Abstract

The utility model discloses a section bar box, which comprises a casing and an end cap, wherein, a guiding installation groove is arranged inside the casing for PCB lead-in and installation; the end cap is arranged at the end part of the casing for fixing the PCB. The utility model provides a novel structural form of section bar box and installs the PCB through the guiding groove designed inside the section bar; compared with prior art, the box avoids using of bolt in PCB installation and has simple structural form with perfect electric continuity of the whole box body, thereby guaranteeing well the EMC performance of the box body; due to the main body of the box body adopting section bar form, cost can be reduced greatly under the condition of mass production; in addition, under the condition of similar size, the box body possesses perfect versatility.

Description

A kind of section bar box body

Technical field

The utility model relates to a kind of section bar box body in the communication electronic applications.

Background technology

The small-sized box body equipment of communication at present, electronic product is a lot, generally adopts the form of plastic cement, panel beating, section bar etc.From box body structure, the manufacturing procedure of panel beating box body is more, and when producing in enormous quantities, cost is also higher; From PCB (printed circuit board) installation form, plastic cement, that the panel beating box body need use screw to carry out is fastening, and efficiency of assembling is low; In addition, the plastic cement box body is owing to the characteristic of its this life of material, and its heat radiation and EMC (electromagnetic compatibility) are difficult to guarantee.

Therefore at the communication electronic applications, press for a kind of heat radiation and EMC function admirable, cost is low, production efficiency is high novel box body structure.

The utility model content

The problem that the utility model solved provides the communication that a kind of PCB installation form is simple, cost is low, the section bar box body of electronic product.

Technical scheme

The technical scheme that the utility model adopted is: the section bar box body comprises housing, end cap, has the guiding mounting groove in the described housing so that pcb board import to be installed, and described end cap is installed on shell end and in order to fixing PCB.

Described end cap comprises protecgulum, bonnet, and described protecgulum, bonnet are installed on the housing rear and front end in order to fixing PCB with screw.

In order to reach effect attractive in appearance, therefore mill out step with the mode of milling so that protecgulum, bonnet are installed in the housing at the two ends of housing.

Simple in order to install, be provided with screw at the housing two ends, protecgulum, bonnet are installed on the housing rear and front end by screw.

For the ease of adding product mark, also be provided with flat-bottom slot at the hull outside face.

The beneficial effects of the utility model are: the utility model provides a kind of version of new section bar box body, by the gathering sill that on section bar inside, designs PCB is installed, compared with prior art, avoided the use screw that PCB is installed, version is simple, and whole box body electrical continuity is fine, has guaranteed the EMC performance of box body well.Because what the main body of box body adopted is profile form, under large batch of situation, can reduce cost greatly.At the close situation of size, the versatility of box body is fine.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:

Fig. 1 is a section bar housing schematic perspective view of the present utility model;

Fig. 2 is a section bar housing schematic cross-section of the present utility model;

Fig. 3 is a section bar box body blast structure chart of the present utility model;

Fig. 4 is a section bar box body assembling schematic diagram of the present utility model.

Embodiment

Section bar box body in the utility model specific embodiment comprises with the lower part: housing 01, protecgulum 02, bonnet 03.

As Fig. 1, Fig. 2, shown in Figure 3, section bar housing 01 in housing 01 inside, has guiding mounting groove 12 so that the importing of PCB 04 is installed as main body is installed in position; Consider constructional simplicity, the installation of protecgulum 02, bonnet 03 adopts sunk screw 05 directly to be fastened on the rear and front end of housing 01, so be provided with screw 11 in the centre position, both sides at housing 01 two ends; In order to reach effect attractive in appearance, need make protecgulum 02, bonnet 03 be installed on the inside of housing 01, therefore mill out the step of certain depth with the mode of milling at the two ends of housing 01, form a rectangular profile.In addition, in order to add the sign of product, also on housing 01 lateral surface, be provided with flat-bottom slot 13.

The installation process of section bar box body: (1) is inserted into the position with PCB 04 along the guiding mounting groove 12 of section bar housing 01; (2) protecgulum 02 is packed into housing 1 front end, and fastening with sunk screw 05; (3) bonnet 03 is packed into housing 01 rear end, and fastening with sunk screw 05.Above installation form has guaranteed the electrical continuity of box body well, and therefore, EMC is functional, the assembling finish after as shown in Figure 4.
