Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an electromagnetic shielding connector in which a metal cover is attached around an electrically insulating casing containing connection terminals.

[Prior Art] Various types of electromagnetic shielding connectors have been known in the past, but they generally have complex structures and are difficult to assemble. For example, attaching a metal cover to a synthetic resin casing requires cumbersome screws and crimping.
The disadvantage is that the cost is also high. In addition, many have insufficient electromagnetic shielding effects, and very few have complete electromagnetic shielding.

[Object of the invention] An object of the invention is to provide an electromagnetic shielding connector that has a high-performance electromagnetic shielding effect and can be easily assembled.

[Summary of the invention] The gist of the invention to achieve the above objectives is as follows:
In a connector in which two metal covers are stacked and adhered around a housing that accommodates connection terminals and has electrical insulation properties, the metal covers include a first cover having a substantially U-shaped cross section, and a first cover having a substantially U-shaped cross section; a second cover;
Both side surfaces and the back surface of the housing are covered with the first cover, and both side surfaces, top surface, bottom surface, and a portion of the back surface of the combined body in which the housing and the first cover are locked are covered with the second cover. This is an electromagnetic shielding connector characterized by being covered and locked with a cover.

[Embodiments of the invention] The invention will be described in detail based on illustrated embodiments.

1, 2, and 3 respectively show a front view, a sectional view, and a rear view of the electromagnetic shielding connector according to the present embodiment, and show the periphery of the housing 1 made of synthetic resin having electrical insulation properties. First and second covers 2 and 3 made of metal plates such as copper, brass, and steel are sequentially attached to the top. A large number of insertion holes 4 are provided in the back of the housing 1, and connecting terminals 5 bent in an L shape are inserted into these insertion holes 4 from the rear side of the housing 1, not shown. It is fixed to the housing 1 by a locking means. These connection terminals 5 also pass through holes 6 of the first cover 2 covering the rear side of the housing 1, and there is a gap between these holes 6 and the connection terminals 5. A cylindrical insulating member 7 made of ceramics is inserted for insulating.

To explain the structure of this embodiment in more detail, this electromagnetic shielding connector mainly includes a housing 1 shown in FIGS.
It consists of a cover 2, a square tubular second cover 3,
The housing 1 has a space 8 in which the connection end of the connection terminal 5 is exposed, and grooves 10 for locking the first cover 2 are provided on both sides 9 of the space 8 .
Furthermore, a locking part 11 including a locking mechanism for fitting and locking a mating male connector is provided at the upper part of the housing 1.

A first cover 2 covers both side walls and the back surface of the housing 1. The first cover 2 is provided with claws 12 protruding inwardly on both sides to engage with the grooves 10 of the housing 1, and locking holes 13 for engaging with the second cover 3. is provided. Further, on the rear surface 14 of the first cover 2, a large number of holes 15 for attaching the insulating member 7 interposed between the connection terminal 5 and the insertion hole 4 of the housing 1 are arranged regularly. It is perforated. Furthermore, protruding pieces 16 extending downward are provided at the tips of both side surfaces to be inserted into a board or the like to stabilize the posture, or to be used as a grounding terminal.

Furthermore, the second cover 3 is for covering part of both side walls, the top surface, the bottom surface, and the back surface of the housing 1, and has an inner side for engaging with the locking hole 13 of the first cover 2. A bulging convex portion 17 is formed, and a bulging portion 18 bulging upward is provided to cover the locking portion 11 of the housing 1. Also, there is a screw hole 1 for fixing this electromagnetic shielding connector to a panel etc.
9 is extended laterally from both sides.

Therefore, in order to assemble this electromagnetic shielding connector, first insert the second cover 3 loaded with the insulating member 7 into the hole 15 from the rear side of the housing 1,
The claws 12 and the grooves 10 of the casing 1 are used to assemble the two so that they cannot be easily separated, and then the second cover 3 is pushed into the combined body from the rear side of the casing 1, and its protrusion 17 is removed. Locking hole 1 of first cover 2
3, these three members 1,
2 and 3 become one. Then, the connecting terminal 5 is fixed to the housing 1 by first passing the insulating member 7 attached to the first cover 2 from the rear side of the housing 1 and then inserting it through the insertion hole 4 of the housing 1. do.

The electromagnetic shielding connector assembled in this way is
They cannot be separated from each other unless there is a particular intention to disassemble them, and the electric wires are connected to the outward ends of the connection terminals 5,
It can function by coupling with a mating male connector. Further, regarding electromagnetic shielding, the first and second metal covers completely cover the housing 1 except for the front portion where the mating connector is fitted, so that the effect is perfect.

Although the embodiment has been described with respect to the female connector, the same applies to the male connector as well.
The cover 2 and the second cover 3 can be configured as main parts.

[Effects of the Invention] As explained above, the electromagnetic shielding connector according to the present invention can be easily assembled by covering the housing with two metal covers, and can provide effective electromagnetic shielding.
