Fig. 3 is a sectional view taken along line 3-3 in Fig. 2(A). Fig. 4 is a sectional view taken along line 4-4 of Fig. 2(A). In addition, in FIG. 4, both the shutter of a forward position and the shutter of a retracted position are shown in figure. Fig. 5 is a perspective view of the electrical connector of Fig. 1 showing a state in which the shutter is located at a retracted position.

The electrical connector 1 according to one embodiment of the present invention is, for example, an electrical connector provided on the bottom surface of a notebook type personal computer. The electrical connector 1 has a housing 2 , contacts 3 (signal contacts 31 and power contacts 32 ), a shutter 4 , a torsion spring 5 , and a cover 6 .

The case 2 is formed of a suitable resin such as liquid crystal polymer, and has a substantially rectangular parallelepiped shape. In the central portion of the case 2, an accommodation recess 22 defined by surrounding walls is formed. Inside the housing recess 22 , there are provided protrusions 23 extending upward from the bottom wall thereof while extending in two rows in the longitudinal direction of the casing 2 . Between the protrusion 23 and the walls 21 at both ends in the longitudinal direction of the housing 2 , a substantially square columnar post 24 is provided.

The contact 3 is composed of a signal contact 31 and a power contact 32 respectively formed by punching and bending a conductive metal plate such as copper alloy. The signal contact 31 has a contact portion 311 arranged along the protruding portion 23 of the housing 2 and a surface mount type substrate connection portion 312 extending to the outside of the housing 2 . The power contact 32 has a contact portion 321 embedded in a groove of the inner wall of the wall 21 at both ends of the case 2 in the longitudinal direction, a substrate connection portion 322 extending downward from the bottom surface of the case 2 , and a fixing part that is press-fitted and fixed by the wall 21 . Section 323. The contact portion 321 has a flat surface 324 facing the post 24 of the housing 2 . An inclined portion 325 is formed at the tip of the contact portion 321 . The inclined portion 325 is engaged with the corresponding inclined portion of the groove of the wall 21 of the housing 2 to prevent the contact portion 321 from tilting toward the column 24 .

The shutter 4 is formed of a suitable resin such as liquid crystal polymer, and has a thin plate shape. As shown in FIG. 4 , the shutter 4 is movable within the accommodation recess 22 between a raised forward position and a lowered retreated position. In the center portion of the shutter 4, openings 43 and 44 through which the protrusions 23 and the pillars 24 of the case 2 pass, respectively, are formed. An inclined portion 45 into which a guide post 86 of a mating connector 7 to be described later is formed at an end portion in the longitudinal direction of the shutter 4 .

The torsion spring 5 that urges the shutter 4 toward the mating connector 7 has a coil-shaped body portion 51 and a first arm 52 and a second arm 53 extending from the body portion 51 . The body portion 51 is housed in the housing portion 25 formed near both ends in the longitudinal direction of the case 2 . The first arm 52 is fixed in a groove adjoining the receptacle 25 of the housing 2 . The tip of the second arm 53 is engaged with the bottom surface of the shutter 4 .

The cover 6 is formed by punching and bending a conductive metal plate. The cover 6 covers most of the outer surface of the housing 2 , shielding the electrical connector 1 . The cover 6 is provided with a pressing portion 61 which presses the main body portion 51 of the spring 5 housed in the housing portion 25 of the case 2 from above to fix the spring 5 .

The posts 24 of the housing 2 are provided between the protrusions 23 that line up the contact portions 311 of the signal contacts 31 and the power contacts 32 . Therefore, by engaging with the opening 44 of the shutter 4 , while maintaining the guiding properties of the shutter 4 , the signal contacts 31 and the power contacts 32 are sufficiently separated to ensure a necessary space distance. In addition, by arranging the post 24 between the protruding portion 23 and the power contact 32 , it is possible to prevent a finger or the like from touching the power contact 32 as a charging portion.

Hereinafter, a mating partner connector (hereinafter referred to as a mating connector) 7 of the electrical connector 1 of FIG. 1 will be described. FIG. 6 is a perspective view of the mating connector 7 of the electrical connector 1 . FIG. 7 is (A) a plan view, (B) a front view, and (C) a right side view showing the mating connector 7 of FIG. 6 . Fig. 8 is a sectional view taken along line 8-8 of Fig. 7(A).

The mating connector 7 is, for example, an electrical connector provided on the docking station side. The mating connector 7 includes a housing 8 , contacts 9 (signal contacts 91 and power contacts 92 ), and a cover 95 .

The case 8 is formed of a suitable resin such as liquid crystal polymer, and has a substantially rectangular parallelepiped shape. A board mounting portion 82 protruding outward is provided at the lower end of the side surface of the housing 8 . In the central portion of the upper surface of the housing 8, recessed portions 83, 84 are formed to accommodate the protrusion 23 and the post 24 of the electrical connector 1, respectively.

The contact 9 is composed of a signal contact 91 and a power contact 92 respectively formed by punching and bending a conductive metal plate such as a copper alloy. The signal contact 91 has a contact portion 911 arranged along the concave portion 83 of the case 8 , and a surface mount type substrate connection portion 912 extending to the outside of the case 8 . The power contact 92 has a contact portion 921 exposed from both ends in the longitudinal direction of the case 8 , a substrate connection portion 922 extending downward from the bottom of the case 8 , and a fixing portion 923 press-fitted into the groove 85 of the case 8 . The contact portion 921 is an elastic contact portion whose tip portion is formed in an arc shape.

The housing 8 has a guide post 86 immediately above the contact portion 921 of the power contact 92 . A chamfer 861 is formed on the outer side of the guide post 86 . The chamfered portion 861 of the guide post 86 is guided by the inclined portion 45 of the shroud 4 of the electrical connector 1 . Therefore, even if the electrical connector 1 is located at a position that is difficult to see, such as the bottom surface of the personal computer, the electrical connector 1 and the mating connector 7 can be easily fitted.

The cover 95 is formed by punching and bending a conductive metal plate. The cover 95 covers most of the outer surface of the housing 8 , shielding the mating connector 7 .

Above, the electrical connector and the mating connector according to the embodiments of the present invention have been described in detail, but the present invention is not intended to be limited to these embodiments, and various modifications are possible. For example, in the above-described embodiments of the present invention, the shutter of the electrical connector is biased by a torsion spring, but it may also be biased by a type of spring other than the torsion spring.
