Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, in the prior art, a connection manner between a circuit board 1 and a terminal body 2 is that a group of terminal pins are inserted into connection holes, and then the terminal body 2 is slid so that connection ends of another group of terminal pins are connected with welding points on the circuit board 1, and this installation manner increases the trouble of assembly.
As shown in fig. 2-6, a water level sensor terminal structure comprises a circuit board 1 and a terminal body 2, wherein a first welding hole 101 and a second welding hole 102 are formed in the circuit board 1, a first pin 201 and a second pin 202 are fixedly connected to one side of the terminal body 2, and the first pin 201 and the second pin 202 are respectively matched with the first welding hole 101 and the second welding hole 102.
The first pin 201 and the second pin 202 are integrally press-molded on the terminal body 2.
As shown in fig. 5 and 6, an arc groove 211 is formed on one side of the first pin 201, and through the arrangement of the arc groove 211, solder can enter the first soldering hole 101, so as to increase the stability of contact soldering between the solder and the circuit board 1, and meanwhile, an arc protrusion 212 is arranged on one side of the first pin 201 far from the arc groove 211, and through the arrangement of the arc protrusion 212, the thickness of the first pin 201 is increased, so that the strength of the first pin 201 is improved, and the first pin 201 is prevented from deforming.
As shown in fig. 5 and 6, the two sides of the first pin 201 and the second pin 202 are trapezoidal 213, and by the arrangement of the trapezoidal 213, the widths of the first pin 201 and the second pin 202 are smaller than the inner diameters of the first welding hole 101 and the second welding hole 102, so that the first pin 201 and the second pin 202 are conveniently inserted into the first welding hole 101 and the second welding hole 102 respectively, and the connection part of the first pin 201 and the terminal body 2 is in interference fit with the first welding hole 101, so that after the first pin 201 is inserted into the first welding hole 101, the root part of the first pin 201 can be limited and fixed with the first welding hole 101, and the first pin 201 is prevented from swinging in the first welding hole 101, so that welding is convenient.
As shown in fig. 5 and 6, the step 203 is disposed in the middle of the terminal body 2, and the step 203 is attached to the side wall of the circuit board 1, so as to limit the terminal body 2 and improve the stability of the terminal body 2 after welding.
