目前，车载充电器广泛应用于各种汽车上，能方便司机或乘坐车辆的人能及时为手机、数码相机、MP3、MP4等数码产品充电，如开车外出旅行或长时间在车上的司机是必不可少的。现有的车载充电器的负极外罩通过导线与PCB板焊接，再将带有弹力的垫块焊接与负极外罩内，再通过折弯负极外罩上的片脚来固定装配，组装繁琐，当内部PCB板的线路故障时，检修困难。 At present, car chargers are widely used in various cars, which can facilitate drivers or people in vehicles to charge mobile phones, digital cameras, MP3, MP4 and other digital products in time, such as drivers who travel by car or stay in the car for a long time. necessary. The negative electrode cover of the existing car charger is welded to the PCB board through the wire, and then the elastic pad is welded to the negative electrode cover, and then fixed and assembled by bending the legs on the negative electrode cover. The assembly is cumbersome. When the internal PCB When the circuit of the board is faulty, it is difficult to overhaul.
实用新型内容 Utility model content
本实用新型的目的是针对现有技术的上述缺陷，提供一种装配简单，检修方便的车载充电器负极外壳结构。 The purpose of this utility model is to provide a vehicle-mounted charger negative shell structure with simple assembly and convenient maintenance for the above-mentioned defects of the prior art.
为解决现有技术的上述缺陷，本实用新型要解决的技术方案是：一种车载充电器负极外壳结构，包括一壳体，壳体的一端设有供电器插接的接口件，所述壳体上间隔设有多个插装负极外罩的凹槽，所述凹槽的内壁两侧分别设有一凸块，所述凹槽底部设有一通孔。 In order to solve the above-mentioned defects of the prior art, the technical solution to be solved by the utility model is: a negative shell structure of a vehicle charger, including a shell, one end of the shell is provided with an interface piece for plugging in a power supply, and the shell The body is provided with a plurality of grooves for inserting the negative electrode cover at intervals, a protrusion is respectively arranged on both sides of the inner wall of the groove, and a through hole is arranged at the bottom of the groove.
作为本实用新型车载充电器负极外壳结构的一种改进，所述负极外罩的横切面呈几字型。呈几字型的负极外罩沿通孔插入，插入后由于受负极弹簧的弹力作用使呈几字型的负极外罩张开，勾住通孔内壁的凸块。 As an improvement of the structure of the negative electrode shell of the vehicle charger of the present invention, the cross-section of the negative electrode shell is in the shape of a few characters. The negative electrode cover in the shape of a few characters is inserted along the through hole. After being inserted, the negative electrode cover in the shape of a few characters is opened due to the elastic force of the negative electrode spring, and hooks the protrusion on the inner wall of the through hole.
