Description

Technical Field

[0001] The present invention relates to a connector technology, and particularly to a connector that is easy to assemble. Background Art

[0002] Connectors are mainly used to provide electrical connections for different power cords. The connector includes an insulating housing and several conductive terminals inserted inside the insulating housing. The power cord includes several core wires, and each core wire is respectively connected to each conductive terminal.

[0003] The current combination methods of power cords and connectors are roughly in the following several forms. One is to weld the core wires and the conductive terminals together, and then insert each conductive terminal into each terminal receiving groove of the insulating housing one by one. Another is to insert the conductive terminals into each terminal receiving groove of the insulating housing, and then connect each core wire to each conductive terminal.

[0004] However, in the foregoing various combination methods, since the insulating housing is of an integral design, the assembly of each conductive terminal and the insulating housing becomes quite cumbersome, time-consuming and inconvenient, and the stability after assembly is not ideal, which does not meet the economic benefits at all. Under the increasingly miniaturized design of the connector, the interval between each terminal receiving groove will be greatly shortened, which further increases the difficulty of assembling it with each conductive terminal. Moreover, most of the components of such connectors can only be used once, thus causing waste of limited resources.

[0005] In view of this, in view of the above-mentioned deficiencies of the prior art, the inventor of the present invention has specifically studied intensively and combined with the application of theory to try his best to solve the above-mentioned problems, which has become the goal of the inventor's improvement. Summary of the Invention

[0006] An object of the present invention is to provide a connector that is easy to assemble, which can simplify the assembly process and shorten the assembly time by separately providing an insulating base and a rubber core.

[0007] To achieve the above object, the present invention provides a connector that is easy to assemble, including an insulating base, a rubber core and several conductive terminals. The insulating base has a cavity; the rubber core is disposed corresponding to the cavity. The rubber core is provided with a guiding hole and several concave grooves formed around the guiding hole and communicating with the guiding hole. Each concave groove forms a terminal receiving groove; each conductive terminal is respectively installed corresponding to each terminal receiving groove.

[0008] A guiding column extends from the center of the cavity, the guiding hole is sleeved corresponding to the guiding column, and the terminal receiving groove is surrounded by the concave groove and the guiding column.

[0009] In some embodiments, the guide column includes a longitudinal rod and a transverse rod intersecting the longitudinal rod, and a concave arc surface is formed between any two adjacent transverse rods and the longitudinal rods, and each of the concave grooves and each of the concave arc surfaces jointly enclose each of the terminal receiving grooves.

[0010] In some embodiments, a guide channel is respectively provided on the end surface of the transverse rod and the longitudinal rod, and a fillet is formed between any two adjacent grooves, and each fillet is respectively engaged with each guide channel.

[0011] In some embodiments, a through hole penetrating through the insulating base is formed at the root of each of the concave arc surfaces, and each of the conductive terminals includes a conductive section extending through the through hole.

[0012] In some embodiments, one side of the insulating base has an annular wall, the cavity is formed inside the annular wall, a positioning strip is formed on the inner edge of the annular wall, and a positioning groove is provided on the peripheral wall of the rubber core for the positioning strip to be embedded and positioned.

[0013] In some embodiments, a clamping hole and a clamping groove are respectively provided at two corresponding positions of the ring wall, and an elastic arm is respectively provided at two corresponding positions of the rubber core. Each elastic arm is formed with a handle and a clamping block. The clamping block is clamped corresponding to the clamping hole, and the handle is engaged with the clamping groove.

[0014] In some embodiments, each of the conductive terminals includes a connecting section, a fixed section extending from the connecting section, and a conductive section extending from the fixed section. Each of the fixed sections has a stop ring. A stop ring is formed inside each of the grooves, and the stop ring is stopped by the stop ring.

[0015] In some embodiments, a neck portion is provided below the stop ring, and an elastic hook is provided at the bottom end of the stop ring. A clearance space is formed between the back of the elastic hook and the wall of the cavity, and the elastic hook is buckled against the neck portion.

[0016] In some embodiments, the connecting section is provided with a core wire insertion hole for plugging and connecting a core wire of an electric wire.

[0017] In some embodiments, the easily assembled connector further comprises a sleeve and a threaded connector, wherein the sleeve is sleeved on one side of the insulating base, and the threaded connector is connected to one end of the sleeve and surrounds the outer circumference of the insulating base.

[0018] The present invention also has the following effects. Through the sliding connection of the guiding posts and guiding holes, it is easy to install the rubber core and each conductive terminal together into the insulating base for combination. By means of the arrangement of each elastic arm, when the rubber core reaches the predetermined position, each clamping block can be correspondingly clamped and positioned in each clamping hole. After pressing the lever of each elastic arm, each clamping block can be disengaged from the holding of each clamping hole, and then the rubber core and each conductive terminal can be taken out of the insulating base together. It is not only easy to take out but also each component can be reused. With the embedding and cooperation of each strip and each guiding channel, each conductive terminal can be accurately aligned with the terminal receiving groove for insertion. Through the separate design of the insulating base and the rubber core, the production and processing of each component become easier. Brief Description of the Drawings

[0069] The detailed description and technical content of the present invention are described below in conjunction with the accompanying drawings. However, the accompanying drawings are only provided for reference and illustration, and are not used to limit the present invention.

[0070] Please refer to Figures 1 to 8 As shown, the present invention provides an easily assembled connector, which mainly includes an insulating base 10, a rubber core 20 and several conductive terminals 30.

[0071] Please refer to Figure 4 and Figure 5 As shown, the insulating base 10 is made of insulating plastic materials such as plastics, and is generally in a cylindrical shape. On one side of the insulating base 10, there is an annular wall 11. An accommodating cavity 12 is formed inside the annular wall 11, and a guiding column 13 extends in the center of the accommodating cavity 12. In addition, a positioning strip 111 is formed on the inner edge of the annular wall 11; a clamping hole 112 and a clamping groove 113 are respectively provided at two corresponding positions of the annular wall 11.

[0072] Furthermore, the guiding column 13 is generally in a cross shape, mainly including a longitudinal rod 131 and a transverse rod 132 intersecting with the longitudinal rod 131. A guiding channel 133 is respectively provided on the end faces of the transverse rod 132 and the longitudinal rod 131. A concave arc surface 134 is respectively formed between the ends of any two adjacent transverse rods 132 and longitudinal rods 131, and each concave arc surface 134 is in a stepped shape. A through hole 14 penetrating the insulating base 10 is opened at the root of each concave arc surface 134.

[0073] Continue to refer to Figures 1 to 3 As shown, the rubber core 20 is also made of insulating plastic materials and is a hollow cylindrical body. It is assembled corresponding to the accommodating cavity 12. A guiding hole 21 is provided at the center position of the rubber core 20. Several concave grooves 22 are respectively provided in the area around the guiding hole 21 and communicating with the guiding hole 21. The guiding hole 21 is sleeved corresponding to the guiding column 13, and a terminal receiving groove A is surrounded between each concave groove 22 and each concave arc surface 134 of the guiding column 13 (as Figure 7 shown).

[0074] Furthermore, a strip 23 is formed between any two adjacent concave grooves 22, and each strip 23 is respectively fitted corresponding to the approach channel 133. Additionally, a retaining ring 24 is formed inside each concave groove 22. At the bottom end of the retaining ring 24, there is an elastic hook 241, and a clearance space 242 is formed between the rear side of the elastic hook 241 and the inner wall surface of the cavity 12 of the insulating base 10 (as Figure 6 shown). A positioning groove 25 is provided on the peripheral wall of the rubber core 20 for the positioning strip 111 to be inserted and positioned. Moreover, at two corresponding positions on the front side of the rubber core 20, an elastic arm 26 is respectively provided. At the end of each elastic arm 26, a handle 261 is formed, and at the middle position of each elastic arm 26, a locking block 262 is formed. The locking block 262 is locked corresponding to the locking hole 112, and the handle 261 is fitted corresponding to the clamping groove 113.

[0075] Please continue to refer to Figure 4 、 Figures 6 to 8 shown. Each conductive terminal 30 is respectively disposed corresponding to each terminal cavity A. In this embodiment, the conductive terminal 30 is described as a male terminal, and it can also be a female terminal. Each conductive terminal 30 includes a connecting section 31, a fixing section 32 extending from the connecting section 31, and a conducting section 33 extending from the fixing section 32.

[0076] Furthermore, each connecting section 31 is provided with a core wire insertion hole 311 for a core wire B1 of a wire B to be inserted; each fixing section 32 has a retaining ring 321, a reduced neck section 322 formed at a position below the retaining ring 321, and a hook section 323 formed at the lower edge position of the reduced neck section 322.

[0077] During assembly, first, the rubber core 20 is slidably combined with the guiding post 13 of the insulating base 10 through its guiding hole 21. Then, each conductive terminal 30 is inserted corresponding to each terminal cavity A. When the hook section 323 reaches the position of the elastic hook 241, the elastic hook 241 is pushed by the hook section 323 and bends towards the clearance space 242, so that the conductive terminal 30 can easily enter the terminal cavity A. And after the elastic hook 241 passes through the hook section 323, under the action of its elastic restoring force, the elastic hook 241 will directly buckle and lock on the reduced neck section 322. At the same time, the retaining ring 321 is blocked by the retaining ring 24, and the elastic hook 241 is also restricted by the hook section 323. In this way, the conductive terminal 30 can be effectively prevented from being pulled out of the terminal cavity A in the reverse direction.

[0078] The connector of the present invention that is easy to assemble further includes a sleeve 40 and a screwing member 50. The sleeve 40 is sleeved on one side of the insulating base 10, and the screwing member 50 is connected to one end of the sleeve 40 and surrounds the outer periphery of the insulating base 10.

[0079] Please refer to Figure 9 As shown, in addition to being assembled in the manner of the above embodiments, the easily assembled connector of the present invention can also first insert each conductive terminal 30 into the respective grooves 22 of the rubber core 20, and then slide and combine the rubber core 20 and each conductive terminal 30 together through the guiding holes 21 on the guiding posts 13, thereby achieving the rapid combination of the rubber core 20, each conductive terminal 30 and the insulating base 10.

[0080] Please refer to Figures 10 to 12 As shown, the easily assembled connector of the present invention can be combined with a wire B and a socket assembly 9 to form a connector assembly. When combining, first sleeved the socket assembly 9 on the wire B in sequence, then connect each core wire B1 of the wire B with the connection section 31 of each conductive terminal 30, then insert the combined conductive terminal 30 and core wire B1 into the grooves 22 of the rubber core 20 one by one, and finally insert the rubber core 20 and each conductive terminal 30 into the cavity 12 of the insulating base 10 together. It is through the sliding fit of the guiding post 13 and the guiding hole 21, and with the help of the engaging block 262 of the elastic arm 26 corresponding to the engaging hole 112 for engaging and positioning. On the contrary, when taking out, press each lever 261 to make the engaging block 262 disengage from the engaging hole 112, and at the same time, expand and deform each elastic hook 241 outward by pulling, then the rubber core 20 and each conductive terminal 30 can be easily taken out from the insulating base 10 together, and each component can be reused repeatedly.
