Description

Electrical connector

Technical Field

The present invention relates to an electrical connector for electrically connecting an electric wire and a circuit board to constitute an electric circuit.

Background

In order to electrically connect electronic components arranged at a distance from each other, a Flexible Flat Cable (FFC), a Flexible Printed Circuit (FPC), or the like is widely used. The flexible flat wire and the flexible printed circuit (hereinafter, collectively referred to as "wires") have a structure in which a plurality of terminals are arranged in parallel in the width direction at the wire tip. Such electric wires are detachably connected to an electric connector mounted in the circuit board and electrically connected to the circuit board with the electric connector as a medium.

Generally, the work of connecting the electric wire to the electric connector is performed by manual work. This operation is composed of three processes, i.e., a first process of rotating the actuator that is in the closed state to open the actuator, a second process of inserting the electric wire into the electrical connector, and a third process of closing the actuator to fix the electric wire.

Among these three processes, since the electrical connector is shipped with the actuator closed, the first process of rotating the actuator in the closed state to open is equivalent to a pre-requisite process for inserting the electric wire into the electrical connector. However, in terms of the operation speed, this process acts as a factor of delaying the entire operation of connecting the electric wire to the electric connector.

SUMMERY OF THE UTILITY MODEL

A first object of the present invention is to provide an electrical connector capable of simplifying an operation of connecting an electric wire to the electrical connector.

A second object of the present invention is to provide an electrical connector capable of minimizing damage to a terminal portion of an electrical wire in a process of connecting the electrical wire to the electrical connector.

In order to achieve the first object of the present invention, the present invention discloses an electrical connector, comprising: a housing including a wire housing portion opened forward and a terminal fixing portion located rearward of the wire housing portion; a terminal mounted on the terminal fixing portion and having a connection portion protruding from a bottom surface of the wire housing portion; and an actuator formed to be rotatable between a closed state configured to cover the terminal fixing portion and an open state exposing the terminal fixing portion, the actuator including: an actuator body; and a contact portion configured to be at least partially laterally overlapped with the through portion in the closed state, and to function to be rotated to the open state by being pressed by the electric wire inserted into the electric wire housing portion in the closed state.

Further, in order to achieve the first object of the present invention, there is also disclosed an electrical connector comprising: a housing including a wire housing portion opened forward and a terminal fixing portion located rearward of the wire housing portion; a terminal mounted on the terminal fixing portion and having a connection portion protruding from a bottom surface of the wire housing portion; a hook mounted to a hook fixing part formed at both sides of the case and defining a support shaft accommodating part together with the case; and an actuator formed to be rotatable between a closed state configured to cover the terminal fixing portion and an open state exposing the terminal fixing portion, the actuator including: an actuator body; a support shaft that is formed to protrude from both left and right sides of the actuator main body and is accommodated in the support shaft accommodating portion; and a contact portion that is located below the support shaft in the closed state and that rotates to the open state by being pressed by the electric wire inserted into the electric wire housing portion in the closed state, wherein an interval from a bottom surface of the electric wire housing portion to the contact portion is smaller than a thickness of a tip portion of the electric wire.

In order to achieve the second object of the present invention, the present invention discloses an electrical connector comprising: a housing including a wire housing portion opened forward and a terminal fixing portion located rearward of the wire housing portion; a terminal mounted on the terminal fixing portion and having a connection portion protruding from a bottom surface of the wire housing portion; a hook mounted to a hook fixing part formed at both sides of the case and defining a support shaft accommodating part in a closed loop form together with the case; and an actuator formed to be rotatable between a closed state configured to cover the terminal fixing portion and an open state exposing the terminal fixing portion, the actuator including: an actuator body; a support shaft that is formed to protrude from both left and right sides of the actuator main body and is accommodated in the support shaft accommodating portion; and a contact portion configured in the closed state such that at least a part thereof laterally overlaps the through portion, and functioning in the closed state to be rotated to the open state by being pressed by the electric wire inserted into the electric wire housing portion, the support shaft being formed to move from one side to the other side of the support shaft housing portion when the actuator is switched from the closed state to the open state.

According to an example of the present invention, the contact portions may be formed on both left and right sides of the actuator main body, respectively, and disposed outside the terminal.

It may be that the actuator further includes: and a pressing part alternately arranged in a lateral direction with the connecting part, and configured to press the electric wire toward the connecting part in the closed state, wherein the contact parts are respectively arranged on both left and right sides of the pressing part.

The terminal may include: a fixing part mounted on the terminal fixing part; a lower arm extending forward from below the fixing portion and including the connection portion; an upper arm extending forward from above the fixing portion; and a guide portion which extends rearward from the fixing portion and is mounted on the circuit board, wherein a housing groove into which an end portion of the upper arm is inserted is formed in the housing.

It may be that the actuator further includes: and a shaft portion disposed between the support shafts so as to cover the upper arm, the shaft portion moving rearward from a distal end portion of the upper arm when the actuator is switched from a closed state to an open state.

The upper arm may include: an extension portion extending forward from the fixing portion; and a bending portion which is bent upward and forward from the extending portion and has an extending surface linearly extending from an upper side of the connection portion, wherein the shaft portion moves along the extending surface when the actuator is switched from the closed state to the open state.

When the actuator is rotated to a predetermined angle, the shaft portion may be hooked to the curved portion.

According to another example of the present invention, the contact portion and the connection portion may be arranged alternately in a lateral direction, and the contact portion and the connection portion may be formed to press the electric wire toward the connection portion in the closed state.

According to still another example of the present invention, the contact portion may be inserted into locking grooves formed on both left and right sides of the electric wire and disposed outside the terminal in a state where the actuator is turned off.

The effects of the present invention obtained by the above-described solution are as follows.

First, when the electric wire is inserted into the electric wire housing portion in a state where the actuator is closed, the contact portion located on the lower side of the support shaft is pressed by the electric wire, and a torque acts in a direction in which the actuator is opened. That is, according to the above configuration, in the process of inserting the electric wire into the electric wire housing portion, the actuator which is in the closed state is rotated to be opened, and the electric wire is inserted into the electric wire housing portion, so that the work of connecting the electric wire to the electric connector is more simplified, and the work speed can be increased.

Second, the actuator is configured to be pushed out rearward and rotated within a certain range in the process of inserting the electric wire into the electric wire housing part, and thus it is possible to minimize damage of the terminal part of the electric wire, which may occur due to interference between the terminal and the actuator, in the process of inserting the electric wire into the electric wire housing part.

Fig. 1 and 2 are perspective views of the electrical connector 100 according to an embodiment of the present invention, viewed from different directions from each other, and show a state in which the actuator 130 is closed. Fig. 3 is a perspective view illustrating a state in which the actuator 130 of the electrical connector 100 shown in fig. 1 is opened, and fig. 4 is a perspective view illustrating a state in which the actuator 130 of the electrical connector 100 shown in fig. 2 is opened. Fig. 5 is a top view of the electrical connector 100 shown in fig. 3.

Referring to fig. 1 to 5, the electrical connector 100 is configured to electrically connect a circuit board 1 (see fig. 8) and an electric wire 10 (see fig. 8) to constitute an electric circuit.

In general, in order to configure the above-described circuit, a process of opening the actuator 130 in the closed state by manually rotating the actuator is first performed, but the electrical connector 100 of the present invention has a configuration that does not require the process.

Specifically, when the electric wire 10 is inserted into the electric wire housing 111 in a state where the actuator 130 of the electric connector 100 mounted in the circuit board 1 is closed, the actuator 130 in the closed state is rotated to be opened while the electric wire 10 is inserted into the electric wire housing 111. Thereafter, when the actuator 130 is closed, the terminal portion of the electric wire 10 is fixed in a state of being connected to the connection portion 122a of the terminal 120. Therefore, the work of connecting the electric wire 10 to the electric connector 100 is simplified, and the work speed can be increased.

For reference, the circuit board 1 to which the electrical connector 100 is mounted includes not only the circuit board 1 made of a rigid material but also a flexible circuit board made of a flexible material. In other words, in the present embodiment, the electrical connector 100 is exemplified to be mounted on the rigid circuit board 1, but the present invention is not limited thereto. The electrical connector 100 may be configured to be mounted on a flexible circuit board to electrically connect the electric wire 10 and the flexible circuit board.

Next, the electrical connector 100 capable of simplifying the operation of connecting the electric wire 10 to the electrical connector 100 as described above will be described in more detail.

Fig. 6 is an exploded perspective view of the electrical connector 100 shown in fig. 4, fig. 7 is a front view of the electrical connector 100 shown in fig. 1, and fig. 8 is a schematic view taken along line a-a of fig. 7 to show a process of connecting the electric wire 10 to the electrical connector 100.

Referring to fig. 6-8 and the previous figures together, the electrical connector 100 includes a housing 110, a plurality of terminals 120, and an actuator 130.

The housing 110 constitutes a main body of the electrical connector 100. The housing 110 is formed to extend long in one direction. The housing 110 is made of a non-conductive synthetic resin material for electrically insulating each of the plurality of terminals 120.

The housing 110 is provided with a wire housing 111 that opens forward and a terminal fixing portion 112 that is located behind the wire housing 111.

The wire housing 111 is formed with a space for housing the front end portion of the wire 10. The wire housing 111 is formed to extend long along the extending direction of the housing 110. A guide surface 111a inclined toward the inside may be provided at the front end portion of the wire housing 111 to guide the insertion of the front end portion of the wire 10. For example, the above-described guide surface 111a may be provided to at least one of the upper side and the lower side of the front end portion of the electric wire housing portion 111. In addition, the guide surfaces 111a may be further provided to the front end portion left and right side surfaces of the electric wire accommodation portion 111.

The terminal fixing portion 112 is formed to fix the terminal 120. In the present embodiment, the terminal fixing portion 112 is shown to be formed to be able to fit the terminal 120 inserted from the rear of the housing 110.

The terminal 120 is formed of a conductive metal material, and is mounted and fixed to the terminal fixing portion 112.

The terminal 120 includes a fixing portion 121, a lower arm 122, an upper arm 123, and a guide portion 124.

The fixing portion 121 is attached to the terminal fixing portion 112.

In the present embodiment, it is shown that a groove 121a is provided, the groove 121a being open forward so that the fixing portion 121 is fitted into the terminal fixing portion 112 when the terminal 120 is inserted from the rear of the housing 110, and a fixing projection 121 a' is formed to protrude from an inner side surface that restricts the groove 121 a. The fixing protrusion 121 a' is inserted into the terminal fixing portion 112, so that the terminal 120 is firmly fixed to the terminal fixing portion 112.

The lower arm 122 extends forward from below the fixing portion 121, and includes a connecting portion 122a that is connected to a terminal portion of the electric wire 10.

The through portion 122a protrudes from the bottom surface of the wire housing portion 111, and is formed to be elastically deformable downward by a predetermined pressure. Therefore, a hole 116 or a groove is formed below the connection portion 122a, and a space in which the connection portion 122a can be elastically deformed is provided.

The contact portion 122a includes at least one contact projection 122 a' that contacts a terminal portion of the electric wire 10. In the present embodiment, the engaging portion 122a is shown to include a plurality of engaging projections 122 a' arranged at intervals along the extending direction of the lower arm 122. However, the present invention is not limited thereto. The engaging portion 122a may be provided with a single engaging protrusion 122 a'.

The upper arm 123 extends forward from above the fixing portion 121 and is disposed to face the lower arm 122. The upper arm 123 is configured to support the actuator 130 pressed upward when the actuator 130 is pressed and rotated by the inserted electric wire 10.

The end of the upper arm 123 is inserted into the receiving groove 114 formed in the housing 110. The housing groove 114 is disposed to cover an upper side of an end portion of the upper arm 123, and is configured to prevent the upper arm 123 from being detached by the actuator 130 pressed upward when the actuator 130 is pressed and rotated by the inserted electric wire 10.

The guide portion 124 extends rearward from the fixing portion 121 and is attached to the circuit board 1. In a state where the actuator 130 is closed, the rear end portion of the guide portion 124 may be formed to be more protruded rearward than the actuator 130. In this case, there is an advantage in that the state in which the guide part 124 is assembled in the circuit board 1 is easily checked with the naked eye in the state in which the actuator 130 is closed.

The actuator 130 is formed to be rotatable between a closed state configured to cover the terminal fixing portion 112 and an open state exposing the terminal fixing portion 112. The actuator 130 is formed of a non-conductive synthetic resin material.

The actuator 130 includes an actuator main body 131, a support shaft 132, and a contact portion 133.

The actuator body 131 constitutes a body of the actuator 130. The actuator main body 131 is formed to extend long along the extending direction of the terminal fixing portion 112. A recess 137 may be formed at one side of the actuator body 131. The recessed portion 137 is configured to facilitate insertion of a finger when the actuator 130 is to be lifted in a state where the actuator 130 is closed.

The support shaft 132 is formed to protrude from both left and right sides of the actuator body 131, and is accommodated in support shaft accommodating portions 150 provided on both left and right sides of the terminal fixing portion 112.

The contact portion 133 functions as follows: in the state where the actuator 130 is closed, the contact portion 133 is located lower than the support shaft 132, and in the state where the actuator 130 is closed, the contact portion 133 is pressed by the electric wire 10 inserted into the electric wire housing portion 111 to rotate the actuator 130 to the open state.

Specifically, when the electric wire 10 is inserted into the electric wire housing 111 in a state where the actuator 130 is closed, the contact portion 133 located below the support shaft 132 is pressed by the electric wire 10, and a torque acts in a direction in which the actuator 130 is opened. Therefore, in the process of inserting the electric wire 10 into the electric wire housing 111, the actuator 130 which is closed is rotated to be opened, and the electric wire 10 is inserted into the electric wire housing 111.

The interval from the bottom surface of the wire housing part 111 to the contact part 133 may be formed smaller than the thickness of the leading end part of the wire 10 to enable the above-described mechanism. In this case, even if the electric wire 10 is inserted in contact with the bottom surface of the electric wire housing 111, the leading end portion of the electric wire 10 reaches the contact portion 133, and therefore pressurization of the contact portion 133 and rotation of the actuator 130 by that can be achieved. According to the above mechanism, the work of connecting the electric wire 10 to the electric connector 100 is simplified, and the work speed can be increased.

Referring to fig. 6 and 7, in the present embodiment, the contact portions 133 are formed on both left and right sides of the actuator body 131, respectively, and are disposed outside the terminal 120. In a state where the actuator 130 is closed, at least a part of the contact portion 133 is arranged to laterally overlap the through portion 122 a. Therefore, the pitch from the bottom surface of the wire housing part 111 to the contact part 133 is formed to be smaller than the length by which the contact part 122a protrudes from the bottom surface of the wire housing part 111.

On the other hand, a pressurizing part 134 for pressurizing the electric wire 10 in a state where the actuator 130 is turned off may be further included. The pressing portions 134 and the connecting portions 122a are alternately arranged in the lateral direction, and are formed to press the electric wire 10 toward the connecting portions 122a in a state where the actuator 130 is closed. The pressing portion 134 is disposed so as not to overlap with the connecting portion 122a in the lateral direction.

The contact portions 133 are disposed on both left and right sides of the pressing portion 134, and are formed to protrude downward from the pressing portion 134. In a state where the front end portion of the electric wire 10 is completely inserted into the electric wire housing portion 111, the contact portion 133 is positioned outside the terminal portion of the electric wire 10.

On the other hand, a hooking protrusion 136 hooked to the housing 110 in a state where the actuator 130 is closed may be further included. The hooking protrusion 136 is formed to protrude from both left and right sides of the actuator body 131, and is inserted into the hooking groove 115 of the housing 110 in a state where the actuator 130 is closed, to lock the actuator 130 to the housing 110. Therefore, in the state where the actuator 130 is closed, the actuator 130 can be restricted from being opened by an unexpected external force.

When the contact portion 133 is pressed by the electric wire 10 inserted into the electric wire housing portion 111 in a state where the actuator 130 is closed, the hooking protrusion 136 is separated from the hooking groove 115. That is, the lock of the actuator 130 is released, and the actuator 130 is rotated to the open state.

Next, a configuration capable of minimizing damage to the terminal portion of the electric wire 10 in such a process of connecting the electric wire 10 to the electric connector 100 is explained.

Fig. 9 is a schematic view for explaining a mechanism of retracting the actuator 130 in the process of inserting the electric wire 10 into the housing, taken along line B-B of fig. 4.

Referring to fig. 9 together with the foregoing fig. 8, the actuator 130 is configured to be pushed out rearward within a certain range and rotated in the process of inserting the electric wire 10 into the electric wire housing 111. That is, when the actuator 130 is switched from the closed state to the open state, the actuator 130 is formed to move relative to the communication portion 122 a. Therefore, it is possible to minimize the damage of the terminal portion of the electric wire 10, which may occur due to the interference between the terminal 120 and the actuator 130, in the process of inserting the electric wire 10 into the electric wire accommodation portion 111.

Therefore, the support shaft accommodating portion 150 that accommodates the support shaft 132 is formed to extend in the front-rear direction of the housing 110, and when the actuator 130 is switched from the closed state to the open state, the support shaft 132 moves from the front side of the support shaft accommodating portion 150 to the rear side.

In the present embodiment, a configuration is shown in which the support shaft accommodating portion 150 is restricted by the hook 140 and the housing 110.

The hook 140 is mounted on the hook fixing portion 113 formed at both sides of the case 110, and is formed to be fixed to the circuit board 1 to firmly fix the case 110 to the circuit board 1. The hook 140 may be formed of a metal material and mounted to the circuit board 1.

The hook 140 includes a hook body 141 and an extension arm 142.

The hook body 141 is inserted into the hook fixing portion 113. In the present embodiment, a structure in which the hook 140 is inserted and fitted into the hook fixing portion 113 opened forward is shown.

The extension arm 142 is configured to cover the support shaft 132 extending from the hook body 141 within the support shaft accommodating portion 150. The end of the extension arm 142 may be inserted into the fixing groove 117 of the housing 110. A portion of the extension arm 142 is exposed to the upper side of the housing 110.

According to the configuration, the hook 140 and the case 110 form the support shaft accommodating part 150 in a closed loop form. The support shaft accommodating portion 150 extends in the front-rear direction of the housing 110.

Referring to fig. 8, the actuator 130 may further include a shaft portion 135 disposed between the pressurization portions 134. In arrangement, the shaft portion 135 is disposed between the support shafts 132 formed to protrude from both left and right sides of the actuator main body 131. The central axis of the shaft 135 coincides with the central axis of the support shaft 132. The shaft portion 135 is configured to be covered by the upper arm 123.

The shaft 135 is formed to move rearward from the front end of the upper arm 123 in the process that the actuator 130 in the closed state is pushed rearward and rotated to the open state by the wire 10 inserted into the wire housing 111 pressing the contact portion 133.

The upper arm 123 includes an extension 123a and a bent portion 123b to implement the above-described mechanism.

The extending portion 123a extends forward from the fixing portion 121.

The bent portion 123b is bent upward from the extending portion 123a, and then bent forward to extend forward. The bent portion 123b has an extended surface linearly extending toward the upper side of the connection portion 122 a.

In the process that the actuator 130 in the closed state is pushed out rearward and rotated to the open state by the contact portion 133 being pressed by the electric wire 10 inserted into the electric wire housing portion 111, the shaft portion 135 is formed to move rearward along the extending surface. When the actuator 130 is rotated to a predetermined angle, the shaft 135 may be formed to be hooked on the bent portion 123 b. That is, the shaft portion 135 is hooked to the bent portion 123b, so that the rotation angle of the actuator 130 can be regulated.

Next, another embodiment in which the contact portion 133 is formed at another position will be described.

Fig. 10 is a front view of an electrical connector 200 according to another embodiment of the present invention.

Referring to fig. 10, the contact portions 233 and the through portions 222a are alternately arranged in the lateral direction, and the actuator 230 is formed to press the electric wire 10 toward the through portions 222a in the closed state. That is, the contact portion 233 in the present embodiment can be understood as a structure corresponding to the pressing portion 134 of the embodiment described with reference to fig. 1 to 9.

However, in the foregoing embodiment, the interval from the bottom surface of the electric wire housing part 111 to the pressing part 134 is formed to be larger than the thickness of the leading end part of the electric wire 10, and when the electric wire 10 is inserted while being kept in contact with the bottom surface of the electric wire housing part 111, it is constituted so that the leading end part of the electric wire 10 does not reach the contact part 133.

However, in the present embodiment, the distance from the bottom surface of the wire housing 211 to the contact portion 233 is formed to be smaller than the thickness of the tip end portion of the wire 10, and when the wire 10 is inserted while being held in contact with the bottom surface of the wire housing 211, the tip end portion of the wire 10 reaches the contact portion 233, and pressurization of the contact portion 233 and thus rotation of the actuator 230 are configured to be achieved.

In a state where the actuator 230 is closed, at least a part of the contact portion 233 is arranged to overlap laterally with the through portion 222 a. Therefore, the pitch from the bottom surface of the wire housing 211 to the contact portion 233 is formed to be smaller than the length by which the contact portion 222a protrudes from the bottom surface of the wire housing 211.

Fig. 11 is a front view of an electrical connector 300 according to still another embodiment of the present invention, and fig. 12 is a schematic view taken along line C-C of fig. 11 to show a process of connecting an electric wire 10 to the electrical connector 300.

Referring to fig. 11 and 12, the contact portions 333 are formed on both left and right sides of the body 331 and are disposed outside the terminal 320. The contact part 333 is arranged to protrude downward in a state where the actuator 330 is closed.

In a state where the actuator 330 is closed after the electric wire 10 is completely inserted into the electric wire receiving part 311, the contact part 333 is inserted into the locking grooves 10a formed at both left and right sides of the electric wire 10. Thus, even if the electric wire 10 receives a force in the direction of being drawn out from the electric wire housing 311, the locking groove 10a is hooked on the contact part 333, and the drawing-out of the electric wire 10 is restricted.

In a state where the actuator 330 is closed, at least a part of the contact part 333 is arranged to laterally overlap the through part 322 a. In the present embodiment, it is shown that the distance from the bottom surface of the electric wire housing part 311 to the contact part 333 is formed to be smaller than the length by which the contact part 322a protrudes from the bottom surface of the electric wire housing part 311. However, the present invention is not limited thereto. The contact portion 333 may be inserted into a groove (not shown) formed in the bottom surface of the wire housing portion 311.
