Description

Technical Field

[0001] This utility model relates to the field of connectors, and more specifically to a recessed connector structure. Background Technology

[0002] Existing recessed connectors typically consist of an insulator (frame or body) and a terminal assembly. To achieve the recessed effect, the insulator is usually attached to the circuit board, and one end of the terminal assembly is soldered to the circuit board, thus fixing the entire connector to the circuit board.

[0003] However, under high-intensity use, since the recessed connector needs to face a large amount of insertion and extraction forces from the side, simply relying on adhesion will cause the insulator to detach from the circuit board under the pull of external forces, thus causing the entire connector to fail. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a recessed connector structure, including a circuit board with a hollowed-out mounting groove. A terminal block is disposed within the mounting groove, and the terminal block includes a frame fixed to the top edge of the mounting groove. Several partitions are arranged at preset intervals within the frame, dividing the interior of the frame into several receiving slots. A connecting terminal is disposed within each receiving slot. A positioning frame protrudes downward from the bottom of the frame. When the frame is fixed to the mounting groove, the outer wall of the positioning frame engages with the mounting groove and is tightly fitted against the inner wall of the mounting groove.

[0005] Furthermore, the frame and the positioning frame are integrally formed. The frame includes a connecting part and a fitting part. The connecting part is used to fix the connecting terminal. When the frame is assembled with the mounting groove, the fitting part fits and fixes the top edge of the mounting groove.

[0006] Furthermore, a plurality of protrusions are provided at the bottom of the fitting part, and when the fitting part is fitted and fixed to the edge of the top of the mounting groove, the protrusions are fixed to the top of the mounting groove.

[0007] Furthermore, one end of the connecting terminal is fixed to the circuit board, and the other end extends through the terminal block into the receiving groove. The connecting terminal includes a fixing part, a bending part, and an elastic part. One end of the fixing part is fixed to the circuit board, and the connecting part surrounds the fixing part.

[0008] Furthermore, the bent portion extends into the receiving groove along the fixed portion and bends toward the bottom of the circuit board, and the elastic portion is disposed at the end of the bent portion away from the fixed portion, and the elastic portion protrudes toward the bottom of the circuit board.

[0009] Furthermore, reinforcing ribs are provided on the curved portion.

[0010] Furthermore, limiting portions are provided on both sides of the fixing portion, and the connecting portion is wrapped around the limiting portions.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This application provides a positioning frame that protrudes downwards from the bottom of the frame. When the terminal block is assembled with the circuit board, the positioning frame can be inserted into the mounting groove and fit tightly against the inner wall of the mounting groove. Compared with the traditional terminal block and circuit board, which are only in contact, the connection between the terminal block and the circuit board can be more secure when facing high-intensity insertion and removal, and it is not easy for the terminal block to fall off.

[0018] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0019] The preferred embodiments of this utility model will now be further described with reference to the accompanying drawings. Figure 1 and Figure 2As shown, the recessed connector structure includes a circuit board 100 with a hollowed-out mounting groove 110. A terminal block 200 is disposed within the mounting groove 110. The terminal block 200 includes a frame 210 fixed to the top edge of the mounting groove 110. Several partitions 220 are arranged at preset intervals within the frame 210, dividing the interior of the frame 210 into several receiving slots 230. A connecting terminal 300 is disposed within each receiving slot 230. A positioning frame 240 protrudes downward from the bottom of the frame 210. When the frame 210 is fixed to the mounting groove 110, the outer wall of the positioning frame 240 is engaged with the inner wall of the mounting groove 110.

[0020] During installation of this embodiment, different connecting terminals 300 and terminal blocks 200 are first combined by injection molding, so that the different connecting terminals 300 are inserted into different receiving slots 230. Then, the terminal blocks 200 are assembled with the circuit board 100. During the assembly process, the frame 210 is fixed to the top edge of the mounting slot 110, and the positioning frame 240 is directly embedded in the mounting slot 110 and tightly fitted with the inner wall of the mounting slot 110. Then, the connecting terminals 300 are welded to the circuit board 100, so that the connection between the terminal blocks 200 and the circuit board 100 is more secure.

[0021] This application provides a positioning frame 240 that protrudes downward from the bottom of the frame 210. When the terminal block 200 is assembled with the circuit board 100, the positioning frame 240 can be inserted into the mounting groove 110 and tightly fitted with the inner wall of the mounting groove 110. Compared with the traditional terminal block 200 and circuit board 100, which are only in contact, the connection between the terminal block 200 and the circuit board 100 can be more secure when facing high-intensity insertion and removal, and it is not easy for them to fall off.

[0022] Furthermore, based on the above embodiments, such as Figure 3 As shown, the frame 210 and the positioning frame 240 are integrally formed. The frame 210 includes a connecting part 211 and a fitting part 212. The connecting part 211 is used to fix the connecting terminal 300. When the frame 210 is assembled with the mounting groove 110, the fitting part 212 fits and fixes the top edge of the mounting groove 110. Thus, when the connecting terminal 300 is injection molded with the terminal base 200, the connecting part 211 wraps around the connecting terminal 300, thereby fixing the connecting terminal 300 on the frame 210.

[0023] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 3As shown, a plurality of protrusions 212a are provided downwardly at the bottom of the fitting part 212. When the fitting part 212 is fitted and fixed to the edge of the top of the mounting groove 110, the protrusions 212a are fixed to the top of the mounting groove 110. The protrusions 212a can provide support for the frame 210 on the top of the circuit board 100.

[0024] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 4 As shown, one end of the connecting terminal 300 is fixed to the circuit board 100, and the other end extends through the terminal block 200 into the receiving groove 230. The connecting terminal 300 includes a fixing part 310, a bending part 320 and an elastic part 330. One end of the fixing part 310 is fixed to the circuit board 100, and the connecting part 211 is wrapped around the fixing part 310, thereby fixing the entire connecting terminal 300 to the frame 210.

[0025] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 4 As shown, the bent portion 320 extends into the receiving groove 230 along the fixed portion 310 and bends towards the bottom of the circuit board 100. The elastic portion 330 is disposed at the end of the bent portion 320 away from the fixed portion 310, and the elastic portion 330 protrudes towards the bottom of the circuit board 100. When connected to an external device, the external device will press the elastic portion 330 from one side of the circuit board 100, causing the elastic portion 330 to enter the receiving groove 230 with the cooperation of the bent portion 320. When the external device is removed, the elastic portion 330 will protrude again from the bottom of the circuit board 100.

[0026] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 4 As shown, a reinforcing rib 321 is provided on the bent portion 320. The reinforcing rib 321 can increase the bending strength of the bent portion 320, so that when the bent portion 320 moves in conjunction with the elastic portion 330 under high strength, it is not easy to suffer metal fatigue and breakage.

[0027] Furthermore, based on the above embodiments, combined with Figure 1 and Figure 4As shown, limiting portions 311 protrude outward from both sides of the fixing portion 310, and the connecting portion 211 surrounds the limiting portions 311. The number of limiting portions 311 can be one or two, and no specific limitation is made here. When the connecting terminal 300 is combined with the terminal base 200 by injection molding, the limiting portions 311 can increase the injection area between the connecting terminal 300 and the connecting portion 211, thereby enhancing the connection strength between the connecting terminal 300 and the terminal base 200 after injection molding.

[0028] The details of the above exemplary embodiments are provided, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Therefore, it is intended that all changes falling within the meaning and scope of equivalents of the claims be included within the present invention.
