An electronic connector is a conductor device for connecting electrical lines. The component can be used as a terminal for connecting different elements in a circuit system, or can be used for providing power and data connection between different circuit systems and devices. It is widely used in various electric lines to connect or disconnect electric circuits. Such connections may be temporary and convenient to plug and unplug, or may be permanent junctions between electrical devices or cables.

Fig. 1 shows a connector 1. The connector 1 may be composed of an inner crimp ferrule 2, an inner terminal 3, and an outer terminal 4. The outer terminal 4 includes a mating sleeve 5, an insulator 6, and a crimp assembly 7. The crimp assembly 7 includes a crimp portion 7a and a strip of material 7b remaining when the crimp assembly 7 is manufactured. In assembling or manufacturing the outer terminal 4 of the connector 1, the insulating member 6 and the crimping portion 7a of the crimping assembly 7 are connected in the axial direction, and then the mating sleeve 5 is fitted over the insulating member 6, thereby forming the outer terminal 4. Then, the inner terminal 3 with the inner crimp ferrule 2 crimped thereon is inserted from one end of the outer terminal 4 close to the crimp portion 7a, and then the crimp portion 7a is crimped to surround and fix the inner terminal 3, forming the connector 1.

However, with this prior design, the insulator 6, the crimp assembly 7, and the mating sleeve 5 need to be separately manufactured, and then the insulator 6, the crimp assembly 7, and the mating sleeve 5 are assembled together, so the design results in low production efficiency and high cost of the whole product.

In addition, the present disclosure is not limited to the specific embodiments described below, and may be implemented or applied by other different embodiments, and various modifications and changes may be made to the specific contents in the present specification without departing from the spirit of the present disclosure.

Specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. The drawings are for simplicity and clarity and are not intended to be drawn to scale, reflecting the actual dimensions of the structures described. To facilitate understanding, identical reference numerals have been used, where possible, to designate identical elements that are common to the figures.

An example connector 100 according to an embodiment is described below with reference to fig. 2 to 10.

Referring to fig. 2, a perspective block diagram of an exemplary connector 100 is shown. The connector 100 may include an outer terminal assembly 110 and an inner terminal assembly 120. Inner terminal assembly 120 is inserted in outer terminal assembly 110 along the y-axis negative direction.

Fig. 3 shows a perspective view of the outer terminal assembly 110. Fig. 4 showsbase:Sub>A perspective cross-sectional view of the outer terminal assembly 110 taken along linebase:Sub>A-base:Sub>A in fig. 3. Fig. 5 shows a top view of the outer terminal assembly 110 as viewed in the direction of arrow I of fig. 3 (i.e., from the positive z-axis direction toward the negative z-axis direction) when the reverse-folded tape 114 of the outer terminal assembly 110 is unfolded. Fig. 6 shows a bottom view of the outer terminal assembly 110 as viewed in the direction of arrow II of fig. 3 (i.e., from the negative z-axis direction toward the positive z-axis direction) when the reverse-folded tape 114 of the outer terminal assembly 110 is unfolded. The outer terminal assembly 110 of the present disclosure may be integrally formed of a conductive material. As an example, the outer terminal assembly 110 may be integrally formed by casting, punching, cutting, or the like.

As one non-limiting example, the outer terminal assembly 110 may include a mating part 111 and a crimping part 112, as shown in fig. 3 to 6. The mating part 111 and the crimping part 112 may be partially connected in an axial direction (e.g., a y-axis direction in fig. 3 and 4) of the connector 110 to form an intermediate connection part 113. The mating portion 111 may be located at a first side of the outer terminal assembly 110. The crimp portion 112 may be located on a second side of the outer terminal assembly 110 opposite the first side. The intermediate connecting portion 113 may be formed by an intermediate material, for example, to combine the fitting portion 111 and the crimping portion 112 on the same material tape.

In the process of integrally molding the mating portion 111 and the crimping portion 112, the intermediate connecting portion 113 is formed with a first notch 1131 in the circumferential direction (i.e., the direction around the axial direction), as shown in fig. 4 and 6. In order to ensure the strength of the outer terminal assembly 110, particularly at the first notch 1131, the outer terminal assembly 110 may further include a reverse fold strip 114. As shown in fig. 3, the inflection belt 114 may extend from the first notch 1131 along the circumferential direction of the connector 110 to surround the intermediate connection portion 113. The invaginated tape 114 surrounding the intermediate connecting portion 113 may have an edge 1141 in the axial direction. The edge 1141 may abut or engage an external structure, thereby serving to locate the outer terminal assembly 110.

As an example, referring to fig. 3-6, the invaginated tape 114 may include a docking portion 1142 and a surrounding portion 1143. As shown in fig. 4, the docking portion 1142 may be connected to the mating portion 111 and the crimping portion 112. The surrounding portion 1143 may extend circumferentially from the abutting portion 1142 to surround the intermediate connection portion 113. The width of the surrounding portion 1143 may be greater than the width of the docking portion 1142. As shown in fig. 5 and 6, a second notch 1144 may be formed at the end of the surrounding portion 1143. The first notch 1131 may substantially coincide with the abutment 1142 and the second notch 1144.

It will be appreciated that the crimp portion 112 has substantially the same outer shape as the crimp portion 4a shown in fig. 1 before being crimped. Fig. 2 to 4 show the state after crimping.

Fig. 7 shows a perspective schematic view of the inner terminal assembly 120. The inner terminal assembly 120 may include a core 121 and a positioning part 122. In assembling the connector 100, the core 121 may be inserted into the outer terminal assembly 110 from one end of the outer terminal assembly 110 near the crimp 112, and the inner terminal assembly 120 and the outer terminal assembly 110 may be mounted to each other by mating the positioning portion 122 of the inner terminal assembly 120 with the corresponding structure inside the outer terminal assembly 110. After being installed in place, the crimp section 112 may be crimped to enclose and secure the inner terminal assembly 110, and thus the inner terminal assembly 120 and the outer terminal assembly 110, relative to one another, thereby forming the connector 100 shown in fig. 2.

Alternatively, an inner crimp band 123 shown in fig. 8 may be crimped on the core 121 of the inner terminal assembly 120. The crimp band 123 may be a U-shaped band made of a conductive material. The core 121 may be wrapped with a crimp band 123 and the crimp band 123 crimped end-to-end so that the crimp band 123 is secured to and wraps around the surface of the core 121. The compression bonding tape 123 may optimize the electrical performance of the connector 100.

An insulator 130 as shown in fig. 9 may be sleeved between the outer terminal assembly 110 and the inner terminal assembly 120. The insulator 130 may include an insulator channel 131 into which the inner terminal assembly 120 is inserted. Insulator 130 may provide an insulating shield between outer terminal assembly 110 and inner terminal assembly 120.

The connector 110 may further include a housing 140. Fig. 10 is a partial cross-sectional view of the connector 110 including the housing 140. The outer terminal assembly 120 may be disposed within the housing channel 141 of the housing 140. An axial edge 1141 of the reverse tape 114 may abut an inner wall of the housing channel 141 for securing the outer terminal assembly 110 in place.

Referring now to fig. 11, an exemplary method 200 for manufacturing a connector according to an embodiment of the present disclosure is illustrated. The exemplary method 200 may be used to manufacture the connector 100 as described above. Without limitation, the method 200 may also be used to manufacture other connectors.

The method 200 starts at step 201. At step 201, the outer terminal assembly 110 may be integrally formed using a conductive material. The outer terminal assembly 110 may include a mating portion 111, a crimp portion 112, and a reverse fold strip 114. The mating portion 111 may be located on a first side (y-axis negative direction) of the outer terminal assembly 110. The crimp 112 may be located on a second side (positive y-direction) of the outer terminal assembly 110 opposite the first side. The mating part 111 may be connected with the crimping part 112 in an axially upper portion of the connector 100 to form an intermediate connection part 113. The intermediate connection portion 113 may be formed with a first notch 1131 in a circumferential direction. The reverse fold strap 114 may extend from the first notch 1131 in the circumferential direction of the connector 100 to surround the intermediate connection portion 113.

At step 202, the surrounding portion 1143 of the reverse fold strip 114 may be circumferentially bent such that the reverse fold strip 114 surrounds at least the first notch 1131.

At step 203, the insulator 130 may be inserted into the outer terminal assembly 110 from the second side of the outer terminal assembly 110 in the y-axis negative direction and fixed in place. The insulator 130 may include an insulator channel 131 into which the inner terminal assembly 120 is inserted.

At step 204, the inner terminal assembly 120 may be inserted into the outer terminal assembly 110 from the second side of the outer terminal assembly 110 such that the core 121 of the inner terminal assembly 120 enters and passes through the insulator channel 131 of the insulator 130.

At step 205, the crimp 112 may be crimped to surround and secure the inner terminal assembly 120.

At step 206, the outer terminal assembly 110 may be loaded into the housing 140. The housing 140 may include a housing channel 141. The outer terminal assembly 110 may be mounted to the housing 140 by inserting the outer terminal assembly 110 with the inner terminal assembly 120 mounted therein into the housing channel 141. The outer terminal assembly 110 can be secured in place by abutting the axial edges 1141 of the turnback strap 114 against the inner wall of the housing channel 141.

Thus, by the method 200, the connector 100 shown in fig. 2 can be manufactured.
