Abstract
The invention discloses a waterproof sealing electric connector which comprises an upper shell, a lower shell, a support plate, embedded nuts and contact elements on an upper insulation seat and a lower insulation seat. The waterproof sealing electric connector is characterized in that each contact element is made of an elastic conductive material via punching; a jack is formed in one end of each contact element, a slot is formed in the other end of each contact element, and a plastic plug is arranged at the joint part of the jack and the slot to block off the jack; the embedded nuts are connected with the lower shell via flanging and pressure riveting; the upper and lower insulation seats are clamped on the support plate after being sheathed with the upper and lower shells; the lower and upper shells are fastened by bolts and the embedded nuts after being buckled; a sealant is filled in the mounting gap of the support plate and the lower shell so as to realize the reliable waterproof sealing of the punched contact elements. Compared with the prior art, the waterproof sealing electric connector has the advantages that the workmanship is simple, the production cost is low, the waterproof sealing property is good, and the performance-price ratio and the competitiveness of the product are greatly enhanced; the anti-rotation capability of the embedded nuts is strong, and therefore, the waterproof sealing electric connector is particularly applicable to humid environments or other severe work environments.
Description
Technical field
The present invention and technical field of electronic components, especially a kind of waterproof sealing electric connector.
Background technology
In the interconnection of existing electronic circuit, power connector is requisite components and parts in the power circuit interconnection system.In the real work of communication equipment, especially require protection against the tide and the water resistance of electric connector, to satisfy electric connector installing and using at moist or other abominable operational environment.Current electron trade dog-eat-dog, model change is exceedingly fast, and the rate of gross profit of electronic product is in continuous decline, and the waterproof sealing connector need to be to miniaturization and the higher future development of cost performance.
At present, the waterproof sealing electric connector of supplying on the market adopts connector and supporting bracket to fix the mode of rear filling and sealing glue, realizes the waterproof sealing performance of product.Such as accompanying drawing 1 ~ shown in Figure 3, connector comprises contact 13, embedded nut 11, sheath 12, top base 19 and bottom base 20, the fixing of connector turns over riveting in the restriction of sheath 12 realization upper and lowers to the degree of freedom by embedded nut 11, utilize the square opening between the shell 14 on embedded nut 11 and the connector to limit the rotation of embedded nut 11, thereby realize being completely fixed of connector and supporting bracket 17, then realized the waterproof sealing performance of whole product by fluid sealant 15.As shown in Figure 4, contact 13 is car workpiece processed, and difficulty of processing and production cost are higher.
The waterproof sealing structure of prior art can only use the contact of car system processing, although car contact processed is easily realized the good waterproof sealing of connector, operates fairly simple, convenient.Connector uses car contact processed at waterproof sealing certain advantage to be arranged, but the processing cost of car contact processed is higher, is unfavorable for promoting cost performance and the competitiveness of connector, and nut anti-rotation ability, easily produces during screw fastening and skids.
Summary of the invention
The objective of the invention is a kind of waterproof sealing electric connector of designing for the deficiencies in the prior art, the anti-rotation structure that adopts punching contact and supporting bracket to cooperate with embedded nut, Effective Raise waterproof sealing performance and the embedded nut anti-rotation of connector, simple in structure, easy to assembly, further reduce the processing cost of product, and the reliability that connects is high, product quality is more stable, especially is fit to installing and using of moist or other abominable operational environment.
The object of the present invention is achieved like this: a kind of waterproof sealing electric connector, comprise lower house, upper shell, supporting bracket, embedded nut and be arranged on contact on the upper and lower insulating base, be characterized in that described contact is formed by the elastic conducting material punching, the one end is jack, the other end is slot, and the joint portion of jack and slot is provided with plastic plug shutoff jack; Described embedded nut is arranged on the lower house, and embedded nut and lower house are that flange presses and is connected; Be installed on the supporting bracket behind described upper and lower insulating base and the upper and lower casing suit, lower house and upper shell are fastening by screw and embedded nut after fastening, the fixing clearance perfusion fluid sealant of supporting bracket and lower house realizes that fluid sealant is to the reliable waterproof sealing of punching contact.
The present invention has compared with prior art that manufacture craft is simple, and production cost is low, and waterproof sealing is functional, has greatly promoted cost performance and the competitiveness of product, and the anti-rotation ability of embedded nut is strong, especially is fit to installing and using of moist or other abominable operational environment.

Embodiment
Embedded nut 10 directly turns over riveting and realizes upper and lower to the restriction of the degree of freedom at shell 6, and embedded nut 10 utilizes its rotation of rectangle engagement limits with supporting bracket 8.Like this since the distance of anti-rotation than prior art long a lot, so embedded nut 10 can bear larger moment of torsion, Effective Raise the anti-rotation of embedded nut 10.The contact 5 of punching is because the process technology limit of processing and fabricating, be difficult to realize the waterproof sealing of connector, the present invention realizes good waterproof sealing performance for the contact 5 that makes flushing technology processing at connector, the jack 51 that has been provided with plastic plug 3 effective shutoff in the hole slot joint portion of contact 5 is so that fluid sealant 1 is realized the reliable waterproof sealing of punching contact 5.
More than just the present invention is further illustrated, is not to limit this patent, all for the present invention's equivalence enforcement, all should be contained within the claim scope of this patent.
