Abstract

The utility model discloses a pin installing structure of a switch power supply adapter. The switch power supply adapter comprises an upper cover, pins and small conducting wires. The pins are in spot welding and connection with the small conducting wires and then are injection molded into a pin assembly, a boss is formed inside the upper cover, and the pin assembly is welded on the boss. Compared with the conventional pins, the pin installing structure of the switch power supply adapter of the utility model avoids affecting the appearance of the whole adapter, and also has the characteristics of reducing cost substantially and being good in product quality and stability.

Description

A kind of switch power source adapter pin mounting structure

Technical field

The utility model relates to the switch power source adapter field, relates in particular a kind of switch power source adapter pin mounting structure.

Background technology

As shown in Figure 1 to Figure 3, it is the step schematic diagram of traditional switch power supply adaptor 2 when pin 21 is installed.As shown in Figure 1, pin 21 and the little wire 22 use flatirons of independent injection mo(u)lding are added tin welding together, the pin assembly after then processing is locked on lower cover 24 with screw 23; As shown in Figure 2, little wire 22 is weldingly connected with circuit board 26 to be fitted together lower cover 24 and shell 25 again, to form structure shown in Figure 3, has namely formed a complete switch power source adapter 2.

But there is following defective at least in above-mentioned conventional art when pin 21 is installed:

One, when being welded on little wire 22 on pin 21, due to the impact of welding temperature, the plastic cement on pin 21 easily overflows, and then affects the outward appearance of whole switch power source adapter 2;

Two, due to the little wire 22 of needs manual welding and pin 21 use screws 23 need to be locked on lower cover 24, so it needs the Master Cost of screw 23 and higher processing charges, and quality stability is relatively poor.

In view of this, the inventor has this case to produce for the defects further investigation of existing switch power source adapter 2 then.

The utility model content

The purpose of this utility model is to provide a kind of switch power source adapter pin mounting structure, to solve the prior art easily whole switch power source adapter outward appearance of impact and the higher problem of expense.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of switch power source adapter pin mounting structure, wherein, this switch power source adapter comprises upper cover, pin and little wire, injection molded pin assembly after this pin is connected with little wire spot welding, this upper cover inside is formed with boss, and this pin components welding is on boss.

Further, adopt ultrasonic bonding to be connected between this pin assembly and boss.

After adopting said structure, a kind of switch power source adapter mounting structure that the utility model relates to, it has following beneficial effect at least:

One, with respect to traditional pin, it does not need to expose many positions and welds little wire, so can reduce by 20% pin material, reduces costs, and the operation of spot welding simultaneously and ultrasonic bonding is also saved man-hour and improved quality;

Two, owing to being first to weld rear injection moulding to form the pin assembly between this pin and little wire, so avoiding welding temperature to cause plastic cement to overflow and then affect the problem of outward appearance;

Three, the utility model need not to adopt screw to connect, thereby has saved Master Cost and processing charges, and has the good effect of quality stability.

Embodiment

In order further to explain the technical solution of the utility model, the utility model is elaborated below by specific embodiment.

As extremely shown in Figure 6 in Fig. 4, a kind of switch power source adapter 1 that the utility model relates to, it is the same with prior art, also comprises shell 11, upper cover 12, pin 13, little wire 14 and circuit board 15.Main improvements of the present utility model are the improvement to pin 13 mounting structures, specifically:

Injection molded pin assembly after this pin 13 is connected with little wire 14 spot welding, this upper cover 12 inside are formed with boss 121, and this pin components welding is on boss 121.Preferably, adopt ultrasonic bonding to be connected between this pin assembly and boss 121.

Like this, the utility model has following beneficial effect at least:

One, with respect to traditional pin 13, it does not need to expose many positions and welds little wire 14, so can reduce by 20% pin 13 materials, reduces costs, and the operation of spot welding simultaneously and ultrasonic bonding is also saved man-hour and improved quality;

Two, owing to being first to weld rear injection moulding to form the pin assembly between this pin 13 and little wire 14, so avoiding welding temperature to cause plastic cement to overflow and then affect the problem of outward appearance;

Three, the utility model need not to adopt screw to connect, thereby has saved Master Cost and processing charges, and has the good effect of quality stability.

Above-described embodiment and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
