Detailed Description

A connector assembly according to an embodiment of the present utility model will be described below with reference to the accompanying drawings. In the drawings, the same elements or elements having the same function are denoted by the same reference numerals. The figures are not drawn to scale. It should be noted that, hereinafter, unless otherwise indicated, the term "contact" generally refers to a signal contact.

First embodiment

Fig. 1 is a perspective view of a connector assembly according to a first embodiment of the present utility model in a fitted state. The connector assembly is generally indicated by reference numeral 10. The connector assembly 10 includes a floating connector 12 and a mating connector 14. Fig. 2 is a perspective view of the connector assembly 10 in an unengaged state.

The floating connector 12 is embodied as a receptacle connector and the mating connector 14 is embodied as a plug connector.

Fig. 3 is an exploded perspective view of the floating connector 12 according to the first embodiment of the present utility model. Fig. 4 is a cross-sectional side view of the floating connector 12 according to the first embodiment of the present utility model. The constituent elements of the floating connector 12 according to the first embodiment of the present utility model will be schematically described with reference to fig. 3 and 4.

As shown in fig. 3 and 4, the floating connector 12 includes a first housing 20 as a fixed housing, a second housing 30 as a movable housing, two contact assemblies CA, a plurality of power contacts 60, a conductive housing 32, and two ground fittings 70.

The second housing 30 includes a fitting portion 34 that is fitted to the mating connector 14 in the first direction (Z-axis direction). The second housing 30 is mounted to the first housing 20 in a movable manner on a plane (XY plane) perpendicular to the first direction. The conductive housing 32 is fitted on the second housing 30 so as to substantially cover the outer peripheral surface of the second housing 30.

In the present embodiment, one contact assembly CA includes 120 contacts 40, and the floating connector 12 including two contact assemblies CA includes 240 contacts 40 in total. The floating connector 12 has 16 power contacts 60. The contacts 40 and the power contacts 60 are made of a conductive material, such as copper or a copper alloy. However, the present utility model is not limited thereto, and the number of contacts or power contacts may be increased or decreased as necessary.

With reference to fig. 5, 6 and 7, the contact assembly CA and its modification will be further described.

Fig. 5 is a perspective view of the contact assembly CA according to the first embodiment of the present utility model. Fig. 6 is a front view of the contact assembly CA according to the first embodiment of the present utility model. The contact assembly CA includes a resin insulator member 50 and a plurality of contacts 40. The contacts 40 are aligned at a predetermined pitch in a second direction (Y-axis direction) perpendicular to the first direction. The insulator member 50 extends in the second direction. The insulator member 50 and the contacts 40 are integrally formed by insert molding (insert molding) such that the insulator member 50 holds the contacts 40 at a predetermined pitch and covers a portion of each contact 40, particularly a portion of a spring portion (to be described later) of the contact 40.

Fig. 7 is a front view of a contact assembly CA' according to a variation of the present utility model. The difference from the contact assembly CA is that the contact assembly CA ' of the modification includes the insulator member 50' and 40 contacts, and the size of the contact assembly CA ' in the second direction (Y-axis direction) is about 1/3 of the contact assembly CA. Shrinkage, deformation or warpage of the insulator members of the contact assemblies can cause problems in that the spacing of the contacts of the contact assemblies does not match the prescribed contact spacing of the floating connector. To alleviate the above problem, the contact assembly CA is divided into 3 contact assemblies CA'. A plurality of contact assemblies CA' can be obtained by dividing the contact assemblies CA. The contact assembly CA' may also be directly formed by insert molding.

Fig. 8 is a perspective view of the contact 40. The contact 40 includes: a fixing portion 41, a first holding portion 42, a spring portion 43, a second holding portion 44, and a contact portion 45. The first holding portion 42 continues from the fixing portion 41, the spring portion 43 connects the first holding portion 42 and the second holding portion 44, and the contact portion 45 continues from the second holding portion 44. The fixing portion 41 is to be fixed to the printed circuit board by soldering. The first holding portion 42 is press-fitted to the first housing 20 to be held by the first housing 20. The second holding portion 44 is press-fitted to the second housing 30 and held by the second housing 30.

The spring portion 43 includes a first bending portion 431, a first extending portion 432, a second bending portion 433, and a second extending portion 434. The first extension portion 432 is connected to the first holding portion 42 by the first bending portion 431. The second extension 434 is connected to the first extension 432 by a second bend 433. The bending direction of the first bending portion 431 is different from the bending direction of the second bending portion 433.

In order to suppress signal reflection or impedance variation on the contact 40, an angle θ1 between the first extension 432 and the virtual extension line L1 of the first holding portion 42 is set to 45 degrees or less, an angle θ2 between the second extension 434 and the virtual extension line L2 of the first extension 432 is set to 45 degrees or less, and the second extension 434 is in line with the second holding portion 44.

The portion of the contact 40 that is covered by the insulator member 50 is a portion of the second extension 434 that is adjacent to the second retention portion 44. In order to increase the adhesion of the insulator member 50 to the contact 40, a necked-down portion is formed in the portion of the contact 40 covered by the insulator member 50.

The insulator member 50 may provide a point of action for the mounting fixture during press-fitting of the contact 40 to the second housing 30. In contrast to conventional floating connectors, because there is no need to have the mounting jig directly touch the second holding portion of the contact, there is no need to bend the second extension portion with respect to the second holding portion. Thus, the number of bending times of the contact is reduced, so that it is possible to use a contact with a simpler geometric shape. This is very advantageous for the impedance characteristics of the contact.

On the other hand, the impedance characteristics of the contact are also affected by the dielectric constant of the surrounding dielectric. Thus, it is also possible to adjust the impedance characteristics of the contact 40 by wrapping the contact 40 with the insulator member 50.

Fig. 9 is a perspective view of the power contact 60. To transmit greater current, the power contact 60 is made to have a wider width than the contact 40. The power contact 60 has a fixing portion 61, a first holding portion 62, a spring portion 63, a second holding portion 64, and a contact portion 65.

The first holding portion 62 continues from the fixing portion 61. The spring portion 63 connects the first holding portion 62 and the second holding portion 64. The contact portion 65 continues from the second holding portion 64. The fixing portion 61 is to be fixed to the printed circuit board by soldering. The first holding portion 62 is press-fitted to the first housing 20 to be held by the first housing 20. The second holding portion 64 is press-fitted to the second housing 30 and held by the second housing 30. In order to facilitate elastic deformation of the power supply contact 60, an elongated slit 631 and an elongated slit 651 are formed in the spring portion 63 and the contact portion 65, respectively.

Fig. 10 is a perspective view of the second housing 30 equipped with the conductive shell 32. Fig. 11 is an exploded perspective view showing only the conductive housing 32 and the second case 30.

The second housing 30 has a fitting portion 34 to be fitted with a mating connector. The contact portion 45 of the contact 40 and the contact portion 65 of the power contact 60 are located in the fitting portion 34. The second housing 30 includes a plurality of first holding holes 301 and a plurality of second holding holes 302. The conductive housing 32 has a body portion 320, a plurality of first holding portions 321 formed at the lower edge of the body portion 320, two side contact portions 323, and a second holding portion 322 formed at the two side contact portions 323. The two side contact portions 323 are located at both ends of the body portion 320, respectively, and are parallel to a plane (XY plane) perpendicular to the first direction. The first retaining portion 321 is inserted into the first retaining hole 301 with an interference fit, and the second retaining portion 322 is inserted into the second retaining hole 302 with an interference fit, thereby assembling the conductive housing 32 to the second case 30.

Fig. 12 is a partially enlarged perspective view of the floating connector 12 according to the first embodiment of the present utility model.

The ground fitting 70 is fitted to an end of the first housing 20 to prevent the second housing 30 from moving in the first direction and to prevent the second housing 30 from being separated from the first housing 20. In this way, the second housing 30 is restricted to move relative to the first housing 20 only in a plane (XY plane) perpendicular to the first direction (Z axis direction).

Fig. 13 is a perspective view of the ground fitting 70. The ground fitting 70 has a body portion 72 and two fixing leg portions 74 formed at both ends of the body portion 72, respectively. The body portion 72 is formed with a contact arm 721 for contacting the contact portion 323 of the conductive housing 32. Specifically, the end of the contact arm 721 is formed with a biasing portion 722 that is biased toward the contact portion 323 to promote contact between the contact arm 721 and the contact portion 323. The ends of the contact arms 721 may be torn by die cutting such that a portion of the ends of the contact arms 721 are bent or offset toward the side contact 323 relative to the other portions. The edge 723 of the offset portion 722 may be utilized as a scraping means for scraping oxide formed on the contact portion 323 or foreign matter or dust deposited on the contact portion 323 when the second casing 30 moves relative to the first casing 20. With such scraping means, poor contact between the ground fitting and the conductive housing can be prevented.

Each of the fixing leg portions 74 has a holding portion 741 and a fixing portion 742. The ground fitting 70 is assembled to the first housing 20 by inserting the holding portion 741 into the first housing 20 in an interference fit. The fixing portion 742 will be fixed to the printed circuit board by soldering. In this way, the ground fitting 70 is grounded through the two fixing legs 74. Accordingly, the conductive housing 32 is grounded through the grounding fitting 70, establishing an electrostatic discharge path P1 of the conductive housing 32, as shown in fig. 12.

The contact portion 323 of the conductive housing 32 is configured to have a sufficient area such that the contact arm 721 of the ground fitting 70 is still in contact with the contact portion 323 of the conductive housing 32 when the second housing 30 is moved to the extreme position in each direction. Thereby, it is ensured that the electrical connection between the conductive housing 32 and the ground fitting 70 is maintained during the floating of the second housing 30 relative to the first housing 20.

In this way, the second housing 30 is restricted to move relative to the first housing 20 only in a plane perpendicular to the first direction.

Details of the ground fitting 70 are shown in fig. 26 and 27, where fig. 26 is a perspective view of the ground fitting 70 and fig. 27 is another perspective view of the ground fitting 70.

As shown in fig. 26 and 27, the grounding accessory 70 includes a main body 72, two fixing leg portions 74, and one grounding leg portion 76.
