Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a locking structure for a connector having a plug and a receptacle that can be fitted into and removed from each other.

[Conventional technology]

A conventional connector of this type is shown in FIG. The connector shown in Figure 6 is.

a receptacle 2 mounted and fixed on a printed circuit board;
The plug 3 is fitted into the receptacle 2. The receptacle 2 has a flat plate part 5 to which a plurality of conductive pin contacts 4 are fixed, and an anti-lock piece 6 extending upward from the edge of the flat plate part 5. The pin contact 4 penetrates the flat plate part 5 of the receptacle 2, and connects to the board]
It is inserted into the no through hole 9. Through hole 9
Here, the pin contact 4 and the wiring of the substrate 1 are connected. The opening pieces 6 of the receptacle 2 have dowels 11 near their tips that project in directions facing each other.

On the other hand, plug 3 has a socket contact (not shown)
is assembled to receive the pin contact 4 of the receptacle 2. The socket contact of the plug 3 is connected to a cable 15 such as a flat cable. Cable 15.

− Plug cover 1 fixed on the top surface of Ikuneko plug 3
It is held by 6. Dowels 13 are formed on both sides of the plug 3, respectively.

When the plug 3 is fitted into the receptacle 2, it is inserted between the lock pieces 6. At this time, the dowel 13 of the plug 3 engages with the lock piece 6' of the receptacle 2, thereby preventing the plug 3 from detaching from the receptacle 2.

When removing the plug 3 from the receptacle 2, as shown in FIG. Release the lock state with 11. In this state, as shown in FIG. 8, when the plug 3 and the plug cover 16 are pulled upward, the plug is removed from the receptacle 2.

[Problem that the invention seeks to solve]

However, when releasing the fitting between the receptacle 2 and the plug 3, the lock piece 6 must be bent outward and the plug 3t must be pulled out from the receptacle 2 in this state, making it impossible to operate with one hand. Poor operability. Also.

There is a problem in that a special tool is required to bend the lock piece 6 in a narrow space.

Further, the lock piece 6f: If handled roughly, the lock piece 6 may be damaged due to excessive deformation.

Therefore, it is an object of the present invention to provide a locking structure for a connector that allows the locking mechanism to be easily removed by one-handed operation even in a narrow space.

[Means and effects for solving the problem] According to the present invention, in the locking structure between a plug and a receptacle that can be fitted into and separated from each other, a dowel provided on the side surface of the plug and a dowel provided on the receptacle are provided. and a flexible locking piece that engages with the dowel to prevent separation between the plug and the receptacle, and a plug cover that is slidably combined with the plug in the mating/uncoupling direction, plug cover.

In the fitted state of the above plug and receptacle.

It has a lock piece operation part interposed between the side surface of the plug and the lock piece, and when the lock piece operation part is slid in the detachment direction, the lock piece is bent and the lock piece is connected to the lock piece. A locking structure for a connector is obtained, which is characterized in that it engages with the dowel while disengaging from the dowel.

〔Example〕

FIGS. 1 and 2 show an embodiment of a locking structure of a connector according to the present invention. The connector.

It has a receptacle n mounted and fixed on a wiring board 21 such as a printed circuit board, and a plug n that can be fitted into or removed from the receptacle n.

Receptacle n has a plurality of conductive pin contacts 2
It has a flat plate part 25 to which 4 is fixed.

The pin contact hole penetrates through the flat plate portion 25f and connects to the substrate 21.
is inserted into the through hole 4 of the circuit board 21, and the wiring and soldering of the board 21 are electrically connected by, etc.

A side wall 31 surrounding the bottle contact 24 is integrally provided on the flat plate portion 5 of the receptacle ρ. The side wall 31 has a pair of lock pieces 32''fr: facing each other.
It is separated from other parts of. The pair of lock pieces 32 are formed so as to be able to bend away from each other. Also.

The lock piece 32 also covers the top surface of other parts of the side wall 31.

It extends further upwards. The pair of lock pieces 32 is.

First dowels 35f are provided on the upper portions of the surfaces facing each other and project in a direction toward each other.

The first dowel 35 has inclined surfaces 40 at its upper and lower ends, respectively.
．． 41'i. Furthermore, a shoulder 43 is formed in the notch 42 at the center of the lower end of the first dowel 35 and is perpendicular to the plate surface of the lock piece 32.

The plug wing has an electrically conductive socket contact (not shown) therein for electrical connection with the bottle contact 24. A cable 51 such as a flat cable extending above the plug O is connected to the socket contact. A plug cover 52 is combined with the flag B, which is slidable in the direction of engagement and disengagement. The plug cover 52 is divided into two parts,
The cables 51 are combined with each other so as to surround each other with a gap, and are fixed to each other with screws 53. The plug cover 52 is.

It has a pair of frame portions 55 facing the side surfaces of the plug B.

The frame portion 55 constitutes a lock piece operating portion. These frame portions 55 are fitted into recesses 56 formed on the pair of side surfaces of plug A.

A second dowel 57 is located inside the frame portion 55 and is integrally formed with the side surface of the plug swamp. This second dowel 57
The width of the notch 42 forming the shoulder 43 of the lock piece 32 is also smaller.

The plug n and the plug cover 52 are integrated,
As shown in FIG. 3, it is fitted inside the side wall 31 of the receptacle n. This insertion is allowed because the inclined surface 40 is pushed by the frame portion 55 and the lock piece 32 is bent outward. At this time, the pin contact 24 is received in the socket contact of the plug B, and an electrical connection is established. Further, the second dowel 57 is inserted into the notch 42 of the first dowel. As a result, as shown in FIG. 3, the second dowel 57 does not engage with the shoulder 43, thereby preventing the plug device from coming off, ie, in a locked state.

When separating the locked plug B and receptacle N, lift the plug cover 52f upward. Then, only the plug cover 52 moves upward, leaving the cable 5 and the plug holder in the same state. At this time, the lower part of the frame 5 of the plug cover 52 comes into contact with the inclined surface 41 of the lower end of the first dowel of the lock piece 32. Further, the frame group of the plug cover 52 rises while pushing the inclined surface 41 of the first dowel outward, thereby bending the lock piece 32 outward as shown in FIG. As a result, the engagement between the second dowel 57 of the plug B and the lock piece 32 of the receptacle B after the first dowel is released. Further, when the plug cover 52 is pulled up, the frame portion 55 engages with the second dowel 57 and pulls up the plug 23. Therefore, as shown in FIG.

Plug n separates from receptacle n. in this way,
Just pull up the plug cover 52.

Plug n can be removed from receptacle n. It goes without saying that in the fitted state, even if tension is applied to the cable, the second dowel 57 is engaged with the shoulder 43, so the plug n will not come off from the receptacle n.

〔Effect of the invention〕

As described above using the embodiments, according to the present invention, connectors can be fitted or removed with a one-touch operation. Therefore, it can be easily operated even in a narrow installation space, and no fingers or tools are required. In addition, excessive deformation of the lock can be prevented, eliminating damage to the connector.
