Abstract
The utility model discloses a connector of nai pressurization, including the sealing -in casing, be equipped with the sealing -in hole in the sealing -in casing, the downthehole contact pin that is equipped with of sealing -in, the contact pin passes through the micrite pottery and sets up downtheholely in the sealing -in, the micrite pottery is located the middle section in sealing -in hole, the both ends in sealing -in hole adopt the plastics of moulding plastics to fill. The utility model discloses a connector, the sealing -in is downthehole with behind the micrite ceramic seal, and the packing of moulding plastics is adopted at both ends, arranges the downthehole air of sealing -in to the greatest extent for insulating properties reaches the demand under high -humidity environment.
Description
Technical field
The utility model relates to field of connectors, is specifically related to a kind of high-pressure-resistant sealed connector.
Background technology
Traditional connector, arranges many contact pins in a sealing-in hole, adopts micro-crystalline ceramic sealing-in.Many contact pin sealing-ins are in a sealing-in hole, and the bearing capacity of sealing-in place is poor.Micro-crystalline ceramic is directly exposed in air, and when in environment during high humidity, the insulation property of micro-crystalline ceramic can significantly decline, and cause the insulation property between sealing-in housing and contact pin not reach requirement.
Summary of the invention
The purpose of this utility model is: provide a kind of high-pressure-resistant sealed connector, sealing strength is high, high pressure resistant, resistance to high humility.
The utility model is achieved through the following technical solutions: a kind of high-pressure-resistant sealed connector, comprise sealing-in housing, sealing-in hole is provided with in described sealing-in housing, contact pin is provided with in described sealing-in hole, described contact pin passes through micro-crystalline ceramic sealing-in in sealing-in hole, described micro-crystalline ceramic is positioned at the stage casing in sealing-in hole, and the two ends in described sealing-in hole adopt injection-moulded plastic to fill.
As further preferred version of the present utility model, described injection-moulded plastic exceeds the end face in sealing-in hole.
As further preferred version of the present utility model, the partial shape that described injection-moulded plastic exceeds sealing-in hole end surface is consistent with the shape in sealing-in hole.
As further preferred version of the present utility model, the length that described injection-moulded plastic exceeds sealing-in hole end surface part is 5mm.
As further preferred version of the present utility model, in each sealing-in hole, be provided with a contact pin.
As further preferred version of the present utility model, described contact pin is located at the center in sealing-in hole.
Compared with prior art, the utility model has following beneficial effect:
One, connector of the present utility model, the independent sealing-in of each root contact pin is in a sealing-in hole, and sealing strength is large.
Two, connector of the present utility model, with after micro-crystalline ceramic sealing-in in sealing-in hole, two ends adopt mould filling, drain the air in sealing-in hole, make insulation property under high humidity environment reach demand.
Three, connector of the present utility model, injection-moulded plastic exceeds the end face in sealing-in hole, improves the proof voltage between contact pin and sealing-in housing.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, a kind of high-pressure-resistant sealed connector, comprise sealing-in housing 1, sealing-in hole 2 is provided with in described sealing-in housing 1, contact pin 3 is provided with in described sealing-in hole 2, described contact pin 3 is by micro-crystalline ceramic 4 sealing-in in sealing-in hole 2, and described micro-crystalline ceramic 4 is positioned at the stage casing in sealing-in hole 2, and the two ends in described sealing-in hole 2 adopt injection-moulded plastic 5 to fill.Described injection-moulded plastic 5 exceeds the end face in sealing-in hole 2, and the partial shape exceeding sealing-in hole 2 end face is consistent with the shape in sealing-in hole 2, and the length exceeding sealing-in hole 2 end face part is 5mm.Be provided with a contact pin 3 in each sealing-in hole 2, described contact pin 3 is located at the center in sealing-in hole 2.
