Abstract
The invention relates to a pouring structure and a pouring method of a micro-rectangular NM (network management) connector, which relate the connector pouring structure and the connector pouring method. The pouring structure and the pouring method of the micro-rectangular NM connector solve the pouring problem that the micro-rectangular connector and conductors with 0.055 mm cross section area in a narrow space can not meet the application reliability and the adaptability of the mechanical environment. An pouring body is positioned on the outer side of a connector shell, and is used for fixing and sealing insertion pins and the conductors, the insertion pins are inserted into the connector shell, the parts of the insertion pins, which are positioned at the connector shell part, are the head end of the insertion pins, and the parts of the insertion pins, which are positioned in the pouring body, are the tail end of the insertion pins. The tail end of each insertion pin is electrically connected with one end of one conductor, and the other end of the conductor, which is bent twice, is in the direction the same as that of the head end of the insertion pin. The pouring body is filled with a pouring sealant. The pouring method of the micro-rectangular NM connector comprises the steps of: vertically bending the conductors connected on the tail ends of the insertion pins in the pouring chamber, carrying out the first pouring on the bent conductors, vertically bending the conductors again after the first pouring, and carrying out the second pouring on the bent conductor. The pouring structure and the pouring method of the micro-rectangular NM connector are widely applied in the connector pouring in the narrow space.
Description
Technical field
The present invention relates to a kind of embedding structure for connector and method.
Background technology
Under high loading density, the wiring space of cable is narrow and small, and signal is various, the cable that high electrical-magnetic compatibility requires is easy to be destroyed, particularly when severe mechanical environment and narrow space, wire is easy to cabin body or miscellaneous equipment and mutually scratches and cause the problem of signal shorts or open circuit, causes the serious consequence of missile flight failure.
The outlet method embedding frock adopted at present is mostly simple, is easy to realize, but it is comparatively large to plug together the spatial volume that direction takies, and cannot use in the place of narrow space.The patent No. is adopted to be the use that 201110176643.8 " a kind of metal shell micro-rectangular connectors of tail encapsulation cavity groove at side surface " adapt to small space, but at present in the world the most microminiaturized, housing wall thickness be less than for the connector of 0.3mm, cannot relate to by structure the installation requirement that change adapts to small space.Therefore, adopt the cable of micro-rectangular connector and 0.055mm sectional area wire still cannot connect up in current space, more cannot meet the application reliability of cable under current space and mechanical environment adaptability.
Summary of the invention
The present invention in order to solve micro-rectangular connector and 0.055mm sectional area wire cannot meet application reliability and the adaptive embedding problem of mechanical environment at small space, thus provides a kind of micro-rectangular connector embedding structure and encapsulating method thereof.
The encapsulating method of the embedding structure of micro-rectangular connector, the embedding structure of micro-rectangular connector, it comprises connector shell, contact pin, wire and embedding body;
Described embedding body outside connector shell, for contact pin and wire are fixed sealing; Described contact pin inserts connector shell, and it is contact pin head end that described contact pin is positioned at connector shell part, and the part being positioned at embedding body is pin end; The pin end of every root contact pin is electrically connected with one end of a wire, and the other end of described wire is identical with contact pin head end direction through twice bending; Fill with in described embedding body and have casting glue;
Described embedding body and connector housing to be integrally fixed structure by embedding, and this integrative-structure is cuboid;
The thickness of described embedding body is identical with the thickness of connector shell, is the Width of embedding body along connector shell Width, and along the length direction for embedding body of connector shell length direction, and the length of embedding body is 11-13mm, and width is 9-11mm;
The method comprises the steps:
Step one: the wire be connected in pin end is vertically bent in encapsulation cavity;
Step 2: first time embedding is carried out to the wire after bending;
Step 3: the wire after first time embedding is vertically bent again;
Step 4: second time embedding is carried out to the wire after bending.
Described wire makes the direction of wire tail and contact pin head end identical through step one and step 3 twice vertical bending.
The wire radius of turn that the invention solves micro-rectangular connector embedding structure is little can adapt to the conflicting problem of the multiple constraints such as severe mechanical environment and small space.

Embodiment
Embodiment one, in conjunction with Fig. 1 and 2, this embodiment is described.Micro-rectangular connector embedding structure, it comprises connector shell 1, contact pin 2, wire 3 and embedding body 4; Described embedding body outside connector shell 1, for contact pin 2 and wire 3 are fixed sealing; Described contact pin 2 inserts connector shell 1, and it is contact pin head end that described contact pin 2 is positioned at connector shell 1 part, and the part being positioned at embedding body 4 is pin end; The pin end of every root contact pin 2 is electrically connected with one end of a wire 3, and the other end of described wire 3 is identical with contact pin head end direction through twice bending; Fill with in described embedding body 4 and have casting glue.
Embodiment two, this embodiment and embodiment one is integrally fixed by embedding with connector housing 1 unlike described embedding body 4, and this assembly is cuboid.
Embodiment three, this embodiment are identical with the thickness of connector shell 1 unlike the thickness of described embedding body 4 with embodiment one, along the Width that connector shell Width is embedding body 4, along the length direction for embedding body of connector shell 1 length direction, and the length of embedding body 4 is 11-13mm, width is 9-11mm.
Embodiment four, composition graphs 3 illustrate this embodiment.This embodiment is the encapsulating method of the micro-rectangular connector embedding structure described in embodiment one, and it comprises the steps:
Step one: the wire 3 be connected on contact pin 2 end is vertically bent in encapsulation cavity;
Step 2: first time embedding is carried out to the wire 3 after bending;
Step 3: the wire 3 after first time embedding is vertically bent again;
Step 4: second time embedding is carried out to the wire 3 after bending.
Embodiment five, this embodiment make the direction of wire tail and contact pin head end identical unlike described wire 3 through step one and step 2 twice vertical bending with embodiment four.
Carry out potting process through new encapsulating method of the present invention, the wire 3 be connected on contact pin 2 is bent on demand in embedding body 4, and with the wire 3 of casting glue protection sweep in embedding body 4.Wire 3 mechanical environment adaptability after embedding architecture advances is improved widely, in the process of dismounting guided missile wire 3 and above connector is damaged, broken skin, impaired accident significantly reduce, greatly save cost, ensure that project progress, no longer occurred that engineering wire 3 is installed impaired and delays progress.
When complicated and wiring space nervous and shielding conductor is various, particularly for micro-rectangular connector, potting process of the present invention needs to carry out at twice, and twice embedding is the bubble in order to better eliminate in casting glue, avoids bubble to reduce the insulation property of connector.
