Description

  The present invention relates to a floating electrical connector in a board-to-board connector, for example.

Conventionally, a floating type electrical connector is one of male and female connectors so that when a board of printed circuit boards is electrically connected to each other via a connector, a mating operation can be smoothly performed by absorbing molding errors and assembly errors. Is provided with a floating housing. The configuration includes, for example, a fixed housing fixed to the circuit board, a floating housing parallel to the surface of the circuit board and movable with respect to the fixed housing, and a contact ( It is known that the floating housing is movable in a flexible part formed in the middle part of the contact (see Patent Document 1).
JP-A-10-55856

  However, in the conventional floating type electrical connector, since the floating housing is supported only by the contactor, for example, when the floating type electrical connector is mounted on the circuit board, a suction device is attached to the upper surface of the floating housing by a mounting device. , The floating housing is pressed down and displaced due to the impact, or a part of the floating housing collides with the fixed housing due to vibration during transportation of the connector, and a rattling noise is generated. The floating electrical connector according to the present invention has been proposed in order to solve such problems.

  The gist for solving the above-mentioned problems of the floating type electrical connector according to the present invention is to achieve a floating housing supported in a floating state by a fixed housing fixed to a printed circuit board and a contact through a contact. In the floating type electrical connector constituted by the above, the lower surface of the floating housing is supported on the fixed housing so that the floating housing does not move downward in the insertion direction when the connector fitting direction is the vertical direction. The position restricting member is provided.

The position regulating member is a support member having a support surface formed by bending and projecting a part of each hold down of the hold down provided on the left and right end sides of the fixed housing in a substantially horizontal direction;
An elastic member for absorbing vibration is attached to the support surface of the position regulating member;
Is included.

  According to the floating type electrical connector of the present invention, when the printed circuit boards are fitted with the floating type electrical connector and the mating electrical connector, even if the floating housing of the floating type electrical connector is pressed in the insertion direction, The position restricting member prevents movement in the insertion direction. When this floating electrical connector is mounted on a printed circuit board, even if it is pushed in the insertion direction by a suction device that sucks the connector, the movement is similarly prevented.

Further, by forming the position regulating member by a part of the hold down used for fixing to the printed circuit board, the object can be easily achieved without increasing the number of separate parts.
Furthermore, during the transportation of the floating electrical connector, in the conventional example, a part of the floating housing collides with a part of the fixed housing due to vibration, and noise is generated. Is provided, the vibration is absorbed and the generation of the abnormal noise is prevented.

  As shown in FIGS. 1 to 3, the floating electrical connector 1 according to the present invention floats on the fixed housing 2 via a contact 3 and a fixed housing 2 which is surface-mounted on the printed circuit board side and fixed. And a floating housing 4 to be supported.

  The fixed housing 2 is a rectangular synthetic resin housing that is elongated in the left-right direction. A rectangular space is formed at the center, and a plurality of press-fitting holes 2a for the contacts 3 are formed on the lower surfaces of the front and rear frames. It is attached. In addition, fitting holes 2b for press-fitting and fixing the holddown 5 from below are provided at the left and right ends. Further, four support legs 2c are provided for surface mounting on the printed circuit board 6 shown in FIG.

  The floating housing 4 is made of a synthetic resin, and as shown in FIG. 3, a rectangular protrusion-like projection 4 a is formed in the left and right directions from the flat plate body, and there is a slit-shaped storage for the contact 3. A large number of parts 4b are provided side by side in the left-right direction at two places on the front and rear. The protrusion 4a is accommodated in the space of the fixed housing 2, and a part of each contact 3 is attached to form a contact portion with the mating connector.

  As shown in FIGS. 3 to 4, the contact 3 is provided with fitting portions 3b and 3c with a housing via a large curved portion 3a. Further, in the contact 3, the fitting portion 3b press-fitted into the housing portion 4b of the floating housing 4 is slidably contacted with the contact 7a of the female connector 7 mounted on the printed board 8 shown in FIG. A contact piece 3d is formed in contact therewith.

  As shown in FIGS. 3 to 4, the contacts 3 are arranged to face each other, and a large number of the contacts 3 are provided side by side to support the floating housing 4 fitted with the fitting portion 3c. By providing the curved portion 3a of the contact 3, the floating housing 4 is supported so that it can move up and down, left and right and up and down, and its position can be adjusted when fitted.

  As shown in FIGS. 2 to 3, the hold-down 5 press-fitted into the fitting hole 2b of the fixed housing 2 is bent in the fitting portion 5c and a direction (horizontal direction) orthogonal to the fitting portion 5c. A fixed portion 5a soldered to the printed circuit board 6 and a position restricting portion 5b that is bent and protruded in the same orthogonal direction (horizontal direction) are formed.

  The position restricting portion 5b is a downward direction that is an insertion direction when the female connector 7 is fitted to the floating electrical connector 1 or when the connector fitting direction is the vertical direction in a vibration state during transportation. This is a position regulating member formed with a support surface (upper surface) for supporting the lower surface of the floating housing 4 so that the floating housing 4 does not move.

  Furthermore, an elastic member for absorbing vibration, for example, a synthetic resin thin plate such as an elastic tape or a rubber plate, is attached to the support surface (upper surface) of the position restricting portion 5b. Thereby, the impact on the contact surface between the floating housing 4 and the position restricting portion 5b is alleviated, and the quietness is improved when the floating electrical connector 1 is transported.

  According to the floating type electrical connector 1 formed in this way, as shown in FIG. 4, the floating type electrical connector 1 is surface-mounted on the printed circuit board 6 by soldering, and the hold down 5a is soldered. The On the other hand, the female connector 7 is also surface-mounted on the printed circuit board 8.

  When the connector 1 and the female connector 7 are fitted, the floating housing 4 freely moves in the front-rear and left-right directions, absorbs assembly errors and the like, and is aligned and smoothly fitted. At the time of this fitting, the downward movement of the floating housing 4 is prevented by the support surface of the position restricting portion 5b of the hold down 5, and the curved portion 3a of the contact 3 is protected.

  Therefore, there is no possibility that the contact 3 is deformed by the downward movement of the floating housing 4 due to the fitting between the connectors mounted on the printed circuit board. Then, the contact piece 3d of the contact 3 and the contact 7a of the female connector 7 are reliably fitted, and the contact state is stabilized.

It is the perspective view seen from diagonally upward of the floating type electrical connector 1 which concerns on this invention. It is the perspective view seen from diagonally lower of the floating type electrical connector of the same invention. FIG. 3 is an exploded perspective view of the floating electrical connector 1.
