Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an anti-static connector (hereinafter referred to simply as a connector) that connects grounding members provided on a plug and a socket to each other when the plug and socket are connected. .

2. Description of the Related Art In general, as the above-mentioned connector sockets, there are known anti-static type sockets in which static electricity from the human body or the like falls to the ground before reaching the signal terminal.

Problems to be Solved by the Invention The metal piece for static electricity prevention used in conventional sockets is formed separately from the contact piece for ground connection, which increases the number of parts and increases costs. There was a drawback.

The present invention was developed in view of the above circumstances, and the purpose is to provide a connector that uses a common metal piece for static electricity countermeasures and a contact piece for ground connection, thereby reducing the number of parts and reducing costs. There is.

Means for Solving the Problems In the connector according to the present invention, the grounding member on the socket side is formed into a substantially U-shaped integral molding that is fitted across the plug connection surface of the socket body, and one end of the grounding member is fitted over the plug connection surface of the socket body. An elastic inner lead piece is connected to the outer lead piece protruding from the outer lead piece, and the grounding member on the plug side is connected to the other end side by sliding contact.

Function: The external lead piece is connected to the printed circuit board or lead wire, and the grounding member on the plug side is grounded via the grounding member on the socket side. Furthermore, the connecting piece that connects the internal lead piece and the external lead piece by straddling the plug connection surface of the grounding member of the socket is a static electricity countermeasure that is particularly easy to touch when a plug is not connected to the socket. exposed outside the socket as a piece of metal.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

1 is an exploded perspective view of a connector according to an embodiment of the present invention, FIG. 2 is a front cross-sectional view of the assembled state shown in FIG. 1, and FIG. 3 is a cross-sectional view taken along the line -- in FIG. 2.

In these figures, reference numeral 1 denotes a socket, and the socket body 10 is made of an insulating material and has a substantially rectangular parallelepiped shape.
1, a rectangular frame-shaped annular groove 103 is formed inside the socket body 101 along the outer wall 102, and the upper surface of the rectangle surrounded by the annular groove 103 is a plug connection surface 104. A plurality of terminal holes 105 passing through the plug connection surface 104 in the vertical direction are formed in two rows, and each terminal hole 105
The socket terminal 2 is fitted and held from below so that the external lead piece 201 protrudes from the bottom of the socket. Thus, the socket body 101 is provided with positioning holes 106 extending vertically through both longitudinal ends thereof.

Reference numeral 3 designates a grounding member on the socket side, and an internal lead piece 301 is inserted into the annular groove 103 at a position near one end of the plug connection surface 104 of the socket body 101.
, the socket terminals 2 are inserted into the annular groove 103 at a position near the other end and protrude from the bottom of the socket.
An external lead piece 302 is connected to a printed circuit board or a lead wire (not shown) together with the external lead piece 201.
and a connecting piece 30 that spans over the plug connection surface 104 and connects both the lead pieces 301 and 302.
It is an almost U-shaped integral molded product consisting of 3. Thus, the connecting piece 303 is fitted into a positioning groove 107 formed on the plug connecting surface 104 between the rows of terminal holes 105, and the inner lead piece 301 is in a free state as shown in FIG. The outer lead piece 302 is in an inclined state with its lower end elastically displaced to the left, and the external lead piece 302 is press-fitted and fixed into the through hole at the bottom of the socket by a locking piece 304.

Reference numeral 4 denotes a plug, which is made of an insulating material and includes a plug body 401 having a shape that matches the socket body 101 in plan view, and at both longitudinal ends of this plug body 401, holes are provided for each positioning hole 106 of the socket body 101. The upper ends of matching positioning pins 402 are caulked and fixed. Further, a plurality of plug terminals 403 whose lower ends are inserted into the respective terminal holes 105, that is, the upper bifurcated portion of each socket body 101 are press-fitted into the plug body 401, and the upper ends of each plug terminal 403 are inserted into the plug body 401. It protrudes from the top. 5 is a grounding member on the side of the plug 4, which includes the lower part of the group of plug terminals 403,
It is formed into an annular body that fits into the annular groove 103 of the socket body 101, and is fixed to the plug body 401 by insert molding. An external grounding piece 501 that projects from the top surface of the plug body 401 is integrally formed at the upper end of the grounding member 5 .

In the above configuration, as shown in FIG. 4, the grounding member 5 is installed in the socket main body 101 from the direction of arrow A, spanning the plug connection surface 104, but in this state, that is, the state in which the plug 4 is not connected to the socket 1. Here, the connecting piece 303 of the grounding member 3 on the side of the socket 1 is exposed on the upper surface of the socket as a metal piece for anti-static electricity that is particularly easy to touch. That is, a finger charged with static electricity may touch the plug connection surface 10 of the socket 1.
4, the static electricity falls on the connection piece 303 of the grounding member 3 before reaching the socket terminal 2, and is grounded from the external lead piece 302 through a printed circuit board (not shown) to which this lead piece 302 is connected.

Furthermore, in the state shown in FIG. 4, when each positioning pin 402 of the plug 4 is inserted into each positioning hole 106 of the socket 1 in the direction of arrow A, the lower part of each plug terminal 403 is connected to the upper part of a predetermined socket terminal 2 ( (see Figure 3) and the plug 4
The side grounding member 5 is fitted into the annular groove 103 of the socket 1. At this time, a part of the lower end of the grounding member 5 on the plug 4 side is connected by sliding contact with the internal lead piece 301 of the grounding member 3 on the socket 1 side (see Fig. 2), and the elastic return force of the internal lead piece 301 (the 2, the connection state between both ground members 3 and 5 is maintained by the force in the left direction.

Although the ground member 3 on the socket 1 side described in the above embodiment is a linear body with a rectangular cross section, it may be a linear body with a round cross section. Furthermore, in order to make the static electricity countermeasure more complete, for example, as shown in FIG. 5, a plurality of strips 305 are formed from the connecting piece 303 of the grounding member 3, or as shown in FIG.
The connecting piece 303 can be plate-shaped. When the strips 305 shown in FIG. 5 are provided, the dimensions between the strips 305 are set so that the plug terminal 403 can be inserted therethrough, and when the strips 305 are provided in the plate shape shown in FIG. 6, the plug terminal insertion holes 306 is formed.

Further, in each of the above embodiments, the grounding member 3 on the socket 1 side was configured to be fixed to the socket body 101 with the external lead piece 302, but the connecting piece 30
It may be fixed at 3.

Effects of the Invention As explained above, according to the connector according to the present invention, the grounding member on the socket side is formed into a substantially U-shaped integral molding that is fitted across the plug connection surface of the socket body, and one end thereof is The external lead piece that protrudes from the bottom of the socket has an elastic internal lead piece that slides into contact with the grounding member on the plug side at the other end, which means that there is a metal piece for static electricity countermeasures and a contact piece for grounding. Since these are standardized, it is possible to reduce the number of parts and reduce costs.
