Description

A combined color tube TV casing

technical field

The utility model relates to a color tube (CRT) TV set, in particular to a combined color tube TV shell with good versatility.

Background technique

At present, the structure and outsourcing of the color picture tube (CRT) installed in the TV set are integrally formed by adopting the surface molding of the outsourcing and the structure for installing the CRT. As shown in FIG. 1 , the CRT of the TV is generally installed on the front case 01 , and cooperates with the rear case 02 to form a complete TV outsourcing structure. For color TVs of different specifications, it is necessary to configure outsourcing of different specifications, that is, molds of various specifications are required. The front case of the TV is the main outsourcing shape of the TV, and it bears the gravity of the TV CRT and the installation of the electronic movement. If you want to change the shape of the front case, you must consider installing the structural part of the CRT, the installation part of the electronic movement and the speaker part of the installation structure. That is to say, if you want to change the complete appearance of a product, you have to change the product structure. As a result, the structure constrains the appearance, and the appearance restricts the structure. There are following obvious defects in prior art:

1. The outsourced modeling cycle for updating a product is long, and the structure of installing CRT and movement must be modified accordingly;

2. The cost of developing products (molds) is high;

3. The process debugging of the mold is complicated during the production process, and there are many surface defects on the product, which are difficult to solve. Today's electronic products, especially TV products, are being updated with each passing day. The market competition is fierce, and the operation has entered the era of meager profits. A TV product with an outsourced shape was eliminated when the sales volume was roughly 10,000 to 50,000 units. In this economic environment, if you want to have a place in the TV field, you must compete not only in terms of time, but more importantly, in terms of product design costs. Therefore, the development of a TV outsourcing with a simple main structure and a series structure can win the competition in terms of time and cost.

Utility model content

The utility model aims to solve the technical problems of long product development cycle and high product development cost caused by the poor universality of the existing color tube TV shell, and provides a combined color tube that is made of general molds and adapts to various specifications of CRT, panels, and rear shells.
