Abstract
The utility model relates to a changing-over socket for a shielding network interface connector. Aiming at the deficiency of the poor shielding effect of a changing-over socket of an existing plastic part network interface connector, the outer surface of a socket body made of plastic materials is covered with a metal layer for enhancing the electromagnetic shielding effect so that shielding contact can be realized between the socket body and a metal rear cover plate of a machine cabinet to enhance the EMC performance of a complete machine; simultaneously, both side faces of the socket body are respectively provided with a vertically protruding suspension loop, each suspension loop is provided with an installing screw hole, and consequently, the snap-in type installing mode in which the network interface connector changing-over socket is arranged on the rear cover plate is changed into a mode of installation and connection by screw nails so that the installation is firmer, and the reliability is higher.
Description
Technical field
The network interface connector of products such as the utility model relates to and is used for exchanging, Access Network, data communication more particularly, relates to a kind of gauze screen opening connector conversion socket.
Background technology
In products such as exchange, Access Network, data communication, must consider that product meets EMC (Electromagnetic Compatibility, i.e. Electro Magnetic Compatibility) requirement.Its objective is to make electric device or system under common electromagnetic environment condition, neither can be subjected to the influence of periphery electromagnetic environment, also can not cause electromagnetic effect to surrounding environment.In other words, be exactly that it can not cause performance reduction, afunction or damage because of the electromagnetic environment of periphery; Can in surrounding enviroment, not produce excessive electromagnetic energy yet, so that influence the operate as normal of peripheral equipment.
Therefore, the rack of these products has generally all adopted electromagnetic shielding measure, and its principle is to utilize the decay of high-frequency energy in the reflection of shield and the shield to reach the effect of electromagnetic shielding.For the rack of shielding, if there is stube cable to pass rack, even the Kong Zaixiao that opens when transmitting power is big, can influence its EMC performance.
In products such as above-mentioned exchange, Access Network, data communication, its rack generally is designed to the complete machine shielding, is built-in with MODEM (modulator-demodulator).As shown in Figure 1, the telephone line interface of modulator-demodulator 2 need be transferred in the network interface connector conversion socket 4 on rack 1 back shroud by call forwarding line 3 during use, simultaneously COBA (out-of-band communication) network interface on the motherboard also needs to be transferred in the network interface connector conversion socket 4 on rack 1 back shroud by shielding netting wire 5, so just can be implemented in to carry out MODEM under the situation of not dismantling back shroud and surf the Net and the main frame upgrade software.In order to reduce electromagnetic radiation, adopt the call forwarding line 3 that has magnetic bead to link to each other among Fig. 1 with MODEM to device interior.
In order under the situation of not dismantling back shroud, to carry out MODEM online and upgrade software, used the network interface connector conversion socket of buckle mount type in the prior art, its structure is as shown in Figure 2.Figure 3 shows that the generalized section when being installed in this network interface connector conversion socket 4 on the two-sided back shroud 6; Figure 4 shows that the generalized section when being installed in this network interface connector conversion socket 4 on the single face back shroud 7.As can be seen from the figure, the front portion of network interface connector conversion socket 4 is the jacks 41 that cooperate with phono plug, and upper surface is provided with an obliquity prominence platform 42, and the bottom surface is provided with an Elastic buckle 44, and both are parallel to each other; Simultaneously, the distance that respectively is provided with 43, four bayonet locks of two outwardly directed bayonet locks and obliquity prominence platform 42 and Elastic buckle 44 in two sides just in time equals the thickness of snapped-in position on back shroud 6 and 7.On back shroud 6 and 7, offer the installing hole with the identical size of front end of network interface connector conversion socket 4, during installation network interface connector conversion socket 4 is inserted from inside to outside, can be stuck in automatically in back shroud 6 or 7.
Because what adopt is the snap-type mounting means, in order to guarantee the fastness of buckle, the shell of network interface connector conversion socket 4 is plastic parts (for example Ployphenylene Oxide, i.e. a polyphenylene oxide).The shell of this network interface connector conversion socket is non-shielding, therefore can't effectively shield with realization between the metal back cover plate and be connected, although adopt the call forwarding line 3 of shielding netting wire 5 and band magnetic bead, still can't satisfy the EMC performance requirement of product under strict test condition.
The utility model content
The technical problems to be solved in the utility model is, above-mentioned defective at prior art, a kind of gauze screen opening connector conversion socket is provided, contacts the EMC performance of raising complete machine with the good shielding between the metal back cover plate of realizing network interface connector conversion socket and rack.
The technical scheme that its technical problem that solves the utility model adopts is: construct a kind of gauze screen opening connector conversion socket, comprise the socket that the plastics material is made, the two ends of described socket are provided with the jack that can cooperate with the connector changeover plug, be provided with the elastic metallic contact pin in each jack, wherein, the coated metal level that has one deck to be used to improve effectiveness of the outer surface of described socket.
In addition, the socket two sides of the utility model gauze screen opening connector conversion socket respectively are provided with a hangers that vertically stretches out, each hangers is provided with one screw is installed, thereby change the mounting means of network interface connector conversion socket on back shroud into screw by buckle-type ways of connecting is installed, what guaranteed to be connected between described socket and metal back cover plate is reliable and stable.
Compare with existing network interface connector conversion socket, network interface connector conversion socket of the present utility model has following advantage:
(1), by at the coated metal level of its outer surface, can realize that the good shielding between the metal back cover plate of network interface connector conversion socket and rack contacts, reduce to offer the influence of installing hole greatly, the EMC performance of raising complete machine to shielding properties;
(2), change the mounting means of snap-type into hangers and add the screw mounting means, install more firmly, reliability is higher, makes it to satisfy the repeatedly reliability requirement of plug of shielded type cable.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the simplified schematic diagram that the rack of existing product is inner and be connected with motherboard COBA network interface;
Fig. 2 is the structural representation of existing network interface connector conversion socket;
Fig. 3 is the generalized section of the network interface connector conversion socket shown in Fig. 2 when being installed on the two-sided back shroud;
Fig. 4 is the generalized section of the network interface connector conversion socket shown in Fig. 2 when being installed on the single face back shroud;
