Description

Technical Field

[0001] The utility model relates to the field of computer mainboard connection components, in particular to a board-end connector for realizing automatic assembly of a computer cooling fan. Background Art

[0002] In the prior application, in order to adapt to automated assembly, a connector for the wire end was previously applied for, see patent publication number: CN118539192A for details. The patent name is: A connection component for the motherboard of an automated assembly system. The function of the connection component is to facilitate the automatic robot to grasp and directly connect with the gold fingers of the motherboard. However, in actual application, since the computer motherboard is large and has many pads on the surface, directly plating gold on the computer motherboard to make gold fingers is actually immersing the motherboard in a gold plating solution and plating gold on each pad, which is costly and not stable enough compared with the connection component disclosed in the comparative document. Utility Model Content

A plurality of terminals are arranged in the frame-shaped structure. The bottom surface of the terminal is flush with the bottom surface of the thin body. The bottom surface of the terminal is pressed on the soldering pad of the mainboard and is electrically connected to the soldering pad.

[0004] Preferably, the terminal is connected to the pad via soldering.

[0005] Preferably, the terminal comprises an elongated body, and protrusions are provided at both ends of the elongated body, and the protrusions are clamped in the plastic part.

[0006] Preferably, a plurality of terminal holes are provided on both sides of the plastic part, and the protrusions are inserted into the terminal holes.

[0007] Preferably, the edge of the terminal located at the edge of the frame-shaped structure is embedded in the plastic part.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] Example 1

[0022] like Figure 1As shown, the utility model proposes a board-end connector for realizing automatic assembly of computer cooling fans, including a plastic part 1, which is a frame-shaped structure with a small thickness. A plurality of terminals 3 are arranged in the frame structure, and the terminal 3 includes an elongated body 4. The elongated body 4 has protrusions 5 at both ends, and the protrusions 5 are clamped in the plastic part 1. There are terminal 3 holes on both sides of the plastic part 1. The plastic part 1 and the terminals 3 are injection molded. The two ends of the terminals 3 are embedded in the plastic part 1 and fixed. In order to stabilize the structure, the terminals 3 arranged at the edge are also embedded in the plastic part 1 at the contact position with the inner wall of the frame structure, which can increase the structural stability of the entire product.

[0023] like Figure 3 As shown, the two ends of the terminal 3 are raised upward to facilitate fixing in the middle of the plastic body. The flat position of the lower surface of the terminal 3 is flush with the plastic body, ensuring that when the plastic body is placed on the main board 2, the terminal 3 can be pressed on the pad of the main board 2. The electrical connection between the terminal 3 and the main board 2 can be achieved by spot welding the lower surface of the terminal 3 to the pad of the main board 2 through soldering, as shown in FIG. Figure 2 As shown, at least two groups of positioning posts 8 are provided at the bottom of the plastic part 1 , and two holes are opened on the main board 2 to facilitate the insertion of the positioning posts 8 , thereby ensuring that the connector and the main board 2 are connected and aligned.

[0024] The square holes provided above and below the positions where the two ends of the terminal 3 engage with the plastic body are injection molding process holes, which are used to press the terminal 3 with the mold insert during injection molding to prevent the terminal 3 from shifting during injection molding.

[0025] By using this connector, the consumption of gold on the gold-plated fingers on the surface of the motherboard 2 is reduced, which greatly reduces the cost. In addition, the connection between this connector and the line end connector is simple, such as Figure 6 As shown, after the line end connector is grabbed by the robot, the terminal 3 of the line end connector is directly pressed onto the terminal 3 of this connector, and the line end connector is fastened to the mainboard 2 with screws, thereby realizing the connection between the product and the mainboard 2, which is suitable for automated assembly.

[0026] Example 2

[0027] like Figure 4 、 Figure 5As shown, it includes a plastic part 1, which is a frame-shaped structure with a small thickness. A number of terminals 3 are arranged in the frame structure, and reinforcing ribs 9 are provided between adjacent terminals 3. The terminal 3 includes an elongated body 4, and a protrusion 5 is provided at both ends of the elongated body 4. The protrusion 5 is clamped in the plastic part 1. There are terminal 3 holes on both sides of the plastic part 1. The plastic part 1 and the terminal 3 are injection molded. The two ends of the terminal 3 are embedded in the plastic part 1 and fixed. In order to stabilize the structure, the terminals 3 arranged at the edge are also embedded in the plastic part 1 at the contact position with the inner wall of the frame structure, which can increase the structural stability of the entire product. The reinforcing ribs 9 are integrally formed within the frame structure. The ribs 9 are aligned with the length of the terminals 3. The ribs 9 can be slightly higher than the thickness of the plastic body frame structure. Furthermore, the ribs 9 limit the width of the adjacent terminals 3. The ribs 9 increase the strength of the entire connector. Since the plastic body is relatively thin, the terminals 3 may warp slightly in the length direction. The ribs 9 increase the force of the plastic body in the length direction of the terminals 3, solving the warping problem of thin components. The remaining structure is consistent with that of Example 1 and will not be repeated in this embodiment.
