Abstract
Description
Technical Field
[0001] The present invention relates to an electrical connector device, and more particularly to a connector and a connector assembly using the connector. Background Art
[0002] When performing grounding or shielding design on a chassis or a cabinet, it is necessary to conduct the connector at the interface of the chassis or cabinet with the chassis or cabinet panel to achieve conduction between the shielding layer of the cable connected by the connector and the panel, so as to achieve the grounding or shielding effect of the overall link.
[0003] As Figure 1 shown, in the prior art, a crimping clip 103 is used to connect a cable 102 to a connector. Specifically, the connector includes a conductive housing and an insulating member 101, and there are conductive contact members inside the insulating member 101. The front end of the cable 102 is stripped to expose the cable core, and the shielding layer is exposed by stripping the cable core at the rear. The exposed cable core is inserted into the insulating member 101, and the cable core is conductively connected to the conductive contact member, and the cable core is locked in the insulating member 101 by a locking mechanism inside the insulating member. A crimping clip 103 is provided outside the shielding layer. The structure of the crimping clip 103 is as Figure 2 shown. The crimping clip 103 includes a shielding lower pressing plate 1031, a locking piece 1032, and a locking screw 1033. The part of the cable 102 where the shielding layer is exposed is placed between the shielding lower pressing plate 1031 and the locking piece 1032, and is pressed and fixed by the locking screw 1033. The shielding lower pressing plate 1031 is a conductor and is conductively connected to the conductive housing of the connector. The shielding layer is conductively connected to the conductive housing through the crimping clip 103, and then is effectively conductively connected to the panel through the conductive housing.
[0004] This crimping and shielding method in the prior art has some drawbacks: using the method of clamping up and down and locking with a locking screw to fix the shielding layer of the cable requires screwing the locking screw during use, resulting in inconvenient operation and complex wire making. Summary of the Invention
[0005] The purpose of the present invention is to provide a connector to solve the technical problems of inconvenient operation and complex wire making caused by using a screw locking method to fix the cable in the prior art; and also provide a connector assembly using the connector to solve the above technical problems.
[0006] To achieve the above purpose, the technical solution of the connector of the present invention is: a connector, including:
[0007] A conductive front housing, inside which there are contact members for connecting to the cable core of the cable;
[0008] An outer sleeve for connecting to the rear end of the conductive front housing;
[0009] The conductive sleeve extends forward and backward, and is provided with a wire threading channel for the cable to pass through. The outer sleeve is rotatably sleeved outside the conductive sleeve.
[0010] A conductive member is arranged in the wire threading channel of the conductive sleeve. In the radial direction of the conductive sleeve, the outer end of the conductive member is used for electrically contacting the conductive sleeve, and the inner end is used for electrically contacting the shielding layer of the cable when the cable passes through the wire threading channel.
[0011] A pressing portion is arranged in the outer sleeve. The pressing portion is used for pushing the conductive sleeve forward so that the conductive sleeve is in electrical contact with the conductive front housing.
[0012] The beneficial effects of the present invention are as follows: The shielding layer is connected to the conductive sleeve through the conductive member. The outer sleeve is connected to the conductive front housing. The pressing portion arranged on the outer sleeve presses the conductive sleeve against the conductive front housing, realizing a complete shielding link of the shielding layer, the conductive member, the conductive sleeve, and the conductive front housing. In the present invention, a wire threading channel is arranged in the conductive sleeve and a conductive member is arranged in the wire threading channel to realize the connection between the shielding layer of the cable and the conductive front housing, without the need to screw the screw, making the wire making more convenient. In the present invention, the conductive sleeve and the outer sleeve can rotate relative to each other. During the process of the outer sleeve being rotatably connected to the conductive front housing or rotating to adjust the position, the conductive sleeve, the conductive member, and the cable do not rotate relative to each other, preventing the conductive member from squeezing and damaging the cable when the conductive member and the cable rotate relative to each other and destroying the shielding layer of the cable, thereby ensuring the reliability of the shielding grounding.
[0013] As a further optimized solution, the conductive member is an elastic conductive member. The inner end of the elastic conductive member can be elastically deformed. When the shielding layer of the cable passes through the elastic conductive member, the inner end of the elastic conductive member is pressed and deformed by the shielding layer and is in electrical contact with the shielding layer.
[0014] The effect of this solution is that the conductive member is an elastic conductive member, and its inner end can be elastically deformed. After being pressed and deformed by the shielding layer, it can apply an elastic force to the shielding layer, and the electrical contact is more reliable.
[0015] As a further optimized solution, the elastic conductive member is an annular conductive member movably assembled in the conductive sleeve;
[0016] A positioning structure for positioning the annular conductive member back and forth is arranged on the inner wall of the conductive sleeve.
[0017] The effect of this solution is that the annular conductive member is movably assembled in the conductive sleeve, which can realize separate processing and then assembly, and the processing is relatively convenient. The positioning structure can also ensure that the annular conductive member does not move. By using the annular conductive member to press the shielding layer of the cable, the shielding layer is uniformly stressed circumferentially, avoiding being crushed due to excessive local pressure.
[0018] As a further optimized solution, the annular conductive member is an annular conductive spring formed by connecting the spring wires end to end. The positioning structure is an annular positioning groove provided on the inner wall of the conductive sleeve, and the conductive spring is adaptively assembled in the annular positioning groove.
[0019] The effect of this solution is that the positioning structure is an annular positioning groove, which is convenient to process. The annular conductive member is a conductive spring and can be installed in the annular positioning groove.
[0020] As a further optimized solution, the annular positioning groove is a constricted structure to prevent the conductive spring from radially disengaging from the annular positioning groove.
[0021] The effect of this solution is that the annular positioning groove is a constricted structure, which can prevent the conductive spring from disengaging from the annular positioning groove.
[0022] As a further optimized solution, the pressing part is fixedly arranged in the outer sleeve. When the outer sleeve moves forward and is assembled on the conductive front housing, the pressing part moves forward with the outer sleeve to push the conductive sleeve.
[0023] The effect of this solution is that the pressing part is fixedly arranged in the outer sleeve and pushes the conductive sleeve as the outer sleeve moves, which is convenient to use.
[0024] As a further optimized solution, the pressing part is an inner step integrally formed in the outer sleeve.
[0025] As a further optimized solution, an anti-disengagement limiting part is provided at the front end of the outer sleeve. The anti-disengagement limiting part is used for blocking and cooperating with the front end of the conductive sleeve to prevent the conductive sleeve from being driven to move forward and disengage from the outer sleeve when a cable is inserted into the conductive sleeve.
[0026] The effect of this solution is that the anti-disengagement limiting part can prevent the conductive sleeve from disengaging, playing a temporary limiting role for the conductive sleeve. When the outer sleeve is installed between the conductive front housings, a pre-assembled unit of the conductive sleeve, cable, and outer sleeve can be formed.
[0027] As a further optimized solution, the part of the conductive sleeve for making conductive contact with the conductive front housing is the front end face;
[0028] The anti-disengagement limiting part is used for blocking and cooperating with the front end face of the conductive sleeve to prevent the conductive sleeve from moving forward and disengaging;
[0029] A relief annular groove for accommodating the anti-disengagement limiting part is provided outside the rear end of the conductive front housing.
[0030] The effect of this solution is that the conductive sleeve is in conductive contact with the conductive front housing through the front end face, and the front end structure of the conductive sleeve is relatively simple.
[0031] The technical solution of the connector assembly of the present invention is as follows: A connector assembly includes:
[0032] A connector for docking and connecting with an adapter connector;
[0033] The connector includes:
[0034] A conductive front housing with contacts disposed therein, and the contacts are connected to the cable cores;
[0035] An outer sleeve for connecting to the rear end of the conductive front housing;
[0036] A conductive sleeve extending forward and backward, with a threading channel for the cable to pass through provided therein, and the outer sleeve is rotatably sleeved outside the conductive sleeve;
[0037] A conductive member is provided in the threading channel of the conductive sleeve. In the radial direction of the conductive sleeve, the outer end of the conductive member is used for conductive contact with the conductive sleeve, and the inner end is used for conductive contact with the shielding layer of the cable when the cable penetrates into the threading channel;
[0038] A tightening portion is provided in the outer sleeve, and the tightening portion is used to push the conductive sleeve forward to make conductive contact between the conductive sleeve and the conductive front housing.
[0039] A cable includes a core and a shielding layer. The cable penetrates into the conductive sleeve and extends forward. Its core is connected to the contacts of the connector, and the shielding layer of the cable makes conductive contact with the conductive member.
[0040] The beneficial effects of the present invention are as follows: The shielding layer is connected to the conductive sleeve through the conductive member. The outer sleeve is connected to the conductive front housing. The tightening portion provided on the outer sleeve presses the conductive sleeve against the conductive front housing, realizing a complete shielding link of the shielding layer, the conductive member, the conductive sleeve, and the conductive front housing. In the present invention, the way of setting a threading channel in the conductive sleeve and a conductive member in the threading channel is adopted to realize the connection between the shielding layer of the cable and the conductive front housing, without the need to screw in screws, making wire making more convenient. In the present invention, the conductive sleeve and the outer sleeve can rotate relative to each other. During the process of the outer sleeve being rotatably connected to or rotatably adjusting the position of the conductive front housing, the conductive sleeve, the conductive member, and the cable do not rotate relative to each other, preventing the conductive member from squeezing and damaging the cable when the conductive member and the cable rotate relative to each other and destroying the shielding layer of the cable, thereby ensuring the reliability of shielding grounding.
[0041] As a further optimized solution, the conductive member is an elastic conductive member. The inner end of the elastic conductive member can be elastically deformed. When the shielding layer of the cable penetrates to the elastic conductive member, the inner end of the elastic conductive member is pressed and deformed by the shielding layer and makes conductive contact with the shielding layer.
[0042] The effect of this solution is that the conductive part is an elastic conductive part, and its inner end can undergo elastic deformation. After being pressed and deformed by the shielding layer, it can exert an elastic force on the shielding layer, making the conductive contact more reliable.
[0043] As a further optimized solution, the elastic conductive part is an annular conductive part movably assembled in the conductive sleeve;
[0044] A positioning structure for front-back positioning of the annular conductive part is provided on the inner wall of the conductive sleeve.
[0045] The effect of this solution is that the annular conductive part is movably assembled in the conductive sleeve, which can achieve separate processing and then assembly, making the processing more convenient. And the positioning structure can also ensure that the annular conductive part will not move around. By using the annular conductive part to compress the shielding layer of the cable, the shielding layer is uniformly stressed circumferentially, avoiding being crushed due to excessive local pressure.
[0046] As a further optimized solution, the annular conductive part is an annular conductive spring formed by connecting the spring wires end to end. The positioning structure is an annular positioning groove provided on the inner wall of the conductive sleeve, and the conductive spring is fitted in the annular positioning groove.
[0047] The effect of this solution is that the positioning structure is an annular positioning groove, which is convenient to process. The annular conductive part is a conductive spring and can be installed in the annular positioning groove.
[0048] As a further optimized solution, the annular positioning groove is a necking structure to prevent the conductive spring from radially disengaging from the annular positioning groove.
[0049] The effect of this solution is that the annular positioning groove is a necking structure, which can prevent the conductive spring from disengaging from the annular positioning groove.
[0050] As a further optimized solution, the pressing part is fixedly arranged in the outer sleeve. When the outer sleeve is movably assembled forward on the conductive front housing, the pressing part moves forward with the outer sleeve to push the conductive sleeve.
[0051] The effect of this solution is that the pressing part is fixedly arranged in the outer sleeve and pushes the conductive sleeve as the outer sleeve moves, which is convenient to use.
[0052] As a further optimized solution, the pressing part is an inner step integrally formed in the outer sleeve.
[0053] As a further optimized solution, an anti-disengagement limiting part is provided at the front end of the outer sleeve. The anti-disengagement limiting part is used for stop cooperation with the front end of the conductive sleeve to prevent the conductive sleeve from being driven to move forward and disengage from the outer sleeve when a cable is inserted into the conductive sleeve.
[0054] The effect of this solution is that the anti-dropping limiter can prevent the conductive sleeve from falling out, and temporarily limit the conductive sleeve. When the outer sleeve is installed between the conductive front shell body, a pre-installed unit of the conductive sleeve, cable and outer sleeve can be formed.
[0055] As a further optimized solution, the portion of the conductive sleeve used for conductive contact with the conductive front housing is the front end surface;
[0056] The anti-dropping limiter is used to cooperate with the front end surface of the conductive sleeve to prevent the conductive sleeve from falling out forward;
[0057] An escape ring groove for accommodating the anti-dropping limiting member is provided on the outside of the rear end of the conductive front shell.
[0058] The effect of this solution is that the conductive sleeve is in contact and conduction with the conductive front shell through the front end surface, and the front end structure of the conductive sleeve is relatively simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0075] The features and performance of the present invention will be further described in detail below in conjunction with embodiments.
[0076] Specific Embodiment 1 of the connector assembly of the present invention:
[0077] As Figures 3 to 6 shown, the connector assembly includes a connector 200 and a cable 500. The connector 200 is used to dock and communicate with an adapter connector 400. The adapter connector 400 may specifically be an adapter connector 400 fixed on a cabinet. The front end of the cable 500 is inserted into the connector 200.
[0078] As Figures 3 to 5 shown, the connector 200 extends longitudinally from front to back as a whole. The end for docking with the adapter connector 400 is the front end. The connector 200 includes a split conductive front housing 201 and an outer sleeve 203. The outer sleeve 203 is located at the rear side of the conductive front housing 201. The front end of the outer sleeve 203 is provided with an internal thread. The conductive front housing 201 and the outer sleeve 203 are detachably fixedly assembled through threaded connection.
[0079] An insulator 202 is fixedly arranged inside the conductive front housing 201. A contact (not shown in the figure) is fixedly arranged inside the insulator 202. A locking structure is provided on the insulator to fix the cable core penetrating into the insulator 202. Here, the locking structure is a crimping screw, and the crimping screw is threadedly assembled on the insulator or the contact to fix the cable core and the contact together to achieve electrical conduction or signal connection. As Figure 3 can be seen, after the conductive front housing 201 and the outer sleeve 203 are assembled, there is a radial gap between the outer sleeve 203 and the insulator 202. This gap is for the conductive sleeve 204 to penetrate, so that the front end of the conductive sleeve 204 can be in conductive contact with the conductive front housing 201.
[0080] Inside the outer sleeve 203, a conductive sleeve 204 is sleeved. The conductive sleeve 204 is a conductive part, and the outer sleeve 203 is sleeved outside the conductive sleeve 204. There is an interval fit between the outer sleeve 203 and the conductive sleeve 204, and the two can rotate freely relative to each other. The structure of the conductive sleeve 204 is as shown in Figure 4 shown. There is a wire threading channel for the cable to pass through inside the conductive sleeve 204. An elastic conductive part is fixed in the wire threading channel, and the elastic conductive part is conducted with the conductive sleeve 204. When the shielding layer 501 penetrates to the elastic conductive part, the elastic conductive part is pressed against the shielding layer 501 to realize the conduction between the shielding layer 501 and the conductive sleeve 204. To make the force on each part of the shielding layer 501 uniform, preferably, the elastic conductive part is an annular conductive part, which applies a circumferentially evenly distributed pressing force to the shielding layer 501.
[0081] The annular conductive part here is an annular conductive spring 205. Specifically, an annular positioning groove 2041 is provided on the inner wall of the conductive sleeve 204, and the annular positioning groove 2041 extends along the circumference of the conductive sleeve 204. The conductive spring 205 is positioned and assembled in the annular positioning groove 2041. The conductive spring 205 is a conductive part, and the conductive spring 205 here is formed by connecting the head and tail of a section of spring wire.
[0082] The conductive spring 205 is a triangular spring with a triangular cross-section. There is a channel for the cable 500 to pass through in the middle of the conductive spring 205. When the cable 500 penetrates into the conductive spring 205, the inner diameter of the conductive spring 205 is expanded. The inner diameter contact part of the conductive spring 205 is pressed against the shielding layer 501 of the cable 500, and the outer diameter contact part is pressed against the bottom of the annular positioning groove 2041 of the conductive sleeve 204. In fact, the conductive spring 205 in this embodiment is a prior art, and reference can be made to the conductive spring ring in the Chinese patent application with the application publication number CN111628355A. In this embodiment, as shown in Figure 4 shown, in order to further prevent the conductive spring 205 from slipping out of the annular positioning groove 2041 when the cable 500 penetrates into the conductive spring 205, the annular positioning groove 2041 is a closed structure with both ends closed to limit the conductive spring 205.
[0083] As shown in Figure 4As shown in the figure, during assembly, the conductive sleeve 204 is inserted into the front end of the outer sleeve 203. An inner step 2031 is integrally formed at a position near the rear of the outer sleeve 203, which can push against the conductive sleeve 204. During assembly, the conductive spring 205 is first assembled into the conductive sleeve 204, and then the conductive sleeve 204 with the conductive spring 205 is inserted into the outer sleeve 203, and then the cable 500 is inserted forward. In this embodiment, in order to prevent the conductive sleeve 204 from being driven forward by the cable 500 and disengaging from the outer sleeve 203 when inserting the cable 500, an anti-disengagement stop is installed on the front part of the inner wall of the outer sleeve 203. Through the blocking cooperation between the anti-disengagement stop and the conductive sleeve 204, the conductive sleeve 204 is prevented from disengaging. The anti-disengagement stop here is a snap ring 206, and the snap ring 206 is installed in the annular groove of the outer sleeve 203. After the conductive sleeve 204 is inserted into the set position of the outer sleeve 203, the snap ring 206 is installed at the annular groove to prevent the conductive sleeve 204 from disengaging. It should be noted that the snap ring 206 here serves to prevent the conductive sleeve 204 from disengaging, rather than positioning the conductive sleeve 204. When inserting the cable 500, the conductive sleeve 204 can have a certain amount of movement in the front-rear direction.
[0084] In this embodiment, as Figure 3 shown, the conductive sleeve 204 is electrically connected by tightly contacting its front end face with the conductive front housing 201. To accommodate the snap ring 206, an avoidance annular groove 2011 is provided at the rear end of the conductive front housing 201.
[0085] During the assembly of the present invention, the conductive spring 205 is first positioned and assembled into the conductive sleeve 204, then the conductive sleeve 204 is inserted into the outer sleeve 203, and then the snap ring 206 is installed. As Figure 6 shown, when the connector 200 is connected to the cable 500, the inner diameter of the conductive spring 205 is expanded, the inner diameter contact part is pressed against the shielding layer 501 of the cable 500, and the outer diameter contact part is pressed against the inner wall of the conductive sleeve 204. The connection and conduction between the shielding layer 501 and the conductive sleeve 204 are realized through the conductive spring 205. The outer sleeve 203 is screwed onto the conductive front housing 201 by means of threaded connection. Since there is an interval fit between the conductive sleeve 204 and the outer sleeve 203 and they can rotate relative to each other, the conductive sleeve 204 will not rotate with the outer sleeve 203. Since the conductive sleeve 204 does not rotate, the cable 500 and the conductive sleeve 204 will not rotate relative to each other, effectively protecting the shielding layer 501 and preventing the shielding layer 501 from being damaged when the conductive spring 205 is prone to rotate and squeeze the shielding layer 501 when the conductive sleeve 204 rotates relative to the cable 500. After the outer sleeve 203 rotates into place, its inner step 2031 presses the conductive sleeve 204 against the conductive front housing 201, realizing the shielding conduction from the shielding layer 501 to the conductive front housing 201. The cable core of the cable 500 is inserted into the insulator 202 and fixed.
[0086] When docking the connector 200 with the adapter connector 400, the conductive front housing 201 contacts the conductive housing 401 of the adapter connector, and the conductive housing 401 of the adapter connector is connected to the chassis panel 300, forming a Figure 5 and Figure 6 shielding link as shown by the arrow in the figure.
[0087] In this embodiment, since the outer sleeve 203 and the conductive sleeve 204 can rotate relative to each other, when the outer sleeve 203 is threadedly assembled with the conductive front housing 201, the conductive sleeve 204 and the cable 500 will not rotate relative to each other, preventing the conductive sleeve 204, the conductive spring 205 and the cable 500 from rotating relative to each other, and avoiding the damage or dispersion of the shielding layer 501 (generally, the shielding layer 501 is a braided shielding layer) when the conductive spring 205 and the shielding layer 501 rotate relative to each other, and will not affect the shielding conduction performance. Moreover, when the outer sleeve 203 is rotated in the reverse direction and unscrewed from the conductive front housing 201, the conductive spring 205 and the cable 500 do not rotate relative to each other, and also prevent the cable 500 from generating resistance to the disassembly of the outer sleeve 203. Moreover, the installation state of the conductive spring 205 in the conductive sleeve 204 can be not limited, and it can be arranged obliquely or in a vertical state extending radially.
[0088] In this embodiment, the outer sleeve 203 does not play a conductive role during use. Therefore, the material of the outer sleeve 203 can be not required, and it can be a conductive material or a non-conductive material. During actual production, a plastic material with low price can be selected.
[0089] In this embodiment, the annular positioning groove 2041 in the conductive sleeve 204 functions to position the conductive spring 205 front and back, and the annular positioning groove 2041 forms a positioning structure.
[0090] In this embodiment, the main function of the inner step 2031 on the outer sleeve 203 during use is to move forward with the outer sleeve 203 and press the conductive sleeve 204 tightly against the conductive front housing 201, and the inner step 2031 forms a pressing part that can press the conductive sleeve 204 tightly.
[0091] It should be noted that the cross-section of the conductive spring in this embodiment is triangular. Actually, conductive springs with other cross-sections can also be applied in the present invention, such as spring fingers often used in the conductive field.
[0092] Specific Embodiment 2 of the Connector of the Present Invention:
[0093] In Embodiment 1, the annular positioning groove is a closed structure to prevent the conductive spring from coming out. In this embodiment, the annular positioning groove can be a rectangular groove or a V-shaped groove, and the notch can no longer be in the closed form.
[0094] Specific Embodiment 3 of the Connector of the Present Invention:
[0095] In Embodiment 1, the annular conductive member is a conductive spring, which is formed by connecting the head and tail of a single wire. In this embodiment, the annular conductive member can be a crown spring, which includes a plurality of inwardly protruding elastic bands. When the shielding layer of the cable passes through the crown spring, the crown spring clamps the shielding layer. Alternatively, the annular conductive member includes a plurality of elastic conductive clips distributed in a circle along the circumferential direction, and the shielding layer is clamped by the elastic conductive clips.
[0096] Specific Embodiment 4 of the Connector of the Present Invention:
[0097] In Embodiment 1, the elastic conductive member is an annular conductive member, which can apply a circumferentially uniform clamping force to the shielding layer. In this embodiment, the elastic conductive member may no longer be an annular conductive member. For example, the elastic conductive member only includes an elastic conductive clip, the outer end of which is fixed on the conductive sleeve, and the inner end can swing elastically. When the shielding layer passes through the elastic conductive clip, the elastic conductive clip swings elastically and presses the shielding layer against the inner wall of the conductive sleeve, and electrical connection can also be achieved.
[0098] Specific Embodiment 5 of the Connector of the Present Invention:
[0099] In Embodiment 1, the positioning structure in the conductive sleeve is an annular positioning groove. In this embodiment, the positioning structure can be a threaded sleeve detachably installed in the conductive sleeve, and the annular conductive member is positioned by two threaded sleeves.
[0100] Specific Embodiment 6 of the Connector of the Present Invention:
[0101] In Embodiment 1, the conductive sleeve is in contact and conducts electricity with the conductive front housing through its front end face, and the anti-disengagement limiting member is in a stop fit with the front end face of the conductive sleeve. To accommodate the anti-disengagement limiting member, an avoidance annular groove is provided on the conductive front housing. In this embodiment, the front end of the conductive sleeve can be stepped, with a forward step, and the anti-disengagement limiting member is in a stop fit with the step. At this time, the avoidance annular groove may no longer be provided on the conductive front housing.
[0102] Specific Embodiment 7 of the Connector of the Present Invention:
[0103] In Embodiment 1, the anti-disengagement limiting member on the outer sleeve is a snap ring. In this embodiment, the anti-disengagement limiting member can be a threaded sleeve, which is threadedly assembled in the outer sleeve to limit and stop the conductive sleeve.
[0104] Specific Embodiment 8 of the Connector of the Present Invention:
[0105] In Example 1, the tightening portion is an inner step integrally formed in the outer sleeve. In this embodiment, the tightening portion can be welded separately from the outer sleeve. Alternatively, in other embodiments, the tightening portion can be a structure such as a threaded sleeve, which is assembled on the outer sleeve in a detachable manner. When the tightening portion is detachable, during specific operations, the tightening portion can move forward with the outer sleeve, or it can be moved forward to tighten the conductive sleeve alone after the outer sleeve is installed in place.
[0106] It should be noted that when the tightening part is detachably mounted on the outer sleeve, the conductive sleeve can be inserted into the outer sleeve from the rear of the outer sleeve, so that the anti-dropping limiter at the front end of the outer sleeve can be fixed on the outer sleeve, such as an inner step.
[0107] Specific embodiment 9 of the connector of the present invention:
[0108] In Example 1, an anti-dropout stopper is provided at the front end of the outer sleeve to prevent the conductive sleeve from falling out. In this embodiment, the anti-dropout stopper can be eliminated. During assembly, the outer sleeve and the conductive sleeve can be installed to the set position of the conductive front housing first, and then the cable can be installed. At this time, since the front end of the conductive sleeve is already tightly pressed against the conductive front housing, there is no need to consider the problem of the conductive sleeve falling out.
[0109] Specific embodiment 10 of the connector of the present invention:
[0110] In Example 1, the outer sleeve is assembled on the conductive front housing by threaded connection. Since the outer sleeve and the conductive sleeve can rotate relative to each other, the conductive sleeve will not rotate with the outer sleeve. In this embodiment, the outer sleeve can be assembled on the conductive front housing by hooking. At this time, although the outer sleeve does not need to be rotated when connected to the conductive front housing, the outer sleeve can be rotated alone to adjust the position during the rotation adjustment process, which is also more convenient to use.
[0111] Specific embodiment 11 of the connector of the present invention:
[0112] In Example 1, the conductive contact with the shielding layer is ensured by the elastic deformation of the inner end of the elastic conductive member. In this embodiment, the conductive member can be a rigid structure, and the conductive member can be a conductive ring, or a conductive block or other structure, which is fixed on the inner wall of the conductive sleeve, and the outer end is in conductive contact with the conductive sleeve. When the cable is inserted into the threading channel, the inner end of the conductive member is in conductive contact with the shielding layer, so as to realize the conduction of the entire shielding link of the cable shielding layer, the conductive member and the conductive sleeve.
[0113] Specific embodiments of the connector assembly of the present invention:
[0114] The connector assembly includes a connector and a cable. The cable includes a core and a shielding layer. The structure of the connector is the same as that in the embodiments of the above-mentioned connectors, and will not be described in detail here. The core is connected to the contact in the connector, and the shielding layer is in conductive contact with the conductive member.
[0115] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. The patent protection scope of the present invention is subject to the claims. All equivalent structural changes made by using the content of the specification and drawings of the present invention should be included in the protection scope of the present invention by the same token.
