[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0027] A universal debugging device for a fire alarm controller, such as Figure 1-Figure 3As shown, it includes a male head 1 and a female head 2, both of which are convex blocks and hollow inside. A front plug 3 is fixedly installed on the front end surface of the male head 1, and male through grooves 4 are evenly opened on the front plug 3. The male through grooves 4 are communicated with the inside of the male head 1. A plurality of groups of male contact pieces 5 are evenly fixedly installed on the end surface of the front plug 3 corresponding to the inside of the male head 1, and each male contact piece 5 corresponds to the bottom of a male through groove 4. A pin 6 is slidably installed in the male contact piece 5, and the pin 6 can pass through the male through groove 4 to the front end of the front plug 3. In particular, the pin 6 is fixedly connected to the push plate component. Correspondingly, the front end surface of the female head 2 is evenly opened with female through grooves 10 The female insertion groove 10 corresponds to the male insertion groove 4 one by one, and a female contact piece 11 is fixedly installed at the position corresponding to the female insertion groove 10 inside the female head 2. The male contact piece 5 and the female contact piece 11 are both made of metal conductive material, and the pin 6 is also made of metal conductive material. When debugging is required, the push plate component pushes multiple pins 6 out of the male head 1, so that the pin 6 passes through the male insertion groove 4 and enters the female insertion groove 10, and is electrically connected to the female contact piece 11. When not debugging, the push plate component pulls multiple pins 6 from the outside of the male head 1 into the inside of the male head 1, so that the pin 6 is protected by the male head 1 to prevent the pin 6 from being deformed, bent or broken.
[0028] Furthermore, the male contact piece 5 is a rectangular metal strip with an arc-shaped groove on the top surface. The pin 6 fits tightly with the arc-shaped groove of the male contact piece 5 and a part of the pin 6 is always located in the male through groove 4. The male contact piece 5 is connected to the wire outside the connector, so that no matter how the pin 6 slides during the sliding process, it will not deviate from the position and is always conductive.
[0029] Furthermore, the push plate component includes a card block 7, a connecting frame 8 and a slider 9, wherein the card block 7 is made of plastic material and is clamped at one end of the pin 6, and the connecting frame 8 is connected between adjacent card blocks 7 so that multiple card blocks 7 can move synchronously. An avoidance groove 15 is opened on the side of the male head 1, and the slider 9 is slidably installed in the avoidance groove 15 and can slide along the length direction of the avoidance groove 15. One end of the slider 9 is fixedly connected to the connecting frame 8, and the other end extends to the upper end of the male head 1, so that the slider 9 is used to control the multiple card blocks 7, and indirectly control the multiple pins 6 to slide in and out synchronously.
[0030] Furthermore, the slider 9 extends to the end surface of the upper end of the male head 1 and extends circumferentially to form a rectangular plate, and an anti-slip groove is provided on the top of the rectangular plate to increase friction and controllability.
[0031] Furthermore, the slider 9 is integrally formed with a lower limit plate 17 at the position corresponding to the top of the inner wall of the male head 1. The lower limit plate 17 cooperates with the top of the slider 9, so that the slider 9 cannot shake at will and can only slide along the length direction of the avoidance groove 15, further improving the control performance.
[0032] In a preferred embodiment, two sets of interference fit sealing pads 16 are fixedly installed on opposite sides of the avoidance groove 15. The sealing pads 16 are made of sponge material and wrap the slider 9, so that the inside of the male head 1 is isolated from the outside, playing a dust-proof role without affecting the sliding of the slider 9.
[0033] In a preferred embodiment, the front end surface of the female connector 2 is recessed inward to form a slot 12, and the front end surface of the front connector 3 protrudes outward to form a mating block 13. The slot 12 and the mating block 13 cooperate with each other to reduce the shaking when the male connector 1 and the female connector 2 are plugged in.
[0034] In other embodiments, a fool-proofing portion 14 is provided on one side of the bottom end of the mating block 13, and a protrusion corresponding to the fool-proofing portion 14 is provided in the corresponding slot 12, so that the directions of the male connector 1 and the female connector 2 will not be mistaken when they are plugged in.
[0035] In other embodiments, in order to prevent dust and debris from falling into the female threading slot 10 and affecting the electrical contact, a dust-proof plug 18 can be detachably installed in the slot 12, and the dust-proof plug 18 is made of rubber.
[0036] In other embodiments, corresponding screw holes 19 are provided on both sides of the male head 1 and the female head 2. When the male head 1 and the female head 2 are connected, screws and other parts can be used to tightly connect the male head 1 and the female head 2 to avoid separation during debugging and cause system errors.
[0037] The working principle of the utility model is as follows: through the space opened in the male head 1 and the male groove 4 opened on the front end face of the male head 1 and communicating with the inside of the male head 1, the pin 6 is hidden inside the male head 1 when not in use. When in use, it is pushed out from the male groove 4 to connect with the female head 2, which plays a role in protecting the pin 6. At the same time, in order to make multiple pins 6 slide out and in synchronously, the rear end face of the pin 6 is clamped with a clamping block 7, a connecting frame 8 and a sliding block 9, which is convenient for unified control of the sliding in and out of the pin 6.
[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
