Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The various embodiments and features of the embodiments described below may be combined with one another without conflict.

Referring to fig. 1-3, an embodiment of the present utility model provides an EMC cover connector, which includes a cover body 1 and a connector, wherein the connector comprises a connector base 2 and at least one signal conductor 3 accommodated in the connector base 2, the outer surface of the connector base 2 penetrates through the sidewall of the cover body 1, and the connector base 2 has an external connection end for connecting with an external signal conductor 3.

In communication devices, a radio frequency connection is typically required between the cavity filter and the printed circuit board. In the prior art, radio frequency connection is performed through three separate connector sets (plug connectors formed by a male connector, a female connector and a central connecting rod), so that the male connector and the female connector are required to be fixed at proper positions at first during connection, and then are connected during installation. Since there is also an EMC cover plate between the cavity filter and the PCB, it will become more difficult to mount the butt joint male and female sockets, and the shielding effect of the EMC cover plate needs to be taken into account, so that the male and female sockets cannot form voids in the EMC cover plate when in a connected state. The method for performing radio frequency connection by using the three-piece connection of the connector comprises the steps of arranging a tap post at an output (or input) tap of the cavity filter, arranging a threaded hole on the tap post, and fastening the output (or input) end of the printed circuit board and the tap post together in a screw fastening mode to form radio frequency connection. Because it requires a threaded hole in the tap post, a tap post of larger diameter is required and therefore occupies a larger filter cavity space. On the other hand, in the prior art, the output (or input) tap of the cavity filter is directly welded to the printed PCB board, so that the PCB board is inconvenient to disassemble if necessary.

In the above embodiment, the connector body is arranged on the cover plate body 1 of the EMC cover plate in a penetrating manner through the connector transmission theory, that is to say, the shielding part in the three-piece connector in the prior art is processed on the cover plate body 1, and the shielding part is directly shielded through the cover plate body 1, so that the shielding device can be effectively used for shielding the path from the PCB board to the cavity filter. Wherein, as shown in fig. 1, when connecting the PCB board and the cavity filter, one end of the connector base 2 is used to connect with the connection end of the PCB board, and then one end of the signal conductor 3 is connected with the corresponding signal conductor 3 arranged on the PCB board, and the other end of the signal conductor 3 passes through the connector base 2 to connect with the corresponding signal conductor 3 on the output (or input) tap of the cavity filter. Therefore, when the connector is installed, the two ends of the signal conductor 3 are connected with the PCB and the cavity filter respectively, so that the radio frequency connection of the PCB and the cavity filter can be realized, the independent male connector, the female connector and the central connecting rod are not required to be utilized for radio frequency connection, and the installation time of the connector can be saved. In addition, a tap column with a larger size is not required to be arranged at an output (or input) tap of the cavity filter during connection, so that the cavity space of the cavity filter can be saved. Illustratively, if as shown in fig. 1, one end of the connector base 2 may exceed the cover plate body 1, and the other end is substantially flush with the lower end surface of the cover plate body 1, so that the cavity space of the cavity filter may be further saved, and the end of the connector base 2 protruding out of the cover plate body 1 may be conveniently plugged with the PCB board, so that the installation and the disassembly of the PCB board circuit are facilitated.

Specifically, when the two ends of the connector base 2 are respectively connected with the PCB board and the cavity filter, the connector base is in a plugging form, so that the connection part may be easily interfered by the outside, which is not beneficial to signal shielding. Therefore, in some embodiments of the present utility model, the perimeter of one end of the connector base 2 is used to connect with the PCB board through conductive adhesive, and the perimeter of the other end is used to connect with the cavity filter through conductive adhesive, so as to further improve the shielding effect of the path from the PCB board to the cavity filter.

Referring to fig. 1 to 3, considering that the connector base 2 is exposed to the outside, it may be affected by various external influences, so that the signal conductors 3 accommodated therein are easily damaged when the connector base 2 is damaged, thereby affecting the effectiveness of the radio frequency connection. In some embodiments of the utility model, the joint base 2 is provided with a joint protector 4 in the circumferential direction. Namely, by arranging the joint protector 4 in the circumferential direction of the joint base body 2, the connector base body 2 can be protected from being greatly influenced by the outside, so that the service life of the connector joint can be effectively ensured.

Referring to fig. 1-3, in some embodiments of the present utility model, a sealing ring 5 is disposed at one end of the joint protection member 4.

In the above embodiment, by arranging the sealing ring 5 at the end of the joint protection member 4, the tightness of the connection position can be further improved, so that foreign matters such as dust outside can be prevented from contacting the signal conductor 3 through the gap of the connection position, and the signal transmission problem caused by particles in dust accumulation during radio frequency connection can be reduced.

Referring to fig. 1-3, in some embodiments of the present utility model, a signal insulator 6 is disposed between the signal conductor 3 and the connector base 2.

In the above embodiment, the function of the signal insulator 6 is to ensure that no optical signal is transmitted between the optical conductor 3 and the connector base 2 when the signal conductor 3 is an optical conductor, and no electrical signal is transmitted between the electrical conductor and the connector base 2 when the signal conductor 3 is an electrical conductor, so as to ensure stable and effective signal transmission.

Referring to fig. 1-3, in some embodiments of the present utility model, the signal conductor 3 is of a type of optical conductor or electrical conductor, wherein the external signal conductor 3 and the signal conductor 3 received in the connector body 2 are of the same type. In this case, since the types of the external signal conductors 3 which are connected to each other and the signal conductors 3 which are accommodated in the connector base body 2 are identical, it is possible to ensure stable and effective connection, and to avoid quality problems in signal transmission due to the type distinction.

Of course, in some embodiments of the present utility model, the signal conductors 3 accommodated in the connector body 2 are all optical conductors, or the signal conductors 3 accommodated in the connector body 2 are all electrical conductors, or a part of the signal conductors 3 accommodated in the connector body 2 are optical conductors, and the other part is an electrical conductor. Therefore, one EMC cover plate connector can be connected in various modes by utilizing different signal conductors 3 according to the requirements, and the connection compatibility of the EMC cover plate connector is improved.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
