Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is applicable to multi-pin components such as large-scale integrated circuit modules,
The present invention relates to a connector socket such as a multi-pin connector, and particularly relates to a connector socket equipped with a contact holding mechanism that imparts straightness to socket contacts that fit into connection pins.

[Conventional technology]

Conventionally, socket contact holding structures in connector sockets have been described, for example, in the document "Connector Latest Technology," published by Sogo Gijutsu Publishing, April 10, 1987.

As described in "Pages 314 to 315," the entire surface of the contact holding part is held by molding within the housing of the socket to improve the straightness of the contacts (see FIG. 20). This socket contact holding structure is used as the seventh
This will be explained with reference to the drawings and FIG.

FIG. 7 is a sectional view of a main part of a conventional connector socket. Moreover, FIG. 8 is a sectional view of the main part of the connector socket in a state in which the connecting pin of the connector is inserted. In FIGS. 7 and 8, the socket contact 3 is formed by molding an elastic conductive metal piece, and as shown in the figure, has an opposing spring piece 3a that contacts the connection pin, and a fulcrum part of the spring piece. a contact holding part 3b, a contact fixing part 3C,
It has a structure having a contact lead portion 3d serving as a conductive terminal. This socket contact 3 is housed in the connector housing 1, and the connector socket 1
Configure 0. The connector housing 1 is composed of an upper connector housing 1b and a lower connector housing 1a. A socket contact 3 is housed in the lower connector housing 1a, and the upper connector housing 1b is bonded to form a connector socket 10.

That is, the connector socket 10 accommodates the socket contact 3 in a contact storage portion formed in the lower connector housing 1a, leads out the lower contact lead 2 of the socket contact 3 from the lower connector housing 1a, and connects the root portion of the contact 3 to the contact housing 1a. contact fixing part 3
C is fixed to the lower connector housing 1a, and the upper connector housing 1b is bonded to the lower connector housing 1a. The straightness of the socket contacts 3 in this connector socket is maintained by the contact holding portion 3b and the housing portion being in contact with each other. Therefore, in order to ensure sufficient straightness, the contact portion between the contact holding portion 3b and the housing portion is made long. However, in this case, if the contact portion between the contact holding part 3b and the housing part is lengthened, it will not be possible to secure enough space between the spring piece 3a at the tip of the contact and the connector housing 1, and the movable part of the spring piece 3a will be reduced. As a result, the connector socket requires a high insertion force when inserting the connecting pin.

FIG. 8 is a sectional view of the main part of the connector socket with the connecting pin of the connector inserted. FIG. 8 shows a state in which the socket contact 3 and the connecting pin 4 of the connector are fitted together.

The straightness of the socket contact 3 is essential in order to guide the connection pin 4 and insert the connection pin so that the connection pin 4 and the socket contact 3 are in contact with each other without abnormal stress. When the connecting pin 4 is inserted,
As shown in the figure, the spring piece 3a of the socket contact 3 is pushed apart by the connecting pin 4 and approaches the connector housing 1. If there is not enough space in the contact housing when the connecting pin 4 is inserted and fitted, when the spring piece 3a at the tip of the contact comes into contact with the connecting pin 4, unreasonable stress will be applied to the spring piece 3a and the spring characteristics will deteriorate. changes,
As a result, it will be plastically deformed and will no longer function as a contact. Moreover, the same thing will happen when the connecting pin 4 swings inside the contact storage part of the connector housing 1.

In order to prevent this, the space in the contact storage section of the connector housing 1 can be increased, but in this case, as mentioned above, the contacts 3 are fixed to the connector housing 1 only by the contact holding parts 3b, and the contacting parts When this decreases, there is a problem that the socket contact holding structure does not have a predetermined straightness.

For the contact housing portion of the connector housing 1, there is a method of making only the contact holding portion 3b narrow and widening the upper part, but in this case as well, in order to maintain the straightness of the socket contact, the length of the contact holding portion 3b must be set. A predetermined length is required, and the shape obstructs the movement of the spring piece 3a at the upper end of the contact. In a high-density connector socket, the contact accommodating portion of the connector housing 1 is required to have high dimensional accuracy, and is subject to significant restrictions in terms of mounting.

[Problem to be solved by the invention]

In this way, when configuring a high-density connector socket, for example, a module connector with as many as 2500 connection pins or a connector socket for multi-pin components, the connection pins and socket contacts when the pin connector is inserted into the socket. Considering the condition when the pin is fitted, there is a risk that the tip of the contact will swing due to the lateral movement of the pin and hit the housing, causing plastic deformation of the spring. For this reason, when the socket contact accommodating portion of the housing is widened, the predetermined distance between adjacent socket contact accommodating portions in a high-density connector socket disappears.
This has the problem of being limited by the strength required to hold the socket contact.

In other words, in the conventional technology, when configuring the contact holding mechanism of a connector socket, the contact portion between the contact holding part and the housing part is made long and straightened dust is formed.
The upper space in the contact accommodating portion of the housing is reduced, and the movement of the contact spring is restricted by the wall of the housing when the connecting pin of the connector is inserted. This results in an increase in the insertion force of the connector pin and, in turn, plastic deformation of the spring. On the other hand, if the contact storage area of the housing is widened to prevent this, the socket contact will be fixed only by the contact lead part at the lower end, which will worsen the problem of straightening of the socket contact. There is.

The present invention has been made to solve the above problems.

SUMMARY OF THE INVENTION An object of the present invention is to provide a connector socket having a contact holding mechanism that ensures that the straightness of the socket contacts is at least a predetermined value and that does not inhibit the movement of the socket contacts during pin fitting.

The above and other objects and novel features of the present invention will become apparent from the description of this specification and the accompanying drawings.

[Means to solve the problem]

In order to achieve the above object, in the present invention, in a connector socket having a socket contact for a connecting pin and a housing part for storing and holding the socket contact, a spring part is provided in the socket contact holding part to accommodate the socket contact. The contact retaining mechanism is characterized in that a contact holding mechanism is provided in which a protrusion is formed at a position facing the spring portion in the housing storage portion.

[Effect]

According to the above means, a spring portion is provided in the socket contact holding portion of the connector, and a protrusion portion is formed at a position facing the spring portion in the housing storage portion that accommodates the socket contact. This protrusion is formed when molding the housing.

As a result, when the socket contact is fixed in the storage part of the housing, the spring part of the contact holding part and the protruding part of the mold come into contact to form a contact holding part structure, and the straightness of the socket contact is maintained when it is stationary. It will be done. Other than the protruding part of the housing part, there is enough space for the movement of the socket contact, and when the connecting pin is mated,
Even if the socket contact expands, it can still move without coming into contact with the mold wall of the contact accommodating portion of the housing. In addition, even if the connecting pin swings from side to side, the spring of the contact support part of the socket contact follows, preventing abnormal deformation of the socket contact, and when the connecting pin is pulled out, the spring of the support part of the contact holding mechanism follows. It will return to the center.

In this way, the socket contact in the connector socket is held in the housing by the contact fixing part at the base of the contact lead, and the predetermined straightness of the housing is achieved by pressure contact support between the spring part and the protrusion on both sides of the contact holding part. This can be achieved by supporting the mechanism in its housing compartment. For this reason, here, the contact holding portion is provided with a notch having spring properties, and the housing is provided with protrusions facing each of the notch positions. The sides other than this protrusion are provided with extra space for the socket contact. As a result, the only part other than the contact fixing part that is in contact with the connector housing is the part with the spring of the contact holding part, which makes it possible to reliably remove straightening dust, and also to prevent the contact from mating with the pin. The movement of the connecting pin can be followed by the support of the spring in the holding part, and since the housings on both sides are not close together, there is no contact or deformation of the socket contact, and when the connecting pin is removed, the socket contact is located in the center. It works so that it returns to straightness and dust is retained.

〔Example〕

Hereinafter, one embodiment of the present invention will be specifically described using the drawings.

Note that throughout the explanation of this embodiment, the same elements are given the same reference numerals, and repeated explanations thereof will be omitted.

FIG. 1 is a perspective view showing the appearance of a socket connector according to an embodiment of the present invention. As shown in FIG. 1, the connector socket 10 has a connector housing 1 provided with a large number of pin insertion holes 11, and a socket contact provided inside each pin insertion hole 11.

It is constructed by pulling out a contact lead 2 from a socket contact.

FIG. 2 is a sectional view of essential parts of a connector socket according to an embodiment of the present invention. FIG. 3 is a cross-sectional view of the main part of the connector socket shown in FIG. 2, taken along the line ■-■. Moreover, FIG. 4 is a perspective view of the socket contact to be accommodated. Figures 2 and 3.

This will be explained with reference to FIG. The socket contact 3 is formed of an elastic conductive metal piece and, as shown in the figure, includes an opposing spring piece 3a that contacts the connection pin, a contact holding part 3b that serves as a fulcrum of the spring piece, and a conductive terminal. It has a structure having a contact lead portion 3d.

Here, a contact holding spring portion 6 is formed in the contact holding portion 3b. This socket contact 3 is housed in a connector housing 1 to constitute a connector socket 10. The connector housing 1 is composed of an upper connector housing 1b and a lower connector housing 1a, and a housing protrusion 5 is formed in a contact accommodating portion of the connector housing 1 at a position facing the contact holding spring portion 6. Lower connector housing 1
A connector socket 10 is formed by housing the socket contact 3 in the upper connector housing 1b and gluing the upper connector housing 1b.

When the contact is stored, it comes into contact with the contact holding spring section 6. As a result, the socket contact 3 is supported by pressure contact between the contact holding spring portion 6 and the housing protrusion portion 5 at two locations with respect to the contact fixing portion 3c at one location.
Straightness is maintained when supporting the socket contact 3. Therefore, the housing on the side of the five-socket contact 3 can have a space without coming into contact with the socket contact 3. Therefore, there is enough space between the spring piece 3a at the tip of the contact and the connector housing 1, so that when the socket contact 3 is fitted with the connecting pin, the spring piece 3a does not come into contact with the connector housing 1, and the spring piece 3a can move normally. Can be contacted due to spring characteristics. Also,
Even when the connecting pin swings during insertion, the contact holding spring portion 6 allows the socket contact 3 to follow the connecting pin without being plastically deformed. Further, even after the connecting pin is removed, the contact holding spring portion 6 allows the contact holding mechanism to return to the center and maintain straightness at all times.

FIG. 5 is a cross-sectional view showing the main parts of a socket connector according to another embodiment of the present invention. FIG. 6 is a perspective view of a socket contact according to another embodiment of the present invention. In this other embodiment, as shown in the figure, the protrusions provided on the wall of the contact accommodating portion of the housing are provided at four locations in four directions, and the contacts are supported by contacting and supporting the protrusions at the four points. I'm trying to give it straightness. In this case, it is sufficient for the contact holding spring portions 6 provided in the contact holding portion 3b to be provided in two opposing directions in the same direction as the opposing spring piece 3a in contact with the connection pin, and the remaining two orthogonal directions are particularly limited to the spring portions. It is not necessary to provide Also,
Of course, a configuration may be adopted in which spring portions are provided in four directions corresponding to the four protrusions provided on the wall of the bousing.

As described above, the contact holder spring and the housing protrusion are merely examples, and the present invention is applicable to other shapes and methods of arranging a large number of them.

The present invention has been specifically explained above based on examples, but
It goes without saying that the present invention is not limited to the embodiments described above, and can be modified in various ways without departing from the spirit thereof.

〔Effect of the invention〕

As described above, according to the present invention, the contact holding mechanism is provided by pressure contact between the spring part provided in the contact holding part and the housing protrusion, so that the connecting pin is always aligned when mating. Since the other parts can have a space with the housing, the movement of the contact can be displaced without being restricted by the housing when the pin is fitted.

Since the holding portion has a spring property, the displacement when the connecting pin is inserted has good followability, and after the pin is removed, it returns to the center immediately and straightness can be maintained. In addition, by providing the holding portion with spring properties, contact alignment becomes easier during connector manufacturing, and workability is significantly improved.
