[0031] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] A coaxial connector is used to connect a coaxial cable to an electrical device. In the prior art, the coaxial connector uses unilateral positioning for the cable, which causes the cable to be skewed when in use. The coaxial connector includes a male end and a female end, which are locked and unlocked by a locking device. The cantilever of the locking device is short, the pressing stroke is large, and the fulcrum is close to the connecting end faces of the male end and the female end. After repeated use, the locking device is prone to breakage and failure.

[0033] Reference below Figure 1-Figure 6 A coaxial connector assembly according to an embodiment of the present invention is described.

[0034] According to the utility model, the coaxial connector assembly 1 includes a fixed seat 11, a terminal assembly 12 and a plug-in seat 13. A fixed channel is formed in the fixed seat 11, and a locking device is formed on the fixed seat 11; at least a part of the terminal assembly 12 is arranged in the fixed channel, and the outer periphery of the terminal assembly 12 forms a matching portion that matches with the inner wall of the fixed channel, and the matching portion radially stops against the inner wall of the fixed channel to achieve radial positioning of the terminal assembly 12; a connecting terminal 131 suitable for connecting with the terminal assembly 12 is arranged in the plug-in seat 13, and the plug-in seat 13 is suitable for connecting with the fixed seat 11, wherein a snap-in protrusion 132 that matches with the locking device is arranged on the plug-in seat 13, and the locking device can selectively lock or unlock with the snap-in protrusion 132.

[0035] Specifically, the fixing seat 11 is constructed as a female connector, and the plug-in seat 13 is constructed as a male connector. A fixing channel is formed in the fixing seat 11, and at least a portion of the terminal assembly 12 is accommodated in the fixing channel. The plug-in seat 13 is provided with a connecting terminal 131 connected to the terminal assembly 12. After the fixing seat 11 and the plug-in seat 13 are connected, the connection between the terminal assembly 12 and the connecting terminal 131 is realized, thereby realizing electrical connectivity, wherein a mating portion is formed on the outer periphery of the terminal assembly 12, and the mating portion radially stops against the inner wall of the fixing channel to fix the terminal assembly 12. The mating portion can be constructed in multiple numbers, and the multiple mating portions respectively cooperate with the inner wall of the fixing channel to ensure that the terminal assembly 12 is coaxially arranged with the fixing seat 11 in the extension direction, thereby avoiding bending of the terminal assembly 12 when connected to the connecting terminal 131 and affecting the service life. A locking device is formed on the fixed seat 11, and a snap-in protrusion 132 is provided on the plug-in seat 13. After the fixed seat 11 and the plug-in seat 13 are connected, the locking device can selectively cooperate with the snap-in protrusion 132. When the locking device is locked with the snap-in protrusion 132, the fixed seat 11 and the plug-in seat 13 are locked. When the locking device is separated from the snap-in protrusion 132, they can be unlocked. The locking and unlocking process of the fixed seat 11 and the plug-in seat 13 is simple and convenient.

[0036] According to the coaxial connector assembly 1 of the utility model, a mating portion that radially stops against the fixed channel is arranged on the outer periphery of the terminal assembly 12, thereby improving the installation stability of the terminal assembly 12, ensuring that the terminal assembly 12 and the fixed seat 11 are arranged coaxially, avoiding the plug-in seat 13 from contacting the terminal assembly 12 when connected to the fixed seat 11 and causing the terminal assembly 12 to bend, thereby ensuring the service life of the terminal assembly 12; a locking device is arranged on the fixed seat 11, and the locking device can be selectively locked with the clamping protrusion 132 on the plug-in seat 13, and the locking operation of the fixed seat 11 and the plug-in seat 13 is convenient.

[0037] According to some embodiments of the present invention, the mating portion is configured as a plurality of mating portions spaced apart in the extension direction of the terminal assembly 12 , and at least one of the plurality of mating portions abuts against both sides of the inner wall of the fixed channel in the extension direction.

[0038] Specifically, a plurality of mating portions are spaced apart in the extension direction of the terminal assembly 12, and the plurality of mating portions are respectively radially abutted against the inner wall of the fixed channel to achieve radial positioning of the terminal assembly 12, thereby ensuring that the terminal assembly 12 is coaxially arranged, and at least one mating portion is abutted against the inner wall of the fixed channel on both sides of the extension direction to achieve axial limitation of the terminal assembly 12. For example, a mating portion on the terminal assembly 12 may be abutted against the inner wall of the fixed channel on both sides of the extension direction, or there may be two or more mating portions that are respectively abutted against the inner wall of the fixed channel on both sides of the extension direction to limit the mating portions on both sides of the extension direction, thereby preventing the terminal assembly 12 from detaching from the fixed channel or excessively extending from the fixed channel in the extension direction, thereby protecting the terminal assembly 12.

[0039] According to some embodiments of the utility model, the fixed channel includes a first section 111 and a second section 112, which are arranged sequentially in the extension direction of the fixed channel, and the matching portion includes a first matching portion 121 and a second matching portion 122, the first matching portion 121 abuts against the inner wall of the first section 111, and the second matching portion 122 abuts against the inner wall of the second section 112.

[0040] like Figures 3 to 5 As shown, the first section 111 and the second section 112 are arranged in sequence in the extension direction of the fixed channel. After the terminal assembly 12 is extended into the fixed channel, the first matching portion 121 radially stops against the inner wall of the first section 111, and the second matching portion 122 radially stops against the inner wall of the second section 112, thereby ensuring that the terminal assembly 12 extended into the fixed channel remains coaxial with the fixed terminal, avoiding the terminal assembly 12 from being skewed due to external force when being connected to the connecting terminal 131, thereby ensuring the safe use of the terminal assembly 12.

[0041] An open opening is formed at one end of the first section 111 and opens toward the socket 13. The terminal assembly 12 is accommodated in the first section 111. A protective distance is reserved between one end of the terminal assembly 12 and the open opening. During the connection between the fixed seat 11 and the socket 13, the socket 13 will not contact the fixed terminal, thereby avoiding damage to the terminal assembly 12 due to the oblique insertion of the socket 13.

[0042] According to some embodiments of the present invention, the diameter of the first section 111 is smaller than the diameter of the second section 112, and a step surface 113 is formed between the first section 111 and the second section 112, which is opposite to the second matching portion 122, and the step surface 113 abuts against one side of the first matching portion 121 in the extension direction.

[0043] like Figure 3 and Figure 5As shown, the diameter of the first section 111 is smaller than the diameter of the second section 112, so as to define a step surface 113 between the first section 111 and the second section 112, and the step surface 113 is opposite to the second matching portion 122 on one side of the extension direction. When the terminal assembly 12 is installed in the fixed channel, as the terminal assembly 12 moves, the second matching portion 122 moves to stop with the step surface 113, so as to limit the terminal assembly 12 in the forward direction of the terminal assembly 12, avoid excessive extension of the terminal assembly 12, and accommodate the end of the terminal assembly 12 inside the first section 111 to protect the terminal assembly 12.

[0044] According to some embodiments of the utility model, the fixing channel is formed with a clamping arm 114, and the clamping arm 114 is arranged in the second section 112. The end of the clamping arm 114 is spaced apart from the first section 111 to form a receiving hole for accommodating the second matching portion 122. The end of the clamping arm 114 abuts against the other side of the second matching portion 122 in the extension direction.

[0045] like Figure 3 and Figure 5 As shown, a clamping arm 114 is provided on the second section 112, and the clamping arm 114 is elastically connected to the fixing seat 11, and a receiving hole is formed between the end of the clamping arm 114 and the first section 111. When the second matching portion 122 moves into the receiving hole, the end of the clamping arm 114 and the second matching portion 122 stop on the other side of the extension direction to limit the terminal assembly 12 from moving toward the other side of the extension direction to prevent the terminal assembly 12 from detaching from the fixing seat 11. By forming a step surface 113 and a receiving hole in the fixing channel, the step surface 113 and the receiving hole respectively limit the two sides of the extension direction of the second matching portion 122 to achieve axial positioning of the terminal assembly 12. At the same time, due to the blocking of the terminal assembly 12 by the step surface 113, the terminal assembly 12 will not extend out of the first section 111 too much, and the terminal assembly 12 is safely received in the fixing channel to protect the terminal assembly 12.

[0046] According to some embodiments of the present invention, the coaxial connector assembly 1 also includes a clamping portion 115, which is suitable for clamping with the outer periphery of the fixing seat 11 and covering the side of the clamping wall away from the terminal assembly 12, and at least a portion of the clamping portion 115 extends into the receiving hole and stops with the second mating portion 122.

[0047] Specifically, when the terminal assembly 12 is mated with the fixed channel, the clamping portion 115 is clamped with the outer periphery of the fixing seat 11 and covered on the side of the clamping arm 114 away from the terminal assembly 12, and at least part of the clamping portion 115 extends into the receiving hole. The clamping portion 115 and the clamping arm 114 are arranged to jointly support the terminal assembly 12. At the same time, the inner wall of the first section 111 is stopped against the first mating portion 121 to achieve radial positioning of the terminal assembly 12, thereby ensuring that the terminal assembly 12 is coaxially arranged with the fixing seat 11 and avoiding the terminal assembly 12 from being skewed.

[0048] According to some embodiments of the utility model, the locking device includes a pressing arm 141 and a locking arm 142, the pressing arm 141 and the locking arm 142 are connected, and a locking hole 1421 suitable for locking with the clamping protrusion 132 is formed on the locking arm 142; a connecting portion 143, and the connecting portion 143 is arranged between the locking arm 142 and the fixed seat 11, wherein pressing down the pressing arm 141 can drive the locking arm 142 to move relative to the connecting portion 143 to lock or unlock the locking hole 1421 and the clamping protrusion 132.

[0049] Specifically, the pressing arm 141 and the locking arm 142 are connected to the fixing seat 11 through the connecting portion 143, and the pressing arm 141 and the locking arm 142 can move relative to the connecting portion 143. When the locking device is not engaged with the engaging protrusion 132, the distance between the pressing arm 141 and the fixing seat 11 is greater than the distance between the locking arm 142 and the fixing seat 11. As the plug-in seat 13 is connected to the fixing seat 11, the engaging protrusion 132 on the plug-in seat 13 moves toward the locking arm 142. The locking arm 142 is lifted by the latching protrusion 132 and moves it into the locking hole 1421. The locking arm 142 falls down again and locks the latching protrusion 132. When the connector 13 and the fixing base 11 need to be unlocked, the pressing arm 141 is pressed down to lift the locking arm 142. The latching protrusion 132 is disengaged from the locking hole 1421. The connector 13 is pulled out, and the fixing base 11 and the connector 13 can be separated. The locking and unlocking operations of the connector 13 and the fixing base 11 are simple and convenient.

[0050] According to some embodiments of the present invention, the length of the locking arm 142 is greater than that of the pressing arm 141. By increasing the length of the locking arm 142 and shortening the length of the pressing arm 141, the stroke of the pressing portion during the unlocking process is reduced. When unlocking, the force applied by pressing the pressing arm 141 and the angle moved by the locking arm 142 are reduced, making locking and unlocking of the locking device more convenient. Moreover, since the strokes of the pressing arm 141 and the locking arm 142 are reduced, locking and unlocking cause less loss to the locking device, which is beneficial to extending the service life of the locking device.

[0051] According to some embodiments of the present invention, a blind hole 116 is provided on the fixing seat 11 , the blind hole 116 is opposite to the connecting portion 143 , and a support plate 117 is provided between the blind hole 116 and the connecting portion 143 , and the thickness of the support plate 117 is less than the thickness of the connecting portion 143 .

[0052] Specifically, during the movement of the pressing arm 141 and the locking arm 142 relative to the connecting portion 143, the stress is concentrated on the connecting portion 143. Long-term use of the locking device will make the connecting portion 143 vulnerable to damage, affecting the service life of the locking device. Therefore, a blind hole 116 is provided on the fixing seat 11, which is opposite to the connecting portion 143, and a support plate 117 is provided between the blind hole 116 and the connecting portion 143. The thickness of the support plate 117 is constructed to be smaller than the thickness of the connecting portion 143, so that the stress is dispersed to the support plate 117, thereby reducing the damage to the connecting portion 143 caused by the locking device during the locking and unlocking process, extending the service life of the locking device, and ensuring that the fixing seat 11 and the plug-in seat 13 are stably connected.

[0053] In some embodiments, a support beam 118 is arranged between the support plate 117 and the blind hole 116, and the support beam 118 is arranged in the middle position of the blind hole 116. Since the manufacturing process of the fixing seat 11 is plastic injection molding, by arranging the support beam 118 in the middle of the blind hole 116, the mold flow channel between the locking device and the fixing seat 11 can be enlarged, thereby improving the injection molding quality.

[0055] According to the utility model, the vehicle has the coaxial connector assembly 1 described in any one of the above-mentioned embodiments. Since the vehicle according to the utility model has the coaxial connector assembly 1 described in any one of the above-mentioned embodiments, the coaxial connector assembly 1 in the vehicle supports the terminal assembly 12 more stably, the use of the terminal assembly 12 is safer, and the locking device of the coaxial connector assembly 1 has a longer service life, thereby reducing the maintenance cost of vehicle parts.
