A WTB connector, including a plate end and a wire end, the wire end includes a plastic body and a plurality of terminals, one end of the terminal is bent to form a contact protrusion, and the other end has a flat solder cup for welding CABLE wires, A plurality of connecting terminals are clamped side by side in the plastic main body, and the contact protrusions of the connecting terminals are higher than the plastic main body, and after being engaged with the board end, the contact protrusions are electrically connected with the elastic contacts of the gold fingers on the board end.

Preferably, the width of the flat solder cup is greater than that of the connection terminal.

Preferably, the surface of the flat solder cup has inverted triangular grooves.

Preferably, the plastic body is a square structure, which has a front face, a rear end face and a top face, and a plurality of slots are arranged side by side on the top face, and one end of the slot penetrates to the front face, so that the terminal face into the slot.

Preferably, limiting grooves are provided on the two side walls of the slot corresponding to the positions of the flat welding cups, and the two sides of the flat welding cups are locked in the limiting grooves.

Preferably, both sides of the plastic body are provided with protrusions matching the board ends.

Beneficial effects: a WTB connector disclosed by the utility model has the following beneficial effects: the structure of the wire end is optimized, and one end of the terminal is directly stamped into a flat welding cup structure to realize the welding and fixing of the cable. Compared with riveting The joint structure has better contact, more convenient assembly, and higher connection firmness. The plastic main structure has also been optimized to ensure the stable installation of the terminal and avoid falling off after multiple plugs and pulls.

Detailed ways

In order to further understand the utility model, the preferred embodiments of the utility model are described below in conjunction with the accompanying drawings and examples, but it should be understood that these descriptions are only to further illustrate the features and advantages of the utility model, rather than limiting the utility model claims .

As shown in Figure 1, a WTB connector described in the utility model includes a board end 1 and a wire end 2, the board end is welded and fixed on the PCB board, and the wire end is connected to the CABLE cable, and then the wire end Plugged into the board end to complete the electrical connection.

The structure of the wire end is shown in Figures 2-4, including a plastic body 21 and a plurality of terminals 22, the plurality of terminals are clamped side by side in the plastic body, one end of which is welded to a CABLE cable, and the other end is protruding and connected to the board end. Gold finger electrical connection.

Specifically, the plastic body is a square structure, with a front end surface 211, a rear end surface 212 and a top surface 213, and a plurality of slots 214 for clamping terminals are arranged side by side on the top surface, and one end of the slot runs through To the front face, so that the plug-in terminal can be inserted into the slot from the front face, and the two sides of the top face are also provided with assembly grooves 215, which cooperate with the assembly strips on the board end to realize the fool-proof assembly of the two, and at the same time The two side walls of the plastic main body are also provided with protrusions 216 that match the plate ends to prevent the two from being separated after being inserted.

The connecting terminal is made of conductive material, which is inserted into the slot. One end of the connecting terminal is bent to form a contact protrusion 221. The contact protrusion is higher than the plastic main body, so as to facilitate elastic electrical contact with the gold finger on the board end. The other end of the connecting terminal has a flat welding cup 222 for welding the CABLE cable. The flat welding cup has a widened structure, and its width is greater than the width of the connecting terminal itself. The widened structure facilitates firm welding of the cable end. There is an inverted triangular groove 223 on the surface of the flat solder cup. The groove is against the plastic body after the terminal is assembled to ensure the firmness of the terminal after insertion. At the same time, the groove can increase the amount of solder when welding CABLE cables to improve welding firmness.

The connecting terminal is inserted into the slot from the front face of the plastic main body. In order to improve the firmness of insertion, limit grooves 217 are provided on the two side walls of the slot corresponding to the positions of the flat solder cups, and the two sides of the flat solder cups The side is clamped in the limit slot, so that the terminal is completely clamped in the slot, preventing the terminal from falling off due to repeated insertion and extraction.

A WTB connector disclosed by the utility model optimizes the wire end result, uses welding instead of riveting, improves the reliability and stability of the connection, and reduces the difficulty of assembly at the same time.

The above are only preferred embodiments of the present utility model, and are not intended to limit the present utility model in any form. Any simple modifications made to the above embodiments in essence based on the technology of the present utility model, equivalent changes and modifications, all belong to within the scope of utility model technical solutions.
