[0022] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / connections involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. For example, fixed connections / fixed installations can use screw connections, bolt connections, pin connections, key connections, adhesive connections, mortise and tenon connections, welding, riveting, etc., as needed. For detachable connections, screw connections, bolt connections, threaded connections, snap-fit ​​connections, mortise and tenon connections, Velcro connections, etc., can be used as needed. The various technical features in this utility model can be combined interactively without contradicting each other.

[0023] Please see Figure 1-3 The preferred embodiment of this utility model provides a piercing connector, including a housing 1, a wire 2, a top cover 3, and a piercing terminal 4 with a pointed end. The pointed end of the piercing terminal 4 is used to connect with the wire 2, and the connection point between the two is located between the housing 1 and the top cover 3. The cooperation between the housing 1 and the top cover 3 can protect the connection point between the wire 2 and the piercing terminal 4, ensuring the connection strength between the wire 2 and the piercing terminal 4.

[0024] Specifically, the outer casing 1 is provided with a wire fixing groove 11 and two connecting holes 12. The wire 2 is installed in the wire fixing groove 11. The arrangement direction of the two connecting holes 12 is perpendicular to the length direction of the wire 2. The connecting holes 12 are provided to facilitate the connection of the connector with other external electronic components. The piercing terminal 4 is fixed in the outer casing 1, and the tip of the piercing terminal 4 extends out of the wire fixing groove 11 and passes through the wire 2. The upper cover 3 covers the opening of the wire fixing groove 11 and is connected to both the wire 2 and the outer casing 1. When manufacturing this piercing connector, the piercing terminal 4 is first fixed in the outer casing 1, and the tip of the piercing terminal 4 extends out of the wire fixing groove 11. Then the wire 2 is installed in the wire fixing groove 11. During this process, the tip of the piercing terminal 4 passes through the wire 2 and contacts the conductor inside the wire 2, ensuring that the wire 2 and the piercing terminal 4 are tightly connected. The whole connection process is simple and easy to operate, reducing the manufacturing difficulty.

[0025] To further facilitate manufacturing, an exposed conductor 21 is provided in the middle of the wire 2. The tip of the piercing terminal 4 is inserted through the conductor 21. The exposed conductor 21 has no insulation layer, which can reduce the resistance when the piercing terminal 4 is pierced, and make it easy to observe the connection between the piercing terminal 4 and the conductor 21, preventing the two from being misaligned.

[0026] There are two wires 2 and two piercing terminals 4. A baffle 111 is provided in the middle of the wire fixing groove 11 to divide the wire fixing groove 11 into two parts. The two wires 2 are located in the two parts of the wire fixing groove 11 respectively. The tips of the two piercing terminals 4 are respectively inserted into the two wires 2. The baffle 111 can separate the two wires 2, prevent them from getting tangled together, and facilitate wiring.

[0027] An extension plate 112 is provided on the side of the baffle 111 near the opening of the wire fixing groove 11. The extension plate 112 extends out of the opening of the wire fixing groove 11 and is connected to the upper cover 3. The extension plate 112 is used to connect the baffle 111 and the upper cover 3 to further facilitate the fixing of the upper cover 3.

[0028] In this embodiment, the piercing terminal 4 and the outer shell 1 are integrally molded by in-mold injection molding. The piercing terminal 4 and the outer shell 1 substrate are bonded in a molten state, which can prevent the two from delaminating, wrinkling, or falling off, and can ensure the sealing of the piercing terminal 4, thus providing a certain degree of waterproofing. Furthermore, in order to further ensure the effect of in-mold injection molding, the sidewall of the piercing terminal 4 is provided with a groove 41. The groove 41 is located inside the outer shell 1. During manufacturing, the injection molding liquid can automatically flow to the groove 41 and form a protrusion 42 that matches it at the groove 41, so that the molded outer shell 1 can be engaged with the piercing terminal 4 at the groove 41, further preventing the two from falling off.

[0029] The top cover 3, wire 2, and outer shell 1 are integrally molded using rubber-coated injection molding. After the wire 2 is snapped into the wire fixing groove 11, rubber-coated injection molding is performed at the opening of the wire fixing groove 11. The injection molding liquid can automatically flow into the gaps of the wire fixing groove 11, so that the molded top cover 3 can firmly cover the connection between the wire 2 and the piercing terminal 4, which helps to improve the compactness of the entire connector. Furthermore, in order to improve the effect of rubber-coated injection molding, two connecting grooves 113 extend from the side wall of the wire fixing groove 11. The arrangement direction of the two connecting grooves 113 is perpendicular to the length direction of the wire 2, and the wire 2 and the two connecting grooves 113 are spaced apart. When the top cover 3 is injection molded, the injection molding liquid can flow into the two connecting grooves 113, further improving the connection strength between the top cover 3 and the wire fixing groove 11.

[0030] In this embodiment, the tip of the piercing terminal 4 is set as a cone. The cone structure disperses the concentrated stress during piercing, reduces the pressure required for insertion, and further facilitates manufacturing.

[0031] In other embodiments, the tip of the piercing terminal can be set as a wedge shape. After piercing the wire, the wedge structure generates greater radial pressure by utilizing the principle of the inclined plane, resulting in a tighter metal-to-metal contact between the piercing terminal and the wire, reducing contact resistance and improving conductivity.

[0032] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
