Example (b):

referring to fig. 1 and 2, for the utility model discloses a multi-functional compound connector, including male connector 2 and with male connector 2 complex female connector 1, female connector 1 is installed in inclosed metal frame 11, and male connector 2 is mutually joined in marriage with female connector 1 through the window of reserving on the metal frame 11. The male connector 2 comprises a metal shell 5 and a male housing 3 screwed with the metal shell 5, wherein a plurality of connectors are arranged on the side surface of the male housing 3, and the connectors can be a combination of radio frequency 31, high frequency 32, power supply 33, USB, HDMI, network interface connector and the like. In this embodiment, the side of the male housing 3 is provided with a radio frequency 31, a high frequency 32, and a power supply 33. Since the male housing 3 integrates the power supply 33, the high frequency 32 and the radio frequency 31, more product functions are realized in a limited space. The relative both sides face of public first casing 3 all is provided with cross-section semicircular in shape guide post 34, all sets up on the relative both sides face of female seat connector 1 and supplies guide post 34 male guide way 12, and when public female was mutual, the guide post 34 of public first casing 3 contacted with female seat connector 1 side recessed guide way 12 earlier to play the effect of direction.

Referring to fig. 7 and 8, an elastic buckle 321 is integrally formed on the top surface of the high frequency 32 connector, and a limiting opening 36 matched with the elastic buckle 321 is formed on the male housing 3. When the high-frequency 32 connector is assembled with the male housing 3, the elastic buckle 321 on the high-frequency 32 connector is matched with the limit port 36 on the male housing 3 to play a role in limiting and fixing.

Referring to fig. 1 and 2, a mounting hole 51 is formed in a side surface of a front end of the metal housing 5, and the cable 4 connected to the radio frequency 31, the high frequency 32, and the power supply 33 is inserted into the mounting hole 51. The cable 4 is inserted into the mounting hole 51, then passes through the rectangular through hole at the rear end of the metal shell 5, is assembled with the connectors of the power supply 33, the high frequency 32 and the radio frequency 31, is loaded into the male housing 3, pushes the assembled male housing 3 into the metal shell 5, and then fixes the male housing 3 and the metal shell 5 by the screw 35. Because the unshielded part of the cable 4 is wrapped by the metal shell 5, the rear end of the male shell 3 is completely shielded, and the electromagnetic radiation shielding capability of the multifunctional composite connector can be improved, so that the anti-electromagnetic interference capability of the connector is improved.

Referring to fig. 2 and 3, in order to further improve the electromagnetic radiation shielding capability and the electromagnetic interference resistance of the connector, a metal ring 6 is sleeved on one end of the cable 4 close to the male housing 3, that is, the exposed shielding layer at the peeling position of the cable 4 is fixed by the metal ring 6. One end of the metal ring 6 close to the metal shell 5 is coaxially connected with a soft conducting ring 7, the soft conducting ring 7 abuts against the inner side wall of the mounting hole 51 close to one end of the male shell 3, and the soft conducting ring 7 enables the mounting hole 51 at the rear end of the metal shell 5 and the metal ring 6 to form a shielding space without a dead angle in 360 degrees after being assembled.

Referring to fig. 2 and 4, a seal ring 8 with a square cross section is connected to the end surface of the metal shell 5 close to the male housing 3, and a square groove 52 for the seal ring 8 to be inserted is formed in the end surface of the metal shell 5. The metal shell 5 and the metal frame 11 are fixed together by four screws and a sealing ring 8. The seal ring 8 comprises an inner ring 81 and an outer ring 82 coated outside the inner ring 81, the inner ring 81 is made of soft conductive material, the outer ring 82 is made of waterproof material, and then the male connector 2 is fixed with the metal machine frame 11 through screws to form a completely shielded and waterproof structure.

Referring to fig. 5 and 6, in order to improve the connection tightness between the cable 4 and the male housing 3, a fixing component 9 for fixing the cable 4 and the metal shell 5 is disposed at an end of the cable 4 away from the male housing 3. In this embodiment, the fixing assembly 9 includes an O-ring 92, a clamping coil 91, a soft gasket 93 and a sealing nut 94 sequentially sleeved on the cable 4 along the length direction of the cable 4, the sealing nut 94 is located at an end far away from the mounting hole 51, and the soft gasket 93 is wrapped on the cable 4. The boss of the clamp coil 91 is fitted into the mounting hole 51 at the end of the metal shell 5, and the clamp coil 91 itself does not rotate when the seal nut 94 is tightened. Meanwhile, the O-ring 92 plays a role of sealing after the clip coil 91 is fitted into the male housing 3. On the other hand, when the sealing nut 94 is tightened, the claw structure on the clamping coil 91 contracts inward, and the soft gasket 93 is clamped and the cable 4 is clamped, thereby further achieving a sealing effect. The fixing assembly 9 enables a sealed waterproof space to be formed inside the metal shell 5, and waterproof performance of the product is improved. Other fastening means, such as snap-fit, may be used for the fixing assembly 9.

The implementation principle of the embodiment is as follows: because the unshielded part of the cable 4 is wrapped by the metal shell 5, the totally enclosed metal shell 5 can achieve the shielding effect on the absorption loss, the interface reflection loss and the metal internal reflection loss of incident electromagnetic waves, and can improve the electromagnetic radiation shielding capability of the multifunctional composite connector, thereby improving the anti-electromagnetic interference capability of the connector.

Meanwhile, the exposed shielding layer at the stripping position of the cable 4 is fixed by the metal ring 6, and then the mounting hole 51 at the rear end of the metal shell 5 and the metal ring 6 are assembled to form a shielding space with 360 degrees and no dead angle by using the soft conducting ring 7, so that the anti-electromagnetic interference capability of the product is further improved.

The inner ring 81 of the sealing ring 8 plays a role of shielding and sealing, and the outer ring 82 plays a role of insulating and waterproof, so that the sealing ring 8 plays dual roles of waterproof and sealing.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
