[0032] [First Embodiment]
[0033] As Figure 1-6 shown is a four-terminal female head connector provided by the first embodiment of the present utility model, which includes a housing 1 and a main body 2 located inside the housing 1. The main body 2 extends out from the rear end of the housing 1 and is connected with a cable 22. The other end of the cable 22 is connected to a terminal 21 at the front end inside the main body 2. To shield the interference of non-expected signals, a shielding ring 23 is arranged between the outer edge of the cable 22 and the inner wall of the main body 2. Four main bodies 2 are arranged inside the housing 1 in a square layout. By using multiple terminals, the signal transmission stability of the signal connection device is improved. Arranging the four terminals in a square layout is beneficial to saving space and facilitating the molding of the corresponding housing and main body. Locking members 3 are symmetrically arranged on both sides of the housing 1. A main body limiting groove 24 for limiting cooperation with the locking members 3 is formed on the outer edge of the main body 2. The main body 2 realizes axial limitation inside the housing 1 through the limiting cooperation with the locking members 3 on both sides; by symmetrically arranging the locking members on both sides of the housing, the main body realizes axial limitation inside the housing through the limiting cooperation with the locking members on both sides, so as to replace the scheme of arranging a positioning structure inside the housing in the prior art. While reducing the process time-consuming and cost, when replacing and maintaining the terminals, it only needs to complete by loading and unloading the locking members, which is quick to load and unload and convenient for maintenance. At the same time, by symmetrically arranging the locking members on both sides of the housing, the main body realizes axial limitation inside the housing through the limiting cooperation with the locking members on both sides, thereby realizing the radial limitation and axial limitation of the terminals inside the housing at the same time, and ensuring the stable all-directional limitation of the multiple terminals inside the housing.
[0034] AsFigure 1 As shown, the housing 1 includes a front housing 11 and a rear housing 12 which are connected to each other. The front housing 11 is provided with a circular cross-section, and the rear housing 12 is provided with a square cross-section, so as to facilitate the molding of the housing. At the same time, the stepped connection position formed by the cross-sectional shapes of different shapes is also beneficial to the axial limiting effect when plugging and matching with the corresponding male connector.
[0035] To achieve the plugging and matching with the corresponding male connector, a plugging limiting portion 111 is provided at the top of the outer edge of the front housing 11, and a plugging limiting groove 121 is provided at the top of the outer edge of the rear housing 12. After the male connector presses the plugging limiting portion 111 to elastically contract, it enters the inside of the plugging limiting groove 121, thereby realizing the plugging and matching of the female connector with the corresponding male connector. To facilitate the plugging operation, holding grooves 122 are opened on both sides of the outer edge of the rear housing 12.
[0036] As Figure 6 shown, the locking member 3 in this embodiment includes a locking body portion 31, a rear housing locking portion 32 fixed to the front side of the locking body portion 31, and a front housing locking portion 33 fixed to the front side of the rear housing locking portion 32. Correspondingly, front housing locking grooves 112 for cooperating with the locking member 3 are opened on both sides of the outer edge of the front housing 11, and rear housing locking grooves 123 and rear housing locking holes 124 for cooperating with the locking member 3 are respectively opened on both sides of the outer edge of the rear housing 12. The front housing locking portion 33 can extend into the inside of the front housing locking groove 112 and cooperate with it correspondingly, the rear housing locking portion 32 can extend into the inside of the rear housing locking groove 123 and cooperate with it correspondingly, and the locking body portion 31 can extend into the inside of the rear housing locking hole 124 and cooperate with it correspondingly.
[0037] As a preference of this embodiment, the locking body portion 31 includes upper locking teeth 311 located at the top of the main body 2, middle locking teeth 312 located in the middle of the main body 2, and lower locking teeth 313 located at the bottom of the main body 2. The intervals between multiple terminals are realized through the locking teeth, reducing the possibility of safety risks caused by the mutual contact of multiple terminals during transportation and use;
[0038] As Figure 5-6 shown, radial limiting grooves 125 for cooperating with the locking member 3 are respectively opened at the top and bottom of the inner wall of the rear housing 12. Radial limiting portions 3111 corresponding to the radial limiting grooves 125 are respectively protruded at the top of the upper locking teeth 311 and the bottom of the lower locking teeth 313, so as to achieve the stable limiting effect of the locking member 3 inside the housing 1.
[0039] Axial limiting portions 3121 corresponding to the main body 2 are respectively provided at the bottom of the upper locking teeth 311, the top and bottom of the middle locking teeth 312, and the top of the lower locking teeth 313. The stable axial limiting of multiple terminals inside the housing 1 is realized through the corresponding cooperation of the axial limiting portions 3121 and the main body limiting grooves 24.
[0040] On both outer edges of the locking body part 31, there are also provided hand-held parts 310 to facilitate the hand-held operation of the locking member 3.
[0041] Such as Figure 2 and 6 As shown, on both sides of the outer edge of the rear housing 12, there are provided rear housing positioning parts 126 that cooperate with the locking member 3. Inside the rear housing locking part 32, there is opened a rear housing positioning hole 321 that corresponds to and cooperates with the rear housing positioning part 126 to realize the positioning and installation of the locking member 3 on both sides of the housing 1.
[0042] When this embodiment is working specifically:
[0043] First, push the main body 2 into the corresponding position inside the housing 1 until the main body limit groove 24 is aligned with the rear housing locking hole 124;
[0044] Then, push and install the locking member 3 on both sides of the housing 1 respectively, so that the front housing locking part 33 extends into the inside of the front housing locking groove 112 and cooperates with it correspondingly, the rear housing locking part 32 extends into the inside of the rear housing locking groove 123 and cooperates with it correspondingly, and the locking body part 31 extends into the inside of the rear housing locking hole 124 and cooperates with it correspondingly; and ensure that the upper locking teeth 311 are located at the top of the main body 2, the middle locking teeth 312 are located in the middle of the main body 2, and the lower locking teeth 313 are located at the bottom of the main body 2; and ensure that the axial limiting part 3121 is snapped into the main body limit groove 24 inside to realize the stable axial limiting of multiple terminals inside the housing 1;
[0045] Then, continue to push and install the locking member 3 until the rear housing positioning part 126 enters the rear housing positioning hole 321 inside, and the radial limiting part 3111 is snapped into the radial limiting grooves 125 at the top and bottom of the housing, thereby realizing the fixation of the locking member 3 on both sides of the housing 1.
