Description

Technical Field

[0001] This utility model relates to a plug connector. Background Technology

[0002] The MCIO (Mini Cool Edge IO) plug connector has a forward-protruding tongue plate with several conductive terminals for electrical connection with the mating terminals. The conductive terminals contact the flexible mating terminals of the connector to form an electrical connection. However, the tongue plate may abut against the mating terminals of the connector and cause damage under improper insertion or extraction force.

[0003] In view of this, it is necessary to improve the existing plug connectors to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a plug connector that can effectively avoid misaligned insertion.

[0005] To achieve the above-mentioned utility model objectives, this utility model provides a plug connector, which includes an insulating body, a tongue plate fixed to the insulating body, and a plurality of conductive terminals disposed on the tongue plate. The insulating body has a base portion and a plug plate protruding forward from the base portion. The tongue plate is disposed parallel to the plug plate. The insulating body also has a pair of side baffles disposed opposite to each other in the transverse direction, and a first top baffle and a second top baffle disposed at intervals in the transverse direction. The first top baffle and the second top baffle are both located on the upper side of the plug plate. Each of the side baffles extends in the vertical direction and extends upward beyond the upper surface of the plug plate. The side edges of each side baffle adjacent to the plug plate are spaced apart in the transverse direction to form a plugging space.

[0006] As a further improvement of this utility model, the plug plate extends forward beyond the front end face of the tongue plate, and the side baffle extends forward beyond the front end face of the tongue plate.

[0007] As a further improvement of this utility model, the side baffle and the first and second top baffles all extend forward beyond the front end face of the plug-in plate.

[0008] As a further improvement of this utility model, the first top baffle and its adjacent side baffle are integrally connected in an L-shape, and a slot is formed between the second top baffle and its adjacent side baffle, the slot being open to the front.

[0009] As a further improvement of this utility model, the upper surface of the second top baffle is inclined with the outer side higher than the inner side.

[0010] As a further improvement of this utility model, the insulating body also has a pair of bottom baffles that are respectively connected to the bottom ends of the pair of side baffles. The pair of bottom baffles are located on the lower side of the tongue plate and are spaced apart from the tongue plate in the height direction.

[0011] As a further improvement of this utility model, the pair of bottom baffles are spaced apart in the lateral direction, and each bottom baffle has a free end that approaches the other bottom baffle in the lateral direction, and the free end is located within the extension range of the tongue plate in the lateral direction.

[0012] As a further improvement of this utility model, in the height direction, the height difference between the bottom baffle and the tongue plate is greater than the height difference between the plug plate and the tongue plate.

[0013] As a further improvement of this utility model, the plug connector also has a locking member, which has a fixing part fixed to the plug plate and an elastic part formed by bending backward from the front end of the fixing part. The elastic part has a locking protrusion for locking with the mating socket connector.

[0014] As a further improvement of this utility model, the locking member also has a connecting part that connects the fixing part and the elastic part. The plug plate is provided with a pair of limiting grooves that are open upward and a fixing groove that communicates with the limiting grooves. The fixing part is fixed in the fixing groove and the connecting part is received in the limiting groove.

[0015] This utility model plug connector features side baffles that extend vertically and upwards beyond the upper surface of the plug plate. Each side baffle and the adjacent side edge of the plug plate are spaced laterally to form a plugging space. This plugging space defines the plugging path of the connector, guiding it to the correct lateral orientation and preventing lateral offset or wobbling. This ensures precise contact between the conductive terminals and the mating terminals, reducing wear, deformation, or poor contact caused by misalignment. Furthermore, by extending the side baffles upwards beyond the upper surface of the plug plate, they work in conjunction with the first and second top baffles to create a blocking effect above the plug plate, effectively preventing misaligned insertion and protecting the mating terminals and tongue from damage caused by incorrect operation.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Please refer to Figures 1 to 7 The diagram shows a first embodiment of the plug connector 100 of this utility model. In this embodiment, the plug connector 100 is an MCIO (Mini Cool Edge IO) plug connector. The plug connector 100 includes an insulating body 1, a tongue plate 2 fixed to the insulating body 1, and a plurality of conductive terminals 3 disposed on the tongue plate 2.

[0027] Please refer to Figures 1 to 6 As shown, the insulating body 1 has a base portion 11 and a plug plate 12 extending forward from the base portion 11, the plug plate 12 being arranged parallel to the tongue plate 2.

[0028] The insulating body 1 further includes a pair of side baffles 13 arranged opposite each other in the lateral direction, and a first top baffle 14 and a second top baffle 15 spaced apart in the lateral direction. The first top baffle 14 and the second top baffle 15 are both located on the upper side of the plug-in plate 12. Each side baffle 13 extends vertically and upward beyond the upper surface of the plug-in plate 12. The side edges 120 of each side baffle 13 adjacent to the plug-in plate 12 are spaced apart in the lateral direction to form a plug-in space 101.

[0029] Thus, by configuring the side baffles 13 to extend vertically and upward beyond the upper surface of the plug plate 12, each side baffle 13 and the adjacent side edge 120 of the plug plate 12 form a plugging space 101 in the lateral direction. This plugging space 101 can define the plugging path of the mating socket connector (not shown), guide the mating socket connector to plug in the correct lateral orientation, and prevent it from shifting or wobbling in the lateral direction. This allows the conductive terminal 3 to make precise contact with the mating terminal (not shown), reducing problems such as wear, deformation, or poor contact of the mating terminal caused by misalignment. At the same time, by making the side baffles 13 extend upward beyond the upper surface of the plug plate 12, the side baffles 13 can cooperate with the first top baffle 14 and the second top baffle 15 to form a blocking effect above the plug plate 12, effectively preventing oblique insertion and protecting the mating terminal and tongue from damage caused by incorrect operation.

[0030] The plug plate 12 extends forward beyond the front end face of the tongue plate 2, and the side baffle 13 extends forward beyond the front end face of the tongue plate 2. Thus, before the tongue plate 2 and its conductive terminals actually make contact with the terminals of the mating socket connector, the forward-protruding plug plate 12 and side baffle 13 have already begun contacting the mating socket connector. From the start of insertion, this corrects any lateral offset or angular deviation that may occur in the mating socket connector, thereby achieving pre-guidance and initial positioning, enhancing anti-misalignment capabilities, significantly improving insertion smoothness and fault tolerance, and reducing the risk of initial misalignment.

[0031] The tongue plate 2 protrudes from the front side of the base portion 11, and the conductive terminals 3 are arranged on the upper and lower surfaces of the tongue plate 2 to contact the mating terminals. In this embodiment, the tongue plate 2 is a portion of a circuit board protruding from the front side of the base portion 11, and the conductive terminals 3 are gold fingers disposed on the circuit board.

[0032] Please refer to Figure 1 , Figure 6 and Figure 7As shown, the side baffle 13 and the first and second top baffles 14 and 15 all extend forward beyond the front end face of the plug-in plate 12. This forms a forward-protruding, three-sided surrounding three-dimensional guide structure, which more deeply protects the plug-in plate 12 and the tongue plate 3 within this three-dimensional guide structure, thereby achieving a more complete and forward-extending "protective shield" and "guide frame," and more effectively reducing the possibility of successful forced oblique insertion.

[0033] In this embodiment, the first top baffle 14 and the adjacent side baffle 13 are integrally connected in an L-shape, and a slot 102 is formed between the second top baffle 15 and the adjacent side baffle 13, and the slot 102 is open to the front.

[0034] Thus, the main load is borne by the first top baffle 14 connected to the adjacent side baffle 13, and the slots formed between the second top baffle 15 and the adjacent side baffle 13 allow for local flexible deformation, thereby balancing structural strength and fault tolerance, and protecting the main structure of the plug connector in extreme cases.

[0035] Furthermore, in this embodiment, the upper surface of the second top baffle 15 is inclined with the outer side higher than the inner side. This not only improves the bending strength of the second top baffle 15, but also disperses impact loads, strengthens the compressive strength of the top structure, prevents the second top baffle 15 from deforming or breaking due to external pressure, and protects the plug plate 12, tongue plate 2 and conductive terminal 3 located below it.

[0036] In this embodiment, the front ends of the pair of side baffles 13 are flush, and the front end of the first top baffle 14 is flush with the front end of the side baffles 13. The front end of the second top baffle 15 is flush with the front end of the side baffles 13.

[0037] The lower end face of the second top baffle 15 is entirely flat and is arranged parallel to the tongue plate 2. Furthermore, the second top baffle 15 also has a recessed portion 151 formed upwards from its lower end face to adapt to the mating socket connector. The first top baffle 14 also has a recessed portion (not shown) formed upwards from its lower end face to adapt to the mating socket connector.

[0038] In addition, such as Figures 1 to 5 As shown, the plug connector 100 also has a locking member 4, which is made of metal. The locking member 4 has a fixing part 41 fixed to the plug plate 12 and an elastic part 42 formed by bending backward from the front end of the fixing part 41. The elastic part 42 has a locking protrusion 421 for locking with the mating socket connector.

[0039] The locking member 4 also has a connecting part 43 that connects the fixing part 41 and the elastic part 42. The plug plate 12 is provided with a pair of upwardly open limiting grooves 121 and a fixing groove 123 that communicates with the limiting grooves 121. The fixing part 41 is fixed in the fixing groove 123 and the connecting part 43 is received in the limiting groove 121.

[0040] In this embodiment, the connecting part 43 is U-shaped with an opening facing rearward, one end of which is connected to the fixing part 41, and the other end of which is oppositely connected to the elastic part 42.

[0041] Please refer to Figure 8 and Figure 9 As shown, in the second embodiment of the plug connector 100 of this utility model, the basic composition and structure of the plug connector 100 are the same as those in the first embodiment. It also includes an insulating body 1, a tongue plate 2 and a conductive terminal 3. Other identical structures will not be described in detail here. The following only describes the differences.

[0042] In this second embodiment, the insulating body 1 of the plug connector 100 also has a pair of bottom baffles 16 respectively connected to the bottom ends of the pair of side baffles 13. The pair of bottom baffles 16 are located below the tongue plate 2 and are spaced apart from the tongue plate 2 in the height direction. This not only achieves a more complete anti-misalignment capability but also enhances the overall structural rigidity and torsional strength of the front of the insulating body 1, optimizes the guiding function and insertion stability, and ensures that any incorrect angle of insertion is physically and forcefully prevented, achieving anti-misalignment without dead angles. This makes the insertion process smoother and more stable, further improving alignment accuracy.

[0043] Specifically, in one embodiment, the pair of bottom baffles 16 are spaced apart in the lateral direction, each bottom baffle 16 having a free end 160 that approaches the other bottom baffle 16 in the lateral direction, the free end 160 being located within the lateral extension range of the tongue plate 2.

[0044] In this way, not only can precise guidance and anti-slant insertion be achieved below the tongue plate 2, but also the stress at the root position where the bottom baffle 16 and the side baffle 13 are connected can be significantly reduced by shortening the cantilever length of the bottom baffle 16 and designing it at intervals, thereby improving the rigidity and durability of the bottom baffle 16 and avoiding the problem of bottom baffle 16 breaking.

[0045] In this embodiment, in the height direction, the height difference between the bottom baffle 16 and the tongue plate 2 is greater than the height difference between the plug plate 12 and the tongue plate 2.

[0046] In this way, the possibility of stress concentration and fatigue cracking caused by repeated insertion and removal at the connection between the bottom baffle 16 and the side baffle 13 can be significantly reduced, thereby reducing the risk of failure at the root of the bottom baffle 16; at the same time, the insertion and removal force can be optimized, and the more balanced force distribution makes the insertion and removal process feel smoother, thereby improving the overall insertion and removal feel.

[0047] In this embodiment, the plug connector 100 also has a cable 5 that is electrically connected to the tongue plate 2 and extends out of the insulating body 1.

[0048] The plug connector 100 of this utility model features side baffles 13 that extend vertically and upward beyond the upper surface of the plug plate 12. Each side baffle 13 and the adjacent side edge 120 of the plug plate 12 form a plugging space 101 in the lateral direction. This plugging space 101 defines the plugging path of the connector, guiding it to the correct lateral orientation and preventing lateral offset or wobbling. This ensures precise contact between the conductive terminal 3 and the mating terminal, reducing wear, deformation, or poor contact caused by misalignment. Simultaneously, by extending the side baffles 13 upward beyond the upper surface of the plug plate 12, they cooperate with the first top baffle 14 and the second top baffle 15 to form a blocking effect above the plug plate 12, effectively preventing oblique insertion and protecting the mating terminal and tongue from damage caused by incorrect operation.

[0049] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
