Description

  The present invention relates to a connector, and more particularly to a connector in which a contact is press-fitted and held in a press-fitting hole of a housing.

2. Description of the Related Art Conventionally, a connector in which a flat plate or prismatic contact is press-fitted and held in a press-fitting hole formed in an electrically insulating housing is widely known.
For example, in the connector disclosed in Patent Document 1, as shown in FIG. 20A, the contact 1 includes a flat contact body 2 extending in the press-fitting direction, and both sides of the contact body 2. And a protrusion 3 protruding in the plate width direction. On the other hand, the housing 4 has a press-fitting hole 5 having a rectangular cross section for inserting the contact 1, and a protrusion holding part 6 that accommodates and holds the protrusion 3 of the contact 1 inside the press-fitting hole 5.

The contact 1 is held in the housing 4 by inserting the contact 1 into the press-fitting hole 5 of the housing 4 and press-fitting the contact 1 until the protrusion 3 is received in the protrusion holding part 6 of the housing 4.
Here, the protruding portion 3 protrudes in the plate width direction while maintaining the thickness of the contact body 2, and the entire outer peripheral surface of the contact 1 at the portion where the protruding portion 3 is disposed is the inner surface of the press-fitting hole 5 of the housing 4. In the case of contact, a large force is required for press-fitting the contact 1, and at this time, a large force acts on the housing 4, and a crack may occur in the housing 4 to reduce the holding force of the contact 1.

Therefore, in the connector of Patent Document 1, as shown in FIG. 20 (B), the chamfered portion 7 is formed on the side surface of the protruding portion 3, so that the area of the front end surface of the protruding portion 3 is reduced. Has been.
According to such a contact 1, when the housing 1 is press-fitted into the housing 4, the contact area of the contact 1 with the housing 4 is reduced, the force acting on the housing 4 is reduced, and the generation of cracks can be suppressed.

  However, in the connector of Patent Document 1, the tip surface of the protrusion 3 formed at the end of the contact body 2 in the plate width direction is bitten into the inner surface of the press-fitting hole 5 of the housing 4, and the reaction caused by deformation of the housing 4 at this time is performed. Since the contact 1 is held with the holding force as a holding force, for example, when the housing 4 between the adjacent contacts 1 becomes thin in order to arrange a large number of contacts 1 at a narrow pitch, the protrusion 3 of the contact 1 There has been a problem that plastic deformation such as cracks is likely to occur in the housing 4 due to the biting of the housing. Further, if the size of the protrusion 3 of the contact 1 is reduced to avoid such a situation, there is a problem that a sufficient holding force cannot be obtained this time.

  The present invention has been made to solve such conventional problems, and even when the contacts are arranged at a narrow pitch, it is possible to ensure a sufficient contact holding force while suppressing the occurrence of cracks in the housing. It is an object to provide a connector that can be used.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
Embodiment 1
FIG. 1 shows a configuration of a connector 11 according to Embodiment 1 of the present invention. The connector 11 has a configuration in which a conductive contact 14 is press-fitted and held in a press-fitting hole 13 of an electrically insulating housing 12.
As shown in FIG. 2A, the contact 14 is formed in a flat plate-shaped contact main body 15 extending in the press-fitting direction into the housing 12, and projecting from both sides of the contact main body 15 in a direction perpendicular to the press-fitting direction. The press-fitting piece 16 is provided. The contact body 15 has a pair of parallel surfaces 15a and a pair of parallel side surfaces 15b orthogonal to the surfaces 15a, and each press-fitting piece 16 is a plate of the contact body 15 from the corresponding side surface 15b of the contact body 15. Projects in the width direction.

  Here, FIG. 2B shows a cross section of the contact 14 in the portion where the press-fitting piece 16 is formed. As shown in this figure, each press-fitting piece 16 has a pair of side surfaces 16a that gradually increase in distance from the contact body 15 in the protruding direction, and a tip surface 16b that is parallel to the side surface 15b of the contact body 15. Yes. That is, each press-fitting piece 16 has a trapezoidal cross-sectional shape in which the width gradually increases as it moves away from the contact body 15 in the projecting direction, whereby the press-fitting piece 16 is larger than the thickness D1 of the contact main body 15. It has a thickness D2. Further, since the pair of press-fitting pieces 16 protrude in the plate width direction of the contact body 15, the total width W2 of the contact 14 where the press-fitting pieces 16 are formed has a larger value than the plate width W1 of the contact body 15. doing.

  As shown in FIG. 2A, the pair of side surfaces 16a and the front end surface 16b of the press-fitting piece 16 extend in the press-fitting direction of the contact 14, respectively. An inclined surface 17 is formed to connect the tip end surface 16 b of the 16 and the side surface 15 b of the contact body 15.

On the other hand, the housing 12 is formed of a material having elasticity, and the press-fitting hole 13 has a concavo-convex cross section corresponding to the cross sectional shape of the contact 14, specifically, shown in FIGS. 3A and 3B. Thus, it has a horizontally long H-shaped cross section. That is, a cross section in which the thickness of both end portions in the width direction is expanded to D4 by connecting small second rectangles S2 in the thickness direction to the four corners of the first rectangle S1 having the width W3 and the thickness D3. In shape, four corners 18 are formed at the connection between the small second rectangle S2 and the first rectangle S1.
In advance, the width W3 of the press-fitting hole 13 is set to a value slightly smaller than the total width W2 of the contact 14, the thickness D3 is set to a value larger than the thickness D1 of the contact body 15, and the thickness D4 is set to the value of the press-fitting piece 16. Each value is set to a value larger than the thickness D2.

  When the connector 11 is assembled, the contact 14 is inserted into the press-fitting hole 13 of the housing 12 having such a cross-sectional shape. Since the width W1 and the thickness D1 of the contact body 15 are smaller than the width W3 and the thickness D3 of the press-fitting hole 13, respectively, the contact is not received from the housing 12 until the press-fitting piece 16 reaches the press-fitting hole 13. 14 can be inserted into the press-fitting hole 13.

  When the press-fitting piece 16 reaches the press-fitting hole 13, the width W 3 of the press-fitting hole 13 is set to a value slightly smaller than the total width W 2 of the contact 14. The press-fitting hole 13 is elastically expanded in the width direction by the tip end face 16b of the press-fitting piece 16 of the contact 14 until it coincides with the entire width W2 of the contact 14. At the same time, as shown in FIG. 4, the side surfaces 16a of the press-fitting pieces 16 abut against the corresponding corner portions 18 of the press-fitting holes 13, and the corner portions 18 are pressed and elastically deformed by the side surfaces 16a. . At this time, the surface 15 a of the contact body 15 does not contact the inner surface of the press-fitting hole 13 of the housing 12, and a gap is formed between them.

  As a result, in the contact 14, the front end surface 16 b and the pair of side surfaces 16 a of each press-fitting piece 16 receive a reaction force from the housing 12, and the contact area between the contact 14 and the inner surface of the press-fitting hole 13 increases excessively. The number of contact points is secured while avoiding the above. For this reason, the contact 14 can be press-fitted into the housing 12 with an appropriate pressure input, and the possibility of cracking of the housing 12 during the press-fitting of the contact 14 can be prevented, and the contact 14 can be reliably secured with a sufficient holding force. Can be held.

  As described above, the inclined surface 17 that connects the distal end surface 16b of the press-fit piece 16 and the side surface 15b of the contact body 15 is formed on the distal end side of the press-fit piece 16 with respect to the press-fit direction of the contact 14. Even if the press-fitting piece 16 reaches the press-fitting hole 13 as the contact 14 is inserted into the press-fitting hole 13, the press-fitting hole 13 is smoothly formed by the front end surface 16b of the press-fitting piece 16 simply by further press-fitting the contact 14. The corner portion 18 of the press-fitting hole 13 can be pressed and elastically deformed by being pushed and expanded in the width direction and by the side surface 16 a of the press-fitting piece 16.

The contact 14 is formed of a conductive material such as phosphor bronze. For example, after a plate having a uniform thickness is cut out from a member having a shape in which press-fitting pieces are attached to both sides of the contact body, respectively. It is possible to manufacture by compressing this member in the thickness direction using a predetermined compression mold in which the contact body portion is compressed most greatly and the compression rate decreases as it reaches the tip of the press-fitting piece. it can.
On the other hand, the housing 12 can be manufactured by molding using a material having electrical insulation and elasticity, for example, a synthetic resin such as LCP (liquid crystal polymer) or a synthetic fiber. In particular, when the size of the press-fitting hole 13 is small, it is desirable to use LCP having excellent fluidity in order to obtain a desired cross-sectional shape.

In each of the contact rows 23 and 24, the plurality of contacts 14 are aligned in the respective width directions at a predetermined pitch P1, and the contact rows 23 and the contact rows 24 each have a predetermined pitch in the thickness direction. It is formed to be arranged at P2. Furthermore, the contacts 14 in the contact row 23 and the contacts 14 in the contact row 24 are arranged in a staggered manner.

Corresponding to each contact 14, the housing 22 is formed with a press-fitting hole 13 having an H-shaped cross section similar to that formed in the housing 12 in the first embodiment.
As described in the first embodiment, the contact 14 is brought into contact with the inner surface of the press-fitting hole 13 at a large number of contact points on the front end surface 16b and the pair of side surfaces 16a of the press-fitting pieces 16, thereby allowing an appropriate pressure input. While the contact 14 is press-fitted, the contact 14 can be reliably held with a sufficient holding force. Therefore, by setting the arrangement pitches P1 and P2 to be small, even if a narrow pitch connector 21 in which the thickness of the housing 22 between adjacent contacts 14 is reduced is formed, cracks in the housing 22 are prevented. It is possible to obtain a sufficient contact holding force.

In the second embodiment, the contacts 14 of the contact rows 23 and the contacts 14 of the contact rows 24 are arranged in a staggered manner, but the present invention is not limited to this, and the contacts 14 of both contact rows are arranged in the thickness direction. Can also be aligned. However, since the respective press-fitting holes 13 have an H-shaped cross-sectional shape, the press-fitting holes 13 are smaller when the contacts 14 of the contact rows 23 and the contacts 14 of the contact rows 24 are arranged in a staggered manner. An array can be formed in the thickness direction at a pitch P2.
In the second embodiment, the plurality of contacts 14 are arranged in the two contact rows 23 and 24. Similarly, the contacts 14 may be arranged in one contact row or three or more contact rows.

In the same manner as the connector 21 of the second embodiment, the connector 31 is configured by holding a plurality of contacts 14 used in the first embodiment in a common housing 32. In the second embodiment, While the plurality of contacts 14 in each contact row are aligned in the width direction, in the third embodiment, the plurality of contacts 14 in each contact row are aligned in the thickness direction.
As shown in FIG. 8, the plurality of contacts 14 are arranged to form two contact rows 33 and 34. In each contact row 33 and 34, a plurality of contacts 14 are aligned in the thickness direction at a predetermined pitch P3. The contact row 33 and the contact row 34 have a predetermined pitch in the width direction. It is formed to be arranged in P4. Further, the contacts 14 in the contact row 33 and the contacts 14 in the contact row 34 are arranged in a staggered manner, and the contact 14 in the other row is inserted between the adjacent contacts 14 in one row. Have.

In the housing 32, corresponding to each contact 14, a press-fitting hole 13 having an H-shaped cross-sectional shape similar to that formed in the housing 12 in the first embodiment is formed.
As described in the first embodiment, the contact 14 is brought into contact with the inner surface of the press-fitting hole 13 at a large number of contact points on the front end surface 16b and the pair of side surfaces 16a of the press-fitting pieces 16, thereby allowing an appropriate pressure input. While the contact 14 is press-fitted, the contact 14 can be reliably held with a sufficient holding force. Therefore, by setting the arrangement pitches P3 and P4 to be small, even if the narrow-pitch connector 31 in which the thickness of the housing 32 between the adjacent contacts 14 is reduced is formed, the occurrence of cracks in the housing 32 is prevented. It is possible to obtain a sufficient contact holding force.

In the third embodiment, the contacts 14 of the contact rows 33 and the contacts 14 of the contact rows 34 are arranged in a staggered manner. However, the present invention is not limited to this, and the contacts 14 of both contact rows are arranged in the width direction. Can be aligned. However, if the contacts 14 of the contact rows 33 and the contacts 14 of the contact rows 34 are arranged in a staggered manner, the press-fitting holes 13 can be arranged in the width direction at a smaller pitch P4.
In the third embodiment, the plurality of contacts 14 are arranged in the two contact rows 33 and 34. However, similarly, the contacts 14 may be arranged in one contact row or three or more contact rows.

Embodiment 4
FIG. 9A shows the configuration of the contact 44 used in the connector according to the fourth embodiment. In the contact 44 shown in FIG. 2A, the press-fit pieces 16 are formed only on one side of the contact body 15 instead of the press-fit pieces 16 projecting from both sides of the contact body 15. The protrusion is formed.
That is, a press-fitting piece 16 is formed so as to protrude from one side portion 15b of the flat contact body 15 extending in the press-fitting direction in a direction perpendicular to the press-fitting direction.
As shown in FIG. 9B, the press-fitting piece 16 has a pair of side surfaces 16a that gradually increase in distance from the contact body 15 in the protruding direction, and a tip surface 16b that is parallel to the side surface 15b of the contact body 15. doing. That is, the press-fitting piece 16 has a trapezoidal cross-sectional shape that gradually increases in width as it moves away from the contact body 15, so that the press-fitting piece 16 has a thickness larger than the thickness D 1 of the contact main body 15. D2. Further, since the press-fit piece 16 protrudes in the plate width direction of the contact body 15, the total width W 4 of the contact 44 in the portion where the press-fit piece 16 is formed has a value larger than the plate width W 1 of the contact body 15. .

A housing 42 for holding the contacts 44 is shown in FIGS. 10 (A) and 10 (B). Similar to the housing 12 used in the first embodiment, the housing 42 is formed of a material having electrical insulation and elasticity, and the housing 42 has an uneven cross section corresponding to the cross sectional shape of the contact 44, specifically A press-fit hole 43 having a T-shaped cross section is formed. That is, by connecting the small second rectangle S4 to the two corners on one end side in the width direction of the first rectangle S3 having the width W5 and the thickness D3, the thickness of the end portion in the width direction is connected. Is a cross-sectional shape enlarged to D4, and two corners 48 are formed at the connecting portion between the small second rectangle S4 and the first rectangle S3.

Each value is set to a value larger than the thickness D2.

  When assembling the connector, the contact 44 is inserted into the press-fitting hole 43 of the housing 42 having such a cross-sectional shape. Since the width W1 and the thickness D1 of the contact body 15 are smaller than the width W5 and the thickness D3 of the press-fit hole 43, respectively, the contact is not received from the housing 42 until the press-fit piece 16 reaches the press-fit hole 43. 44 can be inserted into the press-fitting hole 43.

  When the press-fitting piece 16 reaches the press-fitting hole 43, the width W5 of the press-fitting hole 43 is set to a value slightly smaller than the total width W4 of the contact 44. The press-fitting hole 43 is elastically expanded in the width direction by the tip end face 16b of the press-fitting piece 16 of the contact 44 until it coincides with the entire width W4 of the contact 44. At the same time, as shown in FIG. 11, the pair of side surfaces 16a of the press-fitting pieces 16 abut against the corresponding corners 48 of the press-fitting holes 43, and the corners 48 are pressed and elastically deformed. At this time, the surface 15a of the contact main body 15 does not contact the inner surface of the press-fitting hole 43 of the housing 42, and a gap is formed between them.

As a result, the contact 44 receives the reaction force from the housing 42 on the tip surface 16b of the press-fitting piece 16, the pair of side faces 16a, and the side face 15b of the contact body 15 on the side where the press-fitting piece 16 is not formed. And an excessive increase in the contact area between the inner surface of the press-fitting hole 43 and a large number of contact points are secured. For this reason, the contact 44 can be press-fitted into the housing 42 with an appropriate pressure input, the possibility of cracking of the housing 42 when the contact 44 is press-fitted is prevented, and the contact 44 is securely held with a sufficient holding force. It becomes possible to do.

By contacting the inner surface of the hole 43, the contact 44 can be reliably held with a sufficient holding force while the contact 44 is press-fitted with an appropriate pressure input. Therefore, by setting the arrangement pitches P5 and P6 to be small, even if the narrow pitch connector 51 in which the thickness of the housing 52 between the adjacent contacts 44 is reduced is formed, the occurrence of cracks in the housing 42 is prevented. It is possible to obtain a sufficient contact holding force.
