Description

Technical Field

[0001] This utility model relates to the field of electrical connections, and more particularly to a connector. Background Technology

[0002] Electrical connectors are essential components widely used in various electronic devices for telecommunication transmission. They are not only prevalent in digital devices such as mobile phones and computers, but also extensively used in the automotive and industrial sectors. Depending on the application scenario, electrical connectors require different design specifications. For automotive connectors, reliability and transmission stability are crucial, as these directly impact vehicle safety. Compared to connectors in consumer electronics, automotive connectors operate in harsher environments, frequently encountering rain, sandstorms, high temperatures, and vibrations. If the retention force between the terminals and the insulating body within an automotive connector is insufficient, loosening can occur, leading to poor contact or transmission interruption. Therefore, careful design of the terminals and insulating body is essential to ensure a more reliable and secure connection. Utility Model Content

[0008] Furthermore, the inner and outer baffles of the end wall have the same thickness and are sandwiched between the inner and outer sides of the metal terminal, and the snap-fit ​​protrusion is formed on the inner surface of the inner baffle facing the slot.

[0009] Furthermore, a guide ramp is formed on the rear edge of both the inner baffle and the sidewall, and the guide ramp surrounds the cavity.

[0010] Furthermore, the thickness of the metal terminal is greater than or equal to the sum of the thicknesses of the inner baffle wall and the outer baffle wall.

[0017] Please see Figures 1 to 3 As shown, this utility model provides a connector, including an insulating body 10 and a pair of metal terminals 20 housed within the insulating body 10. The insulating body 10 and the metal terminals 20 are installed and coupled to each other and fixedly mounted on a circuit board (not shown).

[0018] The insulating body 10 is a cuboid, having a pair of sidewalls 11, a pair of endwalls 12, and a chamber 13 formed inside the sidewalls 11 and endwalls 12. The sidewalls 11 and endwalls 12 are integrally injection molded, and the pair of sidewalls 11 and the pair of endwalls 12 are also parallel to each other. The chamber 13 is square, located between the pair of sidewalls 11, and extends through the insulating body 10 from front to back. Preferably, the pair of sidewalls 11 and the pair of endwalls 12 are flush in the front-back direction, that is, the front edge of the sidewall 11 is flush with the front edge of the endwall 12, and the rear edge of the sidewall 11 is also flush with the rear edge of the endwall 12. A pair of through slots 14 are formed on the pair of end walls 12, extending from front to back. The slots 14 are formed within the end walls 12 and extend along both the front and rear surfaces of the end walls 12, for inserting the metal terminal 20. Preferably, the pair of slots 14 are located at the longitudinal ends of the chamber 13. Due to the presence of the slots 14, the end walls 12 are divided into an outer baffle wall 15 and an inner baffle wall 16. The inner baffle wall 16 is located between the slots 14 and the chamber 13, and together with the pair of side walls 11, it forms the chamber 13. The slots 14 are located between the inner baffle wall 16 and the outer baffle wall 15. Preferably, a guide ramp 17 is formed on the rear edge of both the inner baffle wall 16 and the side wall 11, and the guide ramp 17 surrounds the chamber 13. Furthermore, the slots 14 are square and exposed on the rear surface of the end walls 12, allowing the metal terminal 20 to be inserted from back to front.

[0019] Preferably, the end wall 12 is further provided with at least one snap-fit ​​protrusion 18 extending into the slot 14. The snap-fit ​​protrusion 18 is formed on the inner surface of the inner baffle wall 16 facing the slot 14, and is used to snap and fix the metal terminal 20 in the slot 14. One side of the snap-fit ​​protrusion 18 has an inclined guide surface 19, which makes the insertion of the metal terminal 20 smoother. Of course, the snap-fit ​​protrusion 18 can also be formed on the inner surface of the outer baffle wall 15, which will not be described in detail here. The inner baffle wall 16 and the outer baffle wall 15 of the end wall 12 have the same thickness and are sandwiched between the inner and outer sides of the metal terminal 20.

[0020] The metal terminal 20 is sheet-shaped, comprising a main body 21 and a mounting portion 22. The main body 21 and the mounting portion 22 form a T-shaped structure. The width of the main body 21 is smaller than the width of the mounting portion 22, such that the two sides of the mounting portion 22 protrude outward from the two side edges of the main body 21. Preferably, the thickness of the main body 21 is the same as the thickness of the mounting portion 22, and each side edge of the main body 21 is provided with at least one protrusion 23. The protrusion 23 is inserted into the slot 14 and then engaged and fixed with the end wall 12. Preferably, the thickness of the metal terminal 20 is greater than or equal to the sum of the thicknesses of the inner baffle wall 16 and the outer baffle wall 15. In addition, to enhance the bonding force between the metal terminal 20 and the insulating body 10, the metal terminal 20 is provided with at least one limiting recess 24. The limiting recess 24 is recessed from the surface of the main body 21. When the main body 21 is inserted into the slot 14, it will engage with the snap-fit ​​protrusion 18 in the slot 14 to limit the bonding, thereby further enhancing the bonding between the metal terminal 20 and the insulating body 10. Preferably, the limiting recess 24 is located at the end of the main body 21 and faces the inner baffle wall 16. Preferably, the mounting part 22 is located outside the slot 14, and the mounting part 22 has a welding surface 25 facing away from the slot 14 for welding and fixing to a circuit board. The free ends of the mounting part 22 are flush with the top wall 11.

[0021] In summary, the connector 100 of this utility model optimizes the structure of the insulating body 10 and the metal terminal 20 by providing an additional snap-fit ​​protrusion 18 in the insertion groove within the end wall 12 of the insulating body 10, which engages and fixes with the limiting recess 24 on the metal terminal 20. Thus, the overall structure of the protrusion 23, the limiting recess 24, and the snap-fit ​​protrusion 18 improves the bonding force between the metal terminal 20 and the insulating body 10, effectively improving the problem of loose connection of the metal terminal 20 under bumpy and vibrating conditions.
