Description

Connector with a locking member

Technical Field

The present invention relates to a connector, and more particularly, to a connector for a card reader.

Background

Static electricity is ubiquitous in life and affects delicate electronic or circuit components, especially, the volume of the electronic or circuit components is very small, and slight static electricity may cause damage to the components. For example, if two objects have Static electricity but the electrostatic potentials of the two objects are different, the two objects may be close to each other to generate charge transfer, which is electrostatic Discharge (ESD). Because energy is released and high temperature is generated during electrostatic discharge, the released energy or the generated high temperature may damage peripheral components, thereby damaging the device.

For example, the connector in the prior art includes a substrate, a circuit board, and an electrical connector, wherein two ends of the electrical connector are respectively soldered to the substrate and the circuit board and electrically connected to each other, so that if static electricity on the substrate is released to the circuit board through the electrical connector, the static electricity generated by friction between the substrate and an object connected to the substrate during use is prevented from accumulating on the substrate, and finally the static electricity is discharged to damage peripheral components. However, the theoretical effect of the above structure is different from the effect that can be achieved in practice, and the increased load capacity is still not really avoided as the phenomenon of electrostatic discharge.

In view of the above, a better solution is proposed, and a problem to be solved is needed in the art.

SUMMERY OF THE UTILITY MODEL

The main object of the present invention is to provide a connector which can release accumulated static electricity.

To achieve the above object, the present invention provides a connector having:

a substrate having a first side and a second side opposite to each other; the substrate further has:

at least one column integrally formed with the substrate and protruding from the first side of the substrate;

a circuit board which is grounded and fixedly arranged on the substrate and is electrically connected with the substrate through the at least one column; and

a pin module electrically connected to the circuit board.

Optionally, in the connector, each of the at least one cylinder is hollow.

Optionally, the connector further has at least one abutting member protruding from the second side of the substrate.

Optionally, in the connector, the substrate has two abutting pieces, and the pin module is located between the two abutting pieces.

Optionally, in the connector, each of the abutting members is L-shaped, and has a first arm and a second arm connected to each other, the first arm is fixedly disposed on the substrate, and the second arm is parallel to the second side surface of the substrate; the second arm forms a protrusion that protrudes in a direction away from the second side of the substrate.

Therefore, the utility model has the advantages that the base plate passes through the cylinder and is connected with the circuit board electricity of ground connection, therefore the base plate also is ground connection. Because the column is formed integrally with the substrate, the resistance of conducting static electricity between the substrate and the circuit board is greatly reduced. Therefore, if the substrate has static electricity, the cylinder can conduct the static electricity on the substrate to the circuit board, and the static electricity is more effectively released.

Detailed Description

The following description of the preferred embodiments of the present invention will be made in conjunction with the drawings and the accompanying drawings to further illustrate the technical means adopted to achieve the objects of the present invention.

Please refer to fig. 1 to fig. 4. The utility model provides a connector, it can supply a chip card A (smart card) to insert and be connected with chip card A. The present invention provides a connector having an outer housing 11, an inner housing 12, a substrate 20, a circuit board (not shown), and a pin module 30. The inner housing 12 is fixed in the outer housing 11 and forms an accommodating space and an opening 13, and the opening 13 is communicated with the accommodating space. Therefore, the chip card A can enter the accommodating space from the opening 13, and the chip of the chip card A can be positioned in the accommodating space. The substrate 20, the circuit board, and the pin module 30 are all fixed in the inner housing 12.

The substrate 20 is made of a conductive material, and the substrate 20 is electrically connected to the inner housing 12, so as to absorb static electricity generated on the inner housing 12. Specifically, the substrate 20 is provided with a plurality of fasteners for being fixed to the inner housing 12, and the substrate 20 is electrically connected to the inner housing 12 via the fasteners. The substrate 20 has a first side surface and a second side surface opposite to each other, and the first side surface faces downward and the second side surface faces upward. The base plate 20 has at least one column 21 and optionally at least one abutment 22. The following description is given by way of example of the embodiment in which the substrate 20 has two pillars 21 and two abutments 22, but the number of the pillars 21 and the abutments 22 is not limited thereto.

Please refer to fig. 5 to 8. Each post 21 is integrally formed with the base plate 20 and projects from a first side of the base plate 20. In the present embodiment, each of the pillars 21 is hollow, so the substrate 20 and the pillars 21 can be made by stamping a metal plate, but not limited thereto. In this embodiment, the two pillars 21 are respectively adjacent to two opposite sides of the substrate 20.

Please refer to fig. 5, fig. 6, fig. 9, and fig. 10. Each abutment 22 projects (i.e., projects upwardly) from the second side of the base plate 20 and may likewise be integrally formed with the base plate 20, but is not so limited. In this embodiment, each abutting member 22 is L-shaped and has a first arm 221 and a second arm 222 connected to each other, the first arm 221 is fixed to the substrate 20, and the second arm 222 is parallel to the second side surface of the substrate 20. The second arm 222 forms a projection 223, and the projection 223 projects away from the second side of the substrate 20. In other words, the convex portion 223 is upwardly convex.

The circuit board is grounded and fixed on the first side of the substrate 20, and is electrically connected to the substrate 20 through the column 21. Therefore, if there is static electricity on the substrate 20, the pillars 21 can conduct the static electricity on the substrate 20 to the circuit board, so as to prevent the static electricity from accumulating on the substrate 20. Particularly, the middle column 21 of the present invention is integrally formed with the substrate 20, so that the resistance of conducting static electricity between the substrate 20 and the circuit board is greatly reduced, and the accumulation of static electricity on the substrate 20 can be more effectively avoided. Since the substrate 20 is also electrically connected to the inner housing 12, the static electricity on the inner housing 12 can be conducted to the circuit board through the substrate 20 via the above path and then grounded.

The pin module 30 is electrically connected to the circuit board, and the pin module 30 is used for electrically connecting to the chip card a. In other words, the chip card A is electrically connected to the circuit board through the pin module 30. In the present embodiment, the pins of the pin module 30 extend from the circuit board located on the first side of the substrate 20 to the second side of the substrate 20, and form a gap with the second side of the substrate 20. When a chip card a is inserted into the opening 13 of the connector of the present invention, the chip card a is located between the pins and the second side of the substrate 20. When the chip card a is located between the pins and the second side of the substrate 20, the abutting member 22 will push the chip card a toward the pins, so as to ensure that the chip card a and the pins stably abut against each other and maintain the state of electrical connection. In this embodiment, the pin module 30 is located between the two abutting members 22, so that the chip cards a can be pushed to the pins evenly, and stable electrical connection can be formed. Because the chip card A is often charged with static electricity due to contact with human body or generates static electricity due to friction when being connected with the connector, when the chip card A is arranged between the substrate 20 and the pins, the static electricity can be transferred to the substrate 20 through the contact of the abutting piece 22 and the chip card A, and therefore, the chip card A can achieve the effect of grounding through the substrate 20 and the circuit board.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and although the present invention has been disclosed with the preferred embodiment, but not limited to the present invention, any skilled person in the art can make some modifications or equivalent changes to the technical content disclosed above without departing from the technical scope of the present invention, but all the technical matters of the present invention are within the scope of the technical solution of the present invention.
