Abstract
The utility model relates to a non-metal external tooth cover for a crimping connector, which is characterized in that the external tooth cover is made from non-metal materials, and the shape of which is an elastic annular table pyramid with an opening. The utility model has the advantages of one-step molding, low cost and stable quality. The external tooth cover is respectively contacted with the contact body of a connector and the hole wall of a mounting plate, the contact is planar contact. The contact surface is large, so the retentivity of the contact body in the mounting plate is great, the floating self-centering effect is good, and the coaxiality and the structural reliability are obviously enhanced.
Description
The utility model relates to the parts of line connector, and particularly a kind of nonmetal external tooth cover of compression connector is the improvement of prior art.
In order to adapt to the needs that electronics industry develops rapidly day by day, miniaturization, highly reliable, long-life interconnecting devices are favored in growing field.Its mode of connection of old-fashioned interconnecting devices adopts welding more, and its shortcoming is manual operations, is easy to generate rosin joint; During welding, scolder extends along lead, makes that section lead weldering is dead, hardening, when being vibrated or impacts, and generation " internal injury " and rupturing; Solder flux also can polluted product, produces the quality destabilizing factor, and in miniaturization, highdensity product structure, welding manner has tangible limitation and non-operability.At the eighties initial stage, the crimp termination technology begins the extensive promotion and application in China, and till now, the termination mode of satellite, airship, carrier rocket 90% all adopts compression joint type; Crimping is to peel off the bare wire of insulating barrier one end, inserts the contact afterbody and prepares to be used in the cavity of crimping, and exerting pressure with special instrument makes the cavity distortion, lead is crimped on together tightly, thereby realizes its termination.Because compression joint type has operation under the normal temperature, dielectric can not scalded and be out of shape; Form " the pressure welding welding area " of a simple metal in crimping place, can stop a tangential gas to enter the metal interface, eliminate rosin joint, and tensile strength is higher by 50% than welded type, reliability of products is good mechanical electric performance such as raising obviously, thereby is subjected to all circles and pays close attention to widely.
In the prior art, compression connector generally by upper mounting plate, the lower installation board of insulation, form by one group of internal tooth casing or external tooth cover and a winding contact; Upper and lower mounting panel is overlapping and respectively have one group of hole and position corresponding one by one, one winding contact places each corresponding aperture of upper and lower mounting panel respectively, internal tooth casing or external tooth cover play the axial location effect, and a winding contact is distinguished axial location in each corresponding aperture of last lower installation board.Existing external tooth cover, by metal material (for example: the Elastic Circular annular tooth cover of the opening of copper strips etc.) making, the external tooth that puts the symmetrical distribution of punching out at tooth constitutes; During use, external tooth cover is assemblied in the contact of positioning step, pushes together in the mounting panel, external tooth hangs on the positioning step of mounting panel, makes contact axial location in mounting panel.Adopt this external tooth cover, owing to only depend on the support of external tooth to make the contact location, contact-making surface is less, thereby contact is relatively poor in the confining force and the axiality of mounting panel.
The purpose of the utility model is intended to overcome above-mentioned deficiency of the prior art, and by adopting the one-time formed elasticity external tooth cover of nonmetallic materials, a kind of contact-making surface is big, the nonmetal external tooth cover of the very easy compression connector of manufacturing thereby provide.
Content of the present utility model is: a kind of nonmetal external tooth cover of compression connector, its feature part is: this external tooth cover (for example: the resilient open annular platform shape cone of macromolecular materials such as plastics, rubber) making (1) be shaped as nonmetallic materials.
In the utility model content: the outside hypomere in the vertical section of described open annular platform shape cone (1) is the straightway (2) parallel with open annular platform shape cone (1) central axis, with the contact-making surface of increase with the mounting panel hole wall.
In the utility model content: the cone angle of affiliated open annular platform shape cone (1) is 15～35 ° preferably.
Compared with prior art, the utlity model has following characteristics:
(1) external tooth cover adopts the nonmetallic materials manufacturing, and one-shot forming is produced easily, and production efficiency height, cost are very cheap, and steady quality, high conformity;
(2) between external tooth cover and the contact, be face between the hole wall of external tooth cover and mounting panel and contact, contact-making surface is big, makes contact confining force in mounting panel big, floats that self-centering is effective, axiality and structural reliability obviously strengthen.
Fig. 1 is the utility model embodiment vertical section structure schematic diagram;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the utility model embodiment user mode reference configuration schematic diagram.
Among the figure: 1-open annular platform shape cone, 2-straightway, 3-opening, 4-contact.
Be an embodiment of the present utility model below.
Referring to each accompanying drawing.A kind of nonmetal external tooth cover of compression connector, this external tooth cover is made by nonmetallic materials, it is shaped as resilient open annular platform shape cone 1, and the outside hypomere in its vertical section is and the parallel straightway 2 of open annular platform shape cone 1 central axis that the cone angle of open annular platform shape cone 1 is 30 °.
During use, this nonmetal external tooth cover is socketed on the contact 4 of positioning step, push in the mounting panel together, the following end periphery of nonmetal external tooth cover hangs on the mounting panel positioning step and the hypomere outer peripheral face contacts with the mounting panel wall surface of the hole, makes confining force and the axiality of contact in mounting panel good.
The utility model is not limited to the foregoing description, and the utility model content is described all can be implemented.
Claims (3)
1. the nonmetal external tooth cover of a compression connector is characterized in that: this external tooth cover be shaped as the resilient open annular platform shape cone (1) that nonmetallic materials are made.
2. by the nonmetal external tooth cover of the described compression connector of claim 1, it is characterized in that: the outside hypomere in the vertical section of described open annular platform shape cone (1) for the straightway (2) of the flat shape of open annular platform shape cone (1) central axis.
3. by the nonmetal external tooth cover of claim 1 or 2 described compression connectors, it is characterized in that: the cone angle of affiliated open annular platform shape cone (1) is 15～35 ° preferably.
