Description

Technical Field

[0001] The utility model relates to the field of electrical connection, in particular to a flexible row electrical connector. Background Art

[0002] With the development trend of miniaturization and lightness of consumer electronic products such as notebooks, tablets, and mobile phones, the design and manufacturing process of their components are becoming more and more demanding. As the products become thinner and lighter, the internal space becomes very narrow, which requires that the internal layout of the product must be densely packed. The size of each electronic component is also getting smaller and smaller, and thinner and lighter. The reliability requirements for process technology and product connections are getting higher and higher. For example, the FPC flexible row (flexible board or wire row) connector is a commonly used small electrical connector, which is used to plug in the FPC flexible row (flexible board or wire row) to achieve electrical connection. There are currently two main ways to insert the FPC flexible row: horizontal insertion and vertical insertion. After the FPC flexible row is inserted, the metal shell is rotated to achieve snap-on fixation. However, these two insertion methods have certain angle restrictions and will take up more circuit board space in some application scenarios. Utility Model Content

An inner recess 19 is provided on the outer side surface of the recessed platform 16. Preferably, the side wall 13 is further provided with an inner stop wall 17 located at the inner side of the mounting groove 15, the inner stop wall 17 is integrally connected to the rear end wall 12, and the top surface of the inner stop wall 17 is lower than the top surface of the rear end wall 12, and the top surface of the inner stop wall 17 is provided with a protrusion 18 protruding upward as a whole, and the protrusion 18 is located on the inner side of the mounting groove 15 for limiting the butt-end component 200 (such as an FPC soft row or a circuit board). Preferably, the rear end wall 12 is flush with the top surface of the side wall 13 .

[0020] The terminal 20 is provided with a horizontal arm 21, an arc-shaped contact arm 22 extending forward from the horizontal arm 21, and a welding arm 23 extending backward from the horizontal arm 21. The horizontal arm 21 is integrally embedded in the rear end wall 12 to fix the terminal 20 on the insulating body 10, and the arc-shaped contact arm 22 extends into the frame opening 14 to be crimped and contacted with the mating terminal component 200 (such as an FPC flexible row or a circuit board). The welding arm 23 extends backward and protrudes from the rear end wall 12 to be welded to a circuit board (not shown).

[0021] The metal shell 30 is provided with a main cover 31 covering the rear end wall 12, and a pair of side covers 38 bent downward from both ends of the main cover 31. The main cover 31 is narrow and long, and the front edge of the main cover 31 is provided with an upwardly tilted folded edge 32 and a pair of openings 33 at both ends of the folded edge 32, wherein the angle A between the tilted direction of the folded edge 32 and the horizontal direction is 20-40 degrees, and the reference Figure 4 As shown, the side cover 38 is integrally stamped with the main cover 31, and the side cover 38 includes a main arm 34, a pair of fixing arms 37 extending downward from the main arm 34, and a bent portion 35 extending from the front end of the main arm 34 backward. The main arm 34 extends horizontally in the front-to-back direction to be clamped in the mounting groove 15, and the pair of fixing arms 21 are distributed front to back, wherein the fixing arm 21 on the rear side is vertically inserted downward into the mounting groove 15, and the fixing arm 21 on the front side is vertically inserted downward into the inner recess 19, and the pair of fixing arms 21 both protrude downward from the bottom surface of the side wall 13 to be fixed on the circuit board. Figure 1 and Figure 2 The bending portion 35 is formed at the end of the main arm 34, and a U-shaped operating portion 36 is formed at the connection between the bending portion 35 and the main arm 34, and the end of the bending portion 35 abuts against the protruding portion 18, and the end of the bending portion 35 is provided with an inverted U-shaped stopper 351 extending upward, and the stopper 351 protrudes inward to stop above the docking end element 200 (such as an FPC flexible row or a circuit board), and is used to limit the docking end element in the vertical direction. Preferably, the bottom edges of the main arm 34 and the bending portion 35 abut against the recessed platform 16, and the U-shaped operating portion 36 protrudes forward from the side wall 13, and is used as an operating portion for operation. By pushing the U-shaped operating portion 36 outward, the main arm 34 of the side cover 38 can be turned outward and stretched, thereby facilitating the loading and unloading of the docking end element 200.

When the butt-end element 200 needs to be pulled out, it is only necessary to bend the U-shaped operating portion 36 outward (such as Figure 1 The main arm 34 expands outwards, thereby causing the stopper 351 to break away from the limit of the butt-end component 200, so that the butt-end component 200 can be flipped up and the electrical connector 100 can be pulled out.

[0023] In summary, the electrical connector of the utility model can meet the application requirements of oblique insertion of the FPC flexible row by optimizing the structure of the metal shell 30, and at the same time uses the side cover 38 to achieve limited fixation with the circuit board and the docking end component 200 to ensure the stability of the contact, and the overall structure is relatively simple and easy to operate.
