Description

[Detailed Description of the Invention] The present invention relates to a compact, non-insertion/extraction force type connector that does not require force to insert pin terminals of a mating connector.

Conventionally, a handle 1 is connected to a female connector 1 as shown in FIG.
7, the cam 18 of the handle 17 pushes and moves the drive plate 15, and the numerous through holes 16 provided in the drive plate 15 are moved.
The drive plate 15 presses and displaces the contacts 12 inserted into the housing 11 and inserted into the mating connector 2.
There is a connector that makes electrical connection by making contact with the pin terminal 21 of the connector.

There are two types of connectors: one is connected by inserting the pin terminal of the mating connector and then displacing the contacts, and the other is connecting by displacing the contacts, inserting the pin terminals of the mating connector, and releasing the displacement of the contacts. However, in either case, when inserting the pin terminal, there is no friction with the contact, and no force is required to insert the pin terminal, which is the so-called forceless insertion/extraction type.

However, this type of conventional connector has the disadvantage that since the operating handle is built in as a component of the connector, the external shape is large and the structure is complicated, which is particularly inconvenient for small-sized connectors.

The purpose of the present invention is to eliminate these drawbacks, to simplify the structure by eliminating the operating handle, and to enable the driving plate (referred to as the slider in the present invention) to be driven by applying an external force directly from outside the housing, making it compact and easy to handle. The purpose of the present invention is to provide a convenient connector with no insertion/extraction force.

In other words, the forceless insertion/extraction type connector according to the present invention has a plurality of rows of connectors planted in a housing, a plurality of sliders in which a number of comb-shaped walls that intersect with the contact rows are alternately combined and faced, and the slider Each comb-shaped wall holds one row of contacts in the contact row, and the sliders are housed in the housing so as to be slidable in the direction of the comb-shaped walls and biased away from each other, and are approached from the housing and the outside. The comb-shaped wall is provided with a recess that engages with the shoulder of the contact, so that the contact piece of the contact is displaced by the movement of the plurality of sliders.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In FIG. 2, the connector 3 is provided with two rows of press-fit holes 43 penetrating the bottom plate 41 (see FIG. 0) of the box-shaped housing 4, through which the terminal portions 57 of the contacts 5 protrude outside the housing 4. Then, press-fit the press-fitting part 51 and fix it.

The contact 5 has two contactors 52 and 53 that are press-fitted in a direction that opens perpendicularly to the direction in which the rows are arranged.

The housing 4 has a pair of opposite side walls 42 that are lower than the top surface of the housing 4, so that the cover 6 just fits there.

In the side wall 44 on the other pair of opposite sides, a large notch 45 is provided with one end in contact with the side wall 42 and the other end in the middle of the side wall 44 and facing diagonally between the opposite sides, forming a window with the cover 6. ing.

The sliders 7 a and 7 b are housed in the notch 45 .

The sliders 7 a , 7 b have a large number of comb-shaped walls 72 a , 72 b provided at right angles from the base portions 71 a , 71 b at equal intervals, and when the base portions 71 a , 71 b are housed in the notch 45 , the comb-shaped walls 72 a , 72b are arranged in a staggered manner, intersecting the rows of contacts 5, and one comb-shaped wall 72 in the direction in which the rows of contacts 5 are arranged.
a, 72b.

Figure a shows the state.

The comb-shaped walls 72 a and 72 b have recesses 73 a and 73
b is provided in a portion corresponding to the contact 5, but not provided on the side in contact with the side wall 42.

The sliders 7 a and 7 b are guided by the notches 45 and can freely slide on the bottom plate 41 in a direction intersecting the rows of contacts 5 .

The base portions 71 a, 71 b of the sliders 7 a, 7 b are provided with grooves 74 in the longitudinal direction of the base portions 71 a, 71 b, which are open on the sides contacting the bottom plate 41.
There is a protrusion 46 projecting from the bottom plate 41.

The grooves 74 and the grooves 46 engage to prevent the sliders 71a and 71b from being removed from the housing 4, and the grooves 46 and the grooves 74
A necessary number of return springs 8 are provided between the outer wall of the housing 4 and the outer wall of the housing 4, as shown in FIG.

Concave portions 73 of sliders 7 a and 7 b. a, 73
b are engaged with the shoulders 55 and 56 of the contact 5 shown in FIG. 3, and when force F is applied to the sliders 7 a and 7 b as shown in FIG. 2 d, for example by holding the connector 3 with a finger, the contact The contacts 52 and 53 of No. 5 open apart from each other against the elastic force.

When the force F is removed, the sliders 7a and 7b return due to the biasing force of the return spring 8, and the contacts 52 and 53 also return due to their own elastic force and come into contact with each other.

Contactor l-5 shown in FIG. 3 includes a terminal portion 57 extending from one end of a press-fitting portion 51, a contactor 52 extending from the other end, a connecting portion 54 extending perpendicularly from the contactor 52, and a connecting portion 54 extending at right angles thereto. There is a contact 52 and a contact 53 opposing it.

The protruding portions of the contacts 52 and 53 are bent into an arched shape and come into elastic contact with each other, and the tips are opened outward to facilitate insertion of the pin terminals of the mating connector.

The contacts 52 and 53 are provided with R55 and 56 which protrude from the plate surface at right angles to the axial direction of the contact 5 and extend in opposite directions.

As described above, the eyebrows 55, 56 engage with the recesses 73a, 73b of the sliders 7a, 7b.

The movement of the comb-shaped walls 72 a and 72 b of the sliders 7 a and 7 b and the movement of the contacts 52 and 53 of the contact 5 is as shown in FIG. 73a is engaged with the shoulder 55, and the shoulder 56 is engaged with the recess 73b of the comb-shaped wall 72b.

Furthermore, between the next comb-shaped wall 72 b and 72 a 2 , another type of contact 5 is used in which the scraps 55 and 56 of the contact 5 protrude to the side opposite to the figure, and the shoulders 55 and 56 are in the recess 73 .
a, 73b.

Looking at this with respect to the row of contacts 5 shown in FIG.
．． It can be seen whether the protrusion direction of 56 is different.

A hole 61 for receiving a pin terminal of a mating connector is provided in the cover 6 at a position corresponding to the contact 5.

Applying force F to the sliders 7a and 7b, the comb-shaped walls 72a and 72
Contact 5 engaged by recesses 73 a and 73 b of b
Press the shoulders 55 and 56 of the connector to open the contacts 52 and 53 apart from each other, and then insert the pin terminal of the mating connector through the hole 61 of the cover 6 and position it between the contacts 52 and 53. , except for the force F, the contacts 52 and 53 connect with the pin terminals of the mating connector due to their elastic force, and the slider 7
a, 7b return to their original position due to the biasing force of the door spring 8 until the side wall of the groove 74 comes into contact with the protrusion 46 of the housing 4.

In this way, the connector 3 can be electrically connected and coupled to a mating connector.

When detaching the mating connector, the operation described above can be reversed.

As is clear from the above explanation, according to the present invention, the operation handle built into the conventional non-insertion/extraction type connector can be removed, so the structure is simple, and it is small and can be handled by simply using the finger. A convenient connector with no insertion/extraction force can be obtained, and its practical advantages will be great if applied to IC socket connectors, etc.

In addition, in the embodiment, a structure with two rows of contacts was described, but there is no problem in slightly increasing the number of rows, and it is also possible to change the design of each part based on the technical idea of the present invention, for example, by fixing one side of the slider and only changing the other. Needless to say, this includes changing the recess of the comb-shaped wall, the position of the return spring, the position of the eyebrows of the contact, etc.
