Description

fixed iron

technical field

The utility model relates to a fixed iron sheet, in particular to a fixed iron sheet used for a male base of a sound box.

Background technique

At present, the contact piece of the sound box male base is used to connect the sound box female connector, and its structure generally includes a head, a bending part, a contact part and a spring pressing part. The fixed iron piece needs to be bent during production. The contact part of the fixed iron piece of the qualified sound box male base has a flat surface, but the processed contact piece will still have a flat surface of the contact part. The unevenness is caused by the bending deformation of the contact piece, which cannot be corrected by other methods, so there are the following defects: the fixed iron piece is not tightly connected to the speaker female connector, resulting in unstable signal transmission.

Contents of the invention

In view of the above-mentioned defects in the prior art, the purpose of this utility model is to provide a more tightly fixed iron piece when connected to the speaker female connector.

The technical solution of the utility model is: fix the iron sheet, including the iron sheet body, the iron sheet body includes a head, a bending portion, a contact portion and a spring pressing portion connected in sequence, the head is provided with a positioning hole, A curved hook is formed in the middle of the bending part, and a contact is provided on the top of the contact part, and a socket for the bottom end of the contact part is provided on the top of the contact part, and the bottom end of the contact part is After snapping into the jack, it is detachably connected with the contact part.

Further, two sliding grooves are evenly distributed on the side wall of the socket, and a concave annular groove is provided at the bottom end of the socket, and the groove communicates with the bottom end of the socket.

Further, the two sides of the bottom end of the contact point respectively have a protruding strip, and the bottom ends of the two protruding strips have outwardly extending blocks, and the two slide grooves are used for the corresponding blocks to be snapped in, and the blocks are inserted along the chute. Sliding into the groove, the locking block is slid into the groove and rotates with the groove.

Further, a spring is provided in the middle of the socket, and a protruding post is provided in the middle of the bottom end of the contact, and the protruding post presses on the spring.

Further, the head, the bending part, the contact part and the spring pressing part are of an integral structure.

The beneficial effect of applying the fixed iron sheet provided by the utility model is that a contact is provided on the top of the contact part, and a socket for the bottom end of the contact is provided on the top of the contact part, and the bottom end of the contact is clipped into the socket and connected with The contact part is detachably connected. When the iron body is connected to the speaker female connector, the contact directly contacts the speaker female connector, and the contact part does not contact the speaker female connector, and will not be affected by the uneven surface of the contact part. It can ensure stable signal transmission after connection, and because the contact is detachably connected with the contact part, it is also convenient to replace when the contact is damaged.

Detailed ways

In order to understand the technical scheme of the utility model more intuitively and completely, the non-limiting feature descriptions are as follows in conjunction with the accompanying drawings of the utility model:

As shown in Figures 1 to 5, the fixed iron sheet includes an iron sheet body 1, and the iron sheet body 1 includes a head 11, a bending portion 12, a contact portion 13 and a spring pressing portion 14 connected in sequence, and the head 11 is provided with The positioning hole 2 is formed with a curved hook 3 in the middle of the bending part 12. A contact 4 is provided on the top of the contact part 13. The top of the contact part 13 is provided with a jack 5 for the bottom end of the contact 4 to snap into. The bottom end of the point 4 is detachably connected with the contact part 13 after snapping into the jack 5 .

Two sliding grooves 6 are evenly distributed on the side wall of the jack 5 , and the bottom end of the jack 5 is provided with an indented annular groove 7 , and the groove 7 communicates with the bottom end of the jack 5 . Both sides of the bottom end of the contact 4 have a protruding strip 41 respectively, and the bottom ends of the two protruding strips 41 each have a block 411 extending outward, and the two chute 6 are for the corresponding block 411 to be snapped in, and the block 411 goes along the chute 6 slides into the groove 7, and the clamping block 411 slides into the groove 7 and rotates with the groove 7. A spring 8 is arranged in the middle of the socket 5 , and a boss 9 is arranged at the middle of the bottom end of the contact 4 , and the boss 9 presses on the spring 8 .

When installing the contact 4, first align the two protruding strips 41 at the bottom of the contact 4 with the chute 6 on the socket 5, and the block 411 at the bottom of the protruding strip 41 slides from the top of the chute 6 to the bottom, and the protruding strip 41 follows the Slide the chute 6 into the groove 7, at this time the spring 8 has been compressed by the boss 9, then pinch the contact 4 by hand and turn the contact 4 to a certain angle, as shown in Figure 5, at this time the contact 4 Turned 90 degrees, now the block 411 is firmly stuck in the groove 7, at this time the contact 4 is locked in the vertical direction, and because of the elastic force of the spring 8, the spring 8 presses the boss 9. The contact 4 is not easy to rotate, and the contact 4 needs to be rotated by hand. When the contact 4 needs to be removed, the contact 4 is rotated and the contact 4 is lifted up. When the block 411 slides to the position of the chute 6, the contact 4 is naturally removed.

The head 11 , the bending part 12 , the contact part 13 and the pressing part 14 are integrally structured. The overall structural strength of the iron sheet body 1 is improved.

In the fixed iron sheet provided by the utility model, a contact 4 is provided on the top of the contact part 13, and the top of the contact part 13 is provided with a jack 5 for the bottom end of the contact 4 to snap into. After the bottom end of the contact 4 snaps into the jack 5 It is detachably connected to the contact part 13. When the iron body 1 is connected to the female speaker connector, the contact 4 directly contacts the female speaker connector, and the contact part 13 does not contact the female speaker connector, and will not be affected by the contact part 13. The unevenness of the surface can ensure stable signal transmission after connection, and because the contact 4 is detachably connected to the contact part 13, it is convenient to replace the contact 4 when it is damaged.

Of course, the above are only preferred embodiments of the present utility model, and are not intended to limit the patent scope of the present utility model. All simple modifications and equivalent structural changes made by using the description and drawings of the present utility model shall be the same The theory is included in the patent protection scope of the present utility model.
