Description
Technical field
The utility model relates to a kind of connector of jamproof electronic device field, relates in particular to a kind of filter connector.
Background technology
Because it is more and more higher that modern electronic equipment requires Electro Magnetic Compatibility, shielding, filtering, ground connection are to solve electronic equipment to exempt electromagnetic interference and disturb extraneous three magic weapons.So at modern electronic equipment, especially in the Military Electronic Equipment, all be connected with external system by means of the filter connector that in having the connector of function of shielding, installs the filter element formation additional, shielding, filtering, three kinds of methods of ground connection are used simultaneously, avoid interference by signal transmssion line or power transit line and enter or leak out the equipment that has shielded, to obtain optimum efficiency.
At present, filter connector with good filter effect, electric capacity, inductance to be welded consist of the filtering contact assembly at contact, again a plurality of filtering contact assemblies are penetrated that welding consists of filtering unit in the hole of metal ground plate, again filtering unit is contained in the metal shell, the metal ground plate of filtering unit is connected with metal shell by welding or conductive adhesive, thereby forms complete filter circuit.
The filter connector of this structure will pass through multiple welding, and following shortcoming is arranged in welding process: operating procedure is complicated, needs use specific purpose tool, and accurately grasp weld time and temperature, also requires very high to the selection of scolder; Moreover the electric capacity material be the pottery, the rigidity contacts such as welding can cause electric capacity to be mechanically damaged and lose efficacy; And heating repeatedly, cooling can cause that the variation of pottery be full of cracks and capacitor's capacity causes product failure or consistency poor; Welding consists of filtering unit in the hole of metal ground plate and a plurality of filtering contact assemblies are penetrated, if going wrong, a filtering contact assembly will cause whole filtering unit to lose efficacy, rate of finished products is low, thereby has limited the development of filtering technique and applying of filter connector.
In order to overcome above shortcoming, filter connector of the present utility model has adopted exempts from welding structure, prevents that thermal shock from producing stress and damaging filter capacitor on the filtering contact assembly; Adopt and entirely to flexibly connect technology and place rubber blanket and avoid electric capacity to be subject to the rigidity extruding and damage; Adopt the embedding fluid sealant to avoid moisture to invade and harass.
Summary of the invention
The purpose of this utility model is to provide a kind of filter connector to satisfy the requirement of equipment interface place electromagnetic compatibility, employing is packed in metal connector shell with the filtering contact assembly of filter capacitor, the flexible termination of filtering contact assembly and shell makes the High-frequency Interference that is coupled on the contact be decayed by capacitive bypass.
In the filter connector of the present utility model, adopt welding between contact and capacitance electrode, connector shell adopts the ground electrode flexibility termination of elastic spring and electric capacity, and the electric capacity that this flexible contact has been avoided ceramic material effectively is when being subject to the thermal shock mechanical stress and the damage that causes.
Filter connector of the present utility model, it comprises: an assembly welding is equipped with filtering contact assembly 2, one group of side set self-locking bonding plate 5 of the filter elements such as capacitor and inductor; In the hole on the filtering contact assembly 2 insertion side set self-locking bonding plates 5, realize that by the elastic claw 7 on the side set self-locking bonding plate 5 and bonding plate circumference flexibly connects; Side set self-locking bonding plate 5 is packed in the shell 1, and the Elastic Teeth 6 of its circle distribution is stuck on the step of metal shell 1 inwall, and side set self-locking bonding plate 5 is fixed in the shell 1 firmly, realizes that simultaneously circumference flexibly connects; The silicone rubber pad 4 of top arrangement a slice softness of side set self-locking bonding plate 5 makes electric capacity on the filtering contact assembly 2 avoid the rigidity extruding, avoids simultaneously the fluid sealant of embedding to be seeped into Elastic Teeth and above the elastic claw; Filter connector two ends embedding fluid sealant 8, blocking-up moisture enters.
Filter connector of the present utility model, the ground electrode of its filtering contact assembly 2 and side set self-locking bonding plate 5, side set self-locking bonding plate 5 are all realized flexible termination by elastic device with shell 1; Side set self-locking bonding plate 5 is the good sheet metals of elasticity, the regular hole that distributing on it, each hole be evenly distributed in one group of elastic claw 7; Side set self-locking bonding plate 5 be evenly distributed in one group of Elastic Teeth 6; Elastic Teeth 6 and elastic claw 7 are 45 ° to 135 ° angles with ground plate.
In sum, adopt the beneficial effect of the technical scheme of the utility model filter connector to be: the filtering contact assembly of the filter elements such as the capacitor and inductor that is welded is simple and reliable, and steady quality adopts and exempts from the weldering installation, the harmful effect that when avoiding secondary welding electric capacity is brought, and be convenient to maintain and replace; The application flexibility termination technology effectively stops electric capacity by rigid stress; Settle soft silicone rubber pad in capacitive side, electric capacity is played buffer protection function; All-sealed structure is guaranteed electric property good under wet condition.

Embodiment
Below with reference to drawings and Examples the utility model is further described:
The utility model filter connector, according to shown in Figure 1 its by metal shell 1, filtering contact assembly 2, interfacial seal pad 3, rubber blanket 4, side set self-locking bonding plate 5, fluid sealant 8 forms, filtering contact assembly 2 is inserted in the hole of side set self-locking bonding plate 5, elastic claw 7 around the hole tightly blocks the ground electrode of the filter capacitor on the filtering contact assembly 2, and Elastic Teeth 6 support tightly around the side set self-locking bonding plate 5 is on the step of shell 1 inwall, side set self-locking bonding plate 5 is fixed in the metal shell 1 firmly, realizes that simultaneously circumference flexibly connects; Side set self-locking bonding plate 5 is that the good sheet metal punching out of elasticity forms, and ground electrode and the metal shell 1 of the filter capacitor of filtering contact assembly 2 are realized reliably electrical connection.Electric capacity one side of side set self-locking bonding plate 5 is settled the silicone rubber pad 4 of a slice softness, when filter connector is subjected to thermal shock or mechanical stress, makes the filter capacitor on the filtering contact assembly 2 not damaged.The two ends embedding fluid sealant 8 of connector stops moisture to invade connector inside.
