Description

The RCA connector
[technical field]
The utility model relates to a kind of electric power connector, relates in particular to a kind ofly to have single grounding path and big spacing is grabbed the plate hook arm, meets the RCA connector of European standard.
[background technology]
Because the digital household appliances product is flourish, many products must form a kind of novel combined type information household appliances series products with the function of info class product in conjunction with household appliances.But contrast the requirement of original electromagnetic compatibility standard, the limit value that the electromagnetism wave amplitude of simple household appliances product is penetrated is wanted loose 10dB with respect to the limit value of info class product.And according to existing electromagnetic compatibility standard, combined type information household appliances series products should meet the limit value requirement that the electromagnetism wave amplitude of household appliances product and info class product is penetrated simultaneously, could freely peddle on market by the authentication of relevant electromagnetic compatibility.
(RCA is Radio Corporation ofAmerica, the Radio Corporation of America owing to the RCA connector; The RCA connector is that the wiring terminal of the lead wiring of the non-equilibrium or coaxial-type of by RCA exploitation connects standard, be used for most stereo equipments and video tape recorder, Voice ﹠ Video I/O) be applied to the port of audio-visual I/O more, and the analog signal of video and audio frequency is very easy to be subjected to interference, the coupling of digital noise, the problem that causes more serious electromagnetism wave amplitude to penetrate, therefore, present RCA connector generally all has the design of EMI shielding construction.But because a RCA connector has a plurality of butt joint posts usually, each butt joint post all will have metal shell that EMI is provided shielding, and each metal shell all will keep the grounding path conducting with equipment, otherwise shield effectiveness is significantly reduced, even do not play any shielding action.Therefore, correspondingly to be provided with the ground path hole of same quantity on the circuit board, fix the earth terminal pin of these metal shells with welding.Yet for the multilayer line circuit board of present main flow, the increase of pore quantity can increase the difficulty of circuit board line layout-design inevitably.In addition, be subjected to the influence of plug power and cause connector to take place loosening even problem such as topple, extend a pair of hook arm usually in the bottom of RCA connector downwards, to match buckle to strengthen its grabbing plate force degree with fixing hole on the circuit board for fear of the process of patching.Yet, because being direct bottoms from the connector insulating body, these hook arms extend to form downwards, distance is very near between the earth terminal pin of the terminal supportor of hook arm and connector and metal shell, correspondingly, terminal hole and the distance between the fixing hole corresponding on the circuit board are also very near, and this situation has increased the puzzlement of circuit board line layout-design process too.And, phase mutual edge distance between the hook arm of both sides is often less than the length of connector body own, this situation also causes plug to advocate to concentrate on the earth terminal pin of connector below, the scolder between earth terminal pin and the circuit board that causes easily of a specified duration ftractures, thereby cause the earth terminal pin loosening and break away from, so that situation such as take place that connector topples with circuit board.
[utility model content]
The purpose of this utility model is to provide a kind of RCA connector, it has single grounding path and big spacing is grabbed the plate hook arm, can reduce respective terminal pin connecting hole quantity on the circuit board, increase the distance between hook arm fixing hole and the connecting hole, reduce the puzzlement of circuit board line layout-design, and the grabbing plate force degree of enhancing connector, prevent that connector from taking place to become flexible and topple because of excessive plug.
For achieving the above object, the utility model adopts following technical scheme: a kind of RCA connector, comprise insulating body, conducting terminal and shielding casing, this insulating body has a main part, the front surface of main part is provided with several butt joint posts, and each butt joint post middle part is equipped with the jointing holes that connects to insulating body inside.Shielding casing is the open cylindrical shell of hollow and top, is wrapped in butt joint post outside so that EMI to be provided shielding.Conducting terminal comprises some signal terminals and an earth terminal, and signal terminal is arranged in the jointing holes of insulating body, earth terminal then be fixed on the insulating body and be coated on the shielding casing that docks the post outside and electrically conduct.
According to the RCA connector that the purpose of this utility model provided, wherein outwards respectively protrude and be provided with a hook arm from the left and right side of insulating body main part, each hook arm all has the connecting portion that links to each other with the side of main part, be parallel to left and right side from connecting portion and face down and extend a segment length and form an extension, and the end of the extension of and arranged on left and right sides is respectively to main part direction projection and form a hook portion a little.
According to the RCA connector that the purpose of this utility model provided, the distance between the medial flange of insulating body main part and arranged on left and right sides hook portion wherein is greater than the distance between the left and right side of main part.
Compare with existing RCA connector, RCA connector provided by the utility model meets European standard, it can realize the conducting of the grounding path of each shielding casing by an earth terminal, avoided that each shielding casing all will design an earth terminal pin in the existing structure, so that increased pore quantity on the circuit board and the puzzlement of the circuit board layouts design aspect that causes.And the utility model is by the bigger hook arm configuration of a pair of spacing, more powerful grabbing plate force can be provided and make the RCA connector can more firmly be fixed in circuit board, avoids causing the RCA connector loosening even topple because of the bigger plug power of grafting process.
