Abstract
A jack insulator for multi-core electrical connector comprises a rear jack insulator with a group of jack mounting holes and is characterized by further comprising a front jack insulator. The front jack insulator is provided with a group of guide holes, the shapes and the positions of the guide holes correspond to the shapes and the positions of the jack mounting holes of the rear jack insulator, the jack mounting holes at the adjacent ends are annular bosses, the guide holes at the adjacent ends are concave holes, and the rear jack insulator is fixedly connected with the front jack insulator through bolts or screws. When pins are inserted in jacks, guiding effect of the front jack insulator is exerted on the pins, the pins cannot be distorted in the inserting process, and the pins can smoothly and accurately enter into the jacks in the inserting process, thereby achieving reliable connection. When contact pieces need disassembling, only the front jack insulator needs to be taken down, the contact pieces can still be disassembled from the front end, thereby being convenient to disassemble. The jack insulator is applied to the electrical connector with a plurality of cores, thereby effectively improving contact reliability on the premise that the operability of the electrical connector is guaranteed.
Description
Technical field
The utility model belongs to the parts of electric connector, relates to a kind of multicore electric connector and uses the jack insulator, is that prior art is improved, and the electric connector that is specially adapted to core number many (for example: more than 30 cores) adopts.
Background technology
Electric connector is made up of plug and socket, comprises housing, insulator, contact (being made up of contact pin and jack) three big elementary cells.Under the many situation of electric connector core number, the processing and manufacturing difficulty that is used to assemble the insulator of contact strengthens, and position, hole coordinate dimension tolerance grade requires to improve; Because after plug and socket plugs together, all contact pins must insert in the jack fully, if there is a contact that deviation is appearred in position dimension; Headstock will not be plugged together, even as for fatal problem occurring, contact pin ejects jack in insulator; It is unreliable to cause contacting, and can't realize the transmission of electricity.In the prior art, the positive bore size of the insulator of dress jack can guarantee that contact pin inserts fully, but can't lead to contact pin; In the process of plugging together, or jack ejected, or contact pin is ejected; In this process, can damage the elastic component on insulator and the contact; Cause and can't reuse, connector contact in this case is unreliable, and connector is difficult to normal use.
Summary of the invention
The purpose of the utility model is intended to overcome above-mentioned deficiency of the prior art; Through the jack insulator being changed before the jack behind the insulator and jack into insulator etc., provide a kind of simple in structure, realize that contact pin uses the jack insulator with the multicore electric connector that jack reliably is connected.
The utility model solves the technical scheme that its technical problem adopted: a kind of multicore electric connector is used the jack insulator, comprising: insulator behind the jack that one group of jack installing hole arranged is characterized in that also comprising:
The corresponding pilot hole of jack installing hole that insulator (2) behind one group of shaped position and the said jack is arranged in the insulator (1) before the insulator (1) before jack, this jack; Be used for before contact pin and jack plug together, contact pin being play the guiding role;
Insulator behind the said jack (2) is connected through bolt or screw with the preceding insulator (1) of jack.
In the technical scheme of the utility model: in the pilot hole of the preceding insulator (1) of the jack installing hole of insulator behind the said jack (2) and jack; Each jack installing hole of an adjacent end is that annular boss (7), pilot hole are shrinkage pool (8), to guarantee that the two is in axial unanimity.
In the technical scheme of the utility model: the center of insulator behind the said jack (2) has the center of axial thread hole (4), the preceding insulator (1) of said jack that axial hole is arranged; And the preceding insulator (1) of insulator behind the jack (2) and jack is fixedly connected through screw (3); Make before the jack that insulator (2) is more convenient when being connected behind the insulator (1) and jack; Assembling and dismounting are all simple, enhance productivity.
Compared with prior art, the utlity model has following characteristics and beneficial effect:
(1) adopt the utility model, before the jack behind insulator and the jack insulator cooperate with protruding hole (being annular boss) through shrinkage pool, position, the hole size that makes the front and back insulator is in an axle center, and is good to neutrality; Before contact pin inserted jack, contact pin received the guide effect of the preceding insulator of jack, made and in the process of inserting, must not distort that easy to assembly, headstock plugs together in the process, and contact pin can get in the jack smoothly and accurately, guaranteed to realize reliably connection to inserting; In the time of need dismantling contact, only need screw is screwed out, take off the preceding insulator of jack, can realize still that then unloading is convenient from the mode of front end dismounting contact;
(2) the utility model is applied in the connector of core number many (for example: 30 cores above); Under the prerequisite that guarantees the electric connector operability; Can effectively improve the reliability of contact, and make accessory loss minimizing on the electric connector, increased the mechanical endurance of electric connector;
(3) simple in structure, produce easy to install, practical.

Fig. 4 is that the utility model is implemented illustration user mode structural representation.
Among the figure: insulator, 3-screw, 4-screwed hole, 5-jack, 6-contact pin, 7-annular boss, 8-shrinkage pool behind the preceding insulator of 1-jack, the 2-jack.
Embodiment
The utility model is described further through embodiment below in conjunction with accompanying drawing.
Embodiment 1: referring to each accompanying drawing.
A kind of multicore electric connector is used the jack insulator; Comprise: one has one group of insulator 2 behind the jack of totally 60 jack installing holes; Also comprise: insulator 1 before the jack; One group of corresponding pilot hole of jack installing hole of insulator 2 behind totally 60 shaped positions and the said jack is arranged in the insulator 1 before this jack, be used for before contact pin and jack plug together, contact pin being play the guiding role;
In the pilot hole of the preceding insulator 1 of the jack installing hole of insulator 2 and jack, each jack installing hole of an adjacent end is that annular boss 7, pilot hole are shrinkage pool 8, to guarantee that the two is in axial unanimity behind the said jack;
The center of insulator 2 has the center of axial thread hole 4, the preceding insulator 1 of said jack that axial hole is arranged behind the said jack; And insulator 1 before insulator behind the jack 2 and the jack is fixedly connected through screw 3; Make when insulator 2 is connected behind the insulator 1 and jack before the jack more convenient; Assembling and dismounting are all simple, enhance productivity.
During use; In one of insulator 2 group of jack installing hole jack 5 is installed respectively behind the jack, the pilot hole of contact pin 6 insulator 1 before jack is axially inserted, under the effect that the shrinkage pool 8 of insulator 1 cooperates before annular boss 7 of jack 5 insulator 2 behind jack (being protruding hole) and the jack; Retainer shaft to; Therefore, contact pin 6 can insert in the jack 5 smoothly, realizes reliably connecting.
Adopt this embodiment, when electric connector core number (for example: 30 cores above) is many, under the prerequisite of the operability that guarantees electric connector, can realize reliable connection.
The utility model is not limited to the foregoing description, and the utility model content is said all can implement and have said good result.
