Description

Connector with a plurality of connectors

Technical Field

The present application relates to a connector.

Background

In order to effectively prevent electromagnetic interference or leakage of electromagnetic waves when a connector is assembled with a counterpart connector to establish electrical connection, the connector is required to have certain electromagnetic compatibility (EMC).

Embodiments of the present application provide a connector that includes a housing 10, conductive terminals 20, and a shield 30. The housing 10 defines a receiving cavity 103. The conductive terminals 20 are accommodated in the accommodation cavities 103 and are adapted to be electrically connected with a counterpart connector. The shield 30 is accommodated in the accommodation chamber 103 and surrounds the conductive terminal 20 in the circumferential direction but does not electrically contact the conductive terminal. The shielding member 30 is formed with a plurality of first ground anchors 301 including a first group of first ground anchors formed of a plurality of first ground anchors arranged in a first direction X and a second group of first ground anchors formed of a plurality of first ground anchors arranged in a second direction Y different from the first direction X, with a gap G between the first group of first ground anchors and the second group of first ground anchors in the circumferential direction. The shield 30 is also formed with a second ground leg 303 arranged in the gap G in the circumferential direction such that the plurality of first ground legs 301 and the second ground leg 303 surround the conductive terminal 20 in the circumferential direction.

As best shown in fig. 1, the housing 10 comprises a base plate 101 perpendicular to the axial direction Z of the connector and a housing wall 102 extending from the base plate 101 in the axial direction Z, said base plate 101 and housing wall 102 together defining a receiving cavity 103 adapted to receive said conductive terminals 20 and shields 30. The conductive terminals 20 are adapted to extend through the substrate 101 in the axial direction Z so as to establish an electrical connection with a mating connector.

As best shown in fig. 2 and 3, the side of the substrate 101 opposite the receiving cavity 103 is adapted to mate to a circuit board of a mating connector and has a contact surface 1011 adapted to contact the circuit board.

A gap G exists between the first group of first ground engaging legs and the second group of first ground engaging legs in the circumferential direction. In the conventional design, the gap G may cause electromagnetic interference to the conductive terminal 20 or leakage of electromagnetic waves from the gap G, thereby making the electromagnetic compatibility EMC of the connector poor.

In various embodiments of the present application, the shield 30 of the connector according to the present application is further formed with the second ground leg 303 arranged in the gap G in the circumferential direction such that the plurality of first ground legs 301 and the second ground leg 303 together encircle the conductive terminal 20 in the circumferential direction, thereby preventing electromagnetic interference or leakage of electromagnetic waves due to the gap G.

As best shown in fig. 5, the shield 30 includes a shield body 300 having a polygonal cross-sectional shape. The shield body 300 extends along the axial direction Z of the connector and has a plurality of

A first side of the polygonal cross-sectional shape of the shield body 300 may be defined by a first sidewall 3041 and a second side of the polygonal cross-sectional shape may be defined by a second sidewall 3043, wherein the second side may be shorter than the first side.

As best shown in fig. 4 to 6, the first ground leg 301 may have a first insertion portion 3012 adapted to be inserted in a first through hole 1021 in the substrate 101 and a first contact portion 3013 adapted to contact a ground portion on a circuit board of a counterpart connector, wherein the first insertion portion 3012 extends substantially in an axial direction, and the first contact portion 3013 extends bending from the first insertion portion.

In one embodiment, as shown in fig. 6, the first contact portion 3013 may have a first fixing hole 3014 such that the first contact portion 3013 is fixed to the contact surface 1011 of the substrate 101 by means of a fastener (e.g., a screw) passing through the first fixing hole 3014.

In addition, as shown in fig. 6, the first grounding pin 301 may further include a first extension 3011 bent from an edge of the first sidewall 3041 to extend outward to the first plugging portion 3012.

As best shown in fig. 4 to 6, the second grounding pin 303 has a second plug portion 3032 adapted to be plugged into a second through hole 1023 in the substrate 101. The second plug portion 3032 may extend generally in an axial direction and have a free end adapted to contact a ground on a circuit board. As best shown in fig. 5 and 6, the second ground leg 303 may further include a second extension 3031 bent outwardly from an edge of the second sidewall 3043 of the shield to extend to the second plug portion 3032.

As best shown in fig. 6 and 7, the second plug portion 3032 may have a protrusion 3033 extending in the axial direction Z from an edge of a free end of the second plug portion. The protrusion 3033 may be configured to extend beyond the contact surface 1011 of the substrate 101 so as to be able to contact a ground on the circuit board.

As best shown in fig. 6 and 7, the second plug portion 3032 may also have a cutout 3034. The cutout 3034 may be positioned to align with the position of the protrusion 3033 in the axial direction Z such that the protrusion 3033 and the cutout 3034 cooperate to increase the elasticity of the second plug portion 3032 for contact with the ground on the circuit board. In the illustrated preferred embodiment, the side of the hole 3034 facing the protrusion 3033 has a circular arc shape, thereby further increasing the elasticity of the second plug portion 3032 in contact with the ground portion.

As best shown in fig. 7-8, the second plug portion 3032 may also have a tab 3035 facing away from the protrusion 3033 and extending out of the plane in which the second plug portion lies. Accordingly, as shown in fig. 8, an inner surface of the base plate 101 adapted to be inserted into the second through hole 1023 of the second plug portion 3032 may form a limiting step 1024. Thus, the tab 3035 abuts the stop step 1024 after the second plug portion 3032 is inserted into the second through hole 1023 to prevent the free end portion (particularly, the protrusion 3033) of the second plug portion 3032 from coming out of contact with the ground on the circuit board.

The tab 3035 may be formed by cutting or stamping the second plug portion 3032 such that the base of the tab 3035 is attached to the second plug portion 3032 and the free end 3036 of the tab 3035 extends out of the plane of the second plug portion. Accordingly, the limiting step 1024 may be formed on an inner surface of the second through hole 1023 on a side corresponding to the free end 3036 of the tab 3035.

As best shown in fig. 1 and 5, the connector may include two conductive terminals 20 and two shields 30 surrounding the two conductive terminals. The connector may further comprise a connection 40 connecting the two shields.

As shown in fig. 5, the connector 40 may include a connection portion 401 connecting two shields 30 and a third ground leg 402 protruding from an edge of the connection portion 401, wherein the third ground leg is adapted to pass through a third penetration hole of the base plate 101 of the housing to contact a ground portion on a circuit board.
