Description

Cable connector

This new creation is about a cable connector.

Conventionally, connectors for connecting printed circuit boards (PCBs) with cables have been standardized according to various systems. In automobile technology, a system called FAKRA (Fachkreis Automobiltechnik) adopted as a standard in Europe and the United States is known. The FAKRA is the Automotive Standards Committee (Normenausschuss Kraftfahrzeuge) within the German Standards Association, which is concerned with international standardization in the automotive field. The standard promoted by FAKRA is named FAKRA Standard, which is the name of the organization that adopted the standard system. Generally used in automobiles, it is mostly used for GPS, AM/FM radio, mobile phones, airbag systems, multimedia devices, etc.

In the structure of the existing electrical connector conforming to the FAKRA standard, the bearing portion is extended from the insulator to facilitate placing the core of the terminal and the cable on the bearing portion, and then crimping with a jig. However, during the crimping process, the structural strength of the bearing portion is insufficient, which is often damaged due to excessive crimping force, thereby reducing the yield of the process.

The connection part has the above-mentioned escape space.

In an embodiment of the present invention, the above-mentioned escape space includes an opening of the connecting portion, and the external jig passes through the connecting portion through the opening.

In an embodiment of the invention, the connecting portion partially surrounds the first crimping portion, and the escape space includes a space where the connecting portion does not surround the first crimping portion and exposes the first crimping portion.

In an embodiment of the present invention, the second crimping portion partially extends away from the connecting portion and protrudes beyond the insulator to form a socket structure with the insulator.

In an embodiment of the invention, the above-mentioned cable has a ground layer, is located on the cable body, and is electrically insulated from the core. The third crimping portion includes a first part and a second part. The first part is crimped to cover the outer surface of the cable body, and the second part is crimped to cover the ground layer, so that the housing and the ground layer are electrically connected.

In an embodiment of the invention, the first crimping portion, the second crimping portion, and the third crimping portion respectively clamp the corresponding wire core, insulator, and cable body in an open-close structure.

In an embodiment of the invention, the above-mentioned cable connector is a socket electrical connector.

In an embodiment of the invention, the first crimping portion is suspended between the insulator and the cable.

In an embodiment of the present invention, the first crimping portion does not contact the insulator and the cable.

Based on the above, the cable connector has an escape space facing the first crimping portion through its housing, and the wire core is placed on the first crimping portion between the cable body and the insulator, thereby allowing the external jig to pass through Avoiding the space and smoothly abutting the first crimping portion is beneficial to the crimping operation. In other words, the cable connector only surrounds a part of the housing between the insulator and the cable body, and the part of the housing also has an escape space, so the process of crimping the wire core to the first crimping part In the middle, the external jig will not interfere with the structure of the shell, and can be smoothly crimped.

In order to make the above-mentioned features and advantages of the creation of the new model more obvious and understandable, the embodiments are specifically described below and described in detail in conjunction with the accompanying drawings.

FIG. 1 is a cable connector according to an embodiment of the novel creation. FIG. 2 illustrates the cable connector of FIG. 1 from another perspective. FIG. 3 is an exploded view of the cable connector of FIG. 1 before crimping, and the housing 140 and the terminal 130 shown in FIG. 3 are in a state where they are not crimped yet. Please refer to FIGS. 1 to 3 at the same time. In this embodiment, the cable connector 100 is a receptacle electrical connector conforming to the FAKRA standard, which includes a cable 110, an insulator 120, a terminal 130, and a housing 140, wherein the cable 110 The wire core 111 is provided, and the wire core 111 protrudes from the cable body 112 of the cable 110. The terminal 130 is disposed (inserted) in the insulator 120, and the terminal 130 has a first crimping portion 131 and a butting portion 132. The first crimping portion 131 protrudes out of the insulator 120, and the butting portion 132 is hidden in the insulator 120 Within but away from the cable 110, it serves as a signal transmission medium for the cable connector 100 to dock with another cable connector (plug electrical connector).

Furthermore, as shown in FIGS. 1 and 3, by crimping the core 111 of the cable 110 to the first crimping portion 131, the cable 110 and the insulator 120 are connected together, and the first pressure The connecting portion 131 is located between the insulator 120 and the cable 112. The housing 140 is assembled to the insulator 120 and the cable body 112, and the housing 140 has an escape space 144 to face the first crimping portion 131.

Further, the housing 140 has a second crimping portion 141, a third crimping portion 142 and a connecting portion 143, wherein the second crimping portion 141 is used for crimping and covering the insulator 120, that is, the insulator 120 is embedded It is provided in the second crimping portion 141. The third crimping portion 142 is crimped and covers part of the cable body 112. According to this, the insulator 120 and the cable 110 can be assembled together by the housing 140. Furthermore, the connecting portion 143 is connected between the second crimping portion 141 and the third crimping portion 142, and is also located between the cable body 112 and the insulator 120 to substantially face the first crimping portion 131.

4 is a schematic view of crimping the cable connector of FIG. 1. Please refer to FIG. 3 and FIG. 4 at the same time. The third crimping portion 142 of the housing 140 shown in the figure includes a first portion 142a and a second portion 142b. The crimping portion 131 is also in a state where it has not been crimped. Here, the crimping step is to first join the insulator 120 to the housing 140 and be covered by the second crimping portion 141. As shown in FIG. 2, the part of the combined second crimping portion 141 extends away from the connecting portion 143 It protrudes from the insulator 120 and forms a socket structure with the insulator 120 to facilitate docking with another cable connector (plug electrical connector).

Next, the terminal 130 is inserted into the insulator 120 in the axial direction X1, and the first crimping portion 131 is exposed and corresponds to the escape space 144 of the housing 140, as shown in FIG. 4; Then, the cable 110 is placed into the housing 140, so that the core 111 is placed in the first crimping portion 131, the cable body 112 is placed in the first portion 142a of the third crimping portion 142, and the cable 110 further has a connection located in the cable body 112 but exposed to the cable body 112 The ground layer 113 is electrically insulated from the core 111. After the cable 110 is placed in the housing 140, the ground layer 113 is placed in the second portion 142b of the third crimping portion 142; finally, a crimping tool (not shown) is used to respectively connect the first crimping portion 131 and the core 111. The first portion 142a of the third crimping portion 142 and the cable body 112, the second portion 142b of the third crimping portion 142, and the ground layer 113 perform corresponding crimping operations.

Based on the above, the cable connector 100 after the crimping process is completed, as shown in FIGS. 1 and 2, the first crimping portion 131 and the core 111 are crimped together to be fixed and electrically conductive, and the third crimping The first portion 142a of the portion 142 and the cable body 112 are crimped together and fixed, and the second portion 142b of the third crimping portion 142 and the ground layer 113 are crimped together and fixed and electrically conductive. Thereby, the first crimping portion 131, the second crimping portion 141, and the third crimping portion 142 respectively sandwich the corresponding core 111, the insulator 120, and the cable body 112 (and the ground layer 113) in an open-close structure. And the crimping at these places achieves the electrical conduction and the structure fixing effect at the same time, in which the housing 140 can electrically communicate with the ground layer 113 of the cable 110 to make the cable connector 100 and another cable Wire connectors (plug electrical connectors) can provide the required grounding effect when docked.

It is worth noting that the connecting portion 143 of the housing 140 is connected between the second crimping portion 141 and the third crimping portion 142 and is also located between the cable body 112 and the insulator 120, and has the aforementioned escape space 144. In this embodiment, the escape space 144 includes an opening V2 at the bottom of the connecting portion 143 and a space V1 around the first crimping portion 131 that is not surrounded by the physical structure of the connecting portion 143. In other words, the connecting portion 143 of this embodiment partially surrounds the first crimping portion 131, and the space V1 is a space where the connecting portion 143 does not surround the first crimping portion 131 and exposes the first crimping portion 131.

According to this, when the crimping operation is performed, the crimping tool moves into the space V1, and more importantly, the external jig 200 (shown in FIG. 4) can pass through the connecting portion 143 through the opening V2 and abut against the first压接部131。 The pressure part 131. In this way, the crimping tool contacts the upper and lower of the external jig 200 to complete the action of crimping the wire core 111 and the first crimping portion 131 together. It should be noted that this eliminates the need for an additional bearing structure to replace the terminal 130 inserted into the insulating portion 120, and instead uses an external jig 200 to replace it. Therefore, in addition to simplifying the structure of the cable connector 100, Effectively avoid the problem of insufficient structural strength of the existing bearing part. In other words, the first crimped portion 131 after crimping is suspended between the insulator 120 and the cable body 112 and does not substantially contact the insulator 120 and the cable body 112. The simplified cable connector eliminates the need for redundant support structures for the crimping process.

In summary, in the above-mentioned embodiment of the present invention, the cable connector has an escape space facing the first crimping portion through its housing, and the first crimping portion between the cable body and the insulator The wire core is placed on the top, so that the external jig can be smoothly abutted to the first crimping portion through the escape space, which is beneficial to the crimping operation. In other words, the cable connector only surrounds a part of the housing between the insulator and the cable body, and the part of the housing also has an escape space, so the process of crimping the wire core to the first crimping part In the middle, the external jig will not interfere with the structure of the shell, and can be smoothly crimped. This allows the crimped first crimping portion and the wire core to be substantially suspended outside the insulator and the cable body, that is, to simplify the structure of the cable connector without providing an additional support structure for crimping .
