Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1 to 4, a four-core connection terminal comprises a cylindrical explosion-proof shell 1, an insulating base 2 and connection posts 3, wherein the insulating base 2 is fixed in the cylindrical explosion-proof shell 1, threads are arranged outside the cylindrical explosion-proof shell 1, two ends of the insulating base 2 respectively extend to the outside of the cylindrical explosion-proof shell 1, four connection posts 3 are fixed in the insulating base 2, and two ends of the connection posts 3 respectively extend to the outside of the insulating base 2.
Wherein, the one end of insulating base member 2 is provided with step 4, and the other end is provided with four lower wiring grooves 5, and the top and the bottom of step 4 all are provided with two and go up wiring groove 6, and the both ends of four terminals 3 are located corresponding last wiring groove 6 and lower wiring groove 5 respectively.
The utility model discloses a fix insulating base in cartridge type flame proof casing, the terminal is installed in insulating base, makes to separate between the terminal to it is insulating, and the insulating base both ends set up wiring groove and lower wiring groove, makes the both ends of terminal also separate with other terminals like this, and it is more convenient to work a telephone switchboard, and the cable is mutual noninterference, and it is more reliable convenient to work a telephone switchboard.
In addition, the insulating base body 2 is formed by die casting melamine asbestos filler, a fixing groove 7 is arranged in the cylindrical explosion-proof shell 1, and a positioning groove 8 is arranged on the outer wall of the binding post 3. The insulating base body is formed by melamine asbestos filler, the binding post and the cylindrical explosion-proof shell in an integrated die-casting mode, the structural strength is high, and the fixing groove 7 and the positioning groove 8 can ensure that the cylindrical explosion-proof shell, the binding post and the insulating base body are combined together and are not prone to falling off.
The foregoing is considered as illustrative and not restrictive of the preferred embodiments of the invention, and any modifications, equivalents and improvements made within the spirit and principles of the invention are intended to be included within the scope of the invention.
