Description

Technical Field

[0001] The utility model relates to the technical field of plug-in printed circuit board connectors, in particular to a circuit board connector. Background Art

[0002] A printed circuit board connector, also known as a PCB connector, is a type of electronic connector that is specifically used to connect and fix the connectors on a printed circuit board. It is usually press-fit and has a strong FPC cable clamping force. For example, a 2EDG5.08mm plug-in PCB connector has a plug that is fixedly connected to a resilient plastic block, and the inner side of the end of the resilient plastic block protrudes outward in an arc shape. When the plug in the PCB connector is aligned with the socket in the socket of the PCB connector, the arc-shaped protrusion at the end of the resilient plastic block will bend and become stuck in the slot on the outer wall of the socket, thereby achieving the purpose of increasing the high damping connection between the socket and the plug.

[0003] However, the arc-shaped protrusion at the end of the elastic plastic block can only connect the socket and the plug with high damping, but does not fix the socket and the plug together. This article aims to propose a circuit board connector that prevents the plug from detaching. Utility Model Content

[0004] The utility model aims to solve the problem that the socket and the plug in the prior art are only connected with high damping but are not fixedly connected, and proposes a circuit board connector.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0006] A circuit board connector, comprising a socket and a plug, wherein the lower end of the second insulating shell in the plug and the inner cavity of the socket of the first insulating shell in the socket are mutually engaged, a straight plate is fixedly installed in parallel on one side of the second insulating shell through an elastic plastic sheet, the plastic sheet is arranged at the middle end of the side wall of the straight plate, and a bar is fixedly installed on the inner side of the lower end of the straight plate, and the cross section of the bar is a right triangle;

[0007] The side wall of the insulating shell 1 is provided with a slot corresponding to the inverted hook.

[0008] Preferably, the plug further comprises a plurality of corrugated connecting buckles, and the plurality of corrugated connecting buckles are respectively and detachably fixedly mounted in a plurality of limiting holes in the second insulating shell.

[0009] Preferably, a positioning block is coaxially fixedly installed on the top of the corrugated connecting buckle, a positioning groove is coaxially connected to the top of the limiting hole, a rotating hole is provided on one side of the positioning groove, the positioning block is slidably fitted in the positioning groove, a threaded hole connected to the rotating hole is provided on the positioning block, and a pressure-adjusting screw is installed in the mutually connected rotating hole and threaded hole.

[0010] Preferably, the positioning block is provided with a connecting hole interconnected with the threaded hole, and the insulating shell 2 is provided with a plurality of wire holes interconnected with the connecting hole, contacts are inserted in the wire holes, and the lower ends of the contacts are in contact with the voltage regulating screws in the connecting holes.

[0011] Preferably, the socket further comprises a plurality of solder pins, wherein the plurality of solder pins are respectively and vertically fixedly installed in the inner cavity of the socket, and a plurality of protrusions are respectively and fixedly installed on the bottom surface of the inner cavity of the socket, and the plurality of protrusions are respectively and fixedly installed on the periphery of the plurality of solder pins.

[0012] Preferably, a plurality of positioning blocks are fixedly connected to the inner walls on both sides of the inner cavity of the socket, and a plurality of sliding grooves that engage with the plurality of positioning blocks are arranged on the outer walls on both sides of the second insulating shell.

[0013] Compared with the prior art, the utility model provides a circuit board connector, which has the following beneficial effects:

[0014] 1. The circuit board connector is used to assist the plug in being quickly fixed and connected to the inner cavity of the socket in the socket through the corresponding engaging grooves on the socket and the plug and the inverted hook at the lower end of the straight plate. When the plug is vertically inserted into the inner cavity of the socket in the socket, the outer wall of the insulating shell one pushes the straight plate to rotate and deviate along the elastic plastic sheet through the inverted hook until the plug moves down to the lowermost end of the inner cavity of the socket. The inverted hook and the groove on the insulating shell one correspond to each other, and the elasticity of the elastic plastic sheet can drive the straight plate to reset and snap the inverted hook into the groove, thereby completing the fixed connection between the socket and the plug. The inverted hook hooks the groove, and the socket and the plug cannot be separated, which can effectively prevent the socket and the plug from accidentally separating. At the same time, to pull out the plug, it is only necessary to press the upper end of the straight plate close to the insulating shell two, so that the lower end of the straight plate can be deflected to the left with the elastic plastic sheet as the axis to separate from the groove, and the plug can be pulled out upward to separate the socket.

[0015] 2. The circuit board connector uses a plurality of voltage-adjusting screws to detachably fix a plurality of corrugated connectors on the insulating housing 2, so as to facilitate manual maintenance or replacement of the corrugated connectors. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0023] See attached Figure 1-4 A circuit board connector includes a socket 1 and a plug 2. The socket 1 is mainly composed of an insulating shell 101 and five welding pins 102. A socket 104 with an opening facing upward is arranged above the insulating shell 101. A plurality of positioning blocks 105 protruding outward are fixedly connected to the inner walls on both sides of the inner cavity of the socket 104. Five welding pins 102 are equidistantly and vertically fixedly installed in the inner cavity of the socket 104 in the socket 1. The lower end of the welding pin 102 passes downward through the lower bottom surface of the insulating shell 101. A plurality of protrusions 103 for reinforcing the welding pin 102 are fixedly connected to the inner bottom surface of the inner cavity of the socket 104. The five welding pins 102 are fixedly passed through the five protrusions 103 respectively.

[0024] In this embodiment, the plug 2 includes an insulating shell 201 and five corrugated connecting buckles 214. The outer walls on both sides of the lower end of the insulating shell 201 are symmetrically provided with a plurality of slide grooves 202 corresponding to the plurality of positioning blocks 105 on the inner wall of the socket 104, which are used to engage and connect the outer surface of the lower end of the insulating shell 201 with the inner cavity of the socket 104. The lower part of the insulating shell 201 is provided with five limiting holes 209 corresponding to the welding pins 102. The top ends of the five limiting holes 209 are coaxially connected with the positioning grooves 210. The top ends of the five positioning grooves 210 are coaxially connected with the wire holes 206. One side of the five limiting holes 209 is vertically connected with the rotating holes 208. The corrugated connecting buckle 214 is specifically composed of two elastic brass sheets symmetrically arranged in a corrugated manner. The welding pin 102 is also made of brass. The lower ends of the five welding pins 102 are fixedly welded to the circuit board. The spacing between the two elastic brass sheets in the corrugated connecting buckle 214 is less than the diameter of the welding pin 102. Figure 4 When the plug 2 is inserted into the socket 104 in the socket 1, the top ends of the five welding pins 102 will respectively press upwards the elastic brass sheets of two corrugations in the five corrugated connecting buckles 214 to deform and fit on both sides and press against the inner wall of the limiting hole 209, thereby completing the connection between the five welding pins 102 and the five corrugated connecting buckles 214 in the socket 1 and the plug 2;

[0025] The top of the corrugated connecting buckle 214 is fixedly connected with a positioning block 211, and the five positioning blocks 211 are respectively positioned and slidably installed in the five positioning grooves 210. A connecting hole 212 is provided in the positioning block 211, and the five connecting holes 212 are respectively connected to the five wire holes 206. A threaded hole 213 is vertically connected to one side of the connecting hole 212, and the five threaded holes 213 are respectively connected to the five rotating holes 208. A pressure regulating screw 207 is rotatably installed in the five rotating holes 208. The end of the pressure regulating screw 207 is threadedly connected to the threaded hole 213 on the positioning block 211. The connecting holes 212 in the five positioning blocks 211 are respectively fixedly connected with the contacts 205 through the five pressure regulating screws 207. Similarly, the five corrugated connecting buckles 21 4 is also detachably threadedly installed on the insulating housing 201 through five voltage-adjusting screws 207, which is convenient for maintenance or replacement of the corrugated connecting buckle 214. As is known to all, the high working temperature of the corrugated connecting buckle 214 will affect the hardness and elasticity of the elastic brass sheet. Therefore, after long-term use, the elasticity of the elastic brass sheet will decrease, and the welding pin 102 and the corrugated connecting buckle 214 will also be worn due to multiple plugging and unplugging, which will easily cause the welding pin 102 and the corrugated connecting buckle 214 to have poor contact, which requires timely inspection and maintenance. The contact 205 is specifically made of a brass wire connected to a wire, or a metal welding foot connected to a circuit board. The top ends of the five contacts 205 respectively penetrate upward through the five wire holes 206 on the insulating housing 201.

[0026] In this embodiment, a straight plate 203 is fixedly installed in parallel on one side of the insulating shell 201 in the plug 2 through an elastic plastic sheet 204. The elastic plastic sheet 204 has a certain elasticity and can be bent within a preset range. The elastic plastic sheet 204 is vertically fixedly installed on the middle end of the straight plate 203. A barb 215 is provided on the inner side below the straight plate 203. The cross-section of the barb 215 is a right-angled triangle. The insulating shell 101 in the socket 1 is provided with a card groove 106 that is mutually engaged with the barb 215. When the plug 2 is vertically inserted into the inner cavity of the socket 104 in the socket 1, the barb 215 hooks the card groove 106, and the socket 1 and the plug 2 cannot be separated, which can effectively prevent the socket and the plug from being accidentally separated. The outer wall of the shell 101 pushes the straight plate 203 to rotate and deviate along the elastic plastic sheet 204 through the inverted hook 215 until the plug 2 moves down to the lowermost end of the inner cavity of the socket 104. The inverted hook 215 and the card slot 106 on the insulating shell 101 correspond to each other. The elasticity of the elastic plastic sheet 204 can drive the straight plate 203 to reset and snap the inverted hook 215 into the card slot 106, thereby completing the fixed connection between the socket 1 and the plug 2. When the socket 1 and the plug 2 need to be separated, it is only necessary to press the upper end of the straight plate 203 close to the insulating shell 201. The lower end of the straight plate 203 can be deflected to the left with the elastic plastic sheet 204 as the axis to disengage from the card slot 106, and the plug 2 can be pulled out upward to separate the socket 1.

[0027] The utility model uses a plurality of positioning blocks 105 and a plurality of slide grooves 202 on the socket 1 and the plug 2 to assist manual alignment and connection of the socket 1 and the plug 2, and then uses the card slots 106 on the socket 1 and the plug 2 and the hook 215 at the lower end of the straight plate 203 to assist the plug 2 to be quickly fixed and connected to the inner cavity of the socket 104 in the socket 1, and uses the lever principle, and only needs to press the upper end of the straight plate 203 close to the insulating shell 201, and the lower end of the straight plate 203 can be deflected to the left with the elastic plastic sheet 204 as the axis, and disengage from the card slot 106, so that the plug 2 can be pulled out upward to separate the socket 1.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
