Technical Field

The invention relates to the technical field of electrical devices, in particular to an electrical connector and an LED lamp thereof.

Background

In the conventional electrical connector, generally, the shell of the terminal is opened, the external conductor is fixedly connected with the conductive element in the terminal by using the connecting piece or the fixing piece, and then the shell is closed to connect the conductor to the connector.

In order to avoid the above problems, the electrical connectors that are currently marketed achieve a quick-insertion connection between conductors that are mated to different terminals by detachably engaging male and female terminals with each other. The butt joint mode between the conductors is simplified, and the conductor splicing operation is more convenient. However, the applicant has found that with a male-female butt type connection, which is convenient, the fitting of the internal conductive element is more cumbersome, which makes the assembly of the conductive element inconvenient and reduces the wire clamping effect to a great extent. The contact tightness of the conductive element in the terminal is poor, so that the electric connection is unstable and the reliability is poor. In addition, the loose phenomenon of the installation and the positioning of the conductive element in the terminal is inevitably easy to occur, and the connection operation of the conductor and the terminal is directly influenced.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention.

Examples

With reference to fig. 1 to 5, the present embodiment provides an electrical connector including a male terminal 1 and a female terminal 2, wherein the male terminal 1 and the female terminal 2 are electrically connected together in a detachable manner. The male terminal 1 includes a first electrical connector 11, a first elastic member 12, a first wire opening 13 and a first connection opening 14. The first elastic element 12 is able to exert pressure on the wire to bring the conductor of the wire into abutment against the first electrical connector 11. The first elastic member 12 and the wire pass through the first wire opening 13 and are mounted in the male terminal 1, and the first electric connector 11 passes through the first connection opening 14 and is mounted in the male terminal 1 to electrically connect the first electric connector 11 with the conductor.

In the above embodiment, the first wire opening 13 is defined on one of the outer end sides of the male terminal 1 to allow an external conductor to be clamped into the conductive member of the male terminal 1, thereby facilitating further electrical connection to the female terminal 2, and further electrical connection to the conductor externally connected to the female terminal 2 side. A first connection opening 14 disposed opposite the first wire opening 13 is defined at the other outer end side of the male terminal 1, and is detachably joined to the female terminal 2 through the first connection opening 14. It is particularly important that the first electrical connector 11 and the first elastic member 12 are separated from each other, such that the first elastic member 12 is configured to pass through the first wire opening 13 and be installed and limited in the terminal, the first electrical connector 11 is configured to pass through the first opening and be stably installed in an installation position in the terminal, and a clamping opening capable of elastically clamping a conductor is defined between the first elastic member 12 and the first electrical connector 11. Therefore, the elastic force in the clamping direction is provided to the conductor by the first elastic member 12, so that the conductor is stably and closely contacted on the first electric connecting member 11, and the electric connection is realized.

This arrangement ensures that the two conductive elements in the male terminal 1 are arranged in a detachable manner in horizontally different directions, so that the manner of assembly of the first electrical connector 11 can be highly adapted to the insertion and extraction operations of the conductors in the terminal. Specifically, when the conductor is inserted into the first wire opening 13 side, the first electrical connector 11 receives a pushing force in the insertion direction, and is more easily mechanically and electrically contact-fitted with the conductive member in the female terminal 2. And, when the conductor is pulled out at the first wire opening 13 side, the first electric connector 11 is subjected to a pulling force in a pulling direction which coincides with the assembling direction of the first electric connector 11, so that the first electric connector 11 is further mounted in place so as to be stably confined in the mounted position, the movement of the first electric connector 11 can be effectively prevented from being disengaged, and the formed jaw elastic force is kept stable correspondingly.

One embodiment of the conductor is an electric wire with an end portion stripped with an insulating layer. And the conductive element of the male terminal 1 can be, but is not limited to, components such as an electrical connector and an elastic element.

The first wire opening 13 and the first connecting opening 14 are engaged with each other through the first mounting cavity 15 and the second mounting cavity 16, so as to form a plug space in the male terminal 1 for facilitating the entry of the conductor along the wire opening.

Wherein, a partition 17 is arranged between the first mounting cavity 15 and the second mounting cavity 16, and the partition 17 is configured in the male terminal 1 to define two different mounting cavities for assembling and adapting the power connector and the elastic element.

Specifically, a first clamping protrusion 151 and a limiting groove 152 for installing two side edges of the first electrical connector are arranged at the lower part in the first installation cavity 15, and the first electrical connector 11 is provided with a hollow 113 matched with the first clamping protrusion 151 and a step 114 matched with the partition board 17. Therefore, the first electrical connector 11 enters along the first connection opening 14 until being assembled and limited at the installation position, on one hand, the electrical connector is ensured to be installed in place in the male terminal 1 through the clamping matching of the hollow opening 113 and the first clamping protrusion 151, on the other hand, the partition plate 17 and the step 114 correspondingly arranged on the electrical connector are matched in place, so that accurate installation alignment is achieved together, and the assembly effect is particularly remarkable. The second mounting cavity 16 is communicated with the first mounting cavity 15 through a through hole formed in the partition 17, so that the first electrical connector 11 is allowed to enter the first mounting cavity 15 along the through hole, and the step 114 of the first electrical connector is accurately abutted with the through hole.

And, the upper portion in the first installation cavity 15 is provided with an installation groove 154 for installing two side edges of the first elastic member 12 and a second clamping protrusion 153 for limiting the first elastic member 12 at the installation position, and the second clamping protrusion 153 cooperates with the first elastic member 12 to prevent the first elastic member 12 from being separated towards the first lead opening 13. The specific matching manner of the second clamping protrusion 153 and the first elastic member 12 is, as shown in fig. 4 and 5, that the male terminal 1 is formed with a second clamping protrusion 153 on the inner wall of the first mounting cavity 15, and the first elastic member 12 is provided with a support arm 1232 matched with the second clamping protrusion 153. Wherein, support arm 1232 disposes on the terminal surface of first elastic component 12 one side protruding towards the joint with shell fragment form slope, and support arm 1232's incline direction sets to the installation direction of following first elastic component 12 and is outstanding outwards to do benefit to smooth-going buckle to the joint protruding, and make support arm 1232 and joint after the block can form spacing cooperation between protruding, prevent that its elastic component takes place to run the position phenomenon at plug conductor in-process.

In the above, any of the snap projections is configured as an inclined body with a guide ramp surface, and the guide ramp surface is configured gently inclined towards the direction facilitating the electrical connector/spring to be fitted in place for quick assembly.

As shown in fig. 4 and 5, at least one side edge of the first elastic member 12 is provided with a clamping portion 1231, and the clamping portion 1231 is clamped with the mounting groove 154 to generate movement resistance. Thus, the first elastic member 12 is assembled into the first mounting cavity 15 along the assembling direction, and is embedded with the mounting groove 154 through the clamping portion 1231 thereof to be in sliding fit until the first elastic member 12 is mounted in place.

Specifically, the mounting groove 154 is provided with a stop portion, and the stop portion is engaged with an end portion of the first elastic member 12. The stop portion is formed at the inner end of the mounting groove 154, and the first elastic member 12 is movable to the clamping portion 1231 thereof to be clamped and matched with the stop portion, so as to be stably limited in the first mounting cavity 15.

In one embodiment, the left and right sides of the first elastic member 12 are both provided with the clamping portions 1231, the mounting grooves 154 are correspondingly disposed on both sides of the first mounting cavity 15, and the outer ends of the mounting grooves 154 penetrate through to the outside of the first wire opening 13, so as to facilitate the quick assembly of the first elastic member 12 into the first mounting cavity 15 along the first wire opening 13.

As shown in fig. 3 and 11, further, the first elastic element 12 includes an elastic arm 121 and a limiting arm 122 for limiting the deformation degree of the elastic arm 121, and the elastic arm 121 applies pressure to the wire to make the conductor of the wire tightly contact with the first electrical connector 11. Specifically, the first elastic element 12 is formed in a triangular shape with a notch 124 and is bent integrally, the elastic arm 121 and the position-limiting arm 122 are connected by a connecting arm 123, and the notch 124 is formed by the inner end side of the elastic arm 121 and the position-limiting arm 122 facing each other, so as to allow the elastic arm 121 to perform elastic deformation only in the path of the notch 124, thereby preventing the elastic arm 121 from elastic failure. The outer end side of the elastic arm 121 faces the first electrical connector 11 to form the nip, and the elastic arm 121 is obliquely abutted against the connecting arm 123 and is supported and fitted by the connecting arm 123 with the elastic force of the elastic arm 121. In addition, the first elastic part 12 in a triangular shape is arranged on one side of the first installation cavity 15, the first electrical connector 11 in a strip shape is oppositely arranged on the other side of the first installation cavity 15, so that a clamping opening with elastic force is formed in a matched mode, the external conductors are respectively clamped between two independent elements, and the elastic clamping effect is particularly remarkable.

In one embodiment, the latching portions 1231 are disposed on both right and left sides of the connecting arm 123, and the arms 1232 are protrudingly disposed on the outer end side of the connecting arm 123. And the connecting arm 123 is bearing-disposed in the first mounting cavity 15 to provide a smooth, effective resilient support for the resilient arm 121.

In one embodiment, the male terminal 1 is provided with a plurality of wire openings and connecting openings matching with the wire openings side by side, and the female terminal 2 is configured in the same manner as the male terminal 1 so as to facilitate the male-female plug-in mating.

As also shown in fig. 6 to 8, correspondingly, the female terminal 2 comprises a second electrical connector 21, a second elastic member 22, a second wire opening 23 and a second connection opening 24. The second elastic element 22 is able to exert pressure on the wire to press the conductor of the wire against the second electrical connection 21. The second elastic member 22 and the wire pass through the second wire opening 23 and are mounted in the female terminal 2, and the second electric connector 21 passes through the second connection opening 24 and is mounted in the female terminal 2 to electrically connect the second electric connector 21 with the conductor.

In the above, by the second elastic member 22 being fitted into the female terminal through the second wire opening 23, the second electric connector 21 is fixedly fitted into the female terminal 2 through the second connection opening 24 to prevent the second electric connector 21 from being detached from the fitting position when receiving a pulling force toward the second wire opening 23. In addition, for the structural configuration, the working principle and the implementation manner of the conductive element in the female terminal 2, reference may be made to the related contents of the first electrical connector 11 and the first elastic member 12 of the male terminal 1, which are not described herein again. The elastic clamping fit between the electrical connector and the elastic element of the female terminal 2 in the installation cavity and the installation limit thereof are substantially the same as the specific configurations of the electrical connector and the elastic element of the male terminal 1.

As shown in fig. 1 and 9, it is particularly critical that the male terminal 1 and the female terminal 2 are capable of fitting when the two terminals are engaged. The male terminal 1 is disposed at the first connection opening 14 side and the outer housing thereof is configured to be snap-fitted into the second connection opening 24 of the female terminal 2, thereby forming a male-female connection type detachable fit.

As shown in fig. 10, the first electrical connector 11 includes an electrical connection section 111 connected to the conductor and a mating section 112 electrically connected to the second electrical connector 21 of the female terminal 2. The electrical connection section 111 is tightly attached to the bottom surface of the first mounting cavity 15, and the mating section 112 is tightly attached to the bottom surface of the second mounting cavity 16. Therefore, the electric connector is stably supported inside the male terminal 1, and more stable electric connection is achieved.

After the two terminals are assembled, the conductive elements in the terminals are contacted to realize electrical connection. Specifically, the second electrical connector 21 of the female terminal 2 and the first electrical connector 11 of the male terminal 1 are in end-to-end mating for assembly and disassembly. The second electrical connector 21 is a plate, and one end of the second electrical connector is bent and extends downward to form a fork-shaped structure 212 with elasticity, the mating section 112 of the first electrical connector 11 is configured to extend upward to form a clasping structure, and after the terminals are jointed, the fork-shaped structure 212 is elastically clamped and arranged in the clasping structure, so that the two electrical connectors are tightly clamped, and are mechanically and electrically butted together.

Particularly, the insertion matching mode formed by bending and sinking one end part of the electric connecting piece can be self-adaptive to mutual butt joint between the two electric connecting pieces, so that the electric connecting pieces are more flexible in the installation positions of the terminals of the electric connecting pieces, the floating range for allowing the two end parts to be effectively jointed is larger, and the operability of quick connection and quick disconnection of the electric connecting pieces is remarkably improved.

The present embodiment further provides an LED lamp. The LED lamp comprises a lamp body and the electric connector. The assembling and configuring mode of the elastic piece and the electric connecting piece in the male terminal 1 and the female terminal 2 of the electric connector is obviously matched with a plug wire in an LED lamp for use, and the electric connection mode between the elastic piece and the electric connecting piece is better, stable and efficient.

The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions belonging to the idea of the present invention belong to the protection scope of the present invention.
