[0001] The utility model belongs to the technical field of connectors, and in particular relates to a PCB connector with an inclination angle and a connector component. Background Art

[0002] With the update and iteration of communication technology, the integration level of communication products is getting higher and higher. As a key component of the signal transmission assembly, the connector has also ushered in new challenges. Small size, high reliability and low cost have become the general consensus of connector design. At present, there are two main types of PCB connectors commonly used in communication: straight and curved. The hole position of the curved PCB connector generally corresponds to the conventional 90° transition. At present, the panel connector connected to the chassis is mostly 90° transferred when it is matched with the PCB connector in the chassis. Figure 1 When the panel connector I200 is mated with the PCB connector, it is inconvenient for the operator to directly observe the mating surface of the PCB connector. Moreover, if there is an unconventional 90° transition between the contacts of the curved PCB connector, it is generally necessary to add special parts to ensure the fixity and reliability of the product contacts.

The device is aimed at the conventional 90° transfer mode of the existing panel connector and the PCB connector. When realizing the unconventional 90° transfer, the operator can directly observe the mating surface of the PCB connector and quickly and accurately plug it in.

[0004] One of the purposes of the utility model is to provide a PCB connector with an inclination angle, comprising an insulator and a pin terminal, wherein the pin terminal is fixed in the inner cavity of the insulator, the pin terminal comprises a contact piece and a terminal body connected to the tail end of the contact piece, the contact piece extends into the terminal cavity of the plug-in surface of the insulator, the terminal body comprises a connecting portion connected to the contact piece and a pin portion connected to an adaptable PCB board, and the direction in which the pin portion extends out of the bottom surface of the insulator is not parallel to the plane A where the plug-in surface is located.

[0005] As a preferred embodiment, an intermediate insulating pressure plate and a tail insulating pressure plate are spaced apart in the insulator, a part of the pin terminals are arranged between the intermediate insulating pressure plate and the insulator, and another part of the pin terminals are arranged between the intermediate insulating pressure plate and the tail insulating pressure plate, and the intermediate insulating pressure plate and the tail insulating pressure plate are used to limit the pin terminals.

[0006] As a preferred embodiment, the middle insulating pressure plate and the tail insulating pressure plate both include a pressure plate body and a stop column. The stop column is arranged on one side end face of the pressure plate body and is arranged toward the plug-in surface. The stop column corresponds one-to-one to the tail end of the contact piece. The stop column is used to limit the contact piece from jumping away from the plug-in surface when the connector is plugged in or out.

[0007] As a preferred solution, a limiting platform is provided at one end of the terminal cavity close to the plug-in surface to prevent the contact piece from jumping toward the plug-in surface.

[0008] As a preferred solution, the pin portion is formed by stamping a strip material; the contact member comprises an annular base and a spring extending from one end of the annular base, and the spring is arranged around one end of the annular base to form a socket structure.

[0009] As a preferred embodiment, a stop boss is arranged around the connection between the stop column and the insulating pressure plate. After the insulating pressure plate and the contact piece are assembled, the end of the stop column abuts against one end of the annular base without a spring leaf, and the stop boss abuts against a side plane of the pin portion facing away from the plug-in surface.

[0010] As a preferred solution, the pin terminal further includes a cantilever, a first end of the cantilever is connected to an end of the connecting portion, and a second end of the cantilever is connected to an end of the pin portion.

[0011] As a preferred embodiment, the pressure plate body of the intermediate insulating pressure plate is provided with a supporting positioning portion, and the supporting positioning portion is provided with a supporting surface on the side facing away from the pressure plate body, and the supporting surface is in cantilever support contact with at least one pin terminal arranged between the intermediate insulating pressure plate and the tail insulating pressure plate.

[0012] A second object of the present utility model is to provide a connector assembly, comprising a PCB connector as described in any one of the above items and a panel connector adapted thereto.

[0013] Compared with the prior art, the utility model has at least the following beneficial effects:

[0014] First, this solution, through structural improvement of the PCB connector, changes the previous plug-in method of the panel connector and the PCB connector with a 90° transition. By setting a plug-in structure with an angle on the PCB connector, when the panel connector and the PCB connector are plugged in, the plug-in is achieved in a non-90° transition manner. The purpose of such a design is that the plug-in surface of the PCB connector and the protruding end of the pin terminal and the connecting part of the PCB board are at a certain degree of inclination α. ​​The inclination α can effectively ensure that the operator can clearly see the plug-in surface during the plug-in process, reduce the difficulty of plug-in, protect the plug-in terminal, and achieve fast and accurate plug-in.

[0015] Secondly, this solution takes into account that in practice the cantilever of the second pin terminal at the edge is longer.

DETAILED DESCRIPTION

[0035] The present invention is described in detail below by means of exemplary embodiments. However, it should be understood that, without further description, the elements, structures and features in one embodiment may also be beneficially combined in other embodiments.

[0036] It should be noted that: unless otherwise defined, the technical terms or scientific terms used in this document shall have the usual meanings understood by people with ordinary skills in the field to which the utility model belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of the utility model do not express quantitative limitations, but indicate the existence of at least one. The words "include" or "comprise" and the like indicate that the elements or objects appearing before "include" or "comprises" include the elements or objects listed after "include" or "comprises" and their equivalents, but do not exclude other elements or objects with the same function.

[0037] Based on the fact that in the prior art, when the panel connector and the PCB connector are plugged together, it is inconvenient for the operator to directly observe the plugging surface of the PCB connector, the utility model proposes the following solution.

[0038] In a typical embodiment of the utility model, the PCB connector includes an insulator 1 and a plurality of pin terminals, the pin terminals are fixed in the cavity of the insulator 1 by pressing and fitting through an insulating pressure plate, a plug-in surface 11 and a third side surface 12 are provided on the plug-in side of the insulator 1, a through terminal cavity 18 is formed on the plug-in surface 11, the outer shell surface of the PCB connector 100 is composed of the insulator 1 and the outer wall surface of the insulating pressure plate, and the outer shell of the PCB connector 100 has a plug-in surface 11, a third side surface 12, a top surface 13, a bottom surface 14, a first side surface 15, a second side surface 16 and a back surface 18. The plug-in surface 11 is located on the plug-in side, the plug-in surface 11 and the third side surface 12 are not in the same plane, the back surface 17 is located on the opposite side of the third side surface 12, the top surface 13, the first side surface 15, the second side surface 16, and the bottom surface 14 are four side surfaces adjacent to the back surface 17, and the top surface 13, the third side surface 12, the first side surface 15 and the second side surface 16 are all connected to the edge of the plug-in surface 11; the insulator 1 is provided with an inner cavity on one side of the back surface 17, and the inner cavity is used to install the pin terminal and the insulating pressing plate, and the insulating pressing plate is pressed into the inner cavity on the back side of the insulator 1 to form a complete surface.

[0039] In this solution, the pin terminal includes a contact 21 and a terminal body 22 connected to one end of the contact 21, and the terminal body 22 includes a connecting portion 221 and a pin portion 222, wherein the connecting portion 221 and the pin portion 222 are both flat strip materials with a certain width and thickness, and the connecting portion 221 and the pin portion 222 of the terminal body 22 need to be connected through a cantilever. The connecting portion 221 is arranged along the axial direction of the contact 21, and the pin portion 222 is connected to the adapted PCB board 300, and the connecting portion 221 and the pin portion 222 form an obtuse angle, and the pin portion 222 forms a certain angle with the surface A where the plug-in surface 11 is located, and specifically preferably an acute angle.

[0040] In this solution, the terminal body 22 is stamped from a strip material into a bent structure. Preferably, the connection portion 221, the cantilever, and the pin portion 222 are stamped from a strip material as a whole, wherein the cantilever is also a flat strip material with a certain width and thickness, wherein the cantilever is connected to the connection portion 221 and the pin portion 222 at a substantially vertical angle, respectively. Such a design is mainly to take into account the basic parallelism between the connection portions 221 and the pin portions 222 of each group of pin terminals for easy arrangement. It should be pointed out that the vertical method here does not require a strict 90°. When the pin terminals are arranged in rows, the cantilever length of the pin terminals arranged near the middle position to the edge portions on both sides tends to increase based on design requirements.

[0041] In this embodiment, the inner cavity of the back side 17 of the insulator 1 serves as a accommodating and limiting space for the pin terminals, and the middle insulating platen 3 and the tail insulating platen 5 are both used to limit the pin terminals, wherein the middle insulating platen 3 presses a part of the pin terminals into the inner cavity of the insulator 1, and the part of the pin terminals is located between the middle insulating platen 3 and the insulator 1, and the tail insulating platen 5 presses another part of the pin terminals between the middle insulating platen 3 and the tail insulating platen 5.

[0042] In a typical embodiment of this scheme, Fig.14 As described, in a group of pin terminals indicated in the rectangular box and located on the middle insulating platen 3 and the tail insulating platen 5, the second cantilever 41 of one of the second pin terminals 4 near the edge is longer, and is easily deformed under force when the connector is installed. Therefore, a supporting positioning portion 34 is provided at the upper edge of the middle insulating platen 3. The supporting positioning portion 34 is a flat convex block-shaped structure with a certain thickness formed by the top edge of the middle insulating platen 3 protruding outward, and a supporting surface 341 is formed on the end surface of one side of the flat convex block-shaped structure away from the middle insulating platen 3. Specifically, after the middle insulating platen 3 is assembled into the inner cavity of the insulator 1, the supporting surface 341 faces the top surface 13 side, and is used to contact the end surface of the second cantilever 41 on the side facing the bottom surface 14 of the insulator 1, thereby supporting and positioning the second cantilever 41 at this location to prevent it from being deformed under force.

[0043] In this solution, the contact 21 includes an annular base 211 and a plurality of springs 212. The springs 212 are arranged around one end of the annular base 211 to form a socket structure. When plugged in, the plug pin adapted thereto enters the socket between the springs 212 to achieve plug-in connection. After the springs 212 are deformed and expanded outward by force, they have an elastic contraction force to reset toward the center of the socket. Through the elastic structure of the contact 21, a better plug-in effect of the contact can be achieved. The other end of the annular base 211 is fixedly connected to the connecting portion 221. The end provided with the springs 212 is the head end of the contact 21, and the end without the springs 212 is the tail end of the contact 21. The head end of the contact 21 penetrates into the terminal cavity of the plug-in surface 11 of the insulator 1, and the tail end contacts the stop column.

[0044] In this solution, the third side surface 12 and the plugging surface 11 are not in the same plane, and the plugging surface 11 is adapted to be connected with the panel connector II 201. The plugging surface 11 is adjacent to the top surface 13, the first side surface 15, the second side surface 16, and the third side surface 12, respectively, wherein the plugging surface 11 and the top surface 13 form an obtuse angle, and the plugging surface 11 is perpendicular to the first side surface 15 and the second side surface 16, respectively, and the plane A where the plugging surface 11 is located forms an angle α with the third side surface 12, the third side surface 12 is perpendicular to the bottom surface 14, the first side surface 15, and the second side surface 16, respectively, and the third side surface 12 is arranged parallel to the back surface 17, and a transition connection area is arranged between the third side surface 12 and the plugging surface 11. Specifically, the transition connection area can be set as a raised portion 111 protruding outward as shown in the figure, or it can be set as a flat surface or an inner concave surface as needed.

[0045] In this embodiment, the distance between the side line of the plug-in surface 11 near the bottom surface 14 and the back surface 17 is a first spacing D1, the distance between the side line of the plug-in surface 11 and the top surface 13 and the back surface 17 is a second spacing D2, and the third spacing between the third side surface 12 and the back surface 17 is D3. The first spacing D1 is greater than the second spacing D2, so that the surface A where the side lines of the plug-in surface 11 are located forms an angle α with the back surface 17. Since the pin portion 222 is substantially parallel to the back surface 17, such a setting can make the plug-in surface 11 and the pin portion 222 form a certain angle, so that it is convenient for operators to observe when the plug-in surface 11 is docked with the panel connector II 201, so that the plug-in hole is aligned. Since the observation angle α is formed between the third side surface 12 and the plug-in surface 11, it is ensured that a visual area is formed between the plane C where the plug-in surface of the panel connector II 201 is located and the third side surface 12, which is convenient for operators to observe when plugging. The distance between the third side surface 12 and the back surface 17 is D3, and the first distance D1 is larger than the third distance D3, so that the lower edge line of the plug-in surface 11 is protruding toward the side away from the back surface 17 relative to the third side surface 12. Such a design, on the one hand, ensures that the terminal cavity part has sufficient design space for accommodating length, and on the other hand, ensures that the observation angle α formed between the third side surface 12 and the plug-in surface 11 is large enough and can meet the design requirements, so as to meet the requirement of convenient observation by the operator during plugging.

[0046] In a typical preferred embodiment of the utility model, two groups of pin terminals are provided, including first pin terminals 2 constituting the first group of pin terminals and second pin terminals 4 constituting the second group of pin terminals, the first pin terminals 2 and the second pin terminals 4 are installed on the end surfaces of the middle insulating plate 3 on both sides, wherein the first pin terminal 2 is located between the insulator 1 and the middle insulating plate 3, and the second pin terminal 4 is located between the middle insulating plate 3 and the tail insulating plate 5. The plug-in surface 11 of the insulator 1 is provided with upper and lower groups of terminal cavities 18, and the length of the second pin terminal 4 is greater than the length of the first pin terminal 2. In this embodiment, the terminal cavity 18 includes an upper terminal cavity 181 set as an upper group and a lower terminal cavity 182 set as a lower group, the contact piece 21 of the first pin terminal 2 is installed in the lower terminal cavity 181, the pin portion 222 of the first pin terminal 2 is placed in the spacing groove of the middle insulating plate 3, and extends outward from the bottom surface 14 of the insulator 1, and the contact piece of the second pin terminal 4 is installed in the upper terminal cavity 182, and extends outward from the inside of the insulator 1. The second pin terminal 4 has a similar structure to the first pin terminal 2 , except that the second pin terminal 4 has a larger pin length than the first pin terminal 2 .

[0047] In this embodiment, the plug-in interface of the terminal cavity 18 forms a limit platform 19, the inner diameter of the limit platform 19 is smaller than the outer diameter of the end of the spring leaf 212 of the elastic contact piece 21, and the limit platform 19 can abut against the end of the spring leaf 212. Therefore, the limit platform 19 can limit the movement of the contact piece 21 toward the plug-in surface 11 through a stopping effect.

[0048] In this solution, a fixing plate 101 for fixing and placing the pin terminal is provided in the inner cavity of the insulator 1, and a first spacing groove 102 for placing the pin portion 222 of the first pin terminal 2 is formed on the bottom surface of the fixing plate 101. Positioning platforms 103 are provided on both sides of the first spacing groove 102 in the inner cavity. The positioning platforms 103 are used to limit the installation position of the intermediate insulating pressure plate 3. The positioning platforms 103 can be set as follows Figure 5 The concave arc structure shown.

[0049] Specifically, the insulating platen includes an intermediate insulating platen 3 and a tail insulating platen 5, wherein the intermediate insulating platen 3 is used to press and fix the first pin terminal 2 in the inner cavity of the insulator 1, the first end surface of the intermediate insulating platen 3 presses the first pin terminal 2, and presses and fixes the first pin terminal 2 in the cavity of the insulator 1, and the pin portion 222 of the first pin terminal 2 is separated by the first spacing groove 102. The intermediate insulating platen 3 includes a platen body 32, and a first stopper column 31 corresponding to the terminal contact piece 21 is arranged on the end surface of the platen body 32 pressed with the first pin terminal 2, and the end of the first stopper column 31 abuts against the tail of the terminal contact piece 21 of the first pin terminal 2, and is used to limit the terminal contact piece 21 from escaping from the lower terminal cavity 182 in the direction away from the plug-in surface 11, and the stopper structure on the intermediate insulating platen 3 is composed of a first stopper column 31 and a first stopper boss 32, and the first stopper boss 32 is arranged at the periphery of the root connection of the first stopper column 31. To ensure effective abutment against the tail of the contact piece 21, the first stop column 31 is designed to be a columnar structure, and the columnar structure forms at least one cutting plane 311 along the axial direction of the first stop column 31. Preferably, the cross section of the first stop column 31 is surrounded by an arc and a straight line, and the arc is a minor arc or a major arc. The cross section of the first stop column 31 is basically an approximately semicircular structure or a fan-shaped structure, so as to avoid interference between the insulating pressure plate and the contact piece in space, wherein the end of the first stop column 31 abuts against the end of the annular base 211 to prevent the contact piece 21 from moving away from the plug-in surface 11 when plugged in, and the cutting plane 311 fits with the upper end surface of the connecting portion 221 of the terminal body 22, which can adapt to the design shape of the connecting portion 221 on the one hand, and can also improve the bending strength of the connecting portion 221 at the same time.

[0050] In this embodiment, a first stop boss 32 is also provided at the bottom of the first stop column 31. When the panel connector 200 is plugged into the PCB connector 100, the panel connector 200 will apply a certain assembly force to the PCB connector 100. At this time, the first stop column 31 abuts against the end ring of the annular base 211 of the first pin terminal 2, and the first stop boss 32 abuts against the main plane of the terminal body 22. Specifically, the first stop boss 32 contacts the end face of the pin portion 222 away from the plug-in face 11, thereby preventing the contact member from jumping in the product due to the plugging and unplugging of the panel connector 200, and ensuring the fixity and reliability of the contact member 21 in the product. At the same time, the provision of the first stop boss 32 also effectively ensures the strength of the first stop column 31 itself. A row of second spacing grooves 35 are provided on the end face of the middle insulating plate 3 facing the side of the tail insulating plate 5. The function of the second spacing grooves 35 is to place the pin portion 222 of the second pin terminal 4 and isolate the first pin terminal 2. Positioning plates 36 are provided on both sides of the middle insulating platen 3, and the outer edges of the positioning plates 36 are arc-shaped and protrude outward. The positioning plates 36 match the shapes of the stoppers 103 on both sides of the inner cavity of the insulator 1. After the inner cavity of the middle insulating platen 3 is installed in place, the positioning plates 36 abut against the positioning plates 103. After the positioning plates 36 abut against the positioning plates 103, the installation position of the middle insulating platen 3 can be limited.

[0051] In this solution, the tail insulating plate 5 is used to press and fix the second pin terminal 4 on the middle insulating plate 3 and the insulator 1. A second stop column 51 is provided on the pressing surface of the tail insulating plate 5. The end of the second stop column 51 abuts against the end ring of the annular base 211 of the second pin terminal 4 to limit the contact 21 from escaping from the upper terminal cavity 181 in the direction away from the plug-in surface 11. A second stop boss 53 is provided at the connection between the second stop column 51 and the tail plate body 52. ​​The function of the second stop boss 53 is to contact the end face of the pin portion 222 away from the plug-in surface 11, thereby providing support for the assembly force of the pin portion 222, and ensuring the fixity and reliability of the contact 21 in the product. At the same time, the provision of the first stop boss 32 also effectively ensures the strength of the first stop column 31 itself. A buckle 54 is provided at the outer edge of the tail insulating pressure plate 5, and a slot 104 is provided on the top surface 13 of the cavity side wall, the first side surface 15, and the second side surface 16 of the insulator 1. A mounting bevel is provided on one side of the mounting direction of the buckle 54, and an anti-slip surface is provided on one side of the disassembly direction of the buckle 54. By providing the mounting bevel, the buckle 54 is easier to install into the slot 104. By providing the stopping effect of the anti-slip surface, the buckle 54 will not easily detach from the slot 104, and the tail insulating pressure plate 5 is firmly fixed in the cavity of the insulator 1.

[0052] Similarly, the structure and function of the second stop column 51 of the tail insulating pressure plate 5 are similar to those of the first stop column 31. In order to ensure effective abutment against the tail of the contact piece 21 of the second pin terminal 4, the second stop column 51 is designed to be a columnar structure, and the columnar structure forms at least one cutting plane along the axial direction of the second stop column 51. Preferably, the cross-section of the second stop column 51 is surrounded by an arc and a straight line, and the arc is a minor arc or a major arc. The cross-section of the second stop column 51 is basically an approximately semicircular structure or a fan-shaped structure, so as to avoid interference between the insulating pressure plate and the contact piece in space, wherein the end of the second stop column 51 abuts against the tail of the annular base of the contact piece of the second pin terminal 4, so as to prevent the second pin terminal 4 from jumping away from the plug-in surface 11 when plugged in, and the cutting plane fits with the upper end surface of the connecting part of the terminal body of the second pin terminal 4, which can adapt to the design shape of the connecting part on the one hand, and at the same time improve the bending strength of the connecting part.

[0053] In one embodiment of the present invention, the bottom of the insulator 1 is welded and fixed to the PCB board 300 through a welding piece 6. Specifically, a mounting groove for mounting the welding piece 6 is provided on one side end face of the insulator 1, and the welding piece 6 is fixed in the mounting groove and the bottom thereof is exposed to achieve connection with the PCB board 300.

[0054] The present solution also provides a connector assembly, including a PCB connector 100 and a panel connector II 201. A mounting hole for mounting the panel connector II 201 is provided at a corresponding position on the chassis 400. After the panel connector II 201 is fixed in the mounting hole, it can be plugged into the PCB connector 100. Since the plugging surface of the PCB connector 100 has a corresponding tilt structure, when the plugging surface 11 of the PCB connector 100 is plugged into the panel connector II 201, since the plugging surface 11 of the PCB connector 100 and the protruding end of the terminal body 22 are at a certain tilt angle α, the tilt angle α can effectively ensure that the operator can clearly see the plugging surface during the plugging process, reduce the difficulty of plugging, protect the plugging terminals, and achieve fast and accurate plugging.

[0055] The present scheme further takes into account that, in order to achieve more convenient plugging, a tilted structure may be provided on the chassis fixing plate on which the panel connector Ⅱ 201 is installed. The purpose of providing the tilted structure is to make it easier for operators to perform plugging operations, provide more humanized operations, and facilitate observation of the plugging terminals of the panel connector Ⅱ 201, so as to achieve one-to-one alignment of the plugging terminals with the contacts in the plugging holes for plugging.
