[0014] The concept, specific structure and technical effects of the utility model will be further described below in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the utility model.
[0015] It should be noted that, in the description of the present invention, terms such as "up", "down", "left", "right", "vertical", "horizontal", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.
[0016] See also Figure 1 , 2, as shown in FIGS. 3, is a schematic diagram of a preferred embodiment of the present invention. The present invention relates to a PCB board piercing terminal for wiring on a PCB board. It has a conductive main body 1. The main body 1 of this embodiment is an integrally formed frame body by stamping. The main body 1 includes a bottom plate 11 and a rear vertical plate 12, an upper top plate 13, and a front vertical plate 14 that extend from the rear side edge of the bottom plate 11 and are continuously bent. And there is a gap between the lower side edge of the front vertical plate 14 and the bottom plate 11, so that the front vertical plate 14 has mobility; the inside of the main body 1 is hollow, forming a shape like a Chinese character "hui", having good structural elasticity. The bottom plate 11 is used to be mounted on the PCB board 2, so that the main body 1 is positioned on the PCB board 2 and presents a preset posture. A grooved channel 131 adapted for the embedding of a wire 3 is provided on the upper top plate 13. The grooved channel 131 cuts the upper top plate 13 and the front vertical plate 14 to form two spaced left and right parts. Preferably, the grooved channel 131 divides the upper top plate 13 and the front vertical plate 14 into two equal left and right parts, and can present corresponding elastic movement relative to the rear vertical plate 12; the rear end of the grooved channel 131 extends in the direction of the rear vertical plate 12 and stops on the rear vertical plate to form a wire trough 121. The wire trough 121 defines the embedding depth of the wire and restricts the left and right movement of the wire, providing support for the assembly of the wire. A piercing member 15 is also provided on the cut part of the front vertical plate 14. The piercing member 15 has a piercing part 151 for piercing the insulating layer 31 of the wire 3 and a contact part 152 for electrically contacting the core part 32 of the wire 3. The piercing part 151 pierces the insulating layer 31 of the wire by means of the external force of the wire 3 embedded in the grooved channel 131, so that the core part 32 of the wire 3 is exposed and contacts and connects with the contact part 152. It realizes the connection of the wire by piercing, reduces the process of stripping the outer insulating layer of the wire and then soldering with tin, improves the wiring convenience of the PCB board, and also has replaceability.
[0017] Figure 1 , 2 , as shown in FIGS. 3, in this embodiment, the piercing member 15 is a blade formed by locally thinning the front vertical plate 14. There are two piercing members 15 and they are in the form of two closed doors, thereby obtaining better clamping force. After the wire 3 is embedded, it is clamped left and right by the two piercing members 15 to maintain a stable connection and prevent accidental loosening. The piercing part 151 and the contact part 152 are the edges of the corresponding sides of the piercing member 15, and the piercing part 151 and the contact part 152 are connected in sequence from top to bottom along the embedding direction of the wire 3, so that the piercing and electrical connection work are organically connected, improving the wiring efficiency and convenience. In this embodiment, the orthographic projection of the grooved channel 131 falls on the middle area of the bottom plate 11 in the left and right directions, and convex feet 111 extending outward are respectively provided on the left and right sides of the bottom plate 11, and the left and right convex feet 111 are symmetric with respect to the midline of the projection of the grooved channel 131. The design of the left and right convex feet 111 increases the stability of the bottom plate 11 standing, is not easy to sway left and right, and is conducive to the wire 3 being embedded in the grooved channel 131.
[0018] Figure 4 , 5 As shown, when in use, there is a corresponding pad 21 on the PCB board 2, and the bottom plate 11 of the main body 1 is attached to the pad 21 for welding, so that the main body 1 is positioned on the PCB board 2 and forms a conductive connection with the corresponding circuit. The convex feet 111 on the left and right sides of the bottom plate 11 increase the attachment area with the pad 21, further improving the stability of the bottom plate 11 standing on the PCB board 2. At the same time, the convex feet 111 further increase the tin absorption, thereby improving the welding firmness and electrical connectivity. The wire 3 can be pressed into the groove 131 from top to bottom by hand, auxiliary tools or a manipulator, and a part of the wire 3 is embedded between the two piercing members 15. At this time, the elastic self-adaptive adjustment of the upper top plate 13 and the front vertical plate 14 is utilized to cooperate with the embedding assembly of the wire 3, and the piercing portion 151 on the piercing member 15 pierces the insulating layer 31 of the wire with the help of the external force of the wire 3 embedded in the groove 131, so that the core 32 of the wire 3 is exposed and contacted and connected with the contact portion 152, thereby completing the connection between the wire 3 and the PCB board 2, reducing the process of stripping the outer insulation layer of the wire and then tinning and soldering, improving the convenience of PCB board wiring, and also having detachability, while the terminal can provide reliable electrical connectivity and durability.

For those skilled in the art, many equivalent improvements and changes can be made to the above embodiments through logical analysis, reasoning or limited experiments without exceeding the concept and scope of the present invention, but these improvements and changes should all fall within the scope of protection required by the present invention.
