[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention discloses a surface mount connector assembly based on an improved pin structure. Through the arrangement of a first elastic block, a second elastic block, a fourth elastic block and a fifth elastic block, a current terminal moves upward from the lower side of a card slot into an insulating shell, and the first limiting portion moves upward to drive the slider to move upward in the card slot; the upper side of the first elastic block slides in contact with the lower side of the fifth elastic block and the lower side inclined surface of the fourth elastic block, respectively, and the upper side of the second elastic block slides in contact with the lower side of the fifth elastic block and the lower side inclined surface of the fourth elastic block, respectively, so that the slider moves upward smoothly in the card slot; and then the inclined lower end of the first elastic block contacts the inclined upper end of the fifth elastic block and the inclined upper end plane of the fourth elastic block, respectively, and the inclined lower end of the second elastic block contacts the inclined upper end of the fifth elastic block and the inclined upper end plane of the fourth elastic block, respectively, so that the downward movement of the slider is limited, so that the current terminal moves upward smoothly and is limited and fixed in the card slot. By setting the first spring, the fixed block, the third elastic member, the third elastic block and the second elastic member, the slider moves downward in the slide groove, and when the inclined lower end of the first elastic block contacts the inclined upper end of the fourth elastic block, the first elastic member and the fixed block support the first elastic block, and the third elastic member and the fifth elastic block support the fourth elastic block, and the third elastic block and the second elastic member support the fourth elastic block and the fifth elastic block, so that the first limiting assembly and the second limiting assembly can be used to limit and fix the slider downward, so as to prevent the current terminal from moving arbitrarily in the slot. Finally, through the setting of the second hollow elastic member and the sliding rod, the sliding block moves upward to drive the first limiting assembly to move upward, and the fixed block moves upward to make the upper side of the second hollow elastic member contact with the upper side of the sliding groove, thereby extruding and deforming the second hollow elastic member to squeeze the solution in the second hollow elastic member into the fixed block, and the solution in the fixed block pushes the sliding rod and the movable block to move obliquely upward, and the movable block moves obliquely upward to drive the second elastic block to move upward, thereby increasing the contact area between the inclined lower end of the second elastic block and the inclined upper end of the fourth elastic block or the inclined upper end of the fifth elastic block, which is beneficial to improve the limiting and fixing effect between the first limiting assembly and the second limiting assembly, so that the current terminal can be quickly and smoothly welded and fixed in the slot.

[0017] The present invention discloses a surface mount connector component based on an improved pin structure. Through the setting of a first slide plate, the upward movement of the slide plate drives the first limit component to move upward. A plurality of second limit components are distributed at intervals along the inclined surface of one side of the first slide plate, and the distance between one side of the first slide plate and the slide plate gradually narrows from bottom to top, so that the contact area between the first limit component and the plurality of second limit components increases continuously when the first limit component moves upward, which is beneficial to promoting the smooth upward movement of the current terminal in the slot, and improving the limiting and fixing effect of the plurality of second limit components on the first limit component, which is beneficial to limiting and fixing the current terminal in the slot. Then, through the setting of the first hollow elastic part, the slider moves upward and contacts the lower end of the first push rod. The slider moves upward to push the first push rod and the piston plate to move upward. The piston plate moves upward to allow a portion of the solution in the hydraulic chamber to enter the first hollow elastic part through the first connecting channel, so that the first hollow elastic part expands and pushes the first slide plate to move. The movement of the first slide plate drives several second limit assemblies to approach the first limit assembly, thereby further increasing the contact area between the first limit assembly and the second limit assembly, so as to limit and fix the current terminal in the slot, thereby improving the efficiency of welding and fixing the current terminal in the slot.

[0018] The present invention discloses a surface mount connector assembly based on an improved pin structure. Through the arrangement of a movable frame, a clamping plate, and a first rubber plate, the piston plate moves upward to allow another part of the solution in the hydraulic chamber to enter the inner middle of the frame through the second connecting channel. The solution pushes the two movable frames to move away from each other up and down. Through one end of the clamping plate, it is rotationally connected to one side of the second slide plate. The middle part of the clamping plate is rotationally connected to the opening. The two movable frames move away from each other up and down, driving the two second slide plates to move away from each other up and down, thereby causing the two clamping plates to rotate around the two rotating axes respectively. The rotation of the two clamping plates drives the two first rubber plates to move closer to each other to clamp and fix the upper and lower sides of the second limiting portion. The second limit stopper is configured to allow the two clamping plates to rotate relative to each other around the two rotating shafts, so that the two second slide plates slide horizontally in the two movable frames respectively. The second slide plate moves to allow the solution in the movable frame to enter the fixed seat through the telescopic connecting tube. The solution in the fixed seat pushes the second push rod and the second rubber plate to move. The second rubber plate moves to contact one side of the second limit portion and cooperates with the other side of the second limit portion to contact the second limit block, thereby clamping and fixing both sides of the second limit portion, so as to facilitate clamping and fixing the second limit portion in multiple directions, which is beneficial to clamping and fixing the current terminal in the slot, and is beneficial to improving the quality of welding and fixing the current terminal in the slot.

[0037] Specific use of the present invention: In terms of usage, during the product welding process, the solder paste needs to flow evenly along the shape of the pin after it melts, so the uniformity of the solder during the flow process is relatively important, but it is inevitable that too much solder paste will occur. However, there is a chamfer 17 on the upper side of one end of the pin portion 57, and the chamfer 17 is used to drain the solder paste, thereby reducing the solder residue on the upper side of the pin portion 57, avoiding the situation where two adjacent pin portions 57 are welded together, and reducing the probability of connecting the pins. From the perspective of maintainability, when there are quality problems with the solder joints of the product that has been welded by reflow soldering, or there is too much solder or too little solder, it is necessary to manually repair the connector solder joints from the cost point of view, and manually use an electric soldering iron to add or remove tin. The chamfered pins are faster to add or remove tin than the right-angled pins, and are more convenient to handle. It is smoother when pulling the soldering iron. The right-angled pins will produce greater resistance, so the pins with chamfers are more convenient for operators to repair.

[0038] In the assembly method, first, the staff installs and fixes the shielding sheet 13 in the long strip groove 12, and moves the current terminal 16 upward from the lower side of the card slot 15 into the insulating housing 10, and the first limiter 56 moves upward to drive the slider 19 to move upward in the slide groove 59. The upper side of the first elastic block 29 slides in contact with the lower side of the fifth elastic block 35 and the lower side of the fourth elastic block 34, and the upper side of the second elastic block 30 slides in contact with the lower side of the fifth elastic block 35 and the lower side of the fourth elastic block 34, so that the slider 19 moves upward smoothly in the slide groove 59. Then, the inclined lower end of the first elastic block 29 is in plane contact with the inclined upper end of the fifth elastic block 35 and the inclined upper end of the fourth elastic block 34, and the inclined lower end of the second elastic block 30 is in plane contact with the inclined upper end of the fifth elastic block 35 and the inclined upper end of the fourth elastic block 34, so as to limit the downward movement of the slider 19, so as to make the current terminal 16 move upward smoothly and be fixed in the slot 15. When the slider 19 moves downward in the slide slot 59 and the inclined lower end of the first elastic block 29 is in plane contact with the inclined upper end of the fourth elastic block 34, the first elastic member 31 and the fixed block 24 support the first elastic block 29, and the third elastic member 36 and the fifth elastic block 35 support the fourth elastic block 34. The third elastic block 32 and the second elastic member 33 support the fourth elastic block 34 and the fifth elastic block 35, so that the first limiting assembly 22 and the second limiting assembly 23 can be used to limit and fix the slider 19 downward, thereby preventing the current terminal 16 from moving arbitrarily in the slot 15. One side of the first limiting portion 56 is limited by the contact between the first limiting assembly 22 and the second limiting assembly 23, and the other side of the first limiting portion 56 is limited by the first limiting block 18, so that the first limiting portion 56 is centered in the slot 15.

[0039] Secondly, the upward movement of the slider 19 drives the first position-limiting assembly 22 to move upward, and the upward movement of the fixed block 24 causes the upper side of the second hollow elastic member 27 to contact the upper side of the slide groove 59, thereby squeezing the second hollow elastic member 27. The second hollow elastic member 27 is squeezed and deformed, and the solution in the second hollow elastic member 27 is squeezed into the fixed block 24. The solution in the fixed block 24 pushes the slide bar 25 and the movable block 26 to move upward obliquely. The movable block 26 moves upward obliquely and drives the second elastic block 30 to move upward, thereby increasing the contact area between the inclined lower end of the second elastic block 30 and the inclined upper end of the fourth elastic block 34 or the inclined upper end of the fifth elastic block 35, which is beneficial to improving the position-limiting and fixing effect between the first position-limiting assembly 22 and the second position-limiting assembly 23, so that the current terminal 16 can be quickly and smoothly welded and fixed in the slot 15. Among them, the upward movement of the slide bar 25 stretches the first spring 28 to generate elastic force, so that under the elastic force of the first spring 28, the slide bar 25 can be moved downward obliquely to reset.

[0040] Next, the slider 19 moves upward to drive the first limit assembly 22 to move upward, and a plurality of second limit assemblies 23 are distributed at intervals along the inclined surface of one side of the first slide plate 21, and the distance between one side of the first slide plate 21 and the slider 19 gradually narrows from bottom to top, so that the contact area between the first limit assembly 22 and the plurality of second limit assemblies 23 when the first limit assembly 22 moves upward is continuously increased, which is conducive to promoting the current terminal 16 to move upward smoothly in the slot 15, and improving the limiting and fixing effect of the plurality of second limit assemblies 23 on the first limit assembly 22, which is conducive to limiting and fixing the current terminal 16 in the slot 15.

[0041] Then, the slider 19 moves upward and contacts the lower end of the first push rod 39. The slider 19 moves upward to push the first push rod 39 and the piston plate 38 to move upward. The piston plate 38 moves upward to allow a portion of the solution in the hydraulic chamber 37 to enter the first hollow elastic member 20 through the first connecting channel 41, so that the first hollow elastic member 20 expands and pushes the first slide plate 21 to move. The movement of the first slide plate 21 drives several second limiting assemblies 23 to approach the first limiting assemblies 22, thereby further increasing the contact area between the first limiting assemblies 22 and the second limiting assemblies 23, so as to limit and fix the current terminal 16 in the slot 15, thereby improving the efficiency of welding and fixing the current terminal 16 in the slot 15.

[0042] At the same time, the piston plate 38 moves upward to drive another part of the solution in the hydraulic chamber 37 into the middle of the frame body 43 through the second connecting channel 42. The solution pushes the two movable frames 44 to move away from each other up and down. Through one end of the clamping plate 47 and the rotational connection with one side of the second slide plate 45, the middle part of the clamping plate 47 is rotated and connected with the opening 46. The two movable frames 44 move away from each other up and down, driving the two second slide plates 45 to move away from each other up and down, so that the two clamping plates 47 rotate around the two rotating shafts 60 respectively. The two clamping plates 47 rotate and drive the two first rubber plates 48 to move closer to each other to clamp and fix the upper and lower sides of the second limiter 58. Among them, the two movable frames 44 move away from each other up and down to compress the two third springs 49 to generate elastic force, so that under the elastic force of the two third springs 49, the two movable frames 44 can move closer to each other up and down to reset.

[0043] At the same time, the two clamping plates 47 rotate relative to each other around the two rotating shafts 60, so that the two second slide plates 45 slide horizontally in the two movable frames 44, respectively. The second slide plates 45 move to allow the solution in the movable frame 44 to enter the fixed seat 51 through the telescopic connecting tube 54. The solution in the fixed seat 51 pushes the second push rod 52 and the second rubber plate 55 to move. The second rubber plate 55 moves to contact one side of the second limiting portion 58 and cooperate with the other side of the second limiting portion 58 to contact the second limiting block 50, thereby clamping and fixing the two sides of the second limiting portion 58, so as to facilitate clamping and fixing the second limiting portion 58 in multiple directions, which is beneficial to clamping and fixing the current terminal 16 in the slot 15, and is beneficial to improving the quality of welding and fixing the current terminal 16 in the slot 15.

[0044] Finally, after the current terminal 16 is fully limited and fixed in the slot 15 , the staff welds the current terminal 16 and the protrusion 11 to fix them.

[0045] In a surface mount connector assembly based on an improved pin structure of the present invention, through the arrangement of the first elastic block 29, the second elastic block 30, the fourth elastic block 34, and the fifth elastic block 35, the current terminal 16 moves upward from the lower side of the card slot 15 into the insulating housing 10, and the first limit portion 56 moves upward to drive the slider 19 to move upward in the slide slot 59; the upper side of the first elastic block 29 is in sliding contact with the lower side of the fifth elastic block 35 and the lower side inclined surface of the fourth elastic block 34, and the upper side of the second elastic block 30 is in sliding contact with the lower side of the fifth elastic block 35 and the lower side inclined surface of the fourth elastic block 34, respectively. 5 and the lower inclined surface of the fourth elastic block 34, so that the slider 19 moves smoothly upward in the slide groove 59; then the inclined lower end of the first elastic block 29 is in plane contact with the inclined upper end of the fifth elastic block 35 and the inclined upper end of the fourth elastic block 34, and the inclined lower end of the second elastic block 30 is in plane contact with the inclined upper end of the fifth elastic block 35 and the inclined upper end of the fourth elastic block 34, so as to limit the downward movement of the slider 19, so that the current terminal 16 can move smoothly upward and be limited and fixed in the card slot 15. By setting the first spring 28, the fixed block 24, the third elastic member 36, the third elastic block 32, and the second elastic member 33, the slider 19 moves downward in the slide groove 59. When the inclined lower end of the first elastic block 29 contacts the inclined upper end of the fourth elastic block 34, the first elastic member 31 and the fixed block 24 support the first elastic block 29, and the third elastic member 36 and the fifth elastic block 35 support the fourth elastic block 34, and the third elastic block 32 and the second elastic member 33 support the fourth elastic block 34 and the fifth elastic block 35, so that the first limiting assembly 22 and the second limiting assembly 23 can be used to limit and fix the slider 19 downward, so as to prevent the current terminal 16 from moving arbitrarily in the slot 15. Finally, through the arrangement of the second hollow elastic member 27 and the slide bar 25, the slider 19 moves upward to drive the first limit assembly 22 to move upward, and the fixed block 24 moves upward to make the upper side of the second hollow elastic member 27 contact with the upper side of the slide groove 59, thereby extruding and deforming the second hollow elastic member 27 to squeeze the solution in the second hollow elastic member 27 into the fixed block 24, and the solution in the fixed block 24 pushes the slide bar 25 and the movable block 26 to move obliquely upward, and the movable block 26 moves obliquely upward to drive the second elastic block 30 to move upward, thereby increasing the contact area between the inclined lower end of the second elastic block 30 and the inclined upper end of the fourth elastic block 34 or the inclined upper end of the fifth elastic block 35, which is beneficial to improve the limiting and fixing effect between the first limit assembly 22 and the second limit assembly 23, so that the current terminal 16 can be quickly and smoothly welded and fixed in the slot 15.

[0046] The present invention provides a surface mount connector assembly based on an improved pin structure. Through the setting of the first slide plate 21, the upward movement of the slide block 19 drives the first limit assembly 22 to move upward. A plurality of second limit assemblies 23 are distributed at intervals along the inclined surface of one side of the first slide plate 21, and the distance between one side of the first slide plate 21 and the slide block 19 gradually narrows from bottom to top, so that the contact area between the first limit assembly 22 and the plurality of second limit assemblies 23 when it moves upward is continuously increased, which is beneficial to promoting the current terminal 16 to move upward smoothly in the slot 15, and improving the limiting and fixing effect of the plurality of second limit assemblies 23 on the first limit assembly 22, which is beneficial to limiting and fixing the current terminal 16 in the slot 15. Through the setting of the first hollow elastic member 20, the slider 19 moves upward and contacts the lower end of the first push rod 39. The slider 19 moves upward to push the first push rod 39 and the piston plate 38 to move upward. The piston plate 38 moves upward to allow a portion of the solution in the hydraulic chamber 37 to enter the first hollow elastic member 20 through the first connecting channel 41, so that the first hollow elastic member 20 expands and pushes the first slide plate 21 to move. The movement of the first slide plate 21 drives several second limiting assemblies 23 to approach the first limiting assemblies 22, thereby further increasing the contact area between the first limiting assemblies 22 and the second limiting assemblies 23, so as to limit and fix the current terminal 16 in the slot 15, thereby improving the efficiency of welding and fixing the current terminal 16 in the slot 15.

[0047] The present invention provides a surface mount connector assembly based on an improved pin structure. Through the arrangement of a movable frame 44, a clamping plate 47, and a first rubber plate 48, the piston plate 38 moves upward to allow another part of the solution in the hydraulic chamber 37 to enter the middle of the frame body 43 through the second connecting channel 42. The solution pushes the two movable frames 44 to move away from each other up and down. Through one end of the clamping plate 47, it is rotatably connected to one side of the second slide plate 45. The middle part of the clamping plate 47 is rotatably connected to the opening 46. The two movable frames 44 move away from each other up and down, driving the two second slide plates 45 to move away from each other up and down, so that the two clamping plates 47 rotate relative to each other around the two rotating shafts 60 respectively. The rotation of the two clamping plates 47 drives the two first rubber plates 48 to approach each other to clamp and fix the upper and lower sides of the second limiting portion 58. By means of the arrangement of the fixing seat 51, the second push rod 52, the second rubber plate 55 and the second limiting block 50, the two clamping plates 47 rotate relative to each other around the two rotating shafts 60, so that the two second slide plates 45 slide horizontally in the two movable frames 44, respectively. The second slide plate 45 moves to allow the solution in the movable frame 44 to enter the fixing seat 51 through the telescopic connecting tube 54. The solution in the fixing seat 51 pushes the second push rod 52 and the second rubber plate 55 to move. The second rubber plate 55 moves to contact one side of the second limiting portion 58 and cooperates with the other side of the second limiting portion 58 to contact the second limiting block 50, thereby clamping and fixing the two sides of the second limiting portion 58, so as to facilitate clamping and fixing the second limiting portion 58 in multiple directions, which is beneficial for clamping and fixing the current terminal 16 in the slot 15, and is beneficial for improving the quality of welding and fixing the current terminal 16 in the slot 15.
