Abstract
The utility model discloses an assembly structure of a relay terminal and a moving spring. The moving spring is provided with two elastic clamping pieces with oppositely arranged clamping grooves. The terminal is provided with a flat connecting piece. While in assembly, the moving spring clamps two sides of the connecting piece of the terminal by the clamping grooves of the two elastic clamping pieces, and is pre-tightened at a certain position, and the moving spring and the connecting piece are fixed by welding. According to the utility model, the assembly is completed by pre-tightening and welding fixation, so that the restoring force of the moving spring is adjustable, and the product is adaptive to requirements and applications of different clients.
Description
Technical field
The utility model relates to the technical field of relay, the assembly structure of espespecially a kind of relay terminal and moving spring.
Background technology
(English name: be relay) a kind of electric control device, be when the variation of input variable (energizing quantity) reaches the regulation requirement to relay, in electric output circuit, makes controlled volume that a kind of electrical equipment that predetermined step changes occurs.It has control system (claim not only input circuit) and by the interactive relationship between control system (but also claiming output loop).Usually be applied in the control circuit of automation, it is actually a kind of " automatic switch " that goes to control large electric current running with little electric current.Therefore in circuit, play the effects such as automatic adjusting, safeguard protection, change-over circuit.
Relay generally is comprised of electromagnetic system, contact system, gigback and several parts of protection supporting construction, and wherein: electromagnetic system comprises: coil, iron core, support, armature; Contact system comprises: movable/fixed contact, reed, fixed terminal; Gigback is mainly the involution reed; The protection supporting construction comprises: shell and base.
In ISO Micro series relay, adopt on the structure of vertical coil on the market at present, be confined to the layout between product parts, adjustment in parameter, particularly in the adjustment of moving spring restoring force, can't be compensated and revise assembly accumulation error in process of production, cause the corresponding product parameter bad more.
Because moving spring restoring force can not carry out effectively and reliably adjusting, can't be suitable for multiple different Client application parameter request simultaneously.
The utility model content
When technical problem to be solved in the utility model is to provide a kind of assembling, the relay terminal that can adjust the restoring force of moving spring and the assembly structure of moving spring.
For solving the problems of the technologies described above, technical solution of the present utility model is:
The assembly structure of a kind of relay terminal and moving spring, described moving spring are provided with the elasticity card with draw-in groove of two, and the draw-in groove of two elasticity cards is and is oppositely arranged, and described terminal is provided with flat connecting portion; During assembling, this moving spring is clamped to the dual-side of the connecting portion of this terminal with the draw-in groove of its two elasticity card, and then pretension welds both is fixed in a certain position.
The cross section of described draw-in groove is U-shaped or C shape.
After adopting such scheme, two paired elasticity cards due to the utility model, have been designed on the moving spring of relay, the both sides that can clamp terminal connection part by this elasticity card, form resilient engagement, like this when assembling, can be according to the needs of different parameters, the corresponding adjustment moved the vertical height and position of spring on terminal, thereby the actual moving spring restoring force of effectively adjusting relay in assembling process, can eliminate simultaneously the accumulated error before this procedure assembling, weld again afterwards, the moving spring restoring force of setting is fixed up.The assembling mode that this first pretension is welded and fixed again, can reach the moving adjustable purpose of spring restoring force, makes product can be suitable for different clients' requirement and application.
The accompanying drawing explanation
Fig. 1 is three-dimensional exploded view of the present utility model;
Fig. 2 is three-dimensional combination figure of the present utility model;
Fig. 3 is the front view of moving spring described in the utility model;
Fig. 4 is the stereogram of moving spring described in the utility model.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
What the utility model disclosed is the assembly structure of a kind of relay terminal and moving spring, as shown in Figures 1 to 4, for preferred embodiment of the present utility model, described moving spring 1 is provided with the elasticity card 12 with draw-in groove 11 of two, and the draw-in groove 11 of two elasticity cards 12 is and is oppositely arranged, and described terminal 2 is provided with flat connecting portion 21.
During assembling, along the direction of arrow shown in Figure 1, be encased in described moving spring 1 on the connecting portion 21 of described terminal 2, with the draw-in groove 11 of its two elasticity card 12, clamp the dual-side of described connecting portion 21, structure due to elasticity card 12, can make spring 1 be stuck on terminal connection part 21 optional position and can landing, therefore can be according to the different parameters demand, by the moving a certain ad-hoc location of spring 1 pretension on terminal 2, then by the mode of welding, will move spring 1 and be fixed on this position, thereby realize the adjustable function of parameter.
Further, the cross section of described draw-in groove 11 can be U-shaped, also can be C shape.
The above, it is only preferred embodiment of the present utility model, not technical scope of the present utility model is imposed any restrictions, thus variation or the modification in every case according to claim of the present utility model and specification, done, within all should belonging to the scope that the utility model patent contains.
Claims (2)
1. the assembly structure of a relay terminal and moving spring, it is characterized in that: described moving spring is provided with the elasticity card with draw-in groove of two, and the draw-in groove of two elasticity cards is and is oppositely arranged, and described terminal is provided with flat connecting portion; During assembling, this moving spring is clamped to the dual-side of the connecting portion of this terminal with the draw-in groove of its two elasticity card, and then pretension welds both is fixed in a certain position.
