Description

Technical Field

[0001] The invention belongs to the technical field of circuit conversion switches, and in particular relates to a multi-channel sliding conversion switch. Background Art

[0002] The circuit conversion switch uses travel or mechanical force as the control instruction to realize circuit conversion. It is widely used in mechanical equipment and weapon control systems. The structure of the traditional multi-channel sliding conversion switch includes springs, mounting seats, male connectors, female connectors, follower blocks, guide rods, screws, etc. Each structure adopts a splicing design. Specifically, the female connector is built into the mounting seat and locked by screws. The two male connectors are welded and the leads form a plug and are built into the follower block and locked by screws. Traditional technology causes the conversion switch to be large in size and complex in structure. In addition, the screws are easy to loosen after being hit during use, resulting in connector displacement, difficulty in inserting the pins, reduced switch reliability, and the overcurrent capacity of the pins is limited by the connector. In order to meet the higher performance requirements of circuit conversion, it is necessary to design a circuit conversion switch with a smaller size, higher reliability, and different overcurrent capabilities.

The insulating adhesive on the first socket base and the second socket base is bonded with conductive sockets with the same number as the T-shaped pins on the plug at one end thereof facing the plug, and is bonded with leads electrically connected to the conductive sockets.

[0008] The spring is coaxially sleeved on the guide rod;

[0009] The length of the T-shaped pin on the plug is smaller than the distance between the first socket and the second socket; when the T-shaped pin on the plug is inserted into the conductive socket on the first socket, the spring is compressed, and when the T-shaped pin on the plug is inserted into the conductive socket on the second socket, the spring is in a natural state.

[0010] Furthermore, the plug and the second socket are provided with a first notch and a second notch opposite to each other, and two ends of the spring are respectively located in the first notch of the plug and the second notch of the second socket;

DETAILED DESCRIPTION

[0031] The present invention is described in detail below with reference to the accompanying drawings and embodiments.

[0032] Reference Figures 1 to 11A multi-channel sliding switch includes a first socket base 18 and a second socket base 7 fixedly mounted at both ends of a guide rod 2, and:

[0033] Plug base 10: Slidingly connected with the guide rod 2, and located between the first socket base 18 and the second socket base 7; the plug base 10 is glued with an insulating adhesive 801 to form a plug 4, and at least two T-shaped pins 11 parallel to the length direction of the guide rod 2 and extending outward at both ends for connecting with the socket are glued on the insulating adhesive A801; the lead wire A1501 electrically connected to the T-shaped pin 11 is also glued on the insulating adhesive A801;

[0034] The first socket base 18 and the second socket base 7 are respectively bonded with insulating adhesive B802 and insulating adhesive C803, respectively constituting the first socket 5 and the second socket 1. The insulating adhesive B802 on the first socket base 18 and the insulating adhesive C803 on the second socket base 7 are respectively bonded with conductive sockets A901 and B902, which are the same in number as the T-shaped pins 11 on the plug 4, on one end facing the plug 4, and are respectively bonded with leads B1502 electrically connected to the conductive sockets A901 and leads C1503 electrically connected to the conductive sockets B902;

[0035] The spring 3 is coaxially sleeved on the guide rod 2;

[0036] The length of the T-shaped pin 11 on the plug 4 is smaller than the distance between the first socket 5 and the second socket 1; when the T-shaped pin 11 on the plug 4 is inserted into the conductive socket A901 on the first socket 5, the spring 3 is compressed, and when the T-shaped pin 11 on the plug 4 is inserted into the conductive socket B902 on the second socket 1, the spring 3 is in a natural state.

[0037] Thus, the present invention uses T-shaped pin 11 / conductive socket to be bonded in the plug base 10, instead of the traditional solution of threading the connector and the base, so that the T-shaped pin 11 / conductive socket will not loosen during repeated use, thereby improving reliability. Moreover, the plug 4 of the present invention uses T-shaped pin 11 to be bonded in the insulating glue body, and is provided with a lead wire electrically connected to the T-shaped pin 11 (the lead wire is electrically connected to the T-shaped pin 11 inside the insulating glue body of the plug 4) to form the plug 4, instead of the traditional solution of welding two male connectors and then forming a plug with leads, reducing the size of the plug 4, so that the switch can be applied to circuits with limited space, and the T-shaped pin 11 has the characteristics of strong current carrying capacity.

[0038] As an example, in this embodiment, the plug 4 is provided with a first notch 1301, the second socket 1 is provided with a second notch 1302 opposite to the first notch 1301, and the two ends of the spring 3 are respectively located in the first notch 1301 of the plug 4 and the second notch 1302 of the second socket 1; the end of the plug 4 facing the first socket 5 is also provided with a boss 12, and the first socket 5 is provided with a third notch 16 opposite to the boss 12. When the T-shaped pin 11 on the plug 4 is inserted into the conductive socket 901 on the first socket 1, the boss 12 is located in the third notch 16. In addition, referring to Fig.11 There are step structures 17 at both ends of the guide rod 2. The step structure 17 at one end of the guide rod 2 located at the first socket 5 abuts against the first notch 16 of the first socket 5, and the step structure 17 at one end of the guide rod 2 located at the second socket 1 abuts against the second notch 1302 of the second socket 1. This structural design makes the docking of the plug 4 and the socket more reliable and accurate.

[0039] Specifically, in this embodiment, both ends of the T-shaped pin 11 on the plug 4 are chamfered to facilitate insertion into the conductive jack of the first socket 5 or the second socket 1. In addition, a follower block 14 is provided on the bottom surface of the plug 4 for connecting with an external power mechanism to push the plug 4 to slide toward the first socket 5. Figure 1 to Figure 4 The first socket 5 and the second socket 1 are both fixedly mounted on the two ends of the guide rod 2 through nuts 6.

[0040] More specifically, in this embodiment, referring to Fig. 9 and Fig.10 For the first socket 5 and the second socket 1, the socket base is a rectangular parallelepiped with a cavity in the middle. The conductive sockets are arranged in the cavity of the socket base in a certain number and spacing. The conductive sockets and the socket base are glued and fixed by insulating glue. The first socket 5 and the second socket 1 are provided with mounting holes 19 for mounting and fixing. The spacing of the conductive sockets is determined by the insulation requirements of the T-shaped pins 11.

[0041] More specifically, refer to Figure 7 and Figure 8 For the plug 4, the T-shaped pin 11 is bonded with the insulating adhesive to form a component. The plug base 10 is a rectangular parallelepiped with a cavity in the middle.

[0042] In this embodiment, refer to Figure 1 , in the free state, the plug 4 is inserted into the first socket 5, at this time, the normally closed end of the circuit switch is closed, and the normally open end is disconnected, refer to Figure 3 , plug 4 is under the action of the external force of the external power mechanism, the compression spring 3 moves to one end of the second socket 1, at this time, the normally closed end of the circuit is disconnected, the normally open end is closed, and the conversion switch completes the conversion function. After the external force disappears, the plug 4 is reset to the position under the action of the elastic force of the spring 3. Figure 1 state.

[0043] In summary, the above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
