Description

Connector and device comprising the same

Technical Field

The present utility model relates to a connector and a device including the same.

Background

A connector is a device for connecting two active devices to transmit current or signals. The connector can simplify the assembly process of the electronic product and also simplify the mass production process of the electronic product. The connector is easy to maintain, and if a certain electronic component fails, the failed component can be quickly replaced under the condition of being provided with the connector; with the technical progress, the electronic product with the connector can update the electronic element, and the new electronic element with better performance is used for replacing the old electronic element, thereby being convenient for updating; connectors can improve flexibility in product design when designing and integrating new products, as well as when composing systems from electronic components. Therefore, the connector is widely applied to the fields of traffic, medical treatment, aerospace, military, household appliances and the like.

The basic performance of connectors can be divided into three general categories: i.e. mechanical properties, electrical properties and environmental properties.

The insertion and extraction forces and the mechanical life are important mechanical properties. The insertion and extraction forces and mechanical life of the connector are related to the contact structure (positive pressure magnitude), the contact site plating quality (sliding friction coefficient), and the dimensional accuracy (alignment) of the contact arrangement.

The main electrical properties of the connector include contact resistance, insulation resistance and electrical resistance. Wherein high quality electrical connectors should have low and stable contact resistance, the contact resistance of the connector varying from a few milliohms to tens of milliohms; insulation resistance is an indicator of the insulation performance between contacts and a housing of an electrical connector, the insulation resistance being on the order of hundreds to thousands of megaohms; the dielectric strength is an indication of the ability of the connector to withstand a rated test voltage between contacts or between a contact and a housing.

Environmental properties include temperature resistance, moisture resistance, salt spray resistance, vibration resistance, impact resistance, and the like.

The development of connector technology has exhibited the following characteristics: the signal transmission has high speed and digital, the integration of various signal transmission, the miniaturization of product volume, the low cost of product, the module combination, the convenience of plug and the like.

In existing connectors having at least one row of terminals, the signal terminals of each row of terminals are typically exposed, resulting in signal interference between the signal terminals of each row of terminals, limiting the improvement in signal integrity. The ground terminals located between the signal terminals of each row of terminals do not shield well the signal interference between adjacent signal terminals, further limiting the improvement in signal integrity, resulting in existing connectors not being used in areas where high demands are placed on signal integrity.

The present utility model discloses a connector 1000 (see fig. 1 to 8) and a device (not shown in the drawings) including the connector 1000.

The connector 1000 includes: the connector comprises a housing 100, at least one row of terminals 200 mounted in the housing 100, a holder 500 mounted in the housing 100, at least one row of cables 300 and at least one grounding member 400, wherein each row of terminals 200 in the at least one row of terminals 200 is respectively arranged on one holder 500.

Each row of terminals 200 includes at least one pair of signal terminals 210 and ground terminals 220 located on either side of each pair of signal terminals 210. To the terminals 200, cables 300 are connected, each cable 300 including a pair of ground wires 320 and a pair of signal wires 310 respectively connected to each pair of signal terminals 210. The ground 400 at least partially covers and is spaced apart from the electrical connection portion of the signal terminal 210 and the signal line 310 and is electrically connected with the ground terminal 220, which not only greatly shields electromagnetic waves (i.e., signal interference) radiated to the outside by the covered signal terminal 210 and the signal line 310, but also greatly shields influence (i.e., signal interference) of the external electromagnetic waves on the covered signal terminal 210 and the signal line 31O, effectively improving signal integrity of the connector 1000.

Referring to fig. 5 to 7, the ground wire 320 of the cable 300 is electrically connected to the ground terminal 220 via the ground 400. Referring to fig. 8, the ground member 400 is a unitary member configured in a wave shape having alternately distributed peaks and valleys such that the ground member 400 forms at least two contact points with each of the ground terminals 220 in the longitudinal direction L (i.e., two contact points formed with the ground terminals 220 by the first and second ground arm portions 420 and 430, respectively, mentioned below). Thus, the ground terminals 220 of each row of terminals 200 and the ground wires 320 of each row of cables 300 are electrically connected together by the same integral component (i.e., ground 400), which greatly shortens the signal return path, further effectively improving the signal integrity of the connector 1000.

With continued reference to fig. 5-8, each ground 400 includes at least one ground cell, each ground cell including: a flat ground plate 410 extends in the longitudinal direction L along each pair of signal terminals 210 and each pair of signal lines 310 connected to each pair of signal terminals 210 to at least partially overlie each pair of signal terminals 210 and each pair of signal lines 310 and to be spaced apart from each pair of signal terminals 210 and each pair of signal lines 310. The flat ground plate 410 constitutes the wave-shaped peak described above.

With continued reference to fig. 5-8, each ground unit further includes: the first ground arm portions 420 extend downward from one end 411 of the ground plate 410 laterally (i.e., in a lateral direction T transverse to the longitudinal direction L, see fig. 6 to 8) to the adjacent ground terminal 220 and are integrally formed with the first ground arm portions 420 of the adjacent ground units, respectively, such that each first ground arm portion 420 abuts between the ground terminal 220 and the corresponding ground wire 320. Adjacent two first grounding arms 420 connected together constitute a part of the trough of the above-mentioned wave shape.

Referring to fig. 4 to 7, the holder 500 includes: at least one first retaining portion 510 and at least one pair of second retaining portions 520. Each pair of signal terminals 210 extends through the first holding portion 510 and is fixed by the first holding portion 510. At least one pair of second holding portions 520 are respectively located at both sides of each first holding portion 510 and protrude beyond (i.e., higher than) the first holding portion 510, and each ground terminal 220 extends through the second holding portion 520 and is fixed by the second holding portion 520. The flat ground plate 410 extends through the holder 500 between the pair of second holders 520 and above the first holders 510 between the pair of second holders 520 and is spaced apart from the first holders 510, and the ground plate 410 has a height lower than the height of the pair of second holders 520. That is, each ground plate 410 extends across the holder 500 between each pair of second holders 520 and covers the first holders 510.

With continued reference to fig. 4-8, each ground unit further includes: the second ground arm portions 430 extend downward from the other ends 412 of the ground plates 410 laterally (i.e., in a lateral direction T transverse to the longitudinal direction L, see fig. 6 to 8) to the portions 221 (see fig. 7) of the adjacent ground terminals 220 exposed on the corresponding second holding portions 520, respectively, and are integrally formed with the second ground arm portions 430 of the adjacent ground units. The adjacent two second grounding arm portions 430 connected together constitute another part of the trough of the above-described wave shape, and are spaced apart from the adjacent two first grounding arm portions 420 connected together in the longitudinal direction L (see fig. 8) to accommodate one second holding portion 520 in the space. The presence of the valleys not only achieves two contact points formed by the first and second ground arms 420 and 430, respectively, with the ground terminals 220, but also greatly shields the adjacent pair of signal terminals 210 from signal interference with each other, further improving the signal integrity of the connector 1000.

Referring to fig. 2 to 4, 6 and 8, the ground plate 410 is provided with an extension 4111 protruding from the one end 411 to partially cover the insulation sheath of a corresponding one of the cables 300 to further reduce signal interference from the signal wires 310 of the cables 300 exposed outside the insulation sheath.

In one embodiment according to the present utility model (see fig. 2 to 3), the at least one row of terminals 200 includes two rows of terminals 200 arranged to face each other, the at least one row of cables 300 includes two rows of cables 300 arranged to be connected to the two rows of terminals 200, respectively, the at least one grounding member 400 includes two grounding members 400 arranged on the two rows of terminals 200, respectively, between the two rows of terminals 200, and the two holding members 500 are provided with at least one of protrusions 521 and recesses 522 capable of being cooperatively connected to each other, respectively, on the second holding portion 520 such that the two holding members 500 can be cooperatively connected to each other to arrange the two rows of terminals 200 fixed to the two holding members 500 in the housing 100 opposite to each other.

However, it should be understood by those skilled in the art that the present utility model is not limited thereto, and the at least one row of terminals 200 may also include a plurality of rows of terminals 200, and the at least one row of cables 300 may also include a plurality of rows of cables 300.
