this embodiment, the visual window 113 is a cylindrical threaded hole, the plugging member 1131 is provided with threads, and the plugging member 1131 is in threaded cooperation with the visual window 113. The assembly of the plugging member 1131 and the visual window 113 is realized by means of threaded connection, with a simple structure and easy implementation; moreover, the threads of the plugging member 1131 and the visual window 113 can provide a self-locking function, improving the installation stability of the plugging member 1131 and the visual window 113. Further, when the plugging member 1131 cooperates with the visual window 113, a part of the plugging member 1131 exposes outside the first connection body 110, and the part that exposes outside the first connection body 110 can be provided with an anti-slip structure (this part does not participate in the threaded cooperation of the visual window 113), for example, this part of the structure is set to be gear-shaped, etc.

[0050] In this embodiment, the connection terminal 1211 on the second connection body 120 and the needle core 1221 are coaxially arranged, and the connection terminal 1211 and the needle core 1221 are collinear with the central axis of the second connection body 120. In addition, in this embodiment, the first connection body 110 is arranged at the central position close to the end face of the second connection body 120. Based on this, in order to prevent the first connection body 110 from affecting the needle core 1221, an avoidance groove 114 for avoiding the needle core 1221 is opened on the first connection body 110, and the avoidance groove 114 penetrates through the first connection body 110 along the axial direction of the second connection body 120; the part of the needle core 1221 extending out of the receiving groove 122 is located inside the avoidance groove 114. The avoidance groove 114 can avoid the needle core 1221, facilitate the electrical connection between the needle core 1221 and the PCB board, and also prevent the needle core 1221 from being affected by the first connection body 110.

[0051] It should be understood that in other embodiments, if there is a certain distance between the center of the end face of the first connection body 110 and the second connection body 120, such that there is a certain distance between the first connection body 110 and the needle core 1221, the setting of the avoidance groove 114 can be cancelled.

[0052] In this embodiment, the first connection body 110 and the second connection body 120 are integrally formed.

[0053] In summary, when the solderless connector 10 is assembled on the PCB board, since the first connection body 110 is attached to the PCB board and fixed by screws 111, the connector housing 100 is integrally and firmly connected to the PCB board. Based on this, when the cable is screwed onto the double-female adapter 200, the situation where the connector housing 100 rotates accordingly can be avoided, and the situation where the pin core 1221 on the second connection body 120 rotates and tears off the pads on the PCB board can also be avoided. Based on this, the solderless connector 10 provided by the present utility model can improve the problem in the prior art that the rotation during the cable assembly process causes the pads on the PCB board to be torn off. Further, by jointly clamping the PCB board by the clamping plate 112 and the first connection body 110, the connection stability between the first connection body 110 and the PCB board can be further improved, preventing the pin core 1221 from rotating during the process of screwing in the cable, and further preventing the pads on the PCB board from being torn off. In addition, by providing a viewing window 113 on the first connection body 110, the connection state between the pin core 1221 and the PCB board can be observed through the viewing window 113, which is beneficial to confirming whether the pin core 1221 is aligned.

[0054] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present utility model should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope of the claimed rights.
