Description

Shielding case

Technical Field

The application belongs to the technical field of electronic shielding, and particularly relates to a shielding case.

Background

The existing two-piece shield design generally adopts a convex point and hole matching mode. However, the above-mentioned matching method has some technical defects: the bump is required to have very accurate size so as to meet the requirements of sealing and convenient assembly, which requires strict control of mold design and production process; the matching mode of the convex points and the holes can not prevent the cover from expanding and deforming outwards to cause sealing failure; due to the reasons, only manual assembly can be adopted, and the efficiency is not high.

Content of application

To overcome the defects or shortcomings of the prior art, the shielding case has good sealing performance and high assembly efficiency.

In order to solve the technical problem, the application is realized by the following technical scheme:

the utility model provides a shield cover, includes shield cover seat, shield cover lid and conducting resin, wherein, the welding of shield cover seat is on the PCB board, the shield cover lid pass through conducting resin with shield cover seat fixed connection.

As a further improvement, the shielding case seat is further provided with at least one double-folded structure, wherein the double-folded structure is arranged on the side edge of the shielding case seat, and the double-folded structure and the bottom plate of the shielding case seat enclose a first cavity.

As a further improvement, a guide groove is formed on the inner side of the double-folding structure.

As a further improvement, the shielding case seat is also provided with a welding part.

As a further improvement, at least one guide part is arranged on the shield cover, wherein the guide part is arranged on the side edge of the shield cover, and a second cavity is enclosed by the guide part and the bottom plate of the shield cover.

As a further improvement, the guide part is matched with the guide groove.

Compared with the prior art, the method has the following technical effects:

the shielding case can effectively avoid sealing failure caused by outward-expanding deformation; the sealing is more reliable by adding the conductive adhesive for fixation; this application uses the direction recess and the guide part that match the setting, and convenient equipment and mechanized operation have promoted assembly efficiency.

Detailed Description

The conception, specific structure and technical effects of the present application will be further described in conjunction with the accompanying drawings to fully understand the purpose, characteristics and effects of the present application.

As shown in fig. 1 to 6, the shield case of the present embodiment includes a shield case base a, a shield case cover b and a conductive adhesive c, wherein the shield case base a is soldered on a PCB d, and the shield case cover b is fixedly connected to the shield case base a through the conductive adhesive c. In this embodiment, the shield cover seat a is soldered to the PCB d by SMT (Surface Mount Technology, abbreviation of Surface Mount Technology), and after soldering, the shield cover b is assembled to the shield cover seat a, thereby achieving the electromagnetic sealing function.

Further, as shown in fig. 2 and fig. 3, at least one double-folded structure a1 is further disposed on the shield cover seat a, wherein the double-folded structure a1 is disposed at a side of the shield cover seat a, and the double-folded structure a1 and a bottom plate of the shield cover seat a enclose a first cavity a 3. The first cavity a3, the PCB d and the shield cover b form a sealed space to protect the electronic devices in the cavity.

The inner side of the double-folded structure a1 forms a guide groove a2, the guide groove a2 is used with a guide part b1 described below, and the shield cover seat a and the shield cover b are connected by the guide groove a2 and the guide part b1 which are arranged in a matching manner.

The shielding case seat a is further provided with a welding part a4, and the shielding case seat a can be welded on the PCB d through the welding part a 4.

As shown in fig. 4 and 5, at least one guide b1 is disposed on the shield cover b, wherein the guide b1 is disposed at a side of the shield cover b, and the guide b1 and a bottom plate of the shield cover b define a second cavity b 2.

When the shielding cover is applied specifically, the shielding cover seat a is welded on a PCB (printed circuit board) d in an SMT (surface mount technology) mode, and after welding is finished; the conductive adhesive c is pre-adhered to the shield cover b or assembled in a later stage, and the shield cover seat a is assembled on the shield cover b through the matching of the guide groove a2 and the guide part b1, so that the electromagnetic sealing effect is finally realized.

The above embodiments are merely to illustrate the technical solutions of the present application and are not limitative, and the present application is described in detail with reference to preferred embodiments. It will be understood by those skilled in the art that various modifications and equivalent arrangements may be made in the present invention without departing from the spirit and scope of the present invention and shall be covered by the appended claims.
