A coaxial cable terminal is prevented from being pushed by a lance to be bound by a clamping edge in the process of passing through a terminal setting hole formed in a connector housing.

Description

Technical Field

[0001] The present invention relates to a coaxial cable connector assembly having a position ensuring member and a connector housing thereof, which has a novel guide structure capable of smoothly inserting a coaxial cable into the coaxial cable connector assembly. Background Art

[0002] Generally, connector assemblies are mainly used in electronic products and are devices used to connect signals or power between two components.

[0003] Such a connector assembly is provided such that a male connector and a female connector form a pair, and the two components are electrically connected to each other by combining the male connector and the female connector.

[0004] The male connector is configured to include a male housing and male terminals provided in the male housing, and the female connector is configured to include a female housing and female terminals provided in the female housing.

[0005] On the other hand, in connectors using coaxial cable terminals (e.g., FAKRA terminals), the terminals are held in place within the terminal slots of the connector housing (female housing) by a terminal position assurance component (TPA). Specifically, the TPA grips a portion of the outer surface of the terminal, thereby maintaining the terminal's position within the connector housing.

[0006] For this, please refer to the disclosure of Japanese Patent Publication No. 10-2023-0005616. The TPA for such conventional terminals is formed so as to surround the terminals, thereby enabling the terminals to be stably mounted.

[0007] On the other hand, a terminal installation hole is formed in the connector housing to which the terminal is mounted, and the terminal is installed so as to penetrate the terminal installation hole.

[0008] Furthermore, a lance is provided within the terminal receiving hole to support the terminal and prevent it from being pushed within the terminal receiving hole. This lance is provided within the terminal receiving hole and is configured to elastically deform in a direction perpendicular to the axial direction of the terminal receiving hole. Specifically, when the terminal passes through, it is pushed and deformed in the vertical direction by the terminal. When the terminal is placed in a fixed position, it returns to its original position and is engaged with the rear end of the step formed in the terminal, thereby preventing the terminal from moving backward (moving in the direction of separation).

[0009] At the same time, an annular engaging ridge is formed on the inner peripheral surface of the terminal installation hole so as to allow the front end of the terminal to pass through but to block the front end of the step portion formed on the terminal.

[0010] However, the aforementioned prior art structure has the following problem: when the terminal is inserted through the terminal receiving hole, the lance applies a vertical pressure, causing the front end of the terminal to tilt downward and the front face of the front end to collide with the lower end of the engaging edge, causing the terminal to engage. In other words, when the terminal is inserted, the pressure from the lance causes the terminal to collide with the engaging edge, making smooth insertion difficult.

[0011] In order to solve the above problem, conventionally, the front edge corners of the coaxial cable terminal are chamfered so that the edge corners are formed obliquely.

[0012] However, even if the front end corners of the terminals are chamfered, there will still be vertical surfaces, so it is inevitable that the terminals will be caught at the catch edges.

[0071] The following is a detailed description of some embodiments of the present invention using schematic diagrams. It should be noted that when assigning reference numerals to the structural elements of the various drawings, the same reference numerals should be used whenever possible for identical structural elements, even if they are assigned to different drawings. Furthermore, when describing the embodiments of the present invention, if a detailed description of a related known structure or function is deemed detrimental to understanding the embodiments of the present invention, the detailed description will be omitted.

[0072] Furthermore, when describing the structural elements of the embodiments of the present invention, terms such as first, second, A, B, (a), and (b) may be used. Such terms are merely intended to distinguish the structural element from other structural elements, and the nature, order, or sequence of the corresponding structural elements are not limited by such terms. When a structural element is referred to as being "connected," "combined," or "in contact with" other structural elements, it may be that the structural element is directly linked or directly connected to the other structural elements, and it should also be understood that other structural elements may be "connected," "combined," or "in contact with" each other.

[0073] Attached Figures 1 to 20 Detailed Description of the Invention A coaxial cable connector assembly and its housing are shown in FIG.

[0074] As shown in these figures, the connector assembly of the present invention includes a structure for attaching a coaxial cable terminal 200 connected to a coaxial cable 100 and simultaneously coupling with a counterpart connector (not shown).

[0075] In particular, according to the coaxial cable connector assembly and its connector housing of the present invention, in order to restrict the forward movement of the coaxial cable terminal 200, the engaging ridge 330 provided in the connector housing 300 is configured to be guided at different times depending on the outer peripheral position of the stepped portion 211 formed in the coaxial cable terminal 200. This eliminates the difficulty in inserting the coaxial cable terminal 200 due to the engaging ridge 330.

[0076] The coaxial cable connector assembly and the connector housing thereof according to the present invention will be described in more detail below based on each structure.

[0077] First, the coaxial cable connector assembly of the present invention includes a coaxial cable terminal 200 .

[0078] As attached Figures 1 to 6 As shown, the coaxial cable terminal 200 may be formed by a FAKRA terminal with the coaxial cable 100 connected to the rear end. Specifically, the coaxial cable terminal 200 includes an outer terminal 210 having a cylindrical shape and accommodating the coaxial cable 100 while forming an outer shape, and an inner terminal 220 located at the center of the outer terminal 210 and connected to the core wire 101 of the coaxial cable 100.

[0079] An insulator 230 may be provided between the external terminal 210 and the internal terminal 220 for mutual insulation.

[0080] A stepped portion 211 is formed on the outer periphery of the external terminal 210. The stepped portion 211 is a portion having a larger outer diameter than the front end portion of the external terminal 210. The stepped portion 211 can be formed to have a depth and length set so that it can be restrained by a lance 230 of the connector housing 200 and a TPA (not shown) (described later).

[0081] Then, the coaxial cable connector assembly of the present invention includes a connector housing 300 .

[0082] The connector housing 300 forms the main body of the connector assembly.

[0083] Such a connector housing 300 may include a connector receiving portion 310 for receiving the opposite-side connector and a terminal setting portion 320 for setting the coaxial cable terminal 200 .

[0084] The terminal installation portion 320 includes a terminal installation hole 321 into which the coaxial cable terminal 200 is inserted.

[0085] On the other hand, the terminal installation portion 320 of the connector housing may further include a terminal groove 322 for a terminal connected to an electric wire other than the coaxial cable 100 .

[0086] On the other hand, the terminal setting hole 321 may be provided as one or more than two. For example, as shown in the attached figure, the terminal setting hole 321 may be provided as two and formed to be arranged side by side in the horizontal direction of the terminal setting portion 320. Although not shown, the terminal setting hole 321 may also be formed to be arranged side by side in the vertical direction of the terminal setting portion 320.

[0087] Furthermore, the terminal installation hole 321 may be formed to penetrate from the rear end of the terminal installation portion 320 to the front end connected to the connector receiving portion 310. Thus, the front end of the coaxial cable terminal 200 placed in the terminal installation hole 321 is configured to partially protrude into the connector receiving portion 310.

[0088] Furthermore, a terminal installation portion 320 forming the connector housing 300 is provided with an installation groove 323 for installing a terminal position assurance member (TPA) (not shown).

[0089] The arrangement groove 323 is formed in a direction perpendicular to the formation direction of the terminal arrangement hole 321 and each terminal groove 322. That is, the arrangement groove 323 is formed in the vertical direction of the terminal arrangement portion 320.

[0090] The installation groove 323 is formed to extend from the upper surface of the terminal installation portion 320 in the connector housing 300 to the terminal installation hole 321 and each terminal groove 322. Thus, the TPA inserted into the installation groove 323 can simultaneously restrain the coaxial cable terminal 200 placed in the terminal installation hole 321 and the terminal (not shown) placed in each terminal groove 322.

[0091] The installation groove 323 may be formed in a position taking into account the position of the stepped portion 211 of the coaxial cable terminal 200. That is, when the coaxial cable terminal 200 is fully inserted and installed in the terminal installation hole 321, the installation groove 323 is located behind the stepped portion 211.

[0092] A lance 324 is formed within the terminal receiving hole 321. This lance 324 is provided to engage and restrain the rear end of the stepped portion 211. Specifically, the lance 324 engages with the rear end of the stepped portion 211 of the coaxial cable terminal 200, thereby preventing the coaxial cable terminal 200 from moving backward.

[0093] The lance 324 is formed into a cantilever structure within the terminal installation hole 321 and is elastically deformable in the vertical direction. A restraining rib 324a is formed at the distal end of the lance 324, and the restraining rib 324a gradually protrudes into the terminal installation hole 321 as it moves forward (in the direction of terminal insertion).

[0094] Furthermore, a locking ridge 330 is formed protruding from the inner circumferential surface of the terminal receiving hole 321 formed in the connector housing 300. This locking ridge 330 is provided to engage and restrain the front end of the stepped portion 211. Specifically, the locking ridge 330 prevents the stepped portion 211 of the coaxial cable terminal 200 from protruding excessively forward.

[0095] On the other hand, the engaging edge 330 may be formed to guide the movement of the front end of the coaxial cable terminal 200. That is, the front end of the coaxial cable terminal 200 may be moved along the axial center of the terminal setting hole 321, thereby setting the coaxial cable terminal 200 in a fixed position.

[0096] To this end, the front corners of the engaging ridges 330 (corners at the terminal entrance) can be formed to be inclined inwardly toward the axial center of the terminal setting hole 321, in the insertion direction of the coaxial cable terminal 200. In other words, by guiding the outer periphery of the coaxial cable terminal 200 through the inclination formed by the front corners of the engaging ridges 330, the axial center of the coaxial cable terminal 200 can be aligned with the axial center of the terminal setting hole 321.

[0097] In particular, in an embodiment of the present invention, during installation in the terminal setting hole 321, even if the front end of the coaxial cable terminal 200 (specifically the end of the external terminal) is tilted downward, it can be guided to pass smoothly without being stuck on the clamping edge 330.

[0098] To this end, in the embodiment of the present invention, the engaging ridge 330 is formed to include a first guide portion 331 and a second guide portion 332 formed at different positions from each other when viewed from the insertion direction of the coaxial cable terminal 200 .

[0099] The first guide portion 331 is used to guide the outer periphery of both sides of the terminal end of the coaxial cable terminal 200 , and the second guide portion 332 is used to guide the outer periphery of the bottom of the terminal end of the coaxial cable terminal 200 .

[0100] More specifically, the first guide portion 331 may be formed to guide a portion of the upper portion, including the center, and a portion of the bottom portion of the outer periphery on both sides of the coaxial cable terminal 200. Simultaneously, the second guide portion 332 may be formed to guide the remaining portion of the bottom portion of the coaxial cable terminal 200 that is not guided by the first guide portion 331.

[0101] In particular, Figures 7 to 14As shown, the second guide portion 332 is located further back than the first guide portion 331 in the insertion direction of the coaxial cable terminal 200. Thus, based on the insertion direction of the coaxial cable terminal 200, the coaxial cable terminal 200 can sequentially pass through the first guide portion 331 and the second guide portion 332 with a time difference.

[0102] That is, Figure 17 and Figure 18 As shown, the coaxial cable terminal 200 is first guided by the first guide portion 331, and then, as shown in FIG. Figure 19 and Figure 20 As shown, it is guided by the second guide portion 332. Therefore, even if the front end of the coaxial cable terminal 200 is tilted downward by the lance 324, it will partially move upward toward the axial center in the terminal installation hole 321 while passing through the first guide portion 331, and then the bottom of the front end of the coaxial cable terminal 200 will be guided while passing through the second guide portion 332.

[0103] That is, even if the front end of the coaxial cable terminal 200 is tilted downward due to the pressure of the lance 324 during the insertion process, the problem of the end face of the coaxial cable terminal 200 being caught on the catch edge 330 and being bound can be prevented, thereby solving the difficulty of operation.

[0104] The first guide portion 331 and the second guide portion 332 forming the above-mentioned engaging ridge 330 can be separated from each other and formed separately.

[0105] However, considering that the two guide portions 331 and 332 may be deformed or damaged when guiding the front end of the coaxial cable terminal 200 if they are formed separately, it is more preferable that the first guide portion 331 and the second guide portion 332 are formed integrally with each other.

[0106] That is, preferably, the second guide portion 332 is extended from the first guide portion 331 so as to be integral with each other.

[0107] At this time, the connection portion between the second guide portion 332 and the first guide portion 331 may be formed to extend rearward from the first guide portion 331 toward the second guide portion 332 .

[0108] Next, the process of disposing the coaxial cable terminal 200 of the coaxial cable connector assembly according to the embodiment of the present invention in the connector housing 300 will be described in more detail.

[0109] First, if Figure 3As shown in FIG. 1 , a connector housing 300 and a coaxial cable 100 are prepared. At this time, the coaxial cable 100 is provided with a coaxial cable terminal 200 at the front end thereof.

[0110] Then, the coaxial cable terminal 200 of the coaxial cable 100 prepared above is installed in the connector housing 300 .

[0111] The coaxial cable terminal 200 is provided so as to extend from one end of the connector housing 300 through a terminal installation hole 321 formed in the connector housing 300. In this case, the one end of the connector housing 300 may be a terminal end forming a terminal installation portion 320 of the connector housing 300 (the end opposite to the connection portion with the connector receiving portion).

[0112] like Figure 15 and Figure 16 As shown, when the coaxial cable terminal 200 is inserted into the terminal installation hole 321 , the front end of the coaxial cable terminal 200 collides with the lance 324 of the connector housing 300 that partially protrudes into the terminal installation hole 321 .

[0113] Therefore, if Figure 17 and Figure 18 As shown, the front end of the coaxial cable terminal 200 is inclined in the direction in which the binding rib 324 a of the lance 324 protrudes (the lower direction in the figure).

[0114] Furthermore, by continuing the insertion operation, the front end of the coaxial cable terminal 200 is further moved forward in an inclined state and reaches a portion where the engaging ridge 330 is formed.

[0115] Afterwards, the outer periphery of both sides of the front end of the coaxial cable terminal 200 is guided toward the axial center in the terminal setting hole 321 by the first guide portion 331 constituting the above-mentioned engaging edge 330. That is, even if the front end of the coaxial cable terminal 200 is tilted downward due to the lance 324, a portion thereof will move upward toward the axial center in the terminal setting hole 321 while passing through the first guide portion 331. Figure 19 and Figure 20 shown.

[0116] Next, while the front end of the coaxial cable terminal 200 is guided by the first guide portion 331, the second guide portion 332 forming the engaging ridge 330 guides the outer periphery of the bottom portion toward the axial center of the terminal receiving hole 321. At this time, the front end of the coaxial cable terminal 200 is lifted upward by the first guide portion 331 while passing through the second guide portion 332, thereby preventing the front end of the coaxial cable terminal 200 from colliding with the front lower end of the second guide portion 332.

[0117] That is, since the first guide portion 331 and the second guide portion 332 forming the above-mentioned snap-fit ​​edge 330 guide the front end of the above-mentioned coaxial cable terminal 200 to be located at the axial center in the terminal setting hole 321 in a time-difference manner, the problem of the front end of the above-mentioned coaxial cable terminal 200 being prevented from tilting up and down excessively and colliding with the front of the snap-fit ​​edge 330 can be prevented.

[0118] Furthermore, as described above, since the front periphery of the coaxial cable terminal 200 is completely guided by the inclined portion formed at the front corner of the clamping edge 330, the front end of the coaxial cable terminal 200 can move smoothly along the axial center in the terminal setting hole 321.

[0119] Afterwards, when the front end of the coaxial cable terminal 200 passes through the engaging ridge 330 and reaches the connector receiving portion 310 of the connector housing 300, the step portion 211 formed on the outer periphery of the coaxial cable terminal 200 engages with the engaging ridge 330, thereby preventing further forward movement. Figure 5 and Figure 6 shown.

[0120] Furthermore, when the front surface of the stepped portion 211 of the coaxial cable terminal 200 reaches a position where it collides with the engaging ridge 330, the rear surface of the stepped portion 211 is restrained by the restraining ridge 324a of the lance 324. Thus, the coaxial cable terminal 200 can be stably maintained in this position without moving forward or backward.

[0121] Thereafter, a terminal position assurance member (TPA) (not shown) is installed in the installation groove 323 of the connector housing 300 , so that the coaxial cable terminal 200 can be kept in the installed state more stably.

[0122] As described above, according to the coaxial cable connector assembly and its connector housing of the present invention, the front end of the coaxial cable terminal 200 is guided to pass through the snap-fit ​​edge 330 of the connector housing 300 in sequence with a time difference, thereby preventing the front end bottom of the coaxial cable terminal 200 from colliding with the lower end of the snap-fit ​​edge 330 and being constrained.

[0123] In particular, the engaging ridge 330 of the connector housing 300 is formed so that the front end of the coaxial cable terminal 200 first passes through the first guide portion 331 while the movement of the outer periphery on both sides is guided, and then passes through the second guide portion 332 while the movement of the outer periphery on the bottom is guided. Thus, even if the front end of the coaxial cable terminal 200 is tilted in the vertical direction by the lance 324, the movement of the bottom is guided after the outer periphery on both sides is lifted toward the axial center during the passage through the engaging ridge 330, thereby allowing the terminal to move smoothly along the axial center of the terminal receiving hole 321.

[0124] As described above, although the embodiments of the present invention are described in such a way that all the structural elements are combined into one or act in a combined state, the present invention is not limited to such embodiments. That is, as long as it is within the scope of the purpose of the present invention, all its structural elements can be selectively combined and act in more than one manner.
