The present invention mainly relates to a combination of electronic connectors for transmitting high frequency differential signals, in particular, a whole having a low profile and a small pitch of each signal terminal ( Fine pitch).

Under the trend of active miniaturization of electronic devices, the volume of high-frequency electronic connectors is also constantly required to be reduced, which results in high-frequency electronic connectors having extremely low height and extremely small pitch characteristics. In the present specification, a low-height or very low-height connector refers to a connector that is mounted to a height of a circuit board of not more than five mm (5 mm) in an electronic device or a connector that mates with the connector. . The signal terminals of the small pitch or the very small pitch refer to connectors in which adjacent signal terminals are apart from each other by one centimeter (1 mm) or less. In order to reduce the noise generated by the high-frequency electronic connector in transmitting high-frequency electronic signals, the high-frequency electronic connector is mainly used to transmit differential mode electrical signals or differential electronic signals. Signal. Such high frequency differential signals often form an electronic signal channel through a pair of adjacent signal terminals to transmit high frequency electronic signals. Sometimes, the high-frequency differential signal transmission channel not only has a pair of adjacent signal terminals, but also an adjacent ground terminal, and the combination of the one ground terminal and the pair of signal terminals forms an electronic signal channel. The grounding terminal is used to reduce high frequency electromagnetic interference between the two signal terminals or between the electronic signal channel and the adjacent electronic signal channel. As a matter of course, the electronic signal transmitted by the high-frequency electronic connector does not stop at the high-frequency differential electronic signal. According to actual needs, the high-frequency electronic connector can also be appropriately configured through the position between the terminals. The frequency electronic connector can also transmit power signals, low frequency electronic signals or signal grounds transmitted with specific terminals.

Each of the signal terminals B has a connecting portion B1 and a contact portion B2, and each of the signal terminals B has an interference relationship with the main body portion A2 of the insulating case A. By the interference relationship, each of the signal terminals B and A frictional force is generated between the insulating housings A to fix the signal terminals B in the insulating housing A. Each of the signal terminal B connecting portions B1 is solderable to a circuit board (not shown) in an electronic device, thereby electrically connecting each of the signal terminals B to an electronic circuit on the circuit board. Each of the signal terminal B contact portions B1 extends into the insulating case A receiving chamber A1, and the shielding case C is at least around the periphery of the insulating case A.

In the Kamata I patent, the shield case C has a plurality of elastic portions C1 extending from the outside of the insulating case A toward the insulating case A receiving chamber A1, and the elastic portions C1 of each of the shielding cases C can be regarded as respectively Is a terminal electrically connected to the grounding circuit on the circuit board, so when the connector and the pair of connectors (refer to Figure 14, Kamata II patent) mating, the elastic portion C1 of the shielding case C The shield case C or the ground terminal C1 of the mating connector can be contacted, thereby forming a ground path.

In the aforementioned Kamata I patent, the elastic portions C1 of the shield case C are bent from the outside of the insulating case A toward the inside of the insulating case A receiving chamber A1, and the material of the insulating case C is considered to be formed. After the conditions and the technical difficulty of bending the sheet metal of each of the elastic portions C1, it is apparent that the connector disclosed in the Kamata I patent is difficult to reduce its overall height.

As shown in Fig. 14, the connector structure disclosed in U.S. Patent No. 7,150,634 (hereinafter referred to as the Kamata II patent) is a high frequency connector compatible with the connector of the Kamata I patent. The connector disclosed in the Kamata II patent includes an insulative housing A, a plurality of signal terminals B, and a shield housing C. In the Kamata II patent, the insulating housing A is used to position the relative positions of the plurality of signal terminals B, and the insulating housing A has a main body A2 portion and a tongue portion A3, the insulating housing A The tongue portion A3 is a portion having a lower height with respect to the main body portion A2 of the insulating case A, and the tongue plate A3 portion of the insulating case A extends from the main body portion A2 of the insulating case A by the insulating case A The main body portion A2 supports the tongue portion A3 of the insulating case A such that the tongue plate A3 portion of the insulating case A is kept at a distance from the top surface or the bottom surface of the main body portion A2 of the insulating case A. Each of the signal terminals B may be fixed to the main body portion A2, the tongue portion A3, or both of the insulating housing A by insert molding or by simple assembly. The opposite ends of each of the signal terminals B are respectively a connecting portion B1 and a contact portion B2, and each of the signal terminal B connecting portions B1 is connectable with a flexible circuit board (not shown in the drawing, and the flexible circuit board can be It is considered to be a cable that transmits electronic signals) to form an electrical connection.

The finger D1, E1 and the flexible circuit board Or the grounded portion of the cable forms a ground path.

In the disclosure of the Kamata II patent, each of the fingers D1, E1 is a material directly formed from the upper casing D and the lower casing E, so that the shielding casing C is inevitably caused to the insulating casing A. If the electromagnetic shielding is damaged, when the frequency of the electronic signal transmitted adjacent to the signal terminals B of the respective fingers D1 and E1 is increased, the shielded casing C having the electromagnetic shielding damage will greatly reduce the effectiveness of the electromagnetic shielding.

As shown in the fifteenth figure, the electronic connector disclosed in U.S. Patent No. 7,934,957 (hereinafter referred to as the Nakajima patent) is similar to the structure of the Kamata I patent, and only the difference between the Kamata I patent disclosure and the Nakajima patent disclosure is described below. . The connector disclosed in the Nakajima patent has no elastic portion C1 bent from the outer side of the insulating casing A toward the U-shaped inside the insulating casing A receiving chamber A1 (refer to the thirteenth figure of the Kamata I patent), and thus the Nakajima patent The disclosed connector should have a lower height than the Kamata I patent. However, the shield case C disclosed in the Nakajima patent adopts a patent structure similar to that of the Kamata II, that is, a plurality of fingers E1 extending from the shield case C material to the insulative housing A receiving chamber A1, such a shield case The body C structure gives the Nakajima patent a poor electromagnetic shielding effect.

As shown in the first figure, in the preferred embodiment of the present invention, there is a high frequency electronic connector combination that can be matched with a pair of connectors, and the electrical connection relationship established by the two connectors is matched to each other to make a high frequency. Electronic signals can be transmitted between the two (electronic) connectors. Since the connector disclosed in the preferred embodiment of the present invention is mainly used for transmitting high frequency electronic signals, the docking connector can also be considered as a high frequency electronic connector, and the "high frequency electronic connector combination" The term can be used to mean a combination of single-finger single electronic connectors and can also be used to refer to a combination of the single electronic connector and the pair of electrical connectors. For convenience of the following disclosure, the single electronic connector in the "high-frequency electronic connector assembly" is hereinafter simply referred to as a board end connector, and the docking electronic connector matching the board-end connector It is simply referred to as a cable end connector 2 (cable end connector).

As shown in the second and third figures, the board end connector 1 disclosed in the preferred embodiment of the present invention is a connector that can be mounted on a circuit board (not shown), and the connector is mainly It is composed of an insulating housing 11, a plurality of terminals 15 and a shield housing 16. The insulating housing 11 has a main body portion 111 and a tongue portion 112. The main body portion 111 of the insulating housing 11 supports the tongue portion 112. The tongue portion is supported by the main body portion 111 of the insulating housing 11. 112 is a distance from the board.

In the illustration of the preferred embodiment, each of the terminals 15 has two different width dimensions. Hereinafter, each terminal having a smaller width dimension is designated as the signal terminal 151, and each terminal having a larger width dimension is designated as a power terminal. 154. Since the types of electronic signals transmitted by the respective terminals 15 in the connector are specified according to requirements and other hardware conditions, the names of the terminals are specified in the present specification with the difference in width of the terminals for convenience of explanation. Actually, in the preferred embodiment, In the illustration, regardless of The signal terminal 151 having a small width or the power terminal 154 having a large width may still include terminals for transmitting other electronic signals, including but not limited to a ground signal, and thus the implementation of the present invention is not limited to the above-mentioned designation. Most of the signal terminals 151 and the connectors of the plurality of power terminals 154.

Since the transmission of high-frequency electronic signals is mostly dependent on differential mode transmission, the high-frequency signals transmitted by the differential mode need to form a signal channel by using at least one pair of signal terminals 151, but sometimes in order to consider high-frequency electronic signals. The electromagnetic interference effect generated during the transmission adds a grounding terminal to the electronic signal channel. Therefore, the preferred embodiment of the present invention discloses that the signal terminal 151 for transmitting the high frequency electronic signal is at least one pair and at least the pair of signals. The terminal 151 transmits the differential mode electronic signal.

In a preferred embodiment, each of the power terminals 154 is insert molded in a first auxiliary member 12, and each of the signal terminals 151 is embedded and formed in a second auxiliary member 13 and utilized. Each of the auxiliary members 12, 13 positions each of the terminals 151, 154 at an appropriate position of the insulating housing 11. Fixing the first auxiliary member 12 and the second auxiliary member 13 at an appropriate position of the insulating housing 11 can form a snap mechanism or a positioning mechanism on the main body portion 111 of the insulating housing 11 while being in the first auxiliary The member 12 and the second auxiliary member 13 are respectively provided with corresponding complementary mechanisms, whereby the first auxiliary member 12 and the second auxiliary member 13 are respectively fixed at appropriate positions of the insulating housing. In this embodiment, each of the power terminals 154 is embedded in the first auxiliary member 12, and the first auxiliary member 12 is fixed to the insulating housing 11 by a snap mechanism or a positioning mechanism. Therefore, the distance between each of the power terminals 154 and the nearest signal terminal 151 may be greater than the distance between the signal terminals 151.

Each of the power terminal 154 and each of the signal terminals 151 are respectively provided from the first and second auxiliary The connecting portions 155, 152 and a contact portion 156, 153 are exposed, and the connecting portions 155, 152 of the power terminal 154 and each of the signal terminals 151 are respectively extended from the insulating housing 11 and soldered to The power supply terminal 154 and each of the signal terminals 151 are electrically connected to the electronic circuit on the circuit board. The contact portions 156 and 153 of the power supply terminal 154 and the signal terminals 151 exposed from the first and second auxiliary members 12 and 13 are collectively arranged on a first surface of the tongue portion 112 of the insulating housing 11. 113. The contact portions 156 and 153 of the terminal 15 disposed on the tongue portion 112 of the insulating housing 11 can be electrically connected to the butted wire end connector 2 (refer to FIG. 6).

As shown in the second and fourth embodiments, in the preferred embodiment of the present invention, the contact portions 156, 153 of the terminals 15 are arranged on the first surface 113 of the tongue portion 112 of the insulative housing 11, The first surface 113 of the tongue portion 112 of the insulative housing 11 may be a surface facing the circuit board or facing away from the circuit board. Since the contact portions 156, 153 of the terminals 15 are used to establish the electrical connection between the board end connector 1 and the line end connector 2, in order to avoid the contact portions 156, 153 of the terminals 15 in the two connectors 1 Bending or deforming occurs during the matching process, and the first surface 113 of the tongue portion 112 of the insulating housing 11 of the contact portion 156, 153 of the terminal 15 may be recessed with one or more grooves 114 ( In the third figure, the contact portions 156 of the power terminals 154 share a recess 114; the contact portions 153 of the signal terminals 151 share a recess 114), so that portions of the contact portions 156, 153 of the terminals 15 are partially sunk. In the recess 114, thereby reducing or avoiding the height of the first surface 113 of the tongue portion 112 of the insulating housing 11 by the contact portions 156, 153 of the terminal 15.

In the preferred embodiment, the contact portions 156, 153 of the terminal 15 are partially sunk in the first surface 113 of the tongue portion 112 of the insulative housing 11, so in a variation of the present invention, each of the terminals The contact portions 156, 153 of the 15 are permeable to insert molding in the insulating housing 11 The portion of the tongue plate 112 is partially embedded in the first surface 113 of the tongue portion 112 of the insulative housing 11. At this time, each of the terminals 15 does not need to pass through the first auxiliary member 12 or the second auxiliary member 13 again. It is fixed at an appropriate position of the insulating housing 11. Similarly, if the terminal portion 15 is partially embedded in the material of the main body portion 111 of the insulating housing 11 when the main body portion 111 of the insulating housing 11 is formed, the contact portions 156 and 153 of the terminals 15 can still be accurately The ground is arranged at a predetermined position on the tongue portion 112 of the insulating housing 11, and at this time, the terminals 15 are not necessarily fixed to the insulating housing 11 through the first auxiliary member 12 or the second auxiliary member 13. The right place. Of course, if the contact portions 156 and 153 of the terminals 15 are completely embedded in the tongue portion 112 of the insulating case 11, each of the terminals 15 loses the function of exchanging electronic signals with the line connector 2, so The contact portions 156, 153 of the terminals 15 can only be partially embedded in the tongue portion 112 of the insulating case 11 to expose the partial contact portions 156, 153 of the terminals 15.

In the illustration, the first surface 113 of the tongue portion 112 of the insulative housing 11 is a contact portion 156, 153 in which a plurality of terminals 15 are arranged, opposite to the first surface 113 of the tongue portion 112 of the insulative housing 11. A second surface 115 is provided with a metal plate 14 such that the opposite surfaces 113, 115 of the tongue portion 112 of the insulating housing 11 are respectively provided with contact portions 156, 153 of the signal terminals 15 and the metal plate 14, the metal plate 14 Electromagnetic interference from the second surface 115 of the tongue portion 112 of the insulative housing 11 is blocked. The metal flat plate 14 is attached to the second surface 115 of the tongue portion 112 of the insulating housing 11, and the metal flat panel 14 is not damaged in the orthographic projection direction of the contact portions 153 and 156 of the signal terminal 151 and the power terminal 154. Therefore, the metal plate 14 can completely shield the electromagnetic waves outside the board end connector 1 from the second surface 115 of the tongue portion 112 of the insulative housing 11 from interfering with the contact portions 153 and 156 of the terminals 15.

In order to enable the metal plate 14 to be firmly fixed to the second surface 115 of the tongue portion 112 of the insulating housing 11, the periphery of the metal plate 14 may be provided with a plurality of flanges 141, and the flanges 141 are insulated from the flanges 141. The interference of the second surface 115 of the tongue portion 112 of the housing 11 generates friction, so that The metal flat plate 14 can be stably fixed to the second surface 115 of the tongue portion 112 of the insulating housing 11. Since the present invention is mainly applied to a low-frequency small-pitch high-frequency electronic connector, the metal flat plate 14 in the board-end connector 1 is attached to the second surface 115 of the tongue portion 112 of the insulating housing 11. Therefore, the second surface 115 of the tongue portion 112 of the insulating housing 11 may be provided with a slot in consideration of reducing or avoiding the size of the metal plate 14 protruding from the second surface 115 of the tongue portion 112 of the insulating housing 11. The metal plate 14 is at least partially received to reduce the size of the metal plate 14 protruding from the second surface 115 of the tongue portion 112 of the insulating housing 11. At this time, the metal plate 14 can be regarded as being exposed to the insulating housing. 11 The inside of the second surface 115 of the tongue portion 112 is recessed 116. In the preferred embodiment of the present invention, the metal plate 14 is partially exposed in the notch 116 of the second surface 115 of the tongue portion 112 of the insulating housing 11, but the metal plate 14 is mainly for the board connector 1 The function of the present invention is to provide electromagnetic shielding. Therefore, in the modified embodiment of the present invention, the metal plate 14 may not be exposed at all to the second surface 115 of the tongue portion 112 of the insulating housing 11, and the metal plate 14 still has electromagnetic The function of shielding.

As shown in the third, fourth and fifth figures, the metal flat plate 14 is directly formed into a part of the insulating housing 11 by insert molding, so that the metal flat plate 14 has a plurality of flanges 141 in addition to the foregoing. And having a through hole 142 and a plurality of claws 143, when the insulating housing 11 is formed, the material of the insulating housing 11 can be filled in the through hole 142 of the metal flat plate 14 and the periphery of each of the hooks 143, thereby forming The frictional force of the metal plate 14 on the insulating housing 11. It is difficult to consider the forming technique of the tongue portion 112 of the insulating housing 11. The perforations 142 of the metal plate 14 and the positions of the hooks 143 should be disposed as far as possible to avoid the orthographic projection positions of the contact portions 153 and 156 of the terminals 15. The formation of the tongue portion 112 of the insulating housing 11 is difficult, and even the risk of short circuiting of the specific terminal 15 and the metal flat plate 14 is caused. In the preferred embodiment of the present invention, the metal plate 14 is formed by insert molding. It is bonded to the material of the tongue portion 112 and the main body portion 111 of the insulating housing 11; however, the metal flat plate 14 does not necessarily have to use the insert molding method and the material of the tongue portion 112 and the main body portion 111 of the insulating housing 11. In combination, a conventional assembly or a portion in which the metal flat plate 14 is embedded in the main body portion 111 or the tongue portion 112 of the insulating housing 11 is a viable change.

Due to the miniaturization of the dimensions of the tongue portion 112 of the insulative housing 11 in the low-height high-frequency connector disclosed in the drawings, the mechanical strength of the tongue portion 112 of the insulative housing 11 may be due to the size. And being deteriorated, even if the tongue portion 112 of the insulating housing 11 is damaged due to improper force during the matching with the wire end connector 2 (refer to the first figure), the metal plate disclosed in the present application 14 can be considered as a suitable mechanical reinforcement for the tongue portion 112 of the insulative housing 11. In order to enhance the overall benefit of the metal plate 14 to the board end connector 1 , at least one end of the metal plate 14 adjacent to the circuit board (not shown) extends toward the circuit board (in the third figure) For each of the three grounding legs 144, each of the grounding pins 144 is electrically coupled to a suitable circuit on the circuit board such that the metal plate 14 can be considered to be a partial extension of the electronic circuitry on the circuit board, particularly a grounding circuit.

Each of the terminals 22 can be easily divided into a signal terminal 221 and a power terminal 224 according to the difference in size of the outer shape, and each of the signal terminals 221 can transmit a high frequency electronic signal in pairs. The opposite ends of each of the terminals 22 are respectively a contact portion 223, 226 and a connecting portion 222, 225, and the connecting portions 222, 225 of the terminals 22 are electrically connected to the inner circuit board 25, respectively, by the inner circuit board The circuit on 25 (not shown) is electrically coupled to a set of cable lines 26.

In the eighth embodiment, each of the signal terminals 221 is insert molded in a third auxiliary member 213, and the third auxiliary member 213 is fixed to the insulating housing 21 through a snap mechanism. The upper position is thereby positioned to position each of the signal terminals 221 at a predetermined position of the insulating housing 21. Each of the power terminals 224 is interfered with each other by the respective power terminals 224 and the insulating case 21 by a conventional assembly method, and each of the power terminals 224 is fixed to the insulating case 21 by the interference.

According to the foregoing disclosure, it can be inferred that in the structures of the connectors 1 and 2 disclosed in the present application, at least the embedded molding method or the conventional assembly interference method can be used for fixing the terminals to the insulating housing, and it is not limited to the use of the embedded molding method.

In order to protect the signal terminals 221 of the line connector 2 and the contact portions 223 and 226 of the power terminals 224, the contact portions 223 and 226 of the insulating housing 21 with respect to the signal terminals 221 and the power terminals 224. One or more recesses 212 (in the figure, a plurality of recesses) are provided, so that the contact portions 223, 226 of the signal terminals 221 and the power terminals 224 can partially sink into the recesses of the insulating housing 21. In 212, the contact portions 223 and 226 of the terminal 22 are prevented from being permanently deformed by an external force.
