Abstract
The utility model discloses a demountable contact element fixing structure, which comprises an insulator, a locking ring, and a contact element. A step mounting hole corresponding to the locking ringand the contact element outline is arranged on the insulator, the locking ring is sleeved outside the contact element, and arranged in the step mounting hole of the insulator meanwhile, the locking ring shrinks under the action of the radial force of the insulator to realize fixation, and the locking ring can smoothly be withdrawn through compressing the locking ring to cause the radial size of the locking ring to dwindle, when in disassembly. The utility model has the advantages of simple and reliable structure, and quick assembly and disassembly, and suits the lot sizing production, can be used as various contact fixed structures, and has better popularization and application values.
Description
Technical field
The utility model belongs to and relates to a kind of detachable contact fixed structure, belongs to technical field of electric connectors.
Background technology
Electric connector contact fixedly comprise the fixing of contact pin and jack, its fixed form includes: 1) adopt split washer to fix; 2) the barb interference fit is fixed; 3) pack into support spring circle and bonding back fixed contact therefor of double-body bike insulator.Can adopt different fixed structure forms according to actual use occasion.But in above-mentioned several structure, split washer structure, barb over-surplus fit structure are generally non-dismountable, and the barb interference fit to require insulating material be the high tenacity material.Double-body bike insulator pack into support spring circle and bonding back fixed contact therefor, its insulator is a double-body bike, two insulators need be adhesively fixed, and needs the metal shell protection simultaneously, the volume of its connector is bigger.Therefore, said structure can't solve the less integral type insulator of bulk the fixing and maintenance of connector contact the time the detachability requirement.
The utility model content
The purpose of this utility model is primarily aimed at the deficiency of said structure, provides to get detachable contact new construction before sending after a kind of, realize contact fast, secure fixation and detachability.
Detachable contact fixed structure described in the utility model, form by insulator, binding ring and contact, insulator is provided with the step installing hole corresponding with binding ring and contact profile, binding ring is sleeved on outside the contact, be installed on simultaneously in the insulator step installing hole, this installing hole shrinks binding ring under its radial load effect.
Described contact middle part is provided with two steps, and external diameter is corresponding with the binding ring endoporus between two steps, and binding ring is stuck between two steps of contact middle part.
Described binding ring is the opening annulus, axially has perfectly straight groove, and the cylindrical of binding ring one end is the circular cone inclined-plane, and the other end is the face of cylinder, between the described circular cone surface bottom and the face of cylinder protrusion step is set.
Described binding ring is by the beryllium-bronze material manufacturing.
The fixed structure of the utility model connector contact simply, reliably assembles, dismantles fast, is suitable for mass production, and is all suitable to the insulator fixed contact therefor of rigid plastics, brittle plastic and toughened plastic.The integral type insulation fixed contact therefor that is in particular the thermoplastics of hard brittle plastic of thermosetting class and fragility provides a kind of practical and effective organization plan, has application value preferably.

Embodiment
Below in conjunction with the accompanying drawing example the utility model is described in further detail:
As shown in Figure 1, detachable contact fixed structure described in the utility model is made up of insulator 1, binding ring 2 and contact 3, insulator is provided with the step installing hole corresponding with binding ring and contact profile, binding ring 2 is sleeved on outside the contact 3, be installed on simultaneously in the insulator step installing hole, this installing hole shrinks binding ring under its radial load effect.
Binding ring 2 is the opening annulus, by the beryllium copper made of high elastic modulus, axially opens direct through groove 23 along circumference during making, and binding ring 2 cylindricals one end is circular cone inclined-plane 21, and the other end is the face of cylinder, and step 22 is set between the bottom on circular cone inclined-plane and the face of cylinder.
Contact 3 can be contact pin or jack, with after binding ring 2 assembling as shown in Figure 5.Contact 3 middle parts are provided with step 31,34, diameter is less than step 31,34 places between two steps, corresponding with the binding ring endoporus, for ease of dismounting, will be set to enlarged diameter section 321 and reduced diameter section 322 herein, binding ring 2 is stuck between 3 liang of steps of contact 31,34, binding ring tapered slope 21 ends are installed in reduced diameter section 322 places, contact middle part, the binding ring cylindrical end is installed in enlarged diameter section 321 places, and binding ring can radially freely rotate like this, and axial endplay is by step 31,34 restrictions at two ends.
Insulator 3 is provided with the stepped hole of fixing and locking ring, wherein is provided with the chamfering 11 that play the guiding role at the end of packing into, is convenient to binding ring 2 and packs in the insulator 3 with contact 3, and the other end that plays fixation is provided with step 12.
After binding ring and contact were packed in the insulator, binding ring 2 is radial contraction between insulator and contact, and insulator step 12 to the binding ring extreme direction motion of packing into, is realized the secure fixation of contact 3 in order to restriction contact 3.When needs dismounting binding ring 2, with specific purpose tool compression ramp 21, binding ring 2 radial dimensions are diminished, from insulator 1, withdraw from smoothly, realize detachable.
