收納部中，從而可利用該彈性構件的恢復力來實現連接器 的浮動。 如中國專利ZL200520049751.9公開的一種多頭同軸微 電纜的浮動連接器，其包括一連接器本體，具有一第一端 部及一第二端部，該第一端部上設有至少二個收容孔可用 以接納至少二個公插頭，該連接器本體可容許多個公插頭 對另一個母連接器中的多個母接頭做同心浮動以便利插接 操作。其中，實現浮動的具體方式可以是如該中國專利的

Referring to FIG. 3, FIG. 4, FIG. 9 and FIG. 10, the front case 3 is made of an insulating material, and has a panel 35 on the front side thereof, and a first receiving groove 32 and a second receiving groove are recessed on the rear side surface thereof. The first receiving slot 32 is for receiving the first connector assembly 1 . The second receiving slot 34 is for receiving the second connector 2 correspondingly. A first window 31 and a second window 33 are defined on the panel 35. The first window 31 is configured for forwardly connecting the mating end of the first connector 11 and the first connector 11 is A gap d is disposed between the first windows 31 for the first connector 11 to float freely up, down, left, and right within the range of the gap d. The inner wall 321 of the first receiving slot 32 has a stepped structure, and has a rearward, larger first portion 322 for receiving the first spacer 15 and a second, smaller second portion 323 for corresponding receiving. The second spacer 16 is in close contact with the side plate 161 of the second spacer 16 while leaving between the first portion 322 and the sidewall 152 of the first spacer 15 There is a gap to facilitate fitting the spacer unit 13 into the first receiving groove 32. Correspondingly, the second window 33 is provided for the mating end of the second connector 2 to be forwarded 9 M426185. As shown in FIG. 10, when the spacer unit 13 is assembled in the first receiving slot 32, the front housing 3 and the first and second spacers 15 and 16 cooperate to form an accommodating space for receiving the elastic member 12. The elastic member 12 is elastically deformable in accordance with the floating correspondence of the first connector 11. The front and rear sides of the body 121 of the elastic member 12 are respectively in contact with the front case 3 and the substrate 1S1 of the first spacer I5, and the tail portion I24 of the elastic member 12 and the first wire 51 covered therein can pass through the first The through hole 153 of the spacer 15 protrudes rearward to close the through hole 153. The spacing unit I3 embosses the body 1 of the elastic member I2, and the protrusion I22 and the recess I23 are accommodated in the accommodating space, and are overmolded with The rear case 4 at the rear end of the spacer unit 13 is separated. Therefore, it is possible to infiltrate the molten plastic into the accommodating space of the elastic member I2 when the inner casing 4 is molded, so as to avoid the body 121 of the press-fitting member I2 and to fill the recess 123, thereby causing the elastic member 12 to lose its elasticity. Referring to FIG. 2 and FIG. 1 , the rear case 4 is made of a rigid plastic material, which includes an inner casing 41 of a pE (polyethylene 'polyethylene) material directly overmolded behind the spacer unit 13 and repackaged. An outer casing 42 of a TPE ( Thermoplastic Elastomer, 1 , 1, 2, 2-tetrastyrene) material overmolded on the outer core of the PE. The rear shell 4 adopts a process of independent molding in the south, and is reshaped on the outer circumference of the inner shell 41 having a thick wall thickness - a shell 42' having a thin wall surface, thereby reducing the influence of the shrinkage of the plastic material after the injection molding. To prevent the appearance of the rear case 4 from being defective. The first connector u and the first connector 2 can be fixed together by the cooperation of the front case 3 and the rear case 4 to form a two-in-one floating connector, 10 M426185. The second connector 2 is preferably implemented in the present invention. In the example, the front housing 3 is inactively fixed, while in other possible embodiments the second connector 2 can be eliminated or can be designed to be floatably mounted on the front housing 3. The first connector 11 can be floated up and down and left and right with respect to the front case 3, so that the influence of manufacturing assembly tolerance can be easily overcome. The two-in-one floating connector can be smoothly inserted into another docking socket (Fig. Show). Referring to FIG. 11, the preferred embodiment of the novel floating connector can be specifically applied to a cable connector, wherein the other end of the plurality of first wires 51 is electrically connected to a third connector 6; The other end of the two wires 52 is electrically connected to a fourth connector 7. The manufacturing process of the floating connector of the present invention generally comprises: firstly arranging the spacer unit 13 on the first wire 51; then connecting the terminal of the first wire 51 to the terminal of the conductive terminal 112 on the first connector 11. 1122 is welded together; the elastic member 12 is overmolded on the outer periphery of the rear portion of the first connector 11; then the spacer unit 13 is sleeved forwardly on the outer side of the elastic member 12: then the second connector 2 is then A similar wire bonding and injection molding process the overcladding body 22, and then the assembled first connector assembly 1 is mounted into the first receiving groove 32 of the front case 3 and the first connector 11 is protruded forward. Extending the first window 31; similarly, the second connector 2 is mounted to the second receiving slot 34 of the front case 3 and the second connector 2 is projected forwardly out of the second window 33; finally in the front case 3 The rear end is overmolded to form the inner casing 41, and the outer casing 42 is overmolded. Compared with the prior art, the floating connector of the present invention has the beneficial effects of preventing the 11 M426185 elastic member 12 from being separated from the rear case 4 by providing a spacer unit 13 behind the elastic member I2, thereby preventing the molding after the molding. The plastic melted at the time of the shell 4 penetrates into the outer periphery of the elastic member 12 under the pressure of injection molding, so that the elastic member 12 loses its elasticity and causes the first connector U to be freely floatable; and the spacer unit 13 is formed in cooperation with the front case 3. The accommodating space can also enclose the elastic member 12 to prevent it from falling off and aging; and the rear case 4 holds a part of the first wire 51 in the same manner to protect the connection point between the first wire 51 and the conductive terminal 112. Preventing the pulling force acting on the cable 5 from being transmitted to the connection point causes the connection point to be damaged. The above is only a preferred embodiment of the present invention, and is not intended to limit the embodiments of the present invention. Those skilled in the art can make corresponding modifications or modifications in a very convenient manner according to the main idea and spirit of the present invention, for example, The elastic member 12 can also be replaced by an elastic ring tube which is sleeved on the outer circumference of the rear portion of the first connector. Therefore, the protection scope of the present invention should be based on the protection scope required by the patent application scope.
