However, due to its structural characteristics, the TPA used for coaxial cable terminals, such as the conventional FAKRA terminal described above, does not completely match the installation groove where the TPA is penetrated and coupled at the primary locking position, and there is some height difference (step). occurs. As a result, in the process of inserting and coupling the coaxial cable terminal into the terminal groove, there was a problem in which the restraining jaw of the coaxial cable terminal was caught in the step and incomplete coupling occurred, preventing it from being completely inserted into the installation groove.

At the same time, even if the terminal for the coaxial cable is incompletely connected, additional problems such as product defects or malfunctions are caused because the operator does not accurately recognize this.

In addition, the above-described TPA is located in a restraining groove made in the mold member on the circumferential surface of the coaxial cable terminal and is configured to prevent only the forward and backward movement of the coaxial cable terminal, but also prevents the upward and downward movement or radial direction of the coaxial cable terminal. The flow of was not prevented. As a result, there was a problem that the reliability of the product was reduced, such as noise caused by vibration.

Next, a preferred embodiment of the connector assembly of the present invention will be described with reference to the attached FIGS. 1 to 24.

The attached Figures 1 to 3 are perspective views of each state of the connector assembly according to an embodiment of the present invention, and Figures 4 to 7 are state diagrams of the connector assembly in each direction according to an embodiment of the present invention.

As shown in these drawings, the connector assembly according to an embodiment of the present invention includes a terminal position assurance (TPA) (hereinafter referred to as “TPA”) 300 that restrains the terminal member 100. In addition, the TPA (300) is formed so that the portion restraining the terminal member (100) is elastically deformed. As a result, the terminal member 100 is prevented from being caught in the installation groove 230 where the TPA 300 is installed during the process of mounting the terminal member 100 to the terminal groove 210, and the terminal member 100 can be stably installed and maintained.

The connector assembly according to this embodiment of the present invention will be described in more detail for each component as follows.

First, the connector assembly according to an embodiment of the present invention includes a terminal member 100.

The terminal member 100 may be formed as a FAKRA terminal to which a coaxial cable 101 is connected at one end.

As shown in Figure 1 attached, a barrel 110 is provided at one end of the terminal member 100, and the coaxial cable 101 is installed to be held in the barrel 110.

An external contact 120 is provided at the other end of the terminal member 100 to be connected to the other terminal member. At this time, an internal contact 130 surrounding the coaxial axis of the coaxial cable 101 may be further provided within the external contact 120.

Additionally, a flange portion 140 is provided around the terminal member 100. The flange portion 140 forms a region restricted by the TPA 300, which will be described later.

The flange portion 140 includes a front flange 141, a rear flange 142, and a restraining groove 143 provided between the two flanges 141 and 142. The restraining groove 143 is formed to have a width sufficient to accommodate the restraining portion 320 of the TPA 300, which will be described later, and a depth considering the allowable operating distance of the TPA 300. At this time, the depth considering the allowable operating distance may be a depth that allows the restraint portion 320 of the TPA 300 to be in close contact when the TPA 300 is completely coupled to the connector housing 200. there is.

Meanwhile, the terminal member 100 may be formed of a conductive metal capable of conducting electricity, and the flange portion 140 may be formed of a mold of an insulating material. That is, even if the terminal member 100 is connected to the terminal member (not shown) of the counterpart connector, it is configured to prevent short circuiting in the area where the flange portion 140 comes into contact.

Next, the connector assembly according to an embodiment of the present invention includes a connector housing 200.

The connector housing 200 is a part that forms the body of the connector assembly, and the terminal member 100 to which the coaxial cable 101 is connected and each terminal (not shown) to which other wires (not shown) are connected. omitted) is made to provide a site where they are installed.

As shown in the attached FIGS. 1 to 3, 5, 8, and 9, the connector housing 200 has a terminal groove 210 into which the terminal member 100 is inserted and other terminals are inserted and installed. A plurality of terminal seating grooves 220 are formed.

The terminal groove 210 is formed to penetrate the front and back of the connector housing 200 at one side of the connector housing 200, and each terminal seating groove 220 is formed at a central portion of the connector housing 200. and is formed to penetrate the front and back of the connector housing 200 at the other side.

Meanwhile, a stopper protrusion 211 is formed within the terminal groove 210 to prevent over-insertion of the terminal member 100. That is, when the terminal member 100 is completely inserted, the front flange 141 forming the terminal member 100 collides with the stopper protrusion 211 to prevent further insertion.

Additionally, an installation groove 230 is formed in the connector housing 200 for installation of the TPA 300, which will be described later.

The installation groove 230 is formed to penetrate from the upper surface of the connector housing 200 to the area where the terminal groove 210 and each terminal seating groove 220 are formed.

Additionally, locking protrusions 240 are formed on both inner surfaces of the connector housing 200. The locking protrusion 240 is a structure provided so that the TPA 300, which will be described later, can be restrained when installed in the installation groove 230.

Next, the connector assembly according to an embodiment of the present invention is configured to include a terminal position assurance member (TPA) 300.

The TPA (300) penetrates the circumference of the connector housing (200) and is inserted into the installation groove (230) to restrain the terminal member (100) installed to penetrate the terminal groove (210).

As shown in the attached FIGS. 1, 10, and 11, the TPA 300 includes a body portion 310, a restraining portion 320 that restrains the terminal member 100, and the connector housing 200. It consists of a locking portion 330 that is restrained.

Here, the body portion 310 forming the TPA 300 is an external body formed of a block body.

In addition, the constraint portion 320 forming the TPA 300 is formed on a portion of the body portion 310 to be elastically deformable. The restraint portion 320 includes a close contact end 321 positioned to be spaced apart from the body portion 310, and a connecting end 322 connecting both ends of the close contact end 321 to the body portion 310. It is composed.

The close contact end 321 is formed to have a front-to-back width and a top-and-bottom thickness sufficient to allow elastic deformation and is inserted into the restraining groove 143 of the terminal member 100. At this time, the front-to-back width of the close contact end 321 is formed to be smaller than the front-to-back width (distance between two flanges) of the restraining groove 143, and the top and bottom thickness of the close contact end 321 is formed to be thinner than the front-to-back width. . As a result, the close contact end 321 can be elastically deformed when pressed in a state of contact with the terminal member 100.

The close contact end 321 is spaced apart from the body portion 310 by a distance sufficient to allow elastic deformation, and is rounded so as to surround the restraining groove 143 during elastic deformation. At this time, the close contact end 321 is formed to be rounded so as to be pinched between the two connection ends 322.

At the same time, the close contact end 321 is positioned to match the communication area between the terminal groove 210 and the installation groove 230 until it is inserted and coupled to the restraining groove 143. That is, because the close contact end 321 can be elastically deformed, even if a portion passes through the installation groove 230 and protrudes into the terminal groove 210, in the process of inserting the terminal member 100 into the terminal groove 210, The interference caused by the close contact end 321 is only minimal and insertion defects do not occur.

The connection end 322 is formed to extend vertically from both ends of the close contact end 321 to the body portion 310, and when the close contact end 321 is elastically deformed, the close contact end 321 It additionally plays the role of supporting the central part to be transformed into a convex shape. As a result, the close contact end 321 can wrap and grip a portion of the outer peripheral surface of the restraint groove 143 of the terminal member 100.

In addition, the locking portion 330 forming the TPA 300 is located on both sides of the body portion 310 and has locking protrusions 331 and 332 on the outer surface that are caught and restrained by the locking protrusion 240 of the connector housing 200. is formed and achieved.

In particular, the locking protrusions 331 and 332 of the locking portion 330 are provided in plural numbers (eg, two) and are arranged to be vertically spaced apart from each other. This structure allows the TPA 300 to perform preliminary bonding and binding bonding sequentially. At this time, the preliminary coupling is a coupling in which the terminal member 100 is not constrained, and the constraining coupling is a coupling in which the terminal member 100 is constrained. At the time of preliminary coupling, the locking protrusion 331 located on the upper side of the two locking protrusions 331 and 332 is restrained by the locking protrusion 240, and when the restraint coupling is performed, the locking protrusion 331 located on the lower side of the two locking protrusions 331 and 332 is restrained. The device 332 is restrained by the locking jaw 240.

Meanwhile, the TPA 300 has a sensing member 340 that protrudes out of the body 310 by being pushed by the close contact end 321 when the close contact end 321 of the restraining part 230 is excessively deformed. More is provided. That is, if the terminal member 100 is misassembled and an assembly defect occurs, such as the front flange 141 of the flange portion 140 being caught in the installation groove 230, the sensing member 340 is detected by the body portion ( It protrudes further to the outer surface of the connector 310), allowing the worker to visually check this or to accurately recognize that it is not connected to the other connector.

The lower end of the sensing member 340 is located adjacent to the upper central side of the contact end 321, and the upper end is elastically deformably connected to the upper surface of the body portion 310.

In the following, the process of coupling the terminal member 100 to the connector housing 200 of the connector assembly according to the above-described embodiment of the present invention and restraining it with the TPA 300 will be described in more detail.

First, the terminal member 100, connector housing 200, and TPA 300 are provided individually.

Then, the TPA 300 is inserted and installed into the installation groove 230 of the connector housing 200 provided in this way. At this time, the TPA 300 ensures that the upper locking protrusion 321 of the locking protrusions 321 and 322 formed on both outer surfaces is in a pre-engaged state on the locking protrusion 240 of the connector housing 200. Its state is as shown in the attached Figures 12 to 15.

Then, the terminal member 100 is inserted and installed into the terminal groove 210 of the connector housing 200. This is as shown in the attached FIGS. 16 to 18. At this time, while the terminal member 100 is being inserted, the front flange 141 forming the flange portion 140 of the terminal member 100 may be inserted into the installation groove 230 communicating with the terminal groove 210. there is.

However, the connection portion between the installation groove 230 and the terminal groove 210 is where the close contact end 321 of the TPA 300 is located, and in particular, the close contact end 321 is the connection between the terminal grooves 210. As it is positioned to match the area, the front flange 141 of the terminal member 100 is inserted into the installation groove 230 or is prevented from getting caught.

When the terminal member 100 is completely inserted into the terminal groove 210 of the connector housing 200 through the above process, the front flange 141 hits the stopper protrusion 211 in the terminal groove 210 and is no longer inserted. . In addition, the restraining groove 143 between the two flanges 141 and 142 forming the terminal member 100 is positioned to coincide with the installation groove 230.

Meanwhile, while inserting and installing the terminal member 100 into the terminal groove 210 of the connector housing 200, other terminals may be additionally inserted and installed into each terminal seating groove 220 of the connector housing 200. there is.

Then, after the terminal member 100 and other terminals are completely inserted and installed into the terminal groove 210 and each terminal seating groove 220 of the connector housing 200, the TPA 300 is additionally moved downward. This is as shown in the attached FIGS. 19 to 21.

Accordingly, the close contact end 321 forming the TPA 300 is inserted into the restraining groove 143 between the two flanges 141 and 142 forming the terminal member 100 and comes into close contact with the restraining groove 143, and continues to do so. As elastic deformation occurs, the outer surface of the restraint groove 143 is wrapped.

At the same time, of the two locking protrusions 321 and 322 forming the TPA 300, the lower locking protrusion 322 is caught and restrained by the locking protrusion 240 of the connector housing 200.

Accordingly, the terminal member 100 is constrained to be installed in the connector housing 200, and thus assembly of the connector is completed.

Meanwhile, in the process of inserting and installing the terminal member 100 into the terminal groove 210 of the connector housing 200, the terminal member 100 is inserted at an angle due to an operator's mistake, and the front flange 141 is installed. A problem of getting caught in the groove 230 may occur.

Even if incorrect coupling of the terminal member 100 occurs in this way, if the TPA (300) is forcibly moved further downward, the lower locking protrusion 322 of the TPA (300) will be connected to the locking protrusion 240 of the connector housing 200. You may be caught and arrested.

However, when the terminal member 100 is incorrectly coupled as described above, the close contact end 321 forming the TPA 300 is excessively deformed to be convex upward, pushing the sensing member 340 located on the upper side upward. As a result, the upper end of the sensing member 340 protrudes more than the outer surface of the body portion 310. This is as shown in the attached FIGS. 22 to 24.

Accordingly, the operator can recognize that the terminal member 100 is incorrectly coupled by visually checking whether the sensing member 340 protrudes. Even if the visual confirmation is not made, considering that the counterpart connector is not accurately coupled due to the sensing member 340 protruding from the surface of the connector housing 200 when coupled with the counterpart connector, the operator may experience poor coupling between these two connectors. By checking, it may be recognized that the terminal member 100 is incorrectly coupled.

In this way, the connector assembly of the present invention and the TPA 300 used therein are formed so that the portion (close contact end 321) that contacts the restraining groove 143 of the flange portion 140 of the terminal member 100 is elastically deformable. Therefore, it is possible to grip the restraint groove 143 rather than simply contacting the restraint groove 143, thereby preventing the terminal member 100 from flowing back and forth or moving up and down.

In addition, the connector assembly of the present invention and the TPA 300 used therein can accurately recognize incorrect coupling of the terminal member 100 by confirming that the sensing member 340 protrudes due to excessive deformation of the contact end 321. There will be.

In the above, even though all the components constituting the embodiment according to the present invention have been described as being combined or operated in combination, the present invention is not necessarily limited to this embodiment. That is, as long as it is within the scope of the purpose of the present invention, all of the components may be operated by selectively combining one or more of them. In addition, terms such as “include,” “comprise,” or “have” described above mean that the corresponding component may be present, unless specifically stated to the contrary, and therefore do not exclude other components. Rather, it should be interpreted as being able to include other components.
