Description

  The present invention relates to an electric connector and a double-sided male connector having a shell.

  Currently, the most popular data transmission standard for personal computer equipment is the Universal Serial Bus (USB). By using the female connector and transmission line manufactured in this standard, Peripheral devices such as a mouse and keyboard attached to the computer are immediately detected by the PC so that they can be used immediately.

  Currently, USB has two types of standards, 2.0 and 3.0. As shown in FIG. 1, the existing USB 2.0 male connector 90 is provided with a plastic seat 91 and a metal outer shell 92. The metal outer shell 92 covers the plastic seat 91, a fitting space 93 is formed between the metal outer shell 92 and the plastic seat 91, and only one surface of the plastic seat 91 is exposed to the fitting space 93. A row of contacts 94 is provided. Currently, the official standard of the USB Association is that the overall height i is 4.5 mm, the half height j corresponding to the fitting space 93 is 2.25 mm, and the height k of the fitting space 93 is 1.95 mm.

  Currently, a USB 2.0 female connector is provided with a single row of contacts on one side of the tongue, and when used, the USB 2.0 male connector is inserted correctly in the insertion direction. Can be connected. In addition, a foolproof design is applied to the contact points of the two so that a reliable electrical connection can be made when the USB male connector is inserted. As shown in FIG. 1A, when the marking 97 on one surface of the grip portion 96 of the USB 2.0 male connector 90 faces upward, that is, the forward direction. At this time, the contact 94 is facing upward, and when inserted in the forward direction, it can be inserted to make an electrical connection. As shown in FIG. 1B, when inserting the USB male connector in the opposite direction, Since the insertion is impossible, the electrical connection after the insertion can be ensured in this way. The user usually inserts from time to time, but the probability of not being able to insert is 1/2, and it is often necessary to insert twice, which is inconvenient in use.

  The existing USB 2.0 female connector 80 shown in FIG. 2 includes a plastic seat 81, a metal outer shell 83, and terminals 87. A tongue-shaped piece 82 that extends horizontally is integrally formed at the tip of the plastic seat 81, the metal outer shell 83 is positioned at the tip of the plastic seat 81 to form a connecting groove 84, and the tongue-shaped piece 82 is positioned below the connecting groove 84. The four terminals 87 are fixed to the plastic seat 81, extended in the forward direction and arranged on the tongue-shaped piece 82, and a contact 88 is provided near the end. To do.

  The USB 2.0 female connector 80 has a foolproof design that matches the male connector. The official standards of the USB Association are as follows. That is, the height o of the connecting groove is 5.12, the tongue piece thickness p is 1.84 mm, the tongue piece upper height s is 0.72 mm, and the tongue piece lower height q is 2.56 mm. Thus, when the insertion space 93 of the USB 2.0 male connector 90 is inserted downward, the insertion space 93 and the tongue-like piece 82 are fitted and positioned, and the half-body height j (2.25 mm) is set in a tongue shape. It fits into the lower height q (2.56mm) of the piece. When the direction of the USB 2.0 male connector 90 is reversed, it cannot be inserted. Further, the horizontal distance t from the insertion end 86 of the localization plane of the connecting groove 84 to the first contact 88 of the first terminal is 3.5 mm.

  FIG. 2AA shows the existing USB 3.0 female connector 85. Its structure and related size are almost the same as the USB 2.0 female connector 80. The two kinds of differences are that the tongue-shaped piece 82 of the USB 3.0 female connector 85 is relatively long, and five elastic lines in the front stage. There is no second contact 89 to install. Further, the horizontal distance t from the insertion end 86 of the localization plane of the connecting groove 84 to the first contact 88 of the first terminal is 4.07 mm.

  The structure and related size of the USB3.0 male connector is almost the same as that of the USB2.0 male connector 90. The two types of differences are that the USB3.0 protrudes into the fitting space and is elastic. There are many points of contact.

  Regardless of whether the known USB female connector is 2.0 or 3.0, it is not possible to insert the male connector in two directions at the time of use because of the contact form on a single surface. Therefore, in order to increase the convenience in use and to enable electrical connection in both the forward and reverse directions and meet the user's request, the applicant has a male with a shell having an electrical connection function on both sides. Researched and developed the connector.

  The main object of the present invention is to provide a double-sided male connector having a shell that floats the connecting plate up and down in the connecting groove to realize the double-sided connection effect of the female connector.

  To achieve the above object, a double-sided male connector with a shell provided by the present invention includes an insulating base, two rows of first contacts, and a shell. The insulating base is provided with a connecting plate at the tip thereof, the connecting plate is provided with a relatively large area of upper and lower surfaces facing each other, the first contact is exposed to the upper and lower surfaces of the connecting plate, and the shell is connected to the insulating base. A groove is provided, an insertion port is formed at the tip, and the connecting plate is positioned in the connecting groove. Also, the present invention is characterized in that the shell and the connecting plate float and move relative to each other. The connecting plate floats and moves up and down with respect to the shell, or the shell moves up and down with respect to the connecting plate. Float to move.

  Further, the connecting plate floats up and down in the connecting groove and moves to achieve a double-sided connection effect with the female connector.

  The double-sided male connector provided with the shell of the present invention achieves the double-sided connection effect with the female connector by moving the shell and the connecting plate up and down relative to each other.

  The foregoing and other objects, advantages and features of the present invention will be further understood by a detailed description of a preferred embodiment disclosed below with reference to the drawings.

  As shown in FIGS. 3 to 9, the first embodiment of the present invention is a flash memory that can be electrically connected on both sides corresponding to the USB3.0 standard, and is a female connector that can be electrically connected on both sides in the forward and reverse directions. Insulating base 30, two rows of second terminals 50, shell 60, position limiting structure 65, position adjusting structure 70, electronic unit 78, and case 75.

  The insulating base 30 is made of a hard material and includes a plastic seat 31 and a printed circuit board 32 that are not elastic and does not twist. The plastic seat 31 includes an upper seat coupled to the upper surface and the lower surface of the rear portion of the printed circuit board 32. A lower seat is provided, and between the rear portion of the printed circuit board 32 and the plastic seat 31, a storage space for installing electronic components is formed on the upper and lower surfaces of the printed circuit board 32. A plastic seat 31 is projected from the front portion of the printed circuit board 32 to form a connecting plate 33. Four first contacts 34 are arranged on the upper and lower surfaces of the connecting plate 33, and the two rows of first contacts 34 are printed. It may be a contact point of the circuit of the substrate 32 and may be a metal terminal. A top and bottom inclined surface 39 is provided at the tip of the connecting plate 33 to form a pointed cone. As shown in FIGS. 8 and 9, the connecting plate 33 is provided with five hollow grooves 36 arranged in a line behind the first contact 34, and the upper and lower surfaces of the rear portion of the connecting plate 33 correspond to the five hollow grooves 36, respectively. Five solder portions 35 are provided. The solder part 35 is a row of conductive parts, and both the first contact 34 and the solder part 35 are connected to the circuit 37, respectively.

  There are five second terminals 50 in two rows, and an extending portion 51, a fixing portion 54, and a pin 52 are provided from one end of the second terminal 50 to the other end. The extending part 51 moves up and down with elasticity, and projects a second contact 53. First, the two rows of second terminals 50 are attached to the upper and lower seats of the plastic seat 31 by the fixing portion 54, and the upper and lower seats of the plastic seat 31 are coupled to the rear portion of the printed circuit board 32. The pin 52 of the second terminal 50 is soldered to the solder part 35. The two rows of second contacts 53 protrude from the upper and lower surfaces of the connecting plate 33 and can move up and down with elasticity in the hollow groove 36. After the second contact 53 is positioned at the first contact 34, as shown in FIG. 6A, a relatively narrow inclined surface 55 of the plate surface is provided in front of the second contact 53 of the second terminal 50. The second contacts 53 of the second terminals 50 in the row are made to correspond to each other vertically, and the inclined surfaces 55 of the second terminals 50 in the two rows are separated from each other left and right. A USB 3.0 contact interface is formed between the first contact 34 in a row and the second contact 53 in a row without matching. As shown in FIGS. 7, 8, and 9, the circuit sequences of the two rows of first contacts 34 are arranged so as to be opposite to each other, and the circuit sequences of the two rows of second contacts 53 are arranged so as to be opposite to each other. The two rows of the first contacts 34 having the same circuit sequence are electrically connected to form a pair of conductive through holes 38, and the two rows of the second contacts 53 having the same circuit sequence are also electrically connected. The holes 38 are electrically connected to form a set. The circuit sequence of the first contacts 34 in the two rows is 1 that is a power supply circuit (VBUS), and the circuit sequence 2 (D−) and the circuit sequence 3 (D +) are a pair of signal circuits and a circuit sequence 4 ( GND) is a ground circuit. Circuit sequence 5 (RX−) and circuit sequence 6 (RX +) of two rows of second contacts 53 are a pair of signal circuits, circuit sequence 8 (TX−) and circuit sequence 9 (TX +) are another pair of signal circuits, Circuit order 7 (GND) is a ground circuit. Among them, the circuit sequence 1 of the first contacts 34 in the two rows must be electrically connected through the Schottky diode 313 first, since a short circuit of the power supply circuit must never occur. Since the Schottky diode 313 mainly has a function of preventing a reverse current flow, it achieves a short-circuit protection effect.

  The above-described method for protecting a short circuit using a Schottky diode is a kind of technique for safely protecting a circuit for preventing electronic backflow prevention or short circuiting. The effect of safely protecting the circuit can also be achieved by a number of methods such as short-circuit prevention electronic components, circuit safety protection components, safety circuit installation means, and the like.

  The shell 60 is made of a metal material, and it covers the insulating substrate 30. A connecting groove 61 is formed in the shell 60, the tip is used as an insertion port, and the connecting plate 33 is located in the connecting groove 61. A vertical floating interval is provided between the insulating base 30 and the shell 60, and the shell 60 and the connecting plate 33 can be relatively floated and moved up and down.

In the retreat prevention structure, elastic reverse claw portions 62 are provided on both sides of the rear portion of the shell 60 (see FIG. 7A), fitting holes 311 are provided on both sides of the rear portion of the plastic seat 31 of the insulating base 30, and the elastic reverse claw portions 62 are used. Thus, the fitting hole 311 is hooked to prevent retreat. Further, projecting edges 310 are provided on both sides of the end of the plastic seat 31 of the insulating base 30, and the shell 60 is pressed by the projecting edges 310 to be localized.

  The position limiting structure 65 limits the vertical movement position of the connecting plate 33 with respect to the shell 60. The position limiting structure 65 is integrally connected to the two side surfaces of the shell 60 and protrudes toward the connecting groove 61. Two pairs of upper position limiting pieces 651 and lower position limiting pieces 652 are provided, and there is an altitude difference between each upper position limiting piece 651 and lower position limiting piece 652, and the connecting plate 33 is limited to each upper position limiting piece 651 and lower position. Located between the pieces 652. The difference in height is the operating area of the connecting plate 33. The upper position limiting piece 651 and the lower position limiting piece 652 protrude inward from the two side surfaces of the shell 60 and forward from the insertion opening of the connecting groove 61 in the forward direction. The two ends of the shell 60 are open, and the upper position limiting piece 651 and the lower position limiting piece 652 operate with elasticity in the side direction. When the upper position limiting piece 651 and the lower position limiting piece 652 are flipped up and down, the upper surface of the shell 60 is immediately cut off. And press the bottom. The clearance is the tolerance that the connecting plate floats up and down with respect to the shell.

Among them, the position adjusting bullet 71 symmetrically presses the upper surface and the lower surface of the plastic seat 31 at the rear of the insulating base 30, and the position adjusting bullet 72 symmetrically presses the upper surface and the lower surface of the connecting plate 33. The adjusting bullet 72 presses between the two first contacts 34 and does not contact the first contacts 34. The position adjustment bullet 71 and the position adjustment bullet 72 protrude inward from the top and bottom surfaces of the shell 60, and the position adjustment bullet 72 ends in the forward direction from the insertion opening of the connecting groove 61 inward. The end of the shell 60 is in an open state, and an opening is formed on the two side surfaces of the upper surface and the bottom surface of the shell 60. The position adjusting structure 70 has the connection plate 33 at the height of the connection groove 61. Position it at an intermediate position.

  The electronic unit 78 is a storage unit, which is electrically connected on the printed circuit board 32, includes a memory and a control circuit, and does not limit the size of the memory. The control circuit controls the memory operation of the electronic unit 78. The two rows of first contacts 34 and the two rows of second contacts 53 are electrically connected to the electronic unit 78.

  The case 75 is made of a plastic material and covers the rear part of the shell 60 and the rear part of the insulating base 30. Among them, the case 75 and the shell 60 are fixedly fitted, a fitting hole 622 is provided in the shell 60, and a fitting hooking portion 76 provided at the tip of the case 75 is fitted into the fitting hole 622 so that the case 75 and the shell are fitted. In order to fix 60, the connecting plate 33 can move up and down with respect to the shell 60.

  As shown in FIG. 7, the height of the shell 60 of the present invention is 4.5 mm to 5.0 mm, and the thickness of the connecting plate 33 is 0.5 mm to 1.6 mm. In this embodiment, when the height of the shell 60 is 4.5 mm, the thickness of the connecting plate 33 is 1 mm, and the material thickness of the shell 60 is 0.3 mm, the height h1 of the space above the connecting plate 33 is The total height h2 of 1.45mm, the connecting plate and the height of the lower space plus the thickness of the material is 2.75mm. In addition, when inserted into the USB 3.0 female connector 85 shown in FIG. 2A, h1 is 1.45 mm which is less than 1.84 mm of the thickness p of the tongue piece 82, and h2 is a height q below the tongue piece 82. Therefore, when the connecting plate 33 cannot move up and down in the connecting groove 61, it cannot be inserted into the USB 3.0 female connector 85.

  FIG. 10 shows a state when the flash memory of this embodiment based on the above-described structure is inserted into the USB 3.0 female connector 85. The space height h1 above the connecting plate 33 is 1.45 mm, and the thickness of the tongue-shaped piece 82 is 1.84 mm larger, so the tip of the connecting plate 33 presses the tongue-shaped piece 82. As shown in FIG. 11, at this time, it is guided to the connecting groove 84 by the top and bottom inclined surface 39, and the connecting plate 33 in the connecting groove 61 moves downward, so that h1 gradually increases and h2 gradually decreases. Become. As shown in FIG. 12, when the connecting plate 33 is inserted until it is positioned, the tongue-like piece 82 is pressed to one side by the upper position limiting piece 651, so that the space above the connecting plate 33 is completely eliminated, and the tongue-like piece 82 is Inserted. The connecting plate 33 in the connecting groove 61 moves downward by about 0.5 mm and is positioned and pressed by the lower position limiting piece 652. At this time, h1 is 1.95 mm and h2 is 2.25 mm, which are completely determined by the USB Association. The connecting plate 33 conforms to the standard, and the connecting plate 33 is positioned and pressed by the lower position limiting piece 652, so that reliable electrical connection can be made.

  The structural feature of this embodiment is that when inserted into the female connector, the upper position limiting piece 651 pushes the tongue-shaped piece 82 to one side, and the lower position limiting piece 652 limits the position of the connecting plate 33 and presses it. The connecting plate 33 can reliably make a reliable electrical connection. In the reverse direction, the lower position limiting piece 652 pushes the tongue-shaped piece 82 to one side, and the upper position limiting piece 651 is connected to the connecting plate 33. Since the position is limited and pressed, the connecting plate 33 can reliably make a reliable electrical connection.

  Further, since the shell from the front end to the end of the insulating base 30 of this embodiment and the shell face each other and can float and move up and down, the connecting body 33 floats and moves up and down with respect to the shell.

The present embodiment based on the above structure has the following effects.
(1) Since the connecting plate 33 floats and moves up and down in the connecting groove 61, double-sided connection to the USB3.0 female connector 85 is possible.
(2) The position adjustment structure 70 positions the connecting plate 33 at an intermediate position in the height of the connecting groove 61.
(3) The position of the connecting plate 33 is limited by the position limiting structure 65 and is pressed to ensure reliable electrical connection.
