A type of wire connector

Abstract

This utility model discloses a wire-end connector, comprising: a housing and multiple power terminals and multiple signal terminals inserted into the housing. For each signal terminal, a corresponding anti-retraction structure is provided in the signal terminal insertion hole of the housing. It also includes a terminal position guarantee member inserted into the housing and cooperating with the multiple signal terminals. The insertion end of the terminal position guarantee member has a blocking member that can abut against the insulation of each signal terminal. Limiting members are provided on both sides of the terminal position guarantee member that can cooperate with the housing to limit the terminal position guarantee member within the housing. By using the blocking members to abut against the front end of the insulation of each signal terminal, the signal terminals can be further locked in the housing, increasing the holding force between the signal terminals and the housing, thereby reducing the risk of the signal terminals retracting from the housing and failing, and thus improving the stability and firmness of the signal terminals within the housing.

Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a wire-end connector. Background Technology

[0002] Existing wire connectors consist of four parts: a housing, power terminals, signal terminals, and a cable. They have the functions of transmitting current and transmitting signals. The power terminals and signal terminals clamp the cable, and then the anti-removal structure on the signal terminals, through the barbs on the signal terminals and the mounting base on the housing, forms an interference fit, thereby preventing the signal terminals from coming out of the housing.

[0003] However, in existing wire connectors, after the barbs of the signal crimp terminal are inserted into the housing, the barbs on the signal crimp terminal will first pass through the mounting platform of the housing, causing the mounting platform to undergo a certain yielding deformation inward on the barbs. This results in a smaller interference between the barbs and the mounting platform of the housing, which in turn reduces the holding force between the signal crimp terminal and the housing. This makes it easier for the signal crimp terminal to come out of the housing and fail. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wire end connector.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: A wire-end connector is constructed, comprising: a housing and multiple power supply terminals and multiple signal terminals inserted into the housing; for each signal terminal, a corresponding anti-retraction structure is provided in the signal terminal insertion hole of the housing; it also includes a terminal position guaranteeing member inserted into the housing and cooperating with the multiple signal terminals; the insertion end of the terminal position guaranteeing member is provided with a blocking member that can respectively abut against the insulation of each signal terminal; and limiting members are provided on both sides of the terminal position guaranteeing member that can cooperate with the housing to limit the terminal position guaranteeing member within the housing.

[0006] Furthermore, the limiting component includes an elastic element and a buckle. A limiting groove is provided on the rubber shell. The elastic element is disposed on the terminal position guarantee component. The buckle is disposed on the elastic element. After the terminal position guarantee component enters the rubber shell, the elastic element drives the buckle into the limiting groove.

[0007] Furthermore, the end of the elastic element moves further away from the buckle and closer to the terminal position guarantee until it comes into contact with the terminal position guarantee.

[0008] Furthermore, the buckle has an inclined surface on the side near the housing that slopes toward the terminal position guarantee.

[0009] Furthermore, the blocking member includes a connecting portion and a plurality of blocking portions. The connecting portion is disposed on one end of the terminal position guarantee member, and the plurality of blocking portions are disposed on the connecting portion. The blocking portions correspond to the positions of the signal pressure terminals.

[0010] Furthermore, the upper and lower sides of the blocking portion are more inclined towards the center the further away from the terminal position guarantee member they are from the blocking portion.

[0011] Furthermore, it also includes a stabilizing member disposed at the other end of the terminal position guarantee member. The stabilizing member is located outside the housing and has multiple receiving slots on it, with the cable disposed in the corresponding receiving slot.

[0012] Furthermore, the housing is provided with an insertion groove that matches the shape of the terminal position guarantee component.

[0013] Furthermore, the housing is provided with multiple spacer cavities to accommodate the signal crimping terminals and the cable. After the terminal position guarantee is inserted into the housing, the connecting part drives each of the blocking parts into the corresponding spacer cavity, and the blocking part located in each spacer cavity contacts the insulation of the corresponding signal crimping terminal.

[0014] Furthermore, the elastic element, buckle, terminal position guarantee element, blocking element, and stabilizing element are integrally formed.

[0015] The following are the beneficial effects of implementing this utility model: This application provides a terminal position guarantee that is inserted into a housing and mates with multiple signal wire terminals. The insertion end of the terminal position guarantee is provided with a blocking member that can abut against the insulation of each signal wire terminal. Both sides of the terminal position guarantee are provided with limiting members that can mate with the housing to limit the terminal position guarantee within the housing. After the signal wire terminals, carrying the cable, are installed into the housing, the terminal position retainer is inserted into the housing. This causes the blocking element to abut against the front end of the insulation of each signal wire terminal. Simultaneously, the limiting elements on both sides of the terminal position retainer cooperate with the housing to confine the terminal position retainer and the blocking element within the housing, keeping them relatively stationary. The blocking element's contact with the front end of the insulation of each signal wire terminal further locks the signal wire terminals into the housing, increasing the holding force between the signal wire terminals and the housing. This reduces the risk of the signal wire terminals detaching from the housing and failing, thereby improving the stability and secureness of the signal wire terminals within the housing, facilitating installation, extending service life, and enhancing signal transmission stability.

[0021] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0022] Please see Figures 1 to 6 The wire-end connector in the first embodiment of this utility model includes: a housing 1 and multiple power crimp terminals and multiple signal crimp terminals 2 inserted into the housing 1. For each signal crimp terminal 2, a corresponding anti-retraction structure is provided in the signal terminal insertion hole of the housing 1. It also includes a terminal position guarantee member 6 inserted into the housing 1 and cooperating with the multiple signal crimp terminals 2. The insertion end of the terminal position guarantee member 6 is provided with a blocking member 7 that can respectively abut against the insulating sheath 21 of each signal crimp terminal 2. Limiting members 8 are provided on both sides of the terminal position guarantee member 6, which can cooperate with the housing 1 to limit the terminal position guarantee member 6 within the housing 1.

[0023] This application includes a terminal position guarantee member 6 inserted into the housing 1 and cooperating with multiple signal wire terminals 2. The insertion end of the terminal position guarantee member 6 is provided with a blocking member 7 that can abut against the insulating skin 21 of each signal wire terminal 2. The two sides of the terminal position guarantee member 6 are respectively provided with limiting members 8 that can cooperate with the housing 1 to limit the terminal position guarantee member 6 in the housing 1. After the signal terminal 2 carrying the cable 3 is installed into the housing 1, the terminal position guarantee 6 is inserted into the housing 1, so that the blocking member 7 abuts against the front end of the insulation 21 of each signal terminal 2. At the same time, the limiting members 8 on both sides of the terminal position guarantee 6 cooperate with the housing 1 to limit the terminal position guarantee 6 and the blocking member 7 in the housing 1, so that the terminal position guarantee 6 and the housing 1 remain relatively stationary. By using the blocking member 7 to abut against the front end of the insulation 21 of each signal terminal 2, the signal terminal 2 can be further locked in the housing 1, which increases the holding force between the signal terminal 2 and the housing 1, thereby reducing the risk of the signal terminal 2 falling out of the housing 1 and failing. This improves the stability and firmness of the signal terminal 2 in the housing 1, facilitates installation, extends service life, and improves the stability of signal transmission.

[0024] Specifically, by installing the terminal position guarantee 6 inside the housing 1, the blocking member 7 abuts against the front end of the insulation skin 21 of each signal wire terminal 2, reducing the pressure applied to the signal wire terminal 2 and preventing deformation of the signal wire terminal 2 that would affect operation. By setting an opening on the housing 1 and inserting the terminal position guarantee 6 into it, the signal wire terminal 2 can be locked in a secondary manner, which facilitates manufacturing and operation, improves the stability and firmness of the signal wire terminal 2 inside the housing 1, and reduces the risk of the signal wire terminal 2 falling out of the housing 1 and failing.

[0025] Please see Figures 1 to 6 In some embodiments, the limiting member 8 includes an elastic member 81 and a buckle 82. A limiting groove 83 is provided on the housing 1. The elastic member 81 is disposed on the terminal position guarantee member 6, and the buckle 82 is disposed on the elastic member 81. After the terminal position guarantee member 6 enters the housing 1, the elastic member 81 drives the buckle 82 into the limiting groove 83.

[0026] This application utilizes a limiting groove 83 on the housing 1, an elastic element 81 mounted on the terminal position retainer 6, and a latch 82 mounted on the elastic element 81. After the terminal position retainer 6 enters the housing 1, the elastic element 81 drives the latch 82 into the limiting groove 83. After the terminal position retainer 6, along with the blocking element 7, comes into contact with the insulation 21 of the signal wire terminal 2, the elastic elements 81 on both sides of the terminal position retainer 6 will drive the latch 82 to engage with the limiting groove 83, locking the terminal position retainer 6 within the housing 1. Under the action of the elastic element 81, simply inserting the terminal position retainer 6 into place will automatically drive the latch 82 into the limiting groove 83, making operation simpler and more convenient, facilitating installation, and improving installation efficiency. To remove the terminal position guarantee 6, simply insert two fingers into the limiting groove 83 and press the buckle 82 inward against the elastic force of the elastic member 81, causing the buckles 82 on both sides to move out of the limiting groove 83. Then, pull out the terminal position guarantee 6. This makes the operation easier and allows the terminal position guarantee 6 to be detachably installed in the housing 1 to perform a secondary locking of the signal wire terminal 2, making it suitable for more usage environments.

[0027] The latch 82 can be dome-shaped or trapezoidal. The dome-shaped latch 82 is more wear-resistant, less prone to deformation, and easier to remove from the limiting groove 83, making it suitable for environments where the terminal position guarantee 6 needs to be disassembled multiple times. The trapezoidal latch 82 can fit more tightly with the limiting groove 83, providing a more secure and stable position for the terminal position guarantee 6. Therefore, different shapes of latches 82 can be selected according to the on-site environment, expanding the range of applications and making the use more flexible and versatile.

[0028] Please see Figures 1 to 6 In some embodiments, the end of the elastic member 81 moves further away from the latch 82 and closer to the terminal position guarantee member 6 until it comes into contact with the terminal position guarantee member 6.

[0029] This application utilizes the principle that the end of the elastic member 81 moves further away from the latch 82 and closer to the terminal position guarantee member 6 until it comes into contact with the terminal position guarantee member 6. By widening the end of the elastic member 81 as it moves closer to the terminal position guarantee member 6, the widest part of the elastic member 81 comes into contact with the terminal position guarantee member 6, increasing the connection strength between them and improving the secondary locking force on the signal wire terminal 2. The elastic member 81 is trapezoidal, with the width of the end closer to the latch 82 being smaller than the width of the end farther from the latch 82. This creates a larger gap between the end of the elastic member 81 closer to the latch 82 and the terminal position guarantee member 6, reducing obstruction during deformation and allowing the elastic member 81 to more smoothly move the latch 82 into or out of the limiting groove 83. This improves the smoothness of installing or removing the terminal position guarantee member 6, reduces the space occupied by the elastic member 81, and makes operation more effortless and convenient.

[0030] Please see Figures 1 to 6 In some embodiments, the snap fastener 82 is provided with a bevel 84 on the side near the housing 1 that is inclined toward the terminal position guarantee member 6.

[0031] This application provides a beveled surface 84 inclined towards the terminal position guarantee member 6 on the side of the buckle 82 near the housing 1. After the buckle 82 enters the limiting groove 83, the beveled surface 84 hooks onto the outer wall of the limiting groove 83. The beveled surface 84 makes it difficult for the buckle 82 to separate from the limiting groove 83, which can improve the firmness of the buckle 82 after it is engaged with the limiting groove 83, improve the locking force of the blocking member 7 on the signal wire terminal 2, and thus improve the stability and firmness of the signal wire terminal 2 in the housing 1, reducing the risk of the signal wire terminal 2 falling out of the housing 1 and failing.

[0032] Please see Figures 1 to 6 In some embodiments, the blocking member 7 includes a connecting part 71 and a plurality of blocking parts 72. The connecting part 71 is disposed on one end of the terminal position guarantee member 6, and the plurality of blocking parts 72 are disposed on the connecting part 71. The blocking parts 72 correspond to the positions of the signal pressure terminal 2.

[0033] This application provides a connecting portion 71 on one end of the terminal position guarantee member 6, and multiple blocking portions 72 are provided on the connecting portion 71, with the blocking portions 72 corresponding to the positions of the signal wire terminals 2. The connecting portion 71 increases the connection strength between the elastic member 81 and the terminal position guarantee member 6, and by using multiple blocking portions 72 corresponding to different signal wire terminals 2, the blocking portions 72 do not affect adjacent signal wire terminals 2 when they come into contact with the insulating sheath 21 of the signal wire terminals 2. Depending on the actual usage environment, each blocking part 72 can be set to a different length to adjust the squeezing force on the insulation 21 of each signal terminal 2. In particular, for the signal terminals 2 located on both sides, the deformation of the edge of the shell 1 is the greatest when the connector is plugged in or unplugged. By increasing the length of the blocking parts 72 on both sides, the limiting strength of the blocking parts 72 on both sides for the signal terminals 2 is improved, thereby improving the stability and firmness of the signal terminals 2 on both sides when the connector is plugged in or unplugged. Different lengths of blocking parts 72 can be selected according to the actual usage conditions, expanding the applicable range and making the use more flexible and versatile.

[0034] Please see Figures 1 to 6 In some embodiments, the upper and lower sides of the blocking portion 72 are more inclined toward the center the further away from the terminal position guarantee member 6.

[0035] This application utilizes a design where the upper and lower sides of the blocking portion 72 are inclined towards the center as they move further away from the terminal position retainer 6. The lower side of the blocking portion 72 is inclined towards the center, allowing space to be provided on the lower side. This prevents the blocking portion 72 from contacting the signal terminal 2 and affecting signal transmission, ensuring that the end of the blocking portion 72 only contacts the insulation 21 of the signal terminal 2, thus providing a secondary locking of the signal terminal 2. The upper side of the blocking portion 72 is inclined towards the center, saving space inside the housing 1 and ensuring that the end of the blocking portion 72 fully contacts the insulation 21 of the signal terminal 2, improving the limiting ability of the signal terminal 2. This enhances the stability and firmness of the signal terminal 2 within the housing 1, reducing the risk of the signal terminal 2 detaching from the housing 1 and failing.

[0036] Please see Figures 1 to 6 In some embodiments, a stabilizing member 9 is also provided at the other end of the terminal position guarantee member 6. The stabilizing member 9 is located outside the housing 1 and is provided with a plurality of receiving grooves 91, in which the cable 3 is disposed.

[0037] This application utilizes a retaining member 9 located at the other end of the terminal position guarantee 6. The retaining member 9 is situated outside the housing 1 and has multiple receiving slots 91, in which the cable 3 is positioned. By placing the cable 3 within the receiving slots 91, the connection between the retaining member 9 and the terminal position guarantee 6 further enhances the stability and firmness of the terminal position guarantee 6 within the housing 1 in the lateral direction, thereby improving the locking capability of the signal terminal 2. The retaining member 9, located outside the housing 1, facilitates the installation and removal of the terminal position guarantee 6, making the operation more convenient and effortless, and improving installation efficiency. The retaining member 9 also enhances the bending resistance of the terminal position guarantee 6, extending its service life.

[0038] Please see Figures 1 to 7 In some embodiments, the housing 1 is provided with an insertion groove 4 that is identical in shape to the terminal position guarantee member 6.

[0039] This application provides an insertion groove 4 on the housing 1 that matches the shape of the terminal position guarantee 6. The terminal position guarantee 6 enters the housing 1 through the insertion groove 4. The insertion groove 4, which matches the shape of the terminal position guarantee 6, can more stably limit the terminal position guarantee 6 in the housing 1, reduce the shaking of the terminal position guarantee 6 in the housing 1, improve the stability of the terminal position guarantee 6 in the housing 1, expand the scope of application, and thus improve the secondary locking capability of the blocking part 72 for the signal wire terminal 2, reducing the risk of the signal wire terminal 2 falling out of the housing 1 and failing.

[0040] Please see Figures 1 to 7 In some embodiments, the housing 1 is provided with a plurality of spacer cavities 5 for accommodating signal wire terminals 2 and cables 3. After the terminal position guarantee member 6 is inserted into the housing 1, the connecting part 71 drives each blocking part 72 into the corresponding spacer cavity 5. The blocking part 72 located in each spacer cavity 5 contacts the insulation 21 of the corresponding signal wire terminal 2.

[0041] This application utilizes a housing 1 with multiple spacer cavities 5 within it to accommodate signal pin terminals 2 and cables 3. After the terminal position guarantee member 6 is inserted into the housing 1, the connecting part 71 drives each blocking part 72 into its corresponding spacer cavity 5. The blocking part 72 in each spacer cavity 5 contacts the insulation 21 of the corresponding signal pin terminal 2. The connecting part 71 drives each blocking part 72 into its corresponding spacer cavity 5 to contact the insulation 21 of the corresponding signal pin terminal 2. The inner wall of the spacer cavity 5 confines the blocking part 72 within it, improving the lateral stability of the blocking part 72 and thus enhancing its secondary locking capability for the signal pin terminal 2. The connecting part 71 connects to the blocking part 72 and the terminal position guarantee member 6, improving the lateral stability of the terminal position guarantee member 6 within the housing 1. This, in turn, enhances the stability and security of the signal pin terminal 2 within the housing 1, reducing the risk of the signal pin terminal 2 detaching from the housing 1 and failing.

[0042] The partition cavity 5 can also reduce the intrusion of dust, ensure the stability of signal transmission, and extend the service life of the internal signal wire terminals 2 and terminal position guarantee components 6.

[0043] Please see Figures 1 to 6 In some embodiments, the elastic element 81, the snap fastener 82, the terminal position guarantee element 6, the blocking element 7, and the stabilizing element 9 are integrally formed structures.

[0044] This application uses an integrally formed structure of elastic element 81, snap fastener 82, terminal position guarantee element 6, blocking element 7, and stabilizing element 9. The integrally formed elastic element 81, snap fastener 82, terminal position guarantee element 6, blocking element 7, and stabilizing element 9 can improve the connection strength between them, extend the service life, facilitate manufacturing, enable rapid mass production, and be suitable for more application environments.

It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model.
