Abstract
Each metallic strip reel spring of a magnetic tape cassette is formed at one end with a base 13 having a non-circular aperture and is held against the inner surface of a casing by melted plastics material extending through the hole. The free end 15 bears against a reel mounted in the cassette in use and is bent up after securing the strip to the casing.
Description
The present invention relates to a kind of tape cassete.
Usually, the profile of tape cassete manufacture finely and also generally industrial by standardization, therefore, the different tape cassete in source can be assembled to and use in the tape player that each different manufacturers produce.The present invention is applicable to this standardized tape cassete and is particularly related to the spool spring that is installed in the box.
Proposed a kind of spool spring in the instructions of No. the 4770367th, United States Patent (USP), this spool spring is to two spool generation effects, and it comprises the stainless steel spring of a monolithic, and it is by suitably fixing and precast a suitable shape as required.
The objective of the invention is to make the amount of spool spring materials used to obtain reducing, and reduce the steepness value that forms.
Be provided with a spool spring that is used for tape cassete according to the present invention, this tape cassete comprises a resilient metal strip, and this resilient metal strip is provided with a basal plane at the one end, and it is configured to be connected on the tape cassete housing; This resilient metal strip have global shape from the acclivitous upright extension of basal plane, the far-end of extension is installed in the respective spools in the tape cassete when nestling up a job, wherein basal plane is provided with a non-circular hole, and run through and fill up this hole with the plastics scolder, it is fixed on the tape cassete housing.
By specific embodiment the spool spring of using according to a tape cassete of the present invention is described in conjunction with the accompanying drawings also now.Wherein:
Fig. 1 is the plan view of a tape cassete housing inboard of the present invention; With
Fig. 2 is the side view of two springs.
Shown in accompanying drawing, tape cassete housing 9 is made as required and according to industrial standard in Fig. 1, so that be suitable for being assemblied in any tape player commonly used when it assembles fully.Be provided with two spool springs 10 and 11, each spool uses a spring, and they all are installed on the main surface of housing, and have corresponding basal plane 12 and 13, and these basal planes nestle up above-mentioned surface in mode as described below and fix.These basal planes all have extension 14 and 15, and they tilt (seeing shown in Figure 2) upward from basal plane, and the far-end of its extension is to nestle up respective spools (not shown) in the box when it assembles fully.
Each of these spool springs has a non-circular center pit 16 and 17 on its basal plane, and basal plane is to be nested with on the unitary plastic part of the setting of housing, and use welding sequence and act on the working of plastics, thereby with plastic molting and make scolder be filled in hole 16 and 17 fully.Because the hole is non-circular, and spring can be securely fixed on the main surface of housing, can be suitable for particularly preventing that it from centering on pad or point of fixity is made relative circular motion.
This spring is to form with the SUS304 spring that flexible hardness 2B repairs, and it is thick to be 0.3 millimeter.In order to form the upstanding portion of spring, make basal plane 12 and 13 keep smooth, and apply the power that are about 160 grams at contiguous its far-end, this end is departed from and form an angle B that is about 20 °.Weldering knot in the welding of C place preferably protrudes about 0.03 millimeter from the top surface of spring.
What should give attention is just can replace the spring that is used for spool respectively by an independent spring is set for each spool, and generally or generally makes the formation spool obtain reducing with the required material of spring.
The integral part of erectting similarly is shaped with respect to the hole usually, and then sealing or tight cooperation make the part of setting near living the hole side to welding sequence simply.Also can provide additional
Claims (3)
1, a kind of spool spring that is used for tape cassete, it comprises a resilient metal strip, this bonding jumper is provided with a basal plane at the one end, it is configured to be connected on the tape cassete housing, this bonding jumper also have one integrally formed from the acclivitous upright extension of basal plane, the far-end of this extension nestles up a job and the time is installed in respective spools in the tape cassete, wherein basal plane is provided with a non-circular hole, run through and fill up this hole with the plastics scolder, so that it is fixed on the tape cassete housing.
2, according to the described spring of claim 1, wherein, the formation of upright extension is by fixed base and applies one with respect to the plane of basal plane the power at the crooked about 20 ° of angles of extension is realized.
3, the spool spring is here described basically in conjunction with the accompanying drawings.
