Abstract
The utility model belongs to power transmission field, and relates to a multi-column roller contact with double-surface restriction. The double-surface-restrained multi-column roller contact comprises a housing, guide columns and a holding rack assembly; wherein one end of the housing is open and a pair of opposite surfaces is provided with guide column holes; the guide column are arranged in the guide column holes; the surface of each guide column has a threaded structure; the other pair of opposite surface is provided with guiding grooves and mounting holes; and each mounting hole is provided with a thread; and the holding rack assembly is mounted in the housing; and the holding rack assembly is connected with the housing through the guide columns and is restrained by the guiding grooves. According to the double-surface-restrained multi-column roller contact provided by the utility model, because a plurality of rollers contact with the pin, linear contact and large contact surface are realized. Therefore relatively large current can be conducted. Furthermore small plugging force and longer service life are realized.
Description
Technical field
The utility model belongs to transmission of electricity (electricity) field, relates to a kind of multiple row roller-contact part with bilateral constraint.
Background technology
When in front socket mainly with panel beating as contact, the latch inserting by the elastic clamping of the material of panel beating own, thus realize contact conduction.Its feature is as follows:
When latch inserts, between itself and contact, there is relative sliding, have dry friction phenomenon to produce, insert resistance large.
The sheet metal component directly contacting with latch all can be out of shape in the time of each plug, and meeting of a specified duration produces fatigue fracture.
Its contact can only have one or a butt contact.Because the resistance of metal and the area of contact point are inversely proportional to.Therefore the size of contact point area has determined its size of current that can transmit.
The current ball roller that also has a kind of socket contact to use unilateral constraints, its contact area is to be determined by the size of roller.Therefore when a ball roller contacts with latch, also can not produce larger contact area, and latch can only unidirectionally regulate while inserting contact.
Utility model content
The purpose of this utility model is: a kind of multiple row roller-contact part with bilateral constraint for socket is provided.
The technical solution of the utility model is: a kind of bilateral constraint multiple row roller-contact part, and it comprises shell, guide pillar, retainer assembly, wherein, shell one end opening, one opposite is provided with guide pillar hole, guide pillar is arranged in guide pillar hole, and surface is with helicitic texture, and another opposite of shell is provided with guide groove and installing hole, installing hole is provided with screw thread, retainer assembly is installed in the enclosure, and is connected by guide pillar between shell, and by guide groove constraint.
Described retainer assembly comprises wavy spring, some cylinders, and double-screw bolt, retainer, described double-screw bolt one end is provided with screw thread, and other end is provided with straight screwdriver groove; Cylinder is tubular structure; There are two rounds at the edge of retainer, on hole, there is screw thread to coordinate with double-screw bolt, there are two punching hole in centre, on hole, there is screw thread to coordinate with guide pillar, described drum sleeve is on double-screw bolt, the two ends that double-screw bolt surface has screw thread to coordinate and expose double-screw bolt with retainer, are stuck in the guide groove of shell, and its end face is concordant with the outer surface of shell.
Described cylinder outer cylinder surface is provided with groove.
Advantage of the present utility model: the utility model bilateral constraint multiple row roller-contact part is because multiple rollers contact with latch, and be line contact, contact area is large, therefore can pass through larger electric current, has significantly increased the available horsepower of socket.And due under identical normal pressure, rolling friction is less than dry friction, therefore significantly reduce pulling-inserting force.In addition, owing to having adopted Compress Spring, compared with ball reed, increased plug number of times, fatigue strength obviously increases, and therefore the life-span is longer.

Embodiment
Below by specific embodiment, the utility model is described further:
Please refer to Fig. 1 to Fig. 4, the utility model bilateral constraint multiple row roller-contact part comprises shell 1, guide pillar 2, retainer assembly 3.Wherein, shell 1 is frame structure, one end opening, an opposite is provided with guide pillar hole, and guide pillar 2 is arranged in guide pillar hole, surface is with helicitic texture, another opposite of shell is provided with guide groove and installing hole, and installing hole is provided with screw thread, and retainer assembly 3 is installed in the enclosure, and be connected by guide pillar 2 between shell 1, and by guide groove constraint.
As shown in Figure 2, described retainer assembly 3 comprises wavy spring 4, some cylinders 5, and double-screw bolt 6, retainer 7, described double-screw bolt 6 one end are provided with screw thread, and other end is provided with straight screwdriver groove.Cylinder 5 is tubular structure, and outer cylinder surface is provided with groove.There are two rounds at the edge of retainer 7, on hole, there is screw thread to coordinate with double-screw bolt 6, there are two punching hole in centre, on hole, there is screw thread to coordinate with guide pillar 2, described cylinder 5 is enclosed within on double-screw bolt 6, there are screw thread and the two ends that retainer 7 coordinates and expose double-screw bolt 6 in double-screw bolt 6 surfaces, are stuck in the guide groove of shell 1, and its end face is concordant with the outer surface of shell 1.
Refer to Fig. 5, it is the scheme of installation of the utility model bilateral constraint multiple row roller-contact part.When actual use, each uses two contact heads mutually, forms the bilateral constraint to latch, and the number of phases of socket can be set as required, and if desired two-phase socket, places two contacts and on Socket casing, use screw-driving.In like manner, if desired three-phase, arranges three contacts on Socket casing.In addition, due to the cylinder groove that oils, so the socket based on this contact design is equally applicable to round end latch.
The utility model bilateral constraint multiple row roller-contact part is because multiple rollers contact with latch in sum, and is line contact, and contact area is large, therefore can pass through larger electric current, has significantly increased the available horsepower of socket.And due under identical normal pressure, rolling friction is less than dry friction, therefore significantly reduce pulling-inserting force.In addition, owing to having adopted Compress Spring, compared with ball reed, increased plug number of times, fatigue strength obviously increases, and therefore the life-span is longer.
