Abstract

A USB receptacle connector has a housing and a shell enclosing the housing. The housing has a mating face which forms a recess for receiving a counterpart USB plug connector, and a tongue in the recess having a first surface and an opposite second surface both parallel to a width direction of the housing. A first group of contact terminals each has a contact end disposed on the first surface. A second set of contact terminals each has a contact end disposed on the second. Each of the first and second sets of contact terminals has a mounting end which extends out of the housing and disposed on a mounting face which is perpendicular to the width direction of the housing. Such a connector is suitable for mounting in a very tight space which may be even narrower than the width dimension of the shell.

Description

SIDE MOUNTABLE USB RECEPTACLE CONNECTOR
TECHNICAL FIELD
The present invention relates to an electrical connector. In particular, it relates to a Universal Serial Bus (USB) receptacle connector.
BACKGROUND
Universal Serial Bus (USB) receptacle connectors are used in electronic systems such as computers or audio-visual devices to provide an interface to communicate with peripheral devices. In certain applications or electronic systems, the space available for mounting a USB receptacle connector is very tight, which may even be narrower than the width dimension of a standard USB receptacle connector. To provide USB interface connections at such a tight space, substantial changes to the physical structures and dimensions of the present standard USB receptacle connector becomes necessary. However, such changes can make the connector no longer able to mate with counterpart standard plug connectors and in turn, the plug connectors will have to be modified too, which may result in inconvenience to the usage of these electronic devices.
In addition, such dimensional changes may also degrade the electrical performances of the connector.
It is therefore desirable to provide a USB receptacle connector suitable for such tight spaces of electronic devices without the need to modify the counterpart plug connectors. SUMMARY OF INVENTION
Disclosed therein are USB receptacle connectors according to embodiments of the present invention, which are structured for being mounted on a PCB with very tight space limitations.
In one embodiment, a USB receptacle connector includes a housing and a shell enclosing the housing. The housing has a mating face which forms a recess for receiving a counterpart USB plug connector, and a tongue in the recess having a first surface and an opposite second surface both oriented parallel to a width direction of the housing. A first set of contact terminals each has a contact end disposed at the first surface of the tongue. A second set of contact terminals each has a contact end disposed at the second surface of the tongue. Each of the first and second sets of contact terminals has a mounting end which extends out of the housing and disposed on a mounting face which is perpendicular to the width direction of the housing. Such a connector is suitable for mounting in a very tight space which may be even narrower than the width dimension of the shell. In the meantime the overall structure of the connector is maintained to meet industrial standards and compatibility and the electrical performances are not compromised.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in Figs. 1 to 5, a USB type B receptacle connector 10 according to one embodiment of the present invention has a housing 20, a shell 30 partially enclosing housing 20, and four contact terminals 41 , 42, 43 and 44 disposed in housing 20. Housing 20 has a mating face 28 which forms a recess 21 for receiving a counterpart USB plug connector (not shown), and a support member in the form of a tongue 22 disposed in recess 21. Recess 21 is generally a rectangular shape with a recess width 21a and recess height 21b which is slightly smaller than width 21a according to USB type B receptacle standard. For the purpose of illustration, a direction parallel to width 21a is referred to in the context as width direction 10a of connector 10, and a direction parallel to height direction 21b is referred to as height direction 10b of connector 10. Following the dimensional relationship of recess width 21a and recess height 21 b, connector height 14 is also slightly smaller than connector width 12.
Each of contact terminals 41 and 42 respectively has a contact end 41 a and 42a disposed on the top or first surface 22a of tongue 22. Contact terminals
43 and 44 each has a respective contact end 43a and 44a disposed on the bottom or second surface 22b of tongue 22. Contact terminals 41 , 42, 43, and 44 each has a retention portion 41c, 42c, 43c and 44c at middle part thereof, to fix each contact terminal to housing 20. Contact ends 41a and 42a are aligned along a first horizontal row 46a, and contact ends 43a and 44a are aligned along a second horizontal row 48a, as shown in Fig. 5, according to USB type B receptacle standard. This configuration provides connector 10 with standard mating face with counterpart USB plugs.
To mount connector 10 onto a printed circuit board (PCB) which has a very limited layout or tight mounting space, contact terminals 41 , 42, 43 and 44 are extended in a backward direction 68 away from mating fact 28 (Fig. 4), and further extended from retention portions 41c, 42c, 43c and 44c along a side direction 66 toward a side surface 26 of housing 20, and terminated at respective mounting ends 41 b, 42b, 43b and 44b disposed outside side surface 26. Mounting legs 34 of shell 30 and posts 24 of housing 20 are also extended from the same side surface 26, for positioning and fixing the connector 10 to PCB 50. This arrangement makes side surface 26 a mounting face for mounting connector 10 to PCB 50, as shown in Figs 6 and 7.
Referring back to Figs. 4 and 5, contact end 41a of contact terminal 41 and contact end 42a are disposed in one horizontal row 46a and in a same horizontal plane which is perpendicular to both mating face 28 and mounting face 26. However, retention portions 41 c and 42c of contact terminals 41 and 42 are disposed in different two horizontal planes 46b and 47b which are perpendicular to both mating face 28 and mounting face 26. This structure can be formed by deforming one or both the retention portion 41c of first contact terminal 41 and retention portion 42c of second contact terminal 42 away from each other. According to one embodiment, the contact end and the retaining portion of one of the first set of contact terminals are disposed in a same horizontal plane which is coplanar with the top or first surface 22a of tongue 22, and the contact end and the retaining portion of the other one of the first set of contact terminals are disposed in different horizontal planes. According to another embodiment, the contact end and the retaining portion of both contact terminals of the first set are disposed in different horizontal planes. Retention portions 43c and 44c of third and fourth contact terminals 43 and 44 can be arranged in a similar manner.
Extending from respective retention portions 41c, 42c, 43c and 44c along side direction 66, there are disposed, in respective same horizontal plane 46b,
47b, 48b and 49b, mounting ends 41 b, 42b, 43b and 44b of contact terminals 41 , 42, 43, and 44. In the present embodiment, mounting ends 41b, 42b, 43b and 44b are arranged along a single alignment row 45 which is perpendicular to first surface 22a of tongue 22.
As shown in Fig. 6, posts 24 and legs 34 are also extended along the same direction as the mounting ends of the contact terminals, for inserting into respective through holes 52 and 53 of PCB 50.
As shown in Fig. 7, by configuring side surface 26 as a mounting face of connector 10, the height 14 occupies the width limits of PCB 50. As such, the available mounting space 55 of PCB, which maybe even smaller than the width 12 of connector 10, can well accommodate connector 10 with a standard width 12. Modification for counterpart plug connectors is not required.
