Description

Technical Field

[0001] The present invention belongs to the technical field of micro-rectangular connectors, and particularly relates to a 37-pin three-row anti-misinsertion micro-rectangular connector. Background Art

[0002] Micro-rectangular electrical connectors are a type of electrical connectors that have developed rapidly in China in recent years. Previously, they mainly relied on imports. They are small in size, light in weight, and high in reliability, and have extremely high application value and development potential in military fields such as aerospace. Along with the development of miniaturization and diversification of the whole machine, board-to-board connectors are increasingly widely used in the aerospace field.

[0003] Currently, the product spectrum of 1mm pitch 37-pin MDM1 micro-rectangular connectors in the market is as Figure 1 shown, and the product spectrum of 39-pin MDM1 micro-rectangular connectors is as Figure 2 shown. The new technical requirements require that the user installation opening size of the 37-pin MDM1 connector be the same as that of the 39-pin MDM1 connector. Since the conventional 37-pin connector in a row is a two-row design (19 pins + 18 pins), the user installation opening size is inconsistent with that of the 39-pin connector and cannot meet the user's requirements. In addition, for traditional connectors to separate the connector plug and socket, the locking screw is first loosened and then forcibly separated by an external force, which not only does not facilitate the user's use but also may cause damage to the connector when the applied force is inappropriate. Therefore, it is necessary to redesign the product spectrum of the 37-pin micro-rectangular connector to solve the above technical problems. Summary of the Invention

[0004] In view of the above technical problems, the present invention provides a 37-pin three-row anti-misinsertion micro-rectangular connector. This structure adopts a three-row 37-pin design of "12 + 13 + 12", realizing reliable replacement of 37-pin and 39-pin connectors.

[0005] The present invention solves the above problems through the following technical means:

[0006] A 37-pin three-row anti-misinsertion micro-rectangular connector, characterized in that it includes a plug, wherein: a plug cavity is formed by hollowing out the middle of the plug housing of the plug, a plug base is installed inside the plug cavity, a plug dust cover is sleeved outside the plug base, wire-carrying pins are arranged equidistantly on the plug base, connection holes are symmetrically opened around the plug housing, plug screws for connecting a circuit board are installed in the connection holes, a plug positioning boss is provided at the bottom end of the plug dust cover, and the bottom ends of both sides of the plug dust cover extend outward and butt top holes are opened at their ends; the number of the wire-carrying pins is 37, and the 37 wire-carrying pins are symmetrically arranged in three rows, with 12 in the first row, 13 in the second row, and 12 in the third row.

[0007] Preferably, it further includes a socket that can be plugged into the plug, where: a middle part of the socket housing of the socket is hollowed out to form a socket cavity, a socket base is installed inside the socket cavity, a socket dust cover is sleeved outside the socket base, a wiring groove is formed on one side of the bottom of the socket dust cover, a docking ear extends outward from the bottom of the socket dust cover, docking bottom holes are symmetrically formed on the docking ear, sleeve pins are arranged at equal intervals in the vertical direction on the socket base, terminal posts are arranged at equal intervals in the horizontal direction on the socket base, the inside of the terminal posts is connected to the sleeve pins through bent parts, and the sleeve pins are used to plug into the wire pins.

[0008] Preferably, a fixing sleeve is installed in the docking bottom hole, and a docking screw is rotatably installed inside the fixing sleeve, where: a round hole for screwing the docking screw is formed at the outer end of the fixing sleeve, a positioning ring groove for connecting the docking bottom hole is arranged in the middle of the fixing sleeve, and a positioning flange for limiting is arranged at the end of the fixing sleeve; the docking screw is used to connect the docking top hole.

[0009] Preferably, the column pitch range of the wire pins is 1.0 mm to 1.2 mm, and the row pitch range of the straight pins is 0.8 mm to 1.0 mm.

[0010] The present invention has the following beneficial effects:

[0011] 1) This structure designs the type spectrum of the 37-core product into three rows (12 + 13 + 12), so as to meet the requirement that the user's installation opening size is consistent with that of the 39-core connector. Among them, the column pitch range of the wire pins is 1.0 mm to 1.2 mm, and the row pitch range of the straight pins is 0.8 mm to 1.0 mm.

[0012] 2) This structure designs a boss structure on the housing, which can effectively prevent misplugging with the 37-core product and avoid burning out the circuit. The number and position of the bosses can be flexibly adjusted, which can effectively prevent the situation of misplugging multiple connectors with the same core number on the same mounting plate.

[0013] 3) The screw of this mechanism is a non-detachable screw, and the function of separating the connector is realized by rotating the screw, which facilitates the use of the user and reduces the damage caused by improper use of the connector. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0025] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is 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 orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0026] The present invention will be described in detail below with reference to the accompanying drawings.

[0027] As Figures 3 to 8 shown, the 37-core three-row anti-misinsertion micro-rectangular connector includes a plug. In the figure, the middle of the plug housing 101 of the plug 1 is hollowed out to form a plug cavity 102. A plug base 103 is installed inside the plug cavity 102. A plug dust cover 104 is sleeved outside the plug base 103. Wire-carrying pins 105 are arranged equidistantly on the plug base 103. Connecting holes 106 are symmetrically opened around the plug housing 101. Plug screws 107 for connecting the circuit board are installed in the connecting holes 106. A plug positioning boss 108 is provided at the bottom end of the plug dust cover 104. The bottom ends of both sides of the plug dust cover 104 extend outwards and butt top holes 109 are opened at their ends.

[0028] It should be noted that a boss structure is designed on the dust cover of this structure, which can effectively prevent misinsertion with 37-core products and avoid burning out the circuit. The number and position of the bosses can be flexibly adjusted, which can effectively prevent misinsertion of multiple connectors with the same core number on the same mounting plate.

[0029] In the figure, the number of wire-carrying pins 105 is 37. The 37 wire-carrying pins 105 are arranged symmetrically in three rows. The number of the first row is 12, the number of the second row is 13, and the number of the third row is 12. Specifically, the type spectrum of the 37-core product is designed as 12 + 13 + 12 in three rows, so as to meet the requirement that the installation opening size of the user is the same as that of the 39-core connector. Among them, the range of the column pitch of the wire-carrying pins is 1.0 mm to 1.2 mm, and the range of the row pitch of the straight pins is 0.8 mm to 1.0 mm.

[0030] Specifically, the installation opening size of the 37-pin MDM1 connector should be the same as that of the 39-pin MDM1 connector. Since the conventional 37-pin connector in a regular row is a double-row design of 19 pins + 18 pins, the installation opening size of the user does not match that of the 39-pin connector and cannot meet the user's requirements. The installation opening size of the newly designed three-row 37-pin MDM1 connector is the same as that of the 39-pin connector, as Figure 9 shown.

[0031] In the figure, it also includes a socket 2 that can be inserted into the plug 1, where: a socket cavity 202 is formed by hollowing out the middle of the socket housing 201 of the socket 2. A socket base 203 is installed inside the socket cavity 202. A socket dust cover 204 is sleeved outside the socket base 203. A wiring groove 205 is opened on one side of the bottom of the socket dust cover 204. The bottom of the socket dust cover 204 extends outward to form a docking ear 206. Docking bottom holes 207 are symmetrically opened on the docking ear 206. Sleeve pins 210 with sleeves are arranged at equal intervals in the vertical direction on the socket base 203. Terminal posts 211 are arranged at equal intervals in the horizontal direction on the socket base 203. The inside of the terminal posts 211 is connected to the sleeve pins 210 with sleeves through bent parts. The sleeve pins 210 with sleeves are used to insert into the wire pins 105 with wires.

[0032] In the figure, a fixing sleeve 208 is installed in the docking bottom hole 207. A docking screw 209 is rotatably installed inside the fixing sleeve 208, where: a round hole 212 for screwing the docking screw 209 is opened at the outer end of the fixing sleeve 208. A positioning ring groove 213 for connecting the docking bottom hole 207 is arranged in the middle of the fixing sleeve 208. A positioning flange 214 for limiting is arranged at the end of the fixing sleeve 208; the docking screw 209 is used to connect the docking top hole 109. It should be noted that a long groove for deformation is opened on the fixing sleeve 208. Through the long groove, the fixing sleeve 208 can have a certain deformation ability to facilitate the installation of the docking screw 209.

[0033] During actual operation, the screw of this mechanism is a non-detachable screw. The function of separating the connector is achieved by rotating the screw, which facilitates the user's use and reduces the damage caused by improper use of the connector.

[0034] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
