Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical auxiliary components technology, and in particular to a serial port male connector with anti-slip studs. Background Technology
[0002] In electronic devices, male serial port connectors are directly fixed to the equipment using studs. The base plate of the male serial port connector has through holes, through which the stepped studs press the base plate firmly against the equipment. When connecting a female serial port connector to the male connector, the screws on both sides of the female connector are then tightened into the through holes on the studs to secure it.
[0003] When used repeatedly, slippage may occur at the fixing position of the stud and the equipment. When tightening the screws on both sides of the female head, the stud rotates along with it, making it impossible to tightly fit the female head and the male head. As a result, the pin on the female head cannot achieve an effective electrical connection with the pin inside the male head, causing a loose connection and affecting the normal operation of the equipment. Utility Model Content
[0004] The purpose of this invention is to solve the above problems by providing a serial port male connector with anti-slip studs. The studs are fixed by engaging with the polygonal through holes at both ends of the base plate of the main body through the middle layer of the polygonal structure, which prevents the studs from rotating and slipping, and ensures a firm connection between the serial port female connector and the male connector interface.
[0005] The technical solution adopted by this utility model is:
[0006] A serial port male connector with anti-slip studs is characterized by comprising a body, a connector block, and a stud. The body includes an accommodating space and a base plate. The connector block is disposed within the accommodating space. The base plate of the body has polygonal through holes at both ends. The stud is hollow, with a rounded front end for insertion and fixation to a connecting device. The middle layer has a polygonal structure corresponding to the polygonal through holes on the base plate. The rear end is cylindrical, with the cylindrical dimension larger than the polygonal through holes at both ends of the base plate. When the rounded front end of the stud is fixed to the device, the middle layer mates with the polygonal through holes to fix the body to the device.
[0007] Furthermore, the polygon is one of an equilateral triangle, a square, or a regular hexagon.
[0008] Furthermore, the accommodating space and the base plate on the main body are integrally formed.
[0009] Furthermore, the thickness of the intermediate layer is 1.5 to 3 times the thickness of the base plate.
[0010] Furthermore, the protruding outer end of the accommodating space forms an inward flange, and the insertion block is tightly fitted and fixed to the accommodating space.
[0011] The beneficial effects of this utility model are:
[0012] (1) The polygonal through hole of the base plate is fixed to the middle layer of the stud so that the stud will not rotate and slip when the female head is inserted into the screw.
[0013] (2) The problem can be solved by simply replacing the studs without changing the original structure of the serial port male connector. Attached Figure Description

[0024] The following detailed description, in conjunction with the accompanying drawings, illustrates the specific implementation of a serial port male connector with anti-slip studs according to this utility model.
[0025] See appendix Figures 1 to 3 The serial port male connector 1 of this patent includes a main body 2, a connector block 3, and a stud 4. The connector block 3 is fixedly installed in the accommodating space 5 of the main body 2. The connector block 3 is provided with a connector pin hole and is connected to the device through the connecting wire below. The accommodating space 5 and the base plate 6 on the main body 2 are integrally formed. The protruding outer end of the accommodating space 5 forms an inward flange 7. The connector block 3 is tightly fitted and fixed to the accommodating space 5.
[0026] Polygonal through holes 8 are provided at both ends of the base plate 6 of the main body 2. The shapes of the polygonal through holes 8 are mainly equilateral triangles, squares, and regular hexagons. The stud 4 is hollow and threaded for screw fixing to the female head. The front end of the stud 4 is a round head 9, which is used to insert and fix it to the connecting device. The round head 9 is generally fixed to the device by riveting. Because the joint is generally fixed to the mounting plate of the device, such as the computer casing, the mounting plate is relatively thin and cannot be connected by threaded fastening. Therefore, the riveted structure is prone to rotation after long-term use.
[0027] The middle layer 10 above the circular head 9 of the stud 4 has a polygonal structure, which corresponds to the polygonal through hole 8 on the base plate 6. The thickness of the middle layer 10 should be 1.5 to 3 times the thickness of the base plate 6. If it is too small, it will not be able to connect with the polygonal through hole 8. If it is too large, the main body 2 will easily become loose.
[0028] The rear end of the stud 4 is a column 11. The cross-sectional dimension of the column 11 is larger than the cross-sectional dimension of the polygonal through holes 8 at both ends of the base plate 6. When the front end circular head 9 of the stud 4 is fixed on the equipment, the middle layer 10 cooperates with the polygonal through holes 8, and the rear end column 11 presses the base plate 6 of the main body 2 tightly on the equipment.
[0029] After the stud 4 fixes the male serial connector 1 to the equipment, the intermediate layer 10 engages with the polygonal hole, restricting the rotation of the stud 4. At this time, if the round head 9 at the front end of the stud 4 slips off from the equipment, when the female serial connector is inserted into the male connector 1 and screwed into the intermediate hole of the stud 4, no rotation will occur because the intermediate layer 10 of the stud 4 engages with the polygonal hole on the base plate 6, thus ensuring a smooth connection between the male and female serial connectors and the circuit.
[0030] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make several improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
