Abstract

An electronic component connectable to a connector includes a pair of contacts attached to a base of a housing, and an actuator. The actuator comprises two slat members placed on top of each other. The free ends of the pair of contacts are located in the contact apertures of the slat member. The contacts are first erected before the actuator is operated. When the slat member slides in the opposite direction, the free end of the contact moves farther. After inserting the substrate terminals of the electronic assembly between the free ends and releasing the actuator, the contacts will attempt to return to their original positions due to their flexibility and thus firmly secure the terminals.

Description

Electronic component connectable to a connector

Technical Field

The invention relates to the technical field of connectors and electronic components connectable to the connectors, in particular to a connector and an electronic component connectable to the connector.

Background

In order to efficiently transmit a large number of signals, rapid signal transmission and high-density mounting of electronic devices have become increasingly required in recent years. Along with this trend, miniaturization and multi-polarization of connectors are being developed.

In order to meet the above requirements, conventional connectors are arranged with electrical contacts (terminals) having columnar signal pins (terminals) inserted in the axial direction. The contacts are provided with contact areas that compress the outer edges of the signal pins in a diametrical direction. In this case, the contact pressure of each connector can be reduced. However, as the number of signal pins increases, an increase in force for mounting and dismounting the connector as a whole is required, making mounting and dismounting of the connector difficult.

The connector itself may be damaged during the mounting or dismounting of the connector, or a contact electronic component such as an LSI device may be damaged. Therefore, there is a need to substantially eliminate the force required to install and remove the connector.

The connector shown in fig. 1 includes: the assembly shown in fig. 1 is typically used to reduce the force required to install and remove the connector.

The connector 1 is composed of a base 3 comprising contacts 2, an actuator 4 and a cover 5.

The base 3 has a plurality of contacts 2 supported in a cantilever fashion. The actuator 4 has a free end portion 2 contacting the one to which the contact hole 4 is fitted. In addition, the actuator 4 includes a pair of slidable members that can slide on the base 3 in the lateral direction as indicated by the arrow. The cover 5 has an opening 5 one which guides an outer edge 6 of the LSI device and holds the actuator 4 slidably.

When the actuator 4 of the push portion 4b is pressed in the pattern indicated by the arrow. 1 to the pair of actuators, 4, the free end 2 of the contact fitting into the contact hole 4. 4 of each member of one actuator fits against 4 walls Ç defining 4 through the contact hole, and moves to the dotted liner position figure. 1 from the normal position. Under such conditions when the LSI apparatus 6 is mounted in the connector 1, the signal pin 6-the 6 of the LSI device-is fitted to the connector 1 with little required force without rubbing the contacts 2. The contact 2 resumes its normal position pushing portion and when 4b is released, the contacts 2 contact one of the signal pins 6. Thus, the connector 1 and the LSI apparatus 6 are electrically connected.

However, the conventional connector 1 is insufficient in providing a constant and stable electrical connection because each contact 2 is pressed against only one side of the signal pin 6a of the LSI device 6. Even if the window and the material 2 of the contact are redesigned to increase the contact pressure to stabilize the connection, there is a possibility of a damaged signal pin 6-the connector 6 of the LSI device and the connector 1 of the contact 2 are repeatedly mounted and demounted after itself.

Generally, for signal transmission, unbalanced transmission is widely adopted from the viewpoint of cost saving. However, due to the growing trend of fast signal transmission and high-density mounting of electronic equipment, especially when fast signal transmission is employed, unbalanced transmission is likely to be affected by noise. Therefore, there is a tendency to adopt balanced transmission. In this case, the conventional connector easily achieves rapid signal transmission, but sacrifices high-density mounting due to the structural characteristics of the connector requiring two signal pins.

Typically, a common ground contact is provided on the substrate of an electronic device, in addition to a large number of signal pins. However, when each of the signal pins is arranged in close proximity to each other to cope with the demands of fast signal transmission and high-density mounting of electronic equipment, the connector tends to be affected by noise. In order to solve the above problem, a pair of ground contacts and signal pins are introduced, but in this case, it is likely to affect high-density mounting of electronic equipment.

Disclosure of Invention

It is therefore a general object of the present invention to provide a connector and an electronic component connectable to the connector, which can solve the above-mentioned problems.

It is another more specific object of the present invention to provide a connector and an electronic part connectable to the connector, which is not damaged by repeated connection and disconnection therebetween.

The connector of the present invention comprises at least one pair of adjacent contacts having flexible free ends, which are arranged to face each other, wherein the at least one pair of adjacent contacts hold terminals of a connected electronic component to form an electrical connection.

The present invention enables electronic equipment to be mounted at high density for rapid signal transmission. In particular, since a pair of adjacent contacts hold the terminals of the electronic component from both sides, stable electrical connection can be provided. Furthermore, the possibility of damaging the terminals or contacts themselves of the electronic component is reduced.

The connector of the present invention further comprises an actuator for adjusting the distance between the free ends of at least one pair of adjacent contacts. The actuator includes two strap members disposed one on top of the other, the strap members having apertures through which the free ends of at least one pair of adjacent contacts are positioned. When the two slat members are pushed in opposite directions, the contact walls of the apertures of the two slat members come into contact to push the free ends of at least one pair of adjacent contacts apart. The present invention enables the connector to be connected to and disconnected from the electronic device terminal with a small force, thereby protecting the contacts.

In addition, the free ends of at least one pair of adjacent contacts are rounded and slightly offset in height with respect to each other. Likewise, the contact wall of the aperture of the slat member is circular-arc shaped. Since the apexes of the arcs of the free ends of at least one pair of contacts are aligned with the apexes of the arcs of the contact walls of the slat members, a force is applied to the arcs only in the horizontal direction. The free end ends when the actuator is depressed. In short, the force is applied only in the slidable direction of the slat member. Since no force is applied in the vertical direction to increase the frictional force between the two slat members, the actuator can be operated smoothly.

When at least one pair of adjacent contacts consists of a ground contact and a signal contact, the electronic device terminals can be arranged close to each other, thereby achieving high-density mounting of electronic devices for rapid signal transmission.

When at least one pair of adjacent contacts is constituted by a pair of signal contacts connected in parallel, the influence of noise can be reduced, and the terminals of the electronic device can be arranged close to each other, thereby achieving more preferable high-density mounting.

The electronic parts related to the present invention can be connected to the connector described in the present invention. The component includes a three-layer terminal formed of a pair of terminals with an insulating material therebetween.

Detailed Description

A description will now be given of the connector and the electronic components of the embodiments of the present invention with reference to the provided drawings.

Fig. 2 is a perspective view, and fig. 2 is a perspective view. Fig. 3 shows a cross-section of the connector 10 of the present invention.

The connector 10 includes a housing 12, contacts 14 and an actuator 16.

The housing 12 is made of an insulating material and has a base 20 with four walls, 22 one to 22 d, extending from the base 20. Facing each other, two of the walls, 22 one and 22 Ç, extend further upward than the other two walls and form guides (22 one and 22 Ç mentioned below).

Base 20 supports three pairs of contacts 14, wherein each contact 14 includes one contact 14 and a contact 14 b. As shown in fig. 1. As shown in fig. 2, the contacts 14 are arranged in two rows. Each contact 14 of the respective sets of contacts 14 a and 14b has a respective radiused free end 24 b and 24 a, respectively, which is disposed at facing positions slightly offset to upper and lower positions, respectively. In addition, contacts 14 one and 14b are electrically isolated or insulated by a base from each other 20.

The slat members 16 a and 16B each include a contact hole 26 a surrounded by four flat walls and contact holes 26B, which are circular arc shaped in fig. 3 as viewed in a direction 1-X2 of the X-wall B. The contact holes 26 one and 26 b are arranged at a certain pitch. In addition, contact holes 26-16 a, 16 b of one of the slat members and contact holes 26 b-16 a, 16 b of the other of the slat members are paired to communicate with each other. Each of the contacts 14 a and 14b of the circular arc-shaped free end portions 24 a and 24 b is arranged to pass through a corresponding pair of the corresponding contact holes 26 one by one.

One at the distal end 16 of the X1 slat member is an operating portion 28. Similarly, the distal end 16 b of the X2 slat member is an operating portion 28 b. When the two operating portions 28 one and 28 b are pressed in the pattern indicated by the corresponding, adjacent arrows. 3, the arc wall B26 b of the contact hole pushes the strip member 16 b in the X1 direction. On the other hand, the contact hole 26 has a strip portion 16 b pushing the contacted portion a 14 one in the X1 direction. Meanwhile, the wall b 26 b of the contact hole of the circular arc shape pushes a contacted portion a 14b of the strip member 16 in the X2 direction. As a result, 14 a and 14b of each pair of contacts of the radiused free end 24 are moved further apart from each other.

A description will now be given of the operation of the connector 10 with reference to fig. 2.

In fig. 4a is shown the ("at rest") state before operation of the connector 10 corresponding to fig. 3A. 3. Contacts 14 one and 14b are upright because slat members 16 one and 16 b are not urged toward each other. In this case, the tips 24 a and 24 b, respectively, are separated by a distance l.

In fig. 4B, reference numeral 30 denotes a substrate of an electronic component relating to an embodiment of the present invention, and reference numeral 32 denotes a terminal mounted on the substrate 30. Terminal 32 is a pair of terminal clamps 32 b and 32 Ç of one of three-layer terminal 32 made of insulative material. Is sufficiently wider than the length L between the tips of the contacts by 14 and 14 turns.

In fig. 4B, when the first and second operation portions 28B and 28B are pressed by the compressive force, the slat members 16 are pressed in the X-slide 2 direction and the slat members 16B are pressed in the X-slide 1 direction. By so doing, the contacted portion a 14b passes through the wall b 26 b of the contact hole in the X push 2 direction one of the slat members 16. On the other hand, the contacted portion A14 is a strip member in a direction 26B in which X is pushed 1 through the wall B of the contact hole. As a result, the free ends 24 a and 24 b contact 14 a and 14b, respectively, are pushed into the actuated state further away from the width W terminal 32. In this actuated state, the terminal 32 is inserted at 30 of the substrate between the contacts 14 one and 14b of the free end 24, so that the pressure 28 one and 28 b applied in the operative part when the terminal 32 b faces the contact 14 one and the terminal 32 Ç faces the contact 14 bay is slowly released, as shown in fig. 4C, the contacts 14 one and 14b in part a are pushed against the wall of the contact hole 26 b. As a result, the contacts 14 one and 14b are brought together. The contacts 14 one and 14b attempt to recover the separation length L, which is shorter than the width w, with sufficient pressure to hold the terminals 32 so that the electronic component and the connector 10 are securely electrically connected.

One example of a method of manufacturing the terminal 32 of the substrate 30 will now be described with reference to fig. 1. Refer to fig. 5A to 5B.

An insulating material 32 is placed on top 30 of the substrate using a suitable method. Next, a pattern 40 is formed on the substrate 30.

The substrate 30 is covered by a mask 44 except for certain spaces 42 on both sides of the insulating material 32 a.

Then, the terminals 32 b and 32 c are formed in the space 42 so as to be connected to the pattern 40.

The tri-layer terminal 32 has a pair of terminals of insulative material 32 held between 32 b and 32 c ^ 44 (FIG. 5D) fabricated by removing the mask.

With the above-described embodiments of the present invention in relation to the connector 10 and the substrate 30, a more efficient high-density mounting of electronic devices for fast signal transmission can be achieved. In particular, since the pair of contacts 14 one and 14b hold the terminals 32 from both sides of the substrate 30, electrical connection can be ensured, and there is a reduced likelihood of damage to the terminals 32 or to the contacts 14 one and 14b themselves. In addition, by pressing the actuator 16, it is possible to connect the connector 10 to the substrate 30 of the terminal 32 with a small force for mounting and removal, and the terminal damage 32 or the contacts 14 a and 14b themselves are reliably prevented.

Fig. 6 is a comparative example of the connector 10. As shown in fig. 1. If all walls 26 Ç of the contact hole are flat and uniform, and also if the tops 14 a and 14b of the free ends of the contacts are curved, the actuator, when 16 is depressed, a force is added diagonally as shown by arrow X1 in fig. 1. 6 at slat member 16 Ç and add force in a diagonal direction, indicated by arrow X2 in FIG. 6 at slat member 16 d. As a result, the increased friction experienced by the slat members 16 Ç and 16 d prevents the actuator 16 from operating smoothly from the horizontal direction, as shown. 6. On the other hand, as with fig. 4B, which is shown in connector 10, force is applied only horizontally to the slat members 16 a and 16B.

The above-described embodiments of the connector 10 of the pair of contacts 14 one and 14b relating to the present invention may be combined and considered a single contact 14 which transmits a signal. In addition, the pair of terminals 32 b and 32 c ^ substrate 30 can be considered a single terminal 32 to transmit.

As another alternative to the above, it is also possible to apply the pair of contacts 14 one and 14b as ground contacts and signal contacts and, in correspondence, the terminals 32 applied to the terminals 32 b and 32 c terminal as ground terminals and signal terminals. In this case, the electronic terminals can be arranged close to each other, and more efficient high-density mounting of the electronic apparatus for rapid signal transmission can be achieved.

As another alternative, it may employ contacts 14 a and 14b as a pair of parallel signal contacts and, in correspondence, terminals 32 b and 32 c as parallel terminals. In this case, the influence of noise can be reduced. In addition, the electronic terminals can be arranged close to each other, thereby achieving more efficient high-density mounting of the electronic apparatus for rapid signal transmission.

In addition, the substrate 30 according to the preferred embodiment of the present invention can also reduce inductance.

The present invention is not limited to the specifically disclosed embodiments, and variations and modifications may be made without departing from the scope of the present invention.
