The present embodiment discloses an electrical connector assembly 100, the electrical connector assembly 100 includes a first terminal electrical connector 1A and a second terminal electrical connector 1B disposed correspondingly to each other, and the electrical connection is formed by the combination of the first terminal electrical connector 1A and the second terminal electrical connector 1B.

The first terminal electrical connector 1A mainly includes a first terminal member 10 and a rotating cap 20 disposed on the first terminal member 10. The terminal 10 includes a first terminal body 11, one or more electrical terminals 12 disposed inside the first terminal body 11, and a torsion spring 13 positioned on the first terminal body 11. The first terminal body 11 has a limiting groove 14 for limiting the pivoting stroke and a first positioning groove 15 for positioning the first end 131 of the torsion spring 13, and a boss 141 is disposed on one side of the limiting groove 14. The rotating cap 20 includes a cap body 21 and one or more locking blocks 22 disposed on the cap body 21 for locking to the second terminal electrical connector 1B. The cap body 21 has a slider 211 and a second positioning groove 212 formed on an inner peripheral surface thereof. The sliding block 211 is correspondingly disposed in the limiting groove 14 to limit the pivoting stroke of the rotating cap 20 relative to the first terminal body 11. The second end 132 of the torsion spring 13 is disposed inside the second positioning groove 212 to inertially restore the rotary cap 20 to a position of a reset angle relative to the first terminal body 11. In one embodiment, the locking block 22 is provided with a first guiding inclined surface 221.

In one embodiment, the second positioning groove 212 includes a guiding groove 2121 extending to an opening of one side of the rotary cap 20 for guiding the second end 132 of the torsion spring 13, and a limiting groove 2122 disposed at an inner end of the guiding groove 2121, wherein two sides of the limiting groove 2122 are respectively provided with a limiting wall 2123, and the design of the limiting wall 2123 prevents the second end 132 of the torsion spring 13 from escaping from the limiting groove 2122.

In one embodiment, in order to enhance the bonding strength between the rotating cap 20 and the first terminal member 10 in the inserting/extracting axial direction, one or more positioning wings 23 are disposed on the inner circumferential surface of the rotating cap 20, and one or more lateral locking portions 16 disposed to match the positioning wings 23 are disposed on the outer circumferential side of the first terminal member 10. The side locking portion 16 includes a first thrust wall 161, a second thrust wall 162, and a fitting groove 163 provided between the first thrust wall 161 and the second thrust wall 162. The engaging groove 163 is configured to be engaged by the positioning wing 23 when the sliding block 211 is locked to the limiting groove 14, so as to limit the axial stroke of the rotating cap 20 relative to the first terminal 10. In one embodiment, in order to allow the positioning wing 23 to evade the first thrust wall 161 when the rotation cap 20 and the first terminal member 10 are axially combined, so that the positioning wing 23 is aligned to the opening OP between the first thrust wall 161 and the second thrust wall 162, the first thrust wall 161 is shorter than the second thrust wall 162 to form an escape space SP for the positioning wing 23 to enter the engaging groove 163.

The second terminal electrical connector 1B is configured to be electrically connected to the first terminal electrical connector 1A. The second terminal electrical connector 1B includes a second terminal body 30 and one or more electrical terminals 31 disposed inside the second terminal body 30. The outer peripheral surface of the second terminal body 30 is provided with locking grooves 32 corresponding to the number and positions of the locking blocks 22, so that the locking blocks 22 can be locked and combined after being guided. The locking block 22 on the rotation cap 20 is inserted and locked to the locking groove 32 by the inertial force of the torsion spring 13 to limit the axial stroke between the first terminal electrical connector 1A and the second terminal electrical connector 1B.

The second terminal body 30 of the second terminal electrical connector 1B is abutted with the first terminal body 11 of the first terminal electrical connector 1A, so that the terminal pins (electrical terminals 12) inside the first terminal body 11 are inserted into the terminal slots (electrical terminals 31) inside the second terminal body 30 to form electrical connection.

In an embodiment, the first terminal body 11 of the first terminal electrical connector 1A is provided with a first position-limiting portion 112 (as shown in fig. 7), and the second terminal body 30 of the second terminal electrical connector 1B is provided with a second position-limiting portion 33 corresponding to the first position-limiting portion 112. In the present embodiment, the first position-limiting portion 112 is a fool-proof rib, and the second position-limiting portion 33 is a fool-proof groove; in another embodiment, the first position-limiting portion 112 is a fool-proof groove, the second position-limiting portion 33 is a fool-proof rib, and the first position-limiting portion 112 and the second position-limiting portion 33 can be implemented in any form to achieve the effect of interference positioning, and the variations of the forms are not limited in the present invention. In another embodiment, the first position-limiting portion 112 and the second position-limiting portion 33 can be omitted according to the practical situation, and are not limited in the present invention.

In order to combine the first terminal body 11 and the second terminal body 30, the locking block 22 of the rotating cap 20 is locked in the locking groove 32 by the inertia force of the torsion spring 13, so as to achieve the effect of preventing unlocking, the locking groove 32 includes an opening 321 disposed on the outer peripheral surface, and a locking groove 322 disposed on the outer peripheral surface and communicated with the opening 321, and a second guiding inclined plane 323 is disposed on one side of the opening 321 of the locking groove 32, and the second guiding inclined plane 323 inclines from outside to inside in the direction of the opening 321. Wherein the distance between the locking grooves 322 of the opening 321 is within the range of the rotation distance of the rotating cap 20 relative to the first terminal 10 (corresponding to the arc range of the limiting groove 14). Under the condition that the first position-limiting portion 112 and the second position-limiting portion 33 are aligned, when the locking block 22 is aligned to the opening 321, the sliding block 211 is located at a first position in the position-limiting groove 14 corresponding to the tightening of the torsion spring 13; under the condition that the first position-limiting portion 112 and the second position-limiting portion 33 are aligned, when the locking block 22 is aligned to the locking groove 322, the sliding block 211 is located at a second position where the position-limiting groove 14 is released corresponding to the torsion spring 13 relative to the first position. With the foregoing arrangement, the inertial force of the torsion spring 13 provides a torsional force from the opening 321 toward the groove 322 to rotate the rotation cap 20 to lock the locking block 22 inside the groove 322.

In one embodiment, the second terminal body 30 has threads 34 on its outer periphery for locking with internal threads (not shown) of a protective housing, but not limited thereto.

The specific structure of the electrical connector assembly 100 of the present invention is described in detail above, and the following description is directed to the usage status of the electrical connector assembly 100 of the present invention, please refer to fig. 5 and fig. 6, which are a combination diagram (a) of the male and female terminals according to the first embodiment of the present invention and a combination diagram (b) of the male and female terminals according to the first embodiment of the present invention, as shown in the drawings.

First, as shown in fig. 5, in the assembly stage of the male and female terminals, the first position-limiting portion 112 (e.g., a fool-proof rib) of the first terminal body 11 is aligned to the second position-limiting portion 33 (e.g., a fool-proof groove) of the second terminal body 30 (as shown in fig. 2 and 7), so as to axially combine the first terminal body 11 and the second terminal body 30. The rotating cap 20 is configured such that when the first position-limiting portion 112 is aligned to the second position-limiting portion 33, the first guiding inclined surface 221 of the locking block 22 of the rotating cap 20 is aligned to the second guiding inclined surface 323 of the locking groove 32.

Subsequently, as shown in fig. 6, when the first terminal body 11 is inserted into the second terminal body 30, the first guiding inclined surface 221 on the locking block 22 of the rotating cap 20 is urged toward the second guiding inclined surface 323 and moves toward the opening 321 (urging the torsion spring 13) along with the guiding of the second guiding inclined surface 323; when the locking block 22 enters the opening 321, the locking block 22 moves to the releasing side of the torsion spring 13, and the elastic force provided by the torsion spring 13 is received and moves toward the card slot 322 through the position of the opening 321 (as shown by arrow a1), so as to achieve the locking effect.

When the lock is removed, the rotating cap 20 is rotated reversely (in the unlocking direction) to the bottom, and the first terminal body 11 is pulled out backward, so that the unlocking effect can be achieved. The unlocked spin cap 20 is returned to the initial position by the elastic force of the torsion spring 13.

Referring to fig. 7 to 12, the assembly process of the first terminal electrical connector 1A is shown from the first embodiment of the present invention (i) to (vi).

For convenience of explanation and clear understanding of the technical features of the present invention, the rotating cap in the assembly process of fig. 7 to 12 only shows a part of the inner structure of the rotating cap in the drawings, respectively, so as to clearly understand the assembly procedure of the present invention.

Referring to fig. 7, in the assembling process, the central engaging portion of the torsion spring 13 is first engaged with the outer periphery of the first terminal body 11, and the first end 131 of the torsion spring 13 is inserted into the positioning slot 15 to couple the torsion spring 13 to the first terminal body 11.

Next, the second end 132 of the torsion spring 13 is aligned with and inserted into the opening of the guiding groove 2121 of the rotating cap 20, and then the rotating cap 20 is sleeved on the first terminal body 11 as shown in fig. 8, so that the second end 132 of the torsion spring 13 moves along the guiding groove 2121 and is pushed to the bottom by the axial direction (as arrow direction a2) until the locking block 22 contacts the first thrust wall 161.

Next, referring to fig. 9, the rotating cap 20 is rotated relative to the first terminal member body 11, and the locking block 22 is aligned to pass through the passing groove 17 between the adjacent lateral locking portions 16, and then, as shown in fig. 10, the rotating cap 20 is pushed forward to the bottom in the axial direction (as shown by arrow a3) until the positioning wing 23 passes through the escape space SP and hits the second thrust wall 162.

Referring to fig. 11, after the above assembling process, the position of the sliding block 211 is configured to be aligned to the boss 141 on one side of the limiting groove 14; then, as shown in fig. 12, for example, the rotating cap 20 is rotated to make the sliding block 211 pass through the boss 141 (as shown by arrow a4), so that the sliding block 211 moves into the limiting groove 14; at the same time, the positioning wing 23 is inserted into the fitting groove 163 between the first thrust wall 161 and the second thrust wall 162, so that the axial locking is formed.

In addition to the above embodiments, the same structure can be implemented in the case of the exchange between the male and female terminals, please refer to fig. 13 and 14, and the appearance diagram (a) and the appearance diagram (b) of the second embodiment of the present invention.

In the second embodiment of the present invention, the first terminal electrical connector 1C can be implemented in the form of a male terminal, and the second terminal electrical connector 1D can be implemented in the form of a female terminal in cooperation with the first terminal electrical connector 1C. Specifically, the first terminal electrical connector 1C includes a rotating cap 20A and a first terminal 10A disposed in cooperation with the rotating cap 20A, wherein the internal structure of the rotating cap 20A is substantially the same as that of the first embodiment, and is not described again. Compared with the first embodiment, the electrical terminal 12A on the first terminal body 11A of the present embodiment is implemented in the form of a terminal slot instead of a terminal pin, and in the form of a convex column to form a male terminal; the second terminal electrical connector 1D includes a second terminal member body 30A, wherein the outer configuration of the peripheral side of the second terminal member body 30A is substantially the same as that of the first embodiment. Compared with the first embodiment, the electrical terminal 31A of the second terminal body 30A of the present embodiment is a terminal pin instead of a terminal slot, and the female terminal is formed by a slot into which a stud is inserted. The reverse arrangement of the male and female terminals, and the difference in the number, shape and size of the terminal pins and the terminal slots are not intended to limit the scope of the present invention. In another embodiment, the present invention can also be used in various conventional connectors, which are not limited in the present invention.

In summary, the terminal electrical connector of the present invention not only can achieve the effect of quick detachment and quick assembly, but also can achieve relatively high strength in connection in the plugging and unplugging axial direction, and has high convenience and reliability. In addition, in a secondary effect, the terminal electric connector of the invention is easier in assembly procedure compared with the traditional electric connector, thereby effectively increasing the efficiency of the manufacturing process and reducing the cost.

The present invention has been described in detail, but the above description is only a preferred embodiment of the present invention, and the scope of the present invention should not be limited thereby, and all equivalent changes and modifications made according to the claims of the present invention should still fall within the scope of the present invention.
