Description

A kind of elastic contact pin filter connector socket

Technical field

The present invention relates to technical field of electric connectors, relate in particular to a kind of elastic contact pin filter connector socket.

Background technology

Filter connector is a kind of filter of installing in inside, as electric capacity and magnet ring etc., makes the connector that self has certain anti-electromagnetic interference capability.

The filtered electrical that uses in the filter connector has tubulose electric capacity and tabular electric capacity.At present, generally take the rigidity welding way of contact in the filter connector between contact and the electric capacity.Welding is a kind of permanent way of contact, for filter contact, has low-down contact resistance, and stray inductance, dead resistance are also very little when high frequency, so have extraordinary fade performance; For grounding component, the contact resistance problem can be ignored basically.But welding in use, is subjected to the influence of mechanical stress, thermal shock etc. as a kind of rigidity termination mode, might cause the electric capacity crackle, and the adverse environment resistant ability is relatively poor.Therefore the flexible ends connection technology that filter connector need take to possess isolated mechanical stress, cold-and-heat resistent impacts is protected electric capacity to greatest extent.

Summary of the invention

The object of the present invention is to provide a kind of elastic contact pin filter connector socket,, improve the resistance to shock and the reliability of product by the contact pin that use has resilient contact structure.

A kind of elastic contact pin filter connector socket comprises shell, pedestal, rubber blanket a, capacitor board, grounding reed, rubber blanket b, baffle plate, contact pin, weldering cup, hat spring, fluid sealant a, fluid sealant b; Described contact pin tail end is a notching construction, and contact pin and capacitor board contact site are the bulge structure; Described pedestal and contact pin are located in the filter connector shell, fix by fluid sealant b embedding, and capacitor board integral body is located at the contacted position of bulge structure of contact pin.Capacitor board is equipped with grounding reed in two ends up and down, and the capacitor board left and right sides is provided with rubber blanket a and rubber blanket b, and baffle plate is isolated with fluid sealant a and rubber blanket b; The hat spring is located in the weldering cup.

Described electric capacity and grounding reed are Elastic Contact,

Described capacitor board is by the Elastic Contact of grounding reed and shell.

Adopt the beneficial effect of technique scheme to be:

By the contact pin that use has resilient contact structure, make Elastic Contact between capacitor and the contact, thereby improve the resistance to shock and the unfailing performance of product.Above-mentioned filter connector socket is simple, easy to assembly, use is reliable and satisfy equipment lightness, reliability height and the strong requirement of antijamming capability.

Among the figure: 1-shell, 2-pedestal, 3-rubber blanket a, 4-capacitor board, 5-grounding reed, 6-rubber blanket b, 7-baffle plate, 8-contact pin, 9-weldering cup, 10-hat spring, 11-fluid sealant a, 12-fluid sealant b.

Embodiment

Below in conjunction with accompanying drawing the present invention is described in further detail:

As shown in Figure 1, above-mentioned filter connector socket comprises: shell 1, pedestal 2,

rubber blanket

3 and 6, capacitor board 4, grounding reed 5, baffle plate 7, contact pin 8, weldering cup 9, hat spring 10 and

fluid sealant

11 and 12 etc.

As shown in Figure 2, contact pin 8 is designed to be provided with notching construction at tail end, and the contact site of contact pin 8 and capacitor board 4 is designed to the bulge structure, like this in contact pin 8 and realization Elastic Contact when capacitor board 4 contacts.

The embodiment of filter connector socket of the present invention is:

Pedestal 2 and contact pin 8 are packed into behind the above-mentioned filter connector shell 1, and the good fluid sealant 12 of embedding reinstalls rubber blanket 3 and grounding reed 5, subsequently capacitor board 4 integral body are pressed into to the contacted position of bulge structure of contact pin 8.Wherein electric capacity 4 be Elastic Contact with grounding reed 5, guarantees that above-mentioned filter connector socket capacitor board 4 when bearing vibratory impulse can not bump with shell 1 to cause damage, has guaranteed the reliable ground of capacitor board 4 simultaneously.Rubber

blanket

3 and 6 can play the efficient buffer protective effect when capacitor board 4 bears vibratory impulse.Capacitor board 4 has been realized the good earth of electric capacity by the Elastic Contact of grounding reed 5 with shell 1.Fluid sealant 11 and fluid sealant 12 can effectively be protected electric capacity not to be subjected to the intrusion of moisture and cause losing efficacy.

Hat spring 10 is packed in the weldering cup 9, and contact pin 8 is realized being electrically connected continuous by hat spring 10 and weldering cup 9, form whole contact pin structure, and such design can reduce the diameter of contact pin 8, and then reduces the through-hole diameter of capacitor board 4, the capacity of expanded capacitor plate 4.Baffle plate 7 is isolated with rubber blanket 6 with fluid sealant 11, has stopped glue and has flow to capacitor board 4 surfaces, causes that capacitor board 4 makes moist by rubber blanket 6 holes, and the phenomenon that reduces the dielectric voltage withstand performance takes place.
