Description

Conductive terminal

The present invention is to provide a conductive terminal, particularly a conductive terminal for electrically connecting a cable.

With the advancement of technology, electric vehicles with green energy and environmental protection concepts have also become popular. Of course, the addition of power stations, charging stations or charging facilities is also becoming popular. Among them, a charging gun for charging an electric vehicle has, for example, five or seven conductive terminals. Some of the conductive terminals are used to transmit electrical energy, and other conductive terminals are used to transmit control signals or detect signals.

The conventional method of assembling the conductive terminals is generally to insert the elastic portion from the first opening portion of the outer sleeve into the receiving portion in the outer casing. Therefore, the guide portion in the elastic portion tends to be damaged or damaged by the shrinkage structure of the first opening portion during this process. Even the elastic portion is broken or the elastic portion is broken. Therefore, the elastic portion loses the function of the existing elastic clamping electric pin and the fixing portion of the outer sleeve. Therefore, the product yield of the conductive terminals is greatly reduced.

Furthermore, another technique for assembling the conductive terminals is to reduce the damage rate or defective rate of the elastic portion by relaxing the inner diameter of the neck portion of the first opening portion. However, since the inner diameter of the constricted structure of the first opening portion is relaxed, the elastic portion tends not to be fixed in the accommodating portion of the outer sleeve, and even the elastic portion is drawn out following the electrical pin.

The present invention provides a conductive terminal that passes through the elastic portion from the second opening portion of the outer sleeve into the receiving portion to reduce the damage rate of the elastic portion. Improve the ease of use of the conductive terminals.

The present invention provides a conductive terminal including an outer sleeve, an elastic portion, an inner sleeve and a connecting rod. The outer sleeve has a first opening portion, a second opening portion and a receiving portion. The first opening portion communicates with the second opening portion via the receiving portion. The elastic portion has a plurality of elastic pieces, and the first end and the second end of each elastic piece are respectively a guide portion. The inner sleeve is used to sleeve the elastic portion. The connecting rod is used for electrically connecting a cable. Wherein, the first opening portion is a shrinkage structure, the inner diameter of the shrinkage structure is smaller than the outer diameter of the elastic portion, and the inner diameter of the second opening portion is larger than the outer diameter of the elastic portion.

In summary, the conductive terminal of the present embodiment passes through the elastic portion from the second opening portion of the outer sleeve into the design of the accommodating portion to reduce the damage rate of the elastic portion. The first opening portion is a constricting structure for blocking the sliding of the elastic portion or following the electrical pin to be extracted, thereby improving the product yield of the conductive terminal and the convenience of use.

FIG. 1 is a perspective exploded view of a conductive terminal according to an embodiment of the present invention. Please refer to Figure 1. A conductive terminal 1 includes an outer sleeve 10, an elastic portion 12, an inner sleeve 14, and a connecting rod 16. The outer sleeve 10, an elastic portion 12 and an inner sleeve 14 are common members. The connecting rods 16a, 16b can be replacements for the connecting rod 16. That is, any of the connecting rods 16, 16a, 16b can be assembled with the outer sleeve 10, the elastic portion 12, and the inner sleeve 14 as the conductive terminals 1.

For convenience of explanation, the present embodiment will be described with reference to "the connecting rod 16 and the outer sleeve 10, the elastic portion 12, and the inner sleeve 14 are assembled into the conductive terminal 1". The structure, structure and function of the connecting rods 16, 16a, 16b are similar. For example, the connecting rod 16a has a first connecting portion 161a, a second connecting portion 162a, a stopping portion 164a, a first venting structure H1a and a Two vent structure H2a. Similarly, the connecting rod 16b also has a first connecting portion 161b, a second connecting portion 162b, a stopping portion 164b, a first exhaust hole structure H1b, and a second exhaust hole structure H2b. The structure, construction and function of the connecting rods 16, 16a, 16b will be described in detail later.

In practice, the conductive terminal 1 is, for example, a conductive pin of a charging gun. For example, the charging gun has five or seven conductive terminals 1. In addition, the conductive terminal 1 can also be used in electrical plugs, electrical outlets or other electrical equipment. This embodiment is not limited to the operation state of the above-described conductive terminal 1.

The outer sleeve 10 has a first opening portion 101, a second opening portion 102 and a receiving portion SP. In practice, the first opening portion 101 is located at the front end of the outer sleeve 10, and the second opening portion 102 is located at the rear end of the outer sleeve 10. The first opening portion 101 communicates with the second opening portion 102 via the accommodating portion SP. The first opening portion 101 is, for example, a constricted structure. The inner diameter R1 of the constricted structure is smaller than the outer diameter R3 of the elastic portion 12. Therefore, the first opening portion 101 can stop the elastic portion 12 or the inner sleeve 14 from sliding out of the open end, falling out or following the electrical The pin is pulled out.

The elastic portion 12 has a plurality of elastic pieces 120 or more. The first end and the second end of each elastic piece 120 are respectively a guide portion 122. The guide portions 122 contact or abut against the receiving portion SP. In practice, the elastic portion 12 is disposed in the accommodating portion SP of the outer sleeve 10. The elastic portion 12 is, for example, a grid-like elastic structure, and each of the elastic pieces 120 is an inwardly-shaped concave elastic piece that is bent inward, as shown in FIG. This embodiment does not limit the aspect of the elastic portion 12.

The inner sleeve 14 is used to sleeve the elastic portion 12. For example, the inner sleeve 14 is sleeved with the elastic pieces 120, and the guide portions 122 are fastened to the inner sleeve 14, as shown in FIG. In practice, the inner sleeve 14 is for assembly with the resilient portion 12. For example, the elastic portion 12 is configured to elastically electrically couple an electrical pin. When an electrical pin is inserted into the jack space surrounded by the elastic portion 12, the inwardly bent elongated elastic piece that is bent inward will expand toward the inner sleeve 14.

The connecting rod 16 is electrically connected to a cable (not shown). In practice, the connecting rod 16 has a first connecting portion 161, a stopping portion 164 and a second connecting portion 162. The stopper portion 164 is connected between the first connection portion 161 and the second connection portion 162. In practice, the first connecting portion 161 enters the receiving portion SP of the rear end from the second opening portion 102 of the outer sleeve 10. The second connecting portion 162 is for electrically connecting the cable. For example, the second connecting portion 162 is connected by a riveting method to connect the cable.

In particular, the connecting rod 16 is, for example, a connector for 16 amps, 32 amps, 80 amps, or other numerical amperage current. Therein, for example, the outer diameter of the second connecting portion 162b of 80 amps is larger than the outer diameter of the second connecting portion 162 of, for example, 32 amps. For example, the outer diameter of the second connecting portion 162 of 32 amps is larger than the outer diameter of the second connecting portion 162a of, for example, 16 amps, such as the second connecting portions 162, 162a, 162b illustrated in FIG. In short, the larger the current withstand by the connecting rods 16, 16a, 16b, the larger the outer diameter of the second connecting portions 162, 162a, 162b.

The first connecting portion 161 of the connecting rod 16 is of a fixed size to fit the outer sleeve 10. The second connecting portion 162 of the connecting rod 16 has a plurality of sizes. Thereby, the user can replace the different connecting rods 16 according to the power transmission requirements of the charging gun. For example, use When a power transmission requirement of a 80 amp rechargeable gun is required, the user (or manufacturer) may select the connecting rod 16b to perform assembly of the conductive terminal 1. For another example, when the user needs the power transmission requirement of the 32 amp charging gun, the user (or the manufacturer) can select the connecting rod 16a to perform the assembly of the conductive terminal 1.

It should be noted that the prior art assembly of the conductive terminal 1 causes the elastic portion 12 to enter the accommodating portion SP from the first opening portion 101. Therefore, the guide portions 122 of the elastic portion 12 live to be broken or damaged by the shrinkage structure of the first opening portion 101. Therefore, the elastic portion 12 will lose its existing function. Further, in order to overcome the above problems, the prior art tends to relax the inner diameter R1 of the neck opening structure of the first opening portion 101 to reduce the damage rate or defective rate of the elastic portion 12. However, since the inner diameter R1 of the constricted structure of the first opening portion 101 is relaxed, the elastic portion 12 tends not to be fixed in the accommodating portion SP, and even the elastic portion 12 is drawn out following the electrical pin.

Based on the above, the present embodiment does not relax the inner diameter R1 of the neck opening structure of the first opening portion 101, but the elastic portion 12 enters the receiving portion SP of the front end from the second opening portion 102. The inner diameter R2 of the second opening portion 102 is larger than the outer diameter R3 of the elastic portion 12. Therefore, the guide portions 122 of the elastic portion 12 are not broken or damaged by the second opening portion 102. Furthermore, the elastic portion 12 is limited by the constricted structure of the first opening portion 101. Therefore, the elastic portion 12 is fixed in the accommodating portion SP, and it is difficult to follow the electrical pin to be withdrawn. Thereby, the conductive terminal 1 of the present embodiment overcomes the above problems, and improves the production yield and ease of use of the conductive terminal 1.

The inner diameter R2 of the second opening portion 102 is larger than the outer diameter R3 of the elastic portion 12. The inner diameter R2 of the second opening portion 102 is larger than the outer diameter of the inner sleeve 14 (not shown). The elastic portion 12 and the inner sleeve 14 enter the receiving portion SP of the front end from the second opening portion 102 of the outer sleeve 10. The first connecting portion 161 of the connecting rod 16 enters from the second opening portion 102 of the outer sleeve 10 to the receiving portion SP of the rear end. Therefore, the constricted structure of the first opening portion 101 blocks the elastic portion 12 and the inner sleeve 14, and the first connecting portion 161 of the connecting rod 16 abuts against the elastic portion 12 and the inner sleeve 14.

Further, the first connecting portion 161 is configured with a first venting hole structure H1. first row The pore structure H1 penetrates through the first connection portion 161. Next, the second connecting portion 162 is configured with a second venting structure H2. The second vent hole structure H2 penetrates the second connecting portion 162. In addition, the outer sleeve 10 has two matching hole structures T1, which are respectively in communication with the first venting hole structure H1. This embodiment does not limit the aspect of the conductive terminal 1.
