[0003] However, in such a hybrid connector, because the signal contacts are too close to the power contacts, the signals transmitted by the signal contacts can be adversely affected by the voltage or current applied to the power contacts, resulting in noise, distortion or errors of the signals. SUMMARY

[0004] One of the objects of the utility model is to provide a hybrid connector assembly capable of preventing the signals transmitted by the signal contacts from being affected by the voltage or current applied to the power contacts.

[0005] According to an embodiment of the utility model, a hybrid connector is provided, comprising an insulating housing, a plurality of power contacts and a plurality of signal contacts, the hybrid connector being fitted with a connection object in a first direction, the plurality of power contacts and the plurality of signal contacts being held by the insulating housing and arranged in a second direction perpendicular to the first direction;

[0006] The plurality of power contacts comprises at least one ground power contact and a plurality of non-ground power contacts, the at least one ground power contact being arranged between the plurality of non-ground power contacts and the plurality of signal contacts;

[0007] The distance between the at least one ground power contact and the adjacent signal contact in the plurality of signal contacts in the second direction is set to be greater than or equal to 7.1 mm, and the distance between the at least one ground power contact and the adjacent non-ground power contact in the plurality of non-ground power contacts in the second direction is set to be greater than or equal to 7.1 mm.

[0008] According to the hybrid connector of the utility model, the distance between two adjacent non-ground power contacts in the plurality of non-ground power contacts in the second direction is set to be greater than or equal to 3.9 mm.

[0009] According to the hybrid connector of the utility model, the plurality of power contacts and the plurality of signal contacts are arranged in two columns in the second direction.

[0010] According to the present invention, the hybrid connector includes a power mating portion and a signal mating portion, the power mating portion and the signal mating portion being arranged along the second direction, the plurality of power contacts being disposed in the power mating portion, and the plurality of signal contacts being disposed in the signal mating portion.

[0011] According to the hybrid connector of this utility model, the power mating part and the signal mating part are female mating parts.

[0012] According to the hybrid connector of this invention, the power mating portion and the signal mating portion are separated by a partition wall.

[0013] According to the hybrid connector of this utility model, the plurality of ungrounded power contacts include energized power contacts and neutral power contacts.

[0014] According to the hybrid connector of this utility model, the non-grounded power contact adjacent to the at least one grounded power contact is either the live power contact or the neutral power contact.

[0015] According to the hybrid connector of this utility model, the object to be connected is a board, and the board has multiple conductive pads formed on the edge of the insertion end.

[0016] According to the hybrid connector of this invention, the width of each power contact in the second direction is greater than the width of each signal contact in the second direction.

[0017] By separating the signal contact from the power contact by a certain distance and positioning the grounding power contact between the signal contact and the ungrounded power contact, the signal transmitted by the signal contact can be prevented from being affected by the voltage or current applied to the power contact. This ensures the quality of the signal transmitted by the signal contact even under rapid changes in the voltage or current applied to the power contact.

[0060] The lockable connector assembly according to an embodiment of the present invention will be described below with reference to the accompanying drawings. In the drawings, the same elements or elements having the same function are labeled with the same reference numerals. The drawings are not drawn to scale.

[0061] Reference Figures 1 to 4 This describes a hybrid connector according to an embodiment of the present invention. Figure 1 This is a perspective view of a hybrid connector according to an embodiment of the present invention. Figure 2 This is a view showing the card plate, which is the object of connection, mated with the hybrid connector. Figure 3 This is a view of the graphics card board not being fitted with the hybrid connector. Figure 4 This is an exploded perspective view of a hybrid connector according to an embodiment of the present invention. Figure 4 In the image, a power contact and a signal contact are shown magnified. The hybrid connector is generally designated as component number 10. The hybrid connector 10 is specifically implemented as a hybrid edge connector. In this embodiment, the hybrid connector 10 is mounted on the circuit board 30, and the card plate 20, as the connection object, can be fitted with the hybrid connector 10 along the first direction D1. The card plate 20 has a plurality of power conductive pads 21 and a plurality of signal conductive pads 22 formed near the edge of the insertion end. The insertion end of the card plate 20 has a notch 23 as a foolproof structure, allowing the card plate 20 to be inserted into the hybrid connector 10 only in a specified orientation.

[0062] like Figure 1 and Figure 4 As shown, the hybrid connector as a whole includes an insulating housing 11, multiple power contacts 12, multiple signal contacts 13, and two clamping members 14.

[0063] The insulating housing 11 is made of insulating synthetic resin or polymer material by injection molding. The insulating housing 11 includes a power supply mating portion 110A and a signal mating portion 110B. The power supply mating portion 110A and the signal mating portion 110B are mating portions. The power supply mating portion 110A and the signal mating portion 110B are arranged along a second direction D2 perpendicular to the first direction D1. A power contact 12 is disposed in the power supply mating portion 110A, and a signal contact 13 is disposed in the signal mating portion 110B.

[0064] The power contact 12 and signal contact 13 may be made of copper or a copper alloy. The power contact 12 and signal contact 13 are arranged in two rows along the second direction D2. The two rows of contacts are spaced apart from each other in a third direction D3 perpendicular to the first direction D1 and the second direction D2. The power contact 12 includes a solder portion 120, a first holding portion 121 extending from the solder portion 120, a second holding portion 122 offset from the first holding portion 121, a spring arm 123 extending from the second holding portion 122, and a contact portion 124 formed at the end of the spring arm 123. The first holding portion 121 and the second holding portion 122 each have a barb structure and are inserted into a holding hole or holding groove (not shown) formed in the insulating housing 11 in an interference fit manner. In this embodiment, the solder portion 120 is made in the shape of a needle.

[0065] The signal contact 13 includes a soldering portion 130, a retaining portion 131 extending from the soldering portion 130, a spring arm 132 extending from the retaining portion 131, and a contact portion 133 formed at the end of the spring arm 132. The retaining portion 131 has a barbed structure and is inserted into a retaining hole or retaining groove (not shown) formed in the insulating housing 11 in an interference fit. In this embodiment, the soldering portion 130 is configured to be suitable for surface mounting soldering onto a pad on a circuit board.

[0066] In order to transmit power, especially high power, through the power contact 12, the power contact 12 is made such that its width in the second direction D2 is greater than the width of the signal contact 13 in the second direction D2.

[0067] The clamping member 14 may be made of metal or alloy material (e.g., stainless steel). The clamping member 14 has a flat body portion 140 and a welding portion 141. The body portion 140 has a barbed structure and is inserted into a retaining groove 111 formed at the end of the insulating housing 11 in an interference fit manner. By soldering the welding portion 141 of the clamping member 14 to the solder pads of the circuit board, the hybrid connector 10 can be securely fixed to the circuit board.

[0068] Figure 5This is a top view of a hybrid connector according to an embodiment of the present invention. According to the hybrid connector 10 of the present invention, the power contact 12 can be used to transmit alternating current. The power contact 12 includes a grounding power contact 12A, a neutral power contact 12B, and a live power contact 12C. The neutral power contact 12B and the live power contact 12C are ungrounded power contacts. The grounding power contact 12A is disposed between the ungrounded power contacts (i.e., the neutral power contact 12B and the live power contact 12C) and the signal contact 13. The grounding power contact 12A has a shielding function, isolating the signal contact 13 from the ungrounded power contacts.

[0069] The distance d1 between the grounding power contact 12A and the adjacent signal contact 13 (i.e., the outermost signal contact on the left) is set to 7.1 mm or more. The distance d2 between the grounding power contact 12A and the adjacent ungrounded power contact (i.e., the neutral power contact 12B in this embodiment) is set to 7.1 mm or more. The distance d3 between two adjacent ungrounded power contacts (i.e., the neutral power contact 12B and the energized power contact 12C) is set to 3.9 mm or more. The above-mentioned distances are measured from the center of the contact.

[0070] It should be understood that the positions of the neutral power contact 12B and the live power contact 12C are interchangeable. In other variations, the non-grounded power contact adjacent to the grounded power contact 12A can be a live power contact.

[0071] Figure 6 It is along Figure 5 The cross-section taken by line AA in the diagram. For example... Figure 5 As shown, the power engagement portion 110A and the signal engagement portion 110B are separated by a partition wall 112. The partition wall 112 is offset from the center of the insulating housing 11 in the second direction D2. As a foolproof structure, the partition wall 112 can engage with the notch 23 of the card plate 20. Therefore, it can be ensured that the connected object, such as a mating connector or card plate, can be inserted into the hybrid connector 10 in a specified orientation.

[0072] The contact arrangement described above effectively prevents the signal transmitted by the signal contacts from being affected by the voltage or current applied to the power contacts. Even in cases where the voltage or current of the power contacts rises sharply, such as due to a lightning strike, the hybrid connector according to this invention ensures the signal quality transmitted by the signal contacts.

[0073] Although this utility model has been described and demonstrated with reference to preferred embodiments, it should be understood that many variations and modifications can be made by those skilled in the art without departing from the spirit and scope of this utility model. Therefore, this utility model is not limited to the disclosed embodiments, but is subject to the wording of the claims, that is, any equivalent variations and modifications made without departing from the claims of this utility model should still fall within the scope of this utility model.
