DETAILED DESCRIPTION OF THE EMBODIMENTS
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
A connector according to an embodiment of the present disclosure includes an insulation body, a plurality of signal terminals held in the insulation body for transmitting signals, and a plurality of power supply terminals held in the insulation body for supplying power. The power supply terminals of the connector are adapted to engage with power supply terminals of another mating connector such that the power supply terminals engaged together are connected in parallel.
According to another embodiment of the present disclosure, a connector assembly includes two of the abovementioned connectors. The power supply terminals of either one of the two connectors are engaged with the power supply terminals of the other one of the two connectors, and the power supply terminals engaged together are connected in parallel when the two connectors are mated together.
As shown in FIGS. 1, 2, 4 and 7, each of the connectors 100, 100′ (i.e., a connector and a mating connector) according to embodiments of the present disclosure includes an insulation body 10, a plurality of signal terminals 20 and a plurality of power supply terminals 30. The plurality of signal terminals 20 are held in the insulation body 10 and are adapted to transmit signals. The plurality of power supply terminals 30 are held in the insulation body 10 and adapted to supply power. When two connectors are mated, the power supply terminals 30 of either one of the two connectors 100, 100′ are adapted to engage with the power supply terminals of the other one of the two connectors. The plurality of pairs of power supply terminals 30 engaged together are connected in parallel to provide a relatively large current, such as 100 amperes or higher.
In an exemplary embodiment, a height of the power supply terminal 30 of the connector 100,100′ extending from the insulation body 10 along a mating direction Z toward the other connector 100, 100′ is the same as a height of the signal terminal 20 extending from the insulation body along the mating direction Z toward the other connector 100, 100′, thereby keeping the height of the connector assembly minimized while transmitting relatively the large current.
In an exemplary embodiment, the insulation body 10 is provided with a plurality of first slots 12. The plurality of first slots 12 are arranged in at least one row along a width direction Y of the insulation body 10. The plurality of signal terminals 20 are positioned on both sides of each row of the first slots 12.
In an exemplary embodiment, as shown in FIGS. 11 and 12, each power supply terminal includes a pin 31, a plurality of electrical contact points 38, and a connecting portion 37 connected between the pin and the plurality of electrical contact points. When the two connectors 100, 100′ are mated, the plurality of electrical contact points 38 of the power supply terminal 33 of either one of the two connectors are adapted to be in contact with the plurality of electrical contact points of the power supply terminal of the other or mating connector. In this way, the plurality of electrical contact points 38 can greatly improve the contact stability when transmitting the large current. As shown in FIG. 12, a section of the connecting portion 37 close to the electrical contact points 38 has an arc structure 39 in order to reduce an insertion and extraction force during the insertion and extraction process of the two connectors 100, 100′.
In an exemplary embodiment, as shown in FIG. 11, the pin 31 includes a middle pin 31a and a side pin 31b located on either side of the middle pin. Two side pins 31b are shown in this embodiment. However, in some other embodiments of the present disclosure, only one side pin 31b may be provided on one side of the middle pin 31a.
In an exemplary embodiment, as shown in FIGS. 9 and 10, the connector 100, 100′ further includes a welding ball 50 connected to the pin 31 of the corresponding power supply terminal 30. As shown in FIGS. 8-10, the connector 100, 100′ further includes a spacer 40 made of, for example, insulating materials such as plastic. The spacer 40 is attached to a side of the insulation body 10 away from the other connector 100′, 100 and has a physical portion positioned between the adjacent welding balls 50. Specifically, as shown, the spacer 40 may be a plate-like member having a plurality of separated accommodating holes 41, with one welding ball 50 is accommodated in each accommodating hole. The welding ball 50 has a welding portion exposed from the accommodating hole 40 to be welded to the circuit board. In some examples, the portion of each welding ball 50 connected to the pin 31 is at least partially positioned within the accommodating hole 41. For example, except for the welding portion, other portions of the welding ball 50 are housed or surrounded in the corresponding accommodating hole 41 so that the welding balls are separated from each other. The spacer 40 may be, for example, fixed to the insulation body 10 by the riveting member 60.
In an exemplary embodiment, as shown in FIG. 10, the middle pin 31a is formed with a locking portion 36 adapted to interfere with the spacer 40 to prevent the spacer from being separated from the insulation body 10 of the connector 100,100′. This locking portion 36 may, for example, adopt a barbed structure. In such embodiment, an outer edge of the spacer 40 is thermally riveted on the insulation body 10, and the locking portion 36 on the middle pin 31a interferes with the spacer so that an inner portion of the spacer can be reliably attached to the insulation body. This avoids the occurrence of an excessive gap between the spacer 40 and the insulation body 10 due to warping of the spacer after the reflow soldering process (the product will be soldered on the customer's PCB by the reflow soldering process when used by the customer), which in turn affects the coplanarity and signal integrity (SI) performance of the welding ball 50.
In an exemplary embodiment, as shown in FIG. 3, each power supply terminal 30 includes a pin 31 and an electrical contact portion 32 extending therefrom. A free end of the electrical contact portion 32 is formed with a raised elastic contact portion 33. When the two connectors 100, 100′ are mated, the elastic contact portion 33 of the power supply terminal 30 of either one of the two connectors is adapted to be in electrical contact with the electrical contact portion 32 of the power supply terminal of the other connector.
In an exemplary embodiment, as shown in FIGS. 1, 2 and 7, the insulation body 10 is provided with a plurality of second slots 13. The plurality of second slots 13 are divided into two groups. The two groups of second slots 13 are symmetrically located on both sides of the plurality of first slots 12 along a length direction X of the insulation body 10 and arranged in at least one row along the width direction Y of the insulation body. The plurality of power supply terminals 30 are located on both sides of each row of second slots 13. In this way, the two connectors 100, 100′ can have exactly the same structure, that is, the connectors have a hermaphrodite structure, so there is no need to manufacture two different connectors for mating. This simplifies required tooling and molds, and reduces the manufacturing cost of the connector assembly. It should be noted that, in some other exemplary embodiments, the second slots 13 may also be located in the middle or other sections of the insulation body 10 in the length direction X.
As shown in FIGS. 4-6, the power supply terminals 30 include a first power supply terminal 30a and a second power supply terminal 30b. When the two connectors 100, 100′ are mated, the first power supply terminal 30a of either one of the two connectors 100, 100′ is adapted to engage with the second power supply terminal 30b of the other connector. In other words, the first power supply terminal 30a of the connector 100 is engaged with the second power supply terminal 30b of the other connector 100′, and the second power supply terminal 30b of the connector 100 is engaged with the first power supply terminal 30a of the other connector 100′. The plurality of pairs of first power supply terminals 30a and second power supply terminals 30b engaged together are connected in parallel to provide a relatively large current carrying capacity, such as 100 amperes or higher. In an exemplary embodiment, as shown in FIGS. 4 and 5, the size and structure of the second power supply terminal 30b are exactly the same as those of the signal terminal 20. In other words, the second power supply terminal 30b can be replaced by the signal terminal 20.
Referring to FIG. 4, the first power supply terminal 30a is made of a plate with high conductivity, for example, a copper plate. The first power supply terminal 30a includes a first plate-like portion 30a1 and a second plate-like portion 30a2 stacked with the first plate-like portion. The first plate-like portion 30a1 and the second plate-like portion 30a2 each include a pin 31 and an electrical contact portion 32 extending therefrom. In this way, a thickness of the first power supply terminal 30a can be increased so as to transmit the relatively large current.
The first plate-like portion 30a1 and the second plate-like portion 30a2 each include an abutting section 34 located between the pin 31 and the electrical contact portion 32. The abutting section 34 is abutted against the insulation body 10 for fixing of the first supply terminal 30a, when the first supply terminal is in place in the insulation body 10. In an exemplary embodiment, the first power supply terminal 30a is formed in one piece. For example, it can be integrally formed from a copper plate by a stamping process, so as to reduce manufacturing costs.
The insulation body 10 is provided with a plurality of second slots 13. The plurality of second slots 13 are located on one side of the plurality of first slots 12 along the length direction X of the insulation body 10 and arranged in at least one row along the width direction Y of the insulation body. The plurality of power supply terminals 30 are located on both sides of each row of second slots 13. In this way, the two connectors 100,100′ for mating can have exactly the same structure (i.e., a hermaphrodite structure), thereby reducing the manufacturing cost of the connector assembly.
In the illustrated exemplary embodiments, the plurality of signal terminals 20 and the plurality of power supply terminals 30 are inserted in the insulation body 10. However, it should be understood that the plurality of signal terminals 20 and the plurality of power supply terminals 30 can also be fixed in the insulation body 10 by other means.
In an exemplary embodiment, as shown in FIGS. 1, 2 and 4, the insulation body 10 has a first end along the length direction X thereof and a second end opposite to the first end. The insulation body 10 is provided with at least one guiding structure configured to guide a mating of either one of the two connectors 100, 100′ to the other connector. The guiding structure includes a guiding groove 14 and a guiding column 15. The guiding groove 14 is formed at a first end of the insulation body 10 and extends in a direction perpendicular to the insulation body. The guiding column 15 is formed at the second end of the insulation body 10. When the connector 100 is mated with the other connector 100′, the guiding column 15 of the connector is adapted to engage the guiding groove 14 of the other connector, and the guiding groove 14 of the connector is adapted to engage the guiding column 15 of the other connector. In the exemplary embodiment, the number of the guiding grooves 14 is two. The two guiding grooves 14 are arranged at intervals in the width direction Y of the insulation body 10. Each guiding groove 14 defines an elongated hole having a length direction parallel to the width direction Y of the insulation body. It should be noted that, in some other embodiments of the present disclosure, the guiding groove 14 may also be a circular hole or an oval hole or the like.
According to another aspect of the present disclosure, a connector assembly includes two of the abovementioned connectors. The power supply terminals of either one of the two connectors are engaged with the power supply terminals of the other one of the two connectors. The power supply terminals engaged together are connected in parallel when the two connectors are mated together. The height of the connector assembly in the mating direction Z of the two connectors can be adjusted, for example, according to customer requirements.
According to the connector and the connector assembly of the forgoing various embodiments of the present disclosure, when the two connectors are mated the power supply terminals of the two connectors are engaged in pairs, and the plurality of pairs of engaged power supply terminals are connected in parallel to provide the relatively large current carrying capacity. In addition, the height of the power supply terminal of the connector extending from the insulation body along the mating direction toward the other connector is the same as the height of the signal terminals extending from the insulation body along the mating direction toward the other connector. This arrangement keeps the height of the connector relatively low while maximizing the current carrying capacity. Further, the connector has a hermaphroditic structure, so there is no need to manufacture two different connectors for mating, thus simplifying the mold and reducing the manufacturing cost of the connector. While the connector can transmit high-speed signals, it can also be used for power supplies, thus realizing the function of the hybrid connector. Embodiments of the present disclosure are also capable of meeting important commercial standards, such those required for UL1977 certification. In addition, the connector can increase or decrease the number of power supply terminals according to the application of different customers to realize the transmission of varied amounts of current.
